On the completion of cloud roadmap development, we can start with cloud architecture and implementation services covering all approved line of business applications. The data gathered and analyzed during assessment phase on the areas like applications architecture as-is analysis, security model, user management and authentication, database architecture and scalability, data migration needs from on premises to cloud, use of auto-scaling, application and system management and monitoring etc. are all taken-care-of.
Any possibility of PaaS or SaaS services is also considered to make best use of cloud scalability and agility. While implementation is in progress there is a serious need of following the change management concept across all key stakeholder. If dev/test and private cloud stage is not adopted as the initial phase of cloud roadmap then change management in case of implementation and migration becomes of paramount importance and more extensive planning need to be carried out.
