AWS re:Invent History and Timeline - Keynotes, Major Announcements, and Evolution by Year

First Published:
Last Updated:

This is another installment in the series that I started with the "AWS History and Timeline - Almost All AWS Services List, Announcements, General Availability(GA)", where I extract features from the history and timeline of AWS. In the per-service articles I follow a single service such as Amazon EC2, AWS Lambda, Amazon S3, or Amazon Bedrock; in the cross-cutting AWS Generative AI History and Timeline I follow a whole domain.

This time, instead of following a service or a domain, I follow an event: AWS re:Invent, the annual flagship learning conference that Amazon Web Services has held since 2012. re:Invent is where AWS concentrates the largest share of its yearly launches - a single week (three weeks in 2020) that has introduced Amazon Redshift, AWS Lambda, Amazon Aurora, Amazon SageMaker, Amazon EKS, AWS Fargate, Amazon Q, Amazon Nova, and hundreds of other services and features. Because so many "when did AWS launch X?" answers trace back to a specific re:Invent keynote, a year-by-year index of the conference is a useful map in its own right.

The name itself signals the intent. "re:Invent" belongs to AWS's family of "re:" event names - alongside AWS re:Inforce (security) and the former AWS re:Mars - and frames the conference as a place to rethink how applications are built on the cloud. In practice it functions as AWS's product-launch moment of the year: a large share of major services debut here, often first as previews shown on stage and later reaching general availability, so the conference doubles as both a learning event and the anchor of the AWS release calendar. That dual role is why a re:Invent-centric timeline complements the per-service timelines: the per-service pages answer "how did service X evolve?", while this page answers "what did AWS choose to put on stage in year Y, and where can I read more?".

This article organizes AWS re:Invent as a one-row-per-edition timeline from the first re:Invent in 2012 to re:Invent 2025. Each row records the edition's dates, host city, format (in-person, fully virtual, or hybrid), keynote pillars, and a curated set of representative major announcements, each linked to its official AWS source and, where a companion timeline exists on this site, to the deeper per-service history. This makes the page a "hub of hubs": from any edition you can jump straight into the full history of the service that edition launched.

For readers who want to jump directly to a specific part, the article is structured as follows:
There is also a practical reason to keep a page like this. Interest in AWS re:Invent is strongly seasonal: search and reference traffic spikes every November and December as the conference approaches and again as people look back to confirm "which year did that launch happen?". A year-indexed record is exactly the shape that both human readers and AI search agents want to consult during that window, and it compounds in value each December when a single new row and a handful of Deep-Dive links are added. This article is designed to be that durable, citable index - each edition in one place, each announcement traceable to an official AWS URL.

I hope this timeline provides clues about what has stayed the same and what has changed about AWS re:Invent, in addition to serving as an entry point into the history of the individual AWS services announced there.

Background and Method of Creating This AWS re:Invent Timeline

The reason for creating a historical timeline of AWS re:Invent is that the conference has become the single most important date on the AWS release calendar, and yet its history is scattered across dozens of keynote recaps, "top announcements" posts, and individual service launch blogs. When someone asks "which re:Invent introduced AWS Lambda?" or "was Amazon Q announced in 2023 or 2024?", the answer usually lives inside one specific keynote in one specific year. A compact, year-indexed record makes those questions answerable in a single fetch.

Another reason is that re:Invent itself has evolved. It grew from a single 6,000-attendee event at one Las Vegas hotel in 2012 to a 60,000-plus-attendee, multi-venue conference; it went fully virtual and free for three weeks in 2020; and it returned as a hybrid event that streams its keynotes worldwide. Tracking the event by year captures that evolution of scale and format alongside the announcements.

