HA & Clustering High-availability clusters (HA Clusters) are computer-based to provide improved availability of services delivered by that specific cluster. HA Clusters provide levels of redundancy to protect against system component failure. For example, if a server containing a particular application fails, that server is down for the count until fixed. So is that improved availability of services.
HA Clustering eliminates the problem through a series of steps:
- Detect hardware or software failures immediately.
- Immediately start the failed application on a redundant server.
- Clustering software automatically configures the redundant hardware.
- The result? No administration, no oversight and no downtime.
Clustering is applied in a variety of situations. It is used to protect key databases, for file sharing across a global network, business and administration apps for online enterprise and for tracking client services among other important functions. If you're serious about secure data storage, HA Clusters deliver robust security and seamless operation through the use of redundancy.
HA Clusters monitor the health of your system and can be structured in a variety of physical formats from Active/Passive, N+1, N+M and other configurations to adapt the technology to your company's specific needs. At Zibiz, we're able to design data availability solutions that won't fail, or worse, cause split-brain issues where all private links fail simultaneously while the cluster nodes are still operational and running. In this case, each computer in the cluster may attempt to restart all services, creating duplicate services and data corruption.
In addition to quick recovery, clustered systems offer a high-quality customer experience by ensuring transparent failover to both the user and the application,. With multiple systems available, the application can migrate easily from one system to another in the event of a failure or system upgrade, resulting in zero downtime.
