Weekly update 15

Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.

Hi, welcome to another weekly update!

MEAP update for Production-Ready Serverless

We have released 3 new videos on my video course Production-Ready Serverless!

I have recorded the last chapter on canary deployments, which should be with you shortly. Remember, whilst the course is still in the MEAP, you can get 40% off the face price using the code ytcui.

Welcome CloudZero as our sponsor for November!

It is my pleasure to welcome CloudZero as sponsor for this blog! Here’s a message from CloudZero to explain what they’re building and their vision for the future of Serverless.
CloudZero’s platform provides Finance and DevOps teams (FinDevOps) with rapid feedback of operational cost and application performance in AWS, enabling teams to work together in ways not possible before, focusing on cost as an operational metric. 


Our platform automatically analyzes your cloud environment and visualizes the state and cost of your cloud’s operating performance in real-time. With cost as an operational metric CloudZero can visualize your infrastructure within the context of cost. 


At CloudZero we believe that the new world is where the cloud is the computer and the cloud provider is the OS. We also believe that cloud computing is more than just FaaS (Functions as a Service), cloud computing encompasses a broad spectrum of services. We support 100% serverless applications as well as applications that span the technology spectrum from EC2 to platform services to Lambda. CloudZero supports your systems of today and tomorrow, regardless of where you are on the spectrum. 


We will be at AWS re:Invent 2018 – visit us at Booth #715!


It’s been a busy two weeks – I joined Jeremy Daly and Corey Quinn for Epsagon’s launch webinar, and spoke at CodeMesh, Serverless Computing London and BuildStuff.

AWS Announcements

Lambda doubles payload size limit for async invocations from 128MB to 256MB.

API Gateway introduced tiered pricing so the cost per million requests drops as your usage goes up.

You can now set account-level policy to block public access to S3 objects. This is useful when you have a dedicated AWS account for your data lake (a recommended practice), where you can guard against accidental data exposure at the account level.

AWS announced a new Milan region for 2020.

Secrets Manager has improved the console experience, letting you tag secrets, etc. Useful, but ultimately you probably shouldn’t be using the console to provision secrets IMHO, especially as you can now use CloudFormation to provision secrets in Secrets Manager.

GuardDuty adds three new threat detections, including detection of EC2 instances suspected to doing bitcoin mining!

SNS adds server-side encryption support! Yay!!

There is a new feature for CloudFormation to detect when resource configurations have drifted from the CF template – often result of manual changes to the environment.

Aurora Serverless is available in nine new regions including many regions in Asia, as well as London and Frankfurt.

EC2 has added a range of AMD-powered instance types.

You can now configure AWS Cost and Usage reports to be sent directly to a S3 bucket so you can easily query them (you’ll still need an AWS Glue crawler to crawl the bucket) with Athena.

It’s now easier to do cross-region deployment with CodePipeline.

Hi, I’m Yan. I’m an AWS Serverless Hero and the author of Production-Ready Serverless.

I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.

Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.

Hire me.

Check out my new podcast Real-World Serverless where I talk with engineers who are building amazing things with serverless technologies and discuss the real-world use cases and challenges they face. If you’re interested in what people are actually doing with serverless and what it’s really like to be working with serverless day-to-day, then this is the podcast for you.

Check out my new course, Learn you some Lambda best practice for great good! In this course, you will learn best practices for working with AWS Lambda in terms of performance, cost, security, scalability, resilience and observability. We will also cover latest features from re:Invent 2019 such as Provisioned Concurrency and Lambda Destinations. Enrol now and start learning!

Check out my video course, Complete Guide to AWS Step Functions. In this course, we’ll cover everything you need to know to use AWS Step Functions service effectively. There is something for everyone from beginners to more advanced users looking for design patterns and best practices. Enrol now and start learning!
