IT managers and experts have praised VIO for combining the maturity of a VMware environment with the agility of OpenStack. Or you can verify their general user satisfaction rating, 100% for Apache CloudStack vs. 99% for OpenStack. The latter model aim at creating a cloud-like experience for workloads that have been engineered and developed in a more traditional “enterprise” way.” Cloud-aware applications will handle HA and DR policies on their own, while legacy application will rely on the infrastructure to provide HA and DR. See diagram below from an VMware cloud architect’s article. In OpenStack, there is no feature comparable to FT and there are no plans to introduce this feature. We suggest that you spend some time to study their differences and decide which one is … Some OpenStack services align with VMware's, but it's a short list. Stay on top of the latest news, analysis and expert advice from this year's re:Invent conference. I’ve given a couple of presentations to the SF Bay OpenStack Meetup on this topic and many peers have asked me to write about it. I agree with this point to an extent but as OpenStack matures so will the documentation. KVM live migration allows a guest operating system to move to another hypervisor . OpenStack vs VMware: Conclusions Due to the open-source nature of the OpenStack, the costs associated with its initial roll-out and ongoing operations are usually lower compared to VMware. To decide between using cloud infrastructure or virtualized infrastructure, first consider the infrastructure your organization already runs. All this though, comes at the cost of complexity, compatibility and stability. This makes for a fast transition time, since the data does not need to be copied/moved via a network. The downside is that it takes longer and requires CPU resources on both host and target to make the move. Why sink millions into “modernizing” an application to fit the Facebook design pattern when it is an application whose purpose ultimately requires 24×7 availability for a small (say 50,000), and static, population of users? I do hope people realize that N-tier architecture with ephemeral tiers and minimal persistent state (which is the basis for cloud design patterns), simply does not fit every use case. *As of vSphere 5.1, VMware supports live migration without shared storage. The design patterns discussion (the cattle vs pets thing) is accurate, but the reality is that many enterprise use cases simply don’t fit cloud design patterns. Presents the economic and efficiency benefits of taking an open-source approach. How does VMware VIO add cloud functionality to ... VMware Integrated OpenStack features, cost, benefits ...

Stay tuned! HA simply means that when something fails, it can be restored in reasonable amount of time via self healing. Before we can assign value to the features above we need to think about use cases. The software is thoroughly tested and has a monolithic architecture. Also, I think quantum has so much breadth that it may deserve its own post, so thanks for the idea. This course builds your skills in installing, configuring, and managing VMware Integrated OpenStack through a combination of lecture and hands-on labs. Whether our host software solution is for XIV, DS8000, Storwize, or any other IBM storage system – the release notes, user guide, or installation guide are available on the IC in either PDF or HTML format (whatever suits you best). All that being said, had you omitted scoring altogether, the article has a lot of very well-worded content regarding some of the differences in the two products. None of this is “cool and trendy” though, and “cool and trendy” is what tends to move tech blog traffic and certainly what is key when it comes to winning funding for startup projects. Some of the features offered by OpenStack are: Compute; Storage; Networking; On the other hand, VMware vSphere provides the following key features: Powerful Server Virtualization; Network Services Containers have represented a struggle for many vendors, including OpenStack and VMware. I completely agree that it will be difficult for enterprises to shift existing workloads to cloud aware applications. VMware FT livestreams the state of a virtual machine and all changes to a secondary ESX(i) server for protected VMs. Most importantly, it eliminates the requirement to have separate platforms for older, legacy applications that remain critical to an organization and for newer, more modern applications. Distributed Environment. However the datacentre is becoming more commoditised. However, you must understand how to incorporate cloud automation into your IT processes before attempting to introduce cloud bursting. OpenStack began as cloud technology, while VMware started as a virtualization suite for the data center. Finally, I think it’s important to remember that it’s not one against the other, as VMWare provides considerable support to the OpenStack project. Here we look at VMware vs OpenStack, and assess their keys strengths and weaknesses in storage. However, the answer to