Integrated cloud adoption strategy and the below-mentioned solution steps will address significant cloud migration challenges:
Cloud readiness assessment
As part of cloud readiness assessment, a complete business case recommendation (Figure 4) needs to be developed. Cloud journey should focus on minimal risk and impact to current business through a well-defined approach based on business criticality, regulatory needs, business velocity and customer experience
R-Lane Migration Approach
Application rationalization is a key requirement for cloud adoption. This involves identifying the decision paths/ R-Lanes for (Re-host, Re-factor, Re-build, and Re-Architect) the migration. R-Lane methodology drives cloud migration strategy right from assessment, design, build, and migration
Cloud Deployment approach
The migration will need to be a phased approach with a clear strategy for deployment options in terms of model, CSP, and public / private decision. This will vary depending upon the business risk appetite of the firm, a mix of homegrown and COTS applications, complexity of the organization, and end-customer considerations.
The initial phase can focus on crown-jewel critical applications to be retained in a refreshed infrastructure, moving somewhat-critical applications to private cloud and moving non-critical applications into public cloud or SaaS. The subsequent phase can focus on moving somewhat-critical applications to public cloud. A detailed assessment of the landscape is required prior to this decision.
