Cloud spend management is especially difficult when employees still behave like they're in an on-premises environment. Typically, requests for more capacity often took months, so people would ask for more than they needed upfront. But with cloud, you can start with a low capacity and quickly add more as needed. Making your employees aware of this benefit will support cloud cost optimization.
If you need to spend, consider tagging spending by department, user, process, and more to identify spending trends. Tagging will give your F&A team a better view of where costs are getting out of control and where they may need to allocate more budget in the future.
Bring your cloud providers into the cost optimization discussion too. Providers usually offer models where you "reserve" what you need – you may pay a premium upfront but less in the long run. Many cloud providers even offer spot pricing – pricing that varies depending on the supply and demand in the market. Spot pricing is usually cheaper than the on-demand price for the same thing – and your F&A team will thank you.
