Buoyant Announces Automated Multi-Cluster Failover Capabilities in Linkerd

Buoyant, creator of the widely-used open source Linkerd service mesh and of the Buoyant Cloud managed Linkerd service, announced the release of the new automated failover functionality for multi-cluster Kubernetes deployments.

This new feature, introduced as a Kubernetes operator in recent Linkerd releases,  automatically redirects application traffic to alternate Kubernetes clusters in the event of failures or outages in the original cluster. This capability allows applications built on Kubernetes to maintain system availability to customers even in the event of application outages, a critical part of disaster recovery (DR) and high availability (HA) scenarios.

"Running multiple clusters across regions, zones, or clouds, is a necessary part of any highly available application architecture. Unfortunately, Kubernetes itself provides very little in the way of help," said William Morgan, CEO of Buoyant and one of the original creators of Linkerd. "Linkerd solves critical and immediate problems for Kubernetes adopters, not just by providing secure cross-cluster communication that's fully transparent to the application, but now, with the new failover operator, by providing fully automated recovery mechanisms that trigger in the event of application and cluster failures." 

Building on the existing reliability, observability, and security features of the service mesh, Linkerd's new failover capabilities provide a flexible framework with which Kubernetes adopters can address a variety of situations. For service- and cluster-related failures, IT teams have the ability to automatically reroute traffic to a replica of a service in another cluster, reroute cross-cluster traffic to a different cluster, automate the service failover within a single cluster, and more.

This news comes on the heels of the release of Linkerd 2.11, which introduced network policy features, and the addition of network policy management to Buoyant Cloud. The network policy features are designed to address a critical need for security-conscious organizations and enable users to easily enforce security rules around the types of network traffic allowed within a Kubernetes cluster. As a result of its focus on security, simplicity and performance, Linkerd adoption has skyrocketed 118% in the last year according to the Cloud Native Computing Foundation (CNCF) Annual Survey 2021.
