	There are many similarities between cloud native services and HVAC services, and it makes complete sense to adopt systems developed in the cloud industry if they can benefit the HVAC industry, and assist in saving carbon. When the disk space on a server is running low, services may become slow, and when a pump in a heat network has faulty bearings, hot water may cool down. Apart from the names involved, the systems used to catch and highlight problems are identical.

They are also far more evolved, covering everything down to engineer notification, and alarm escalation.

			Grafana has been developed to monitor and alarm cloud native systems, such as servers and online services. It is open-source as well as a managed service, providing all the functions required for maintaining critical services.

	* Freemium model, with a free forever plan alongside commercial packages		The cloud landscape requires continued up-times, monitoring of containers and clusters, and advanced alarm routing with escalation of problems as they occur to prevent any loss of services.
