Application Modernization Using Microsoft Azure

 

The process of updating legacy applications’ internal architecture, platform infrastructure, and/or functionalities is known as application modernization. Currently, much of the conversation about application modernization is concentrated on monolithic, on-premises applications, which are typically maintained and updated using waterfall development processes, and how those applications can be adapted to release patterns and cloud architecture, specifically microservices and DevOps.

 

The advantages of application modernization can typically be summed up as increasing the speed at which new features are delivered, making it possible for other services to consume the functionality of existing applications through APIs, and moving applications from on-premises to the cloud to improve performance and application-scale as well as long-term data center and IT strategy. Like most things, the secret to application modernization success is the strategy and choosing projects where the advantages of speed, scale, cloud, performance, new feature development, etc., are ones that provide the given application with a clear route to improved user experience and ROI.

 

This article will talk about how application modernization works using Microsoft Azure and what benefits it offers. 

 

Benefits of Application Modernization using Microsoft Azure

The benefits of using Microsoft Azure for application modernization are listed below:

 

  • Time to market and accelerated innovations

 

Organizations could spend more time developing when they don’t have to spend as many resources and time managing apps and infrastructure. In addition, the development process is further streamlined by cloud-based tools and services, resulting in a shorter time to market.

 

  • Agility and compatibility

 

The benefit of modernizing apps is that they won’t just function with the newest technology; they will continue to function as the technology changes. This seamlessness enables speedy updates and modifications to satisfy present and upcoming business requirements. Additionally, it can enable automatic scaling, which enables apps to immediately lower expenses in response to abrupt drops in demand while maintaining good performance in the event of rapid demand spikes.

 

  • Efficiency

 

Modernizing existing apps can sometimes be simpler than developing brand-new ones from scratch, provided it is done carefully. Instead of investing time and resources into something new, firms can build on previous investments in this way. Moreover, as opposed to integrating entirely new apps into present operations, app modernization also aids in the retention of several current processes and business continuity.

 

  • Reliability and security

 

Organizations can employ built-in upgrading and security capabilities with a cloud-first strategy to help protect their workloads. Task automation for crucial aspects like performance monitoring, backups, disaster recovery, and high availability might be among the other built-in features.

 

Pillars of Application Modernization using Microsoft Azure

 

The procedures and strategies for effective app modernization ought to support a set of corporate objectives. The Azure Well-Architected Framework, for instance, contains five architectural pillars focused on organizational objectives that can also be used for app modernization:

 

  • Reliability: The capacity of a system to bounce back from errors and carry on.

 

  • Security: shielding data and applications from dangers.

 

  • Cost management: Increasing value while minimizing costs.

 

  • Operational excellence: The operational procedures that keep a system in production functioning smoothly.

 

  • Performance effectiveness: A system’s capacity to adjust to shifts in load.

 

Steps towards Application Modernization

 

Three steps may be used to generally describe the process of modernizing an organization’s apps.

 

  • Planning: Before taking any action, this initial stage needs organizations to consider their application modernization goals and articulate their approach carefully. In order to get ready for change, now is the time to research and evaluate already-existing programs and environments.

 

  • Implementation: Organizations develop new capabilities and start iteratively upgrading their apps during this phase. Organizations have the option to alter the project strategy or scope using an iterative modernization method.

 

  • Operations: Modernizing an app requires ongoing effort. Organizations can leverage cloud platform tools and services to help secure, control, manage, and optimize their apps after they adopt a cloud-first strategy.

 

Microsoft Azure Strategies for Application Modernization

 

The modernization objectives of a business and the requirement for app code updates set these techniques apart from one another. Therefore, during the planning stage, an application modernization strategy is established, and it is put into practice during the implementation stage.

 

  • Rehost: This modernization technique, often known as “lift-and-shift,” emphasizes speed because it essentially necessitates no code modifications. Businesses transfer apps from their old environment to the new one in precisely the same condition.

 

  • Replatform: This strategy falls in between refactoring and rehosting. Replatforming is the process through which businesses modify app code to work with cloud-based technology.

 

  • Refactor: Both productivity and speed are given top priority during refactoring. With this approach, apps simply require minor code changes in order to connect quickly to and benefit from a cloud-first environment.

 

  • Rearchitect: Rearchitecting may be the best strategy if a company wants cloud scalability. Rearchitecting allows for the modification and extension of an app’s functionality and code to improve cloud scalability.

 

  • Rebuild: Rebuilding is occasionally the best choice when reconstructing a program with cloud technologies. Although it requires more effort, it might be necessary if the functionality or longevity of existing apps is constrained.

 

  • Replace: Even after being rebuilt, an app could still fall short of meeting current or future corporate objectives, necessitating its replacement with a pre-made solution. This strategy can save critical development resources and be quicker than rebuilding. However, replacing apps could provide difficulties, such as delays in business operations and restrictions on upcoming modernization projects.
