Here is the thing. You don’t need more than one cloud service provider unless you are considering a multi-cloud strategy. And even if you plan to work with all three cloud vendors, you’ll want to know which one is right for specific services.
To help you decide, we’ll share the strengths, pricing, and other differences between Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) below.
Let’s start from the very beginning.
What Is Cloud Computing (And Why Does It Matter)?
Cloud computing is the delivery of computing services, such as servers, storage, databases, networking, software, and more, over the internet, or “the cloud.”
Instead of owning and maintaining physical data centers and servers, you access these resources on-demand from cloud providers like AWS, Azure, and GCP.
- Cloud computing is like renting a fully equipped office space instead of buying a building. You get the facilities you need without the overhead of ownership.
- It is also like “renting” computing power and paying only for what you use, much like paying for utilities such as water or electricity.
Cloud computing matters because:
- It supports diverse applications, from web hosting to big data analytics and AI.
- Your organization can scale resources, and thus operations, up or down based on demand, pay only for what you use, and access advanced technologies without substantial upfront investments.
- You can deploy applications rapidly instead of building physical data centers first.
- Adapting to market changes doesn’t require overhauling complex IT systems, so it’s quicker and less painful.
Overall, the cloud model enables scalability, flexibility, and cost-efficiency. AWS, Azure, and GCP are the leading cloud service providers. The platforms provide the infrastructure and services that power modern applications, enabling businesses to transform and stay competitive in the digital landscape.
What Is Amazon Web Services (AWS)?
AWS is the world’s largest cloud service provider with 34% of the global market. The company provides more than 240 cloud services, ranging from compute to edge to serverless computing.
Among the most popular AWS services are Amazon EC2 (compute), Amazon S3 (object storage), Amazon EBS (block storage), Amazon Lambda (serverless), and Amazon RDS (relational databases).
Who uses AWS services today?
AWS customers include large enterprises and smaller organizations across multiple industries. A few notable examples include:
- Samsung
- Disney
- Adobe
- DoorDash
- Crypto.com
- US Department of State
- Airtable
- Verizon
- Wix
- UK Ministry of Justice
- GoPro
Customers needing global coverage or coverage in specific locations where Azure and GCP are restricted should consider AWS. If you’re looking for flexibility, high scalability, edge computing, and robust security and compliance standards, the AWS ecosystem fits the bill.
What Is Azure Cloud?
Azure is Microsoft’s cloud services arm and a part of its Microsoft Intelligent Cloud ecosystem. Azure Cloud, like AWS, offers a variety of options for your engineers, including IaaS, PaaS, and SaaS services.
Who uses Microsoft Azure services today?
Like AWS, Azure customers comprise Fortune 500 and smaller organizations across diverse industries and use cases. Some of the most successful Azure customers include:
- BP
- Coca-cola
- Chevron
- Delta
- AmtrakBMW
- DocuSign
- Whole Foods
- Uber
- PwC
- Fujitsu
- University of Sydney
Microsoft Azure is most popular among enterprises for several reasons:
- Existing Microsoft licenses: Since many enterprises already use Microsoft products, such as Microsoft 365, SQL Server, SharePoint, and PowerBI, moving to and integrating Microsoft cloud services is often fairly painless.
- Hybrid cloud: Azure offers seamless integration of on-premises, private cloud, and public cloud services. This enables Azure customers to retain their own data centers while taking advantage of the cloud’s benefits.
- Global data centers: Azure has the second-largest data center network worldwide, right behind AWS, to support global deployments or reach underserved regions.
So, how does GCP compare?
What Is Google Cloud Platform (GCP)?
GCP is best suited to companies with cloud-native applications such as Kubernetes, containers, and AI/ML requirements. Google pioneered Kubernetes (container orchestration platform), Istio (service mesh), and several other popular open-source tools.
In addition, the technology that supports Google’s Search powers the platform’s machine learning, artificial intelligence, and data analytics tools.
Who uses Google Cloud Platform services today?
GCP customers include:
- Mercedes Benz
- Bayer AG
- PayPal
- Unilever
- Swiss Airlines
- Total Energies
- Orange
- Data Lab
- Delivery Hero
- TrustPilot
- UbiSoft
GCP is also popular with startups looking to leverage open-source, but tested platforms to grow faster. In addition, agile scaleups usually use GCP’s rapid innovation to grow their revenue and capture market share.
Introductions aside, in what ways do AWS, Azure, and GCP differ?
AWS Vs. Azure Vs. GCP: How to Choose The Best Cloud Service Provider Today
Choosing the best cloud provider for your applications, budget, location, etc., begins with analyzing your requirements. Identifying what you want will lead to the following considerations.
Size matters
A provider with a global footprint can store and back up your data in more geographic locations, improving disaster recovery and resilience. Having access to more Regions, Availability Zones, and edge locations means more room to grow into. It also enables you to take your services closer to your target customers, reducing latency. Yet, more isn’t always better. So, verify that your preferred Availability Zones support the actual services you require.
