Microsoft Azure "/ˈæʒər/ is a "cloud computing service created by "Microsoft for building, deploying, and managing applications and services through a global network of Microsoft-managed "data centers. It provides "software as a service, "platform as a service and "infrastructure as a service and supports many different "programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems.

Azure was announced in October 2008 and released on February 1, 2010 as Windows Azure, before being renamed to Microsoft Azure on March 25, 2014.[1][2]

Services[edit]

Microsoft lists over 600 Azure services,[3] of which some are covered below:

Compute[edit]

Mobile services[edit]

Storage services[edit]

Data management[edit]

Messaging[edit]

The Microsoft Azure Service Bus allows applications running on Azure premises or off premises devices to communicate with Azure. This helps to build scalable and reliable applications in a "service-oriented architecture (SOA). The Azure service bus supports four different types of communication mechanisms:["citation needed]

Media services[edit]

A PaaS offering that can be used for encoding, "content protection, streaming, or "analytics.["citation needed]

CDN[edit]

A global "content delivery network (CDN) for audio, video, applications, images, and other static files. Can be used to cache static assets of websites geographically closer to users to increase performance. The network can be managed by a REST based HTTP API.["citation needed]

Azure has 30 point of presence locations worldwide (also known as Edge locations) as of December, 2016.[12]

Developer[edit]

Management[edit]

Machine Learning[edit]

Regions[edit]

Azure is generally available in 38 regions around the world.[14]

Design[edit]

Microsoft Azure uses a specialized operating system, called Microsoft Azure, to run its "fabric layer":["citation needed] a cluster hosted at Microsoft's data centers that manages computing and storage resources of the computers and provisions the resources (or a subset of them) to applications running on top of Microsoft Azure. Microsoft Azure has been described as a "cloud layer" on top of a number of Windows Server systems, which use Windows Server 2008 and a customized version of "Hyper-V, known as the Microsoft Azure Hypervisor to provide virtualization of services.["citation needed]

Scaling and reliability are controlled by the Microsoft Azure Fabric Controller["citation needed] so the services and environment do not crash, if one of the servers crashes within the Microsoft "data center and provides the management of the user's Web application like memory resources and load balancing.["citation needed]

Azure provides an "API built on "REST, "HTTP, and "XML that allows a developer to interact with the services provided by Microsoft Azure. Microsoft also provides a client-side managed class library that encapsulates the functions of interacting with the services. It also integrates with "Microsoft Visual Studio, "Git, and "Eclipse.["citation needed]

In addition to interacting with services via API, users can manage Azure services using the Web-based Azure Portal, which reached General Availability in December 2015.[15] The portal allows users to browse active resources, modify settings, launch new resources, and view basic monitoring data from active virtual machines and services. More advanced Azure management services are available. [16]

Deployment models[edit]

Microsoft Azure offers two deployment models for cloud resources: the "classic" deployment model and the Azure Resource Manager.[17] In the classic model, each Azure resource (virtual machine, SQL database, etc.) was managed individually. The Azure Resource Manager, introduced in 2014,[17] enables users to create groups of related services so that closely coupled resources can be deployed, managed, and monitored together.[18]

Privacy[edit]

Microsoft has stated that, per the "USA Patriot Act, the US government could have access to the data even if the hosted company is not American and the data resides outside the USA.[23] However, Microsoft Azure is compliant with the "E.U. Data Protection Directive (95/46/EC)[24][25]["contradictory]. To manage privacy and security-related concerns, Microsoft has created a Microsoft Azure Trust Center,[26] and Microsoft Azure has several of its services compliant with several compliance programs including "ISO 27001:2005 and "HIPAA. A full and current listing can be found on the Microsoft Azure Trust Center Compliance page.[27] Of special note, Microsoft Azure has been granted JAB Provisional Authority to Operate (P-ATO) from the U.S. government in accordance with guidelines spelled out under the "Federal Risk and Authorization Management Program (FedRAMP), a U.S. government program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud services used by the federal government.[28]

Significant outages[edit]

Documented Microsoft Azure outages and service disruptions.
