Make your (automatic) releasing to Maven Central from Travis (and not only) more reliable thanks to the explicit staging repository creation feature set implemented at the edge of 2018 and 2019. Background If you are only interested in getting information how to make your artifacts releasing more reliable from Travis, move forward to the another section. Automatic artifacts releasing (using ...

In this post I am going to continue the story of implementing a conversational UI for FlexDeploy on top of Oracle Digital Assistant andFn Project. Today I am going to move the serverless API working around my chatbot to the cloud, so the entire solution is working in the cloud: The API is implemented as a set of Fn functions ...

Deploying control plane components Once you’ve built and designed your control plane, you’ll want to decide exactly how its components get deployed. You have some choices here from co-locate control plane with the data plane all the way to centralize your control plane. There is a middle ground here as well: deploy some components co-located with the control plane and ...

Envoy is a very powerful piece of software and every day new use cases and new contributions are being proposed to the community. Although the core of Envoy is very stable, it’s built on a pluggable filter architecture so folks can write new codecs for different L7 protocols or add new functionality. At the moment, Envoy filter’s are written in ...

The SPRING INITIALIZR at https://start.spring.io has been around for a while and is the best way to bootstrap a new Spring Boot application. So far, there hasn’t been a similar way to bootstrap a new MicroProfile project even if the different vendors have provided starters for their implementations. But the wait is over! The MicroProfile Starter is currently in “Beta”, ...

Establishing your control-plane interaction points and API surface Once you’ve thought through what components might make up your control-plane architecture (see previous), you’ll want to consider exactly how your users will interact with the control plane and maybe even more importantly, who will your users be? To answer this you’ll have to decide what roles your Envoy-based infrastructure will play ...

Identify which components you need for your control plane As the spectrum of operating environments varies wildly, so too could the components needed to implement a control plane for Envoy. For example, at one extreme, if you have Envoy files statically generated at build time and shipped to your Envoy, you will need components like: Template engineData store / VCSPer-service ...

Envoy has become a popular networking component as of late. Matt Klein wrote a blog a couple years back talking about Envoy’s dynamic configuration API and how it has been part of the reason the adoption curve for Envoy has been up and to the right. He called the blog the “universal data plane API”. With so many other projects ...

Not too long ago, a reactive variant of the JDBC driver was released. Known as R2DBC. It allows data to be streamed asynchronously to any endpoints that have subscribed to it. Using a reactive driver like R2DBC together with Spring WebFlux allows you to write a full application that handles receiving and sending of data asynchronously. In this post, we ...
