In today's fast-evolving software landscape, teams behind SaaS, standalone software, and DBaaS offerings grapple with networking, security, and scalability challenges. Traditional networking solutions often fail to support distributed systems' complex demands spanning multiple clusters and clouds. Furthermore, the rise of microservices intensifies the need for fine-grained security measures and deep visibility into application communications.
Cilium is purpose-built to secure and accelerate the delivery of cloud native applications. It leverages eBPF to provide API-aware networking and security with unparalleled granularity without compromising performance. With Cilium, SaaS, software, and DBaaS teams can establish infrastructure capable of scaling their products globally to reach customers wherever they may be. Cilium enables the creation of secure Kubernetes multi-tenant environments, empowering these companies to meet the challenges of modern software deployment head-on.
eBPF and Cilium helped us to push the boundaries both within operations and also with product development. To do things safer, faster and more easily than what we could have with traditional techniques. The overlay of features in a single product, compatibility with multiple cloud providers, and ability to just run it. These three things are what made Cilium an obvious choice for us
Datadog uses Cilium to secure and monitor the network traffic of their containerized applications running on Kubernetes
READ THE CASE STUDYOne of the core tenets of DevOps is automation. Cilium's architecture ensures that all its components can be deployed automatically, integrating into existing workflows and augmenting automation capabilities. Platform engineering teams can seamlessly integrate Cilium into their CI/CD pipelines, ensuring continuous delivery and integration without manual intervention.
Cilium is designed to be configured using an API. This aligns with the GitOps principles, where the desired state of infrastructure is declared in code and stored in Git repositories. The API-driven model of Cilium enables organizations to manage, scale, and modify their infrastructure using code, ensuring consistency and repeatability.
ClickHouse turned to Cilium as their preferred networking solution to simplify the process of isolating customers from each other
READ THE CASE STUDYCilium's Hubble Service Map allows platform teams to furnish application developers with a portal to view their own workloads, dependencies, and network flows. This self-service model makes it easier to identify service connections, calls, and even DNS operations, all crucial for diagnosing application networking problems. The service map helps streamline the onboarding of new applications and teams and accelerates the debugging process.
By mitigating disputes between application and infrastructure operation teams, Cilium accelerates the investigation of application-layer issues, enabling frictionless, self-service root cause analysis for developers.
From experience, we know that getting network policy correct is difficult and when you do get it wrong it is a nightmare. Trying to understand what’s going on with traditional tooling means, you probably throw three engineers at the problem for five hours while with Hubble you know what’s happening in about three seconds. It was one of those very easy trade offs to explain to my CEO. We’re going to encounter the cost of debugging, let’s make it a lot less expensive.
Ascend turned to Cilium as their CNI which simplified integrating into customer networks, eliminated their IP churn and density issues.
READ THE CASE STUDYFor enterprises building muti-tenant architectures, Cilium enforces isolation between tenants and ensures different teams can safely run on the same platform. With Cilium's multi-tenant observability features, teams can easily access application metrics without compromising security. Traditional logging systems often fall short when segregating data by tenants. Cilium provides multi-tenant, self-service access using the OpenID Connect (OIDC) standard. Teams can have RBAC-based access to relevant data and connectivity metrics, such as network policy drops, DNS lookup failures, and more.
