Spring Cloud AWS 2.3 is now available

The following is a guest post from the maintainers of the Spring Cloud AWS project.

On behalf of the Spring Cloud AWS team and the community around Spring Cloud AWS, I am happy to share that we have just released Spring Spring Cloud AWS 2.3 - a version that is compatible with Spring Boot 2.4 and Spring Cloud 2020.0.

This release contains a new integration with Cognito and a bunch of small improvements, fixes, and changes that we believe will make working with Spring Cloud AWS more pleasurable.

I believe the most surprising change is that now you need to include a separate Spring Cloud AWS BOM in your pom.xml file:

Deploy Spring Boot applications by leveraging enterprise best practices – Azure Spring Cloud Reference Architecture

Deploy Spring Boot applications by leveraging enterprise best practices – Azure Spring Cloud Reference Architecture

Today, we’re excited to announce the availability of the Azure Spring Cloud Reference Architecture. You can get started by deploying the Azure Spring Cloud Reference Architecture to accelerate and secure Spring Boot applications in the cloud at scale using validated best practices.

Over the past year, we worked with many enterprise customers to learn about their scenarios including thoughts on scaling properly, security, deployment, and cost requirements. Many of these customers have thousands of Spring Boot applications running in on-premises data centers. As they migrate these applications to cloud, they need battle-tested architectures that instill confidence to meet the requirements set forth by their IT departments and/or regulatory bodies. In many customer environments, they also need to show direct mappings from architectures to industry-defined security controls and benchmarks. We thank these customers for the opportunity to work with them, and for helping us to build an Azure Spring Cloud Reference Architecture. Using this reference architecture, you can deploy and customize to meet your specific requirements and showcase pre-defined mappings to security controls and benchmarks.

Announcing Spring Native Beta!

Today, after one year and half of work, I am pleased to announce that we’re launching the beta release of Spring Native and its availability on start.spring.io!

In practice, that means that in addition to the regular Java Virtual Machine supported by Spring since its inception, we are adding beta support for compiling Spring applications to native images with GraalVM in order to provide a new way to deploy Spring applications. Java and Kotlin are supported.

Those native Spring applications can be deployed as a standalone executable (no JVM installation required) and offer interesting characteristics including almost instant startup (typically < 100ms), instant peak performance and lower memory consumption at the cost of longer build times and fewer runtime optimizations than the JVM.
