As enterprises move towards a complete digital transformation, one common challenge they face is the monolithic architecture of their legacy applications.

With legacy applications based on single code and single-tiered and two-tiered architectures, enterprises tend to face more challenges as they are vulnerable to risks. Here are some challenges:-

• Single Point of failure - One of the biggest challenges enterprise face due to legacy applications or legacy software is that the failure of a single function, module or functionality can result in the failure of the entire system.

• Higher Dependency - In the legacy applications setting, the teams are highly dependent on each other as they work in traditional silos to develop and deploy applications. This can lead to high cohesiveness and lack of collaboration, which increases the cost and time-to-market of applications.

• Lacks Flexibility - With legacy applications, even a small change or update can bring down the entire system. Be it bigger or smaller changes, it takes several days or even months to reflect. It is extremely difficult to scale up legacy systems as they have large codebases and may cause performance problems.

• Security - The legacy applications do not have the necessary security controls because of the traditional architecture, unsupported versions, old tools which expose the enterprises to threats, and other vulnerabilities and security risks.
