For example, sales records, operation logs, and login alerts are transactional workloads. ![]() Transactional workloads are sequences of data generated at specific points of business processes. With block storage, developers can migrate the containers seamlessly between servers, locations, and operating environments. Like containers, block storage is equally flexible, scalable, and efficient. Containers are software packages that contain the application and its resource files for deployment in any computing environment. Containersĭevelopers use block storage to store containerized applications on the cloud. Block storage provides a high-efficiency alternative to file storage on SANs. The SAN architecture can work with several types of storage in a unified environment, including block storage. This mitigates downtime in the event that a geographic location can't be accessed. It is Important to note that SAN's employ redundancy using either synchronous or asynchronous replication across long distances. ![]() Fabric layer bridges SAN servers and SAN storage with devices like SAN switches, protocol bridges, routers, cables, and gateway devices.Storage layer consists of physical block storage devices like magnetic tape, disk drives, or optical media.Host layer consists of the servers that manage storage access.The SAN architecture consists of three layers: In contrast, a network attached storage (NAS) is a single device that serves files over Ethernet. SAN's typically use fiber channel interconnects. SAN is a complex network technology that presents block storage to multiple networked systems as if those blocks were locally attached devices. Storage area networksĭevelopers often deploy block storage as a storage area network (SAN). Block storage Is used for a wide variety of applications including relational or transactional databases, time series databases, containers, boot disks, and hypervisor files systems. For example, block storage gives you the flexibility to tier fast-changing data on solid state disk (SSD) for the highest performance, and store warm or cold data on lower cost hard drives (HDD).īlock storage’s unique characteristics make it the preferred option for transactional, mission-critical, and I/O intensive applications. This improves system performance as ongoing updates only affect a small number of data blocks instead of an entire file. For example, they can optimize performance by grouping fast-changing data on specific blocks and storing static files on others. ![]() Granular controlĭevelopers gain a high degree of control over storing data on block storage. This makes block storage very efficient for managing large files that require frequent updates. Then, it rewrites the selected block with the new data. Instead of rewriting the entire file, the system identifies the particular block that needs to be amended. Frequent modificationīlock storage supports frequent data writes without affecting performance. ![]() Developers can add new blocks to existing ones to meet growing capacity needs. The block storage architecture is also highly scalable. Developers can share data across multiple environments to ensure high availability. Individual blocks can be configured for different operating systems, such as Windows or Linux. Flexibility and scalabilityīlock storage devices are not constrained to specific network environments. Organizations use Amazon EBS for performance and cost optimization, scale and agility, and for data protection with EBS Snapshots.īlock storage architecture provides multiple paths to the data whereas file storage only provides one path, this is why block storage is preferred for high performance applications. For example, Viasat uses Amazon Elastic Block Store (Amazon EBS) to capture high throughput (highly transactional) data and optimize storage costs. This is required for latency sensitive applications like databases. Because block storage metadata is limited, block storage delivers ultra-low latency required for high-performance workloads. This reduces data transfer overhead and allows the server to efficiently access and retrieve data in block storage. Block storage uses limited metadata but relies on unique identifiers assigned to each block for read/write operations. Metadata is additional data that describes the primary data contained in the storage system. Organizations use block level storage because of the following advantages.
