System and method for deploying application components on distributed it resources

An application platform controller, comprising one or more processors which, alone or in combination, are configured to provide for execution of the following steps:

• receiving the application components and a Service Level Agreement (SLA) including requirements of each of the application components for an application to be deployed;
• requesting a network slice for the application components from a network controller;
• assigning priority values to the application components defining an order in which the application components are planned to be deployed;
• computing a deployment plan for the application components, wherein the network controller is notified and the network slice is reconfigured based on a determination that no deployment plan which meets the requirements is possible using the requested network slice;
• and
• deploying the application components sequentially, using the priority values, to host sites of the IT resources using information from the network controller including existing registrations of users of the application to an access network of the host sites such that replicas of each respective one of the application components are provided at the host sites which provide a minimum latency with respect to a location of the users,
• wherein the priority values are calculated based on the SLA in the application platform controller by:
• creating a graph having the application components as vertices and quantitative bandwidth requirements as weighted edges;
• and
• assigning the priority values to the application components based on shortest paths according to respective values of the bandwidth requirements such that the application components having a higher bandwidth requirement toward a user equipment of the user are given higher priority.
