In my previous article, I described a very simple use of feature toggle and how to create it. The challenge is when your application is cloud based and we want dynamically to control features which meets business requirement.
Cloud based feature toggle requires careful planning if your system spans across multiple zone globally.
Important aspect is that all the availability zones and data center should perform toggle in sync with each other. We cannot have one feature on one system and adverse feature on different system.
We need some kind of global broadcast where we know all the features are same.
if (GLOBALLY_SYNCED) {
// Create Global Feature Toggle
} else {
// Default implementation
}
Currently we have three main cloud platforms, Amazon AWS, Microsoft Azure and Google GCP. We need to think of cloud independent way of changing toggle and provide security.
One of the option would be to use blue green deployment or use Kubernetes for orchestration.
