I'm skeptical of that cloud microservices wave building up right 
now. I suspect what's coming is a decentralized mobile wave, just 
as the PC once replaced big iron like mainframes and 
minicomputers, since top mobile CPUs now rival desktop CPUs:

"the [Apple] A12 outperforms a moderately-clocked Skylake CPU in 
single-threaded performance"

Many of the crypto-coins are trying to jumpstart a decentralized 
app ecosystem: someone will succeed.
