What Is EFS And How Does It Work?
EFS stands for Elastic File System, which is a fully managed file storage service provided by AWS (Amazon Web Services). It is designed to scale automatically, allowing you to grow or shrink your storage capacity based on your needs without requiring any manual intervention. EFS is ideal for applications that require shared access to data across multiple instances, such as web servers, content management systems, and big data analytics.
EFS is built to provide high availability and durability. It uses a distributed architecture to ensure that your data is replicated across multiple Availability Zones (AZs) within a region, thereby minimizing the risk of data loss. With EFS, you pay only for the storage you use, making it a cost-effective solution for applications that need to manage large amounts of data.
How Can I Increase The Size Of My EFS?
Increasing the size of your EFS is simple because it is designed to scale automatically.
