For a new NC2 on AWS deployment where workload VMs have low storage and memory

requirements but high CPU frequency (>3.0 GHz) requirements, and the goal is to minimize the

number of CPU cores to reduce application licensing costs, the i3.metal instance type is the most

suitable.

i3.metal:

High CPU Frequency: i3.metal instances offer high-frequency Intel Xeon processors (up to 3.1 GHz)

which meet the high CPU frequency requirement.

Low Storage and Memory: These instances come with a balanced amount of storage and memory,

suitable for workloads with low requirements in these areas.

Minimized CPU Cores: i3.metal instances have fewer CPU cores compared to other high-frequency

instances like i4i.metal, making them ideal for minimizing application licensing costs.

Other Instance Types:

z1d.metal: While also offering high CPU frequency, these instances typically come with a higher core

count and more memory, which may not be optimal for minimizing licensing costs.

i4i.metal: Designed for I/O intensive applications with higher core counts.

m5d.metal: Balanced instance type but with more cores and not as high CPU frequency as required.
