Your company has a custom C++ application used as a test suite, running tests throughout each day on Linux virtual machines. Currently, the full test suite requires several hours to complete, all while operating on a limited number of on-premises servers designated for testing purposes.

The objective is to make this transition while keeping alterations to the test suite itself to a minimum. In this context, what cloud infrastructure solution would you recommend?
