With the development of cloud, organizations began questioning the shrewdness of having committed or shared data centres. Overseeing data centres is an undeniable task in itself, which was not the center competency of the greater part of the associations maintaining them. As the expression goes, things are best left to specialists. Distributed storage gave organizations storage solutions without contributing time, resources and money in setting up, keeping up and upgrading their very own storage facilities. The key driving factors in opting for cloud migration include: Minimum upgradation costs, Faster response time, Reduced operational risks, Focus on product development, Reduced infrastructure establishment and maintenance costs etc. You can also know multi-cloud strategy at- Everything you should know about Multi-cloud strategy.
What is Cloud Migration?
A cloud migration is when a company moves some or all of its data center capabilities into the cloud. It is carried out to run on the cloud-based infrastructure provided by a cloud service provider such as AWS and Azure.
Main phases of cloud migration process-
Cloud movement has its very own complexity which can winding control if not done appropriately. The procedures for cloud migration must be set up before the first step towards moving IT portfolio to the cloud. Any such procedure ought to have these five overall stages.
Phase 1: planning-
Cloud migration should never be undertaken just because it is the most recent innovative trend and specialists accept that it minimizes costs significantly, without influencing the quality of products or services. Associations need to build their own case for cloud migration relying upon their unique business and IT portfolio. Having a sound business strategy for cloud migration empowers teams associated with the genuine procedure to prepare themselves. It expedites every stakeholder on a similar page and the cloud migration procedure runs easily till the end.
This is necessary because the cloud migration is is a long term process but a long drawn one depending upon the number of applications to be migrated, their architecture, how old they are etc.
Phase 2: Portfolio discovery and planning-
When everyone concerned concurs that cloud migration should be attempted, full portfolio investigation of applications, environments, interdependencies and desired business results must be finished. Businesses also need to build their own migration procedures as indicated by their business objectives and needs. Making a list of portfolios and its qualities make it simpler in the later stages to choose which applications should be migrated and how. Migration will undoubtedly influence your business, so it should be painstakingly arranged. Complete portfolio investigation empowers migration teams to draw a cloud migration methodology most appropriate for every situation.
Phase 3 / Phase 4: Designing, migrating, and validating applications-
Every application must be designed, migrated and approved in accordance with the cloud migration procedure. This is an iterative phase as a nonstop improvement approach must be received. Teams must gain from the migration of every application and enhance the migration procedure for the following one appropriately.
Phase 5: Modern operating model-
When a couple of applications are migrated to the cloud, the cloud turns into your new operating environment. Admirably, you should already have an operating model in place but for all intents and purposes you can learn from the initial some migrations to develop one. You have to enhance this model to accomplish your business objectives, turn off the old frameworks and move towards the modern operating model. Cloud relocation is impossible in a day, and this is as it should be. As applications get added to the cloud condition, you have to quicken the migration process and continue tweaking it to accomplish greatest output. On the off chance that you attempt to upgrade the environment in the wake of moving every of the applications to the cloud, it will end up being a near impossible task and the ideal result will likewise not be accomplished.
6 Recommended strategies for cloud migration-
Rehosting is ordinarily embraced if there should be an occurrence of enormous legacy migrations where association needs to scale the migration procedure rapidly. Rehosting makes it simpler to embrace new architecture and improve the application to exploit cloud technology. This is because moving to the cloud is generally the hardest piece of the entire procedure. After the movement is finished, everything else can be dealt with by the tools provided by cloud hosting or cloud migration partners. Most cloud facilitating partners give the essential tools to automatic rehosting of your applications.
2. Replat form-
This includes tweaking the current applications to exploit cloud hosting optimizations without changing the current architecture. This is typically done by moving to tools and services accessible to you after the migration. Exploiting cloud services empowers you to concentrate on results instead of how those results are really accomplished.
Legacy applications may have an alternate or old arrangement of frameworks and architecture when compared with cloud-hosted applications. Numerous associations overhaul or supplant the present one with current, cloud compatible ones. Repurchasing could end up being a significant investment in the cloud migration process. Hence, it must be embraced after due constancy. In any case, a cautious analysis uncovers that the expense of repurchasing is usually more than recovered rapidly.
4. Refactor / Re-Architect-
The way of developing non-cloud hosted apps is different from cloud-hosted ones. Sometimes associations may choose to update, alter or totally change application architecture to include cloud-native highlights that help scale and improve execution. A money saving advantage analysis must be attempted before any such choice because that rearchitecting can be costly.
While migrating to the cloud, associations get to stock of their applications and distinguish the ones that are not utilized at all or extremely less as often as possible. They may, thus, choose to resign these applications and concentrate rather on the more frequently utilized ones. Resigning the old or unused applications aides in minimizing expense since cloud hosting works on the compensation as you use basis.
During making arrangements for movement, you may also choose to hold a portion of the applications in the old condition itself. This could be a direct result of any of these reasons:
- Exceptionally complex for cloud migration. When you gain experience of cloud migration, you may choose to migrate them later.
- Extremely critical to the business. Migration may affect the availability and functionality of applications anyway little the span. Organizations may decide not to migrate applications that are critical to the point that they can’t manage the cost of any personal time. When different applications are running in the cloud, a substitute technique can be concocted for migrating these critical applications.
- Recently upgraded application. On account of uses that were recently upgraded, associations may decide not to put resources into them again unexpectedly early.
Best practices for a successful cloud migration-
For cloud solution, none of the size fits all solution is accessible. The technique and approach rely on numerous factors like application architecture, application criticality, business objectives, resources accessible, and so forth. Let us see the best practices for successful cloud migration.

Setting up cloud architecture and access management team is a smart thought to screen the cloud migration progress.
2. Cloud migration stage-
With regards to genuine cloud migration, it is a smart choice to begin smart and basic. Start with a solitary small application that is easy to migrate. As you gain experience in migration you can begin migrating the more complex or larger applications. Cloud migration is a transformational phase for the entire organization and every one of the individuals included should approach it all things considered. Look towards robotizing however many procedures as could reasonably be expected and proceed with automation culture even after the migration procedure is finished. This will allow you to take maximum benefit of cloud hosting. To make things simpler for you, your team and your clients, exploit completely managed services provided by cloud hosting partner. The increase in expense, assuming any, will be more than remunerated by the time and effort you will save.
Post cloud migration stage-
After the cloud migration of all the applications is finished, you should advance DevOps and Agile mindset inside the teams to concentrate on accomplishing business objectives. Most of the cloud hosting suppliers have cloud native tools and cloud support services for observing and maintaining applications. Exploit these tools and services, and don’t avoid building up your very own customized solutions dependent on them. Upskilling and retraining the colleagues must go on through the migration procedure however it turns out to be significantly important in the post cloud migration stage.
