Cloud computing is a booming industry that offers many benefits for enterprises, such as efficiency, scalability, flexibility, mobility, disaster recovery, and security. However, choosing a cloud provider also involves evaluating their privacy and security features, which can vary depending on their architecture, services, tools, and policies.

At the end of the day, business leaders and IT decision-makers have to choose between the three major cloud providers: Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure.

In this article, we compare the main features of cloud services of AWS vs Google Cloud vs Microsoft Azure and discuss why Azure is the clear winner out of the three providers.

AWS vs. Google Cloud vs. Microsoft Azure: Feature Comparison

Feature Comparison

The different cloud providers offer different approaches to data security. It’s important to understand these differences to understand how each provider works to protect your data when it’s at rest and in transit.

The different pillars of cloud security involve physical, infrastructure, and data and access.

Physical Security

In terms of cloud computing, physical security is defined as the security measures in place to keep non-employees of the cloud provider from ever touching the servers.

When comparing Microsoft Azure vs Google Cloud vs AWS, all three cloud providers have highly secure data centers that protect their physical assets from unauthorized access, intrusion, theft, fire, flood, and other threats. At these often massive data center facilities, all three companies deploy multiple layers of security measures, such as:

  • Fences, gates, and doors requiring access cards
  • High-definition video cameras
  • Armed guards
  • Biometric scanners
  • Sophisticated alarm systems

Because of the sensitive nature of data center facilities, many corporate-owned cloud data centers run by Amazon, Google, and Microsoft contain no signage visible from the street.

Cloud data center facilities used for AWS, Azure, and GCP servers also comply with various standards and certifications for physical security related to data protection, such as the International Standardization Organization's ISO 27001, the American Institute of Certified Public Accountants (AICPA)-developed Systems and Organization Controls standards (achieving SOC 1/2/3 certification), and the Payment Card Industry Data Security Standard (PCI DSS).

Infrastructure Security

When comparing AWS vs Google Cloud vs Microsoft Azure, you’ll find that all three have robust infrastructure security. Infrastructure security means all the measures a cloud provider uses to protect their network, compute, and storage resources from cyberattacks, malware, distributed denial-of-service (DDoS) attacks, and data breaches.

Encryption, firewalls, virtual private networks (VPNs), load balancers, identity and access management (IAM), and various monitoring and logging tools are used to secure infrastructure.

Microsoft, Google, and AWS also offer various cyber security services and products that customers can use to enhance their own security posture in the cloud. Some examples are listed in the table below.


Security Services


  • AWS Shield (DDoS protection)
  • AWS WAF (web application firewall)
  • AWS Firewall Manager (centralized firewall management)
  • AWS Inspector (security assessment)
  • AWS GuardDuty (threat detection)

  • Azure Key Vault (key management and secrets storage)
  • Azure Dedicated HSM (hardware security module)

Data and Access Security

The third aspect of cloud security is data and access security, which is primarily the responsibility of each provider’s customers. Basic cloud security involves encrypting data at rest and in transit, controlling user privileges and roles, enforcing policies and compliance requirements, and auditing and reporting activities and incidents. All three cloud providers offer tools and features to help customers secure their data and access the cloud.

Examples of the data access and security approaches for AWS vs Microsoft Azure vs Google Cloud are listed in the table below:


Data and Access Security Features


  • AWS IAM (identity and access management)
  • AWS SSO (single sign-on)
  • AWS Cognito (user authentication and authorization)
  • AWS Organizations (account management and governance)
  • AWS Config (configuration auditing and compliance)
  • AWS CloudTrail (activity logging and monitoring)


  • Google Cloud IAM (identity and access management)
  • Google Cloud Identity (user authentication and authorization)
  • Google Cloud Resource Manager (project management and governance)
  • Google Cloud Audit Logs (activity logging and monitoring)

Microsoft Azure

  • Azure Entra ID (identity and access management)
  • Azure Entra ID B2C/B2B (user authentication and authorization)
  • Azure Policy/Azure Blueprints/Azure Management Groups (policy management and governance)
  • Azure Monitor/Azure Log Analytics/Azure Activity Log (activity logging and monitoring)

As we can see from the above comparison, AWS, GCP, and Azure offer similar basic capabilities around privacy and security in the cloud. However, they differ in some aspects of their implementation details, features, services, and policies.

Customers should evaluate their security needs and preferences before choosing a cloud provider.

They should also follow the best practices for cloud security, such as encrypting data, limiting access rights, applying patches, scanning for vulnerabilities, monitoring for threats, and complying with regulations.

Cloud Storage Features: Microsoft Azure vs AWS vs Google

Cloud Storage Features

Cloud storage is one of the core services offered by cloud providers, allowing customers to store, access, and manage their data in the cloud. Cloud storage can provide many benefits for data management, such as scalability, durability, availability, security, and cost-effectiveness.

However, not all cloud storage services are created equal. By comparing the cloud storage features of AWS vs Google Cloud vs Microsoft Azure, an IT decision-maker can determine which of the three major cloud providers offers the best solution for their desired business outcomes.

Types of Cloud Storage

Cloud storage can be classified into four main types: block storage, file storage, object storage, and archive storage. Each type has its business IT use cases, advantages, and disadvantages.

