The three major cloud hyperscalers — Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) — together account for over 65% of global cloud infrastructure spending. All three are mature, reliable, and capable platforms. But they have meaningfully different strengths, pricing structures, ecosystem integrations, and support models that make one a better fit than the others for specific business situations.
This is not a benchmark comparison — performance benchmarks for specific workloads are widely available and change with every new instance generation. This is a decision framework for business leaders and CTOs choosing their primary cloud platform.
AWS: The Incumbent with the Broadest Service Catalogue
AWS launched in 2006 and has been the market leader ever since. Its primary advantages are breadth — over 200 services covering virtually every imaginable cloud use case — and maturity. Almost every open-source tool, third-party software, and SaaS integration has AWS support by default.
AWS is the strongest choice when:
- You need the widest possible service catalogue, especially for specialised services (AI/ML with SageMaker, IoT, media processing)
- Your team has existing AWS certifications or experience
- You are building a startup or scale-up and want access to the most mature startup program (AWS Activate) and the largest community of developers with AWS expertise
- You need the most extensive compliance certifications — AWS leads the market in third-party compliance attestations
- Your application requires the most mature Kubernetes (EKS) or serverless (Lambda) ecosystem
AWS's relative weaknesses: Pricing is complex and opaque. Cost optimisation requires dedicated effort — AWS bills are notoriously difficult to forecast without tooling. Support tiers are expensive, with meaningful technical support (Business plan) starting at $100/month minimum or 10% of usage. For Microsoft-centric organisations, Azure is usually a more natural fit.
Microsoft Azure: The Enterprise and Microsoft Ecosystem Choice
Azure launched in 2010 and is the second-largest cloud platform globally. Its core competitive advantage is deep integration with Microsoft's enterprise software ecosystem — Active Directory, Office 365, Dynamics 365, Teams, SQL Server, and Windows Server all integrate most naturally with Azure.
Azure is the strongest choice when:
- Your organisation is Microsoft-centric — Windows servers, Active Directory, SQL Server, Office 365
- You have existing Microsoft Enterprise Agreements — Azure Hybrid Benefit and Windows Server licences through EA dramatically reduce costs
- Your development team uses .NET and Visual Studio — Azure's developer experience for .NET is the best in class
- You need the strongest enterprise identity management (Azure AD / Entra ID)
- Your compliance requirements include specific Azure-only certifications (several government-specific compliance frameworks have Azure-first or Azure-only coverage)
Azure's relative weaknesses: Azure's service quality and reliability have historically been more variable than AWS — some services are excellent while others are clearly behind. The management portal (Azure Portal) is widely considered less intuitive than the AWS Console. For Linux/open-source workloads, AWS or GCP is generally a more comfortable environment.
Google Cloud Platform: Technical Excellence and AI Leadership
GCP has the smallest market share of the three but the strongest technical reputation among engineers, particularly for data, analytics, and AI/ML workloads. Google's internal infrastructure innovations — Kubernetes originated at Google, as did many modern distributed systems patterns — give GCP genuine technical depth.
GCP is the strongest choice when:
- Your workloads are data-intensive — BigQuery for analytics is widely considered best-in-class
- AI and machine learning are central to your application — Google's Vertex AI, TPUs, and pre-trained AI models (Gemini APIs) are market-leading
- You are working in Kubernetes-heavy environments — GKE (Google Kubernetes Engine) is the most mature managed Kubernetes offering
- Your pricing sensitivity is high — GCP pricing is often the most competitive of the three, with sustained use discounts applied automatically without any commitment
- Your application needs best-in-class global networking — Google's private fibre network provides superior latency for globally distributed applications
GCP's relative weaknesses: Smaller service catalogue than AWS or Azure. Fewer compliance certifications in some regions. Less enterprise sales and support infrastructure than the other two (though improving). Some concern about long-term product commitment given Google's history of sunsetting products.
For Indian Companies: Local Region Considerations
All three providers have data centres in India. AWS has regions in Mumbai and Hyderabad. Azure has regions in Pune, Chennai, and Mumbai. GCP has a region in Mumbai and is expanding. For workloads requiring data residency in India (RBI guidelines for financial services, healthcare data), any of the three can satisfy the requirement — verify the specific services you intend to use are available in the Indian region, as not all services are available in all regions.
The Practical Decision for Most Indian Businesses
For most Indian businesses without strong existing ecosystem ties:
- General web/app workloads: AWS or Azure — both are equally capable; choose based on your team's existing expertise
- Microsoft-centric IT environments: Azure — the licence savings and AD integration make it the clear choice
- Data-intensive or AI-heavy applications: GCP — BigQuery and Vertex AI are genuine differentiators
- Startups optimising for cost: GCP's automatic sustained use discounts often produce the lowest bills without manual optimisation
