Practical Multi-Cluster: DR, Cloud Migration, Progressive Delivery, & More We talk a lot about multi-cluster for high availability and performance, but there are actually a lot of other things you can do with multi-cluster. Used properly, multi-cluster brings you into a world where you can treat whole clusters like cattle: interchangeable building blocks that are easily replaced whenever it’s useful. Multi-cluster can simplify disaster recovery, migration between cloud providers, progressive delivery, and more. Join us to see how!

We're happy to announce the release of Buoyant Enterprise for Linkerd 2.15.5. This latest stable release fixes a potential panic in the destination controller, and includes a fix for CVE-2024-40632, a low criticality CVE in Linkerd. BEL 2.15.5 is our fifth stable release in the Linkerd 2.15 line. Like every BEL release, it has undergone rigorous production testing across a variety of platforms including EKS, AKS, GKE, and OpenShift, as well as running in production at Buoyant itself.

New blog post by Buoyant CEO William Morgan: The Trouble with Topology Aware Routing, Part II: Introducing High Availability, Zone-Aware Load Balancing. Part I of this post covered Topology Aware Routing (TAR), a Kubernetes feature that restricts traffic within an availability zone from crossing to other zones, cutting cloud spend, sometimes dramatically. Cloud providers charge for traffic across zones, and since Kubernetes balances traffic as evenly as possible, high-traffic clusters can rack up cross-zone traffic charges very quickly. By restricting traffic from crossing zone boundaries, TAR can cut this aspect of cloud spend. But TAR is not without drawbacks: it can lead to worse overall system reliability.  If using TAR can reduce reliability, what does this mean for Kubernetes adopters who want the best of both worlds—minimal cloud costs and maximal reliability? This blog post focuses on that. #linkerd #servicemesh #cloudnative

Up next on Buoyant’s Service Mesh Academy: Practical Multi-Cluster: Disaster Recovery, Cloud Migration, Progressive Delivery, and More.

The full recording of last week's Service Mesh Academy workshop is live! Watch IPv6 with Linkerd. Future-Proofing your Network below. The wait is over! Users asked for it, and IPv6 support in Linkerd is finally here. Almost everything on the Internet today was originally designed for a world using networking rooting in version 4 of the Internet Protocol (IPv4) — even though we ran out of IPv4 addresses years ago! IPv6 deals with this situation by providing for dramatically more addresses, simpler autoconfiguration, better security, and easier access to global routing. In this hands-on workshop, we show you how Linkerd can be a part of this new world! #linkerd #servicemesh #opensource #cloudnative
