In the era of data and connectivity, the use of systems, tools and solutions to fulfill various functions and automate various processes is a trend for any type of company. And therefore, the integration between these software, mainly the integration of legacy systems, is one of the challenges in the IT area .

The difficulty in synchronizing information between various software is the fact that each one has a different development and purpose, which can generate connection or security failures.

So how do you know if your system has integration ? What are the main ways to do this in practice? That's what we're going to know from now on.

What do legacy systems represent?

Legacy systems represent a large part of the Brazilian software market. These systems were developed years ago with old languages ​​and monolithic architectures in order to be implemented to solve the challenge of companies to carry out management in an organized way.

These systems, due to their old technology, run into old and complex codes, making it difficult to integrate with new services, especially in the cloud with a web-based connection.

But in practice, the legacy systems used need to remain in use by companies because replacing the legacy system with a new system is an extensive and expensive process. In this case, the most viable option for the operation's growth, and necessary in order not to lose any type of data, is to integrate legacy systems.

And why not keep them separately or replace them?

Maintaining existing legacy systems is not only costly, it also jeopardizes the smooth running of the business as it impedes growth and expansion. Being unable to provide users with access to the latest technologies makes information management difficult.

But replacing a legacy system is also expensive, risky and requires a lot of developers working together, not to mention that it doesn't bring any kind of benefit thinking about the future needs of a company .

Regardless of the size of the companies, they need to look for an ideal solution for the integration of legacy systems.

2 main ways to integrate legacy systems

Focusing on this need to maintain all integration, even with legacy systems in companies, we can list two different ways of doing this process .

1. Using API integration

An API is a program developed focused on performing systems integration. It is from this that a system can perform integration with another, sharing and sending data or information automatically.

But in practice, this way of doing integration ends up not always working. It's just that many software, especially when we talk about the integration of legacy systems, do not initially have an open API to carry out this process.

However, despite API integration having this function, we need to break the myth that only new software that has a developed API can integrate . In practice it doesn't work that way!

It is now possible to make connections between different types of systems, even if they originally did not provide an API. That's what we're going to see in the next way of doing integration.

2. Using an iPaaS

iPaaS (Integration Platform as a Service), systems integration platform as a service, is a cloud solution that works as an automated platform to connect applications and software deployed in different environments.

In practice, iPaaS is often used by B2B (business to business) companies that need to integrate on-premises systems and data with systems and data in the cloud.

This means that this is the solution to, without using some kind of API, connect and integrate legacy systems. That is, the statement of only performing integration if the solution has an API is no longer true .

What are the benefits of iPaaS for integrating legacy systems?

An iPaaS can streamline an organization's overall information flow. By creating a virtual platform, it connects applications and resources to create a framework with multiple shared functionality across the cloud and across select software.

All platform management can occur in a single location, minimizing the work of using multiple systems. In short, iPaaS helps navigate an enterprise's growing integration requirements without adding cost to an IT environment.
