This document provides information on scalable virtual machines (VMs) and VM scale sets in Microsoft Azure. It includes descriptions of VM scale sets, how they can be used to manage groups of identical VMs, and how they provide capabilities for deployment at scale, autoscale, load balancer integration, and other features. The document also compares unique attributes of VMs and VM scale sets. It provides examples of VM scale set templates and links to documentation and code samples for working with VM scale sets.

- 19. Data is stored.. Pros Cons OS Drive Self-contained, backed by data service Poor design in many scenarios. Storage limited, Temp drive Local, ephemeral, good for stateless scenarios. Not backed by storage RP. Storage limited. Azure Files Storage can be shared across clients. Perf/scale work ongoing. Limited scale and performance. Azure Blobs Data is a reliable service backed by storage. Existing apps need redesign. IOPS limits Azure Tables Data is a reliable service backed by storage. Simple data structure. App redesign. Remote source (e.g. DB) Data is a service separate from app infrastructure. Only suitable for a subset of apps. 3rd party shared storage e.g. Lustre Storage shared across clients. Scalable performance. Lustre is Linux only.
