This comprehensive guide about Microsoft Azure includes common use cases, technical limitations, and what to know before adopting the cloud computing platform.
The rise of cloud computing provides businesses the ability to quickly provision computing resources without the costly and laborious task of building data centers, and without the costs of running servers with unutilized capacity due to variable workloads.
Azure, Microsoft's cloud computing platform, launched in February 2010. In addition to traditional cloud offerings such as virtual machines, object storage, and content delivery networks (CDNs), Azure offers services that leverage proprietary Microsoft technologies. For example, RemoteApp allows for the deployment of Windows programs using a virtual machine, with clients on Windows, OS X, Android, or iOS using the program through a remote desktop connection. Azure also offers cloud-hosted versions of common enterprise Microsoft solutions, such as Active Directory and SQL Server.
This introduction to Microsoft's cloud platform will be updated periodically to keep IT leaders in the loop on new Azure services and ways in which they can be leveraged.

What is Microsoft Azure?
Microsoft Azure is a platform of interoperable cloud computing services, including open-source, standards-based technologies and proprietary solutions from Microsoft and other companies. Instead of building an on-premise server installation, or leasing physical servers from traditional data centers, Azure's billing structure is based on resource consumption, not reserved capacity. Pricing varies between different types of services, storage types, and the physical location from which your Azure instances are hosted.
For example, Storage pricing varies based on redundancy and distribution options. In the Central US region, hot locally redundant block blob storage (LRS-HOT), with 3 copies in one data center, starts at $0.0184 per GB. Geographically redundant storage (GRS-HOT), with 3 copies in one data center and 3 copies in a second geographically distant data center, starts at $0.0368 per GB. Read-Access GRS (RAGRS-HOT), which allows for read access at the second data center, starts at $0.046 per GB.
In addition to the aforementioned storage, virtual machine, CDN, and Windows-related services, Azure also offers a variety of other services.
- Azure IoT Suite offers various options for connecting and monitoring devices, as well as providing telemetry and analytics services.
- HDInsight is a customized Hadoop deployment.
- Azure Redis Cache is a managed version of the popular open-source Redis data structure server; Azure Cosmos DB is a hosted NoSQL database for specific use cases; and Azure Search is an OData-based managed search service.
- Azure Media Services offers cloud-based video playing, indexing, transcoding, and content protection services.
Microsoft, in coordination with hardware vendors such as Lenovo, Dell EMC, HP Enterprise, and Huawei, offers the Azure Stack appliance for use in hybrid cloud deployments. The Azure Stack appliance allows organizations to run Azure applications from the public Azure cloud while leveraging data hosted on-premise, as well as running the same services from the public Azure cloud on the Azure Stack platform.

Why does Microsoft Azure matter?
Azure, like other cloud service providers, offers the ability to instantly provision computing resources on demand. Compared to the onerous task of planning and building an on-site data center, along with the requisite hardware upgrades, maintenance costs, server cooling requirements, electricity costs, and use of floorspace—particularly for offices with associated real estate costs—the savings can add up very quickly.
The benefits of Azure extend beyond cost control, however. The task of administering certain technologies such as Windows Server, Active Directory, and SharePoint can be greatly eased with the combination of Azure and Office 365. This frees up IT staff to work on new projects, rather than spending time on general system upkeep.
Microsoft is aggressively courting organizations to move AI compute operations into Azure. At Microsoft Build 2018, the company highlighted its move of Project Brainwave—an FPGA-based deep learning system built for real-time AI—into the Azure cloud service as a preview. Microsoft is also previewing an edge computing version of Project Brainwave, which are on-premises servers that act as Azure IoT Edge devices. Microsoft claims that a single AI server can process 500 images per second, with the company charging 21 cents per million tasks.

Who does Microsoft Azure affect?
Organizations with an existing deployment of Microsoft technologies, particularly Windows Server and Active Directory, will find Azure to be a compelling upgrade. As Windows Server 2008 has reached the end of mainstream support, planning for a migration to cloud-hosted Azure services may be preferable to investments in new server hardware and Windows Server licenses.
As with any cloud service, the cost benefit is more real for cash-strapped startup organizations that lack the capital for provisioning hardware and associated costs of a traditional on-premise deployment, or leasing dedicated servers in a traditional data center. Because the billing structure of Azure is based on resources used, turning to the cloud allows a company's IT backbone to scale with corporate growth.

When was Microsoft Azure released?
The Azure platform was announced in October 2008, and reached general commercial availability in February 2010. Originally called Windows Azure, it was renamed to Microsoft Azure in July 2014. Additional service regions have been added continuously since the service was announced.
Azure Stack, the turnkey hybrid cloud solution offered by Microsoft and a number of hardware vendors, was first announced in May 2015. With the first technical preview in January 2016, organizations could use their own hardware as part of an Azure Stack deployment. This plan was subsequently walked back, with Microsoft requiring users to buy a prequalified Azure Stack system, under the belief that such offerings would perform better. Participating hardware vendors have continuously released new prequalified systems for use with Azure Stack.
Under Microsoft CEO Satya Nadella, Azure has expanded to include support for a variety of Linux distributions available in virtual machines on the Azure platform. Presently, CentOS, Clear Linux, CoreOS, Debian, Oracle Linux, Red Hat Enterprise Linux, SUSE Linux Enterprise, openSUSE, and Ubuntu are supported in the Azure platform, as well as FreeBSD. Additionally, Azure supports Docker images.
Microsoft and SAP have collaborated to make SAP's business software and services to run on Azure. At the Sapphire Now conference in 2018, Microsoft announced general availability of SAP HANA, noting that Azure offers "26 distinct SAP HANA offerings from 192 GB to 24 TB."

What services compete with Microsoft Azure?
One of the core strengths of Microsoft Azure is the ease of transition for organizations looking to migrate from other Microsoft products, such as SharePoint, or integrate tightly with an existing Windows deployment. For those organizations, Azure is likely the most compelling option for a seamless transition to the cloud. Additionally, Microsoft also heavily touts compliance certifications for government users, noting that Azure was the first public cloud platform with a FedRAMP P-ATO.
In terms of scale, Google, Amazon, and IBM are certainly capable of handling any amount of data or compute tasks you can generate. Amazon Web Services, much like Amazon itself, aims to be everything to everyone; as such, AWS has the most extensive portfolio of cloud services of any public cloud provider. Google Cloud Platform's core strengths are in machine learning, big data tools, and extensive container support. For IoT, the cloud provider market is still wide open, with tailored solutions available from GE Predix, Samsung's ARTIK Cloud, and ThingWorx.
