Not putting all your eggs in one basket is a good choice. I think the AWS service catalog makes you adopt more than you need or want anyway, it is a great way of locking people into one vendor.
Putting your single egg into multiple baskets isn't all that much better. Now you have many points of failure rather than a single point of failure.
