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

We ran performance tests for MongoDB on DigitalOcean vs. AWS vs. Azure and found that DigitalOcean performance was in line with, if not better, on both high throughput and low latency in the deployment. DigitalOcean specialized in SSD-based virtual machines called Droplets that are broken down into four simple categories.

In 2013, Amazon experienced a brief outage that lasted approximately 30 minutes. In massively multiplayer online games (MMOs), where players can trade virtual goods, downtime can even have real-world financial implications for players. The key benefit of employing a Multi-CDN strategy is its increased reliability and redundancy.
