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.

Integrating Prometheus AlertManager with PagerDuty in Calico

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.

How to observe and troubleshoot microservices connectivity in Amazon EKS

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.

What you can't do with Kubernetes network policies (unless you use Calico): Policies to all namespaces or pods

Continuing from my previous blog on the series, What you can’t do with Kubernetes network policies (unless you use Calico), this post will be focusing on use case number five — Default policies which are applied to all namespaces or pods.

What is a Kubernetes cluster mesh and what are the benefits?

Kubernetes is an excellent solution for building a flexible and scalable infrastructure to run dynamic workloads. However, as our cluster expands, we might face the inevitable situation of scaling and managing multiple clusters concurrently. This notion can introduce a lot of complexity for our day-to-day workload maintenance and adds difficulty to keep all our policies and services up to date in all environments.

New report: The state of Calico Open Source 2023

We are excited to announce the publication of our 2023 State of Calico Open Source, Usage & Adoption report! The report compiles survey results from more than 1,200 Calico Open Source users from around the world, who are actively using Calico in their container and Kubernetes environments. It sheds light on how they are using Calico across various environments, while also highlighting different aspects of Calico’s adoption in terms of platforms, data planes, and policies.
