A custom template in the context of Microsoft Azure is often an Azure Resource Manager (ARM) template that you develop to specify and deploy your infrastructure as code. ARM templates are JSON files that specify the Azure resources that you will need to deploy, such as virtual machines, storage accounts, and networking components.
To deploy a custom template, type in custom template, and it will bring you to this window. Click on the Linux virtual machine.
Go to the resource group and give it a name. Enter your username and password. Everything else can remain as it is, depending on what your needs are. Review and create.
Always make sure you have created a resource group and then deploy.
Using ARM templates, you can deploy resources consistently across various environments, such as development, testing, and production. By implementing the same template across different stages of the development lifecycle, you can minimize errors and ensure that your infrastructure is uniform and reliable.
ARM templates are a powerful tool that enables the automation of resource deployment and management. With the help of tools like Azure PowerShell, Azure CLI, or Azure DevOps, you can easily automate the deployment and updates of your infrastructure. This not only saves time and reduces errors, but also ensures consistency across all your deployments.
By using ARM templates, you can easily scale your infrastructure by defining the desired state of your resources. This means that you have the flexibility to modify the template to add or remove resources as per your changing requirements without having to start from scratch. This makes it a highly efficient and time-saving process that can be done seamlessly.
This and many more are the reasons why we deploy resource templates in azure.
