. Truth be told, the scoring is not perfect and completely subjective, since the reason for its existence was to make the material a little more interesting. These include Docker Enterprise Container Cloud (now Mirantis Container Cloud), Docker Enterprise/UCP (now Mirantis Kubernetes Engine), Docker Engine - Enterprise (now Mirantis Container Runtime), and Docker Trusted Registry (now Mirantis Secure Registry). All this though, comes at the cost of complexity, compatibility and stability. In the vSphere vs. OpenStack debate, choosing the right infrastructure for your organization's data center comes down to your staff's expertise, your existing infrastructure requirements, your storage setup and whether you can compromise with vSphere Integrated OpenStack. . Thanks for this detailed reply. The former model aim at creating a brand new experience in how applications are engineered, developed and operated. In conclusion, this is biased marketing that serves no useful purpose – subjective (highly) as you have stated. VMware's role in OpenStack: A second look. That said, I think this evaluation would be better with a few key adds.. separate from the aforementioned ‘more VMware’ features. “The AWS / OpenStack model can be seen as a forward leaning model whereas vCloud Director can be seen as a backward leaning model. Provides a detailed cost analysis highlighting the savings an organisation can make by migrating from VMware to Charmed OpenStack. However, the deployment and architecture have a steeper learning curve than VMware and the documentation is not always current. vROPs) …. Its had a large head start. As I mentioned these are the most asked for features when I work with clients thinking of switching to OpenStack. In the cloud ecosystem there are two types of tenants that consume infrastructure as a service: cloud-aware and legacy. Here’s an animal analogy for you – A free puppy isn’t free, and the bigger the dog gets, the less free it becomes. IT lags in maturity and capabilities and has a hard time just keeping the lights on in most cases. There are a couple ways to connect the disparate pieces of a multi-cloud architecture. The other big benefit is that because it’s open source, you can have more effect on the roadmap. The reverse is true with vSphere. IT managers and experts have praised VIO for combining the maturity of a VMware environment with the agility of OpenStack. Please note: Mirantis has realigned its portfolio and renamed several products. Once upon a time , mainframe was ruling in the market . The data used by the scheduler to determine which host to provision to is the static data derived from the nova database. The top reviewer of Rackspace OpenStack writes "Highly customizable private cloud solution". Stay tuned! This hasn’t happened in the past with complex domains which is precisely why CIOs want to get *out of the business* of running super complex stuff that requires expensive talent. VSphere is the predominant virtualization software. OpenStack is a collection of open source software, providing a cloud framework that enables you to create and manage both public and private cloud infrastructures. When it comes to OpenStack vs VMware, a lot of misinformation is floating around the web. Interestingly, Best splits out benefits and costs. Cloud War or Data-center war ? Containers have represented a struggle for many vendors, including OpenStack and VMware. In fact, it’s one of the most popular topics among those thinking about using OpenStack. Lack of easy-to-use, documentation finally shifts the problem from upfront low-cost to engineering staff expenses maintaining the product. Furthermore, you will pay license fees for features you may not need and have no control over VMware adding the features you do need. LEARN MORE. This results in the limitation that only single vCPU VMs can be protected with FT. There are use cases when block migration is a better option than the classic live migration because the ability to use only the network to migrate your VMs can be priceless. VIO support is purchased on a per-CPU basis. I could compare OpenStack with ESX(i) to Vsphere with ESX(i) – but the majority OpenStack features are being developed with KVM. VMware vCloud installation is a set of components that need to be downloaded, installed and configured separately. I’d argue with a few tweaks, OpenStack could be better at handling the Pets paradigm as well. While OpenStack is free to use, it does require a lot of engineering resources and expertise. The scheduler is quite flexible and can support a wealth of filters, but consumers can also write a custom filter using JSON. Thanks for the correction and reminder. In this case, a block migrate is the ideal solution. Have you considered giving the two solutions a re-match to see how they stack up today? Do Not Sell My Personal Info, I would encourage anyone interested in OpenStack to check out. Here you can also match their total scores: 9.8 for Apache CloudStack vs. 9.2 for OpenStack. Enterprises bring forward a ton of legacy and monolithic application stove pipes. OpenStack belongs to "Open Source Cloud" category of the tech stack, while VMware vSphere can be primarily classified under "Virtualization Platform". I think it will be interesting to see if it’s too late for Openstack to claim a slice of the vPie. 7. Private Cloud Debate – Openstack vs VMware. Still, you must weigh the cost difference of paying for a monthly cloud subscription versus an upfront fixed-cost purchase of hardware. 