Strategies to make a workable Azure Cloud Migration

| | ,

Gone are the days when organizations kept a room filled with computers, local servers, and other devices to store their enterprise applications. The practice of on-premise app development is facing a major downfall as more and more businesses are leveraging cloud technology to develop and deploy their enterprise applications at a lower cost.

Microsoft Azure, a leading cloud computing platform, delivers all the bright benefits of the cloud to businesses, making it a preferable option.

A lot of businesses have started adopting the cloud to obtain higher application performance, scalability, and cost-efficiency. But, cloud migration comes with its challenges and risks, which can be avoided with careful planning and strategizing.

If you take the brighter side of migrating to Microsoft Azure, it provides your business with the opportunity to look at your IT infrastructure as a whole and streamline it as required. The process of cloud migration includes assessing each application and its environment to know whether it requires to be retired or updated to fit in the new environment.

Organizations that want to deploy their applications to the cloud utilize the following cloud migration checklist: (Step-by-Step Planning)

Assess on-premises resources

Some applications will be easy to migrate, while others might need more attention. During the initial planning phase of the migration process, organizations need to evaluate the interdependencies and environment of all the applications in their portfolio listings. The issues related to of migration might vary for each application, depending on their licensing arrangement and architecture.

Discover servers and applications

Your company portfolio probably has numerous applications running on a range of servers. With cloud migration assessment tools, organizations can prepare an inventory of virtual and physical servers in their respective environment. This will cover the wide array of details such as performance metrics and profile information about the organizations applications. All of this metadata and data about the servers will help make the cloud migration plan.

Map on-premises applications

Based on the inventory, organizations can map their servers to denote their on-premises applications. This will help identify dependencies or communication paths between servers to consider all the required components in the migration plan.

Evaluation of migration strategies

Get Azure migration strategy and resource recommendations for application servers utilizing cloud migration assessment tools. Organizations can also evaluate the power cost savings of Azure migration by calculating the entire cost of ownership for Azure platform, comparing it with the deployment cost of on-premises infrastructure.

Azure Migration

This phase assists the organizations with the selection of an appropriate migration approach for every set of applications. During this stage, enterprises will segregate apps that can be rehosted on the cloud from the applications that require some sort of modifications or complete rebuilding before shifting to the cloud.

Rehosting (Lift-and-Shift)

This approach is popularly known as “lift and shift” migration, allowing users to swiftly migrate to the cloud without any change in the existing current code. This can be utilized for applications that are architected to give the Azure IaaS scalability. This approach makes users reap the benefits of the cloud without adding the cost or risk associated with changing the code.

Rearchitect

This approach involves modernization of the applications, making it highly scalable, more resilient, and independently deployable. When applications need significant modifications in their capabilities, they require some significant revisions in their codebase to optimize the app architecture for the cloud platform. Azure services are utilized to accelerate this process and to scale and manage the applications quickly.

Replace

Replace is the last resort when a enterprise plans to migrate its operations to the cloud environments. This approach is adopted when an application needs to be built from scratch using cloud-native technologies. Using the Azure platform, organizations get a full-fledged environment for deployment in the cloud and application development, without the issue of dealing with the expense and complexity of middleware, software licensing, underlying app infrastructure, and other related resources. This approach offers businesses to manage their applications while Azure manages everything else.