There is also a practitioner angle. For many engineers, architects, and technical decision-makers, re:Invent is the single moment each year when they take stock of what changed on AWS, decide what to evaluate, and update their mental model of the platform. The conference has grown a large surrounding ecosystem - partner announcements, community-led sessions, certification activity, and a wave of follow-up blog posts and recap videos. A concise, year-indexed record of the headline launches is a useful anchor for that annual stock-take, and for anyone who later needs to reconstruct when a capability first appeared. I organized the information with the following approaches.
  • Tracking the history of AWS re:Invent and organizing each edition's dates, format, keynotes, and representative announcements
  • Summarizing, for each edition, a curated set of major announcements rather than an exhaustive list
How the representative announcements are selected. re:Invent routinely ships more than a hundred launches per edition, so any timeline has to curate. To keep the selection principled rather than arbitrary, the announcements in each row are chosen using two filters applied in order:
  • First, what AWS itself highlighted. Candidate announcements are drawn from AWS's own official "Top announcements of AWS re:Invent" recap posts and the keynote live blogs on the AWS News Blog, not from third-party coverage. If AWS did not surface an announcement as a headline of that edition, it is generally not included here.
  • Second, what connects to a deeper history on this site. Among those AWS-highlighted announcements, I preferentially include the launches that started or materially advanced a service that already has a dedicated per-service timeline on this site, so that each row can link out to the full chronology of that service. A few widely recognized launches without a companion timeline (for example AWS Firecracker or AWS Outposts) are included for completeness of the historical record.
This timeline primarily references the following official AWS sources.
There may be slight variations in the dates on the timeline because re:Invent announcements are spread across several days - the Monday Night Live infrastructure keynote, the Tuesday CEO keynote, the mid-week data and AI keynote, and the Thursday closing keynote - and AWS What's New posts are sometimes dated the day before or after the keynote in which a feature was shown. For that reason the Date column shows each edition's full span rather than a single day, and the sentences note preview versus general availability (GA) where the distinction matters. Where an official AWS URL states a different day than a keynote recap, I follow the primary source URL.
The content posted is limited to major, AWS-highlighted announcements needed to understand each edition and to connect it to the per-service timelines.
In other words, please note that the items on this timeline are not all of the announcements made at each re:Invent, but are representative announcements that I have picked out. For the exhaustive list of any edition, use AWS's own "Top announcements" recap post linked in that year's row; for a service's full history, use the per-service timeline linked from the row.

A word on preview versus general availability (GA). re:Invent is frequently where a service is first shown, often as a preview or even a pre-announcement, with GA arriving months later. Amazon Aurora, AWS Lambda, Amazon EKS, Amazon Aurora Serverless, and Amazon Aurora Limitless Database were all introduced as previews at one re:Invent and reached GA afterward. This timeline attributes an announcement to the edition where AWS first presented it and labels it as a preview or pre-announcement where that was the case; the later GA date, when it matters, is recorded in the linked per-service timeline. That is deliberate: the point of this page is to answer "which re:Invent introduced X?", which is a question about first appearance, not about GA.

Finally, this is a living document rather than a fixed history. Each year after re:Invent, a new row is added for the latest edition, the representative announcements are chosen using the same two filters, and any new per-service timelines on this site are linked from the relevant rows. The URL of this page does not change as it grows, so links and citations to it remain stable over time.

AWS re:Invent Historical Timeline (Editions from 2012 to 2025)

Now, here is the year-by-year timeline of AWS re:Invent. As of the time of writing, there have been 14 editions from the first re:Invent in November 2012 through re:Invent 2025. Each row covers one edition; the Date column shows the conference span, and the Summary column gives the location, format, keynote pillars, and representative announcements (each linked to its official AWS source, and to the per-service timeline where one exists).

The table is sorted in ascending order, from the oldest edition at the top to the most recent at the bottom, so it reads as a chronological narrative. Each row carries an anchor id equal to its year (for example #2023), so you can link directly to a specific edition, and the year index above jumps to any edition in one click. Where a representative announcement was a preview or pre-announcement, the sentence says so; the general availability date, when relevant, is recorded in the linked per-service timeline rather than repeated here.

