Cloud platform overview: The Big Four at a glance  

What is a cloud platform? 

A cloud platform delivers on-demand computing resources over the internet - servers, storage, databases, analytics, AI, and more - so businesses can run and scale apps without the cost and hassle of managing physical hardware. It powers everything from e-commerce stores to enterprise-grade machine learning, all while offering flexibility and speed. 

The market leaders 

According to Synergy Research Group, Amazon Web Services, Microsoft Azure, and Google Cloud collectively command over 60% of the global public cloud market. That includes infrastructure-as-a-service (IaaS), platform-as-a-service (PaaS), and hosted private cloud services. Alibaba Cloud, while not as dominant globally, is a major force in Asia and among the top 5 providers worldwide. Together, these four shape the cloud landscape and choosing between them means aligning your tech stack with the right strengths. 

Amazon Web Services (AWS) 

AWS was first to market in 2006 and still holds the crown, with the largest share of the global cloud pie. It's the most mature cloud provider, offering unmatched service breadth: compute (EC2), storage (S3), networking, databases (RDS, DynamoDB), machine learning (SageMaker), DevOps, and more. With data centers across nearly every continent, AWS gives you global scalability and deep customization options, but its complexity can be a double-edged sword. 

Microsoft Azure 

Azure launched in 2010 and surged quickly thanks to Microsoft’s enterprise reach. If your business already uses Microsoft products like Windows Server, SQL, or Office 365, Azure slides in smoothly. It excels in hybrid cloud setups - connecting on-prem systems to the cloud - and includes services like Azure Virtual Machines (VMs), Blob Storage, and AI tools like Azure Cognitive Services for vision, speech, and language understanding. Azure is also a leader in identity management, powered by Azure Active Directory. 

Google Cloud Platform (GCP) 

GCP hit the scene in 2008 and made its name on innovation. It's the cloud home for data engineers, ML researchers, and analytics-heavy teams. GCP offers some of the best tools in the industry: BigQuery for large-scale data queries, TensorFlow for machine learning, and Google Kubernetes Engine (GKE) for container orchestration. While it trails AWS and Azure in market share, GCP is widely recognized for its strengths in AI, machine learning, and data analytics, making it a popular choice for data-driven teams. 

Alibaba Cloud 

Founded in 2009, Alibaba Cloud is the dominant player in China and a leader across the Asia-Pacific region. While its global market share is smaller, it offers a full stack of cloud services: ECS (Elastic Compute Service), ApsaraDB for database management, and MaxCompute for big data analytics. It also aligns with major data compliance requirements in China and the Asia-Pacific region, making it a go-to choice for businesses targeting those markets. It has a strong track record in e-commerce infrastructure and continues to support digital transformation efforts across emerging markets, particularly in Asia and the Middle East.

Let’s break it down across major decision factors, analyzing how each platform performs in the most critical areas for businesses.

Pricing models and cost management 

AWS 

AWS offers multiple pricing models: pay-as-you-go, Reserved Instances (up to 75% savings), and Spot Instances (up to 90% off). It also includes a 12-month free tier and various long-term savings plans (AWS Pricing). However, its pricing structure can be hard to manage at scale. As Gartner states in its Magic Quadrant for Global Cloud Infrastructure-as-a-Service, AWS pricing is granular and often requires third-party tools for accurate forecasting and cost control. 

Azure 

Azure also uses pay-as-you-go pricing, with added benefits for Microsoft users through Azure Hybrid Benefit, which can cut costs by up to 76% when reusing Windows Server or SQL Server licenses (Azure Pricing). Azure supports spot and reserved pricing, but its pricing complexity - due to layered licensing and discounts - is a common challenge. Microsoft also claims that Azure is cost-effective for businesses running Windows-based workloads.  

GCP 

Google Cloud stands out for its straightforward and competitive pricing. It automatically applies Sustained Use Discounts (up to 30%) and offers Committed Use Discounts (up to 57%) without requiring upfront commitment. GCP also provides a generous free tier and $300 in credits for new users (GCP Pricing). GCP’s use of flexible contracts and aggressive discounts to win enterprise users.  

Alibaba Cloud 

If you’re focused on Asia-Pacific markets, Alibaba Cloud is hard to beat on price. It offers multiple models: pay-as-you-go, subscription, and preemptible instances, along with a calculator to help estimate costs. CAST AI highlights it as one of the most affordable options in the region. Globally, though, pricing may vary more depending on service and location. 

Security and compliance 

AWS 

AWS supports a wide range of global compliance standards like GDPR, HIPAA, and SOC 2. It offers powerful tools like Identity and Access Management (IAM) and encryption at every layer. These give teams fine-tuned control over access and data protection - making AWS a reliable choice for businesses with strict security needs. 

Azure 

Azure is known for strong compliance support, especially for enterprise and government needs. Tools like Azure Policy and Microsoft Defender for Cloud make it easier to stay compliant while managing resources at scale, and everything connects smoothly with Microsoft systems. 

GCP 

Google Cloud uses default encryption and a zero-trust security model. It meets most global compliance standards and is known for making security easy to manage. Its architecture is a good fit for teams that need security by default without complex configuration. For startups handling sensitive data, Google’s security-first approach is appealing. 

