Overall Satisfaction with Amazon Elastic Block Store (EBS)

We use EBS to provide persistent storage to our EC2 instances. It enables us to store data which remains persistent even when the instance is stopped or termimated. And allows us to startup the server without any loss of data. EBS is highly scalable. In case an EC2 instance goes down, it allows us to quickly spin up new instances with same configuration.
  • Provides reliable and secure storage for apps and databasea.
  • Highly scalable
  • Extremely strong backup mechanism
  • Provides enhanced encryption and data protection
  • EBS volume can be attached to only one EC2 instance at a time
  • The volumes are limited to the Availability zones of the instance they are attached to
  • The maximum size is 64TB. We have had usecases where we needed larger volume
  • The backup snapshots are stored on S3 and that's an additional cost.
  • Hogh fault tolerance
  • Data security
  • Data backup
  • Reboot multiple instances using same configuration
  • Data access from EC2 instances has become faster
  • Data storage and access has become much more reliable
  • Improved scalability - Dynamically increase size of the block volume whenever needed
Amazon S3 is an object based storage and not a block based storage. It can be mounted on a volume but cannot be used as a boot volume. Moreover, it is not as fast as EBS. S3 is generally used to store objects for long term storage and not as a persistent storage on an EC2 instance.