Security and compliance
All providers offer adequate cloud security measures. However, the specific data encryption, access controls, and security auditing techniques each uses vary. You’ll want to explore these variances for your specific use cases. And, while at it, ensure the measures comply with relevant industry standards and regulations such as GDPR, HIPAA, and PCI-DSS.
Cloud scalability and flexibility
Not all providers offer auto-scaling, increasing and reducing compute capacity based on workload demand. The ones that do also require you to toggle the feature on and off. So, look for a provider that will help you easily scale resources up or down based on your changing needs. This is crucial for meeting optimal performance goals without overspending.
Reliability
Select a provider with a good track record of crucial SaaS metrics, like uptime and low latency. Consider the SLAs of specific services you plan to use rather than a provider’s overall uptime rating. Additionally, verify that your preferred cloud vendor offers explicit SLAs (99.95% and better) and redundant systems to assure uptime.
Cost and pricing
Pay attention to the provider’s pricing model and any additional fees. AWS, Azure, and GCP offer flexible pay-as-you-go approaches. However, they charge differently, and even similar offers, such as commitment use discounts, vary in discount amounts. So, beyond initial costs, consider pricing models that align with your usage patterns and budget goals.
Anticipate and beat vendor lock-in
Don’t limit yourself to one vendor’s capabilities. You can use some functions from one provider and some from another. Look for providers that support multi-cloud or hybrid cloud configurations. Then you won’t have to rely on a single vendor. While at it, consider the cloud provider’s ability to integrate with your existing systems and tools.
Support
Yes, most providers have strong support, especially when you are paying a premium for it. The key is to explore their different service packages. Consider their responsiveness in your region, whether they offer 24/7, email, or phone support, and what specifics are covered by your service level agreements. Also, remember that a strong community and a rich ecosystem of third-party tools and integrations can drastically improve your cloud capabilities.
Ultimately, you want a reliable, cost-efficient, and secure vendor. Take time to research the provider’s reputation and customer reviews. Ask around and talk to people in the industry to get a sense of the provider’s level of service. Ultimately, request a free trial (and use their Free Tiers) to test their ecosystems.

AWS Vs. Azure Vs. GCP: 9 Key Differences That Make The Difference
All three of them support self-service, instant provisioning, autoscaling, compliance, and identity management. Here are some areas where Azure, AWS, and GCP differ.
1. Availability Zones
CSPs offer varying types and levels of service depending on Regions and AZs. Certain services might be available in that location, but their capabilities may be limited in comparison to other locations. Be sure to confirm these details before purchasing.
Amazon Web Services cloud infrastructure spans 105 Availability Zones across 33 regions (with more launching soon).
AWS Regions and Availability Zones
In addition to 600+ points of presence, the vendor has Edge computing sites on every continent except Antarctica. In addition to seamless scalability and low latency, a large network can also offer multi-regional data backups for disaster management.
In comparison, Azure’s global network covers 160 data centers.
Azure Availability Zones in the US
Just like AWS AZs, each Azure Region offers three separate Availability Zones (AZs), each with independent power, cooling, and networking infrastructure. If one or more zones within a region fail, there will be a backup.
Similarly, GCP has a global reach, not as deep as AWS and Azure, but still more than Alibaba Cloud, for example.
GCP Regions worldwide
The closer the services are to the end user, the lower the latency and the better the performance. The over 40 GCP Regions also offer two or three independent Zones in case one or two zones fail or have issues.
2. Services
AWS offers over 243 fully featured cloud products and services, the most by any cloud provider today. The vendor organizes its services and products across categories, including compute, storage, networking, serverless, databases, analytics, and security/compliance/identity management.
AWS cloud services and products categories
Similarly, Azure Cloud offers a wide range of cloud services, with multiple products under each cloud service category.
Azure cloud services and products
While the Google Cloud Platform seems to offer fewer products, at just over 100, you are likely to find the solution you need. Check this out:
Google Cloud Platform services and products
Again, before choosing a provider, be sure to review their service specifications thoroughly to ensure that they will meet your workload requirements.
3. Compute, storage, and networking
The vendors group their instances or virtual machines into different categories based on their suitability to specific workloads, such as:
- Compute-optimized instances/VMs for compute-intensive workloads, or
- Network-optimized instances/VMs for workloads that require low latency and high throughput.
For workloads that require balanced compute, memory, and networking resources, all three also offer general-purpose instances and bare metals.
As far as instance or virtual machine sizes go, GCP’s M2 series virtual machine, which features 12 TB RAM and 416 virtual processors, is the largest of the three cloud service providers. In comparison, AWS and Azure offer instances with a maximum of 128 virtual CPUs and 3.84 terabytes of RAM as well as 128 virtual CPUs and 3.89 terabytes of memory, respectively.
