Build CDN
I think they should Build the CDN because they say they can offer something different and hopefully it turns out great for the best.

Re: Build CDN
Every provider has to determine whether bulding a CDN would be in their best interests (depending on their own network footprint, etc, etc). But it certainly looks like more CDN capabilities will be in demand in the foreseeable future, so it would likely benefit larger networks to obtain the ability somehow.
It may be quicker to go out and buy a Level3 than to build one... :P

@Adi that is surprising. Is that a reflection of some deep loyaltyto the one they use or a distrust of all others?

I think it could simply be a matter of geographic competition -- in some smaller areas, the use of multi-CDNs doesn't provide all that much redundancy or efficiency. Over a wider area, the benefits increase as CDN networks actually differ more significantly.

Re: Build CDN
mhh1fve - Yes, that's a factor as well. Global distributors will need multiple providers in some parts of the world since smaller, local players may offer better coverage than a large global CDN. It's always a balance between cost, management complexity, and end-user QoE.

As is almost everything.... Usually there's a "two out of three" restraint, too. eg. You want it done "fast, cheap, well" -- pick two.

Re: Build CDN
Ariella - I think it's to do with a couple of different things, but mostly I think it's ITV's own needs. They are a big online video service, by any standards, but perhaps not quite in the league of Sky or the BBC. And they are primarily an entertainment provider as opposed to live sports, so it's on-demand content, which is a bit easier. I think they are big enough that they can get their CDN provider to jump to their demands, but perhaps not quite big enough to swamp any one providers network. So they are trading the advantages of redundancy and multiple paths to the end user that multiple CDNs would give them, for the simplicity and control over their one provider -- who I'm sure will give them better pricing and more customization as long as they get all ITV's business.

Re: Build CDN
@Adi I see. Instead of following the "don't put all your eggs in one basket" kind of conventional wisdom, they're opting for the somewhat more rare, do put them all in one and then watch that basket.

Re: Build CDN
Ariella - Yes, that's a great way to describe it. It's one basket, so you get to decide how big, what shape, weave etc. Or at least, more so than if you had multiple baskets.

Ha! Well, it's not actually *that* rare these days. Netflix abandoned all of its own datacenters for AWS -- and created a ChaosMonkey project to help it figure out how to make sure that it could rely on AWS if semi-random things went wrong. So going with a single provider isn't crazy, and smaller companies do it all the time because they lack the resources for full redundancy -- and they just accept the risks as a cost of doing business with a profit margin goal.

Re: Build CDN
@mhhf1ve I suppose each company has its own calculus for the risk/benefit ratio and so can come to different conclusions about these things.

Yup. Full redundancy for backing up a service is a luxury for a lot of companies. As long as the service has greater than 99% or 99.9% uptime... usually customers will understand a few brief outages? Maybe instead of actually running a full backup, it's a better strategy to have backup *plans* that minimize downtime -- and if the downtime is less than 24hrs or so, then it's okay to operate without having an instantaneous fall back already running.

Re: Build CDN
mhhf1ve - There's certainly an explosion of traffic on them, but we seem to go round and round as an industry on whether its better to build your own or just work with one of the big guys.

The rise of OTT video services..
The decreasing costs of building/buying a CDN is also leading to the growth of video streaming services everywhere -- because they can be more reliable and offer decent video service to end users in a cost effective way. So now these video services just have to try to keep content licensing fees manageable.. :P

Re: The rise of OTT video services..
very true...though it seems like there are plateaus to this, ie, stages where stream counts rise so fast and so high, that delivery costs again become an issue, and streaming providers again start pushing for lower costs from their CDN.
Re: content costs - that'll be interesting to see. Not so much in the streaming space necessarily, but linear channels could see a major cull in coming years. That might bring down prices...or just thin the herd, and only the expensive survive.

Re: The rise of OTT video services..
The fate of linear video is going to be really interesting to see. Broadcasters seem to be holding onto their spectrum rights even though they could potentially make a lot of $$$ in an auction that gives up their last remaining licenses to OTA frequencies.... I wonder when the price will be high enough (and the OTT services cheap enough) for broadcasters to give up OTA spectrum rights and go completely virtual over IP...?
