Hi, Spring fans! In this episode Josh Long (@starbuxman) talks to Dr. Kris De Volder, a longtime member of the Spring Tools team, about all the cool stuff he's worked on and is going to work on. And then we get knee deep into a discussion around building IDE integrations.

We believe in providing the most innovative cloud offerings at incredibly competitive prices. As we operate Azure Spring Apps, we continue to build efficiencies and economies of scale. We are passing those efficiencies to you.

Many customers have asked us to lower the size of the base unit to make it easier to get started and accommodate smaller projects.

Announcing Price and Base Unit Reduction

Effective September 1st, we are reducing the base unit of Azure Spring Apps Standard and Enterprise to 6 vCPUs and 12 GB of Memory. And reducing the overage prices for vCPU and Memory.

In this article, we look into writing a custom extension for Spring Cloud Gateway. Before we get started, let’s go over how Spring Cloud Gateway works:

1. First, a client makes a network request to the Gateway
2. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. For example, you can match on the path segment of the URL or the HTTP method of the request.
3. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. For example, you might want to add query parameters to your request
4. A proxy filter routes the request to the proxied service
5. The service executes and returns a response
6. The gateway receives the response and executes post-request logic on each filter before returning the response. For example…
