Monoliths, Client-Server, three-tier application and then? This article describes what could be the 4th generation application model: client-serverless. It also introduces Jamstack and FaunaDB, 2 promising technologies in that next-gen architecture.

In this blog post, James Beswick provides meaningful information related to synchronous and asynchronous requests between a web frontend and a backend, and how to implement web notifications using MQTT websockets with AWS IOT.

A series of articles from Lee James Gilmore on lessons he learned from his experience on serverless. It goes from tooling to security, through architecture and many hints that every developer / architect would like to know when starting on serverless.

James Beswick provides load testing for the web application "Ask around me", he created in previous blog posts. If you plan to scale up with your API / microservices, look at it as it gives few examples of Artillery, an open-source tool for testing APIs.

We tend to say that it is not a good practice to invoke a lambda from another lambda as it strongly couples the two functions. But in this blog post from Yann Cui, you'll see there are cases when you can actually do this.

This article provides meaningful information on how to handle DDoS attacks in a serverless environment. The cloud itself provides some protection but you can / should obviously adopt some good practices.

It is rare to get news about Alibaba Cloud, so if you want to discover this platform and what they provide on the serverless side, have a look at this article. It describes how to setup and deploy a function with the serverless framework.

This article from Lumigo shows how to use AWS X-Ray to debug and trace your serverless applications. But X-Ray is not yet integrated with all AWS services (for example Step Functions or EventBridge) and thus we don't get the full map of our application. Lumigo, a 3rd party solution can provide this kind of feature.

In my previous newsletter, I talked about the AWS Solutions Constructs, that provide an easy way to deploy common architecture patterns using CDK. This blog post is using this new feature to deploy an API Gateway, integrated with Lambda that uses DynamoDB as a database and another lambda consuming DynamoDB Stream.

If you are building serverless solutions, you should definitely read the AWS Serverless Application Lens, a subpart of the Well-Architected Framework dedicated to serverless. If you prefer a summary, look at this article (a pretty long summary but that's worth it). This is a must read.

If you are dealing with relational databases, you know that it cannot scale indefinitely. Associated with a lambda function, your database can quickly fall because of thousands of simultaneous connections. RDS Proxy can help you achieve better resilience and scalability with your relational database. And it's now GA! Look also at this article from Matt Coulter that describes why it is important and also provides some CDK code to deploy it.
