Repository and Artifact Caching

Accelerate CI/CD

Deliver artifacts and containers at scale with less infrastructure pressure.

Varnish Enterprise integrates into your CI/CD toolchain to cache and serve dependencies at high speed, reducing origin traffic, cutting cloud costs, and increasing pipeline reliability.

Faster Builds, Smarter Caching

DevOps Acceleration Starts with the Right Cache Layer

DevOps teams rely on efficient access to shared components and containers, but build pipelines and deployments are affected by:

  • Redundant dependency downloads
  • Network latency and high egress fees
  • Repository bottlenecks during CI/CD surges
  • Slow data access
  • Scaling limitations

Varnish caches artifacts and containers close to your teams, eliminating latency, reducing database load, and keeping pipelines fast and responsive.

What Varnish Enterprise Does

Varnish Enterprise integrates directly into your software delivery path, between developers, CI/CD tools, and your artifact repositories, storing and re-serving dependencies, packages, containers, and more.

  • Cache and serve artifacts, containers, and packages at high speed. 
  • Compatible with tools like JFrog Artifactory, Sonatype Nexus, Maven, Gradle, pip, npm, Docker, GitHub
  • Deployable in the cloud, on-premise, edge or hybrid environments.
  • Comprehensive, programmable delivery architecture includes security, load balancing and observability tooling.

How It Works in Your Toolchain

Varnish sits transparently between developers, CI/CD systems, and artifact or container repositories. When a request for an artifact, package, dependency or container layer is made, Varnish evaluates whether the object is already cached locally.

If the object is cached, Varnish serves it directly from local storage, dramatically reducing retrieval latency, and improving pipeline responsiveness. If the object is not cached, Varnish fetches it from the origin and stores it locally, ensuring subsequent requests are served instantly from cache.

Use Varnish to:

  • Accelerate dependency resolution and image pulls

  • Reduce load on artifact servers

  • Eliminate redundant transfers

  • Support globally distributed teams with low-latency local access

Enterprise-Grade Caching

Key Features for Software Distribution

Varnish is not just fast but secure, scalable, and suitable for enterprise environments with strict security and access policies.

Access Control Integration
Varnish respects access policies by integrating with access control systems. This allows secure delivery of cached artifacts without compromising authentication or authorization.
Massive Storage Engine (MSE)
Efficient, disk-based caching architecture with configurable storage policies. Supports large-scale caching for containers, binaries, and package files.
Varnish Clustering
Clustered deployment options for horizontal scaling and high availability. Share cached content across regions or data centers.
End-to-End TLS Encryption
Secure delivery of artifacts and packages using full TLS support for client-to-cache and cache-to-origin connections.

All about MSE

Use Case: Accelerating Delivery Across Self-Hosted and Cloud Artifactory Deployments

Artifact repositories like JFrog Artifactory are critical to CI/CD, but both self-hosted and cloud-hosted deployments introduce operational challenges.

Self-Hosted Artifactory Challenges

  • Degrades under load
  • Scaling requires hardware
  • Centralized failure risk

Cloud-Hosted Artifactory Challenges

  • Region-based latency
  • Usage-based billing growth
  • Infrastructure control limits

Varnish integrates with both self-hosted and cloud Artifactory environments to deliver a consistent, high-performance caching layer that:

  • Caches artifacts close to users and pipelines
  • Reduces origin fetches and cloud egress
  • Improves delivery consistency and system resilience
  • Works across on-prem, hybrid, and multi-cloud setups

Implementation and Deployment

Varnish can be deployed as:

  • A local caching node in each region or data center
  • A global cluster serving teams across multiple locations
  • A containerized edge service in front of specific tools (Artifactory, Nexus, etc.)

The Varnish Artifact Cache is part of a fully programmable delivery layer, integrating caching, traffic routing, security, and observability into a unified architecture. It fits seamlessly into existing CI/CD pipelines and supports automation, monitoring, and scaling through standard tooling.

Proven Efficiency at Scale

Cut Infrastructure and Cloud Spend with Smarter Caching

Varnish Enterprise enhances performance and cuts costs by reducing load, bandwidth, and infrastructure complexity in software development.

Less Cloud Egress
Caching repeated requests reduces outbound traffic from cloud storage and repositories—cutting egress fees and easing network load in CI/CD pipelines.

Reduced Repository Load
Offloading redundant traffic from tools like Artifactory and Nexus maintains backend performance and delays costly scaling during peak demand.

Leaner Infrastructure
Serving requests closer to users and CI systems cuts reliance on central resources, improves latency in hybrid setups, and ensures stable performance.

Not All Caches Are Built for DevOps

Beyond Built-In Caching

Engineering teams often depend on built-in, open-source, or freemium caching, but these fall short at scale. Varnish delivers what others can't: consistent performance, architectural control, and resilience under pressure.

Local/Remote Build Caches (Bazel, Gradle, Maven)
Fragmented across teams, tool-specific, struggles with multi-terabyte datasets.

Built-in Repository Caching (Artifactory, Nexus)
Optimized for storage, not speed; high cloud egress costs; limited concurrency handling.

Open-source Reverse Proxies (Nginx, Squid)
Lack fine-grained invalidation, persistent storage, and native DevOps integration.

Memory Caches (Redis, Memcached)
Volatile, non-persistent; limited to internal acceleration, not full pipeline caching.

For Developers

Why Varnish Works

Varnish Enterprise is built for large-scale, artifact-heavy environments. For platform engineers and build infrastructure teams, it solves key challenges:

Persistent, Policy-Driven Cache Layer
Varnish is a dedicated delivery layer—not a plugin or retrofitted proxy. You control what gets cached, when it refreshes, and how it scales.

Predictability Under Load
Varnish absorbs bursty traffic without overwhelming artifact servers, even when hundreds or thousands of jobs request the same binary.

Architectural Flexibility
Varnish runs close to runners, in edge zones, or alongside repositories—via containers, bare metal, or cloud. No forced topologies or vendor lock-in.

Result: Higher hit rates, fewer origin failures, and scalable infrastructure without overbuilding.
