Modernize Your Valuable Java Applications

There are numerous reasons why your applications should be updated. Modernization allows for quicker responses to changing business requirements. It also contributes to cost savings. Compliance with growing industry regulations, such as the European Union's General Data Protection Regulation (GDPR), may also necessitate modernization.

Companies that have spent decades developing and maintaining programs must be able to secure their investments by shifting them to the cloud. Re-architecting and rewriting apps may be prohibitively expensive and hazardous, especially for brands operating in complicated ecosystems with various stakeholders and locations. Thus, updating these applications may be the way to go.

This post will examine the most critical factors when updating existing Java programs.

Considerations for Updating Your Applications

The technique we pick may need to alter depending on a few aspects, such as any significant commercial needs, cost, and the application's estimated lifetime.

Here are some crucial questions to think about before commencing such a project.

What are the existing environment's pain points?

When developing applications for cloud deployment, it is critical to consider how modernization can benefit the organization. We must begin by comprehending why the applications exist in their current state and what challenges they were intended to answer effectively. Recognize where the difficulties are. We can learn more by speaking with members of our development team and asking business stakeholders about any issues they are experiencing.

What are the application's main features?

Knowing which features to prioritize can help reduce the time to market. Consider whether it is possible to modernize everything at the same time. If not, what vital features do the users require most urgently?

How long will we use this application?

Depending on the period, the approach to modernization will differ. Consider whether it is a short-term solution or something we want to use for a few years. Security and resilience should be long-term priorities.

What is our financial situation?

When upgrading an application, we must consider the expense. We might investigate alternatives such as employing open-source components instead of commercial ones or selecting technologies that do not require additional licensing fees.

How does our program work in conjunction with other systems?

If our application interacts with other applications, we may need to consider their compatibility.

What expertise do we have on staff?

It may be our best option to have in-house developers who can update the applications. Otherwise, we may wish to outsource the modernization to a trusted partner well-versed in the most recent technologies.

Do we have the necessary developer tools to assist our team?

Before we begin our application modernization project, we must ensure having the necessary tools, such as integrated testing modules for CI/CD.

Do we have well-defined systems in place for communication and collaboration? 

Any modernization project requires collaboration and communication. Ascertain that everyone involved understands their position and has the necessary tools to interact effectively.

Are there any compliance requirements we must follow, such as GDPR privacy regulations?

The scope of our modernization project may be altered due to compliance constraints. Unfortunately, when it comes to meeting compliance requirements, not all technologies are easily adaptable. Thus, this is crucial when deciding which apps to update first.

There are numerous approaches to upgrading applications, but the best results are obtained when all stakeholders collaborate. Throughout the modernization process, planning and testing should assist limit risks and guarantee that timetables and budgets are met.

What are the Benefits of Modernizing Your Applications?

Here are some of the most important reasons we should update our applications.

Optimize resource usage

Inefficient Java applications are common. If our program runs on virtual machines, containerizing it can save us a lot of resources. Modernizing applications allows us to use the computational resources at our disposal and respond to fluctuations in resource requirements more quickly. This also helps us save money.

Reduce time to market

With an application that adheres to the most current industry standards, we may release updates more quickly and set up containers and pipelines to enable frequent deployments. These efforts can help businesses gain agility and promptly bring innovative, cutting-edge offerings to market.

Obtain durable, future-proof applications

Microservices are excellent for breaking down company functionality into independent services that can communicate with one another. We may isolate distinct aspects and apply patches without affecting application uptime, if we develop our applications utilizing microservices architecture. In case of a problem, continuous integration (CI) and continuous delivery (CD) allow to roll back to a previous version of the application easily.

Improve application performance

By modernizing our applications, we may select the optimum technology stack for our users while reducing technical debt. This provides us with greater control over performance and availability. We also gain the ability to grow our application to meet changing business conditions swiftly.

Modernize user experience

Modernizing our applications can improve the end-user experience and help us keep up with users' expectations. Many older programs were created before the adoption of contemporary design ideas. As a result, they are frequently unresponsive and difficult to use.

Improve security

As technology evolves, legacy applications are more likely to develop security flaws. Application modernization can protect against these risks. In addition, modernizing our applications ensures that they meet the most current security standards

Modernizing Your Java Applications

The process of upgrading Java applications can be divided into several steps. Depending on our budget, time, and other constraints, we may choose to focus on one or more of these. They are as follows:

Modernizing the runtime

Rather than sticking with a traditional runtime, which can be costly and inefficient, we must consider switching to a runtime designed for the cloud and containers. We can set up CI/CD pipelines in containerized deployments with lightweight runtimes. This can assist us in optimizing resource consumption, lowering costs, and reducing technical debt.

Modernizing operations

Moving to a Kubernetes-based platform, such as Red Hat OpenShift, AWS Fargate, Docker Swarm, and others, can help modernize operations. Effective container orchestration can enhance application performance, scalability, availability, workload balancing, and failure recovery.

Modernizing architecture

We must consider whether microservices architecture is a good fit for our application when modernizing the architecture. Avoiding monolithic applications and restructuring them into discrete cloud-native components might help our application become more scalable and robust. This allows us to apply updates to components independently via CI/CD pipelines. Microservices can also be scaled to reduce costs.

Suppose we don't have in-house developers with the appropriate expertise. In that case, we should look for a Java modernization partner with the relevant experience and domain knowledge to assist with the modernization process. Getting started with the proper partners on our application modernization journey can be a considerable step toward digital transformation.


Java remains one of the most crucial programming languages for businesses of all sizes, yet scaling Java applications may be complex. Modernizing our Java apps may enable our company to concentrate on strategic objectives and innovation.

In addition, we may utilize the computing resources at our disposal more effectively and react more rapidly to changes in resource needs by modernizing our application.
