Chapter 4: Building an Enterprise Cloud 43 Additionally, the organization did not reach the end of its replacement cycle before running out of capacity. This means the company must make an out‐of‐cycle infrastructure purchase to add capacity. Figure 4-1: Traditional infrastructure procurement economics is not a viable solution. With enterprise cloud and hyperconverged infrastructure, you can begin to adopt a just‐in‐time approach to datacenter resources. This method allows you to also adopt cloudlike pay‐as‐you‐go economics. Figure 4‐2 shows what such a scenario might look like. In Year 1, you buy what you need for that year, making sure to keep your purchased capacity just a little ahead of your workload needs. Under this model, you have no zero ROI zone. You’re effectively using what you’ve purchased. Your upfront economics are far better than they are with traditional infrastructure. In short, you aren’t wasting your capacity. Notice that your organization didn’t run out of capacity in Year 4. Instead, your company simply added more nodes to its hyperconverged infrastructure‐based enterprise cloud environment. You’ve successfully operationalized the changes you’ve made to the datacenter environment. These materials are © 2016 John Wiley & Sons, Inc.
