Elastic Block Storage

Block storage is a type of data storage system that divides data into fixed-sized blocks (chunks) and stores them independently. Each block has its own unique address, allowing it to be accessed and managed separately.
These blocks are typically stored on storage devices like hard drives, SSDs, or SAN (Storage Area Networks). Unlike file storage, which organizes data into hierarchical files and folders, block storage treats data as raw blocks without any file system structure.
Block storage is commonly used in environments where high performance, low latency, and direct access to data are critical. It is often deployed in conjunction with operating systems or applications that manage the file system on top of the block storage.


High Performance
lock storage provides fast read/write operations because data is accessed directly at the block level, making it ideal for applications requiring low latency.
Flexibility
It can be formatted with any file system, making it versatile for different use cases and operating systems.
Scalability
Block storage can be easily scaled by adding more storage devices or expanding existing ones.
Data Integrity
Since each block is stored independently, it allows for efficient error checking and recovery
Databases like MySQL, PostgreSQL, Oracle, and SQL Server require high-speed data access and low latency to handle complex queries and transactions efficiently. Block storage provides the raw performance needed for these operations.
A financial institution running an online banking application needs to process thousands of transactions per second. The database storing customer account information and transaction history must be highly responsive. Block storage ensures that the database can retrieve and update records quickly, ensuring smooth user experiences and compliance with SLAs.


Virtual machines rely on block storage to emulate physical hard drives. Each VM requires its own dedicated storage space, and block storage provides the flexibility and performance needed for virtualized environments.
A software development company uses cloud-based virtual machines for testing and deploying applications. Block storage allows developers to provision storage dynamically, attach/detach volumes to VMs, and ensure consistent performance across multiple instances. This is particularly useful for CI/CD pipelines where frequent builds and deployments occur.
HPC and big data analytics workloads involve processing massive datasets and performing complex computations. These tasks demand high throughput and low-latency storage solutions to ensure timely results.
A pharmaceutical company conducting drug discovery research uses HPC clusters to simulate molecular interactions. The simulations generate terabytes of data that need to be processed and analyzed in real time. Block storage provides the necessary speed and reliability to handle these intensive computational tasks, enabling faster insights and decision-making.
