Over the last decade, Cloud Computing has revolutionized itself from being an IT Solution to one of the most critical drivers of business success. According to Gartner, Cloud will become a Business necessity by 2028. Another report by IDC predicts that spending on the cloud will double between 2024 and 2028. This massive shift is fueled by businesses looking for a reliable, cost-effective, and scalable solution to keep their business ahead in the competitive market.
What is Cloud Migration?
Cloud migration involves migrating your IT infrastructure to the cloud, including your data, workloads, and applications. This allows your business to stay ahead of the competition by utilizing the several benefits and advantages that the cloud offers, such as:
- Cost-Effective: Having your data in the cloud means you don't have to worry about maintaining on-prem servers, etc. You only pay for the resources that you use.
- Easily Scalable: Cloud environments enable you to quickly scale up or down your resources depending on the requirements of your business. Enhanced Disaster Recovery: Disasters and the risk of downtime are always around the corner. In case of a cloud backup, you can instantly restore your data and continue your business if a disaster strikes.
- Managed Services: Many cloud providers offer Managed Cloud Services. This provides everything from migration and cost optimization to managing and scaling. This will allow you and your staff to focus on business-related stuff.
The 7Rs of Cloud Migration
As we know, Cloud Migration is a complex task, and proper planning and strategies are required before taking this crucial step. The 7Rs of Cloud Migration is a collection of strategies allowing businesses to plan and execute Cloud Migration according to their needs.
1. Rehost (Lift and Shift)
This is one of the simplest and fastest ways of making your applications cloud-native. The Rehost strategy involves migrating your data to the Cloud with minimal changes. It is suitable for businesses that require a quick move towards the cloud without making any changes. However, as minimal changes to your existing infrastructure were done, you may not utilize all the advantages of the cloud.
2. Replatform (Lift and Reshape)
With the Replatform strategy, you will have to make some slight modifications to your application to utilize the cloud features and are perfectly compatible. This can significantly improve the performance and optimization of your applications and can save you a lot of costs.
3. Refactor ( Re-architect )
If you want your application to utilize cloud-native capabilities fully, then you should opt for Refactoring. This strategy involves a complete overhaul of your application architecture and often involves containerization, microservices, and serverless computing. However, it is relatively complex and costly, but if you are looking for the best long-term performance, it will be a suitable option.
4. Repurchase ( Drop and Shop )
The organization replaces its existing applications with a cloud-native solution such as a SaaS solution in the Repurchase strategy. This will save you from migrating your legacy systems and offer a new start on the latest applications. Moreover, most Cloud Environments offer a pay-as-you-go model, allowing you to pay only for the resources you use.
5. Retire
Some applications, data, and workloads may be useless, have no business value, or just burden your infrastructure. The Retire strategy includes the termination or decommissioning of these workloads. This will help you to focus on cloud-native and modern applications that add value to your business.
6. Retain
Not all of the applications are suitable for migration to the cloud. These may include legacy applications that are either complex to migrate or inappropriate to go cloud-native. Some of the other reasons include regulatory requirements and security and compatibility issues. Hence, we refer to keeping these applications on-premises by Retain strategy as it will be more suitable and effective.
7. Relocate
The Relocate strategy involves migrating all your systems, such as virtual machines, on-premises platforms, Kubernetes, etc., to the cloud. This requires minor reconfiguration or rearchitecting of your existing infrastructure and is perfect for large-scale migrations.
