Level up: How to leverage caching in modern applications

[maggiechu26]

Details

The distance between simple backyard or hobby development and successful commercial software applications can usually be measured in performance. Users are impatient and don't like to wait, time is money, right? Your app works great in your development environment, but after time it becomes slow for users in production. Often this is a symptom of data creep or simply the fact that production resources are too expensive, usually, it is because we are re-querying more data than we need, more often than we should.

Traditional data-driven application developers moving into SaaS cloud or distributed computing will come across this just as much as developers just starting out.

Caching is a pattern that is not often described in "hello world" templates and guides but can be used to complement most logic and business processes in some form to improve the efficiency, availability, and throughput of data.

I'd be more than happy to put my hand up for this one, its a bit of a passion of mine and a concept that is often misunderstood and easily abused when you don't think it through. It would be good to hear experiences or opinions from other mentors, I have some of my own but a few anecdotal examples of times when a simple cache strategy saved the day would help.

Sounds like a great topic. I'm still a noob learming, but want to develop a commercially successful learning platform for schoolkids that will be heavily data driven. Speed is of the essence. The last thing I want to do is stress the kids out even more due to a badly written sluggish app. I'm sure I could benefit from listening to someone knowledgeable about this.

This is probably the most common scenario where a solution may works well enough during development to sign off on but things really fall apart after deployment:
