Introduction to EFS for Scalable File Storage

Need to share files across multiple cloud servers simultaneously without managing complex physical storage infrastructure? AWS EFS offers a fully managed, serverless, and elastic file system that grows and shrinks automatically as you add and remove files. This written course guides you through setting up, configuring, and optimizing EFS to build resilient and scalable storage architectures. You will learn how to provision file systems, mount them to multiple EC2 instances, and implement cost-effective storage tiering. What you'll learn: Understand core cloud storage concepts and how EFS differs from EBS and S3; Configure EFS file systems, mount targets, and security groups; Mount EFS to multiple EC2 instances using modern, secure mounting tools; Manage performance modes and throughput modes to align with your application needs; Apply lifecycle management policies to transition cold data to lower-cost storage classes; Secure your file systems using IAM policies, security groups, and encryption at rest and in transit. We start with the essential terminology of network file systems and AWS storage types before guiding you through step-by-step configuration workflows, access control setups, and cost-optimization strategies. This course is designed for cloud beginners, system administrators, and developers looking to establish shared storage patterns in the cloud. No prior AWS storage experience is required, though basic familiarity with EC2 and cloud fundamentals is helpful. Start reading today to master scalable, multi-instance file storage in the cloud.
