In today's complex world, operations engineers and Site Reliability Engineers (SREs) are not only concerned with the quality of their infrastructure but also with cost reduction. To achieve this, they can use various tools and strategies provided by popular cloud providers such as Amazon Web Services (AWS) and Google Cloud Platform (GCP). A key step in cost analysis is to track costs over time, including month-to-month and daily analyses, to identify trends and optimize resources. Both AWS and GCP offer billing dashboards and analytical tools, such as Cost Explorer for AWS and BigQuery for GCP, which enable users to analyze their data and set up billing alerts. Additionally, reserved instances, spot instances, and preemptible instances can help reduce costs by offering discounts on compute hours, while bare metal providers like LeaseWeb and OVH offer the best value for the buck. By choosing the right cloud provider and optimizing resources, operations engineers and SREs can make informed decisions to reduce costs and improve infrastructure efficiency.
