Cloud Application Modernization and Migration Methodology Rajaraajeswari Settu and Pethuru Raj
Abstract In the midst of all the noise, hype, and hope for the cloud-inspired business augmentation and acceleration, there is a big market opening up for application modernization and migration engagements. That is, worldwide service providers and IT divisions are readying themselves with procedures, key guidelines, metrics, tools, and practices to systematically accomplish application renovation to be deposited and delivered from optimal and operational cloud infrastructures and platforms. In this chapter, we share some of the insights and information on where to initiate and how to accomplish the cloud movement successfully and without much pain. We present and discuss the method to be followed in order to simplify and streamline the process of assessment, fit-for-purpose analysis, renovation, and movement toward competent and connected clouds. We inscribe the key technical as well as business reasons for such a strategic exercise. Keywords Application modernization and migration • Cloud onboarding • Toolset and processes

Introduction
The key driver for cloudification is that expensive IT resources are lying idle. That is, their utilization rate is abysmally low. Thus, the first and foremost for cloud building is to do initial assessment of all the resources for the proposed cloud infrastructure.

Clouds are being positioned as the consolidated, virtualized, automated, and shared IT infrastructure for efficiently hosting, managing, and delivering scores of servicecentric and enterprise-scale IT resources (applications, platforms, and even infrastructural modules) as services to worldwide users via the public Internet, which is being touted and trumpeted as the cheapest communication infrastructure. In other words, as the knowledge-driven service era sets in and stabilizes steadily, the utility and ubiquity of clouds as the path-breaking and promising service deployment and delivery container is set to climb further. Cloud started its innings as a centralized and converged infrastructure, and now with the maturity of a series of enabling techniques and standards, clouds are being empowered significantly in order to solve high-end problems through a seamless federation of multiple clouds. The main turnarounds and transformations accrued out of the pioneering cloud idea is that clouds enable IT agility, affordability, and autonomy, which in turn provides business automation, acceleration, and augmentation. The goals of IT simplicity and sensitivity are being readied and
