Businesses turning to Application Modernization to meet changing needs

3 min read

Modernizing enterprise apps helps developers transform IT systems by improving the agility of the business. This allows businesses to respond instantly to changing market dynamics. Applications that operate in a cloud-based system have greater mobility as they can be accessed and maintained from anywhere.

Modernization of apps also helps businesses improve their corporate scope and analyze new environments. This will result in the creation of an entirely new world of business opportunities while encouraging new innovation, reducing bottom line costs, maintaining top-of-the-range revenue growth, and increasing profit margins.


The real-time accessibility of modern apps, easy data entry through mobile devices, increased security through the use of geo-fencing in mobile apps, encryption, enhanced accuracy in time entry, and tracking the status of projects has improved customer service and decreased the risks associated with digital business operations.

Legacy apps contain custom widgets that people find difficult to navigate through. Migrating applications to web and mobile-ready environments will broaden product accessibility and bring them to a larger group of end users with better functional equivalence.

Modern apps make use of graphical user interfaces that are intuitive and familiar in nature. Using graphical user interfaces provides simplified integration with other applications including Office tools such as Microsoft Word and Excel. Here, application architecture is tiered and built from reusable components. Changes occur at the component level rather than the whole application having to be changed. Applications are available on multiple devices that support web browsers, such as personal computers (Windows and Web) and mobile devices (smart phones and portable devices).

Legacy applications use a text-based interface which users need to familiarize themselves with. They also navigate through fixed structures, which leads to the creation of standalone applications that are  difficult to integrate. Legacy applications are large and often found with a single code base, where any change is a change to the whole application. These applications are constrained by device type and require specific IT expertise for any changes to be made.

What Drives the Application Modernization Services Market

Cheap Enterprise-grade Technology – Open-source software has changed the digital world by providing a path to host-free, customizable, and reliable solutions for businesses. Open-source operating systems and highly effective user-friendly programming languages are widely used in the market. Low-cost amenities, including applications, software, languages, and cloud services, have lowered the required capital for undertaking a modernization project.

Rapidly Maturing Technology – Cloud technology is rapidly maturing. Earlier, there was a shortage of cloud experts. Today, the scenario has totally changed, and we can see an increase in the number of experts for new technologies such as cloud computing. Companies that provide cloud services, such as Amazon and Azure, have gained the trust of large enterprises. Thus, now is the right time to migrate to a cloud-based service and gain the excellent benefits that many huge enterprises have already gravitated towards.

Increasing User and Market Demand – Users demand fast and highly interactive applications to lead their daily life in a more comfortable manner. They also expect these interactive applications to be updated regularly. Moreover, market demand for such apps is also increasing since competitors are constantly upgrading to newer technologies. The solution is to modernize or revitalize applications so that they can keep up with the changing technology of today.

Evaluate Security Threats and Risks – As with all technology, there are risks and threats associated with modernization. The threat of data loss and breach of security, especially in high-risk systems, needs to be accounted for and assessed before going forward with implementation, and appropriate risk elimination measures should be implemented in those areas. Without necessary measures, data loss could adversely affect the modernization and migration process. Better encryption strategies can be implemented to reduce or eliminate the loss of crucial data.

Why Update Legacy Systems?

The answer is that legacy applications are more complex and require heavy maintenance costs for their upkeep. Systems based on obsolete languages and hardware are difficult to integrate with new technologies. Legacy systems cannot easily meet growing customer needs and expectations.

Modernization Options

Migration of languages (3GL or 4GL), databases (legacy to RDBMS, or one RDBMS to another), platforms (from one OS to another OS), and the use of automated parsers and converters are some cost-effective way to modernize legacy systems.


Re-engineering: Legacy applications can be rebuilt on a new technology or platform with similar or enhanced functionality through the adoption of the Service Oriented Architecture (SOA) technique. This is the most efficient way to transform legacy applications.

Re-hosting: Re-hosting means hosting a legacy application on a different platform with no other major changes made. The replacement is performed for middleware, hardware, operating system, and database. Here, application and data are migrated into an open environment.

Package implementation: All or part replacement can be carried out for legacy applications with off-the-shelf software (COTS) such as ERP, CRM, SCM, billing software, and others.

Latest technology for software modernization has made the legacy transformation process cost-effective and accurate. This has resulted in the preservation of legacy investments and minimization of the cost and business impact of migration to an entirely new software. Based on current technological behavior, changing old characteristics on existing application assets will minimize overhead expenses and save time and effort.  Increasing customer expectations and the need for agility in businesses, reliable & optimal use of Big Data, and the use of cloud-native technologies have resulted in an increase in the popularity of application modernization solutions.
