Moving your legacy applications to the modern cloud with Microsoft Azure
Legacy applications can be a headache for organizations undergoing a digital transformation. Software developed on out-of-date platforms using older programming tools can be inflexible and difficult to change. How can organizations modernize existing applications that are still critical to the business?
Levels of Legacy Application Modernization with Azure
Although there is no single or one-size-fits-all strategy to migrate the legacy applications to the cloud, the right migration strategy depends on your organization’s goals, how your applications will align to them, and what value the applications bring to your business.
- Cloud Infrastructure-based Applications migrate or rehost existing on-premises applications to the Infrastructure as a Service (IaaS) platform. The apps will have almost the same composition as before, but they can now be able to deploy to VMs in the cloud. This form of migration is typically known as “Lift & Shift.”
- Cloud Optimized Applications help organizations gain additional benefits even without altering or the significantly rearchitecting code. You can run your app with modern cloud technologies such as containers or through other cloud-managed services. You can also deploy the containers on PaaS or IaaS to databases, monitoring, cache as a service, and CI/CD (continuous integration/continuous deployment) pipelines.
The ultimate goal?Cloud-Native Applications are the ultimate cloud goal, as they are purpose built for the cloud model. These applications—built and deployed in a rapid cadence by small, dedicated feature teams to a platform that offers easy scale-out and hardware decoupling—provide organizations with greater agility, resilience, and portability across cloud environments.
