May 2025 Summaries

Replicated's Deep Dive Series explores the decision-making process for deploying Kubernetes-based applications in either an existing customer-managed cluster or using Replicated's Embedded Cluster. This architectural choice can affect onboarding, supportability, maintenance, and scalability. The session, featuring insights from Chuck D'Antonio, Amber Alston, and Alex Parker, emphasizes that there is no one-size-fits-all solution, as the decision depends on factors such as customer maturity, DevOps capabilities, and security requirements. Misconceptions about the Embedded Cluster's reliability are addressed, highlighting its robustness and suitability for both proof-of-concept and production environments. Replicated's Embedded Cluster, built on K0s, offers ease of deployment and maintenance but may not suit customers with sophisticated existing Kubernetes environments, such as those in finance or healthcare. The ultimate goal is a customer-centric deployment strategy that accommodates both models, allowing vendors to meet diverse customer needs while reducing friction throughout the customer lifecycle.

Multi-node and high availability support in Embedded Cluster is now generally available with the release of version 2.4.0, making it easier for software vendors to deliver Kubernetes applications to customer-managed environments without requiring Kubernetes expertise. The update includes an Admin Console that simplifies node addition, reducing setup time and bandwidth usage for large clusters. High availability is achieved through the replication of data and services across nodes, and automation of multi-node installations is supported by a new command, although node roles remain in beta. Vendors can customize customer deployment experiences by enabling or disabling multi-node support, streamlining installations according to customer needs. This release aims to simplify Kubernetes for application vendors and end-users, providing scalable and production-grade environments with minimal effort.
