Translated from 日本語 • View original Earlier this month, AWS announced the launch of a new type of instance, C4 instances, in the EC2 service.
I would like to share a topic.
- Uses Haswell-based CPUs, which Intel customizes and delivers exclusively for AWS. • EBS optimization option as standard. Instead, there is no SSD-based instance storage.
- Only HVM is available virtualization type. PV (paravirtual) is not available.
- Extended networking is also standard equipment, with low latency.
Some users who were expecting a dramatic improvement in performance or something new seem to be disappointed.
My impression is that it has improved the level around HVM only, CPU, storage, and network, and is evolving smoothly as an infrastructure.