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. VMware was late to introduce cloud products compared to other vendors -- specifically, OpenStack, its competitor in private cloud deployments. I’d have to agree with Qflux.Open stack is still relativley immature. Distributed Environment. – The OS Scheduler could kick DRS to the curb over time because of this latter difference, especially if it became extensible/modular/’have the provider model’. Also, I think quantum has so much breadth that it may deserve its own post, so thanks for the idea. Currently, there is no official support for VM-level HA in OpenStack—it was initially planned for the Folsom release but was later dropped/postponed. 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. 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. Fair point. That being said, cloud use cases are trending toward large scale and as people get more experience with OpenStack, the initial costs will be lower. While the scheduler is flexible, and highly customizable, it’s not quite a replacement for DRS for the following reasons: VM-level high availability (HA) in vSphere allows for the spawning of the same VM to a different host when the VM or ESX(i) host fails. 2. When I’m comparing the features above I’mm comparing OpenStack with KVM to Vsphere with ESX(i). As someone who has used VMware for many The ESX(i) hypervisor is free and provides an excellent support structure for VMware orchestration products such as vSphere and vCloud director. Supports a wide variety of persistent storage endpoints such as NFS, GlusterFS, OpenStack Cinder, FlexVolume, VMware vSphere etc. There is currently an incubation project called Evacuate that is adding support for VM-level HA to OpenStack. OpenStack is no slouch here, though, since it was designed from the ground up for flexibility and it’s vendor agnostic in terms of hardware and hypervisors. Presents the economic and efficiency benefits of taking an open-source approach. 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. 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. The Pets vs. Cattle analogy originally came from William Baker at Microsoft: http://mem-pass.org/summits/2011/pdfs/DBA-302-HD.pdf. OpenStack uses a scheduler to select an appropriate host for your VM based on a list of attributes and filters set by the cloud admin. Licensing is a small cost compared to the massive burden of operational and integration complexity. I believe that OpenStack could certainly be better at handling the Pets paradigm, but I hope that the development of features isn’t just about a “VMWare has this capability, so we should have the same” decision, as too often features developed in that way tend to mimick APIs and interfaces that reinforce the wrong/outdated/monolithic design principles that led to the Pets thinking in the first place. It requires twice the memory as memory cannot dedupe via TPS across hosts. VMware vSphere. The latter model aim at creating a cloud-like experience for workloads that have been engineered and developed in a more traditional “enterprise” way.” This pile of legacy, and often cumbersome, process around delivery to ensure security and compliance is at the core of the business. Many have implemented VMware Integrated OpenStack (VIO) to get the best of both vSphere and OpenStack. This was a fantastic article 3 years ago. Analysis of Docker Enterprise Container Cloud, Why, When and How to Upgrade to Docker Enterprise Container Cloud. 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. True application-level clustering like MSCS or WCS are required to protect against application-level failures. 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. Please check the box if you want to proceed. Would have been nice to have compared Quantum with VMware’s Networking capabilities as well. OpenStack catches up in this category, since many of the features VMware had (and OpenStack didn’t) are not necessarily useful for cloud-aware applications. HA simply means that when something fails, it can be restored in reasonable amount of time via self healing. 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. “Opinionated” storage solution through integration with vSphere via Project Pacific; Self-Service Provisioning. I really love the idea of Openstack, and I hope it gets the backing it needs to morph into an enterprise quality, dependable solution. 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. 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). Submit your e-mail address below. It reminds me of a marketing assessment I saw last year: http://rogerjbest.com/nav.cfm?A=N&C=6&P=1. vMotion is the building block for three vSphere Features: DRS, DPM, and host maintenance. 