The largest public cloud, and the bill most FinOps teams meet first.
Quick Definition
AWS (Amazon Web Services) is the largest public cloud platform, offering on-demand compute, storage, databases, networking, and hundreds of managed services. Its consumption-based pricing and breadth make cost visibility and optimization essential, and AWS is a primary focus of most FinOps practices.
Amazon Web Services is the biggest public cloud platform. It rents computing power, storage, databases, networking, and hundreds of managed services on demand, billed by what you use. Most companies' first serious cloud bill is an AWS bill.
AWS's breadth is its strength and its cost challenge. With hundreds of services and several pricing models, including On-Demand, Reserved Instances, Savings Plans, and Spot, it is easy to consume more than anyone intended. That is why AWS is the primary focus of most FinOps practices.
Example. A team launches a test database on a Friday and forgets it. On AWS's per-hour billing, that single forgotten resource quietly adds a few hundred dollars by the next review. Multiply that across dozens of teams and the case for cost tooling makes itself.
Compare the big three in AWS vs Azure vs GCP, and see how Opslyft customers like Innovaccer brought their AWS spend in line with revenue.
Mostly on what you run, how long it runs, where it runs, and how you pay: on-demand rates, commitments, or Spot capacity.
Not inherently. Costs depend on workload fit, discounts, and how well usage is managed. Unmanaged spend grows on every platform.
AWS Cost Explorer, budgets, and the Cost and Usage Report. Many teams start there and add a FinOps platform for allocation and automation.
