VMware Hybrid Cloud Extension (HCX) Network Ports

I’d like to share a high-resolution network ports diagram of VMware Hybrid Cloud Extension service (previously known as HCX) that I have been working on this week. If you are considering using Hybrid Cloud Extension to solve your hybrid cloud challenges then this PDF would look great on any 4k monitor or perhaps printed for the office wall!

The first thing to notice is that HCX abstracts the underlying vSphere architecture which means that between the source and destination data centers, there is no direct communication (E.g. vMotion) between vSphere ESXi hosts.

VMware Hybrid Cloud Extension allows enterprises to overcome some of the challenges with moving to the cloud. Cloud Providers with the VMware Hybrid Cloud Extension (HCX) service can provide a true hybrid-cloud experience for workload portability, agility, disaster recovery and business continuity. This allows cloud providers to take the lead with hybrid cloud solutions, abstracting customer on-premises and cloud resources as one seamless cloud. No changes are required on the source network infrastructure, eliminating complexity for tenants of the cloud platform.

Don’t just think of Hybrid Cloud Extension as just a workload migration tool. One of the fundamental components of Hybrid Cloud Extension is the ability to provide a layer 2 extension of the customer data center to the cloud. This provides the basis for cross-cloud mobility allowing for any-to-any vSphere zero downtime migrations, seamless disaster recovery, and enabling hybrid architecture.

While migration is probably the most common use-case, there are many other challenges that are solved. Firstly, unlike professional services led migrations that often require costly and time-consuming workload assessments, cloud providers can provide an end-to-end service without the much of the additional complexity involved in the past. Another use-case allows migrations from legacy to next-generation environments, that are complex due to different versions of the underlying infrastructure (vSphere).

Cloud Momentum: VMware Cross-Cloud Architecture

We’re just days away from another VMworld in Las Vegas, and it’s going to be another amazing year, with a packed agenda crammed with sessions on our SDDC stack, including vSAN, NSX and vSphere, in addition to VMware on AWS and Cloud Foundation, all being my favorite topics at the moment. You’ll also find me discussing Cross-Cloud Architecture along with Adrian Roberts and Victor Sandoval, in the Ask the vCloud Air Network Cloud Experts [LHC1566PU] session which is on Monday at 12.30 so feel free to bring something to eat and drink for an hour of technical discussion!

I was also fortunate enough to be invited to the Virtustream Global Developer conference in Florida last week, and one of the topics I presented was titled ‘Cloud Momentum: Cross-Cloud Services and Architecture’. I must say that the team at Virtustream have some amazing talent so be sure to check them out at VMworld!

While I’m on the subject of Cross-Cloud architecture, there is a real challenge that I think customers are trying to solve. Firstly, cloud consumers have choice, but with that it’s inevitable that things don’t always turn out to be clear-cut. For example, let’s say we have a customer that wants to migrate their workload to the cloud. Most of their applications today have a traditional deployment with a database back-end, reliance on certain versions of Microsoft SQL and legacy dependencies which makes scale difficult. These traditional applications are not going to suit Azure, AWS or Google Cloud, but with VMware on AWS they can expand their existing vSphere infrastructure that they have on-premises, to an AWS data center.

As customers then introduce cloud native applications to their organization, they can take advantage of AWS services such as S3 and DynamoDB. What makes this relationship so unique is there traditional workloads can be placed side-by-side in the same AWS region and availability zone (AZ). This avoids network traffic having to occur over a VPN or Direct Connect, and they can keep the traffic internal to the AWS network. Taking things one step further, workloads can easily be moved using vMotion from their on-premises data center to AWS and visa-versa.

There will be much more to reveal at VMworld where you’ll hear the latest news on Cross-Cloud services and architecture.

See you in Las Vegas!
