Because Microsoft Azure consists of widely varied resource and service offerings, its use cases are extremely diverse. Running virtual machines or containers in the cloud is one of the most popular uses for Microsoft Azure. These compute resources can host infrastructure components, such as domain name system (DNS) servers; Windows Server services, such as Internet Information Services (IIS); networking services such as firewalls; or third-party applications. Microsoft also supports the use of third-party operating systems, such as Linux.

Even simple applications can involve many interdependent cloud services and resources. Given the many factors involved in cloud service pricing, an organization should review and manage its cloud usage to minimize costs. Azure-native tools, such as Azure Cost Management, can help monitor, visualize and optimize cloud spending. It's also possible to use third-party tools, such as Cloudability or RightScale, along with emerging FinOps practices to manage Azure resource usage and associated costs.
Currently, there is a lack of standardization among cloud services and capabilities. Most cloud providers offer a broad suite of similar services, but no two cloud providers offer the same service in the exact same way. Cloud providers rely on APIs and other integrations to handle provisioning and services in a programmatic manner. Because each provider uses unique APIs, the onus is on users to accommodate differences between cloud providers. Thus, to migrate a workload from one cloud to another might require significant recoding of the application or rearchitecting of the cloud environment to support the workload. This makes it difficult for a business to use more than one public cloud provider when pursuing a multi-cloud strategy. Third-party cloud management tools can reduce some of these challenges.
Microsoft Azure, often referred to as Azure (/r, er/ AZH-r, AY-zhr, UK also /zjr, ezjr/ AZ-ure, AY-zure),[2][3][4] is a cloud computing platform run by Microsoft. It offers access, management, and the development of applications and services through global data centers. It also provides a range of capabilities, including software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). Microsoft Azure supports many programming languages, tools, and frameworks, including Microsoft-specific and third-party software and systems.
Launched in September 2020, Azure Orbital lets private industries and government agencies process satellite data quickly by connecting directly to cloud computing networks. Mobile cloud computing ground stations are also available to provide connectivity to remote locations without ground infrastructure. Third-party satellite systems, like SpaceX's Starlink and SES' O3b constellation, can be employed.[50][51]
According to Microsoft, using satellites to connect to cloud data centers may provide faster speeds than complex fiber routes. For online media, entertainment, or gaming activities, connecting from home to the cloud can involve longer routes with multiple hops. Through their experiments with Xbox Cloud, Microsoft has discovered that satellite connection is faster than terrestrial networks in certain parts of the world (including specific locations in the USA).[54]
1.1.4 CDN
A Content Delivery Network (CDN) avoids user latency problems by reducing the number of hops the request must make. This service provides a convenient way to minimize latency, because it caches data in various geographic locations across the globe. At a site, the Content Delivery Network (CDN) stores replicas of a BLOB closer to the clients that use it. Blobs typically store information such as videos that will be accessed from many locations. Hence, this mechanism speeds up the delivery of reputedly accessed content and improves performance.
1.2 AppFabric
Azure AppFabric provides a wide-ranging cloud middleware platform for developing, deploying and managing applications on the Windows Azure Platform. It allows the creation of combined access control and distributed messaging across clouds and enterprises and enables the linking of our existing applications to the cloud using secure connectivity across networks and geographic boundaries. Developers practice Windows Azure AppFabric to connect application pieces together, manage identity and access control, cache remote resources and create composite applications. Developers can build WCF-like services in Visual Studio .NET and publish endpoints to the cloud from within Visual Studio .NET design environment. The following diagram depicting the diverse components of AppFabric as in the following:
1.2.1 Access Control
The Access Control mechanism in the cloud employed to identity and access control to web applications and services resources using REST and the Web Resources Access Protocol (WRAP), while integrating with standards-based identity providers, including enterprise directories such as Active Directory (AD) and other web identities including Windows Live ID and Google. The client sends the request or claims to the public Access Control URL to access a specific remote application resource. Further, the Access Control service checks the input claims against the defined rules and produce the output claims and sends these claims in a secure token that the client application then sends to the remote application.
