In my previous post, I discussed the resurgence of domain-specific hardware, and I made the GPU example.
In his post my friend Mario Baldi describes another example: the Pensando (DSC) Distributed Services Card. The DSC is based on an ASIC designed according to the P4 standard.
The P4 standard is covered in detail in Chapter 11 of my book Building a Future-Proof Cloud Infrastructure: A Unified Architecture for Network, Security, and Storage Services.
