93 Best AWS re:Invent Sessions from 2021

Caylent Goes to re:Invent

Each year cloud christmas happens in Las Vegas and AWS Santa Clause gifts all the good little architects new features and new ideas for what to build. This magical event is called re:Invent. To celebrate the 10th annual re:Invent the Caylent team was there in force! Luckily the fun doesn’t end when we all go home from Vegas. AWS publishes many of the best sessions on YouTube so we can learn at our leisure. In 2021 AWS released, by our count, 479 recorded sessions from re:Invent, or put another way, about 400 cumulative hours of video. That’s almost 17 days of continuous viewing (we may or may not have watched a few of these on 1.5x speed).

The Caylent team popped some popcorn, sat back, and watched every single talk. Why? First of all, it’s our job and our mission to keep pace with everything AWS releases. Second, it’s how our team likes to unwind after a busy year. I know, kind of weird, but hey it’s how we make sure we’re providing the latest and greatest for our customers. Below we’ve written about some of our favorite sessions from AWS re:Invent 2021.

You may view the entire playlist on YouTube by following the link here.

Keynotes

Several of my colleagues have already written about the keynotes so I’ll briefly summarize everything here.

Ross wrote about Adam Selipsky’s and Peter DeSantis’ Keynotes late last year.

Adam’s Keynote is required viewing for all aspiring cloud folks, but Peter’s 2021 keynote was something special. Peter’s keynote talked about the years of research and innovation that allow AWS to operate at truly dazzling scales. You must not miss this talk.

Another colleague Mark wrote about Werner Vogel’s keynote.

Finally, our fearless leader JP wrote about Doug Yeum’s partner summit keynote.

That only leaves the Databases, Analytics, and Machine Learning keynote by Dr. Swami Sivasubramian which is definitely worth a watch.

Leadership Sessions

While all of the re:Invent leadership sessions are worth watching we’ve picked out the ones below as particularly interesting and insightful.

Driving innovation and insight with cloud data on AWS Storage – Mai-Lan Tomsen Bukovec

In this session, Mai-Lan walks through several customer journeys through AWS storage, mainly S3, but also talks about the new releases. Pinterest is a featured customer in this session.

 

Reinvent your business for the future with AWS Analytics – Rahul Pathak

 

Building on 15 years of compute innovation – Dave Brown

 

AWS Networking: Making all workloads possible – Dave Brown

I shared some notes on LinkedIn already but I’ll quickly summarize them here.

  • In the first five years of operation, AWS had four regions. In the next five years, they had 11. In the last five years, they had 25 regions. In the next n+1 years AWS expects to open 9 more regions. All of these regions are connected by AWS’s global backbone of 100GbE fiber comprising terrestrial and undersea transoceanic cables.
  • Nitro is a fundamental difference between AWS and other cloud providers, it lets AWS offload virtualization to a hardware layer and provide the instance’s entire capacity to customers.
  • Covid-19 caused a 400% increase in AWS networking throughput over a matter of days.
  • In 2021 AWS processes 11 trillion metrics per day for AWS Networking.
  • In 2021 50gbps baseline EC2 Outbound Networking and up to 800gbps for HPC instances. Direct Connect now supports 100gbps ports!
  • Coming in 2022, SRD on ENAs will provide drastic bandwidth improvements.
  • All traffic is encrypted over the wire. IAM is an application layer security envelope. Traffic sent between regions with TGW or VPC peering is encrypted by default. Encryption methods are quantum-safe, AES-256, and post-quantum key exchange algorithms. Even if someone were to record your traffic today they wouldn’t be able to crack it in 10+ years when quantum computing tools are more readily available.
  • AWS is making strides in IPv6 across all of its infrastructure.
  • AWS Local Zones are exploding in usage and popularity. NASDAQ built its own “local zone” with outposts. 5G is a promising growth area for edge computing and networking.

 

Containers on AWS: Everywhere and anywhere – Deepak Singh

It’s always incredible to hear from Deepak and even though he couldn’t be in front of a live audience this year it was still a fantastic session.

Migrations

Evolve existing apps to microservices using Migration Hub Refactor Spaces

Belinda Quick (AWS), Michael Sciscenti (AWS), Jonah Jones (AWS)

In this talk, Belinda Quick walks us through some of the stories and learnings from large-scale migration and modernizations that AWS customers have done. Belinda quickly covers leave and layer approaches as well as strangler-fig approaches to migrations as well as multi-account strategies. Next Michael Sciscenti walks through how Refactor Spaces can deploy an application proxy to combine API Gateway, NLB, Transit Gateway, and Resource Access Manager to incrementally route traffic between legacy and migrated applications. Finally, Jonah Jones closes with a real-world demo of Refactor Spaces. If you take a look at the screenshot from this talk you might see a familiar name as one of the launch partners!

 

Learn how MAP can help you achieve your business outcomes

Faraz Shafiq (AWS), Alon Radzi (Amdocs)

In this session, Faraz Shafiq tells us how to navigate the tension between business and technology goals by showing examples from companies like Expedia, Dow Jones, and Coca-Cola. Faraz talks about the motivations for migrations and how customers tend to evolve as they modernize. He points out that, on average, customers realize 31% cost savings over comparable infrastructure, 62% more efficient IT infrastructure teams, and a whopping 75% increase in agility in delivering new features. Next Alon Radzi walks through a real-world example of using MAP to help telecom providers migrate to AWS.

DevOps Revolution

Emily Freeman (AWS)

A new model for thinking about DevOps as concentric circles of responsibility. Just a heads-up that the audio in this video is somewhat choppy. Towards the end of this talk, Emily walks through two concrete examples that navigate the new model. Finally, Emily closes with a “hexagons are the bestagon” skill assessment visualization.

 

Incorporating continuous resilience in your development ecosystem

Curtis Rissi (AWS)

In this talk, Curtis starts by describing the cost of downtime and the way downtime grows in applications. He then walks through tools, services, and best practices for reducing the probability of failure. Among those recommendations are setting timeouts, retry backoffs, jitter, queue size limitations, rate limiting, load shedding, cellular architectures, shuffle sharding, immutable infrastructure, monitoring, and alerting. Curtis closes with a brief discussion of Chaos Engineering. Whew! A great talk with a whirlwind of advice.
