VMware commercialized the idea of virtual machines, and cloud providers embraced the same concept with services like Amazon EC2, Google Compute, and Azure virtual machines. When an application is triggered, it can cause latency as the application starts. This creates latency when they need to restart.

My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Run performance experiments and measure outcomes — both on mobile and on desktop (for example, with Google Analytics ). Estimated Input Latency tells us if we are hitting that threshold, and ideally, it should be below 50ms. Adjust the argument depending on the group of stakeholders you are speaking to.
