Cloud is becoming an important ingredient for any business to make a headway on the road to success. It enables SMBs to large conglomerates to work more efficiently resulting in higher productivity and revenues.
As per IDC Cloud view 2016 survey “58% of all organizations surveyed are embracing cloud, using private or public cloud for more than one or two small apps or workloads, up from 24% 14 months ago.”
Nowadays, most organizations go for bulk application migration to cloud for various advantages provided by the cloud hosting providers in India and across the globe.
When we are talking about migration to cloud, we have to take care about two important aspects “what” and “how” as it is not a cake walk and we have to manage all the things i.e. from the selection of the cloud service provider till the final step.
You need to choose according to your business requirements – public cloud services or private cloud hosting services. Now, instead of beating around the bush, let’s understand – how to migrate any application to cloud?
Here’s the step by step guide for migration of any application or website to cloud–
- Evaluate your application needs
The process of migration begins with the evaluation of the application needs to make sure that it is feasible to migrate and also the assessment regarding the cloud model, security and compliance needs.
“When the CIO issues the simple directive: ‘Move some applications to the cloud’, architects face bewildering choices about how to do this, and their decision must consider an organization’s requirements, evaluation criteria, and architecture principles,” said Richard Watson, research director at Gartner. “However, no alternative offers a silver bullet: all require architects to understand application migration from multiple perspectives and criteria, such as IT staff skills, the value of existing investments, and application architecture.”
Here are the migration strategies suggested by Gartner:
- Rehost: Redeploy the application on a different hardware environment and on a new infrastructure configuration, without modifying its architecture.
- Refactor: Run applications on PaaS (Platform as a service) so that developers can reuse frameworks, languages, and containers in which they have invested.
- Revise: It involves modifying the existing application code base to support legacy modernization requirements. It allows the enterprises to optimize the application according to the providers’ infrastructure.
- Rebuild: It involves the complete re-architecture of the existing application to fit the cloud environment. This rebuilding gives the ability to access innovative features on the provider’s platform.
- Replace: It includes the complete discard of the existing application and building anew on SaaS.
- Analyze the compatibility of the application
The second important factor is the compatibility of the application across different browsers and OS. You can detect the layout problems with the help of Browsera, an online tool that runs on cloud infrastructure.
The Migration Assistant checks various key elements or blocking issues which may prevent a successful migration. For e.g. if you want to migrate your website to Azure, you have to take care of Port bindings, Global assembly cache, Authentication, Application pools, COM components and so on.
- Planning is essential for the migration
It would be a futile move if you migrate unmanaged data. Thus, planning plays an important role to decide what, where and how to migrate. It’s good if you migrate the more demanding applications first like development and testing apps, so cloud would certainly fit their needs. Also, you have to take care about the ROI and the SLA offered by those providing cloud migration services.
- Test your application in the cloud
You should ask yourself: “How to automate processes so that management and running of my applications in the cloud become easier?”
As cloud gives you the ability to create a clone environment, you can check your application and its performance in it. So, after deciding about the new cloud ecosystem, you can test how your application to be migrated will adapt to the new environment.
- Board the plane
The final move is to implement the migration after making all initial assessments. Following migration, check the performance of your application in the cloud regularly. Is it better than your previous hosting platform? Are you getting reduced total cost of ownership (TCO)?
Last but not the least, you should never forget to explore the resource bank and keep experimenting to grow your business exponentially so as to make a substantial place in the market.
Follow the best practices for migration of your website/application to cloud to make sure that it will be worthful.
