Why Use Varnish?
Drastically reduces server loads
The biggest reason to use Varnish is so you can serve thousands of concurrent requests per second without overloading your web server and database server. Because Varnish can serve cached content directly from primary memory, there is no disk i/o operation to slow things down. No database calls are made, and there is absolutely no processing involved. Results are that response times and the server resource usage are always kept at a bare minimum.
Varnish is highly customizable
In the right hands VCL is very powerful and allows you to modify nearly every aspect of HTTP request and response. Our engineers can help you customize Varnish as per your requirements. We play with the Varnish Configuration Language (VCL) file - to fine tune your performance and tell Varnish exactly how to handle the caching process including when and what to cache, when not to cache, and how long to keep the cached content in memory.
Increased resilience with High Availability
If your application or website is mission critical - high availability can further improve overall performance as well as increase resilience to hardware failure. We have deep experience in turning pairs of Varnish Cache servers into "highly available" caching clusters. This not only removes a single-point-of-failure, but can help reduce cache misses even further!
