Enterprises worldwide rely upon VMware’s virtualized infrastructure platform. As these firms flip to public cloud for its elasticity, economics, and highly effective providers, many are investigating how their VMware workloads might be a part of this transition. All the foremost public cloud suppliers have launched VMware Cloud verified providers as a part of their choices. These options begin with the identical software program, however cloud suppliers have taken completely different approaches to provisioning, connectivity, and administration to combine VMware into their platforms.

How related are the VMware Cloud verified providers within the public clouds, and what are their operational variations? If an organization runs VMware on-premises and desires to increase or substitute a knowledge middle, can they use the identical expertise, processes, and instruments when their Software program-Outlined Information Facilities (SDDCs) are a part of a public cloud?

The CTO Advisor investigates

To reply these questions, analyst and guide Keith Townsend, also called The CTO Advisor, assembled a group to carry out hands-on testing in three public cloud providers based mostly on the VMware Cloud platform—vSphere, vSAN, and NSX—and to doc their expertise.

The CTO Advisor group examined Oracle Cloud VMware Solution, VMware Cloud on AWS, and Google Cloud VMware Engine. (Azure VMware Answer was nonetheless in preview as they performed this examine.) The conclusion? Oracle affords a markedly completely different method than the others, one that’s nearer to “just the VMware you already know” within the cloud.

Because the Oracle Cloud group designed and constructed the Oracle VMware answer, a transparent precedence was the power of a VMware group to make use of their current expertise and tooling. For extra context in regards to the answer and our design rules, see the Announcing the Global Availability of Oracle Cloud VMware Solution weblog publish.

The CTO Advisor report discusses how firms need to use public clouds for his or her VMware workloads. Particularly, the report examines widespread enterprise makes use of, akin to catastrophe restoration, knowledge middle enlargement and migration, and hybrid cloud architectures that depend on each on-premises and cloud-based providers. The state of affairs used within the report for this testing relies on real-world considerations: a pandemic response that requires a fast shift of current apps and desktops to the cloud, which in flip requires an enlargement of capability each in knowledge middle assets and wide-area connectivity.

The testing state of affairs

The members of the CTO Advisor group have deep expertise as VMware admins and infrastructure architects. The CTO Advisor constructed an precise knowledge middle in Chicago, and stuffed it with servers, storage arrays, and switches. In consequence, the report outcomes are based mostly on precise deployments and assessments executed by the CTO Advisor group, and never on theoretical architectures constructed out on paper.

The group designed and deployed an answer that linked their knowledge middle to every of the general public clouds they have been testing. They then provisioned an SDDC consisting of VMware vSphere, vSAN, and NSX put in on a cluster of three servers, and linked it to the VMware SDDC of their on-premises knowledge middle.

On this state of affairs, the group instantly wanted extra capability to accommodate a newly distant workforce utilizing digital desktops. Utilizing the connection to every cloud, they rapidly migrated and redirected parts of their current digital desktop infrastructure from the Chicago knowledge middle to the VMware cluster in every cloud. In addition they examined migrating on-premises VMware-based functions to the cloud. Alongside the best way, they examined their current operational procedures and instruments on this new surroundings in areas like networking, administration, compliance, and knowledge safety.

How Oracle Cloud in contrast

When the group examined failover by bringing down an ESXi server with operating workloads, that failover state of affairs highlighted the variations among the many public cloud options as a result of it labored solely on Oracle Cloud, which is the one answer that provides full vSphere and vCenter entry to VMware directors. The opposite public clouds don’t give this sort of full entry to the core VMware software program and the naked steel servers it runs on. On Oracle Cloud, the group might additionally management the variations and patch ranges of the VMware software program they have been utilizing, and so they might use different instruments like VMware SRM in the identical manner they will on-premises.

Different variations appeared in testing on the cloud platforms, and the report explores how they might have an effect on operations for groups who’ve been operating VMware on-premises. Though the VMware platform was related in each case, there have been variations in how the VMware cluster interacted with the remainder of the general public cloud surroundings. These variations had an affect on the operators within the assessments, who needed to adapt to the connectivity and administration capabilities of every particular person cloud.

The CTO Advisor report notes, “For example, Oracle Cloud Infrastructure highlights its ability to support existing enterprise applications and operations. Oracle Cloud VMware Solution carries this theme throughout the technical solution by providing bare-metal access to the user. We like to call it ‘Expert VMware Mode’ in the public cloud, because it allows experts to access all platform features.”

The report concludes, “The value of this solution is that there is a minimal learning curve. It’s a customer’s VMware implementation on top of Oracle’s hardware—gated, secured, managed, and controlled by your existing VMware staff, yet housed on OCI’s hardware. The flattened learning curve means the customer can be up and running as soon as the data pipe is in place. Wizards exist to build the SDDC implementation, the Horizon View architecture, and many other components of the required VMware solution, practically out of the box.”

The CTO Advisor group known as out the sturdy networking capabilities of Oracle Cloud Infrastructure (OCI), together with the power to dynamically scale knowledge middle connections up and down in capability. OCI permits a lot easier networking topologies each to connect with an exterior knowledge middle and to attach the VMware surroundings to different cloud providers supplied by OCI.

Safety highlights

The report additionally highlighted safety and compliance variations. Firms can prolong current compliance and certification necessities into the cloud with Oracle Cloud VMware Answer. They will do that as a result of their current operational processes stay according to the VMware environments within the cloud, and directors may also management the precise software program model and patch ranges of their VMware software program. Oracle’s method lets firms prolong their current governance to the cloud, after which change it at a charge managed by the corporate, not the cloud vendor.

With Oracle Cloud VMware Answer, entry to the VMware surroundings—together with the VMware software program, its knowledge, and the servers—is absolutely underneath administrator management. In contrast to different distributors, Oracle Cloud provides full management to the client after the automated provisioning steps, and not has entry to the surroundings.

Additionally contributing to safety is Oracle’s mixed providing of VMware software program and public cloud in a single account from a single vendor, which isn’t the case with all public clouds. This type of simplicity is an instance of how Oracle Cloud designs in safety from the beginning, from its elementary structure up by way of its built-in answer portfolio.


The final space examined by the CTO Advisor report is the general ease of use for groups which have current experience utilizing VMware options. Concerning the general expertise, the report says:
