5 Examples of Legacy Systems
It seems most companies use modern software, but practice shows about 30 percent of software in the world is legacy.
When changes are necessary and common development practices are not possible, API based integration is the key to modernization. It’s the most hands-on approach to connect legacy systems with modern systems and cloud apps. Legacy system integration via API accelerates digital transformation and enables new business perspectives.

BUSINESS FLOW SUFFERS FROM APPLICATION INFLEXIBILITY
YOU HAVE AN EXTENSIVE NETWORK OF DATA SOURCES
THE ORGANIZATION’S DATA IS UNDERUTILIZED
THE SOLUTION REQUIRES COMPLIANCE-SPECIFIC APIS (HIPAA, PCI)
Integration of software components is a low-risk approach to modernize a legacy system. It allows connecting data within an organization and out thereby streamlining business processes. There is a couple of scenarios in which API-based approach or web services can be used for systems to communicate.
Before diving into designing and integrating APIs, we identify the business specifics and tech background. As old systems are fairly complex, connectivity may require interventions into core processes. What challenges we are supposed to avoid? Data stored in different sources, data in various formats, lack of standards and documentation. With that in mind, we use the following approaches to system integration:
We expose the API into a separate layout (cloud-based integration platform, hybrid integration platform, third party API integration) to connect it to the server or database through standard protocols. This way, we don’t violate the solution’s architecture, but expand its functionality and gain real-time data access.
We design custom APIs for solutions with the oldest mainframes that do not support basic protocols. This approach is especially useful to consolidate disparate applications under one roof and comply with business logic. However, this process requires a competent modernization provider.

As we mentioned before, clunky architecture could interfere with APIs integration. Some COBOL solutions can’t connect via third party REST APIs, and this restricts your business. Look here for the signs that your architecture requires immediate enhancements.
We exploit the common API protocols to standardize the data exchange between diverse software systems.
