Cloud computing has evolved beyond choosing a single cloud provider. Modern enterprises increasingly adopt a multi-cloud strategy, leveraging services from Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform (GCP), and Oracle Cloud Infrastructure (OCI) to optimize costs, improve resilience, and take advantage of each provider’s unique strengths.
One of the biggest challenges for cloud beginners is understanding that although every cloud provider offers similar services, they often use completely different terminology.
For example:
- AWS calls its virtual servers EC2
- Azure calls them Virtual Machines (VMs)
- Google Cloud calls them Compute Engine
- Oracle Cloud refers to them as Compute Instances
Despite the naming differences, these services solve the same business problem—running applications on virtual infrastructure.
In this guide, we’ll compare the four cloud giants side by side.

Why Learn Multiple Cloud Platforms?
Organizations adopt multi-cloud strategies to:
- Improve reliability and availability
- Avoid vendor lock-in
- Optimize infrastructure costs
- Meet compliance requirements
- Increase disaster recovery capabilities
- Access specialized services from different providers
Understanding multiple cloud platforms makes cloud professionals more valuable in today’s job market.
Compute Services Comparison
Modern enterprises now use multiple providers the virtual machines and processing power required to run applications.
