Attendee guide: Serverless

This guide highlights interesting sessions about serverless.

AWS Serverless Hero

Danielle Heberling

AWS Serverless Hero and Senior Software Engineer at Ensomata

 

The word “serverless” means a lot of different things to different folks. To me, serverless is a mindset that includes choosing tools that offload undifferentiated heavy lifting onto third-party providers (like AWS) so you can focus on providing customer value.

 

AWS offers lots of great managed services that are on the serverless spectrum, and I’m excited to share some AWS re:Invent sessions that highlight some of them. Whether you’re new to serverless or have shipped lots of serverless production workloads, I encourage you to check out these sessions.

Breakout sessions

COM305 | Demystifying and mitigating AWS Lambda cold starts

I have not had many issues related to cold starts in personal and professional projects; however, cold starts are often cited as a reason why teams do not adopt serverless. Come hear about the AWS Lambda lifecycle and how you can apply that knowledge to minimize your cold starts.

SVS401 | Best practices for serverless developers

Despite working with AWS serverless since 2018, I always learn a lot from Chris Munns and Julian Wood. They do a great job of explaining complex topics in a digestible manner with practical real-life examples.

API303 | Navigating the journey to serverless event-driven architecture

I’m a big fan of event-driven architecture (EDA), mostly because once you get over the initial learning hurdles you’ll realize that it feels like a much more natural way to have an application behave. This session looks like a nice overview of EDA with some patterns and tips as you get started.

API401 | Advanced workflow patterns and business processes

AWS Step Functions is a very underrated service. With so many different options, it can sometimes be overwhelming to choose how to best set up your Step Functions workflow. This session covers architectural best practices when using Step Functions with real production scenarios. I’m sure we’ll learn a lot.

Chalk talks

SVS310 | Automated testing for serverless and event-driven architectures

A lot of system flows are asynchronous with serverless, so it can be challenging to know how to test something. This chalk talk looks like it’ll offer some nice blueprints to get started toward creating a robust test suite for your serverless and event-driven workloads.

API207 | Messaging at scale: How to decide which service to use

Choices are great, but can also cause confusion about when it’s best to use each option. This chalk talk offers a nice explanation of just that with various managed messaging services, including Amazon SQS, Amazon SNS, and Amazon Kinesis.

API305 | Building resilience in decoupled applications with dead-letter queues

Dr. Werner Vogels once famously said, “Everything fails, all the time.” Decoupled and event-driven architectures are great, but they too can fail. When that happens, a dead-letter queue (DLQ) can be helpful. This chalk talk provides a nice overview of how to utilize DLQs to recover from failure.

SVS203 | Thinking serverless

Beyond all the hype and buzzwords, serverless is really just a mindset. This chalk talk allows us to take time to reflect on why a serverless mindset can help us focus more on what matters—our customers.

Learn more

API308 | Accelerating event-driven architecture with domain-driven design

A lot of times it’s easy to get started, but down the line, we run into many bumps. This chalk talk explains how we can use domain-driven design principles to build robust event-driven cloud architectures that scale.

Keynotes

KEY005 | Dr. Werner Vogels Keynote

Not always 100% serverless related, but this is the big keynote that you don’t want to miss. Last year, Dr. Werner Vogels wore a lambda shirt with the theme of being asynchronous, which resulted in lots of exciting serverless announcements, such as AWS Application Composer.

Key001 | Monday Night Live with Peter DeSantis

This keynote is also not 100% serverless, but “there are servers in serverless.” This keynote often goes deep into detail about the infrastructure that powers many AWS serverless services. It’s worth a watch to learn something new and to have a deeper respect for all of the work that goes into building and maintaining these managed services.

Workshop

API201 | Serverlesspresso: Building event-driven applications from the start

I went through this workshop on my own and had a blast learning about AWS Step Functions and Amazon EventBridge to build a real-world application for a coffee shop. It’s probably even better when attending live at AWS re:Invent.

Other Recommendations

If you’re going to AWS re:Invent in person, I recommend focusing on attending workshops and chalk talks since those will not be recorded and put on the internet to watch later. Wear comfortable shoes since you’ll be on your feet a lot, and be sure to drink lots of water because it takes place in a desert. Also, re:Play, the final conference event, is like a fun party with live music. It can get loud, so pack some earplugs. Anyway, I hope you enjoyed the guide and hope to see you at re:Invent on the hallway track.
