Identification of a component for upgrade

A system comprising:

• a topology map module to:
• receive a first topology map that is to describe a desired software configuration for at least one of multiple components in the system;
• generate a second topology map that is to describe a current software configuration for at least one of the multiple components in the system;
• and
• a processor to:
• determine based on the first topology map and the second topology map whether the desired software configuration differs from the current software configuration;
• and
• identify which at least one of the multiple components to upgrade in the system based on the determination the first topology map and the second topology map differ.

A non-transitory machine-readable storage medium comprising instructions that when executed by a processing resource cause a computing device to:

• receive a first topology map that is to describe a desired software configuration for at least one of multiple components in a system;
• creating a second topology map that is to describe a current software configuration for at least one of the multiple components in the system;
• determining a difference between the desired software configuration and the current software configuration;
• and
• identifying which at least one of the multiple components to upgrade based on the determined difference.
