1. A method comprising:
assigning or creating one or more isolation groups for at least one service, wherein resources of services assigned in an isolation group are shared with or without isolation;
wherein an isolation group is defined for at least one resource in each layer and each domain to gather the at least one resource of the at least one service;
linking an isolation profile for each of the one or more isolation groups, wherein the isolation profile comprises at least one policy to protect the at least one resource of the one or more isolation groups, and wherein the isolation profile comprises at least an isolation level to define a type of isolation;
allocating or reallocating the at least one resource to the at least one service based on the isolation profile linked to the one or more isolation groups;
wherein the one or more isolation groups is a root isolation group, or the one or more isolation groups is contained by another isolation group; and
further comprising determining an isolation for the at least one resource of one service by checking an isolation profile of a containing isolation group until all isolation groups in a chain of containing isolation groups, including the root isolation group, are addressed or considered.
