Several options are available for getting started with MapR in Azure, with varying levels of effort and customizability.
|Deployment Option||Good for Users or Organizations Who Are/Have||Simplicity||Customizability||Licensing|
|Azure Marketplace||New to Azure or MapR
Full Access to Azure Account
|Pre-Defined Example||Some Experience with Azure or MapR
Some Limits to Azure Access
|Custom Pre-Defined Example||Extensive Experience with Azure or MapR
Complex Azure Security Policy and Roles
|Manual Deployment||Learning How MapR Deploys on Azure
Using Other Automation Tools Like Terraform or Ansible
There are two stages to deploying MapR in Azure:
These stages are kept separated in order to support the myriad ways in which users or organizations want to customize their cloud environment, or the way they deploy software. Many other software vendors try to control the entire cloud lifecycle, including provisioning of networks, to the dismay of customers with organizational policies that restrict network configuration, naming, and security policies.
For the first stage, deploying the Azure cloud environment, MapR provides pre-built utilities including the Azure Marketplace and pre-defined example Azure Resource Manager (ARM) templates. Because every company and environment is different, MapR also supports fully customized deployments, including modification of example ARM templates or manually provisioning a cloud environment from the Azure console. Power users can also automate cloud provisioning steps using another automation framework like Ansible or Terraform by following the steps listed in the manual deployment.
Once a cloud environment is deployed, the MapR Installer has an Azure plugin for deploying the Azure instances that will become the MapR nodes. Letting the MapR Installer control instance provisioning allows the MapR software to control the full lifecycle of the cluster, expanding the size on-demand, and in the future cycling through failed or underperforming instances. The MapR installer links to Azure Resource Groups, which serve as templates for instance configuration, allowing users to create instances using any available configuration and features that Azure supports.
The architecture diagram below shows the separation of duties between what the MapR-provided ARM Templates or Azure Marketplace entires perform, and what the MapR Installer Performs.
MapR provides an ARM template both directly and through the Azure Marketplace for deploying on Azure, along with several input variables for cluster customization. In some cases these templates are close, but not exactly appropriate for deploying a MapR cluster. This could be the case if an organization gives out restricted permissions, has specific networking rules, or any other specific customization needed.
In these cases, it may be appropriate to customize one of the MapR-provided ARM templates.
