Content Delivery Circle

Hybrid CDN Software

Get More from CDN Investments

Commercial CDNs can deliver content and data, but many find that their exclusive use presents three risks:

Costs become unsustainable as traffic increases, in a way that’s hard to predict and budget for.

Unexpected outages harm customer experience and damage revenue.

Lack of integration between CDNs reduces cache hits and puts new pressure on the origin.

Reduce CDN Risk

Hybrid Reliability and Resilience

Varnish Enterprise caching software complements existing CDN usage to accelerate HTTP delivery, protect core infrastructure and improve CDN synchronization.

It plugs straight into existing content delivery architectures to make costs more predictable, maintain uptime during outages and increase cache hits.

Deploy Anywhere

Adaptable for Every Need

A hybrid CDN supplements existing content delivery services with private CDN components to boost cost-efficiency and performance.

Deploy Varnish flexibly alongside existing CDNs at: 

The Edge: For greater efficiency and lower latency, including deep in ISP networks

The Origin: To reduce backhaul and add resilience

Both: Deploy caches in two or three-tier setups, as edge PoPs, mid-tier caches, origin shield, and Super PoPs

Offload More Traffic

A Single CDN Entry Point

With Varnish Enterprise in a CDN setup, origin servers see significantly lower egress and users get content faster.

Disk-based caching: Store vast amounts of data in cache to reduce backend load and serve multiple CDNs from a single entry point.

Lightning fast invalidation and revalidation: Synchronize and update CDNs instantly for higher cache efficiency, easier ops and better user experience.

Request collapsing: Combine requests for identical content so that only one hits the origin.  

Content replication: Real-time content replication across Varnish servers for high availability.

Sync with Akamai and Fastly

Work Well With Others

In some multi-CDN setups it's difficult to synchronize caching behavior. Not so with Varnish.

Coordinate Varnish and Akamai cache logic for easier invalidation and revalidation.

Port VCL from Fastly to Varnish quickly, for predictable CDN costs, more logic at the edge and robust failover.

Built-in request routing, load balancing and geo-location routes users to the best available CDN, for faster, higher quality experiences.
