Hardware needs to be as simple as possible, and various complexities and diversity can be realized through software. For example, a data center should not have servers and network devices of different levels and specifications, but two types of physical devices, computing nodes and network core devices, which are extremely simple and clear:
The core function of the computing node, that is, the server, is to calculate and process various data, and its network function is only reflected in the high-performance network during input and output as much as possible.
Switches, as efficient network core devices, focus on network-related processing, participate in user calculations as little as possible, and remain transparent to user calculations.
When introducing the advantages of the Nitro system on the AWS official website, the first mention is “faster innovation”:
