DESCRIPTION
As the basic components of cloud computing hit the mainstream, we’re seeing a second generation of application stack components emerge—cloud databases, load-balancers, messaging queues, caches, workers, and so on. They’re much more than just rented metal, and they’re what makes clouds much more than just on-demand hardware. In this session, we’ll look at the latest and greatest trends in the “cloud stack”, looking at where this technology is headed, why it holds so much promise, and what the major challenges and risks are.
