This week, Chris and Martin discuss the merits of building virtual SANs in the public cloud. Vendors including Silk and Pure Storage now offer virtual storage “appliances” built from virtual instances and cloud storage. Why are these solutions necessary, when the public cloud providers have plenty of high-performance block and file storage offerings? The discussion looks at the why and how of these types of solutions as well as the implications and the lock-in they could represent.
