VARNISH VIRTUAL REGISTRY
Faster builds, lower cost, no vendor lock-in.
Varnish Virtual Registry, also known as Orca, is a high-performance caching, routing, and observability layer that accelerates access to software artifacts across modern software delivery and AI workloads. It's a vendor-neutral way to reduce build delays, infrastructure costs, egress, and dependency on overloaded and expensive repository platforms.
Modern software delivery no longer runs at human speed.
CI/CD pipelines, Kubernetes clusters, build farms, AI agents, and GPU workloads pull dependencies, containers, source, and model assets continuously. Every install, container pull, and dependency update adds latency, saturates backends, and runs up cloud egress. The more concurrency and the larger the artifacts, the more pressure lands on the registries underneath.
Repositories saturate under load
Backend, egress, and rate limits make dependency resolution a bottleneck.
Costs scale with traffic
Agentic downloads and repository expansion grow spend, not delivery speed.
Distributed teams hit different walls
Developers, runners, and clusters each hit their own latency and lock-in.
Why Virtual Registry
Vendor-neutral performance, control, and resilience.
The usual answer to artifact pressure is to scale the infrastructure underneath it: bigger Artifactory or Nexus, more backend, more egress, higher upstream bills every year. Orca takes a different position. It sits in front of the registries you already run as a single, vendor-neutral access layer, so performance scales without the systems behind it, and control and resilience stay with you, not your repository vendor.

THE DIFFERENCE IS WHERE THE WORK HAPPENS.
Scaling the repository moves the bottleneck and grows the bill. Caching at the point of consumption removes the bottleneck and leaves your upstream spend where it is.

Expanding the repository handles more load, but every pull still hits the backend, so latency, egress, and spend keep rising with demand.
Architecture
Where Virtual Registry sits in your stack
One acceleration layer between every registry you pull from and everything that pulls from it: CI, CD, and developers.
“Varnish has allowed our on-prem Universal Repository deployments to support workloads from our large in-house compute farm which support our quants who run huge batch jobs. It has also allowed us to improve performance of PyPI and NuGet repos and replace our use of httpd to load balance between repository servers with a single Varnish Layer.”

Capabilities
What Virtual Registry does
A single cache in front of every registry
Point your package managers and clients at an Orca endpoint and it does the rest: a cache lookup, a single upstream fetch, and repeated pulls served without touching the origin.
01
Artifact-aware acceleration |
Caches container layers, package files, binaries, Git LFS objects, and model artifacts, while keeping metadata, manifests, and indexes fresh with revalidation. |
REQUEST COALESCING PERSISTENT CACHING |
02
Multi-registry routing and virtualization |
Presents your repositories, registries, object stores, and cloud artifact services through one logical endpoint. |  |
03
Authentication-preserving private caching |
Accelerates private artifact traffic without bypassing registry security. Pairs with Artifact Firewall for request-time package policy. |
PRESERVES ACCESS SHARED EFFICIENCY |
04
Operational visibility and flexible deployment |
Built for platform teams running distributed delivery infrastructure. |
OPENTELEMETRY RUNS ANYWHERE |
Where Virtual Registry pays off
Reach for Virtual Registry wherever repeated artifact traffic is slowing builds, loading origins, or running up cost across distributed software delivery.
Accelerate CI/CD dependency fetches
Serve packages, containers, and modules from cache so runners stop waiting on upstream registries.
Shield origins during outages and migrations
Keep serving cached artifacts when registries, object stores, or networks are slow, overloaded, or being moved.
Cache private artifacts without duplication
Let approved users and runners share cached private binaries while upstream access controls stay intact.
Serve multi-region build infrastructure
Put a cache close to every region, runner, and cluster without centering delivery on one vendor.
Feed AI and model workloads
Shield object storage and accelerate both model delivery and the build and packaging of models themselves.
Replace fragile cache workarounds
Swap brittle NGINX, Squid, or httpd proxies for a purpose-built, artifact-aware acceleration layer.
Results
Proven in production
Across distributed CI/CD, multi-region build infrastructure, and compute-heavy environments, teams use Virtual Registry to cut backend load and cost while builds get faster and more reliable.
