Microsoft Azure /ˈæʒər/ is a cloud computing platform and infrastructure, created by Microsoft, for building, deploying and managing applications and services through a global network of Microsoft-managed and Microsoft partner hosted datacenters. It provides both PaaS and IaaS services 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 1 February 2010 as Windows Azure, before being renamed to Microsoft Azure on 25 March 2014.[1]

Services

Websites

High density hosting of websites. Allows developers to build sites using ASP.NET, PHP, Node.js, or Python and can be deployed using FTP, Git, Mercurial or Team Foundation Server. This feature was announced in preview form in June 2012 at the Meet Microsoft Azure event.[5] Customers can create websites in PHP, ASP.NET, Node.js, or Python, or select from several open source applications from a gallery to deploy. This comprises one aspect of the Platform as a Service (PaaS) offerings for the Microsoft Azure Platform. It was renamed to Web Apps in April 2015. http://azure.microsoft.com/en-us/services/app-service/web/

Virtual machines

Virtual machines enable developers to migrate applications and infrastructure without changing existing code and can run both Windows Server and Linux virtual machines. Announced in preview form at the Meet Windows Azure event in June 2012[5] the Windows Azure Virtual Machines comprise the Infrastructure as a Service (IaaS) offering from Microsoft for their public cloud. Customers can create Virtual Machines, of which they have complete control, to run in the Microsoft Data Centers. As of the preview the Virtual Machines supported Windows Server 2008 and 2012 operating systems and a few distributions of Linux. The General Availability version of Virtual Machine was released in May 2013.

Cloud services

Azure network and computes deployment architecture

Microsoft's Platform as a Service (PaaS) environment can be used to create scalable applications and services. It supports multi-tier architectures and automated deployments. Previously named "Hosted Services", the Cloud Services for Windows Azure comprise one aspect of the PaaS offerings from the Windows Azure Platform. The Cloud Services are containers of hosted applications. These applications can be Internet-facing public web applications (such as web sites and e-commerce solutions), or they can be private processing engines for other work, such as processing orders or analyzing data.

Developers can write code for Cloud Services in a variety of different programming languages. There are specific software development kits (SDKs) provided by Microsoft for Python, Java, Node.js and .NET.[6] Other languages may have support through Open Source projects. Microsoft published the source code for their client libraries on GitHub.[7]

Compute

Batch

 ArrayList<String> lst = new ArrayList<String>();
       Collection<String> col = lst;
       lst.add("one" );
       lst.add("two" );
       lst.add("three");
       lst.remove(0);
       col.remove(0);
       System.out.println("Added three items, remove two, so 1 item to remain." );
       System.out.println("Number of elements is: " + lst.size());
       System.out.println("Number of elements is: " + col.size());

Microsoft Azure uses a specialized operating system, called Microsoft Azure, to run its "fabric layer": 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.

Scaling and reliability are controlled by the Microsoft Azure Fabric Controller 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.

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 which encapsulates the functions of interacting with the services. It also integrates with Microsoft Visual Studio, Git, and Eclipse.

    • Central US: Iowa
    • North-central US: Chicago, IL
    • South-central US: San Antonio, TX
    • West US: California
    • East US: Boydton, VA[20]
  • South America
    • Brazil: São Paulo State
  • Asia
    • China (North): Beijing
    • China (East): Shanghai
    • East Asia: Hong Kong
    • South East Asia: Singapore
  • Europe
  • Japan
    • Japan East: Saitama
    • Japan West: Osaka
  • Oceania [21][22]
    • Sydney, New South Wales
    • Melbourne, Victoria

The CDN nodes are located in 24 countries.[23][23][24]

As of July 2010, Microsoft had completed 6,000 installations of Azure in Ireland.[25] Executives at Microsoft hoped that this figure would rise to 100,000 installations by 2011.[25]

Construction of the $500 million facility required one million man-hours of work with a peak workforce of around 2,100 workers.[26] The facility, which began operating on 1 July 2009, currently covers 303,000 square feet (2.815 hectares), with 5.4 megawatts of critical power available. Over time, the data center is expandable to a total of 22.2 megawatts of critical power to support future growth.

Privacy

Microsoft has stated that, per the USA Patriot Act, the US government can have access to the data even if the hosted company is not American and the data resides outside the USA.[27] However, Microsoft Azure is compliant with the E.U. Data Protection Directive (95/46/EC). To manage privacy and security related concerns, Microsoft has created a Microsoft Azure Trust Center,[28] 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.[29] 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.[30]

Significant outages

Documented Microsoft Azure outages and service disruptions.
