Essential Technologies/Tools Involved In Legacy App Modernization
Cloud Computing
An essential part of app modernization is the Cloud migration business tactic to run business functions and operations efficiently in secure Cloud environments. That’s Cloud computing, enabling scalability, agility, and lower cost for your business. It does so through a broad range of alternatives, like private cloud, public cloud, hybrid cloud, and multi-cloud.
Microservices
The Microservices approach helps in the attainment of agility for organizations so that they can handle customer and employee expectations well. With robust component separation and smaller code bases, Microservices ensure high maintainability. As a result, it appears an essential choice for enterprises to use to carry out an effective app modernization.
Containers and Kubernetes
Developers use these technologies to build scalable apps that can adapt to various settings to run smoothly. Containers, to be precise, act as a cloud-specific method that handles application packaging, deployment, and operations. In addition, the role of Kubernetes is to manage containers and automate operational tasks, like app deployment, scaling, and management.
Orchestration and Automation
Orchestration automates operational tasks related to containers. It is mostly used for app modernization, migration, and development. Automation, on the other hand, helps ensure sustainable management of apps and so is a great help in process or workflow management.
DevOps
It defines collaboration between development and operations teams with a focused approach to automation and continuous delivery. In-app modernization, DevOps practices allow integration and deployment and promote Infrastructure as Code (IaC). Adopting such practices helps automate infrastructure management, and ensure automated testing and quality assurance. Moreover, it also allows your development teams to monitor and track app performance and user behavior.
API
An application programming interface (API) is invaluable in app modernization by bridging communication and data shareability between apps. Based on this, you can integrate your aging app with modern, Cloud-hosted systems and leverage the safe Cloud environments without having to replace your existing infrastructure.
What Causes Failure Of App Modernization Projects?
When an app modernization project fails, the counterproductive results of the same collectively harm business. For instance, the serious repercussions of frequent downtime, system failures, wasted resources, and time are bound to happen because of the failed app modernization project. Therefore, the initiative dedicated to modernizing legacy processes is necessary for businesses.
Here are some pointers exploring probable factors that lead to failure in your app modernization projects.
Failure reason #01 – Not determining the right business problems
When the process of modernizing an app is not tied to the core purpose of what business problems it would solve, the likelihood of an app modernization project is bound to fail. Determining problems involves understanding the reason behind the slowdown of your existing business processes, such as accounting or inventory before modernizing their compatibility with new systems.
Failure reason #02 – Being unsure of how the modernized systems would fit the business needs
When a new modernized system is implemented in an organization without considering its probable consequences, the entire workforce ecosystem gets affected drastically as employees have to adapt to the system faster. Instead of shepherding your employees to adapt to the implemented system, the system must adapt and be compatible to meet your current business processes and requirements.
Failure reason #03 – Not understanding if the business needs modernization
Most companies are under the impression that just by modernizing their legacy IT processes to the compatibility of new systems; their business will run better and gain profitable results quickly. That’s a wrong assumption. A complete revamp or modernization of your systems will destabilize your business and your workforce ecosystem. Moreover, it will be counterproductive to how customers interact with your business, putting customer engagement in harm’s way. The best approach toward app modernization is to let it happen in measurable steps.
Failure reason #04 – Adopting inflexible application methodologies
The way agile methodologies have paved the path for smooth and successful app modernization, not adopting this approach is one of the biggest mistakes that leads to failing an app modernization project in your business. Hence, choose an agile application over an inflexible one to make your business future-ready.
Failure reason #05 – Not deploying skilled resources
One of the most important reasons for app modernization efforts falling through is not deploying the right and skilled employees in the project, in the first place. And it mostly happens when most companies try to modernize their business processes by cutting corners. Meanwhile, it is also important to ensure that you have an adequate budget to lead the app modernization process to its successful conclusion, and whether the new solution stands compatible with your business needs.
Apart from the factors mentioned above, a misguided expectation regarding your business value also leads to the failure of your app modernization drive. For example, most companies latch on to value calculations that align with short-term cost cuts and transaction gains over long-term upshots. Ideally, it should focus on transforming the whole digital backbone to keep the business up and running efficiently far into the future.
Secrets To A Successful App Modernization Journey
Assess your business needs
Ensure you are aware of the current state of your business, the goals to achieve, and how to drive transformative results without disruption. Then assess your current systems and workforce so that you can base your understanding of both to lay the groundwork for your business needs and application landscape.
Build a solid plan of action
Use your understanding of your business needs and challenges to build a solid plan of action. This doesn’t just mean achieving a general desire for improvement in your existing business process.