which provides the best value isn’t as clear, since it depends on scale. Fault tolerance means that when either the primary or secondary VM’s host dies, as long as the other stays up, the VM keeps running. VMware has associated costs for licensing but should be easier to install and get running. I’m also not going to argue that the scoring is subjective as I mentioned in the author’s notes. Virtual clusters enable admins to deploy, track and manage containers across various systems to ensure performance, security and ... Virtualized power systems promise to ease deployment and maintenance, but the market is still in its nascency. It’ important to compare these Vsphere features as they are what people seem to care about when moving from VMware to OpenStack. But that isn’t exactly the case. It protects you against a single host failure with no interruption to the protected VM. It makes sense for a service provider like RackSpace to build on it and sell it since they don’t have the resources to actually build a competitive public cloud platform on their own, but it just doesn’t make much sense for enterprise IT to adopt. Here’s an animal analogy for you – A free puppy isn’t free, and the bigger the dog gets, the less free it becomes. On other aspects missing.. I did a comparison with CloudStack, but without the scoring system here. OpenStack and VMware are in a battle, with both companies matching each other’s features. Good stuff here. Here you can also match their total scores: 9.8 for Apache CloudStack vs. 9.2 for OpenStack. This is good for OpenStack as VMware is extremely expensive and OpenStack is free. Otherwise the scoring system would have to be adjusted. The other big benefit is that because it’s open source, you can have more effect on the roadmap. During the live migration process the guest should not be affected by the operation, and the client can continue to perform operations while the migration is running. Although you can build a cloud computing environment off of a VMware vSphere infrastructure, OpenStack forms a cloud OS that can organize, provision and manage large resource pools. Once open cloud starts to really drive the management and cost down then it will win. Thanks for the reply, you make good points. Compares VMware’s proprietary virtualisation offerings with an open-source approach, Canonical’s Charmed OpenStack. In short, OpenStack has a higher initial cost, but as projects scale, you will get more value, due to the lack of licensing fees. Since their is no benchmark for the engineering staff mastery of design and features in particular application, it lands up costly and risky in end. Analysis of Docker Enterprise Container Cloud, Why, When and How to Upgrade to Docker Enterprise Container Cloud. No problem! Would have been nice to have compared Quantum with VMware’s Networking capabilities as well. Nice coverage, but I would like to have read about a comparison of more features than just Fault Tolerance and High Availability. Massimo Re Ferrev Cloud Architect at VMware. Companies are not paying for hypervisors they are paying for the ability to manage the infrastructure. Use the right tool for the right job until you find a better tool. Since they belong to two different generations of architecture, a direct comparison of OpenStack and VMware is difficult. This section describes how to configure VMware-based virtual machine images for launch. VMware's role in OpenStack: A second look. Cloud War or Data-center war ? Start my free, unlimited access. Some aspects I will consider are open vs. closed systems, Enterprise legacy application vs. cloud-aware application, free vs. licensed, and well-tested features vs. controlling your own roadmap. With so many companies devoting resources to OpenStack it has no dependencies to a single company. As the VMware vs. OpenStack debate rages on, the community around the open source platform won't give up. I will make the adjustments now. http://www.serverwatch.com/server-trends/paypal-picks-openstack-at-vmwares-expense.html. Or a mode where you can ignore DRS load balancing during specific set hours. However, the deployment and architecture have a steeper learning curve than VMware and the documentation is not always current. They don’t directly monetize technology, but rather use technology to facilitate business value. I think it will be interesting to see if it’s too late for Openstack to claim a slice of the vPie. When the load grows, DPM turn hosts on again and spawns VMs on them. In OpenStack, shared storage is not required for VM migration since there is support for KVM block migration. As VMware increases their lead in the features category, they have invested a great deal in features like vMotion, HA, FT, and other ways to protect the VMs. As I mentioned these are the most asked for features when I work with clients thinking of switching to OpenStack. There are a couple ways to connect the disparate pieces of a multi-cloud architecture. It has utilities that can automate patching and upgrading, and it offers critical VMware