2012 | 2013 | 2014 | 2015 | 2016 | 2017 | 2018 | 2019 | 2020 | 2021 | 2022 | 2023 | 2024 | 2025

Date Summary
2012-11-27 – 2012-11-29 The first-ever AWS re:Invent is held in Las Vegas, establishing AWS's annual flagship conference. It launched a tradition that has run every year since and turned late autumn into the busiest stretch of the AWS release calendar. Held November 27–29, 2012 at The Venetian, the inaugural re:Invent drew roughly 6,000 attendees. Andy Jassy delivered the Day 1 keynote and Werner Vogels the Day 2 keynote, which closed with a widely watched fireside chat between Amazon's Jeff Bezos and Werner Vogels. Representative announcements:
  • Amazon Redshift is introduced in limited preview as a fast, fully managed, petabyte-scale data warehouse priced from a fraction of traditional warehouses. [Announcement]
  • AWS Data Pipeline is announced for orchestrating and automating the movement and transformation of data across AWS services and on-premises sources. [Announcement]
2013-11-12 – 2013-11-15 AWS re:Invent 2013 expands into real-time data, end-user computing, and audit logging. These launches signaled AWS moving beyond raw compute and storage toward managed, higher-order services, and AWS CloudTrail in particular made AWS auditable enough for regulated industries.

2017-11-27 – 2017-12-01 AWS re:Invent 2017 makes containers and machine learning first-class with Amazon SageMaker, AWS Fargate, and Amazon EKS. Amazon SageMaker gave AWS an end-to-end machine learning platform, while AWS Fargate and Amazon EKS defined how AWS would run containers for years to come. Held November 27 – December 1, 2017 across a multi-venue Strip campus, with keynotes by Andy Jassy and Werner Vogels. Representative announcements:
2018-11-26 – 2018-11-30 AWS re:Invent 2018 pushes into hybrid, custom silicon, and purpose-built databases. AWS Outposts extended AWS into the data center, AWS Firecracker exposed the virtualization technology beneath serverless, and a wave of specialized databases and machine learning services widened the portfolio. Held November 26–30, 2018 across seven Strip venues with more than 50,000 attendees. Peter DeSantis opened Monday Night Live; Andy Jassy and Werner Vogels keynoted. Representative announcements:
  • AWS Firecracker, the open-source microVM technology that underpins AWS Lambda and AWS Fargate, is released. [Announcement]
  • AWS Outposts is announced (preview), bringing AWS-managed infrastructure on-premises. [Announcement]
  • Amazon DynamoDB On-Demand capacity mode launches, adding pay-per-request pricing with no capacity planning. [Announcement]
  • Amazon Textract (document text and data extraction, preview), AWS Lake Formation (data lake setup, preview), and AWS DeepRacer (a reinforcement-learning race car) are announced, along with previews of AWS Control Tower, Amazon QLDB, and Amazon Managed Blockchain. [Textract] [Lake Formation] [DeepRacer] [Keynote roundup]
2019-12-02 – 2019-12-06 AWS re:Invent 2019 emphasizes hybrid, edge, machine learning tooling, and quantum. The general availability of AWS Outposts, the arrival of AWS Wavelength and AWS Local Zones, and the debut of Amazon Braket marked AWS reaching toward the edge and toward entirely new computing models. Held December 2–6, 2019 across six Strip venues with more than 60,000 attendees. Peter DeSantis opened Monday Night Live; Andy Jassy and Werner Vogels keynoted. Representative announcements:
  • AWS Outposts reaches general availability, one year after its preview. [Announcement]
  • Amazon SageMaker Studio, the first integrated development environment for machine learning, launches with SageMaker Autopilot. [Announcement]
  • AWS IAM Access Analyzer launches to identify unintended resource access. [Announcement]

[Wavelength] [Detective] [Braket] [Launch roundup]
2020-11-30 – 2020-12-18 AWS re:Invent 2020 is the first fully virtual re:Invent, a free three-week online event. The pandemic-forced virtual format made re:Invent more accessible than ever, and it permanently added a free global livestream to every edition that followed. Running November 30 – December 18, 2020, it was delivered online across global time zones with no host city. Andy Jassy delivered the CEO keynote, Werner Vogels keynoted from the Netherlands, and Swami Sivasubramanian delivered the first dedicated Machine Learning keynote. Representative announcements:
2021-11-29 – 2021-12-03 AWS re:Invent 2021 marks the tenth anniversary and returns to in-person with a virtual option. The tenth edition leaned hard into custom silicon and serverless data - AWS Graviton3, AWS Trainium, and Amazon Redshift Serverless - themes that would dominate the next several years. Held November 29 – December 3, 2021 in Las Vegas. Adam Selipsky delivered his first re:Invent keynote as AWS CEO; Peter DeSantis, Swami Sivasubramanian, and Werner Vogels also keynoted. Representative announcements:
2022-11-28 – 2022-12-02 AWS re:Invent 2022 centers on zero-ETL, data governance, and event-driven architecture. The zero-ETL integrations and event-driven building blocks announced that year were aimed squarely at removing the custom glue code between AWS data, analytics, and application services. Held November 28 – December 2, 2022 in Las Vegas. Peter DeSantis opened Monday Night Live; Adam Selipsky, Swami Sivasubramanian, Ruba Borno, and Werner Vogels keynoted. Representative announcements:
2023-11-27 – 2023-12-01 AWS re:Invent 2023 launches Amazon Q and puts generative AI at the center. Coming a year after the public arrival of large language models, 2023 was AWS's clearest pivot to generative AI, layering assistants, retrieval, and guardrails on top of Amazon Bedrock. Held November 27 – December 1, 2023 in Las Vegas with about 52,000 attendees. Adam Selipsky delivered the CEO keynote and introduced Amazon Q; Peter DeSantis, Swami Sivasubramanian, and Werner Vogels ("The Frugal Architect") keynoted. Representative announcements:
2024-12-02 – 2024-12-06 AWS re:Invent 2024 introduces the Amazon Nova foundation models under a new AWS CEO. In Matt Garman's first re:Invent as CEO, AWS moved from hosting other companies' models to shipping its own Nova family and pushing Amazon Bedrock toward multi-agent and verifiable AI. Held December 2–6, 2024 in Las Vegas with nearly 60,000 attendees. Matt Garman delivered his first re:Invent keynote as AWS CEO (with a cameo from Andy Jassy to introduce Amazon Nova); Swami Sivasubramanian, Peter DeSantis, and Werner Vogels ("Simplexity") keynoted. Representative announcements:
2025-12-01 – 2025-12-05 AWS re:Invent 2025 is themed around agentic AI, from Amazon Nova 2 to Amazon Bedrock AgentCore. The 2025 edition reframed the whole conference around autonomous agents, aligning AWS's runtime, governance, and silicon - Amazon Bedrock AgentCore, agent policy and evaluations, and AWS Trainium3 - behind agentic AI. Held December 1–5, 2025 in Las Vegas with more than 63,000 in-person attendees and over two million livestream viewers. Matt Garman delivered the CEO keynote; Swami Sivasubramanian (agentic AI), Peter DeSantis with Dave Brown (infrastructure), Ruba Borno (partners), and Werner Vogels (closing) keynoted. AWS's official recap described Vogels' closing keynote as his final keynote after 14 years. [Keynote Recap] Representative announcements:

Current Overview of AWS re:Invent - Keynotes, Session Levels, and How to Follow Announcements

Beyond the year-by-year announcements, AWS re:Invent has a stable structure that has held for most of its history. Understanding that structure makes it easier to know where a given announcement will appear and how to follow the conference, whether you attend in person or watch online.

