GridGain Nebula August 4 2025 Release Notes
What’s New in This Release
GridGain® Nebula is a cloud-native, fully-managed service for Apache® Ignite™ and GridGain® Platform. Nebula eliminates the complexity of configuring, provisioning, managing, optimizing and scaling Apache® Ignite™ and GridGain® in cloud or hybrid environments. You can spend less time managing platform instances and more time building high-performance, scalable applications.
The latest Nebula release, August 4 2025, introduces support for the latest version of GridGain 9, as well as extended support for DCR in GridGain 9.