products, including vSphere, NSX and VSAN, through OpenStack APIs. As a simple example.. just because CPU is high during backups in the middle of the night for a short window.. doesn’t mean you should move the VM off to another host .. Another example.. . When they get ill, you nurse them back to health. Here is a direct quote from VMware vcloud Architect that claims VMware solutions is better suited for Legacy applications, while AWS and OS model will better suit cloud-aware application. Furthermore, you will pay license fees for features you may not need and have no control over VMware adding the features you do need. DRS continuously monitors the active workload and the available resources and performs VM migrations to maximize workload performance. You can gain access to VIO with a vSphere Enterprise Plus license, but it doesn't include support. Consider your organization's priorities and resource allocation when you think about the storage requirements of vSphere vs. OpenStack. how we can get Storage vMotion/sDRS works in a openstack environment while the underlying resource pool still consist of a VMWare environment. With a maturing core, improved deployment and scaling capabilities , as well as a growing ecosystem of services, OpenStack is more usable in the enterprise today than in the past. However, VIO features can be expensive. The table below gives, at a … This results in the limitation that only single vCPU VMs can be protected with FT. There is no discussion of the ISV support (key ISV’s only providing ‘support’ for applications running on VMware) issue nor the very top of mind issue of migrating Applications to from Pets to Cattle. It encompasses VMware's server virtualization product suite, including its ESXi hypervisor, vCenter Server, an HTML5-based management interface and other popular virtualization components. More differences: Cloud resources are agnostic and disposable, while virtualization demands the care, feeding and nurturing of virtual machines. Vcloud Director used to manage multiple VMware data centers, but it can only work with vSphere, hence why it’s important to compare the features at the vSphere layer. VIO support is purchased on a per-CPU basis. DPM leverages vMotion by moving VMs off hosts and shutting them down during periods of lower load to reduce power consumption. This pile of legacy, and often cumbersome, process around delivery to ensure security and compliance is at the core of the business. Licensing is a small cost compared to the massive burden of operational and integration complexity. But instead, have a global layer based on OpenStack… but is still capable to manage and provision to underlying resources which uses one or more hypervisor technologies (Hyper-V, KVM, VWWare, Public Cloud, etc). Since “value” is not only dollars but usefulness per dollar, in my experience the simpler and more automated is of higher value. This is an excellent detailed dive into the differences. Thanks for your comment. Submit your e-mail address below. Completely unrelated to that point: I’d like to see you keep this going and talk about security in both environments. LEARN MORE. Cloud design patterns originally emerged from the huge public players because of this need for infinite scale. A similar head to head with CloudStack would be interesting. Lee : you should be comparing the trifecta of: vSphere – the hypervisor, vCloud director – multi-tenancy via vIrtual DCs ie for separate business units (not only multiple physical data centers)and vCloud Automation Center which is a governance portal which sits on top of vCD to determine who has access to what resources and where will the resources live. Thanks for the feedback. I think there is some confusion. And as I understand OpenStack, it actually supports vSphere as a hypervisor. The VMware driver supports vCenter version 5.5.0 and later. . This is especially true if the main purpose of moving VMs is host maintenance. Future application architectures should use cattle. DRS leverages vMotion by dynamically monitoring the resource usage of VMs and hosts during runtime and moving the VMs to efficiently load balance across hosts. If you know a spike is going to happen in the future, it would be good to feed DRS with input from the future. Which is why I’m always ranting about being sure that the features we implement — especially around PaaS and orchestration — complement and reinforce the Cattle viewpoint. 8. 