What makes a quality Cloud hosting provider? Part 1 by Richard May.
Short break out:
"How is the supplier operating the platform? Do you have to compete with other users for resources? How does the platform deal with that contention? Different platforms handle this better than others and as many home broadband providers will notice, services can be slow during school holidays. Fine, but can you afford for your applications to be slow due to similar events occurring which are out of your control? I have heard of instances where providers are contending memory by 4 – 8 times on a server.
