Application Modernization: How to Modernize Your Legacy Applications

Based on a 2019 study conducted by Imaginovation, 44% of CIOs believe that complex legacy technologies create a barrier to nurturing digital growth. To overcome this barrier, we’re finding that many companies are looking for ways to move away from legacy technologies and advance for the future – a process that we refer to as Application Modernization.

Bring your software into the future

Companies are constantly searching for new ways to promote growth and to get ahead of their competitors. Through innovative technologies and maintaining up-to-date practices, businesses are sure to find their competitive edge by cutting costs while increasing productivity and revenue. By modernizing a company’s legacy technology, some organizations have seen revenue growth of up to 14% with productivity enhanced by 40%. As of 2019, most companies are only 20% of the way into maximizing their cloud technology to its fullest potential.

What Is Application Modernization?

Application modernization is the process of taking the bones, or the structure of existing legacy software, and modernizing the infrastructure so that it is up-to-date and can meet a business’s current needs. Depending how many and how much features need to change, the process can vary from being invasive and involving heavy re-coding to being non-invasive by simply linking an app through a modern cloud service or web-based front–end. There are many different forms of application modernization, including:

What are some of the key technologies used in the process?

There are multiple technological components involved in the process of modernization. Some include:

1. Serverless Computing

A cloud-based model that executes functions off-premises in the cloud but does not eliminate the need for a server, despite its name. This technology outsources software code to the cloud provider, which then runs based on individual requests.

2. Containers and Kubernetes

These allow developers to create consistent and scalable applications across a wide array of environments. Having this type of flexibility results in benefits to organizations that are advancing in the cloud.

3. Refactoring a Monolith into Microservices

Monolithic applications tend to be difficult to update for architectural reasons. Since the components of an application are packaged together, it becomes difficult and costly to add features due to the complexity of the integrations.

Monolithic applications are expensive to scale. Scaling the entire application can present challenges and may result in more complications. As an alternative, we see companies transforming monolithic applications into microservices that prove to be more efficient.

Why should your business consider Application Modernization?

There are several reasons why modernization should be something to consider at your company:

1. Performance

Applications work faster and perform better.

2. Efficiency

Application Modernization allows employees the ability to access sophisticated cloud technology to efficiently serve their clients, while unlocking new business opportunities. We’ve also seen significant improvement in employee productivity.

3. Cost Reduction

Modernization reduces operational costs and the amount of time needed to update applications.

What is the Future of Application Modernization?

Modernizing is the first step to discovering other possibilities for investment, such as moving your data into a data lake, and leveraging artificial intelligence and machine learning tools – the opportunities are endless. It’s time for businesses to start seeking education on leaving legacy applications behind to start working towards advancing into the future.
