On-Demand NAT Network with On-Demand Load Balancer (In-line)

-

 During my experience with vRA 8.4 and NSX-V, I successfully implemented an On-Demand NAT Network with an On-Demand Load Balancer (In-line). This blog outlines the key aspects of this setup.


Existing NSX Edges in Our NSX-V

  • The environment contained multiple NSX Edge Gateways already configured.

  • The goal was to provision on-demand resources dynamically while integrating them seamlessly into the existing NSX topology.





Service Broker Catalog Items for One-Arm and Two-Arm Load Balancer in vRA 8.4

  • One-Arm Load Balancer: Configured for environments where a single subnet is sufficient.

  • Two-Arm Load Balancer: Utilized when separate front-end and back-end networks are required.

  • Service Broker catalog items were created to allow users to request the appropriate load balancer based on their application needs.



VM Request Based on User Inputs in vRA Catalog

  • Users could request VMs through the vRA catalog, specifying:

    • Number of VMs

    • Network requirements

    • Load balancing needs

  • vRA dynamically created the necessary networking and compute resources.



Successful Creation of On-Demand Load-Balanced VMs

  • VMs were deployed on On-Demand Logical Switches.

  • These switches connected to the On-Demand Edge Services Gateway (ESG), ensuring proper network segmentation.

  • The ESG provided NAT services while also acting as the Load Balancer.

  • Load Balancer rules were configured dynamically based on user inputs, ensuring efficient traffic distribution.










Conclusion

This implementation streamlined network provisioning by integrating vRA 8.4 Service Broker with NSX-V for dynamic NAT and Load Balancer setups. It provided users with a seamless way to request and deploy scalable, load-balanced applications. If you have any questions or insights, feel free to share!

Creating Snapshots for Unmanaged VMs in Aria Automation (vRealize Automation)

-
Image
 In multi-tenant environments powered by Aria Automation (vRealize Automation) , it's common for tenants to occasionally request snapshots for unmanaged virtual machines (VMs) . These unmanaged VMs exist in vCenter but are not provisioned through vRA and therefore fall outside the standard automation lifecycle. To address this need without impacting the broader environment or other tenants, we implemented a dedicated catalog item that allows tenants to safely request snapshots for their unmanaged VMs— securely, in isolation, and with auditability . Here’s how we approached this solution using a custom workflow and catalog configuration in Aria Automation. The Challenge Tenants may operate legacy or externally imported VMs that are not managed via vRA’s provisioning engine. Creating snapshots for these VMs traditionally requires manual intervention from infrastructure teams, which: Increases support overhead Introduces potential human errors Offers ...

Bulk import security policies into Palo Alto Networks firewalls

To bulk import security policies into Palo Alto Networks firewalls, you'll typically need to leverage the Palo Alto API or CLI with a script. I am using an Excel file (XLS), IP address validation, and mapping source and destination zones, for comprehensive solution to automate the process. 1. Input from XLSX File : You will first need to read the data from the XLS file. 2. Check for Existing Rules : Before creating new rules, you should check if similar rules already exist on the firewall. This could be done by comparing the rule names, source, and destination IPs, and zones. 3. Mapping Source Zone and Destination Zone : Ensure that the source and destination zones are correctly mapped according to your firewall configuration. 4. IP Address Validation : Before adding a rule, you'll need to validate that the IP addresses specified in the file are valid 📝  Flow Diagram  (Text Representation) Further Automation If you need enhancements or additional automation features , fee...

Automating Tag Creation & Assignment to VMs with vRA + vRO

-
Image
  Use Case Summary A user provisions a VM from vRA. Once the VM is deployed in vCenter , a vRO workflow is triggered via Event Broker subscription. The workflow: Checks if the Tag exists (using REST API to NSX-T). If not found, creates the Tag under the correct category. Assigns the Tag to the newly provisioned VM. This eliminates the need for manual intervention and ensures every VM is tagged correctly for policies, automation, and visibility . High-Level Flow VM Provisioning in vRA User requests VM with required details (e.g., Environment, Owner, Application). Event Broker Subscription After provisioning, vRA triggers a vRO workflow . vRO Workflow Actions Connects to vCenter using REST API. Checks if Tag exists. If exists → Skip creation. If not exists → Create new Tag under category. Assigns Tag to the VM. Result VM is provisioned with the right tags automatically applied . Flow Diagram Steps Start VM Prov...
