Calico Open Source is an industry standard for container security and networking that offers high-performance cloud-native scalability and supports Kubernetes workloads, non-Kubernetes workloads, and legacy workloads. Created and maintained by Tigera, Calico Open Source offers a wide range of support for your choice of data plane whether it’s Windows, eBPF, Linux, or VPP. We’re excited to announce our new certification course for Azure, Certified Calico Operator: Azure Expert!

Hey everyone. We’re excited to announce the release of Calico v3.23! Thanks to everyone in the community who contributed to the release. We could not have fitted this many improvements in without you. To view the detailed release notes, please visit us here. While we have many improvements in this release, here’s a brief overview of some of the larger features to be aware of.

An important part of any Kubernetes cluster is the underlying containers. Containers are the workloads that your business relies on, what your customers engage with, and what shapes your networking infrastructure. Long story short, containers are arguably the soul of any containerized environment. One of the most popular open-source container orchestration systems, Kubernetes, has a modular architecture.

In previous blog posts, my colleagues and I have introduced and explored the Calico eBPF data plane in detail, including learning how to validate that it is configured and running correctly. If you have the time, those are still a great read; you could dive in with the Calico eBPF Data Plane Deep-Dive.

Amazon’s custom-built Graviton processor allows users to create ARM instances in the AWS public cloud, and Rancher K3s is an excellent way to run Kubernetes in these instances. By allowing a lightweight implementation of Kubernetes optimized for ARM with a single binary, K3s simplifies the cluster initialization process down to executing a simple command.

The rise of cloud native and containerization, along with the automation of the CI/CD pipeline, introduced fundamental changes to existing application development, deployment, and security paradigms. Because cloud native is so different from traditional architectures, both in how workloads are developed and how they need to be secured, there is a need to rethink our approach to security in these environments.

Calico Cloud has just celebrated its 1-year anniversary! And what better way to celebrate than to launch new features and capabilities that help users address their most urgent cloud security needs. Over the past year, the Tigera team has seen rapid adoption of Calico Cloud for security and observability of cloud-native applications.

First-generation security solutions for cloud-native applications have been failing because they apply a legacy mindset where the focus is on vulnerability scanning instead of a holistic approach to threat detection, threat prevention, and remediation. Given that the attack surface of modern applications is much larger than in traditional apps, security teams are struggling to keep up and we’ve seen a spike in breaches.

The Project Calico community is one of the most collaborative and supportive communities in the open-source space. Our community has shown great engagement through the years, which has helped us maintain and grow the project. Thanks to our 200+ contributors from all over the world, Calico Open Source (the solution born out of the project) is powering 1.5M+ nodes daily across 166 countries.

Central processing units (CPUs) can be compared to the human brain in that their unique architecture allows them to solve mathematical equations in different ways. x86 is the dominant architecture used in cloud computing at the time of this writing; however, it is worth noting that this architecture is not efficient for every scenario, and its proprietary nature is causing an industry shift toward ARM.
