AWS, Azure, and GCP all offer powerful storage options, but they work differently, cost differently, and fit different needs. This guide breaks down every storage type across all three clouds, in plain English, so you can make the right choice without getting lost in technical noise.
According to recent market data, AWS leads with around 31% global cloud market share, Azure follows at 23 to 25%, and GCP holds 11 to 12%. Together, they control nearly 68% of the global cloud market. Around 75% of enterprises now use more than one cloud provider, picking each one for what it does best. That makes understanding their storage options even more important.

Quick Overview: AWS vs Azure vs GCP Storage Types
Every cloud provider offers four main types of storage. Here is how they map across AWS, Azure, and GCP:
| Storage Type | AWS | Azure | GCP |
| Object Storage | Amazon S3 | Azure Blob Storage | Cloud Storage |
| Block Storage | Amazon EBS | Managed Disks | Persistent Disk |
| File Storage | Amazon EFS / FSx | Azure Files | Filestore |
| Archive Storage | S3 Glacier | Azure Archive Blob | Coldline / Archive |
- Object Storage: AWS S3 vs Azure Blob Storage vs Google Cloud Storage
Object storage is what most people think of when they say ‘cloud storage.’ It is used to store files, images, videos, backups, and application data at massive scale.
AWS S3 (Simple Storage Service)
Amazon S3 launched in 2006 and is still the most widely used object storage service. It is trusted by Netflix, Airbnb, and thousands of other companies worldwide. S3 offers multiple storage tiers for different needs:
- S3 Standard: For frequently accessed data. Costs around $0.023 per GB per month.
- S3 Intelligent-Tiering: Automatically moves data between tiers based on access patterns, saving money without manual work.
- S3 Standard-IA (Infrequent Access): For data you need less often but still need fast when you do.
- S3 Glacier and Glacier Deep Archive: For long-term archiving. Glacier Deep Archive starts at around $0.00099 per GB per month, making it the cheapest archive option on the market.
S3 also comes with advanced features like object versioning, cross-region replication, S3 Object Lambda, and S3 Batch Operations. Learn more about AWS storage options from TeleGlobal’s AWS Storage Services page.
Azure Blob Storage
Azure Blob Storage is Microsoft’s answer to object storage. It is the best pick if your company already uses Microsoft tools like Active Directory, Office 365, or .NET. Azure Blob offers four performance tiers:
- Premium: For performance-sensitive applications with very low latency needs.
- Hot: For frequently accessed data. Priced at approximately $0.018 per GB per month, making it slightly cheaper than AWS S3 Standard.
- Cool: For data accessed less often. More affordable than Hot tier.
- Archive: One of the cheapest archive options in the market, starting at $0.001 per GB per month.
A standout feature of Azure Blob is Data Lake Storage Gen2. It adds a hierarchical namespace, meaning it works like a file system. This makes it ideal for big data workloads using Spark, Hadoop, or Databricks. Azure Blob also provides Zone Redundant Storage (ZRS) for high availability.

Google Cloud Storage
Google Cloud Storage is clean, fast, and tightly integrated with Google’s analytics and AI tools. It offers four storage classes:
- Standard: For frequently accessed data. Around $0.020 per GB per month.
- Nearline: For data accessed once a month or less.
- Coldline: For data accessed less than once a quarter.
- Archive: For data accessed less than once a year.
GCP’s standout feature for object storage is Autoclass. This feature automatically moves objects between storage classes based on real access patterns. You do not have to write complex lifecycle rules. Autoclass does the work for you. GCP Cloud Storage also shines when paired with BigQuery for analytics workloads. For teams doing AI and machine learning, this combination is hard to beat.

| Egress (first 10 TB) | $0.09/GB | $0.087/GB | $0.12/GB |
- Block Storage: AWS EBS vs Azure Managed Disks vs GCP Persistent Disk
Block storage works like a hard drive attached to a virtual machine. It is used for databases, operating systems, and high-performance applications. You need block storage when you need fast, low-latency disk access.
| Feature | AWS EBS | Azure Managed Disks | GCP Persistent Disk |
| SSD Tiers | gp3, io1, io2 | Ultra, Premium, Standard SSD | Extreme, SSD, Balanced |
| HDD Option | st1, sc1 | Standard HDD | Standard HDD |
| Multi-Zone Replication | Manual | Built-in | Regional option |
| Best For | AWS EC2 workloads | Windows/Azure VMs | GCP Compute Engine |
AWS EBS is extremely flexible and pairs directly with EC2 instances. Azure Managed Disks are deeply integrated with the Microsoft ecosystem and support RBAC through Active Directory. GCP Persistent Disk offers both zonal and regional disk types, where regional disks synchronously replicate data between two zones for better protection.
TeleGlobal helps businesses manage all three through its Hyperscaler Services and Cloud Managed Services.
- File Storage: AWS EFS vs Azure Files vs GCP Filestore
File storage is shared storage that multiple servers can access at the same time. Think of it like a shared drive on your network, but in the cloud.
- AWS EFS (Elastic File System): A managed NFS service that scales automatically to petabytes. Supports Standard and Infrequent Access modes. AWS also offers FSx for Windows (SMB shares) and FSx for Lustre (for high-performance computing).
- Azure Files: Four performance tiers with optional snapshots and backup. Perfect for companies using Windows applications or needing SMB file shares in the cloud.
- GCP Filestore: Managed NFS available in HDD, SSD, and High Scale SSD tiers. Suitable for workloads that need POSIX-compliant file access.
- Archive Storage: Long-Term and Low-Cost Cloud Storage
If you store data for compliance, backup, or regulatory reasons and rarely need to retrieve it, archive storage is what you need. All three clouds offer very cheap archive options.
| Feature | AWS Glacier | Azure Archive Blob | GCP Archive |
| Price per GB/month | $0.00099 (Deep Archive) | $0.001 | $0.0012 |
| Retrieval Time | Minutes to hours | Hours | Milliseconds to hours |
| Retrieval Cost | Varies by speed | Higher per GB | Varies by class |
| Best For | Rarely accessed legal/compliance data | Microsoft-ecosystem archiving | Analytics + archiving together |
AWS Glacier Deep Archive at $0.00099 per GB is the cheapest archive option in the market as of 2026. Azure Archive Blob is a close second and is the best choice if you are inside the Microsoft ecosystem. GCP Archive pairs well with BigQuery if you still want to run analytics on archived data.
