Today I took the Xendata Cloud File Gateway out for a spin… Why? This little piece of software allows a windows volume to be extended by an Azure Storage Account. And from a technical level, we are talking about blob storage here. So you can leverage hot & cold storage, and even archive storage in the long-term. Imagine that huge exploding file server? Suddenly we can extend our typical Windows File Server with an seamlessly unlimited cloud tier. Whoppah!
Let’s take a look shall we!

For those who have been test driving the autoscale on the virtual machines scale sets… You probably have run into the situation where you wanted to go beyond the quickstart examples!
A quick tip on how to find out which Metrics are available for your autoscaling ;
So now you have the list of metrics which you can use to tweak the vmss-autoscale templates (for example ; https://github.com/Azure/azure-quickstart-templates/blob/master/201-vmss-ubuntu-autoscale/azuredeploy.json )
Today we’ll be building further on the steps we took in the previous post ; “Autoscaling Docker hosts on Azure with Virtual Machine Scale Sets & Rancher“.
What will we be doing?
- Deploy our VMSS with a scale-up & a scale-down configuration
- Stress our VMSS so it will scale-up
- Remove the stress so our VMSS will scale-down

A while back Mark Russinovich announced the public preview of the “Virtual Machine Scale Sets“;
VM Scale Sets are an Azure Compute resource you can use to deploy and manage a collection of virtual machines as a set. Scale sets are well suited for building large-scale services targeting big compute, big data, and containerized workloads – all of which are increasing in significance as cloud computing continues to evolve. Scale set VMs are configured identically, you just choose how many you need, which enables them to scale out and in rapidly and automatically.
So here we have a cloud service that would enable us to autoscale our hosts in terms of the load of the underlying systems. Now imaging combining this feature with Docker… I don’t know about your, but I’m excited about this premise! When combining this with Rancher, you could make your own Containers-as-a-Service (CaaS)! Today we’ll be delving into the matter to see how to implement this…
A quick extract from the ARM Resource Visualizer… when loading the ARM Template I have prepared for this deep dive.
