high availability (HA)

In information technology, high availability refers to a system or component that operates continuously over a desired period of time. Availability can be measured against "100% running" or "never failing". Availability standards widely available for systems or products but difficult to implement are called "Five Nine" (99.999%) availability.

As computer systems or networks are composed of many parts, many high availability plans are required not only for data storage and access, but also for backup and failover We will focus on processing. One method is RAID (Redundant Array of Independent Disks) for storage. The latest approach is storage area network (SAN).

Some usability specialists emphasize that in high availability systems all parts of the system must be carefully designed and thoroughly tested before use. For example, new applications that have not been fully tested can be a common point of failure in a production system.

With the latest mission critical systems, high availability (HA) is expected to return to normal operation within minutes within a minimal amount of data loss. HA relates to Disaster Recovery (DR) ability which requires procedures to handle large multi-component failures such as data center floods and terrorist acts. R3 Corda is designed for production deployment in commercial organizations and has a powerful HA and DR functional roadmap from the outset.

The first focuses on back-end block chain infrastructure. The team is developing a high throughput, high availability (HA), and scalable block chain based operating system that will be able to support more application scenarios. Our main goal is to optimize capacity in all aspects, throughput, availability, scalability, etc., beyond Ethereum. Our goal is to provide the best public chain in the world of block chains. The second team is devoted to the block chain products. They optimized the user experience of our block chain resource manager, wallet, forum and official website. Teams are also focused on incorporating powerful applications into the public chain to meet the needs of various product offerings. This is where the distributed application has its full meaning.
