AWS, Azure, Google Cloud Platform, and Oracle are leading cloud providers that offer flexible compute, storage, and networking services with self-service, instant provisioning, and autoscaling capabilities. Each provider differs in key areas such as pricing, features, and target audience, making it essential to understand the requirements of your teams, applications, and workloads before selecting a vendor. The comparison of storage and compute pricing across these providers reveals that Azure offers the most cost-effective alternatives for general-purpose instances, while Google Cloud Platform provides significant discounts for compute-optimized instances. Additionally, AWS and Azure offer burstable performance instances with 90% off On-Demand rates, but with different requirements for handling interruptions. Oracle's Preemptible VMs provide a flat 50% discount, making them an attractive option for certain use cases. Automation tools like CAST AI can help optimize cloud costs by automatically creating and implementing cost-saving tactics without manual work, resulting in average savings of 63% on Kubernetes bills.
