Comparing Cloud File Storage Solutions: AWS EFS, Azure File Storage, and Google Cloud Filestore

In the world of cloud computing, file storage services are essential for applications requiring shared file systems, data persistence, and high availability. AWS Elastic File System (EFS), Azure File Storage, and Google Cloud Filestore are three leading file storage solutions offered by major cloud providers. In this blog, we will compare these services to help you make an informed decision about which one best suits your needs.

1. Overview

AWS Elastic File System (EFS): AWS EFS provides scalable, fully managed, and highly available file storage for use with Amazon EC2 instances. EFS is designed to support a broad spectrum of workloads and is particularly suited for applications that require a shared file system.

Azure File Storage: Azure File Storage offers fully managed file shares in the cloud, accessible via the Server Message Block (SMB) and Network File System (NFS) protocols. This service is ideal for replacing or supplementing on-premises file servers and supports seamless integration with Windows and Linux environments.

Google Cloud Filestore: Google Cloud Filestore provides high-performance file storage for applications that require a fully managed NFS file system. Filestore is designed for workloads that need high IOPS and low latency, such as content management, media rendering, and data analytics.

2. Pricing

AWS EFS: EFS pricing is based on the amount of data stored and the throughput provisioned. There are two storage classes: Standard and Infrequent Access (IA), with the IA class being more cost-effective for less frequently accessed data. AWS also offers a free tier with 5 GB of EFS Standard storage.

Azure File Storage: Azure File Storage pricing depends on the type of file share (standard or premium), the amount of data stored, and the operations performed. The Standard tier is suitable for general-purpose file shares, while the Premium tier offers higher performance for IO-intensive workloads. Azure provides a free tier with 5 GB of Standard storage.

Google Cloud Filestore: Filestore pricing is determined by the type of instance (Basic or High Scale), the capacity of the file share, and the performance requirements. Google offers sustained use discounts for long-running workloads, which can help reduce costs.

3. Performance and Scalability


  • Scalability: EFS automatically scales up or down based on the amount of data stored, with no provisioning required.
  • Performance: EFS offers two performance modes: General Purpose (for latency-sensitive use cases) and Max I/O (for throughput-oriented applications). It provides consistent low-latency file operations.
  • Durability and Availability: EFS is designed for high durability and availability, with data stored across multiple Availability Zones.

Azure File Storage:

  • Scalability: Azure File Storage allows easy scaling by adjusting the size of the file share without downtime.
  • Performance: Azure offers different tiers, with Premium File Storage providing higher IOPS and lower latency compared to the Standard tier. It supports both transactional and throughput-intensive workloads.
  • Durability and Availability: Azure File Storage ensures high durability and availability, with geo-redundant storage options for disaster recovery.

Google Cloud Filestore:

  • Scalability: Filestore can scale up to 100 TB per instance, with seamless resizing capabilities.
  • Performance: Filestore offers high performance with low latency, particularly with the High Scale tier designed for demanding applications requiring high IOPS and throughput.
  • Durability and Availability: Filestore provides high durability with built-in redundancy, ensuring data availability and reliability.

4. Integration and Ecosystem


  • Integration: EFS integrates seamlessly with AWS services like EC2, Lambda, and ECS. It supports access from on-premises environments using AWS Direct Connect or VPN.
  • Features: EFS offers features like encryption at rest, backup solutions with AWS Backup, and access control with AWS IAM.

Azure File Storage:

  • Integration: Azure File Storage integrates with Azure services like Virtual Machines, Azure Kubernetes Service (AKS), and Azure Backup. It supports hybrid scenarios with Azure File Sync.
  • Features: Azure provides features like SMB and NFS support, encryption at rest and in transit, and integration with Active Directory for access control.

Google Cloud Filestore:

  • Integration: Filestore integrates with Google Cloud services like Compute Engine, GKE, and AI/ML tools. It supports hybrid deployments using Google Cloud VPN or Interconnect.
  • Features: Google offers features like NFS support, automated backups, and seamless integration with Google’s data analytics and AI services.


Choosing the right cloud file storage solution depends on your specific requirements and existing infrastructure. AWS EFS excels in scalability and seamless integration with AWS services, making it ideal for applications requiring a highly available shared file system. Azure File Storage provides robust performance options and hybrid capabilities, making it suitable for enterprises with diverse workloads and on-premises integration needs. Google Cloud Filestore stands out for its high performance and low latency, making it a great choice for IO-intensive applications.

Evaluate your needs, consider the strengths of each platform, and select the storage solution that aligns best with your operational goals and technical requirements. With the right choice, you can ensure efficient, reliable, and cost-effective file storage for your cloud environment.
