Amazon EBS vs Apache Flink: What are the differences?
Amazon EBS: Block level storage volumes for use with Amazon EC2 instances. Amazon EBS volumes are network-attached, and persist independently from the life of an instance. Amazon EBS provides highly available, highly reliable, predictable storage volumes that can be attached to a running Amazon EC2 instance and exposed as a device within the instance. Amazon EBS is particularly suited for applications that require a database, file system, or access to raw block level storage; Apache Flink: Fast and reliable large-scale data processing engine. Apache Flink is an open source system for fast and versatile data analytics in clusters. Flink supports batch and streaming analytics, in one system. Analytical programs can be written in concise and elegant APIs in Java and Scala.
Amazon EBS can be classified as a tool in the "Cloud Storage" category, while Apache Flink is grouped under "Big Data Tools".
Some of the features offered by Amazon EBS are:
- Amazon EBS allows you to create storage volumes from 1 GB to 1 TB that can be mounted as devices by Amazon EC2 instances. Multiple volumes can be mounted to the same instance.
- Amazon EBS enables you to provision a specific level of I/O performance if desired, by choosing a Provisioned IOPS volume. This allows you to predictably scale to thousands of IOPS per Amazon EC2 instance.
- Storage volumes behave like raw, unformatted block devices, with user supplied device names and a block device interface. You can create a file system on top of Amazon EBS volumes, or use them in any other way you would use a block device (like a hard drive).
On the other hand, Apache Flink provides the following key features:
- Hybrid batch/streaming runtime that supports batch processing and data streaming programs.
- Custom memory management to guarantee efficient, adaptive, and highly robust switching between in-memory and data processing out-of-core algorithms.
- Flexible and expressive windowing semantics for data stream programs
"Point-in-time snapshots" is the primary reason why developers consider Amazon EBS over the competitors, whereas "Unified batch and stream processing" was stated as the key factor in picking Apache Flink.
Apache Flink is an open source tool with 9.35K GitHub stars and 5K GitHub forks. Here's a link to Apache Flink's open source repository on GitHub.
According to the StackShare community, Amazon EBS has a broader approval, being mentioned in 179 company stacks & 47 developers stacks; compared to Apache Flink, which is listed in 20 company stacks and 22 developer stacks.

Opstax uses EBS storage to store images, snapshots and to write any data we need to keep when an instance is no longer.
대부분의 EC2 의 스토리지는 EBS 를 마운트해서 사용하고 있습니다. 특히 데이터베이스 서버들의 경우 주기적으로 스냅샷을 생성하여 손쉽게 백업 관리를 진행하고 있습니다.
