App and Web Services Migration Approach to Azure

Azure - Azure, Cloud

With many enterprises, be it traditional or new-age, working to align their IT initiatives with their Businesses have made ‘cloud’ an integral part of the strategy. To draw maximum results, the applications and databases should ideally run on the most modern cloud infrastructure, like Microsoft Azure. In this article/approach document, we will try to elucidate what a modern cloud infrastructure is and our migration methodology.

So, what’s a modern cloud infrastructure?

  • Enables dynamic provisioning of computing resources with a few mouse clicks
  • Regularly upgraded hardware with an agile architecture to meet not only today’s needs but also tomorrow’s
  • Best-in-class security
  • Flexible pricing models

Why Azure?

  • Scale: Global businesses or a high transaction business from a particular geography, they can count on Azure for their infrastructure to scale to match their requirement – scale with elasticity.
  • Speed & Ease: Enterprises should be in a position to leverage the huge computing power of the cloud with a few clicks and offer the best experience to the users.
  • Performance: Microsoft Azure runs a worldwide network of datacenters and regularly upgrades the hardware. Having the best hardware leads to reduced latency and better performance
  • Security: Protecting data, apps and infrastructure is one of the top priorities for enterprises. Azure offers the right set of policies, controls, and technologies to ensure a secure environment.
  • Reliability: Customers can be assured of High Availability & Disaster Recovery at an optimal cost as data can be mirrored within the cloud infrastructure.

Overall Migration Approach:

Microsoft Azure’s Web Apps and its tools have made it easier for enterprises to move their websites and applications with ease. To further smoothen the process, we are suggesting the following approach:

    • 1. Migration Strategy & Methodology
      1. Analyze your priorities:
        • What triggered this request for migration?
        • What is the business outcome expected?
        • Work-load priorities
        • Total Cost of Ownership
      2. Choosing the right option:
        • X as a Service (X-aaS): Based on the business goals, the enterprise team has to select between Platform as a Service (PaaS) or Infrastructure as a Service (IaaS)
        • While IaaS provides virtualized hardware, PaaS offers the organizations, cloud platform to run their apps, databases on the most modern hardware
      3. Cross-functional teams (CFT):
        • For a smooth execution, stakeholders from Finance, Business and IT have to come together to form this CFT
    • 2. App Migration Approach
      1. Step 1: Analysis & Strategy
        • Understanding the customer’s business requirement & applications’ role
        • Apps’ performance, architecture in the current environment (on-premise)
        • Understanding the data flow (input & output & interdependencies)
        • Choosing the right service (Infra or Platform as a service)
        • Selecting the right cloud computing plan including the database & storage
      2. Step 2: App Migration
        • Pre-migration checklist and sign-off
        • Prepping the App to be compatible with Azure
        • Porting and Migration of App to Azure
      3. Step 3: Storage Migration
        • Pre-migration checklist of current databases (DB) and sign-off
        • Prepping the databases to be compatible with Azure
        • Migration of SQL or other DBs to Azure Store
    • 3. Manage, Secure & Scale

After migration, for the best performance enterprises are recommended to utilize the tools like Azure Arc, Azure Security center.

    1. Manage:Azure Arc helps you manage workloads across multiple environments. This enables the admins to monitor the performance in real-time.
    2. Secure: Detect & respond to threats to your work environment using Azure Security Center and Azure Sentinel, with full visibility.
    3. Scale: Constantly analyze workloads and based on the performance matrix, it is recommended to arrive at the right mix of standard and custom policies to govern & scale the cloud environment. This will not only ensure high availability but also offer the best experience.