1.2.2 Caching
Caching is the most effective ways to improve performance to frequently accessed data in ASP.NET websites. Some applications repeatedly accesses the same information, caching therefore and making this information more readily accessible can make the application faster. In final words, the caching provisions in-memory, distributed and highly available application cache services for Windows Azure applications.
1.2.3 Service Bus
Via HTTP and the REST protocol, the Service Bus service allows secure connectivity and messaging experiences through which distributed applications can talk together. The Service Bus is of course, hosted in the cloud atmosphere, so any application with an internet connection can access it. You create a new service namespace using the portal itself to start exchanging messages via the Service Bus from any application and platform. The messages transmitted by service bus contains XML, graphics, binary data, text and streaming data content and moreover exposes classes to various programming environments using REST and HTTP to interact with the Service Bus nodes.
1.3 SQL Azure
The SQL Azure technology is employed into the cloud atmosphere to address the growing size and scale of the data that can address the primary data challenges associated with scalability, availability, security and manageability. Developers can access SQL Azure using a tabular data stream typical accessing on-premise SQL Server instances using SQL clients like ADO.NET, ADO.NET Entity Framework, LINQ and ODBC. Developers can create tables, indexes and views, use Stored Procedures and define triggers alike with SQL Server. Moreover, the significant benefits for SQL Azure is that the management requirements are significantly reduced because they need not worry about other operations, such as monitoring disk usage and servicing log files. The following figure depicts the various components of SQL Azure as in the following:
SQL Azure is the cloud-based technology solution to deal with relational and other types of data as part of the Windows Azure platform. Broadly, SQL Azure provides the following activities and key benefits:
Data Market offers a chance to expose their offerings to more customers using Microsoft's cloud platform. In simple words, Data Market provides a single place to find, buy and access a variety of commercial datasets.
Operating in Azure
The initial moment for Azure application development to the cloud is the Windows Azure Development portal that required a Windows Live ID to be access using a remote login utility such as Putty or RDP (mstsc.exe). The typical developer workflow involves the following procedure for creating or deploying an application in Windows Azure Platform.
Step 1: Create a Windows Azure account and login using Microsoft Live ID.
Step 2: Prepare the development fabric to create an application in the local cloud platform.
Step 3: Test the application in the development fabric.
Step 4: Package the application for cloud deployment.
Step 5: Test the application on Windows Azure in the cloud.
Step 6: Deploy the application in the production farm.
Microsoft is currently offering a free one month trial experience of Azure services. However, Microsoft doesn't offer free use of Azure services so far. Even as you create an account after buying the necessary Azure cloud services subscription and finally login into your Azure portal (manage.microsoftazure.com), you will be able to utilize the entire services including, Compute, Websites, Mobile and Data services, offered by Azure virtual operating system.
3. Security Concerns
The Windows Azure platform offers developers with on-demand compute and storage to host, scale and manage web applications on the cloud using Microsoft datacenters. Everything is managed so easily in the cloud; we don't need any hardware, software and configuration at all. But, the sole concern is data or resource security that is a nonnegotiable obligation for a cloud service. Business or sensitive data stored in the cloud needs to be encrypted not only during storage but also transport. Hence, it is mandatory to implement proper access control mechanisms to prohibit unauthorized access to the data and applications because critical data is one step away from getting in malicious hands. Secure channels across application domains in the cloud should be constructed into the cloud service infrastructure. If the environment and applications are not properly secured, any cloud platform could be compromised. However, IT architects are repeatedly concerned about the risks of cloud computing.
Conclusions
Cloud computing is the next generation of emerging technology where everything will be located in the cloud, just a naive device like tablet PC and mobile phone is equipped with an internet connection and a simple browser would be sufficient to get the taste of cloud computing. Executing applications in Azure clouds offer many advantages over the traditional way of running programs, like faster service deployment and massive savings upfront and easily manage business growth by scaling up or down the computing power and storage. Hence, this article provides a comprehensive tour of Windows Azure cloud computing. Moreover it has explained the various layers of the Windows Azure platform, including Windows Azure, data services, AppFabric and the marketplace. Finally, it discusses the life cycle of application development with real experiences of the Azure portal and examines various potential threats when operating in an Azure cloud environment in terms of sensitive data protection and authentication.
