L07 - SDDC Migration with HCX - Configure HCX Connect & Service Mesh (Part 1)

Updated on

Introduction

VMware Cloud on AWS provides a reliable, elastic, and highly scalable solution for customers who want to extend their workloads into the cloud.

However, when it comes to migration or bi-directional workload mobility, software and network incompatibilities between on-premises and cloud environments can complicate your migration process.

VMware Hybrid Cloud Extension (HCX) helps overcome those challenges by building an abstraction layer on top of existing site-specific implementations, allowing you to extend their networks and environments to the cloud seamlessly without the need for extensive reconfiguration and upgrades.

Here are some key benefits of HCX:

  • Ability to migrate workloads across different versions of vSphere (6.0 or later).
  • WAN optimization, compression, and de-duplication enable high throughput for faster migrations.
  • Network extension enables stretching layer 2 networks between on-premises and VMware Cloud on AWS without the need for complex network reconfiguration. Virtual machines (VM) can be moved between on-premises and cloud environments with no need the change or re-assign IP addresses.

HCX is a software-as-a-service (SaaS) offering, available at no extra cost for VMware Cloud on AWS customers.

The HCX solution is built out of several component services, each supporting a specific function within the overall solution.

  • HCX Enterprise Manager: System management component on the on-premises side, which is always deployed as a “source.”
  • HCX Cloud Manager: System management component on the cloud side and is always deployed as “destination.”
  • HCX-IX Interconnect Appliance: Provides replication and vMotion-based migration capabilities.
  • HCX WAN Optimization Service: Provides improved network performance by using techniques such as de-duplication and compression to help speed up migrations.
  • HCX Network Extension Service: Provides layer 2 extension capabilities, enabling VMs to migrate between on-premises and cloud without the need to re-IP.

HCX Use Cases

Older vSphere Versions

HCX allows migrating VMs from older versions of vSphere (6.0 or later) to VMware Cloud on AWS. Hosts in VMware Cloud on AWS are automatically patched, updated, and are thus likely to be running the latest (or near) version of vSphere software. This eliminates the need for customers to perform time-consuming system upgrades in order to prepare for migrations.

Bulk Migrations

In certain situations, customers may want to migrate workloads out of their current data centers in a “lift-and-shift” manner. An example of this is if you have an upcoming lease expiration on the hardware or data center facility. In this situation, when there’s not enough time for migration planning and execution, HCX can help customers migrate thousands of VMs simultaneously with no downtime. HCX, with WAN optimization services, can provide a high throughput connection over which on-premises networks can be extended into the cloud.

Heterogeneous Network Environments

Typically, your current on-premises network environment is one of the most important considerations in the migration planning process. Whether you have VXLANs, NSX for vSphere, NSX-T, or No NSX at all, each of these factors can complicate your migration plan. The good news is that HCX works by abstracting out the underlying network implementation, extending your networks from on-premises to the cloud seamlessly without the need for complex and time-consuming network re-architecture.

Slow/Sub Optimal Network Connectivity

A live vMotion across WAN with vSphere is sensitive to network bandwidth. Typically, a connection speed greater than 250 Mbps is required, but with its advanced WAN optimization capabilities, HCX can migrate live VMs over much slower connection speeds of around 100 Mbps per migration.

In this lab, we will walk through the deployment of HCX, site pairing, Service Mesh configuration Plus migration, and Network extension.

TASKS

Task 1 - Configure access to HCX from On-Premises

 

HCX has been successfully deployed in the cloud, let's try configure access to it via the SDDC management Gateway. HCX like all management components (such as vCenter) are protected by the Management Gateway, and until an allow rule is put in place it will be inaccessible.

  1. From the VDI desktop access your SDDC, Using your SDDC Student account
  2. Log in as:
    • vmcexpert{1|2|3}-##@vmware-hol.com (where ## is your student number) i.e [email protected]
    • VMware1!
  3. Click View Details
  4. Select the Integrated Services tab
  5. Click Open HCX
  6. In the new browser tab Click Open HCX in your SDDC Tile   Note: We expect this to fail because we need to define a firewall policy through the Management Gateway to allow access to HCX.
  1. Back at the SDDC Console Select the Settings tab
  2. Expand the HCX FQDN Section
    Confirm that the Resolution Address is set to Public, if not
  3. Click Edit
  4. In the Resolution Address section select Public IP <x.x.x.x> from the drop-down
  5. Click Save
  6. Record the Public IP address of HCX
    You will update the on-premises HCX Manager host file with these settings, if needed.

 

  1. In the VMware Cloud on AWS portal click the OPEN NSX MANAGER button
  2. Click ACCESS VIA THE INTERNET to connect to NSX Manager UI
  3. Choose Security tab
  4. Click Gateway Firewall
  5. Click Management Gateway
  6. Click Add Rule twice to add two new rules
  7. Configure the Rules as follows:
    1. RULE 1
      • NAME: HCX Outbound
      • Sources: HCX
      • Destinations: On-Prem Mgmt-Net
      • Services: Any
      • Action: Allow
    2. RULE 2
      • NAME: HCX Inbound
      • Sources: On-Prem Mgmt-Net
      • Destinations: HCX
      • Services: Appliance Management, SSH, HTTPS
      • Action: Allow
  8. Click Publish
Task 2 - Access HCX Cloud

Now, let’s try accessing HCX again. From the On-Prem Control Center, access your SDDC Console

  1. Click the Integrated Services tab in your SDDC VMC on AWS console
  2. Click Open HCX
  3. In the new Browser tab, click Open HCX in your SDDC Tile
    NOTE: If opening HCX still fails, first try to close the Chrome browser and reopen it to clear any cache. Then verify that you did not forget to add 192.168.110.0/24 and your VDI Desktop public IP to the On-prem MGMT NET group back in Lab #4 Task 2.3.
  4. Back in your SDDC Console, Select the Setting tab
  5. Copy the vCenter Username and Password (We will use this to log into HCX)
  6. Back in the HCX Login Tab
  7. Login with the Username and Password recorded earlier
Task 3 - Configure HCX On-Premises

Now that HCX has been deployed in the cloud the next step is to download the HCX appliance On-Premises, import it onto an ESXi host, and configure it.

NOTE: In this lab environment the Appliance has already been imported, so we’ll move to configure it.

The first thing we will do is ensure the on-premises HCX Manager can resolve the IP of the Cloud HCX Manager, for this we will edit the host file of the On-premises HCX manager
