Clustering
Simply put, clustering is nothing but adding more than one server to provide the same service. It will help us to avoid interruptions during disasters such as system crashes and other unfortunate situations. Clustering can be used as a failover system, a load balancing system, or a parallel processing unit.
A failover cluster is a group of servers with the sample applications duplicated in all servers to provide the same services to clients to maintain the high availability of applications and services. If a server fails for some reason, the rest of the servers will take over the load and provide uninterrupted services to consumers.
- Scaling up (vertical scaling): This is about adding more resources to our servers, for example, increasing the RAM, hard drive capacity, and processors. Though it might be a good option, it will only be applicable for certain scenarios, not all. In some cases, adding more resources might be expensive.
- Scaling out (horizontal scaling): Unlike adding more...
