WEB APPLICATION ACCELERATION
Streamline Your Web Stack While Reducing Operational Costs
Deploy Varnish Enterprise to offload traffic, reduce infrastructure expenses and ensure faster content delivery to larger audiences.
Varnish Enterprise
Lower the Cost of Scaling Web Applications
Do traffic peaks and technical constraints make it difficult to deliver fast, scalable and cost-efficient digital experiences?
Varnish Enterprise HTTP caching software offloads traffic and enables faster access to content and data, helping your web service overcome the challenges of scale.
Improve performance. Achieve more cache hits and ensure faster, more reliable content delivery even under peak traffic conditions.
Reduce infrastructure costs. Decrease load on backend applications, in the cloud, on-premises and microservice environments.

Reduce Backend CMS Requests with Dedicated Caching
Deploy Varnish Enterprise software in front of CMS providers like WordPress, Magento and Drupal to increase cache hit ratios and cache previously uncacheable content, significantly reducing backend requests.
Cache all kinds of HTTP responses, including HTML, dynamic content, JSONs and REST APIs, to minimize latency and avoid data transfer costs and database queries. By shielding applications with Varnish you also protect online revenue by avoiding downtime during peak traffic.
“We immediately saw how every tweak translated to performance in real time. Nikon is really excited about how fast the site feels now.”

CDN Performance Enhancement
Varnish acts as a mediator between your backends and CDNs, improving synchronization, efficiency, and performance. It integrates with all major CDNs to serve as a content aggregator and defensive layer:
Increase Cache Hits
Cache more content and address gaps in CDN caching.
Minimize Backend Load
Consolidate cache misses to minimize backend requests.
Ensure Users See Up to Date Content
Coordinate cache invalidation for consistent performance.
Varnish for Kubernetes
Enhance Microservices
Incorporate Varnish clusters into your containerized environments to scale microservice-based web applications effectively. Sophisticated caching mechanisms increase the capacity of existing architectures and reduce the number of application pods needed during heavy load.
Varnish Enterprise’s cloud tooling includes:
- Helm Charts: Deploy and manage Varnish seamlessly in Kubernetes environments.
- K8s Clustering: Support replication, sharding, and dynamic DNS configurations.
- S3 Support: Handle multiple IPs from a single S3 endpoint, minimizing error rates.
- ActiveDNS: Adapt to changing DNS results to support dynamic backends.
- Load Balancing: Apply different load balancing policies over static or dynamic backends to optimize performance.
- Enhanced Caching Capabilities: POST and GraphQL caching to improve cache hit rates and reduce latency.
- Observability: Granular metrics and statistics with output to Prometheus.
Economic Impact
Three Ways Varnish Optimizes Web Apps
Higher Cache Hit Rates. Cache a wide variety of content types, including secure transactions and dynamic content, with advanced purging and revalidation tools.
Avoid Rebuilding the Cache. Persist the cache’s memory following outages or restarts.
Combine Backend Requests. Increase the capacity for concurrent users by combining multiple cache misses into a single backend request.
These capabilities not only reduce backend connection counts but also allow for scaling in pods and minimizing the number of cluster nodes needed, without sacrificing performance.
Enterprise Features
Built for the Internet’s Demands
Persistent Cache
Economical storage for large objects and datasets, ensuring pods do not lose value or require rebuild after restart.
Soft Purge
Fetch content asynchronously to serve stale objects during updates, enhancing user experience.
Set Short TTLs
Deliver up-to-date content within regulatory timeframes, reducing costly backend revalidation.
Client-Side Personalization
Dynamic page assembly, plus deconstruction of authenticated data into JSON format to make components reusable and boost cache efficiency.
Smart Invalidation
Utilize request-based invalidation or encode dynamic content versions in unique URLs to prevent unnecessary cache purges and handle content variants.
Stale Content
Serve stale content in case of backend errors.
Key-based Purge
Purge by paths, headers, or cache keys to update specific content and its variants efficiently with each change.
SSL/TLS Termination
Offload encryption to speed up content delivery while enhancing security.
How Varnish Works
Success Stories
CBC
Varnish Enterprise helped CBC secure huge performance and reliability gains while lowering CAPEX and OPEX by 30% and reducing infrastructure needs.
“The CBC website could not do without it.” – Massimo Mollica, Manager, CBC/Radio-Canada
Future Publishing
The publishing powerhouse uses Varnish to ensure high availability and scalability, overcome Fastly outages and slash downtime.
"When Fastly goes down, we can just swing everything to London and serve content directly from Varnish Enterprise." - Toby Jackson, Global SRE Lead, Future
Intersport
With Varnish Enterprise, the retailer could handle traffic spikes, deliver fast page loads and ensure good user experience.
"Varnish offers the ability to adopt a flexible and configurable cache strategy managed by our internal devops team. Other tools don’t make it as easy to change." -Michael Alimi, CTO, Intersport
Why Varnish Stands Out
Performance Under Pressure
Under extreme traffic conditions, where other solutions falter with dropped connections and latency spikes, Varnish is robust and reliable. Offering high concurrency, throughput, and stability, it is ideal for demanding applications.
The Privacy of a Dedicated Solution
Deploy Varnish Enterprise on dedicated infrastructure, tailored to unique requirements, whether in the cloud, in containers, or on-premise.
Power Multiple Use Cases
Varnish is a comprehensive tool that integrates caching, security, load balancing, API gateway functionality, observability, and high availability into a single robust platform.
Integrated Edge Compute
Adaptive Real-Time Cache Controls
Varnish Configuration Language (VCL) provides precise control over caching behaviors and object management, allowing for content manipulation directly in the cache without performance loss. This capability moves critical application logic closer to your users, enabling innovation and building more responsive, secure web experiences.
Execute Code at the Edge: Manage request handling, routing, caching, and access controls effectively. Build tailored user experiences, reduce load times, and ensure security with complete visibility into caching performance.
“Within three months, we have already saved at least one work week because Varnish Enterprise has not failed once.”
