vCloud Extender-Part 1:Introduction

Posted on 29-09-2018 by Manish Jha

What is VMware vCloud Extender?

VMware vCloud Director Extender creates a hybrid cloud environment between an end-user on-premise data center, and a multi-tenant vCloud Director environment. vCloud Extender is replacement for vCloud Connector and this product was released soon after vCloud Director 9.0 was announced.

What does vCloud Extender offers?

vCloud Extender allows customers to migrate workloads from On-prem vSphere environment to a vCloud Director based Public Cloud. The two migration methods that are available with vCloud Extender are the cold and warm migration and I will talk about these methods in detail in upcoming post of this series.

One more exciting feature that vCloud Extender offers is to stretch an on-prem Layer 2 network to cloud. This feature helps customer to achieve their “Cloud Migration” objective without much hassle as you no longer need to Re-IP workloads that are migrating to cloud.

You do not need to have on-prem deployment of NSX to stretch a layer 2 network to cloud but without on-prem NSX, you are limited to extending only vLANs to VXLAN on the cloud side.… Read More

In last post of this series we paired the two vCloud based cloud instances. Now its turn to test the DR capabilities offered by vCAV-C2C.

If you are not following along this series, then I recommend reading earlier posts of this series from below links:

1: Introduction to vCloud Availability for Cloud-to-Cloud DR

2: vCAV-C2C-POC Deployment

3: Site Pairing

To start testing DR operations, connect to https://VCAV-FQDN:8443 and login with tenant credentials (uname@orgname) and navigate to Paired Clouds.

By default your Site-B will show as unauthenticated. Click on the gear button to enter credentials.

Enter Org name of Site-B and the Org User credentials. Click on Authenticate.

Now both sites will show as authenticated.

Perform the same operation by connecting to VCAV appliance of Site-B and adding Org/User details of Site B and make sure both sites are showing as authenticated.

Once both sites are authenticated, navigate to DR-Workloads tab and click on Discovery

Select source site from where replication will be initiated.… Read More

vCloud Availability for Cloud-to-Cloud DR-Part 3: Site Pairing

Posted on 25-09-2018 by Manish Jha

In last post of this series we configured the vCAV-C2C appliance for both Site A & B. In this post we will learn how to perform site pairing so that tenants can start replicating workloads between 2 cloud instances.

If you are not following along this series, then I recommend reading earlier posts of this series from below links:

1: Introduction to vCloud Availability for Cloud-to-Cloud DR

2: vCAV-C2C-POC Deployment

To perform site pairing, login to vCAV-C2C appliance of site A by connecting to https://VCAV-FQDN:8046 and navigating to Sites > New Site and enter IP/FQDN of VCAV appliance of Site B.

Accept the SSL certificate.

If your configuration is correct, you will see a succesful site pairing message.

Under Sites > Show all sites, you can see the pairing information.

And that’s it for this post. In next post of this series we will perform replication of workloads across 2 cloud.… Read More

vCloud Availability for Cloud-to-Cloud DR-Part 2: POC Deployment

Posted on 24-09-2018 by Manish Jha

As discussed in last post, we can configure all roles present in vCAV-C2C in a single appliance for Lab/POC deployment. In my lab I am going ahead with small deployment to have a general understanding of this product before doing distributed deployment.

In my lab I have 2 sites and each site is configured with following components:

1: vSphere/vCenter Server 6.5 U2

2: vCloud Director 9.0

3: VMware NSX 6.3.6

vSphere and vCD is fully configured and Org/Org vDC’s are in place n both sites with external network etc configured.

Let’s start the deployment with Site-A.

Deployment of VCAV-C2C appliance is straight forward and steps are shown in below slideshow.

Once appliance deployment completes and it boots up, it will give you information on how to connect to appliance for further configuration.

vCloud Availability for Cloud-to-Cloud DR-Part 1:Introduction

Posted on 23-09-2018 by Manish Jha

VMware vCloud Availability for Cloud-to-Cloud DR is the most recent addition to the VMware Cloud Provider Platform portfolio. It was originally introduced in May 2018, and it delighted service providers that have long desired a VMware native Cloud to Cloud DR solution for vCloud Director-based clouds.

What is vCloud Availability for Cloud-to-Cloud DR (vCAV-C2C)?

VMware vCloud Availability for Cloud-to-Cloud is a solution for disaster recovery between two instances of vCloud Director. The concept of cloud-to-cloud DR is not new, however, VMware did not have any solutions for vCloud-based clouds. vCAV-C2C bridges this gap and enables VMware Cloud Providers to use their current vCloud Director installations to deliver disaster recovery services, such as replication and failover capabilities for workloads at both the VM and vApp levels.

The following are the main capabilities of the vCAV-C2C solution:

1: Replicate and recover vApps/VMs between two vCD instances for migration, DR, and planned migration use cases.… Read More
