Or perhaps the first project was budgeted to only handle limited scale and prove feasibility. In which case it was a success, and now that feasibility is proven, scale can be budgeted for. I mean, if people tried to build for mega scale from day one, every pie in the sky idea I have would start with Spark clusters and load balancers and Kubernetes...which obviously is all expensive, time consuming, and may simply not be worth the cost given the business objective.
