If you’re familiar at all with Varnish, you know it improves content delivery performance by storing a copy of your content in cache, and every request thereafter is fulfilled by the cached content.
Both live and VoD streaming pose challenges ranging from latency to uptime - these issues pose no surprise but are also opportunities for getting creative in taking control of your own streaming infrastructure. At the heart of your solution is your CDN.
Hammering home the performance-performance-performance theme again and again, we’ve told the story of caching and protecting your backend many times. We’ve talked a lot about the ways in which Varnish Streaming Server lets you scale up to serve live and VoD streaming content no matter the demand on your platform. But a big part of this story is maximizing the power of the capacity you already have. Ultimately that is what caching is all about: you make copies of content you need to deliver so the copies are delivered, much faster than roundtrips to the backend could achieve while protecting the backend from overload.
Consulting firm Accenture has been discussing the importance of hyper-relevance in e-commerce and across online experiences. What is hyper-relevance? Essentially, it’s argued that we are moving beyond an age of personalization toward a more contextual and individual online (and in this case, shopping) experience. That is, personalization has not always performed well historically, whether because the company in question has the wrong or not enough information about the individual consumer to make personalization truly personal - or because the infrastructure powering sites that employ personalization has failed to deliver when the stakes were high.
