Azure Application Modernization Approaches
Outdated legacy applications pose challenges with obsolete IT infrastructure and high maintenance costs. Microsoft Azure Cloud offers a practical solution to upgrade and cut IT/SDLC expenses. This robust cloud platform presents three maturity levels for modernizing legacy applications:
Cloud Infrastructure-Based Applications
In this approach, it actively migrates or rehosts your current on-premises applications to the Infrastructure as a Service (IaaS) platform. The applications retain their original composition but gain the capability to deploy to VMs in the cloud. Often termed as “Lift & Shift,” this approach provides:
- Quick migration with minimal disruptions.
- Decreased overhead in infrastructure management.
- A reliable base for subsequent modernization initiatives.
Cloud-Optimized Applications
In this level, you can gain additional benefits without significantly rearchitecting the code by running your app with modern cloud technologies like containers or through other cloud-managed services. You have the flexibility to roll out containers on either PaaS or IaaS for services like databases, monitoring, cache, and seamless CI/CD (continuous integration/continuous deployment) pipelines. This approach optimizes your applications with:
- Enhanced scalability and agility.
- Integration with managed cloud services.
- Reduced complexity and improved performance.
Cloud-Native Applications
The third maturity level is the ultimate cloud goal, but it is optional for many apps. It is driven by your business needs and targets a modernizing approach for mission-critical applications. At this level, you can use Azure PaaS services to move the apps to PaaS computing platforms. New code is often required to be written, especially while moving to cloud-native applications or microservice-based models. This approach helps to gain significant benefits such as agility, speed, cost efficiency, and enhanced performance, which are hard to achieve in a consistent or on-premise application environment. This approach allows businesses to:
- Harness the full potential of cloud-native capabilities.
- Achieve unparalleled scalability and agility.
- Streamline development and deployment processes.
These three scenarios empower businesses of all sizes to embark on a transformative journey with Microsoft Azure Cloud.
Steps for Azure Application Modernization
The process of application modernization with Azure can be broadly classified into three basic steps as listed below:
- Plan and Assess: Begin by carefully defining your app modernization goals and crafting a strategy that sets the stage for transformative action. This initial step involves exploring and evaluating your current apps and environments, laying a solid foundation for the journey ahead.
- Modernize and Migrate: This phase is where innovation meets execution. Modernize your apps in iterative cycles and adjust project scope or strategy as and when needed for optimal results.
- Sustain Success with Operations: Legacy app modernization is an ongoing journey. With a shift to a cloud-first mindset, you get to leverage the arsenal of cloud platform services and tools at your disposal. This allows you to seamlessly secure, govern, manage, and optimize your apps, ensuring they thrive in the dynamic digital landscape.
