Build and secure multi-cluster CockroachDB using the Calico clustermesh: A step-by-step guide

With the rapid adoption of Kubernetes in organizations and the push to standardize the orchestration of resources with this approach, databases are now also being deployed into Kubernetes. Historically, persistent workloads like databases were not recommended for their deployment into Kuberntes as it was complex to manage how data would be stored. This was a result of Kubertnes originally being designed for non persistent microservice architectures.

Audit and Compliance with Calico

In this blog post, I will be talking about audit and compliance and how to implement it with Calico. Most IT organizations are asked to meet some standard of compliance, whether internal or industry-specific. However organizations are not always provided with the guidance to implement it. Furthermore, when guidance has been provided, it is usually applicable to a more traditional and static environment and doesn’t address the dynamic nature of Kubernetes.

Container Security Fundamentals - Linux Namespaces (Part 2): The PID Namespace

In this video we continue our examination of Linux namespaces by looking at some details of how the PID namespace can be used to isolate a container’s view of processes running on the host, and how this feature can be used for troubleshooting container problems. To learn more read our blog on Datadog’s Security Labs site.

Cloud Defense in Depth: Lessons from the Kinsing Malware

In the face of persistent data breaches and escalating cyber threats, organizations are compelled to prioritize cloud defense in depth. These measures are indispensable for protecting critical assets and upholding the integrity of cloud-based systems. By establishing a comprehensive security plan, organizations can effectively convey their commitment to security and lay a solid foundation for a resilient and secure cloud environment.

CloudCasa Partners With Clastix To Ready Namespace-as-a-Service For Mass Adoption

With Kubernetes, companies have the ability to spin up applications with the click of a button or a declarative one-line command statement. As they spin up the services, they are hosting them within clusters, but they do not really want to deploy multiple clusters for each application or service that they’re looking to host within their website or within their application.

Monitoring Velero and Enabling Email Alerts for Kubernetes Backup and Restore Failures

Open source Velero is a popular choice amongst Kubernetes community for backup of their application. Along with scheduling regular backups for your Kubernetes clusters, monitoring Velero and getting automated alerts for failed Velero backups is also important. When your most important backup fails, you want to know about it immediately and make sure your application notifies you.

How to detect and stop DDoS attacks in a Kubernetes environment

DDoS or Distributed Denial of Service attacks have been around for a while and are notorious and painful to deal with (as with any other attack). As the name suggests, a DDoS attack causes an application or service to become unavailable to users due to resources exceeding it’s capacity and causing the app to either crash or become unresponsive. DDoS is a form of DoS where the attack comes from multiple sources (bots), usually spread across geographical locations.
