We introduce a caching mechanism in the API gateway layer, allowing us to offload processing from singleton leader elected controllers without giving up strict data consistency and guarantees clients observe. With traffic growth, a single leader node handling all request volume started becoming overloaded.

A quick canary test was free of errors and showed lower latency, which is expected given that our standard canary setup routes an equal amount of traffic to both the baseline running on 4xl and the canary on 12xl. What’s worse, average latency degraded by more than 50%, with both CPU and latency patterns becoming more “choppy.”

This enables customers to serve content to their end users with low latency, giving them the best application experience. In 2008, AWS opened a point of presence (PoP) in Hong Kong to enable customers to serve content to their end users with low latency. Since then, AWS has added two more PoPs in Hong Kong, the latest in 2016.

Cross Region Read Replicas also enable you to serve read traffic for your global customer base from regions that are nearest to them. Cross Region Read Replicas also make it even easier for our global customers to scale database deployments to meet the performance demands of high-traffic, globally disperse applications.

While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. Show me the money!

Those events are then retrieved by the Team Service, which stores all allowed requests into an event registry and collapses that request history into the current state of a team upon receipt of a READ request. This approach also minimizes network traffic throughout the architecture, as all external calls are handled by this service.

As a MongoDB user, it’s crucial to ensure that your data is safe and secure in the event of a disaster or system failure. Especially if going into or out of storage types that may throttle bandwidth/network traffic. In today’s data-driven world, losing critical data can be catastrophic for any organization.

I was a little restricted in my thinking the first time around and I’ve come to see FaaS as something not quite stateless, since caching state in a Lambda instance that might stick around for 5 hours is a perfectly reasonable idea. I also rewrote the section on Startup Latency since Cold Starts are one of the big “FUD” areas of Serverless.
