Deployment options now include serverless, with Akka running the user’s apps in Akka’s cloud, and “bring your own cloud,” with users supplying their own AWS, Microsoft Azure, or Google Cloud cloud instances and Akka bringing the control plane, a cost profile, and managed infrastructure services. In early-2025, the company plans to roll out a self-hosted option for running Akka apps wherever desired, either on-premises or in private or a hybrid cloud.
For cloud deployments, Akka has focused on providing more flexibility regarding how an application is deployed and replicated, supporting single-region/pinned, multi-region/read-replicated, and multi-region/write-replicated topologies. Innovations in Akka 3 include an application runtime with multi-master replication, where each service instance runs in multiple locations, and a PaaS that migrates across hyperscalers, with operations able to stretch an application across multiple clouds and migrate an app from one cloud to another with no downtime or disruption.
Akka enables development of applications that are primarily event-driven. The platform provides libraries, components, sandboxes, build packs, and a cloud runtime, the company said.
