It looks like you're trying to do the right thing here, even though there is no boss or peer who understands exactly what you're doing and can appreciate that fact. Kudos for that :)

To echo tinco's comment, do not try to explain the intricacies of what you're doing to your customers. Put yourself in their shoes and think about what is important to them. Explain just the "end results" of your tooling, emphasizing the points that are important to them and leaving out everything else.

For example, you could say that the caching rework will improve the performance of the system, software-defined infrastructure will ensure minimal downtime in case there's a hardware failure, etc. These are all benefits your customers will understand, even though they may not care or understand how exactly you will achieve them.
