1. Introduction
There is no perfect software solution for every user and every application.
What works for one person may be too much or too little, too simple or too complex for another.
That is why Checkmk is available in a number of different editions.
These differ above all in their range of features and suitability for specific areas of application.
In the following short article we would like to introduce 
Checkmk Cloud, one of the commercial editions.
2. Overview of Checkmk Cloud
Its content is based on Checkmk Enterprise, but it additionally provides extensive cloud functions.
This makes Checkmk Cloud particularly valuable for users whose hosts are located in a cloud and who also want to set up their entire monitoring in a cloud.
Support when moving applications and processes to the cloud, i.e. in so-called lift and shift scenarios, has already been integrated into all Checkmk editions — which simplifies the implementation of a monitoring of Amazon Web Services (AWS), Microsoft Azure and the Google Cloud Platform (GCP). In addition, Checkmk Cloud also provides cloud-specific check plug-ins. In this way you can continue to use Checkmk Enterprise when transitioning from a data center to a cloud. If you would subsequently also like to use the SaaS and PaaS products that a cloud can additionally provide, you can upgrade to Checkmk Cloud.
3. Additional functions with Checkmk Cloud
The key features of Checkmk Cloud that differentiate it from other editions:
Checkmk Cloud is available through the Microsoft Azure and AWS marketplaces.
Advanced check plug-ins:
Checkmk Cloud includes additional cloud-specific check plug-ins for monitoring Amazon Web Services (AWS), Microsoft Azure and the Google Cloud Platform (GCP).Cloud-specific dashboards:
In Checkmk Cloud, there are specific dashboards for AWS, Microsoft Azure and GCP.Configuration of a push agent:
In all Checkmk editions, the Checkmk server initiates communication with a host and requests the data from the Checkmk agent — in the so-called pull mode. With Checkmk Cloud you can additionally use the push mode. You configure the push mode in the properties of a host, in the section on monitoring agents.Auto-registration of hosts:
In Checkmk Cloud, you can have hosts created automatically that have a Checkmk agent installed. This includes registering the agent with the Checkmk server, establishing a TLS-encrypted connection, creating the host, performing a service discovery and activating the changes, so that the host is added to the monitoring environment — all fully automatically. Auto-registration works for pull and push agents.
Note: In the Checkmk user interface, elements that only exist in Checkmk Cloud are indicated by the (Cloud Edition) suffix, e.g. rules, dashboards or parameter values.
4. Upgrading to Checkmk Cloud
You can test Checkmk Cloud without obligation, because it is not limited in the first 30 days. By entering a license key after 30 days at the latest, you can then use Checkmk Cloud without limitations.
To upgrade from one of the other editions to Checkmk Cloud, follow the upgrade description.

Agent Bakery |
In Checkmk Cloud you can additionally use the Agent Bakery to provide agent packages with a configuration for auto-registration. The rule for the Agent Bakery is named Agent controller auto-registration (Cloud Edition). These packages perform registration automatically after installation. |
Agent registration permissions |