The following table summarizes the types of cloud storage and their definitions:

Cloud Storage Type


Block storage

Stores data in fixed-sized blocks attached to virtual machines (VMs) as disks. Provides low-latency and high-performance access to data. Suitable for applications that require frequent read/write operations, such as databases and transactional systems.

File storage

Stores data in hierarchical folders and files that multiple VMs or users can access over a network protocol. Provides shared access and simple management of data. Suitable for applications that require file-level access, such as web servers and content management systems.

Object storage

Stores data as objects that consist of data, metadata, and a unique identifier. Provides scalable, durable, and cost-effective access to data over HTTP(S). Suitable for applications that require storing and retrieving large amounts of unstructured data, such as images, videos, online backups, and archives.

Archive storage

Stores data that is rarely accessed or modified for long-term retention. Provides low-cost and secure access to data with high durability and compliance. Suitable for applications that require storing data for legal or regulatory purposes, such as audit logs, historical records, and media archives.

Cloud Storage Services

Each cloud provider offers a wide array of services for each type of cloud storage.

The following table compares the cloud storage services offered by AWS vs Google Cloud vs Microsoft Azure:

Type of Storage

It should be noted that comparing cloud storage options often comes down to choosing Amazon S3 vs Microsoft Azure Blob. The term "Amazon S3" is practically synonymous online with "cloud storage" due to the popularity of the AWS cloud.

Global Availability of Cloud Storage by Region

One of the factors that customers need to consider when choosing a cloud storage provider is the availability of their data across different regions. A region is a geographical area where a cloud provider operates its data centers. Each region may consist of multiple zones, which are isolated locations within a region. By storing data in multiple regions and zones, customers can achieve higher availability, durability, performance, and compliance for their data.

  • AWS operates in 25 regions and 81 availability zones around the world.
  • GCP operates in 27 regions and 92 availability zones around the world.
  • Microsoft operates 69 regions with over 200 global edge locations.

Differing Approaches to Delivering Cloud Services

Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure are the three most popular cloud platforms. Each platform has its own strengths and weaknesses. AWS is the oldest and most established cloud platform, with a wide range of services and a large customer base. Azure is a well-established platform with a strong enterprise focus and excellent hybrid cloud solutions. GCP is the newest of the three platforms and has fewer services compared to Microsoft Azure versus AWS but is growing rapidly.

A CIO often chooses one platform over another based on their specific needs. For example, if they need many services and have an established relationship with AWS, they may choose AWS. If they need strong hybrid cloud solutions and have an established relationship with Microsoft, they may choose Azure. If they are looking for cutting-edge technology and are willing to take some risks, they may choose GCP.

At a high level, there are three key differences to note when comparing Microsoft Azure vs AWS vs Google:

  1. Amazon AWS has the largest catalog of services, and Microsoft Azure is a close second with an impressive set of AI, ML, and analytics services. Google Cloud Platform offers very few services when compared with others.
  2. AWS, Azure, and GCP differ from each other regarding their native AI-assisted coding tools, platform as a service (PaaS) options, and cloud data leak prevention solutions.
  3. All three cloud services offer hybrid cloud solutions, but the AWS and Azure solutions are focused on delivering migration tools needed to ease enterprise IT into the cloud. In contrast, GCP concentrates on creating "cloud native" architectures for SMBs but with relatively fewer tools for mid-to-large enterprise IT organizations.

Microsoft Azure vs. AWS vs. Google Cloud: Pricing

Microsoft Azure vs. AWS vs. Google Cloud: Pricing

The pricing of AWS, GCP, and Azure depends on the type and region of the cloud instances and the billing models they offer.

  • AWS and Azure have similar pricing for compute-optimized instances, while GCP is the highest priced.
  • GCP and AWS have similar pricing for memory-optimized instances, while GCP provides superior memory.
  • For accelerated computing instances, GCP is the highest priced, as it provides more vCPUs than AWS and Azure.

Pricing Models Comparison

AWS provides three pricing models:

  1. On-demand
  2. Reserve
  3. Spot.

With Microsoft Azure, consumers can choose between monthly and prepaid subscriptions. Although we previously mentioned GCP has higher pricing for compute and memory, Google is making an effort to be the most affordable cloud platform option out of the three. That’s why Google often will offer sustained usage discounts to provide customers with the lowest-cost deals.

Microsoft Azure has a more robust lineup of compute products to choose from, while Google markets its platform as having a simpler lineup of compute products. AWS, GCP, and Azure all have pricing calculators to help customers estimate their costs.

Here are some pros and cons regarding pricing for each platform:

  • Amazon Web Services offers a wide range of services with flexible pricing options. However, customers report that AWS has too many options and therefore can be complex to navigate.
  • Microsoft Azure has a strong enterprise focus with excellent hybrid cloud solutions. However, compared to AWS and GCP, customers report that Azure can be more expensive than other platforms.
  • Google Cloud Platform prides itself on delivering truly cutting-edge cloud technology with affordable pricing options. However, IT professionals report that GCP has fewer options for cloud-to-cloud migration and other hybrid cloud services than the other two cloud platforms.
