5 Key Takeaways from AWS re:Invent 2021 for Cloud Engineers

Excited Intro

AWS re:Invent 2021 was a blast and a real treat for all cloud engineers worldwide. As we all gathered remotely to witness the latest innovations and updates in the cloud computing world, we were amazed by the sheer number of releases, keynotes, and demos on display.

In this article, we’ll take a look at 5 key takeaways from AWS re:Invent 2021 that all cloud engineers should know about. We’ll cover exciting new features, services, and tools that promise to revolutionize cloud computing and make our lives easier. So, let’s dig in!

Takeaway #1: Machine Learning at Scale with Amazon SageMaker

Amazon SageMaker is a popular machine learning platform from AWS that simplifies and accelerates the building, training, and deploying of ML models at scale. And with the latest updates from re:Invent 2021, SageMaker is now more powerful than ever before.

One standout feature is the new feature store, which allows model developers to store, share, and reuse ML features across different datasets and models. This helps reduce redundancy and improves collaboration between teams.

Another exciting addition is SageMaker Edge Manager, which makes it easier to deploy ML models on edge devices such as IoT devices, smartphones, and robotics. Edge Manager provides an end-to-end workflow for deploying and managing ML models on edge devices, making it easier for developers to build intelligent AI solutions.

Takeaway #2: DevOps Simplification with AWS CodeArtifact

AWS CodeArtifact is a fully managed artifact repository service that makes it easier for developers to securely store, publish, and share software packages. With the latest updates from re:Invent 2021, CodeArtifact is now even more valuable for cloud engineers.

One standout feature is the support for package signing, which helps ensure the integrity and authenticity of software packages. Developers can sign packages using their own cryptographic keys, and users can verify the signature before downloading and using the packages.

Another exciting addition is the support for Python packages, making it easier to manage Python dependencies in large codebases. CodeArtifact integrates with popular package managers such as pip and setuptools, and supports both public and private repositories.

Takeaway #3: Serverless Computing with AWS Lambda

AWS Lambda is a popular serverless computing platform from AWS that lets developers run code without provisioning or managing servers. And with the latest updates from re:Invent 2021, Lambda continues to push the boundaries of serverless computing.

One standout feature is the support for container images, which allows developers to run custom runtime environments alongside their code. This enables more flexibility in how applications are deployed and managed, and opens the door for new use cases.

Another exciting addition is the support for .NET 6, which provides a faster and more efficient runtime for .NET applications. Developers can now build and run .NET 6 applications on Lambda with ease, and take advantage of the latest features and performance improvements.

Takeaway #4: Infrastructure as Code with AWS CloudFormation

AWS CloudFormation is a popular infrastructure as code service from AWS that lets developers automate the creation and management of AWS resources. And with the latest updates from re:Invent 2021, CloudFormation is now even more powerful and flexible.

One standout feature is the introduction of resource targets, which allows developers to apply updates to specific resources in a CloudFormation stack, rather than updating the entire stack. This helps reduce downtime and improves the overall reliability of the system.

Another exciting addition is the support for the Open Policy Agent (OPA), which provides a declarative language for defining policies and enforcing them across CloudFormation templates. This helps ensure that infrastructure is deployed securely and in compliance with organizational policies.

Takeaway #5: Cloud Management at Scale with AWS Control Tower

AWS Control Tower is a popular service from AWS that provides a central hub for managing multiple AWS accounts and enforcing organizational policies. And with the latest updates from re:Invent 2021, Control Tower is now even more valuable for cloud engineers.

One standout feature is the integration with AWS Systems Manager, which provides a unified interface for managing resources across multiple accounts and regions. This helps simplify the management of large-scale cloud environments, and improves visibility and control.

Another exciting addition is the support for customizations and extensions, which allows organizations to tailor Control Tower to their specific needs and requirements. This enables them to enforce policies and governance frameworks that align with their unique business objectives and compliance requirements.


With these exciting updates and releases from AWS re:Invent 2021, cloud engineers have more powerful tools and services at their fingertips than ever before. Whether it’s machine learning, DevOps, serverless computing, infrastructure as code, or cloud management, AWS continues to innovate and push the boundaries of what’s possible in the cloud.

As we look ahead to the future of cloud computing and the next re:Invent event, one thing is certain: the possibilities are endless, and the sky is the limit. So, let’s continue to embrace these new technologies and build amazing things together!
