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.

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.

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.

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.

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.

Tigera provides the industry’s only active Cloud-Native Application Protection Platform (CNAPP) with full-stack observability for containers, Kubernetes, and cloud. Calico prevents, detects, troubleshoots, and automatically mitigates exposure risks of security issues in build, deploy, and runtime stages across multi-cluster, multi-cloud, and hybrid deployments. Calico works with popular managed Kubernetes services such as AKS, EKS, and GKE, as well as self-managed Kubernetes distributions including Red Hat OpenShift, SUSE/Rancher, VMware Tanzu, and Mirantis.

Calico/VPP data plane renderer was introduced as Tech Preview in Calico 3.19 for Kubernetes. It leverages the FD.io/VPP userspace data plane which brings great benefits in terms of performance and flexibility for large-scale Kubernetes clusters. Thanks to its fast IPSec & Wireguard implementation, it makes it possible to provide intra-cluster full mesh crypto without compromising performance. Beyond performance, it implements differentiated features like MagLev based load balancing with DSR for k8s services making it a good choice for large-scale applications having strong high availability requirements. This is the first release but moving forward, it will provide support for superfast packet-oriented virtual interfaces as well TCP/UDP/Quic stack to applications having extreme networking performance.

Learn how eBPF will bring a richer picture of what's going on in your cluster, without changing your applications. With eBPF we can safely collect information from deep within your applications, wherever they interact with the kernel. For example, collecting detailed socket statistics to root-cause network issues, or pinpointing the precise binary inside a container that made a particular request for your audit trail. This allows for insights into the behavior (and security) of the system that previously would have needed every process to be (manually) instrumented.

Attackers are continuously evolving their techniques to target Kubernetes. They are actively using Kubernetes and Docker functionality in addition to traditional attack surfaces to compromise, gain required privileges and add a backdoor entry to the clusters. A combination of Kubernetes security and observability tools is required to ensure the cloud infrastructure monitoring and lockdown and to enable DevSecOps teams with the right tools for the job.

It’s a daunting task starting down the path to securing your workloads running on Kubernetes in the Cloud. There are no shortages of vendors with great tools in the Cloud security space. There is a multitude of domains that must be accounted for, along with internal challenges in bringing an organization along into new ways of thinking. This talk will focus on Discover’s Cloud security journey, with an overview of how the program has evolved over the last 4 years, key capabilities & concepts that have been embraced and challenges faced.

Containers, Microservices, and cloud-based applications have revolutionized the way companies build and deliver products globally. This has also changed the attack surface and requires very different security strategies and tools to avoid exposure to sensitive information and other cyber attacks. Regulatory compliance has also evolved making it ever so important for companies to adapt to this new paradigm.

Kubernetes is being adopted by every major enterprise on the planet for deploying modern, containerized applications. However, containers are highly dynamic and break their existing security models. Tigera provides zero-trust network security and continuous compliance for Kubernetes platforms that enables enterprises to meet their security and compliance requirements.
Tigera’s technology is recognized and trusted as the de facto standard for Kubernetes network security. Our open source software, Tigera Calico, provides production-grade security, and our commercial offerings layer on advanced security capabilities, enterprise controls, and compliance reporting.
Kubernetes Requires a Modern Approach to Security and Compliance:
- Zero-Trust Network Security: With 40% or more of all breaches originating from within the network, you must always have to assume that something has been compromised. Applications running on Kubernetes make heavy use of the network for service to service communication. However, most clusters have been left wide open and are vulnerable to attack. A zero trust approach is the most secure way to lock down your Kubernetes platform.
- Continuous Compliance: Kubernetes is dynamic and constantly changing. Moments after a compliance audit is completed the environment will have changed again. A continuous compliance solution is the only way to prove that your security controls have been implemented properly now and historically.
- Visibility and Traceability: Applications running on Kubernetes Platforms have constantly changing IP addresses and locations that makes it impossible to use traditional flow logs to debug issues and investigate anomalous activity. The only accurate approach is to use Kubernetes labels and workload identity in your netflow logs.
- Multi-cloud and Legacy: Many applications running on Kubernetes will not be greenfield. Applications often need to communicate securely with other systems outside of the cluster, such as on-premises or cloud-based VMs, bare metal servers and databases. To achieve zero trust security for Kubernetes, your security policies must be capable of expanding beyond the cluster.
