What is Application modernization?
Application modernization is the process of updating and improving legacy software applications to leverage the latest technologies and cloud capabilities. Azure cloud provides a variety of services that can help organizations to modernize their applications.
What are the steps that are involved in the journey?
The first step in the application modernization journey is to assess the existing applications and identify the areas that need improvement. Azure provides tools such as Azure Migrate and Azure Advisor to help organizations evaluate their current applications and identify areas for modernization.
Once the assessment is complete, the next step is to choose the right modernization approach. Azure offers several options such as rehost, refactor, rearchitect, rebuild, and replace. Typically known as the 5Rs of Application modernization. Organizations can choose the approach that best suits their specific needs and goals.
What are the 5Rs of application modernization?
Rehosting involves moving an existing application to Azure with minimal changes. This approach can help organizations quickly migrate their applications to the cloud, but it does not provide the full benefits of cloud-native capabilities.
Refactoring involves making minor changes to the existing application to take advantage of the cloud-native features. Azure provides several services such as Azure App Service, Azure Functions, and Azure Container Instances that can help organizations to modernize their applications without a complete rewrite.
Rearchitecting involves redesigning the application architecture to take full advantage of cloud-native capabilities. Azure provides services such as Azure Kubernetes Service, Azure Service Fabric, and Azure Event Grid that can help organizations to create scalable and resilient applications.
Rebuilding involves completely rewriting the application from scratch using cloud-native technologies. This approach can help organizations create modern applications that are optimized for the cloud.
Replacing involves replacing the existing application with a cloud-native SaaS solution. Azure provides several SaaS solutions such as Office 365, Dynamics 365, and Power Platform that can help organizations to replace their existing applications with cloud-native solutions.
After choosing the modernization approach, the next step is to migrate the application to Azure. Azure provides several tools such as Azure Site Recovery, Azure Database Migration Service, and Azure Data Box that can help organizations to migrate their applications to the cloud with minimal downtime.
Once the application is migrated to Azure, the next step is to optimize and manage the application. Azure provides several services such as Azure Monitor, Azure Security Center, and Azure DevOps that can help organizations to monitor, secure, and manage their applications in the cloud.
In conclusion, application modernization using Azure cloud can help organizations to leverage the latest technologies and cloud capabilities to create modern, scalable, and resilient applications. Azure provides several tools and services that can help organizations to assess, choose, migrate, and manage their applications in the cloud.
