Database architects working with MongoDB encounter specific challenges related to database systems and system growth. Vertical scaling is also often discussed, which involves increasing the resources of a single server, which can have limitations in hardware capabilities and become costly as demands grow.

The layers of platforms start at the bottom with hardware choices such as which CPU architectures and vendors you want to use. The next layer is operating system platforms, what flavor of Linux, what version of Windows etc. Above that there’s a deployment platform such as Kubernetes or AWS Lambda.

While we understand it’s virtually impossible to achieve a linear increase in throughput as the number of vCPUs grow, a near-linear increase is attainable. GS2 is a stateless service that receives traffic through a flavor of round-robin load balancer, so all nodes should receive nearly equal amounts of traffic.

To attempt to apply strict in-order processing would be to impose artificial limitations on our system. That's because to guarantee message ordering is technically very difficult and, even if successful, always comes with tradeoffs like lower message throughput and less scalability that hamper the system's ability to be successful.
