Virtualization has revolutionized system administration by making it possible for software to manage systems, storage, and networks. Design, implement, and tune effective SLOs. Organizations should seek to standardize a single set of tools that everyone will use. This number will likely increase as the SRE discipline matures.

Among the different components of modern software solutions, the database is one of the most critical. Regardless of whether the computing platform to be evaluated is on-prem, containerized, virtualized, or in the cloud, it is crucial to consider several essential factors. For the experiments in this blog, we did not tune the system.

However if you have a containerized workload that you are measuring with Kepler , or a cloud instance based workload that is running in virtual machines, you measure your carbon footprint based on how many and how big the containers and instances are, and how busy their CPUs are.
