Create VMs in Availability Sets using Resource Loops

Deploy to Azure		 Create 2-5 VMs in Availability Sets using Resource Loops. The VMs can be Unbuntu or Windows with a maximum of 5 VMs since this sample uses a single storageAccount
Multi VM Template with Managed Disk

Deploy to Azure		 This template will create N number of VM's with managed disks, public IPs and network interfaces. It will create the VMs in a single Availability Set. They will be provisioned in a Virtual Network which will also be created as part of the deployment
CentOS/UbuntuServer Auto Dynamic Disks & Docker 1.12(cs)

Deploy to Azure		 This is a common template for creating single instance CentOS 7.2/7.1/6.5 or Ubuntu Server 16.04.0-LTS with configurable number of data disks (configurable sizes). Maximum 16 disks can be mentioned in the portal parameters and maximum size of each disk should be less than 1023 GB. The MDADM RAID0 Array is automounted and survives restarts. Latest Docker 1.12(cs3) (Swarm), docker-compose 1.9.0 & docker-machine 0.8.2 is available for usage from user azure-cli is auto running as a docker container. This single instance template is an offshoot of the HPC/GPU Clusters Template @ https://github.com/azurebigcompute/BigComputeBench
