What is Application Modernization?

Legacy application modernization aligns the existing legacy software stack with modern business and functional requirements using new technologies.

What is the Legacy Application?

It can be any software technology or system that blocks or slows down business processes, making it difficult to adapt to market dynamics.

What are Legacy Systems and Technologies Problems?

Legacy apps are incompatible with today’s new and growing technologies such as cloud computing, mobility, the latest cyber security and API use. Critical disadvantages of legacy systems include high maintenance costs, disparate data that prevent integration between systems and data protection issues.

Why are Modernizing Legacy Applications so crucial?

Well, if a company does not update its software promptly, it loses more in the long term because of the loss of competitive advantage and access to innovative technologies.

Why is now the right moment to update Legacy Software?

  • During Covid-19, many operations have gone digital and businesses need to expand their online presence. Lots of legacy systems are standalone and do not support integration with the latest software. This can affect the flexibility and scalability of the entire organization.
  • The omni-channel business model requires companies to be adaptable and responsive to the needs of emerging markets and the availability of products across multiple channels.
  • Outdated systems exacerbate security risks because some of them do not receive updates or fixes.

What are the Profits of Legacy Application Modernization?

According to a recent report, modernizing legacy applications can save 35% of the infrastructure budget annually and reduce the cost of maintaining and operating applications by 30-50%.

Besides, the result of software modernization will be:

  • Incorporating business intelligence into the core systems.
  • Solving mobility problems.
  • Reducing processing time.
  • Fast analyzing and prevention of fraud.
  • Supporting regulations and compliance requirements.
  • Increasing customer satisfaction.
  • Providing new technology and business channels.
