quasardb on Microsoft Azure

9 years ago

Getting your hands on quasardb has never been that easy. With just a few mouse clicks you can deploy your own quasardb server in Microsoft Azure.

A quasardb Virtual Machine (VM) image is now available for free on VM Depot. It includes a free license limited to one node and everything you need to test quasardb.

How to create your quasardb VM

Deploying the virtual machine is very straightforward and take about 15 minutes.

Ready? Let’s go!

  1. Open vmdepot.msopentech.com.
  2. Type “quasardb” in the search box.
  3. Click “Create Virtual Machine”.

If it’s the first time you use VM Depot, it will ask you to link your account with your Azure subscription.
If you don’t have an Azure subscription, there is a “Free Trial” for one month.

OK, now that your quasardb VM is running, let’s take a quick tour of what you can do…

Checkout quasardb web console

Go to http://yourservicename.cloudapp.net:8080/view/.

Pipe the result of a command:

1
$ ls -l | wc -l | qdbsh put num_files

$ tar czf – /etc | qdbsh update etc

Extract a folder:
