Why is allowing NFS in security group rules important in a cloud configuration?
Configuring NFS access in security groups is essential for maintaining security, performance, and compliance in a cloud environment
Can EFS be mounted on windows EC2 instances?
While you can access EFS from Windows EC2 instances, it typically requires third-party NFS clients or alternative AWS services, as EFS is primarily designed for Linux-based systems.
How does EFS handle simultaneous writes from multiple EC2 instances without data corruption?
EFS allows multiple EC2 instances to write at the same time using the NFS protocol, ensuring data consistency and reliability. Although it doesn't have built-in file locking, applications can create their own methods to manage concurrent access and avoid data corruption.
Why is allowing NFS in security group rules important in a cloud configuration?
Because without it, your client like (EC2 instance) can't talk to your EFS at all.Amazon EFS uses the NFSv4 protocol, which runs over TCP port 2049.
When you mount an EFS file system from an EC2 instance, it connects via this port. If you security group doesn't allow inbound traffic on port 2049 from the EC2 instance(or it's security group), the connection gets blocked=no mount.
Is EFS suitable for temporary storage?
EFS is not ideal for temporary storage, as it is designed for persistent use cases, including shared file systems for applications.
