Why AWS and Azure Dominate Cloud Infrastructure?

Digital transformation is no longer an option. Companies across all sectors and sizes are realizing that traditional IT infrastructure is not enough to support long-term business growth, innovation and competitiveness.

In this regard, two names emerge repeatedly as the top choice for global enterprises: Amazon Web Services (AWS) and Microsoft Azure. The question is, why them? What sets AWS and Azure apart from dozens of other cloud service providers?

Let's approach these questions with actual facts and data.



1. Consistently Dominating Global Market Share


According to Statista's Q1 2024 report, AWS leads the global cloud market with 31% market share, followed by Microsoft Azure with 25%. Together, they account for more than half of the world's total cloud market.

What does this mean? Global trust in AWS and Azure is not just a trend, but the result of proven performance, technology capabilities and service consistency.


2. Global Reach and Widest Data Center Infrastructure


AWS has 102 Availability Zones in 32 geographic regions around the world and plans to add 15 more. While Azure is available in more than 60 global regions, making it the cloud provider with the most region coverage today.

This means companies can:

  • Store and process data closer to the end user (reduced latency)

  • Meet local data sovereignty regulations

  • Provide high availability services


3. Proven Scalability, Security and Compliance


Both AWS and Azure offer architectures designed for high availability, disaster recovery, and auto-scaling. Both also meet various global security certifications such as:

  • ISO 27001

  • SOC 1, 2, 3

  • GDPR compliance

  • HIPAA (for healthcare)

According to the Gartner Magic Quadrant 2023 report for Cloud Infrastructure and Platform Services, AWS and Azure are in the "Leader" position due to their high commitment to security investments, innovation, as well as a solid partner ecosystem.


4. Flexibility and a Complete Ecosystem of Services


AWS offers more than 200 active cloud services, ranging from compute (EC2), storage (S3), to machine learning (SageMaker). While Azure excels at integrating Microsoft products such as:

  • Azure Active Directory

  • Microsoft 365

  • Power Platform

  • Dynamics 365

Companies can build hybrid, multi-cloud or edge computing solutions with full flexibility without having to drastically change existing business systems.


5. Significant Cost Efficiency and ROI Potential


Many companies are moving to the cloud not only for speed and scalability, but also for cost efficiency reasons.

A report from IDC shows that organizations that migrate to Azure experience an average savings of 30% to 50% on IT operating costs over three years.

While a study by Nucleus Research found that the average ROI from migrating to AWS was 3.2 times the initial investment, in just 12 months.


6. Ready to Embrace Future Technology

Both actively invest in frontier technologies such as:

  • AI & Machine Learning
    Azure AI and AWS SageMaker make it easy to develop predictive models and process automation.

  • Quantum Computing
    Microsoft with Azure Quantum and Amazon with Bracket show commitment to the future of computing.

  • Sustainability
    AWS and Azure are both committed to renewable energy and sustainability. Microsoft even has an ambition to become carbon negative by 2030.


Conclusion: Which One to Choose?


AWS and Azure both offer the power, speed, and reliability to support today's and tomorrow's businesses. Choosing the best platform depends largely on each company's needs, industry and digital strategy.

But clearly, both are not just technology choices, but strategic choices. Cloud infrastructure is no longer just a 'place to store data', but a foundation for building innovation, competitiveness and digital acceleration.
