Cloud Architecture Design: Should it be Top-Down or Bottom-Up?

Steve Jin wrote the following on DoubleCloud.org:

In my last blog, I discussed how to optimize workloads across the cloud. This is based on the assumption that you already have an existing infrastructure. What if you don’t have an existing cloud infrastructure but would like to design one from scratch? Here is what you should be thinking about to get the most from your new cloud.

First let’s take a look at other types of infrastructures – say a road. When you design a new road, you have to collect data such as population densities around the area, people’s working schedules, what types of vehicles will run on the road, and so on. With that information, you can decide how many lanes you want, what kind of road surface is required, and so on. You don’t just make up the design specification from scratch, and lay down eight-lane freeways everywhere.

The same process applies in designing cloud infrastructure. Unfortunately this is not what we see often today.

...

Jin then discusses the Top-Down Approach, Bottom-Up Approach, and How to Top-Down.
