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!

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…
