Varnish Enterprise

Varnish Enterprise is a programmable caching and delivery layer deployed in front of backend systems to accelerate HTTP traffic, reduce infrastructure strain, and enable fine-grained control over request/response behavior. It functions as a reverse proxy and HTTP engine that handles artifact caching, API offloading, media streaming, and dynamic content delivery across on-premise, cloud, edge, and hybrid environments. The platform supports deployment in Kubernetes-native setups, bare metal, VMs, and private or public clouds, with capabilities including disk-based persistent caching, TLS support, traffic policies, and 45+ VMODs for custom edge logic and routing.

Core Strengths:

• Intercepts and caches HTTP/HTTPS interactions before they reach your backend.
• Accelerates web pages, APIs, streaming, and artifact delivery.
• Implements advanced application logic using Varnish Configuration Language.
• Supports persistent storage for large cache datasets.
• Provides integrated TLS/mTLS, access control, and request filtering.
• Offers real-time observability with metrics and logs.
• Includes 45+ VMODs for modular, custom request handling.

Use Cases:

1. Web content acceleration and caching.
2. API and microservice speed optimization.
3. CI/CD artifact caching and developer platform performance.
4. Video and media delivery at scale.
5. Edge traffic routing and control.
6. Private CDN infrastructure with fine-grained policies.