How AWS re:Invent Has Evolved (2012 to 2025)

Read as a whole, the timeline above tells a story in three dimensions: scale, format, and theme.

Scale. The first re:Invent in 2012 drew around 6,000 attendees to a single hotel. By 2018 the event had crossed 50,000 attendees across seven venues, by 2019 more than 60,000, and re:Invent 2025 reported more than 63,000 in-person attendees plus over two million livestream viewers. The number of breakout sessions grew in step, from a few hundred to more than two thousand, which is why the 100-to-400 session-level system and the "Top announcements" recap posts became necessary just to navigate a single edition.

Format. For most of its life re:Invent has been an in-person Las Vegas event, with two notable exceptions. In 2015 the conference moved to October - the only edition not held in November or December - before settling back into its late-November/early-December slot. In 2020, the COVID-19 pandemic forced a complete reinvention: re:Invent became a free, fully virtual, three-week event running from November 30 to December 18, broadcast across global time zones. That virtual year permanently changed the event; since the in-person return in 2021, re:Invent has been hybrid, streaming its keynotes and Innovation Talks online for free while continuing as a large in-person gathering.

Theme. The subject matter of the keynotes tracks the evolution of the cloud itself. The early editions (2012 to 2015) were dominated by core infrastructure and data services - Amazon Redshift, AWS Lambda, Amazon Aurora, Amazon ECS, and the analytics and IoT wave. The middle editions (2016 to 2019) added managed AI/ML services (Amazon Lex, Amazon Polly, Amazon Rekognition, Amazon SageMaker), containers and Kubernetes (AWS Fargate, Amazon EKS), hybrid and edge computing (AWS Outposts, AWS Wavelength), and custom silicon (AWS Inferentia). The 2020 to 2022 editions emphasized the AWS Nitro System, AWS Graviton and AWS Trainium processors, serverless data (Amazon Redshift Serverless, Amazon Aurora Serverless v2), and zero-ETL. And the most recent editions (2023 to 2025) have been defined by generative and agentic AI - Amazon Q in 2023, the Amazon Nova foundation models in 2024, and an agentic-AI theme built around Amazon Bedrock AgentCore and Amazon Nova 2 in 2025. Following re:Invent year by year is, in effect, following the shifting center of gravity of AWS.

It is worth noting how these three dimensions reinforce one another. The theme shift toward AI raised the stakes of each edition, which drove up attendance and livestream viewership (scale), which in turn made the free virtual livestream introduced in 2020 (format) a permanent fixture so that a global audience could follow the AI announcements in real time. In other words, the 2020 pivot to virtual was not just a pandemic workaround; it changed who could participate in every subsequent re:Invent, at exactly the moment the announcements became most consequential for the broader industry.

Recurring Patterns Across AWS re:Invent

A few patterns recur often enough that they are worth naming, because they help predict where and how the next re:Invent announcement will land:
  • Preview at re:Invent, GA the following year. A large share of re:Invent headlines are previews or pre-announcements. Amazon Aurora (preview 2014, GA 2015), Amazon EKS (preview 2017, GA 2018), and AWS Outposts (preview 2018, GA 2019) all followed this rhythm, which is why several rows above pair a re:Invent preview with a later GA noted in the per-service timeline.
  • The Monday Night Live silicon reveal. Custom hardware - the AWS Nitro System, AWS Graviton, AWS Trainium, and AWS Inferentia - is typically unveiled in the infrastructure keynote rather than the CEO keynote, a pattern visible from Graviton3 (2021) through Trainium3 and Graviton5 (2025).
  • One flagship AI headline per year. Since the mid-2010s, each edition has had a defining AI story: managed AI services (2016), Amazon SageMaker (2017), Amazon Q (2023), the Amazon Nova foundation models (2024), and agentic AI with Amazon Bedrock AgentCore (2025).
  • Rename-and-consolidate. Services are periodically renamed and folded together, most visibly when Amazon CodeWhisperer became part of Amazon Q Developer - a storyline that the AWS Generative AI History and Timeline traces in detail.

