Cloud is entitled to be crowned as the new paradigm in computing and shifting the business app on a cloud server is gathering steam today in every organisation. This has enabled innovation as well as created a new jargon of testing and migration which baffles many business owners. Here is a beginner’s guide to let you understand the nuances of cloud app migration. Cloud app definitely makes it faster to the markets and helps you immensely with your lead generation and buying you new customers and users.
Modulation in software testing
Choosing a cloud based infrastructure for your app translates into the challenges faced by developers in the differential handling of the app in a cloud based environment. Whether you are using cloud app migration or directly choosing app development in the cloud servers, you need to have a full grasp over the technical aspects of testing and developing. From tracking bugs to managing source code and from stress testing to deployment, you need to either be an expert at handling this or you need an expert to do this on your behalf. We offer repositories for cloud based code and can help you overcome all these challenges in a matter of time.
Testing is also one of the best ways to unveil application dependencies that might be less obvious to you. The biggest mistake is to try making the app completely functional as soon as the migration is accomplished. The best thing is to adopt a phased approach, which involves testing in each and every step.
Choosing the right cloud provider
Before going for cloud app migration, you must first decide whether you want it to be put up on a SaaS cloud server or IaaS. Checking for the bandwidth to avoid any pitfalls is also a great idea, for the time it takes to migrate app from X to Y might end up delaying your project. Don’t go blindly for the companies clamouring about seamless migration and consider the factors that can result in possible lock-ins.
Think about data encryption issues.
Pay attention to the proper networking in order to effectively connect source and target.
Be prepared to re- architect your application in case it does not fit well with the cloud environment. The notion for desirable environment might as well change as the server consolidation issues are bound to seep in.
If you choose developing the app on cloud instead of migrating it, then you may face restrictions on what tools and resources you can use and where you can publish them.
How to migrate app?
Practically, cloud app migration can be done in following 5 ways-
Rehost: In this you just need to redeploy application on to an environment with different hardware configuration, hence changing the application configuration too.
Refactor: This means you need to run your app on infrastructure provided by the cloud server.
Revise: Extending or modifying the existist code of app.
Rebuilding: you need to discard the old code and rebuild it on PaaS.
Replace: Completely discarding the application and using some other commercially available software.
