Introduction

All DevOps teams need different kinds of environments during the realization of a software system. The availability of environments is of great importance for the speed of delivering that piece of value for the business. Azure DevTest Labs is a service provided by Microsoft Azure which provides functionality for managing environments that contain Azure Virtual Machines. It helps developers and testers to quickly create environments in Azure whilst minimizing waste and controlling cost. Developers can also use artefacts to quickly deploy and configure applications. By using custom images and formulas, developers can save virtual machines (VMs) as templates, and easily reproduce them across the team. DevTest Labs also offers several configurable policies that lab administrators can use to reduce waste and manage a team’s environments.

Scenarios

Azure DevTest Labs is a solution for fast, easy and agile, dev-test environments in Azure. Azure DevTest Labs can be used to implement many key scenarios:

• For developers (to host development machines) – developers can quickly provision their development machines on demand and customize whenever needed.
• For test environments (to host machines for testers) – Testers can test the latest version of their application by quickly provisioning Windows and Linux environments using reusable templates and artefacts.
• For training education – create a lab where you can provide custom templates that each trainee can use to create identical and isolated environments for training

Core Capabilities of DevTest Labs

A lab is an infrastructure that encompasses a group of resources, such as Virtual Machines (VMs). It is created from Azure Marketplace. Azure VMs give you the flexibility of virtualization, although you still need to maintain the VM by performing certain tasks, such as configuring, patching, and installing the software that runs on it. Once created, you can:

1. Connect to the VM
2. Start
3. Stop
4. Delete
5. Apply artefacts

Also, you can manage configurations and policies such as allowed virtual machine sizes, virtual machines per user, virtual machines per lab, auto shutdown, auto start, manage repositories, marketplace images or custom images, and also you can monitor the cost.

New Features of DevTest Labs

• Managed Disks Support – now Azure DevTest Labs supports Managed Disks in all labs, including VM OS disks, data disks, and custom images. Managed Disks helps you manage multiple storage accounts for a large number of VMs. All managed-disk resources are automatically managed by Azure instead of your own storage accounts, which simplifies scalable VM deployments and management.

• Claimable VMs – Lab admins can prepare VMs and put them in a shared pool, and lab users can pick a working VM from the pool whenever they need one.

• Create identical VMs in a batch – Now you can create multiple identical VMs in Azure DevTest Labs from the same VM image and artefacts all at once. You just need to provide a number of the VM instances.

• VM auto-expiration – you can set an expiration date by specifying a date on which the VM automatically will be deleted.

• Minimize public IP addresses – Azure DevTest Labs lets lab VMs share the same public IP address in order to minimize the number of public IP addresses required to access your individual lab VMs.

Conclusion

Azure DevTest Labs is an Azure service that lets you quickly create environments in Azure while minimizing waste and controlling costs. DevTest Labs is useful any time you require dev or test environments and want to reproduce them quickly or manage them by using cost-saving policies. DevTest Labs provides a lot of benefits in creating, configuring, and managing developer and test environments in the cloud.
