Data processing unit
Adata processing unit(DPU) is a programmablecomputer processorthat tightly integrates a general-purposeCPUwithnetwork interfacehardware.[1]Sometimes they are called "IPUs" (for "infrastructure processing unit" ) or "SmartNICs".[2]They can be used in place of traditionalNICsto relieve the main CPU of complex networking responsibilities and other "infrastructural" duties; although their features vary, they may be used to performencryption/decryption,serve as afirewall,handleTCP/IP,processHTTPrequests, or even function as ahypervisororstorage controller.[1][3]These devices can be attractive tocloud computingproviders whose servers might otherwise spend a significant amount of CPU time on these tasks, cutting into the cycles they can provide to guests.[1]
