How Azure Cloud Computing Works?

Azure Cloud Platform offers various cloud computing services including platform as a service (PaaS), infrastructure as a service (IaaS), and managed database service capabilities. Azure uses virtualization technology to provide cloud computing services to users.

The computer hardware is permanently or semi-permanently emulated in software. Through these emulation layers, software instructions are mapped to hardware instructions, so that the virtualized hardware can be executed in the software.

This virtualized hardware is provided to the end users from a physical server or data center. These data centers comprise server racks, containing server blades and network switches. Through these data servers, network connectivity, and a power distribution unit (PDU) are provided.

Moreover, some servers run fabric controllers to provide cloud services that allocate services, monitor the health of servers, and repair servers when they fail. The fabric controllers are connected to other servers running cloud orchestration software.

The cloud orchestration software or front end hosts the web services, RESTful APIs, and internal Azure databases, which are used for all functions in the cloud. Azure offers various servers and networking hardware for running a complex set of distributed applications.

By maintaining hardware in physical environments, Azure offers an orchestration of virtualized hardware and software to the users for developing and deploying applications effectively on the cloud.

Azure Cloud Migration Steps

Migrating your existing digital assets, including data, IT resources, workloads, or applications, to cloud is a simple and fast process with Azure. The following steps should be followed for a smooth on-premise to Azure cloud migration.

Step 1: Assessment & Planning

Before migration, define your strategy depending on migration triggers, business goals, and workload priorities. Decide what workloads need to be migrated to the cloud based on their expected growth and urgency. 

Comparing your total cost of ownership (TCO) for Azure with the on-premises deployment will give you a better idea. Discuss with your stakeholders how the cloud can help meet your organizational goals. 

Key considerations for assessment include: 

• Virtual network – Understand the requirements needed to create a virtual network having performance and stability at par or above the on-premise data center. For example, look at the number of subnets required and DNS management via Azure services.  
• Storage – The storage solution from Azure will depend on the nature of your data. The data that is rarely accessed should be stored in a slow and less expensive solution, in contrast to a fast and costly storage solution for frequently accessed data. Fast access means that number of operations per second is more. 
• Scalability – Azure has an autoscaling option for dynamic scaling as per requirements, but it needs careful cost modeling.  
• Virtual Machine Readiness Assessment Tool – You can use automated tools to understand physical or virtualized assets better. It provides a checklist for migration like sizing needs, workload-level cost estimates, and so on.  

Microsoft Assessment and Planning (MAP) Toolkit – To decide the right set of Microsoft technologies for migration, you can use the MAP toolkit. You receive detailed readiness reports for different environments like Windows 10, SQL Server 2014, Hyper-V, Office 365, Windows Server 2012, Microsoft Private Cloud Fast Track, and the like. 

Working with a service provider that offers support during and after the migration process should be considered. This will ensure that you have someone with the requisite cloud skillset and any issues are resolved timely. 

Once you have considered the cost, workload priorities, goals and timelines, procurement of resources, and various other factors, you can plan your migration project stepwise. 

Step 2: Migrating to Azure

During the migration process, you need to ensure that your IT team understands the fundamentals of Azure Cloud, the migration procedure, and the processes involved. This will help inefficient decision-making and working with Azure. Investing in training will be a good idea as the learning curve is simple and would not incur a high cost.   

Then, both in-house and outsourced IT teams can make faster decisions based on the assessment. Some of the considerations would include:   

• Whether a hybrid cloud solution is required   
• If there are machines with special system requirements that are incompatible with Azure VM sizing standards  
• If your workload needs an environment other than Azure (such as Microsoft’s Office 365)   
• Whether your team should run in traditional VMs or they should prefer containers or use of serverless functions      

Once you have made the decisions, use automated tools to move different workloads into their respective cloud services. To avoid governance-related problems, set up pre-configured landing zones. For instance, you will have to move web-based applications into Azure App Service. The migration phase in the lifecycle will follow an iterative approach.  

Step 3: Working with cloud

Azure provides complete transparency and control to businesses with real-time governance of the functioning of workloads on the cloud. You will be considering the migration of more processes and data into the cloud as your organization grows. This increases the need for optimization. Some factors that you should consider are:  

Performance targets: Check whether your migration goals are met and ensure that performance is better than the on-premises model. 

Cost: Monitor ways in which you can maximize the potential of Azure services at minimal costs. 

Next, plan how you can use your budget efficiently to get more features of Azure. 

Cloud environment needs management and governance on an ongoing basis. With the growth of cyber-attacks, you must pay proper attention to security too. So, you should focus on the following:  

• Security- Once the IT team knows the security posture of cloud applications, they must use security testing tools regularly and take actions against potential threats.   
• Data protection- With Azure Security Center, you can detect threats and prevent any harm from occurring to your organization across the environment. There are cloud backup and disaster recovery solutions to retain data. Azure Arc. Monitor simplifies managing your workloads via insights and analytic trends in real-time.  
• Monitoring- With tools such as NewRelic, Azure Traffic Manager, or AppDynamics, you can get performance reports of compute and data services in real-time. This keeps you updated and ensures that you take proper actions every time performance drops.  

You need to find and maintain standard and custom policies for your cloud subscription. This way, you can ensure that every app or workload in the cloud follows standard compliance.  

Which Companies Use Azure Cloud – Success Stories 

Some of the biggest companies in the world use Microsoft Azure’s assistance for their business processes. A few examples are discussed next.
