Before you deploy a product like Big Table, you should understand what your intended use is and make sure that the tools exist on Google Cloud Platform to support it. Second, you need to decide on the level of Engineering Support you expect to need from Google and lock that down before you proceed. You don't want to start with a LOB application only to discover that you get hamstrung due to a technical glitch with the platform.
We use Bigtable as the storage engine for large-scale, low-latency applications as well as throughput-intensive data processing and analytics. Big Table lets us scale up the computing power when we have a specific use and ratchet down when we don't.