Alibaba Cloud 

Alibaba Cloud is focused on regional compliance, particularly in Asia-Pacific. The platform details certifications like China’s MLPS 2.0, GDPR, and others relevant to local markets. It’s a solid option if you operate heavily in China or Southeast Asia, but international certifications may not be as broad or familiar to global enterprises. 

Machine learning and AI capabilities 

AWS 

AWS offers a wide range of AI and ML tools for developers and enterprises. Its flagship tool, SageMaker, helps teams build, train, and deploy ML models at scale. AWS also includes prebuilt tools for language, vision, forecasting, and personalization, making it flexible for both experts and teams just getting started.  

Azure 

Azure AI is designed to be accessible and tightly integrated with Microsoft’s ecosystem. It provides ready-to-use APIs for vision, speech, language, and decision-making, while Azure Machine Learning supports building and training custom models. The platform is well-suited for businesses looking to add AI without heavy development overhead. 

GCP 

Google Cloud excels in AI with tools like Vertex AI, TensorFlow, and AutoML. It’s ideal for teams that want to experiment, build, and scale advanced ML models. GCP's deep learning support and flexible infrastructure make it a strong option for AI-first organizations.  

Alibaba Cloud 

Alibaba Cloud focuses its AI services on practical business needs, like e-commerce, search, recommendation engines, and customer service bots. It offers tools such as Machine Learning Platform for AI (PAI) and prebuilt models for visual and language tasks, especially useful for businesses in retail and Asia-based markets. 

Support and service level agreements (SLAs) 

AWS 

AWS doesn’t offer a single, platform-wide SLA. Instead, it provides individual SLAs for each service. For example, EC2 (its VMs service) comes with a regional uptime guarantee of 99.99% and an instance-level SLA of 99.5%. If AWS doesn't meet these guarantees, customers receive service credits based on the length and impact of the outage, with longer outages eligible for larger credits.  

Azure 

Azure also defines SLAs per service. For VMs, Microsoft guarantees 99.99% uptime when at least two instances are spread across different availability zones. If the VMs are in the same zone, the guarantee drops slightly to 99.95%. Single-instance SLAs vary by configuration but always start at a minimum of 95%. Like Amazon, Azure provides service credits when uptime falls below the guaranteed level. 

GCP 

Google Cloud links its SLA to each product. A single VM in the Premium Tier comes with a 99.9% uptime guarantee, which increases to 99.99% if deployed across multiple zones. Like others, Google provides financial credits if uptime falls below the guaranteed thresholds. 

Alibaba Cloud 

Alibaba Cloud sets different SLAs for each of its services, and the exact uptime guarantee often depends on how the service is deployed. For example, its Elastic Compute Service (ECS) guarantees 99.975% monthly uptime for single-instance setups, and up to 99.995% when spread across multiple zones. 

Choosing the right cloud platform for your business needs  

Selecting the right cloud provider isn't just about who offers the most services; it's about finding the perfect fit for your business goals. Whether you're prioritizing cost savings, regulatory compliance, top-notch performance, or expanding your global reach, each platform brings its own unique strengths to the table. 

What to consider before you choose 

Before diving in, take a good look at your workload types, budget, your team's technical skills, and any compliance requirements. Are you running intensive data applications or just simple web services? Do you need lightning-fast access in Asia or Europe? Will your team handle the infrastructure, or do you prefer more hands-off, managed services? Answering these questions will point you toward the best match. 

When AWS makes sense 

If you're looking for a massive array of tools, regions, and integrations, AWS is a solid choice. It boasts the broadest selection of services across computing, storage, databases, AI, and more. With over a decade of experience, it's a dependable option for companies that value flexibility and extensive global infrastructure. 

When Azure is the right fit 

Azure really shines if you're already plugged into Microsoft products like Office 365, Active Directory, or Windows Server. It integrates seamlessly with your on-premise systems and offers robust hybrid cloud capabilities. If your workloads heavily rely on Microsoft's ecosystem, Azure will save you a lot of time and effort. 

When to pick GCP 

GCP is a fantastic option for teams focused on AI, machine learning, or big data. Its tools like Vertex AI and BigQuery are incredibly powerful for analytics and innovation. Plus, GCP tends to be more developer-friendly with simplified pricing and smart defaults. 

Why choose Alibaba Cloud 

If your business is primarily located in Asia-Pacific or you're planning to expand into that market, Alibaba Cloud is definitely worth considering. It offers strong regional coverage, competitive pricing, and services specifically designed for e-commerce and mobile-first applications. 

Conclusion: Build with confidence in the cloud  

Choosing the right cloud platform is a pivotal decision that can significantly impact your business's future. It's not just about selecting a vendor; it's about aligning technology with your strategic goals, ensuring scalability, security, and cost-effectiveness. 

That said, you don’t have to make that decision alone. Working with a trusted cloud partner can help you weigh trade-offs, identify hidden costs, and get you up and running faster with fewer risks. From cloud migration to long-term optimization, expert guidance saves time and money.
