Explanation
* Scale-out: Add more servers to do the workload
* Scale-up: Add more resources (such as processors and memory) to existing servers
* Scale-out: Add an additional two-socket system to an existing VMware Cluster
* Scale-up: Add two additional processors to a four-socket system currently equipped with only two processors This is because:
* Scale-out: This is a scaling approach that involves adding more servers or nodes to a system to increase its capacity and performance. It is also known as horizontal scaling. It can help distribute the workload across multiple servers and improve availability and fault tolerance.
* Scale-up: This is a scaling approach that involves adding more resources (such as processors, memory, storage or network) to an existing server or node to increase its capacity and performance. It is also
* known as vertical scaling. It can help improve the performance of a single server and reduce the complexity of managing multiple servers.
