Biography: Mahesh Paolini-Subramanya
Mahesh Paolini-Subramanya is a V.P. of R&D at Ubiquiti Networks - a manufacturer of disruptive technology platforms for emerging markets. He has been involved in ‘Internet Stuff’ since Day Zero (remember Gopher?), and has spent the recent past building out Erlang-based massively concurrent Cloud Services and VoIP platforms.
He has the - dubious - honor of being involved in creating the first web/e-commerce system, the first Java based financial services platform, as well as the first Erlang-based cloud PBX, three products he may never live down.
He was previously the CTO of Vocalocity after its merger with Aptela(where he was a founder and CTO). Before that, he was V.P. of Development at Neoglyphics Inc, and CTO of Proxicom where he also led the Technology practice. He holds a B. Tech from the Indian Institute of Technology - Kanpur, and an M.S. in Electrical Engineering from the University of Notre Dame.
Presentation: TweetCan your Service survive a Cold Start? (Sadly - probably not)
Cold-starting a cloud service is a lot trickier than it sounds. It can include sequencing system services, warming caches, and preloading accounts, and this before you even get to the point where you need to throttle the firehouse of API calls from your customers - all of whom are now frantically hitting your system. Even worse, the last time you actually did a cold-start was a few order of user-magnitude ago, and even then at 2AM on Xmas morning. You don't know it yet, but that process Will Just Not Work at 2PM on a cold february wednesday.
Join me as I take you through the world of queueing theory, back-pressure, load-ramping, and tactical avoidance, things that most people should be architecting into their services, but aren't.
Talk objectives
Hammer home the point that it isn't enough to build your system so that it can't fail. You need to develop it so that you can recover - from scratch - when it does fail!
Target audience
Anyone that has built a "cloud" service, or, heck, anyone that uses a hosted service...
