Calico 3.28 now has enabled VXLAN checksum offload by default for environments with the kernel version of 5.8 or above. In the past, offloading was disabled due to kernel bugs. Please keep in mind, if you are upgrading to 3.28 this change will take effect after node restarts.

When setting up a Kubernetes environment with Amazon Elastic Kubernetes Service (EKS), it is crucial to understand your available networking options. EKS offers a range of networking choices that allow you to build a highly available and scalable cloud environment for your workloads. In this blog post, we will explore the networking and policy enforcement options provided by AWS for Amazon EKS.

Virtualization is a powerful technology that allows businesses to run multiple operating systems and applications on a single physical server. Kubevirt is an open-source tool that makes it easy to deploy and manage virtual machines (VMs) on Kubernetes and Calico is an open-source networking and security tool that provides easy yet robust networking and security for Kubernetes workloads.

As application platforms grow larger, the idea of DevOps teams where developers support the software development lifecycle, but also manage infrastructure and the platform, is beginning to reach the limits of what these teams can support. Rather than taking their best application developers and making them work on infrastructure problems, more organizations are coming to the conclusion that a centralized platform team specialized in that area is a better use of their developers’ skill sets.

This is a guest post authored by Nathan Skrzypczak, R&D Engineer at Cisco. Calico VPP, the latest addition to Calico’s suite of pluggable data planes, revolutionizes Kubernetes networking by enabling transparent user-space packet processing. With features such as service load balancing, encapsulation, policy enforcement, and encryption, Calico VPP brings the performance, flexibility, and observability of VPP to Kubernetes networking.

Efficient connectivity for stateful workloads such as databases across multiple Kubernetes clusters is crucial for effective multi-cluster deployments. The challenge lies in providing seamless communication between services deployed across these clusters. Calico Cluster mesh enhances Kubernetes’ native service discovery, allowing it to function across multiple Kubernetes clusters.

Within Kubernetes, the Domain Name System (DNS) plays a pivotal role in facilitating service discovery, allowing pods to effectively locate and interact with other services within the cluster. For organizations transitioning their workloads to Kubernetes, establishing connectivity with services external to the cluster is equally important.

In the fast-paced world of Kubernetes, guaranteeing optimal performance and reliability of underlying infrastructure is crucial, such as container and Kubernetes networking. One key aspect of achieving this is by effectively managing alerts and notifications. This blog post emphasizes the significance of configuring alerts in a Kubernetes environment, particularly for Calico Enterprise and Cloud, which provides Kubernetes workload networking, security, and observability.

In the complex landscape of microservices within Amazon Elastic Kubernetes Service (EKS), maintaining seamless connectivity within microservices is paramount for ensuring optimal performance and reliability. As organizations increasingly embrace microservices architecture, understanding how to observe and troubleshoot microservices connectivity issues in Amazon EKS becomes a critical skill set.

Calico v3.27 is out 🎉 and there are a lot of new features, updates, and improvements that are packed into this release. Here is a breakdown of the most important changes.
