May’s been a busy month here at MIDAS HQ!

Not only have we migrated Certificate Authorities to Let’s Encrypt, but we’re also been testing a new Content Delivery Network (CDN) feature in MIDAS.

To explain what a CDN does, imagine viewing a photograph online. That photograph will be stored on a web server somewhere. If you’re in the UK and the server where the photograph resides is located in Australia, it will take your browser longer to establish a connection and download the image from the other side of the world than it would do if the server was located in the same country as the person viewing the image. Now, we may only be talking of a few fractions of a second longer, but if you’re viewing a webpage containing several photographs, that can soon add up!

A Content Delivery Network vastly improves performance by storing (or “caching”) a copy of the photograph from the source server on multiple servers all around the world. Then, when a viewer requests the photograph, the CDN serves a cached copy of the file from whichever server is geographically closest to the viewer. This greatly improves the load time for the viewer, and also reduces the load on the original server (as the photograph is served from the CDN “cache” instead).

As a CDN “caches” a source file/webpage, it is only suitable for “static” content which doesn’t change frequently (for example, images, Javascript, Cascading Style Sheets, downloads, etc). “Dynamic” content (i.e. content which changes frequently/upon each visit, files must still be served directly from the origin server, rather than via the CDN.

In MIDAS v4.18 we unofficially introduced support for serving static resources from a CDN (CloudFlare), and this has been automatically enabled for all MIDAS trials and for all new cloud-hosted customers since the start of April, whilst we closely monitored its impact and effectiveness.

As our CDN trials proved effective and exceeded our expectations, throughout May we’ve been engaged in a phased roll-out of the CDN for remaining cloud-hosted customers, and we’re pleased to announce that all cloud-hosted MIDAS systems now have CDN support enabled.

We’re currently seeing nearly 90% of all requests for static resources being served directly from CloudFlare’s global CDN network, and performance improvements and reduction in load times of customer’s hosted MIDAS systems of between 13% – 67%!

We’re sure you’ll appreciate these performance improvements, which are all part of our ongoing commitment to provide the best possible service for our customers! …and we’ve more improvements and enhancements in the pipeline too!