AWS re:Invent Keynotes

The keynotes are the spine of re:Invent, and most headline announcements land in one of them. The recurring pattern in recent years is:
  • Monday Night Live - an infrastructure-focused keynote, delivered for many years by Peter DeSantis (and joined by Dave Brown in 2025). This is where silicon (AWS Graviton, AWS Trainium, AWS Inferentia, the AWS Nitro System), networking, and low-level performance work is unveiled.
  • The CEO keynote (Tuesday) - the flagship keynote with the broadest set of launches. Its host reflects AWS's leadership over time: Andy Jassy delivered it from 2012 through 2020, Adam Selipsky from 2021 through 2023, and Matt Garman from 2024 onward.
  • The Data and AI keynote (mid-week) - delivered by Swami Sivasubramanian, covering databases, analytics, machine learning, and, in recent years, generative and agentic AI. The first dedicated Machine Learning keynote was held at the virtual re:Invent 2020.
  • The Partner keynote - delivered in recent years by Ruba Borno, focused on the AWS Partner Network and go-to-market.
  • The closing keynote (Thursday) - delivered by CTO Werner Vogels, traditionally the most architecture- and operations-oriented session, often organized around a theme such as "The Frugal Architect" (2023) or "Simplexity" (2024). AWS's official recap of re:Invent 2025 described that year's closing keynote as Vogels' final keynote after 14 years.
Two long-running traditions help explain why the keynotes are where announcements land. First, the CEO keynote has historically opened with a state-of-AWS narrative - scale, customer stories, and pace of innovation - before rolling through the largest batch of launches; this is the keynote most likely to contain the year's headline. Second, Werner Vogels' closing keynote tends to step back from product launches to a single architectural theme, giving practitioners a lens for the week's announcements rather than more of them. Knowing this division of labor helps set expectations: if you are looking for a specific service launch, it almost certainly appeared in the Monday infrastructure keynote, the Tuesday CEO keynote, or the mid-week data and AI keynote, while the closing keynote is where AWS frames how to think about building well.
Around the keynotes, AWS also runs Innovation Talks (deeper, domain-focused sessions from AWS leaders) and Leadership Sessions (per-domain overviews of strategy and roadmap that often expand on the keynote announcements). The specific lineup has shifted over the years - the dedicated Machine Learning keynote first appeared at the virtual 2020 edition, and the infrastructure keynote grew out of the earlier "Tuesday Night Live" and "Monday Night Live" sessions - but the overall shape of a CEO keynote plus specialized keynotes has been stable. Keynotes and Innovation Talks are streamed live and posted for on-demand replay, so the announcements are accessible even to people who do not attend.

AWS re:Invent Session Levels and Formats

Around the keynotes, re:Invent runs thousands of breakout sessions. Sessions are tagged by depth using a 100-to-400 level scale, a convention that also appears across AWS training and AWS Summits:
  • Level 100 (Introductory) - overviews for those new to a topic or service.
  • Level 200 (Intermediate) - assumes an introductory understanding and goes into more detail.
  • Level 300 (Advanced) - deep dives into a topic, including implementation and best practices.
  • Level 400 (Expert) - the most technical sessions, assuming deep familiarity and covering advanced architecture and internals.
In practice, the level is the fastest way to plan a schedule: newcomers to a service can start at 100 and 200 to build context, while experienced engineers usually head straight to the 300 and 400 sessions for implementation detail and internals. The same scale is used across AWS training and the free session catalog, so a re:Invent session's level is a reliable signal of depth even when you watch the recording afterward rather than attending live.
In addition to breakout sessions, re:Invent offers several hands-on and interactive formats:
  • Chalk talks - small, whiteboard-driven sessions that start with a short overview and then open up to audience questions and live diagramming.
  • Workshops and builders' sessions - hands-on, build-along formats where attendees work in their own AWS accounts, individually or in small groups with an AWS expert.
  • Hackathons and gamified learning - for example the AWS DeepRacer League (autonomous racing with reinforcement learning) and AWS GameDay (team-based, scenario-driven challenges).
  • The Expo and community areas - the AWS Village and partner Expo, plus community spaces including a lounge reserved for attendees who hold AWS Certifications.
The event has been almost entirely hosted in Las Vegas across several hotels and convention centers on the Strip - venues that in recent years have included Caesars Forum, The Venetian, Wynn, Encore, MGM Grand, and Mandalay Bay - with the sole exceptions being the schedule shift to October in 2015 and the fully virtual, free, three-week format in 2020. Since 2021 the event has been hybrid: in-person in Las Vegas with keynotes and Innovation Talks streamed online for free.

