This is 100% the case. I would actually argue that it is the only job of the SRE organization - hit the budgets by balancing costs of availability vs. costs of unavailability. If the org has massive budgets and general budget flexibility then it is easy. Otherwise, SREs are magicians to pull the rabbits out of a hat inventing the most awe inspiring methods/tools/hacks/workarounds needed to meet and beat budget targets.
In the other orgs SREs are an indirect level of outsourcing of everything to SaaS providers.
