elastic file system Flashcards
serverless, fully elastic file storage so that you can share file data without provisioning or managing storage capacity and performance
Elastic File System (EFS)
pay only for the storage used by your file system and there is no minimum fee or setup cost
True
can EFS be shared between multiple EC2 instances?
Yes
EFS can only mount targets inside its VPC
True
Can EFS be accessed from on-premises?
Yes
is EFS for linux only instances?
Yes
Two performance modes for EFS are
Max I/O , General Purpose
Performance mode which is the recommended mode. Ideal for latency-sensitive use cases, like web-serving environments, content-management systems, home directories, and general file serving
General Purpose
Performance mode can scale to higher levels of aggregate throughput and operations per second. However, these file systems have higher latencies for file system operations
Max I/O performance mode
throughput modes for EFS are
Elastic Throughput, Provisioned Throughput, bursting
Throughput mode where EFS automatically scales throughput performance up or down to meet the needs of your workload activity
Elastic Throughput
Throughput mode where you specify a level of throughput that the file system can drive independent of the file system’s size or burst credit balance
Provisioned Throughput
Bursting Throughput mode,Throughput mode where throughput scales with the amount of storage in your file system and supports bursting to higher levels for up to 12 hours per day.
Bursting Throughput mode
Can you use lifecycle polices in EFS
Yes
