Cloud computing has revolutionized the way organizations work, and advancing us to a new technology era. Amazon Web Services, Microsoft Azure, and Google Cloud Platform are the top cloud service providers that dominate the worldwide cloud market.
Nowadays, most enterprises are moving towards the cloud and even multi-cloud environments to harness the benefits offered by cloud computing, such as:
- Decreased CapEx
- Reduced infrastructure maintenance
- Increased availability
- Scalability
Of course, the Big 3 cloud providers possess the experience and expertise to provide a reliable and feature-rich cloud platform. But, before committing to a specific cloud platform, you must do your due diligence and compare each platform to fully understand their capabilities and differences.
In this post, we will see how these platforms stack up against the others.

How to choose a cloud service provider
There are many factors to consider when choosing a CSP. Let’s take a look at the most common angles.
Regions and availability
When choosing a cloud provider, the first thing to consider is its supported regions and availability. These directly impact the performance of your cloud, due to factors like latency and compliance requirements, especially when dealing with data.
As of September 2021, here’s where the Big 3 stand:
- Amazon Web Service has 25 geographic regions with 81 availability zones. 218+ edge locations, and 12 Regional Edge Caches.
- Microsoft Azure runs 60+ regions with a minimum of three availability zones in each region with more than 116 edge locations (Points of Presence).
- Google Cloud Platform has 27 cloud regions with 82 zones and 146 edge locations.
All these platforms provide specialized cloud solutions for the government (Government Cloud). Furthermore, both AWS and Azure offer specialized services that cater to the Chinese market with data centers located in China.
Azure has the broadest geographic coverage compared to the others, while all platforms cover most of the globe. And, showing no signs of slowing, all providers continuously expand their coverage by adding more regions and zones to meet the ever-increasing computing demand.

Common services
AWS and Azure have the largest service catalogs by offering more than 200+ services. GCP currently offers around 100+ services. A general breakdown of services is:
- AWS has the largest catalog of services.
- Azure is a close second with an impressive set of AI, ML, and analytics services.
- Google Cloud Platform comes in third place for the number of services offered.
In this section, let’s take a look at the common service offerings of each cloud platform.
Compute Services
| Service | AWS | Azure | GCP |
|---|---|---|---|
| VM (Compute Instance) | EC2 (Elastic Compute) | Azure Virtual Machine | Google Compute Engine |
| PaaS | AWS Elastic Beanstalk | App Service | Google App Engine |
| Container | AWS Elastic Container/Kubernetes Service | Azure Kubernetes Service (AKS) | Google Kubernetes Engine |
| Serverless Functions | AWS Lambda | Azure Function | Google Cloud Functions |
Database & Storage Services
| Service | AWS | Azure | GCP |
|---|---|---|---|
| RDBMS (Multiple Database Types – SQL, MySQL, etc..) | AWS RDS | Azure SQL/ Database for MySQL/PostgreSQL | Cloud SQL |
| NoSQL | DynamoDB, Simple DB | Azure Cosmos DB, Table Storage | BigTable, Cloud Datastore |
| Object Storage | S3 (Simple Storage Service) | Blob Storage | Google Cloud Storage |

Pricing
The pricing of the cloud platform depends on many factors:
- Customer requirements
- Usage
- The services used
All three platforms offer competitive pricing plans with additional cost management options—reserved instances, budgets, and resource optimization—available to all users.
The consensus in the IT community is that Microsoft Azure has the lowest on-demand pricing while Amazon tends to come somewhere around the middle. However, there is a clear advantage when enterprise customers already using Microsoft services (Windows, active directory, MS SQL, etc.) move to Azure as it is significantly cheaper than other cloud providers.

Summing up the Big 3
Even though AWS is the current market leader in terms of capacity and service, Microsoft and Google are also rapidly growing to compete with AWS.
Microsoft in particular is hot on the heels of AWS with its strong emphasis on the enterprise. Meanwhile, Google continues to evolve its presence by providing excellent integrations with open-source projects and third-party services.
In the end, of course, it all boils down to your specific use case. As the market grows, most enterprises are looking for multi-cloud strategies to leverage the strengths offered by each cloud provider without locking themselves to a single provider.
