Migrating Legacy Apps to the Cloud
Switching to the cloud may not seem like the best option when it comes to legacy applications. In addition to choosing an appropriate service provider, you must also take into account security, accessibility, labor costs, etc., among other things. In this article we talks about 3 easy ways to move your applications to the cloud.
Migrating to the cloud is easier
It may seem like a daunting task to move applications that you have been working on for years. You must ensure that all codes and support architecture move smoothly. Most organizations opt for the migration model of promotion and change. With this approach, your applications are ready and ready for implementation in less time and without many errors. However, some locally hosted applications do not work well with the cloud. Some do it, but it costs you money. Also, you can not update your old codes with the scalability feature of the cloud. Therefore, as a CIO, you must take into account two aspects in advance: if it will be feasible for the company and will be within the budget. The following are some of the ways you can migrate your legacy applications.
Selection of suppliers: search for outstanding suppliers and analyze if their characteristics and services adapt to their purpose. Find out if the other market players and partners also prefer them. You can negotiate an agreement with your existing service providers if they also offer services in the cloud. Compare the offers of all the preselected suppliers in terms of cost savings, support, configuration, etc. Since the purpose is to change the legacy software, request case studies and technical documents to get an idea about its approach.
Pairing with service providers: After concentrating on cloud providers, you must match them with solid service providers. In addition to determining the relevance of their capabilities with respect to the elevation and change model, ask them about their security and agreement protocols. This will help you understand if service providers can meet the needs of your company when they join.
Connect to the service: After distributing the responsibilities to your service and cloud partners, focus on how you would integrate the applications. The security and perfect coordination between the internal software and the cloud should be your main concern now. Or connect through ISP and service providers or previous telecommunication agencies.
Try to perfection: you must devote at least 12 to 18 months to devise and try before you start to change position. If your applications depend heavily on storage I / O, the cloud will be expensive. Find out how much each workload will cost after the transfer in terms of memory and storage. Also, find out if your backup, continuity and disaster management are suitable for your needs.
Automation comes to the rescue: during the first months, you may have to pay for overtime and incentives. To minimize the possibility of cost overruns, automate processes whenever possible.
