Cloud Migration is used for transferring applications, data, files, etc., to business-related elements to a cloud computing environment. It is not just easy to handle but decreases costs, is expandable, elegant, etc. Many cloud service providers are available like Azure, Google Cloud, AWS, etc. Handling physical hardware and networking on-site can increase the expense for information technology(IT) and network services, precisely when it's time for repair and replacement. For this, you need a proper cloud migration strategy. Keep reading to learn about the 6Rs of cloud migration.

What are the 6 Rs of Cloud Migration?

1. Re-host
Most companies prefer it is the most common way of migrating your data. It is the best option to re-host if you want to move your on-premises data or application without much effort.
Re-hosting may lead enterprises to re-architecting in the coming years once a cloud-based operation is in place.

2. Re-platform
Some legacy systems in well-established firms are too complex to be migrated to IaaS cloud architecture. To make legacy IT systems compatible with contemporary cloud technology, the programs are simulated using a virtual machine rather than changing their cores. It is the best alternative for businesses that cannot rebuild the IT legacy systems at the time of cloud migration, even though it can be expensive sometimes.

3. Re-factor/Re-architect
Re-architect means a redesign of your app in a more cloud-native way. It is the most evolved cloud migration approach.
Refactoring and re-architecture frequently increase agility, business continuity, general productivity, and teamwork. However, this method is typically used after an initial cloud architecture migration using one of the other strategies, such as rehosting, because it tends to be the most expensive.

4. Re-purchase
This entails switching to a cloud-first application and giving up your current software with a systematic cloud migration strategy. It reduces efforts and increases the speed of cloud migration. Replace antiquated systems with contemporary software and SaaS.

5. Retire
After application discovery, you know which application or data you require in the future. If you don't want to use them further, you can retire them, which means you can get rid of them as they are not required in the future.

6. Retain
Sometimes you don't want to migrate some elements of your environment, so those elements are retained. The IT aspect mostly prefers it because the migration of some applications costs too high, and your company can maintain more value using the app or service on the ground level.

Summing Up
cloud migration is comparatively easy as compared to an on-premises infrastructure, cloud computing can handle larger workloads and more users. In the cloud, we may store a lot of data, and cloud migration makes it simple to move that data around. Having a proper cloud migration strategy improves capability by allowing you to store as much data and applications as you want. Cloud-hosted applications and websites can easily be scaled to serve more users.
Also, cloud architecture is preferred by the well-settled organizations because it is not just easy to handle but also cost effective because physical storage is not easy to maintain and it is too high, flexible as you store a large amount of data in it, it improves the capability because it serves a large scale of population.
