Cloud computing comprises several components like storage, CPU, networking, memory, etc. Cloud computing model infrastructure as a service (IaaS) enables you to store data on the internet in block storage. Understanding block storage and its benefits play a crucial role in designing the cloud storage profile. Keep reading this article to get a fair understanding of block storage and its use cases.
What is cloud block storage?
Cloud block storage is one of the most popular data storage formats in cloud computing. Storage area networks (SANs) use block storage to store the data in cloud-based storage environments over the internet. You can also attach it locally if required. Block storage devices come with a fixed storage capacity. These devices divide the data into multiple blocks and store them as individual entities by assigning a unique identifier to each block. Developers can configure each box individually to work with multiple operating systems.
An external operating system controls all the storage volumes and treats them as independent from each other. A guest operating system mounts the physical block storage device as a physical disk.
What is block storage used for, and what are its benefits?
Block storage is a technology that stores data in cloud environments over the internet. It is the most preferred storage technology that provides fast, efficient, and reliable data transportation.
The block storage has the following benefits:
Block storage is a fast, efficient, and most frequently used storage. The application uses block storage for operations like IOPS, DB servers, etc. It offers low latency and rapid IO data access.
Block storage allows expanding a massive volume of data in minimal time. There is no hassle of adding new data blocks as the organization’s storage need grows.
Block storage allows you to move data from one server to another.
- Filesystem Overhead
When developers store data in block storage, it automatically eliminates the OS file system overhead of performing read and write operations. That means the system stores the data only once.
What is block Storage in E2E, and what are its different use cases?
The following is the list of block storage use cases:
- Database storage – Databases require a technology that offers rapid I/O operations and low latency. Block storage is an ideal choice for the database.
- RAID volumes storage – It combines several disks organized through striping or mirroring. Block storages are ideal for fault-tolerance, enhancing performance, and ensuring high availability (HA).
- Applications – Applications like PHP, Java, .net that require processing on the server-side use block storage. Applications like Oracle, SAP also use block storage.
Block storage stores the data for a critical system that impacts business operations.
Difference between block and file storage
File storage is one of the oldest data storage technologies used for direct attached storage (DAS) or network attached storage (NAS). As the name states, file storage is file-based storage where data is stored as a single piece of information inside a folder. Your machine should know the location of the stored file to access it. You can think of file storage as a closet full of drawers. Every object in that closet is arranged in a hierarchical manner like by folder name. If you access your files on your local machine, you have already experienced the file storage.
Block storage is highly structured storage that organizes each block in a fixed structured format for easy indexing and search. On the other hand, file storage hierarchically arranges the data.
The following table summarizes the various features of file and block storage.
|Capability||File Storage||Block Storage|
|Consistency (Read/Write operations)||Strong||Strong|
|Structure||Hierarchically structured||Highly structured at the block level|
|Access Rights||Direct Attached Storage or Network Attached Storage||Storage Area Network|
E2E block storage
E2E cloud offers block-level storage volumes that you can use with your computing nodes. You can attach block storage directly to your computing nodes to perform read or write operations on this node. If you are using Linux, you can mount block storage as you mount a file system. E2E block storage is powered by a combination of SSDs and NVMe drives that offer a balance between price, performance, and capacity.
E2E cloud offers the following block storage plans-
E2E Block Storage is committed to helping enterprises and businesses with their block storage needs. We offer block-level storage volumes that you can configure with high data availability and replication. Learn more about E2E block storage, including its use cases and features.