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. Why should one disagree with the verdict? The scoring method was a useful mechanism for describing your perspective on the relative value of each solution. To decide between using cloud infrastructure or virtualized infrastructure, first consider the infrastructure your organization already runs. Thanks for the reply, you make good points. Since the storage is shared, the data does not need to move at all—rather the link to the data changes from one host to another. You can gain access to VIO with a vSphere Enterprise Plus license, but it doesn't include support. Some deployments do not have shared storage but still need to perform maintenance on compute nodes like kernel or security upgrades and VM downtime is not acceptable. On DRS vs. the OS Scheduler We can definitely have follow up blog on both security features and the vCloud Director features and another blog. VMware vSphere and open source project OpenStack present two different ways of structuring an infrastructure. Rackspace OpenStack is rated 8.0, while VMware vSAN is rated 8.4. 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). The main dependency here is shared storage, which can be expensive. You can migrate a guest back and forth between an AMD host and an Intel host. OpenStack began as cloud technology, while VMware started as a virtualization suite for the data center. I’m sure when the day comes where all VMs become cattle then Open Stack and it’s teams of Virtual Farmers will be happy as pigs in a Data Center. Copyright 2007 - 2020, TechTarget I think there is some confusion. 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. 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”. I’m sorry you found the information useless, if you can point me to a more useful comparison I’d appreciate it. If we talk about the comparison between VMware cloud and OpenStack, vCloud is way behind OpenStack as OpenStack has a huge scope of features displayed. Accelerate Digital Transformation with Converged Infrastructure. VMware Integrated OpenStack greatly simplifies deploying an OpenStack cloud infrastructure by streamlining the integration process. This is especially true if the main purpose of moving VMs is host maintenance. 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. KVM live migration allows a guest operating system to move to another hypervisor . years and caring for many ‘pets’, I couldn’t agree more with QFlux. All excellent points, Toby. Some might *never* fit because they just don’t line up. I really don’t see how the complexity of OpenStack makes sense for IT organizations looking to simplify, control costs, and start to return more business value more quickly to their enterprise. Only on blogs and comment streams is everything determined by a technical scorecard. The categories will be scored on a 10-point scale and then tallied to determine the winner. The open infrastructure community is welcoming and happy to answer your questions. Besides KVM, there are many deployments that run other hypervisors such as LXC, VMware, Xen, and Hyper-V. Common characteristics of cloud-aware applications: Common characteristics of legacy applications: Here comes the final round that decides it all. Regarding the pure marketing remark, I covered the features with quite a lot of technical depth which actually sparked additional discussion about the technology as you can see from the other comments. I’m not sure how this reply is related to my post. 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. *As of vSphere 5.1, VMware supports live migration without shared storage. Openstack es la plataforma de Cloud Computing de Código Libre más importante. Couple of thoughts from the peanut gallery: 1. It protects you against a single host failure with no interruption to the protected VM. You won’t have a whole lot of difficulty finding a VMware professional if you need one in a bind. I would disagree with the idea that larger scale provides higher value for OpenStack. Considering other FT limitations, like high resource usage, double, ram, disk, and cpu, and bandwidth to livestream the state this is one of the less used VMware features. Despite VMware recently rebranding the ESX(i) name as “Vsphere Hypervisor”, Vsphere is definitely not just a hypervisor. and probably don’t want to convert everything they have into OpenStack. Typically a monolithic chunk of code; hard to scale horizontally. As the VMware vs. OpenStack debate rages on, the community around the open source platform won't give up. As I stated previously, the score card is just to make the read a little more interesting. In OpenStack, shared storage is not required for VM migration since there is support for KVM block migration. Here we look at VMware vs OpenStack, and assess their keys strengths and weaknesses in storage. And as I understand OpenStack, it actually supports vSphere as a hypervisor. Enter a name for the VMware Integrated OpenStack vApp, select the data center that you defined during preparation, and click Next. I need to start to use the Pets vs. Cattle analogy.. That’s a good one.
