As we have seen lately, Crossplane took over the world of Platform Engineering providing an absolutely easy and powerful way to build cloud native control planes.
But how does it work? How can I use it? What are the gains?
This brief post, which is created to be the initial one for a Crossplane series, aims to answer some basic questions for those who are still eager to use it.

Before we start this conversation, we assume you have knowledge on Kubernetes, Istio, Prometheus, Kiali, Jaeger and Grafana.
If you don't, you can check the official documentation by accessing the following links:
- https://kubernetes.io
- https://istio.io
- https://prometheus.io
- https://kiali.io
- https://www.jaegertracing.io
- https://grafana.com

By following this article, we are going to achieve such things:
- Install Istio (using revisions) to a Kubernetes Cluster
- Install Prometheus as an Istio addon so we can retrieve some service mesh custom metrics
- Install Kiali as an Istio addon so we can visualize our service mesh traffic and, if needed, manage and customize our traffic
- Install Jaeger as an Istio addon so we can monitor and inspect all our requests using tracing
- Install Grafana as an Istio addon so we can monitor everything that is going on through dashboards and charts
- Be able to perform Rolling Upgrades on Istio
