SpringOne is a conference organized by VMWare (earlier Pivotal) is the premier conference for developers and architects building cloud-native software. They have recently concluded SpringOne 2021 on September 1-2, 2021 covering broader areas such as beginner and advanced Spring framework, Architecture Patterns and Cloud-native Platforms. This article summarizes key takeaways from SpringOne 2021 developer conference.

#1 – Developer productivity & application platform is pivotal

Highlighted key focus areas to enable developer’s productivity using capabilities of application platform such as:

Additionally, highlights from The State of Spring 2021 report were shared primarily focused for developers and architects with respect to Spring framework usage.

#2 – Synergy and partnership is the key to success

  • Invited many customers to share their success stories such as:
    • Hyundai accelerated digital journey using Tanzu platform applying App Modernization, Microservices and DevSecOps
    • GAP shared their journey of creating seamless customer experience using VMWare Tanzu Application Service
    • CVS, Morgan Stanley, and the U.S. Army shared their learning as part of their move to the cloud using Spring and Tanzu platform
  • Solidfied partnership with Microsoft Azure, which provides Azure Spring Cloud (a fully managed service)
  • Azure launched Azure Spring Cloud Enterprise in the conference providing full support to the Spring ecosystem
  • Parternship with Solace, which provides event-mesh capabilities for an enterprise for developing event-driven architecture
  • Demonstratd VMWare Tanzu support for full lifecycle of production workload as shown below using tools such as:

#3 – Support for new patterns and current & future technology trends

  • Highlighted extensive support for RSocket messaging platform by Spring for reactive programming (see diagram below)
  • Shared examples of using modern techniques like Cloud Native Buildpacks for Docker image (e.g. Paketo)
  • Sprint’s support for native image with GraalVM for applications in need of lower latency, higher throughput, and better startup time
  • Shared hands-on examples such as Dive, which is a tool for exploring a docker image, layer contents, and discovering ways to shrink the size Docker images
  • Demonstrated live examples of Spring framework capabilities such as Spring Cloud Stream, which can handle all communication scenarios related to event-driven microservices such as:
    • Persistent Pub/Sub
    • Consumer Group
    • Stateful Partitioning Support
  • Demonstrated synergy with Kubernetes as a platform in conjuction with Spring Cloud, particularly in areas where they have overlap such as:
    • Using Spring Cloud Config Service to get data from Git & Config Map
    • Spring Cloud Kubernetes Discovery Server integrated with Kubernete API server
    • Config Watcher integrated with Kubernetes API Server
    • No explicit coupling with Kubernetes API Server with Spring Microservices running in PODs
