Amazon EFS and Microsoft Azure File Storage compete in cloud-based file storage solutions. Microsoft Azure File Storage appears to have an upper hand due to its extensive features and compatibility with both Windows and Linux environments, which broadens its appeal to more businesses.
Features: Amazon EFS offers automatic scaling, seamless AWS integration, and a shared file system with access control, optimizing for high throughput and low latency. Microsoft Azure File Storage provides cross-platform compatibility, seamless integration with Azure services, and versatile file sharing options, supported by the SMB protocol, which facilitates diverse IT environments.
Room for Improvement: Amazon EFS can enhance data transfer speeds and expand cross-platform compatibility. Broader protocol support in non-AWS environments could increase its usability. Azure File Storage could improve its security compliance and provide better configurations for more complex scenarios. Simplifying the user training process and enhancing detailed documentation could enhance its user-friendliness.
Ease of Deployment and Customer Service: Amazon EFS integrates smoothly with AWS services, emphasizing ease of use and customer-oriented support. Microsoft Azure File Storage excels in versatile deployment, accommodating mixed OS platforms. Both offer quality customer support, but Azure's flexible deployment provides an edge in adaptability across different environments.
Pricing and ROI: Amazon EFS is priced competitively, ensuring a good ROI for AWS-centric applications through its scalability. Microsoft Azure File Storage features flexible pricing catering to diverse organizational needs, enhancing overall value with strategic features. Azure's pricing coupled with its adaptable features could lead to a better long-term ROI compared to EFS, which mainly benefits AWS-specific use cases.

Amazon Elastic File System (Amazon EFS) provides simple, scalable file storage for use with Amazon EC2 instances in the AWS Cloud. Amazon EFS is easy to use and offers a simple interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.
When mounted to Amazon EC2 instances, an Amazon EFS file system provides a standard file system interface and file system access semantics, allowing you to seamlessly integrate Amazon EFS with your existing applications and tools. Multiple Amazon EC2 instances can access an Amazon EFS file system at the same time, allowing Amazon EFS to provide a common data source for workloads and applications running on more than one Amazon EC2 instance.
It’s designed for high availability and durability, and provides performance for a broad spectrum of workloads and applications, including Big Data and analytics, media processing workflows, content management, web serving, and home directories.
