Intermediate DevOps Engineer at Gebeya Inc
Optimizing resource management and traffic distribution with persistent data storage
Amazon EBS (Elastic Block Store) is crucial for storing data persistently, particularly configurations, compute data, and databases. EC2 instances offer flexibility in choosing instance sizes, and we use Elastic Load Balancing for traffic distribution. We integrate with AWS Key Management Services for storing cluster keys. Autoscaling mechanisms are beneficial for handling data processing and storage needs efficiently.

Senior Design Engineer at Clovertex
Provides seamless research data management with effortless setup
From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS. Sometimes we go with Weka or other solutions due to this need, so it should have more IO capacity when there is a demand. More performance is needed specifically in the IO area.