How to Follow AWS re:Invent Announcements

Because a single edition can contain more than a hundred launches, AWS provides several official channels for tracking them, and this timeline is built on top of them:
  • What's New with AWS? - the authoritative feed of every launch, filterable by date; the re:Invent week each year produces a dense cluster of posts.
  • The AWS "Top announcements of AWS re:Invent" recap on the AWS News Blog - AWS's own curated summary of each edition's headline launches, and the primary selection source for this article.
  • Keynote and Innovation Talk replays on the AWS re:Invent event site and AWS's video channels.
A practical way to use these channels is to start from the "Top announcements" recap for the year you care about to get AWS's own shortlist, then drop into What's New for the exact dates and specifications, and finally watch the relevant keynote replay for the context and demos. That is essentially the workflow this timeline compresses: the recap and keynote pick the representative announcements, and the What's New (or News Blog) post supplies the official URL and date recorded in each row.

re:Invent is the largest of AWS's events, but not the only one. AWS Summits are free, regional, single-or-few-day events held in cities worldwide throughout the year, and AWS re:Inforce is the security-focused conference. Many features previewed at re:Invent reach general availability - and are re-announced - at these other events or through What's New during the following year, which is why several rows above pair a re:Invent preview with a later GA date noted in the per-service timeline.

Frequently Asked Questions about AWS re:Invent History

Where is AWS re:Invent held?
AWS re:Invent is held in Las Vegas, Nevada, spread across several hotels and convention centers on the Strip. The only exceptions in its history are re:Invent 2015, which was moved to October (but still in Las Vegas), and re:Invent 2020, which had no host city because it was delivered as a fully virtual event. Since 2021 the conference has been hybrid: in-person in Las Vegas with keynotes streamed online for free.
Which major AWS services were first announced at re:Invent?
Many flagship AWS services debuted at re:Invent. Examples by edition include Amazon Redshift (2012); Amazon Kinesis and AWS CloudTrail (2013); AWS Lambda, Amazon Aurora, Amazon ECS, and AWS KMS (2014); Amazon Athena and Amazon Lex (2016); Amazon SageMaker, AWS Fargate, and Amazon EKS (2017); AWS Firecracker and AWS Outposts (2018); Amazon Q (2023); and the Amazon Nova foundation models (2024). Each linked year in the timeline above lists the representative announcements and their official sources.
Was AWS re:Invent ever held online?
Yes. re:Invent 2020 was the first and only fully virtual edition - a free, three-week online event held November 30 – December 18, 2020, with keynotes by Andy Jassy and Werner Vogels and the first dedicated Machine Learning keynote by Swami Sivasubramanian. Since 2021, re:Invent has run as a hybrid event: in-person in Las Vegas, with keynotes and Innovation Talks streamed live and available on demand for free.
Who delivers the AWS re:Invent keynotes?
The recurring keynotes are the Monday Night Live infrastructure keynote (Peter DeSantis, joined by Dave Brown in 2025), the CEO keynote (Andy Jassy through 2020, Adam Selipsky 2021–2023, and Matt Garman from 2024), the Data and AI keynote (Swami Sivasubramanian), the Partner keynote (Ruba Borno in recent years), and the closing keynote by CTO Werner Vogels. AWS's official recap of re:Invent 2025 described that year's closing keynote as Vogels' final keynote after 14 years.
When is the next AWS re:Invent?
As of July 5, 2026, AWS has announced that re:Invent 2026 will take place November 30 – December 4, 2026, in Las Vegas, per the official AWS re:Invent event site. Dates for future editions are confirmed on that page; this timeline is updated with a new row after each re:Invent.
How many announcements does AWS make at re:Invent?
A single re:Invent typically includes well over a hundred launches; AWS described re:Invent 2025 as having more than 500 announcements across the week. This timeline does not attempt to list them all - it curates a small set of representative, AWS-highlighted announcements per edition. For the exhaustive list, use AWS's own "Top announcements of AWS re:Invent" recap post for that year, linked in the timeline.
How is AWS re:Invent different from AWS Summits and AWS re:Inforce?
AWS re:Invent is AWS's largest event - a paid, multi-day global conference held once a year in Las Vegas, where AWS concentrates most of its major annual announcements. AWS Summits are free, regional events held in many cities throughout the year, offering a subset of the content closer to customers. AWS re:Inforce is AWS's dedicated cloud security conference. Features often previewed at re:Invent reach general availability and are re-announced at these other events or through AWS What's New during the following year.
All questions above are answered from the timeline and its linked official AWS sources. This article is reviewed and extended after each AWS re:Invent.

