Native and eBPF-based Kubernetes Workload Profiling for Kubernetes Clusters

System observability is an essential part of identifying performance issues within your environment because it provides a comprehensive view of how your systems are operating at a glance. Typically, observability is achieved through the collection and analysis of metrics. These metrics, generated by your applications, are deliberately incorporated by developers into the source code to offer insights into the application’s internal processes.

Network observability in Kubernetes clusters for better security and faster troubleshooting

For DevOps and platform teams working with containers and Kubernetes, reducing downtime and improving security posture is crucial. A clear understanding of network topology, service interactions, and workload dependencies is required in cloud-native applications. This is essential for securing and optimizing the Kubernetes deployment and minimizing response time in the event of failure.

Modern Egress Gateway: Assign stable IPs to traffic leaving Kubernetes clusters

Whether an enterprise is migrating its legacy application to a cloud-native architecture or deploying a new cloud-native application, it will face the challenge of integrating with security tools such as firewalls that rely on a stable network identity for security configuration. This is due to the fact that cloud-native workloads aren’t guaranteed to have a fixed network identity.

Amazon EKS networking options

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.

The power of Kubevirt and Calico

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.

What is platform engineering and when should you invest in it?

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.

Calico VPP: Empowering High-Performance Kubernetes Networking with Userspace Packet Processing

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.

Optimizing for High Availability and Minimal Latency in Distributed Databases with Kubernetes and Calico Cluster Mesh

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.

DNS troubleshooting for Kubernetes applications with Calico DNS dashboards

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.
