Serverless Transformation #31: Application Design

By Serverless Transformation - by aleios • Issue #31 • View online

Welcome to Issue #31 of the Serverless Transformation Newsletter! Last week, we looked at how you could roll your own Zoom with the Amazon Chime SDK, Event-Driven Architectures, and highlights from AWS re:Invent part two. This week, we’re looking at the best way to migrate a legacy system to Serverless, Serverless Application Design, and Service Quotas.

Top Five

Minimum Viable Migrations — bringing agility to Cloud Modernization

Often Serverless applications are built to replace legacy systems that are struggling to scale. However, this can require a large investment and take a long time to reach feature parity.

In this article, Ben Ellerby shows you how to get value out of your migration straight away by avoiding a ‘Big Bang’ release and instead gradually migrating your system.

James Beswick’s Operating Lambda series has become a staple of our newsletter. Having finished his trilogy on Event-Driven Architectures, James has now started looking at the topic of Application Design.

Follow-up to “Skip Lambda…” — Why You Shouldn’t Skip It

You might remember in issue 25 we included an article by Chris Bailey on how to use VTL and API Gateway to save to DynamoDB without a lambda. It is very similar to the way VTL is used with AppSync, and it’s a simpler, more efficient, and cheaper way to get data into DynamoDB.

However, in this follow up article, Chris explains why this shouldn’t be your new default choice. His two main reasons are to provide data validation and security.
