Premium Storage account: The Azure Premium Storage service is the most recent storage offering from Microsoft, in which data are stored in Solid State Drives (SSDs) for better IO and throughput. Premium storage only supports Page Blobs. Use general-purpose v2 accounts instead when possible.  Storage accounts using the classic deployment model can still be created in some locations, and existing classic accounts continue to be supported.  All storage accounts are encrypted using Storage Service Encryption (SSE) for data at rest.  Archive storage and blob-level tiering only support block blobs. The Archive tier is available at the level of an individual blob only, not at the storage account level. 4Zone-redundant storage (ZRS) and geo-zone-redundant storage (GZRS/RA-GZRS) (preview) are available only for standard general-purpose V2, BlockBlobStorage, and FileStorage accounts in certain regions.  Premium performance for general-purpose v2 and general-purpose v1 accounts is available for disk and page blob only. Premium performance for block or append blobs are only available on BlockBlobStorage accounts. Premium performance for files is only available on FileStorage accounts.  Azure Data Lake Storage Gen2 is a set of capabilities dedicated to big data analytics, built on Azure Blob storage. Data Lake Storage Gen2 is only supported on General- purpose V2 storage accounts with Hierarchical namespace enabled. 11.6 SUMMARY  Computer systems have been steadily moving away from local storage to remote, server-based storage and processing—also known as the cloud. Consumers are affected too—we now stream video and music from servers rather than playing them from discs. By keeping your own documents and media in the cloud, you can enjoy anywhere-access and improve collaboration. We've rounded up the best cloud storage and file-sharing and file-syncing services to help you decide which are right for you.  These services provide seamless access to all your important data—Word docs, PDFs, spreadsheets, photos, and any other digital assets—from wherever you are. You no longer need to be sitting at your work PC to see your work files. With cloud syncing 200 CU IDOL SELF LEARNING MATERIAL (SLM)

you can get to them from your laptop at home, your smartphone on the go, or from your tablet on your couch. Using one of these services means no more having to email files to yourself or plug and unplug USB thumb drives.  If you don't yet have a service for storing and syncing your data in the cloud, you should seriously consider one. Which you choose depends on the kinds of files you store, how much security you need, whether you plan to collaborate with other people, and which devices you use to edit and access your files. It may also depend on your comfort level with computers in general. Most of these services are extremely user-friendly, while others offer advanced customization for more experienced techies. 11.7 KEY WORDS/ABBREVIATIONS  Virtual private data center: Resources grouped according to specific business objectives.  Standardized interfaces: Cloud services should have standardized APIs, which provide instructions on how two application or data sources can communicate with each other. A standardized interface lets the customer more easily link cloud services together.  Microsoft account (also called, MSA): Personal accounts that provide access to your consumer-oriented Microsoft products and cloud services, such as Outlook, OneDrive, Xbox LIVE, or Office 365. Your Microsoft account is created and stored in the Microsoft consumer identity account system that’s run by Microsoft.  Resource groups: Logical containers that you use to group related resources in a subscription. Each resource can exist in only one resource group. Resource groups allow for more granular grouping within a subscription, and are commonly used to represent a collection of assets required to support a workload, application, or specific function within a subscription  Service Administrator : This classic subscription administrator role enables you to manage all Azure resources, including access. This role has the equivalent access of a user who is assigned the Owner role at the subscription scope 201 CU IDOL SELF LEARNING MATERIAL (SLM)