Now, we get it. Finding the right instance type or virtual machine for a specific use case can be tough. A trial-and-error approach might not be feasible for you, and you may not have the funding and luxury to experiment.
That’s why we recommend using CloudZero Advisor, a free tool that helps you pick just the right machines by instance or VM type, size, service, budget, workload, and other factors.
Something else. You can run Linux or Windows machines on Azure, GCP, and AWS. Azure lets you use your existing Microsoft licenses, whereas GCP and AWS require additional Windows licensing costs.
AWS, Azure, and GCP share a lot of similarities in terms of storage, such as fast SSDs, cheaper hard drives, and multiple archiving options. All three vendors also offer object, file, persistent block, and other types of cloud storage.
Some differences here include:
- Azure offers an actual data backup service; Backup
- AWS offers Snowball, a service that allows users to physically carry and transfer petabytes of data when internet transfers aren’t feasible.
- Transfer Appliance, a GCP service, provides a similar feature.
On to the next.
4. Open-source support
AWS has a long history of working with open-source communities. Examples include Apache Kafka, Linux, MySQL, and OpenTelemetry. It also open-sourced projects like .NET Porting Assistant and Babelfish for PostgreSQL to enable developers to switch from proprietary to open-source software.
The Azure cloud platform is increasingly supporting open-source projects, although many are still handled by third parties such as RedHat, Terraform, and Databricks.
However, Google went bigger. Among Google’s Open Source projects are Kubernetes (container orchestration), Istio (service mesh), TensorFlow (machine learning), and Go (programming language), most of which it donated to the Cloud Native Computing Foundation (CNCF). If you intend to integrate or leverage such platforms or tools, GCP may be the best choice.
5. Containers
All three vendors offer managed Kubernetes services to simplify K8s deployments;
Amazon EKS supports a broader range of earlier Kubernetes versions than AKS and GKE, which mainly support the latest versions.
Also, while AKS and GKE offer more pre-configured solutions out-of-the-box, EKS provides more flexibility to customize the cluster setup. For example, you can create custom AMIs for EKS worker nodes. This provides greater customization and control over your Kubernetes environment.
In addition, AWS’s vast, multi-AZ (Availability Zones) support ensures high availability and fault tolerance even for large-scale deployments.
In addition, AWS also offers the Amazon Elastic Container Service (ECS), an AWS-native, managed service for Docker containers. ECS uses Amazon ECR for storing, encrypting, and managing container images.
You can also provision, run, and self-manage Kubernetes on AWS using Amazon Elastic Compute Cloud (EC2) instances. Self-managing Kubernetes on Azure or GCP isn’t as straightforward.
It costs an extra $0.10 per hour per cluster to run containerized apps with EKS than with ECS.
- Azure Kubernetes Service (AKS)
Expect strong integration with Azure services like Azure Active Directory, Azure Monitor, and Azure DevOps. AKS also offers excellent support for developers with integration into Visual Studio and Visual Studio Code. There are also advanced hybrid cloud capabilities with Azure Arc and Azure Stack.
Better still, AKS automatically upgrades the Kubernetes version of your control plane, reducing upgrade burden. You can then upgrade the node pools manually or automatically to match the control plane version.
- Google Kubernetes Engine (GKE):
GKE is often seen as the most aligned with the upstream Kubernetes project because Google originated Kubernetes. GKE is also deeply integrated with the broader Google Cloud ecosystem, including Cloud Storage, BigQuery, and Cloud Pub/Sub.
Also, expect seamless integration with Google’s AI/ML services like AI Platform and TensorFlow. It also supports advanced networking capabilities, including global load balancing and VPC-native clusters.
Better yet, GKE offers a per-second billing model, making it more cost-effective for workloads with fluctuating resource demands compared to AKS and EKS.
6. Artificial intelligence, machine learning, and data analytics
In terms of big data, predictive analytics, and data lakes for AI and machine learning, the three offer quite similar services, but with subtle differences.
GCP offers the most advanced Deep Learning models and powerful hardware accelerators (Cloud TPUs).
Meanwhile, Amazon Web Services and Microsoft Azure both offer ML studios for developing machine learning models. Azure’s studio does not require a deep knowledge of data engineering, Python coding, or open-source libraries the way Amazon SageMaker does.
7. Support and pricing
AWS, Azure, and GCP all use pay-as-you-go pricing, with varying rates if you use the resources on-demand or on a reserved basis (committed use discounts).
About GCP pricing:
- Get sustained use discounts of up to 30% when you use the same instance repeatedly.

8. Uptime and latency
Azure, AWS, and GCP all claim 99.99% (four nines of uptime). However, their Service Level Agreements (SLAs) often guarantee 99.5% uptime for some services and 99.99% for others.
For exact guidelines, the AWS SLAs page details how compensation for service unavailability works (you earn service credits for lower than promised uptime, for example). The Azure SLAs page also talks about this variation in more detail as does GCP’s SLA documentation.
