Create an ECS Linux instance in OpenStack based Fusion Cloud

What is an ECS?

ECS stands for Elastic Cloud Server that facilitates computing needs for applications, technically it is a virtual machine in cloud environment.

Steps to create an ECS:

  1. Determine the resource required like cpu, memory and storage.
  2. Determine the Operating System images with required version.
  3. For networking create a VPC if not already exist or choose one from the list available.

Let’s Dive in:

  1. Login to the VDC or the user console.                                                                          
  2. From the dashboard top choose the Apply for ECS.                                                             
  3. When prompted select Apply Now.                                                                       
  4. Supply the ECS basic information.
    1. Supply the ECS name , it is automatically loaded though.
    2. Select the AZ(availability zone) if you are offered multiple otherwise a single zone is selected.
    3. Choose the ECS type if there is more than one.
    4. Choose the vCPU as required for your application.
    5. Choose the Memory as required for your application.
    6. Choose from Image Type : if you have private image of your OS available created by you choose the Private Image; otherwise choose the Public Image supplied by the cloud service provider.
    7. Choose the Image: Select the Operating system you need and then the available image against it.
    8. When you like to avail backup or disaster recovery service choose the Same Storage to Yes.
    9. Choose the Disk: This is system Disk and the size of the system disk depends on the image you chose which is shown at right most. Optionally you could add Data Disk at this stage or can create later on.
    10. Choose Usage Duration: default is Unlimited.                                                 
    11. Supply the ECS network information.
      1. Choose the VPC from the list available.
      2. Choose the Security Group from the list available.
      3. Choose the NIC, Primary NIC subnet from the list available. If you do not do Self-assigned Ip Address it will be automatically allocate one from the available ip addresses. You could optionally add a Extension NIC at this stage if you like.
      4. Choose the EIP if you need Internet access for the ECS. Automatically Assign will assign one from the available pool and you can Specify one from the pool manually by View EIP.       
    12. Perform other configurations and select Apply Now.                                      
    13. Review the resource details and Submit; if you need to change anything select Previous. 
    14. It will redirect you to the Elastic Cloud Server page and the new ECS status will be Creating, hit refresh if needed.                                                                                                                                     
    15. When it finished creating the status will be Running.                                     
    16. Now connect to the newly created ECS by selecting Remote Login.             
    17. This will open a new tab and redirect you to the Login GUI or Shell depends on your image.  
    18. Cheers, Happy computing. 🙂
