Engineer at Apple says that 30% of their AWS cloud workloads are already over Amazon's Graviton CPU as opposed to $Intel (INTC.US)$ or $Advanced Micro Devices (AMD.US)$ . He thinks start-ups will go 100% over Graviton as AWS is heavily promoting its own CPU, telling customers that Graviton is 35-40% more cost effective than Intel CPUs.
Going forward, he sees workloads over Graviton increasing. Historically they haven't done so as they like to be able to shift workloads over different clouds e.g. if AWS goes down, start up the workload in GCP.
But with Docker/ Kubernetes-based containers, this additional software layer can abstract away from the local hardware you're using. So if you're running apps in multi-architecture containers, you can easily shift apps between clouds while still making use of the local cloud optimized ASICs such as Graviton.
So basically with multi-architecture containers, you get the best of both worlds i.e. the software flexibility to switch clouds and the benefits of cheap localized ASICs.