1) Yes, i agree that the initial cost of set up for OpenStack can be high, so in smaller scale use cases, it makes sense to use VmWare. And in cases where an architectural shift *could* work, there is a ton of cost in attempting it and limited value in shifting it “just because”. With regard to increasing supply of talent, look at how much linux talent is now available compared to when linux started gaining momentum in the server space, this is purely a function of demand. In conclusion, this is biased marketing that serves no useful purpose – subjective (highly) as you have stated. While OpenStack is free to use, it does require a lot of engineering resources and expertise. Both can be augmented to support the approaches but there are different use cases for when one fits better. Source of cost might be purchase price, complexity, stability risk, or lifecycle costs. and probably don’t want to convert everything they have into OpenStack. VMware’s suite of applications was built from ground up, starting with the hypervisor. When VMware purchased Nicira, I expect that most of the features Nicira developed for quantum(OpenStack) will be going in to vDS (VMware) as well. You kind of alluded to this above – is that the case? Interestingly, Best splits out benefits and costs. Thanks for the comment. For instance, when managing load on hosts, DRS might seem unnecessary on a couple hosts with 50 VMs, but it proves essential when you’re managing hundreds of hosts with tens of thousands of VMs. Some might *never* fit because they just don’t line up. Furthermore, instructions mirroring is not supported by KVM (the most common hypervisor for OpenStack). That said, I think this evaluation would be better with a few key adds.. separate from the aforementioned ‘more VMware’ features. The OSS community always misses this reality when trying to understand why enterprises dont just “stop paying for software and services and build everything out of “free” bricks”. Some of the largest deployments choose OpenStack because of its support for both VM and bare metal compute types, including both legacy (monolithic) apps and cloud-native environments with containers orchestrated by Kubernetes. To make it interesting, I’ve decided to structure this as a head-to-head bout between these two cloud software contenders competing for usage in your data center. The scheduler is quite flexible and can support a wealth of filters, but consumers can also write a custom filter using JSON. In a previous draft, I had credited Microsoft, but switched it because I never found an online reference. VMware Bests Red Hat In OpenStack Performance, Cost Study While the operating assumption is that the OpenStack framework works best on open source components such as KVM, a just completed study by Principled Technologies and commissioned by VMware showed otherwise. Accelerate Digital Transformation with Converged Infrastructure. However, I do encourage to feedback as to why you disagree with the verdict. It requires twice the memory as memory cannot dedupe via TPS across hosts. The data used by the scheduler to determine which host to provision to is the static data derived from the nova database. When it comes to OpenStack vs VMware, a lot of misinformation is floating around the web. It reminds me of a marketing assessment I saw last year: http://rogerjbest.com/nav.cfm?A=N&C=6&P=1. A 64-bit guest can only be migrated to a 64-bit host, but a 32-bit guest can be migrated to either. I know the scoring is there to add another interesting dimension – and it works. Without Vsphere, ESX(i) is simplified to just provisioning VMs and snapshotting. Also, VMware has training programs and certifications. The biggest cost in the DC are power and cooling this drove the move to virtualisation. Vmware and openstack is never end process and always been shine in IT Marketing field.I Agreed with your information.New features will added to openstack in future based on client requirements. The former model aim at creating a brand new experience in how applications are engineered, developed and operated. So in your use cases benefits category, they would probably score about the same (for cloud workloads), but VMware would score much, much worse in terms of price costs – although it would be interesting to assess other costs as well. Enterprises don’t run infinite scale like Netflix, Facebook, Google, Amazon and Twitter. If you already use VMware, consider extending a VMware facility to support cloud bursting, which creates business continuity and protects your VMware investment while also enabling you to take advantage of the cloud. Enter a name for the VMware Integrated OpenStack vApp, select the data center that you defined during preparation, and click Next. I’d argue with a few tweaks, OpenStack could be better at handling the Pets paradigm as well. The ESX(i) hypervisor is free and provides an excellent support structure for VMware orchestration products such as vSphere and vCloud director. In a title bout between two of the biggest players in the cloud landscape, VMware took a big lead early on in features and design, but OpenStack came through as the underdog and won the competition by dealing a knockout blow in value. We compared these products and thousands more to help professionals like you find the perfect solution for your business. While OS seems to avoid VMware licensing costs it also seems to introduce (potentially) the highest cost of any IT shop: people/labor required to run it. Vmware wins the battle in the management arena. OpenStack sandboxes are common and easy to deploy; however, OpenStack has struggled with managing scale, user friendliness and feature completeness.
