Kubernetes provides abstraction and simplicity with a declarative model to program complex deployments. However, this abstraction and simplicity create complexity when debugging microservices in this abstract layer. The following four vectors make it challenging to troubleshoot microservices.
As we enter a new year, it’s an appropriate time to reflect on our achievements at Tigera and how much Calico Enterprise has evolved over the past year as the industry’s leading Security and Observability solution for Kubernetes Networking and Microservices.
As an AWS Advanced Technology Partner with AWS Containers Competency, Tigera is thrilled to announce that Calico and Calico Enterprise are both now available as AWS Quick Starts. If you’re unfamiliar with the concept, an AWS Quick Start is a ready-to-use accelerator that fast-tracks deployments of key cloud workloads for AWS customers.
Calico and Kubernetes go hand-in-hand. Kubernetes is the de facto standard for deploying and managing container-based applications at scale, both on-premises and in the cloud. Calico continues to be the most popular open-source networking and network security solution for Kubernetes. Despite the cataclysmic events that occurred in 2020, the Calico community, supported by the team at Tigera, remained focused and achieved several major successes. We are excited to share these highlights.
A few weeks ago a solution engineer discovered a critical flaw in Kubernetes architecture and design, and announced that a “security issue was discovered with Kubernetes affecting multi-tenant clusters. If a potential attacker can already create or edit services and pods, then they may be able to intercept traffic from other pods (or nodes) in the cluster.” If a hostile user can create a ClusterIP service and set the spec.externalIP field, they can intercept traffic to that IP.
The Domain Name System (DNS) is a naming system for computers, services, or other resources connected to the Internet or a private network. DNS translates domain names to the numerical IP addresses needed for locating and identifying computer services and devices. For decades It’s been an essential component of the Internet. It’s an essential part of Kubernetes as well, and is used to determine how workloads connect to Kubernetes services as well as resources outside the cluster.
Today, we are excited to announce our commitment to support Calico and Calico Enterprise for the Amazon EKS-Distro, a Kubernetes distribution based on and used by Amazon EKS. EKS-D enables you to create reliable and secure Kubernetes clusters using the same versions of Kubernetes and its dependencies deployed by Amazon EKS. We view EKS-D as further confirmation of the central role that Kubernetes plays in today’s IT infrastructure.
Benchmark tests measure a repeatable set of quantifiable results that serve as a point of reference against which products and services can be compared. Since 2018, Alexis Ducastel, a Kubernetes CKA/CKAD and the founder of InfraBuilder, has been running independent benchmark tests of Kubernetes network plugins (CNI) over a 10Gbit/s network. The latest benchmark in this periodic series of tests was published in September, and was based on CNI versions that were up-to-date as of August 2020.
If you’re an SRE or on a DevOps team working with Kubernetes and containers, you’ve undoubtedly encountered network connectivity issues with your microservices and workloads. Something is broken and you’re under pressure to fix it, quickly. And so you begin the tedious, manual process of identifying the issue using the observability tools at your disposal…namely metrics and logs.
We’re excited to announce that Calico Enterprise, the leading solution for Kubernetes networking, security and observability in hybrid and multi-cloud environments, now includes encryption for data-in-transit.
