The Delivery Layer for Platform Teams
Varnish Enterprise is the high-performance delivery layer that gives platform engineering teams speed, control, and efficiency across, CI/CD pipelines, APIs, web applications and modern data workflows.
Built for Demanding Delivery Workloads
From CI/CD pipelines to internal developer tools, platform teams face mounting delivery demands: bloated artifact repositories, backend overload, unpredictable latency, and rising infrastructure costs. Varnish Enterprise solves these challenges with a programmable cache layer that accelerates artifact delivery, reduces infrastructure strain, and gives DevOps teams the control they need to scale platforms cleanly. Use it to support:
- Artifact caching and CI/CD acceleration
- Developer platform performance
- API and service offload
- Media streaming and edge delivery
- Object storage and S3 acceleration
- Private CDN deployment and custom routing
How Varnish Works
Varnish intercepts HTTP traffic before it hits your backend. It caches software artifacts, content, and data closer to users or build systems, reducing fetch times and system load.
- Varnish intercepts HTTP requests and checks whether the requested content is already stored in cache.
- If it is, the response is delivered instantly, eliminating the need to contact the backend.
- If not, Varnish fetches the object from the origin, stores it locally according to configurable rules, and serves it to the client.
- The result: a dramatic reduction in latency, origin traffic and compute load, even infrastructure spend. The entire process is governed by Varnish Configuration Language (VCL), a fast, in-process domain-specific language that gives platform and infrastructure teams deep control over how artifacts, content, and APIs are delivered, without modifying backend logic or app code.
Run Varnish Anywhere
Deploy in front of any backend
- Artifact repositories and developer portals
- Web apps, APIs, and headless services
- Websites and dynamic content
- Video origins, CDN edges, and media libraries
- Object storage
Deploy in any environment
- Kubernetes-native (via Helm and Docker)
- Edge nodes and remote POPs
- Bare metal or VM-based infrastructure
- Private or public cloud
Unify and control delivery
- Bring together caching, routing, access control, and observability across all workloads.
- Simplify architecture, enable consistent policies, accelerate changes, without modifying backend code.
- Configure using VCL, API, or use the Varnish Controller UI for centralized orchestration.
