Modernization with Amazon Web Services

Modernization is inevitable as older legacy applications fail to rise up to modern business challenges. As companies look for ways to modernize their existing infrastructure, it is also important to keep an eye on the costs and the ROI from modernization. Simply moving to the Cloud may not derive the optimal benefits.

CloudLeaf approaches modernization with an incremental approach. We believe in understanding your business need for modernization rather than focusing only on technological enhancement. Our best practices and years of experience in AWS technologies give us the edge to determine the right modernization approach for your organization. We work with your teams to understand the challenges at an operational level. Our ideology is to simplify your business processes, architecture and overall practices using technology. We aim to improve the performance, agility, flexibility and scalability of your existing applications by placing them in the right platform with the perfect infrastructure.

Application Modernization Approaches

Application modernization involves enhancing legacy applications with new functionalities or moving on-premise applications to the Cloud to improve scalability and agility. It also involves retiring old, non-performing applications to reduce TCO. Application modernization is a big part of digital transformation.

Mainframe Modernization with AWS Cloud

Mainframe modernization extends the value of applications, infrastructure and processes that form the core IT system of any organization. These deeply-embedded systems carry the load of business-critical applications. However, mainframes require modernization to enable innovation for the future.

Why Modernize Mainframes:
  • To make business processes more agile and high-performing
  • To broaden mainframe application assets
  • To integrate with new technologies using .Net, Java frameworks, and API, REST/JSON, microservices
  • To support new on-premise or Cloud cost models
