Hi— this is Kisan from The Cloud Handbook. Every week, I send a curated roundup of the useful and practical resources from across the cloud community that include what I am reading, Ideas, hands-on, books, and updates from around the community.
Let’s get started with re:Invent announcements.
Here are some of the announcements on re:Invent 2025 so far.
Introducing AWS Lambda Managed Instances: Serverless simplicity with EC2 flexibility
AWS Lambda Managed Instances, a new capability you can use to run AWS Lambda functions on your Amazon Elastic Compute Cloud (Amazon EC2) compute while maintaining serverless operational simplicity. This enhancement addresses a key customer need: accessing specialized compute options and optimizing costs for steady-state workloads without sacrificing the serverless development experience you know and love.
Introducing AWS Transform custom: Crush tech debt with AI-powered code modernization
AWS Transform custom, a new agent that fundamentally changes how organizations approach modernization at scale. This intelligent agent combines pre-built transformations for Java, Node.js, and Python upgrades with the ability to define custom transformations. By learning specific transformation patterns and automating them across entire codebases, customers using AWS Transform custom have achieved up to 80% reduction in execution time in many cases, freeing developers to focus on innovation.
You can define transformations using your documentation, natural language descriptions, and code samples. The service then applies these specific patterns consistently across hundreds or thousands of repositories, improving its effectiveness through both explicit feedback and implicit signals like developers’ manual fixes within your transformation projects.
Announcing Amazon EKS Capabilities for workload orchestration and cloud resource management
Amazon Elastic Kubernetes Service (Amazon EKS) Capabilities, an extensible set of Kubernetes-native solutions that streamline workload orchestration, Amazon Web Services (AWS) cloud resource management, and Kubernetes resource composition and orchestration. These fully managed, integrated platform capabilities include open source Kubernetes solutions that many customers are using today, such as Argo CD, AWS Controllers for Kubernetes, and Kube Resource Orchestrator.
Introducing Amazon Route 53 Global Resolver for secure anycast DNS resolution (preview)
Amazon Route 53 Global Resolver, a new Amazon Route 53 service that provides secure and reliable DNS resolution globally for queries from anywhere (preview). You can use Global Resolver to resolve DNS queries to public domains on the internet and private domains associated with Route 53 private hosted zones.
AWS Clean Rooms launches privacy-enhancing dataset generation for ML model training
Train ML models on sensitive collaborative data by generating synthetic datasets that preserve statistical patterns while protecting individual privacy through configurable noise levels and protection against re-identification.
This week, I am experimenting with AWS Deadline Cloud. Weird name, right? I am working with a client who uses AWS to render heavy media. For this, AWS Deadline Cloud is a perfect solution. Here are some resources I have been using:
My friend Tobias compiled the top 15 AWS pre:Invent announcements.

I am a big fan of Serverless. This week, I have curated these two workshops just for you. Get your hands dirty. And let me know if you have any questions.
Building applications with a serverless mindset
This workshop is intended for developers and architects that are building Serverless applications and want to learn how to use direct integrations. Once you complete the workshop, you will be familiar with direct integrations and how to use them.
The Serverlesspresso workshop!
In this workshop, you will build the serverless backend that supports Serverlesspresso. You will then test your application using provided front-end applications.
A terminal-based AWS cost and resource dashboard built with Python and the Rich library. It provides an overview of AWS spend by account, service-level breakdowns, budget tracking, and EC2 instance summaries.
Serverless Development on AWS: Building Enterprise-Scale Serverless Solutions
The adoption of serverless is on the rise, but until now, little guidance has been available for development teams that want to apply this technology on AWS. This definitive guide is packed with architectural, security, and data best practices and patterns for architects and engineers who want to build reliable enterprise-scale serverless solutions.
If you found something worth sharing, reply to this email. I might feature it next time. Any feedback and contributions are appreciated.
