Heading into this summer, based only on the things we know will happen, we are likely to see the most web-traffic-intensive summer and fall ever with one major sports or political event happening after the other: European Championship Football is taking place in France in June and July, the Summer Olympic Games in Rio de Janeiro take place in August, and also during the summer, the US political party conventions, which officially name each party’s nominee, take place - to be followed later in the year by the US presidential election itself - probably one of the more dramatic ones in recent history.
Microservices emerged as a pattern some years ago. Initially it was an even fuzzier and more vague pattern than what it is today. One of Varnish Cache’s earliest supporters, Amedia, decided to redesign their infrastructure and went for a microservice pattern. They did something a bit different from what most others have done. They decided to stick Varnish in the middle of their microservices. Instead of having the microservices talk directly to each other they would connect them to Varnish and Varnish would proxy the connections.
Varnish Cache 4.0 is out! The Varnish team is thrilled and has just celebrated with a sip of bubbly. We are happy to announce this release to our community and the world. It includes some awesome enhancements for all of you to enjoy!
The beta is out. Varnish Cache 4.0 is just around the corner and we need a bit of help to cross the finishing line. The beta seems to be pretty solid, we've given it a fair beating in out testing facilities as well as some pretty rough production workload. The final production tests last week where done in cooperation with A-Media andRedpill Linpro and where quite encouraging. Varnish 4.0 ran stable on their workload happily chugging away 1300 requests a second.
If you have the option of giving Varnish Cache 4.0 a spin on your website, or giving it parts of your traffic we would be grateful. Crashes are very unlikely at this point, but just to be safe, we would recommend having a load balancer in front of the beta so you can gradually increase the load. If you need any help with converting the VCL, please let us know.
