CAP theorem – the challenge

Imagine we have thousands of thousands of alerts (telemetry data) generated from IoT devices and we want to collect them to do some analysis, reporting or to create supporting tickets from the data we received? These alerts are sent over a network protocol, either through HTTPS, SMTP, TCP/IP or AMQP. The truth is that there will always be a latency receiving those messages. If you heard about the CAP theorem, it states that it is impossible for a distributed data store to achieve more than 2 out of these 3 guarantees:

I’ve been searching for a better solution to monitor our on-prem applications. I know these apps do their job just fine but I don’t like the way they stop working without my acknowledgement. One day a message came from the sales team asking “hey I won a quote but I didn’t see it in Navision”. I then had a look in the server and realized that the service somehow stopped working. So I restarted the service and it went back to normal. This is just a simple example of how we manage our apps manually. I’d like to have them automated. It’s time to enter Kubernetes.
