Azure File Share(PaaS)

Page 15: Azure IaaS

• Share data across VMs and applications• Multiple writers, multiple readers using standard file system semantics.

• Share settings throughout services• VMs can read settings and files from a common, shared location. These can be updated externally via REST.

•Dev/Test/Debug• Very useful to have a shared location for installing applications, setting up VMs, running tools, and keeping notes while developing, testing, and debugging cloud services.
