System and method supporting application solution composition on cloud

A system comprising:

• at least one computer connected with at least one memory that stores computer program code executable by the at least one computer;
• and
• a user interface connected with the at least one computer;
• where execution of the computer program code results in performance of operations that comprise,
• in response to input from a user received via said user interface, accessing a database to select at least one predetermined template comprised of a hardware and software instance of a data processing system that is implementable as an application solution on a cloud platform, where the predetermined template is established by an expert and comprises rules concerning certain topologies, costs related to hardware and software products supported in the certain topologies, and constraints associated with the certain topologies;
• comparing the at least one selected template against a set of constraints;
• establishing an instance of a cloud based solution that is customized for the user based on the at least one selected template when the set of constraints is compatible with requirements of the at least one selected template, where the input from the user is comprised of a budgetary amount allocated by the user to establish the instance of the cloud based solution, and where the set of constraints comprises the budgetary amount and further comprises technical requirements of the user for the instance of the cloud based solution, where the technical requirements comprise any resiliency requirements of the user;
• validating the established cloud based solution against user-uploaded software and workloads to ensure that the cloud based solution satisfies requirements of the user;
• where establishing comprises:
• based on specific requirements of the user selecting at least one of the certain topologies as a working template;
• technically validating the working template against the requirements;
• and
• generating the cloud based solution by varying combinations of hardware and software of the working template, where varying takes into consideration any resiliency requirements of the user and any licensing constraints of the user;
• where technically validating the working template comprises:
• testing the working template against user-uploaded software and workloads;
• and
• where validating the established instance of the cloud based solution further comprises testing horizontal and vertical scaling capabilities and any resiliency requirements while considering pricing and any license constraints.
