The future of streaming - and of the internet itself - is video. We've been saying it repeatedly for a long time, and anecdotally, we see companies and organizations across industries adopting more video and using it in new, creative ways. Video has saturated the landscape.
Closing out the days of 2017, I asked some of my colleagues for their predictions heading into 2018 - where is technology going? Which current trends will continue toward the mainstream, and which will fizzle out as unsustainable? Are some buzz terms, such as edge computing, figuring into the future, or are they mere building blocks to bigger and better things?
Our recent webinar on live and OTT/on-demand video streaming brought up some frequently asked questions about using Varnish for streaming. I don’t think it’s an understatement to say that streaming - and enabling reliable, high-performance streaming - is a hot topic… so we’re going to address some of these questions here.
There's a recurring discussion I get myself into, and it goes roughly like this:
- I want to stream live video, what kind of machine, and how many of them do I need?
- It depends.
- Depends on what?
- Math! Also, numbers!
- Joking, can you tell me <list of characteristics>
- <provides value>
- <performs black magic>. The answer to your question is <scarily accurate values>!
Obviously, it doesn't go "exactly" like this, but the goal of this post is going to be largely about boring math, so it sounds cooler if we say I'll be talking about black magic, right?
Let's open the grimoires and see how we can answer this sizing question!
