But even AWS admits that only 5% of Enterprise workloads are using any cloud provider.
Also that includes IAAS and PAAS and private cloud services not companies like Linode that offer just a VPS nor places like Rackspace.
If you want a simple group of VPS’s to setup your own website to sell goods and you’re hosting on AWS (outside of Lightsail), you’re doing it wrong.
I’m a cloud true believer, know the ins and outs of AWS well, etc and I wouldn’t use AWS - besides Lightsail maybe - if I just wanted a VPS.
