Let's face it: no one likes patching. When I was a practitioner, we always put off patching until it was absolutely necessary. Until a business need – such as updating an application version or support ending for a version – arose, we didn't patch because "If it ain't broke, don't fix it." We all know this is a bad practice; let's remind ourselves why. The longer a system goes without being patched, the more changes will accumulate.
Sysadmins, short for system administrators, serve as a crucial subset of IT engineers and support staff and are often under-appreciated. Sysadmins are the lynchpins that provide continuity, performance, and security to the systems that connect every corner of the world. When COVID-19 scattered large workforces in offices across small home office networks, organizations relied on their sysadmins more than ever before to maintain work processes.
Today we are pleased to announce GitLab support on CircleCI. Teams using GitLab SaaS can now build, test, and deploy on CircleCI, and access CircleCI’s most popular features like Docker layer caching and automatic test-splitting. GitLab is now the third version control system we support, in addition to GitHub and Bitbucket.
GitHub is one of the most popular source control platforms available. It relies on Git concepts, and millions of developers use it. GitHub Actions embrace all aspects of what source control needs, such as branching, pull requests, feature flags, and versioning. It also integrates nicely into third-party continuous integration and continuous development (CI/CD) pipelines or deployment tools like Azure DevOps, Jenkins, GitLab, and Octopus Deploy.
Cilium is a Container Network Interface (CNI) for securing and load-balancing network traffic in your Kubernetes environment. As a CNI provider, Cilium extends the orchestrator’s existing network capabilities by giving teams more control over how they build their applications and monitor traffic. For example, vanilla Kubernetes installations typically rely on traditional firewalls and Linux-based network utilities like iptables to filter pod-to-pod traffic by an IP address or port.
In Part 1, we looked at some key metrics for monitoring the health and performance of your Cilium-managed Kubernetes clusters and network. In this post, we’ll look at how Hubble enables you to visualize network traffic via a CLI and user interface. But first, we’ll briefly look at Hubble’s underlying infrastructure and how it provides visibility into your environment.
In Part 2 of this series, we showed how Hubble, Cilium’s observability platform, enables you to view network-level details about service dependencies and traffic flows. Cilium also integrates with various standalone monitoring tools, so you can track the other key metrics discussed in Part 1. But since the platform is an integral part of your infrastructure, you need the ability to easily correlate Cilium network and resource metrics with data from your Kubernetes resources.
