Application Modernization

What is Application Modernization?

One of the best ways to stay competitive in today’s tech-driven economy is to create new value from existing applications. Application modernization is a savvy way to modernize legacy systems in a cost-effective, efficient way. But what is application modernization and how can you achieve it? We’ve put together an introduction to the process in order to help you understand how to turn legacy systems into assets you can leverage for success.

First, it is important to understand what application modernization means. According to CIO’s TechTarget, application modernization is the refactoring, repurposing or consolidation of legacy software programming to align it more closely with current business needs. The overall goal of a modernization project is to “create new value from existing applications.” Because maintaining outdated systems can be both time-consuming and expensive, more and more businesses are choosing to make the move to modernization. Doing so is especially important when legacy software is incompatible with newer versions of operating systems or hardware.
Strategies and Benefits

Legacy systems are usually modernized in increments, rather than all at once. This is because many of these applications are vital to enterprise operations, and a full-scale, simultaneous modernization can pose a real operational risk. How businesses go about modernization largely depends on their specific context. Because of this there are several strategies, each with their own benefits. The following is an explanation of those strategies from Estimation of the Business Value of Software Modernizations.

Architecture Driven Modernization (ADM): This is an initiative that focuses on standardizing views of the existing system in order for common modernization activities, such as code analysis, code comprehension, and software transformation, to be enabled.
Warrants, Maintenance, Upgrade (WMU): This model is ideal for choosing maintenance strategies based on customer satisfaction levels and the effects of applications on it.
SABA: This high-level framework allows you to plan the evolution and migration of legacy systems, with organizational and technical issues in mind.
Model Drive Engineering (MDE): This involves investigation as an approach to both reverse and forward engineering for software code.
Renaissance Method: This allows you to evaluate legacy systems repeatedly from a technical, business and organizational perspective.
Measurement framework based on Goal-Question-Methods paradigm
Visaggio’s Decision Model (VDM): This is a decision-making model enables you to determine which software renewal processes are right for your business, based on both technical and economic qualities of each component.
Software Rewriting and Replacement Times (SRRT): This allows you to determine optimal software rewrite and replacement timing, based on metrics data.
Reengineering Planning Process (RPP): This process model is ideal for estimating the benefits and costs of modernization.

Options

The following are some of the modernization possibilities available to you:

Migration: A cost-effective way of modernizing legacy systems in an efficient way
Re-engineering: A way to rebuild applications in a new platform with enhanced functionality, such as Service Oriented Architecture (SOA)
Re-hosting: Moving legacy applications to a different platform with no major changes
Package implementation: Replacing legacy applications with off-the-shelf software

When your business modernizes outdated applications, your network can be more productive and responsive. If you are ready to get the most value out of your legacy system, the team at YIPS Africa has the experience and expertise to drive your business forward.
