Pubmatic swaps AWS for OpenStack after public cloud hidden-cost horror show

The CFO was asking: "What do we need to do to get out of it?" And he was back to square one. Pubmatic needed hardware, network, management and control.

So the company set about stringently defining its requirements, decided to use its own existing hardware, centralise management, and it wanted strong vendor support. The integration, it was decided, would be as simple as possible.

Enter Platform 9, one of the earliest OpenStack service providers into the market. Gold said: "I explained my requirements, they were attentive. They allowed me to work on their roadmap, they were hardware agnostic - I didn't have to take down a single machine to bring it into their environment."

Pubmatic shifted to this OpenStack-based private cloud in its own data centres, and is now running a hybrid data centre where it largely runs on private cloud but relies on public for capacity spikes. And everything is managed from the same place.

"So, lesson learned," Gold lamented. "I experienced a lot of sleepless nights. And it's not black or white. Others will tell you public is the best thing that's ever happened."

"But remember to be realistic with your expectations and your estimates. I know that every project that's being given to me is going to start in a certain way, but will not end in the same way. There's always requirement change, add-ons, whatever it is.

"Always prepare yourself with enough of a buffer not to be in a situation where you said the project is going to be $50,000 a month and you end up with a $200,000 invoice, because you are the one who's responsible for that.

"Vendors like to talk about success stories in public cloud and there are very good ones. But they might not work for you."
