Multi-Tier Bitnami Grafana Stack on Azure

After seeing some tweets about Bitnami’s multi-tier Grafana Stack, I decided to give it a go. On the page describing the Grafana stack, there are several deployment offerings:

I decided to use the multi-tier deployment, which deploys multiple Grafana nodes and a shared Azure Database for MariaDB.

On Azure, the Grafana stack is deployed via an Azure Resource Manager (ARM) template. You can easily find it via the Azure Marketplace:

From the above page, click Create to start deploying the template. You will get a series of straightforward questions such as the resource group, the Grafana admin password, MariaDB admin password, virtual machine size, etc…

It will take about half an hour to deploy the template. When finished, you will find the following resources in the resource group you chose or created during deployment:

Let’s take a look at the deployed resources. The database back-end is Azure Database for MariaDB server. The deployment uses a General Purpose, 2 vCore, 50GB database. The monthly cost is around €130.

The Grafana VMs are Standard D1 v2 virtual machines (can be changed). These two machine cost around €100 per month. By default, these virtual machines have a public IP that allows SSH access on port 22. To logon, use the password or public key you configured during deployment.

To access the Grafana portal, Bitnami used an Azure Application Gateway. They used the Standard tier (not WAF) with the Medium SKU size and three nodes. The monthly cost for this setup is around €140.

The public IP address of the front-end can be found in the list of resources (e.g. in my case, mygrafanaagw-ip). The IP address will have an associated DNS name in the form of
mygrafanaRANDOMTEXT-agw-dns.westeurope.cloudapp.azure.com. Simply connect to that URL to access your Grafana instance:

Naturally, you will want to access Grafana over SSL. That is something you will need to do yourself. For more information see this link.

It goes without saying that the template only takes care of deployment. Once deployed, you are responsible for the infrastructure! Security, backup, patching etc… is your responsibility!

Note that the template does not allow you to easily select the virtual network to deploy to. By default, the template creates a virtual network with address space 10.0.0.0/16. If you got some ARM templating skills, you can download the template right after validation but before deployment and modify it:

Conclusion

Setting up a multi-tier Grafana stack with Bitnami is very easy. Note that the cost of this deployment is around €370 per month though. Instead of deploying and managing Grafana yourself, you can also take a look at hosted offerings such as Grafana Cloud or Aiven Grafana.