Summary

In this article, I created a year-by-year historical timeline of AWS re:Invent and looked at how the conference and its announcements have evolved.

AWS re:Invent has been AWS's annual flagship conference since the first edition at The Venetian in November 2012. Over fourteen editions it grew from a roughly 6,000-attendee event to a 60,000-plus-attendee, multi-venue conference; it went fully virtual and free for three weeks in 2020; and it returned as a hybrid event that streams its keynotes worldwide. Along the way, re:Invent has been the launch stage for a remarkable share of the AWS portfolio - Amazon Redshift (2012), AWS Lambda and Amazon Aurora (2014), Amazon SageMaker, AWS Fargate, and Amazon EKS (2017), Amazon Q (2023), and the Amazon Nova foundation models (2024), among hundreds of others. Reading the conference by year turns "when did AWS launch X?" into a single lookup, and each row links onward to the full per-service history.

A few threads run through the whole history. re:Invent has consistently been the stage for AWS's biggest bets: serverless and containers in the mid-2010s, custom silicon and hybrid cloud toward the end of the decade, serverless data and zero-ETL in the early 2020s, and generative and agentic AI most recently. It has also settled into a predictable rhythm - a Monday Night Live infrastructure reveal, a Tuesday CEO keynote, a mid-week data and AI keynote, and a Thursday closing keynote from Werner Vogels - with previews on stage that mature into general availability over the following year. Knowing that rhythm makes each new edition easier to read.

Because each row is chosen from AWS's own "Top announcements" recaps and keynote live blogs, and each announcement links to an official AWS source, this page is meant to be a reliable, citable index of re:Invent rather than an exhaustive catalog. I would like to continue monitoring what AWS announces at future editions.

There are a few natural ways to use this page. If you want to confirm when a service first appeared, find the year in the index and follow the announcement link to the official source. If you are studying the direction of AWS, read the timeline top to bottom to watch the themes shift from core infrastructure to AI and agents. If you are preparing for an upcoming re:Invent, skim the most recent editions to see the trajectory the next keynotes are likely to continue. And if you need the complete picture for a single service, follow its per-service timeline from the row where it debuted - that is the "hub of hubs" design at work, with this page as the index and the per-service pages as the deep dives.

In addition, there is also a historical timeline of all AWS services and per-service timelines for the individual services announced at re:Invent, so please have a look if you are interested.
