The Spring Observability Team has been working on adding observability support for Spring Applications for quite some time, and we are pleased to inform you that this feature will be generally available with Spring Framework 6 and Spring Boot 3!

What is observability? In our understanding, it is "how well you can understand the internals of your system by examining its outputs". We believe that the interconnection between metrics, logging, and distributed tracing gives you the ability to reason about the state of your system in order to debug exceptions and latency in your applications. You can watch more about what we think observability is in this episode of Enlightning with Jonatan Ivanov…

Spring Cloud Stream

• Both Kafka and RabbitMQ binders for Spring Cloud Stream have been migrated as part of the core Spring Cloud Stream repository. With this change, Spring Cloud Stream now follows a mono-repo approach where all the framework-related codebase for Spring Cloud Stream is now part of a single repository. See more details here for the Kafka binder and here for the RabbitMQ binder. We recommend filing new feature requests and bug reports for Kafka and RabbitMQ binders in the core repository.
• Introduced initial support for a new reactive Kafka binder based on Reactor Kafka. This support contains consumer and producer bindings using Reactor Kafka behind the scenes. See this issue…

Spring Cloud Pipelines is a GitHub project that tries to solve the following problems:

• Creation of a common deployment pipeline

• Propagation of good testing and deployment practices

• Reducing the time required to deploy a feature to production.

The first commit took place on 31-08-2016. Since then, we have gotten a lot of feedback from the community related to the suggested deployment pipeline and its concrete visualisations. Over those two years, the most important features we have managed to build are:

• Opinionated deployment pipeline setup

• Scripts for the pipeline, to verify backward compatibility of your project and allow zero-downtime deployment

• Support for PHP, .NET, NodeJS, and JVM (Maven & Gradle) projects

• Deployment option for Cloud Foundry

• Deployment option for Kubernetes

• Deployment option via Ansible

• Pipeline visualisation in Jenkins by using Jenkins Job DSL

• Pipeline visualisation in Jenkins by using Jenkinsfile

• Pipeline visualisation in Concourse

On behalf of the Spring Cloud team, it is my pleasure to announce a new milestone release of Spring Cloud Pipelines - 1.0.0.M8.

What’s new?

This release adds a lot of new features and quality and testing improvements. As for main features, we’ve added support for a project with multiple modules, and for mono-repos (projects with standalone application sources in it). As for quality and testing, we’re approaching 200 Bash tests (we’ve written missing tests for the Concourse pipeline). We’ve started publishing the project’s sources as a downloadable artifact. That way instead of cloning the repo or downloading the ~25mb archive, you can fetch around 150kb of sources. The docs for 1.0.0.M8…
