Today is a big day for Kuma! Kuma 1.0 is now generally available with over 70 features and improvements ready to use and deploy in production to create modern distributed service meshes for every application running on multiple clusters, clouds, including Kubernetes and VM-based workloads.
Before we unpack this release, a big thank you to the community and to the users that have helped releasing this major version of Kuma with their contributions and feedback.
Don’t forget to follow Kuma on GitHub and ask any questions on the community Slack.
Kuma 1.0 ships with 65+ charts out of the box for Grafana, although you can collect data from any other system too with the TrafficLog and TrafficMetrics policies.
Notable Improvements in 1.0
This new version comes with significant new capabilities and improvements around the following areas:
Multi-Zone 🌎
- Simplified multi-zone deployment with auto generation of “Zone” resources.
- Locality aware load-balancing to reduce multi-zone latency and reduce egress costs.
- Automatic synchronization of ingress data plane proxies to global CP via the new “Ingress” DP type.
Services & Policies 🚀
- Added support for explicit external services.
- Added support for a new “Service” resource that groups multiple data plane proxies per “kuma.io/service”.
- Added support for the Kafka protocol.
- Configurable pass-through control capabilities in a “Mesh” resource.
Performance 📊
- Battle tested in production in mission critical SLA-enforced enterprise environments.
- Significant overall performance improvements (~5x) when running tens of thousands of services in Kuma.
- Improvements in internal caching of resources to better support high data plane proxy loads.Improved overall scalability of the CLI and the GUI when running with a large amount of resources.
Security 🔒
- A new flow for securing data plane proxies with the control plane and locking down the communication between them.
- A new flow for starting data plane proxies and connecting them to the control plane that works better in non-K8s containerized environments.
- Added support for Kubernetes probes.
- Improved readiness checks for sidecar proxy in Kubernetes.
