Creating virtual machines with Azure for high availability of Talend Administration Center

This section explains how to create Azure Virtual Machines with a Linux Redhat 7.3.

Procedure

  1. Go to the Azure Portal: https://portal.azure.com/
  2. Click Add on the Virtual Machines tab.

    For more information on how to create an Azure virtual machine, see Create a Windows virtual machine with the Azure portal.

  3. Choose Redhat in the list proposed by Azure, and select version 7.3.

    You can choose another operating system according to your needs

  4. Configure the basic settings as follows.
    Field Value
    Name

    Define the name of your virtual machine, aleducTac1, for example.
    VM disk type Define the type of disk: SSD or HDD.
    User name Define the user name you want to use to login to the virtual machine.
    Authentication type Define the type of authentication: SSH public or Password.
    Resource group

    Select your resource group.

    If you do not have an existing resource group, create one. This allows you to manage your Azure environment easily.
    Location

    Select the location.

    Adapt the location to your area.
  5. Select the size of your virtual machine, in this case, choose a small size.

    This section allows you to choose the number of CPU and the size of the memory. The size depends on your environment. For more information, see Sizes for Windows virtual machines in Azure.

  6. Configure the optional features as follows.
    Field Value
    High Availability

    Choose or create an Availability Set.

    By creating an availability set, Azure ensures that the virtual machines run across multiple Azure infrastructures (physical servers, storage units, etc.).
    Virtual network

    Keep the default value.

    The virtual network groups the virtual machines that you connect together.
    Public IP address

    Define the Public IP address. In this case, create a static IP.

    You need a static IP because Talend Administration Center connects to the Azure MySQL database where you set the IP.
    Network security group

    Define the Network security group. All the virtual machines needed for your architecture use the network security group (NSG).

    The network security group contains all the security of your architecture (inbound security rules, outbound security rules). For more information, see Filter network traffic with network security groups.
    Diagnostics storage account Select the Azure storage where diagnostics data will be stored.
  7. Click Create to create and deploy your virtual machine once Azure validates the configuration.

Results

The virtual machine is now running.
