Method and apparatus for optimizing legacy network infrastructure

A system comprising:

• a processor;
• and
• a non-transitory computer-readable medium to store instructions for execution by the processor, the instructions configured to:
• discover a topology of a network in an on-premises datacenter, the topology including hardware and software components in the on-premises datacenter and in one or more hops from an external network to a gateway of the network;
• determine a plurality of parameters of the components that affect performance of applications and services running on the network;
• and
• determine, based on the discovered topology and the parameters, an optimal topology for the network that optimizes one or more of the parameters to improve the performance of applications and services running on the network.

• determine a plurality of parameters of the components that affect performance of applications and services running on the network, the parameters including a number of hops, layers, and loops in the network;
• and
• determine, by running simulations on models generated based on the discovered topology and the parameters using graph theory, an optimal topology for the network that optimizes one or more of the parameters to improve the performance of applications and services running on the network,
• wherein the optimal topology comprises one or more of the following:
• rearranging, replacing, or upgrading a component of the network;
• adding a component to the network;
• reconfiguring one or more of the applications and services running on the network;
• an upgrade path and a schedule for upgrading one or more of the components, applications, and services;
• and a minimum configuration for the network that is sufficient to run the applications and services, the minimum configuration being determined by monitoring load and utilization of the network.
