Starting from version 3.1.0 as part of the Spring Cloud 2021.0.0 (aka Jubilee) release train, Spring Cloud Gateway included support for gRPC and HTTP/2.

We will introduce the basic concepts behind gRPC and how to configure it with two examples:

• One that showcases how Spring Cloud Gateway can transparently re-route gRPC traffic without needing to know the proto definition and without having to modify our existing gRPC servers.

• Another that showcases how we can create a custom filter in Spring Cloud Gateway to transform a JSON payload to a gRPC message.

Secure communications end-to-end for Spring Boot apps - in a Zero Trust environment

Hi, Spring fans! Today, we are excited to announce the general availability of all the features to secure communications end-to-end for Spring Boot apps – in a Zero Trust environment. You can secure communications end-to-end or terminate transport level security at any communication point for Spring Boot apps.

While the full list of features, enhancements and bug fixes is available here, I’d like to call out few of them in this post and provide some details.

gRPC Support

In addition to an already existing support for invoking function via AWS Lambda, RSocket, Spring Cloud Stream etc., Spring Cloud Function now allows you to invoke function via gRPC. Two ways to benefit from it.

Spring Message

Given the wide adaption of Spring Messaging, one way of benefiting from gRPC support is by embracing Spring's Message. Spring Cloud Function provides GrpcSpringMessage schema modeled after Spring's Message. It is internally converted to Spring Message to benefit from all of the existing support for Spring Messaging…

Hi, Spring fans! I love the Azure Spring Cloud platform - jointly developed with the Spring team and Microsoft - and I'm not alone! So do its users! Check out this panel discussion moderated by Adib Sakali and Asir Selvasingh with Morgan Stanley, Bosch, and Digital Realty Trust.

Hi, Spring fans! Welcome to another installment of This Week in Spring! This last week's been nutty! Here in the US, we just celebrated the Thanksgiving holiday, and I am fat with turkey and pie, and lazy. But happy. I hope you're well fed and happy, too. Time's flying.
