Nimbella is a pure serverless cloud that leverages the public cloud infrastructure and can be extended to private on-premise infrastructure. It is built on open standards, giving developers full control over their architecture and code, without vendor lock-in. Serverless computing today is nascent, and is lacking the abstractions, automation, and integrations that have proven necessary to accelerate the adoption of technology in new markets and application domains. Nimbella fills the technology gaps and unifies the programming experience around serverless to deliver a complete and integrated solution that works across clouds. It is designed from the ground up to address the needs of event-based applications, long running applications, stateful workloads, and more complex use cases that employ artificial intelligence and machine learning.
