Windows Azure for Cloud Computing.

1. Windows Azure
 Brief intro
 Windows Azure is a cloud-based operating system which enables running of business applications, services and workload in the cloud itself.
This works similar to traditional operating system functionality on any hardware platform and it allows applications to run in a virtual
environment by providing them indispensable physical hardware components and a set of services.
 Microsoft designed Azure to enable .NET professionals to strengthen their capability to develop ASP.NET websites, XML and WCF web
services.
 The main advantage of this is that it offers a distributed operating system in which we can build, test, and deploy applications without
worrying about the front-end interface. Moreover, we forget choices of hardware, capacity, server, location of disk space or the computer
names while using PaaS. The standard protocols such as REST and HTTP are associated with the interactions with this kind of virtual storage.
• History
 Microsoft Azure, commonly referred to as Azure, is a cloud computing service created by Microsoft for building, testing, deploying, and
managing applications and services through Microsoft-managed data centres. It provides software as a service (SAAS) platform as a services
(PAAS) and infrastructure as a services (IAAS) and supports many different programming language, tools, and frameworks, including both
Microsoft-specific and third-party software and systems. Azure is the largest commercial cloud vendor by revenue, although that designation
stems in part from the company's "power of incumbency in Office 365 Commercial and Microsoft 365," which may artificially inflate the
company's "pure cloud" revenue totals.

2.  Azure, announced at Microsoft's Professional Developers Conference (PDC) in October 2008, went by the internal project codename "Project
Red Dog", and formally released in February 2010, as Windows Azure before being renamed to Microsoft Azure on March 25, 2014.
• Versions
• Customers can now choose when their applications receive new operating system updates and patches by selecting which version of the
operating system their applications will run on in Windows Azure. Right now there is only one available operating system version (released on
December 17th, 2009), but new builds with the latest updates and patches will be released regularly. This new feature allows developers to
test their applications when new patches come out before upgrading their production deployments.
• To select an operating system version for your application, add the new osversion attribute to your service configuration file. The full list of
available operating system versions is maintained in the Configuring Operating System Versions topic in the Windows Azure MSDN
documentation.
•
its unique feature
• Iaas and PaaS
• Azure is the only cloud platform ranked as an industry leader by Gartner for both infrastructure-as-a-service and platform-as-a-service. It
supports various programming languages, tools and frameworks and lets you build, deploy and manage applications any way you like.

3. Hybrid Ready
 Some service providers make you choose between the public cloud and your data centre. Auer offers you enterprise proven hybrid cloud solution
like amazon web services that can help you expand your IT options without added complexity. The data storage, backup and recovery become
easier with Azure. Also, it becomes easy to build applications that span both cloud and on-premises.
 Open and Flexible
 Azure is open and flexible and supports any language, operating system, framework right from Windows to Linux, Oracle to SQL Server, C# to
Java. It brings the best of Linux and Windows ecosystems and enables you to build robust SharePoint applications and services that works well
with every device.
 Scalable and Economical
 Azure is quite scalable and matches every demand so you can pay for what you use.

4. Advantage
 Microsoft Azure offers high availabity.
 It offers you a strong security profile.
 Azure offers good scalability options.

 There are multiple redundancies in place to maintain data access.
 Azure allows you to use any framework, language, or tool.
 You can automate many of your repetitive tasks.
 You have access to a rich set of artificial intelligence services.

5. Disadvantage
 You’ll need to manage Azure to make it effect.
 You must have platform expertise available.
 Azure almost forces you to put all your eggs into one basket.
 Speed can be an issue for some businesses.
 The ease of access may be problematic for some businesses.

14. Conclusion
 Container-based solutions ultimately provide cost savings benefits. Containers are a solution to deployment problems because they remove the
friction caused by an absence of dependencies in production environments. By removing those issues, it improves Dev/Test, DevOps, and
production operations significantly.
 A Docker container is becoming the standard unit of deployment for any server-based application or service.
 For production environments, you should use an orchestrator (like Kubernetes) to host scalable containers–based applications.
 Azure VMs hosting containers are a fast and simple way to create small Dev/Test environments in the cloud.
 Azure SQL Database Managed Instance is recommended by default when migrating your relational databases from existing applications to Azure.
 Visual Studio 2017 and Image2Docker are basic tools for you to start modernizing your existing .NET applications with Windows Containers by
accelerating the getting started learning curve.
 When placing containerized applications in production you will always create or adopt a DevOps culture and DevOps tools for CI/CD pipelines, like
Azure DevOps Services or Jenkins.
 Microsoft Azure provides the most comprehensive and complete environment to modernize your existing .NET Framework applications with
Windows Containers, cloud infrastructure and PaaS services.
