Cleaning up the cloud resources
Another important part of cloud cost saving is the cleanup operation. When dealing with a large number of workloads or complex projects, lots of resources are created just as a transitional step and are often forgotten about and paid for. In this section, we'll learn how to identify and clean up all the unused and unattached resources in your virtual data center.
Cleaning up unused items, as a first approach, represents one of the short-term, quick-win techniques for cost-saving. But, on the other hand, if they're inserted into a recurring process, this will help you uncover any unassigned or unutilized infrastructure (with operational downfalls) and, in general, uncover the gaps in your operational processes that might need extra effort and have a wider impact than costs. In addition, you should plan to periodically assess the evolution of your infrastructure for any ghost resources that may have been left unassigned and unused.
