1.0.0

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.

Please read the official blog post for more information.

Notable Features:

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.

Other ➕

• Kuma 1.0 ships with a new GUI!
• Added over 30+ new charts available out of the box in Grafana to capture the behavior of the CP at scale. Kuma now provides over 65+ charts out of the box.
• Added support for AWS ECS and Fargate deployments.
• Upgraded to latest Envoy 1.16.0.

We strongly suggest to upgrade to this new version while paying attention to a few breaking changes that 0.7 introduces.

Notable Features:

• A new Zone resource to add remote CPs without restarting the global CP
• An upgraded ProxyTemplate policy to enable better fine-tuning of the underlying Envoy filters
• Support for StatefulSets to run a service mesh across every service like RabbitMQ and Cassandra

Notable Improvements:

• New Hybrid Universal mode to build distributed service meshes

0.3.2

A new Kuma release that brings in many highly-requested features:

• support for ingress traffic into the service mesh - it is now possible to re-use
  existing, feature-rich API Gateway solutions at the front doors of
  your service mesh.
  E.g., check out our instructions how to leverage Kuma and Kong together. Or, if you're a hands-on kind of person, play with our demos for kubernetes and universal.
• access to Prometheus metrics collected by individual dataplanes (Envoys) -
  as a user, you only need to enable Prometheus metrics as part of your Mesh policy,
  and that's it - every dataplane (Envoy) will automatically make its metrics available for scraping. Read more about it in the docs.
• native integration with Prometheus auto-discovery - be it kubernetes or universal (😮), Prometheus will automatically find all dataplanes in your mesh and scrape metrics out of them. Sounds interesting? See our docs and play with our demos for kubernetes and universal.
• brand new Kuma GUI - following the very first preview release, Kuma GUI have been significantly overhauled to include more features, like support for every Kuma policy. Read more about it in the docs, see it live as part of our demos for kubernetes and universal.
