What you always wanted to know about Compute Qloud™ but never dared to ask

What is Compute Qloud™?

The best cloud computing service in the world! 😉

As opposed to cloud storage, with Compute Qloud™ you have the ability to manage virtual machines, also called instances, to handle the computing processes you need, such as running applications.

They’re called ‘virtual’ because they’re dynamically created and destroyed within a larger pool of hardware resources. Traditionally, a server consists of fixed hardware parts regardless of workload. With Compute Qloud™, the server has access to the same hardware, but only using what’s needed, and you only pay for what you used.

For all intents and purposes your virtual machines behave like (and are treated as) real, physical servers.

What’s the difference between a Compute Qloud™ VM and a VPS?

Nothing is apparent on the front end.

Its differences are mostly on the back end, but overall, these differences are not visible to you as a user.

Where are the instances physically located?

All of our compute nodes are currently located in two Icelandic data centers. Our US availability zone will be located in Seattle, through our partnership with Digital Fortress.

When the US availability zone opens in June, you’ll have the option to choose where you want your VMs to be stored.

How much does it cost?

It depends on how you use it. You can play with our pricing calculator to estimate costs for your needs. Bandwidth to your VMs is free, as well as the first terabyte of traffic that you use.

Is there a free trial?

Sorry, we no longer offer a free trial.

Is it secure?

Absolutely. You can use your own ssh keys or get a new one with a few clicks in the dashboard.

The default root/super user password for a server is stored encrypted in GreenQloud’s database – only you can decrypt it, using your private key.

Your account is completely isolated from other accounts in our hardware network switches so you get your own VLAN at no extra cost.

Our built-in security groups make it easy to template firewall rules for reuse. By default all new VMs are inaccessible from the internet, allowing you to open only the ports necessary for your needs.

How do I create an instance?

Our handy dashboard will do the heavy-lifting for you.

In a few clicks you can set up a new instance, assign security groups and do all the high-level stuff for your servers without touching the command line.

You can also read our introductory article on how to get started with your shiny new virtual machine.

Can I set up load balancers to ensure higher availability?

Absolutely. For your existing instances you can set up load balancers from the dashboard in a few clicks. If you need to duplicate a particular instance, let us know and we’ll do the heavy lifting for you.

Is there a limit for the number of running VMs?

By default you can have a maximum of five VMs running with five reserved IP addresses. You can request the limit to be raised at any time, by sending us a ticket.

Can I change security groups?

Once set, you can’t change the security group your instance belongs to, so make sure you double-check these settings.

You can have an unlimited number of security groups and best practice is to create a separate security group for each VM (or task served by a group of VMs) before spinning up an instance.

Can I use Storage Qloud™ as a disk volume with Compute Qloud™?

Yes you can, but not as the root volume. After you created your instance, you can attach Storage Qloud™ buckets as mounted filesystems to store your files. We wrote a nifty how-to article on it to help you out.

Can different instances communicate with each other?

They sure can. To understand how you can facilitate that, and in general how GreenQloud’s network model works, refer to our excellent article in the community forums.

How can I access the servers?

We offer full ssh root access and a browser-based noVNC terminal.

You can also install a server management control panel, such as Ajenti, to manage your VM.

Unfortunately, cPanel is not supported on GreenQloud. If you are interested in potential reseller options using WHM, please let us know and we can connect you with an appropriate contact for discussion.

How do I scale up an instance?

Click on the ‘cogwheel’ next to your instance specs – you’ll be able to scale it upwards.

How do I scale down an instance?

Send us a ticket! We’ll take care of that for you and let you know when it’s ready.

I need to backup my VM – can I take a snapshot of the instance?

For sure. Requesting a snapshot is easy – just click on the camera icon next to the instance name in the console.  This will send us a ticket and we’ll take the snapshot for you, then let you know when it’s ready.

Can I monitor my servers?

Yes! Our award-winning dashboard includes live graphs for CPU and network load, both for your account and each VM individually.

You can also check how much you’re saving in CO2 emissions by using our Truly Green™ services and share these to social media.
