What is Cloud Migration? Strategy, Processes & Benefits
Cloud migration is the process of moving business operations like data, applications, and other IT resources from a private server or local on-premises data center to the cloud computing environment that can be accessed anytime from anywhere.
Today, businesses are migrating to a cloud computing environment to improve their operational performance, agility, scalability, security, and user experience. Nearly 6 out of 10 businesses are moving their work to the cloud, and this trend is likely to continue in the coming years. At IDC Technologies, we are helping businesses make a transformative shift to the cloud.
Common Cloud Migration Strategies
There are five cloud migration strategies commonly known as 5Rs. Companies that want to migrate to the cloud should consider which migration strategy can fit their needs.
Rehosting is a strategy to shift an application from an on-premises host to a cloud service. In this situation, no big architectural change needs to be done to the servers and applications. They are simply taken from on-premises (the lift) and then moved to the cloud (the shift).Rehosting is suitable for companies that want to run quickly to the cloud without making extensive changes.
Replatforming is a migration strategy that is a variation of the rehosting approach and aims to optimize workloads and applications before moving them to the cloud.Replatforming allows companies to upversion applications while retaining the core application architecture. Upversioning involves rewriting application codes to make necessary changes to optimize its usage in the cloud.
Refactoring is a strategic approach requiring extensive changes to the legacy application architecture and a large portion of its codebase for an optimum fit into the cloud environment.Refactoring aims to enhance the existing application and implement features that are difficult to achieve with the current way the application is structured.
Repurchasing involves moving from on-premises to a cloud setup by scrapping existing licenses and starting up with newer ones to fit the cloud model. It is commonly used for adopting a SaaS-based version of an application that provides the same features, though it works in a cloud-based subscription model.
Retiring is astrategic approach that involves turning off parts of an organizational IT portfolio that are no longer useful or important to the business requirements.
Benefits of Cloud Migration
Moving to the cloud allows businesses to expand and grow effortlessly while working within the existing infrastructure.
Cloud migration can scale to support larger workloads and more users much more quickly and efficiently than on-premises infrastructure.
Cloud providers offer managed IT services that lower your operational costs and streamline maintenance tasks such as upgrades. Companies that migrate to the cloud spend significantly less on maintaining IT operations. They dedicate more resources to innovations like developing new products or improving existing products.
Migrating to the cloud improves performance and enhances the end-user experience. Websites and Applications hosted in the cloud can easily scale to serve more users and can run in geographical locations near end-users to reduce network latency.
Migrating to the cloud allows users to easily access cloud services and data from anywhere, whether employees or customers. This not only contributes to digital transformation, but enables an improved experience for customers, and provides employees with modern, flexible tools.
Why Choose the right cloud environment?
Identifying the right cloud environment that is suitable for your applications and IT infrastructure can help you achieve your business goals. Not all applications are cloud friendly. Some applications perform better on a private or hybrid cloud, while some need minor modifications.
There are three types of cloud services- public, private and hybrid. Every type of cloud environment has its own benefits and risks, and each one of them might be suitable depending on the criteria including organization’s size, type of data to be stored, and other business needs.
Analysing your architecture and carefully checking all your applications can help determine which application is suitable to migrate. Analysing your architecture and carefully checking all your applications can help determine which application is appropriate to migrate.
Moving your business operations to the cloud offers numerous benefits if properly executed. With the right expert by your side, like IDC Technologies, you get assistance to prepare all the resources and required assessments to make your cloud migration process successful.
