Migrating Legacy Apps to Cloud? Here Are 5 Easy Ways

Shifting to cloud might not seem to be the best option when it comes to legacy applications. Along with choosing a suitable service provider, you must also factor in safety, accessibility, workforce costs, etc. among other things. In this article at InformationWeek, Mark Goldin talks about 5 easy ways you can move your applications to cloud.

Cloud Migration Made Easy

It is a herculean task to move applications that you were working on for years. You must ensure that all the codes and the supporting architecture are moved without a glitch. Majority of the organizations opt for the lift-and-shift migration model. With this approach, your applications are up and ready for deployment in less time and without much errors. However, some locally hosted applications do not work well with cloud. Some do, but it costs you money. Moreover, you cannot upgrade your old codes with the cloud’s scalability feature. So, as a CIO, you must consider two aspects beforehand—whether it will be feasible for the company and be within budget. Following are some of the ways you can migrate your legacy applications.

  1. Vendor Selection: Search for prominent vendors and analyze if their features and services suit your purpose. Find out if the other market players and partners also prefer them. You can negotiate a deal with your existing service providers if they also offer cloud services. Compare the offerings of all the shortlisted vendors in terms of cost savings, support, setup, etc. Since the purpose is to shift legacy software, ask them for case studies and whitepapers to get an idea about their approach.
  2. Pairing with Service Providers: After zeroing in on the cloud vendors, you must pair them up with strong service providers. Apart from determining the relevance of their capabilities regarding the lift-and-shift model, ask them about their safety and agreement protocols. This will help you understand whether the service providers can cater to your company-based needs when they come on board.
  3. Connecting to the Service: After distributing the responsibilities to your cloud and service partners, focus on how you would integrate applications. Security and seamless coordination between in-house software and cloud should be your main concern now. Either you connect through ISPs and service providers or the previous telecom agencies.
  4. Test to Perfection: You need to devote at least 12 to 18 months to ideate and test before you start shifting. If your applications rely heavily on storage I/O, cloud will be a costly affair. Find out how much each workload will cost after the transfer in terms of memory and storage. Also, figure out if their backup, continuity, and disaster management are apt for your needs.
  5. Automation Comes to the Rescue: For the first few months, you might have to pay for overtimes and incentives. To minimize the possibility of cost overrun, automate processes wherever possible.
