Domestic free virtualization OVM vs. OpenStack

Domestic free virtualization OVM Compared with OpenStack, OpenStack as a global open source software, its design was first positioned for large and medium-sized enterprises, because these enterprises can send a rich and powerful technical team for in-depth development and maintenance, and For lack of software development and operation and maintenance capabilities of traditional enterprises and SMEs, Yi Siwei OVM is 100% better choice.

OVM is a one-stop solution out of the box

OpenStack open source software installation and deployment for many operation and maintenance personnel are no stranger to, most enterprises only provide installation packages and simple installation documentation, and most of these installation processes will involve the database, redis, rabbitmq, ruby ​​and other environment configuration, these The configuration also requires operation and maintenance personnel to learn the installation and deployment of the above software, otherwise the one-step configuration error will cause the overall installation and deployment failure, resulting in the entire installation and deployment of as little as 2-3 days 1-2 weeks to complete the dilemma, complex Installation and deployment process for the operation and maintenance staff exhausted. Openstack as an open source product is no exception, and OpenStack downloadable manufacturers have more than 20 customized versions, customers simply do not know which version should be selected, not to mention combinations between different vendor versions, mashups, migrations, for IT investment Smaller and less skilled SMEs can only feel frustrated.

OVM is a free server virtualization software out of the box for the data center. Compared with the traditional open source software, the OVM installation and deployment (including the management platform and the compute node) adopt a one-button ISO method and the entire installation The process is as simple as installing a CentOS operating system and takes only 10-20 minutes to complete. Even the operation and maintenance of white, through the OVM ISO image can also be completed within 1 hour to complete the installation and deployment of products.

The stability of OVM can stand the test

OVM from the beginning of the architecture design fully take into account the stability of the product, and put stability in the first place. Because it is a piece of Iaas-class virtualization management software, it is more than just a piece of software, it's a hub that connects users to data centers (including physical machines, storage, networking, firewalls, disaster recovery, etc.). In architectural design, OVM also has the advantages of open source software and commercial software. First, it ensures that the product has no single point of failure, that is, the management platform is highly available. Secondly, it supports distributed deployment and minimizes the loss caused by unpredictable factors. OVM architecture, including distributed and plug-in, these two features allows users to deploy different modules and services on the same Server above, or can be deployed separately on multiple servers, greatly improving the deployment flexibility, It also minimizes the risk of single points of failure. In addition OVM introduced Zookeeper, Pacemaker and other software to provide high availability OVM, to avoid single point of failure. Each version of OVM undergoes rigorous closed beta testing and is officially released to the public. Every aspect of the OVM is strict quality control, and stability runs through every aspect of the OVM product.

OpenStack upgrade every six months, each upgrade requires a lot of time to fix bugs. According to a user survey on OpenStack done by www.51cto.com, 33.33% of users think OpenStack is not yet stable enough and can be difficult to modify.

OVM upgrade easier and easier

For a product, the iterative upgrade is an inevitable thing, the future product development planning, OVM will consider how to make users effortlessly upgrade can use the latest version. Ultimately seamless integration with the UI, users simply click on the WEB management platform, a button upgrade button can easily achieve the rapid version upgrades, and will not affect the normal operation of the business.

OpenStack Nova, Swift, Cinder and Neutron use their respective database storage configuration information,

To upgrade it is necessary to modify multiple database schema, can not do thermal upgrade. Another example is HP's Platinum members of OpenStack encountered a nightmarish experience when deploying Network Services (Neutron) and had to rewrite the code for network components to meet the requirements of large-scale applications. Another problem with OpenStack is that six months of rapid iteration, the release of new products, too fast, the old version can not keep up, in theory, the new version backward compatible, but when some major changes, adding new features, if the company has depth With the older version applied, there may be issues that the technology can not be upgraded with or require heavy development. This shows that OpenStack in the integration, scalability and practicality is not enough, if you want to choose, you need a team of experts to help implement.

OVM can provide end-to-end service

As the sole service provider of OVM products, Easyysoft OVM community provides unified product functions and technical services, provides user-oriented product functions, and provides users with end-to-end service assurance.

OpenStack does not provide end-to-end service assurance. Automated deployment, automated operation and maintenance, condition monitoring, device management, availability detection, security, reliability, and platform self-healing capabilities for the cloud platform are either missing in OpenStack or are scattered in separate products. Customers get the hands of just scattered "skeleton" must be manually by professional and technical personnel multi-vendor, multi-version of the integration function by function, which is obviously very difficult for small and medium enterprises.

OVM has better architecture and performance

In contrast to the unwieldy architecture of OpenStack, the OVM is more lightweight and simpler for early and later operation of the product. As we all know, OpenStack size modules and components will add up to dozens, in order to really understand each component, one or two people can not be completed, it must have a strong technical team to support it. And direct use of open source OpenStack there will be many bugs, not large-scale commercial, so many companies can only choose commercial company package OpenStack version. Also important to note is that OpenStack is not a product, only architecture, all versions developed in the open source community, only "encapsulated" before they can be used. General business does not have this technical strength, IT companies need to help implement, operation and maintenance, development and other work, this undoubtedly adds to the overall cost of the enterprise.
