AWS re:Invent 2021 – Hot Takes from The Serverless Edge

Reading Time: 4 minutes

AWS re:Invent 2021 is almost upon us. Every year the event disrupts the market, automatically makes your system more efficient (if you build things correctly) and puts fear into non-Amazon technical people as they realize how quickly public cloud really moves. It’s also in Las Vegas, which is the perfect place to spend four days indoors with no sunlight, no fun and endless hours in a meeting, talking and walking. Here are some hot takes from The Serverless Edge.

These are not strictly predictions. Think of them as half wishlist items and half “things to watch out for” at AWS re:Invent 2021. Usually, when new products are launched, the talks appear in the schedule that day, so it’s always important to check right after the keynote (or even during). Virtual attendees will be fine, there’s no capacity issues in the virtual talks. For physical attendees, capacity is a nightmare – it’s practically impossible to get into a hot talk at AWS re:Invent (in that case, best to watch it the week after as all talks appear online pretty quickly).


We have been on the sustainable technology trip for a few years now. Quite simply, if you build modern (serverless) applications on Cloud (AWS, GCP, Azure), then we believe this is the most sustainable approach for carbon burn. Is this the year at AWS re:Invent 2021, that AWS will provide sustainability guidance, telemetry and data to prove this?

Developer Experience

A big talking point among developers, there is a “Cloud Native” developer experience that AWS need to improve. Azure and GitHub have a very compelling offering – AWS have many of the same building blocks, but the general Developer Experience requires a boost. What announcements will we see?

Removing the foot gun option – The unexpected cloud bill can be terrifying and is very off-putting to anyone getting started in the cloud. Will this be the year where we see a capped account that CANNOT exceed a pre-defined amount?


With products like EventBridge and StepFunctions, it’s getting easier to create complex integrations with a serverless mindset. This is a way to create very complex business process flows that are well-architected and serverless-first. Also, these solutions will be cost-effective and quicker to build. What can AWS layer on top of this to increase adoption in an already growing area?

The split of modern applications

We see AWS bring in the container crew by providing options and control to run in the AWS environment. We also see a move the other way with Functionless services (serverless without Lambda – Managed Services talking directly to other managed services). AWS are clever and will promote both – customer obsession. We expect to see more innovation in both these areas.

ML Everywhere

In 2019 we saw things like ML used for coding and security. Expect this to continue as AWS disrupts itself with ML. The ML offering itself will continue to be refined, but “ML as a capability” will continue as a trend.

Security and Governance automation

Making the Cloud easier and more secure is a day one activity. Expect AWS to continue to enable customers, both old and new, by making it easier to secure and govern those precious workloads. With Azure’s recent security issues, will AWS extend its security lead?

Chaos Built in

We love seeing the evolution of Continuous Resiliency capabilities in AWS and the growth of the Fault Injection Simulator (FIS) service. We wonder if Chaos capabilities will be built into the more AWS services, making running experiments even easier.

Improving the Cloud Narrative

Even though re:Invent is a technology conference, there will be many professionals that are not engineers – CFO, Sales, Product, Design, Public Sector, retail, you name it. AWS need to enable companies that are not technology companies to join the cloud revolution and innovate. We see seeds planted in “Digital Innovation” programs and “Art of the Possible”, a less-tech heavy narrative will start bringing the cloud into the mainstream for business people of every domain.

The Serverless Edge will be at re:Invent in 2021, so look out for posts, photos and scoops. We are really looking forward to the keynotes this year and hopefully, there will be some synergy to what we like to talk about and our Value Flywheel!
