Spring Cloud Function is a new project with the following high-level goals:

• Promote the implementation of business logic via functions.
• Decouple the development lifecycle of business logic from any specific runtime target so that the same code can run as a web endpoint, a stream processor, or a task.
• Support a uniform programming model across serverless providers, as well as the ability to run standalone (locally or in a PaaS).
• Enable Spring Boot features (auto-configuration, dependency injection, metrics) on serverless providers.

Just as Spring has always promoted a plain old java object (POJO) based programming model, Spring Cloud Function promotes a programming model based on plain old functions. By that we mean the core interfaces defined in the java.util.function package: Function, Consumer, and Supplier…

Dear Spring Community,

Last month, Spring Session lead Rob Winch announced the release of Spring Session 2.0.0.M1 (notice the lack of MongoDB there?) In that post, he pared back Spring Session to officially supporting Redis, JDBC, and Hazelcast. No more MongoDB.

I’m here to announce that I’ve pick up the torch for Spring Session MongoDB. Managing both Spring Session and Spring Security (among other responsibilities), Rob couldn’t maintain high caliber support with too many data stores. Being a member of the Spring Data team, I felt better suited toward providing MongoDB support of Spring Session, so I reinstated it as a separate project…

Hi Spring fans! This week I'm in Redmond, hanging out with our friends and Pivotal partner Microsoft talking about Cloud Foundry on Microsoft Azure. As you may know, Microsoft's Azure IaaS platform is the #2 most widely used cloud and it's growing! It's got more datacenters than the other two cloud vendors in more regions (including in Germany and China!) and a huge raft of services that support both Windows and Linux operating systems. There's so much exciting stuff coming up including Azure Stack, which runs Azure on-premise, and the amazing integration between Azure and PCF. I'm looking…
