The path to the downward evolution of virtualization applications

Virtualization and its cousin Cloud computing have become an important trend in this field, according to today's computer-development bandwagon. Today, although the slogan is easily publicized, there is no good understanding of the meaning of virtualization and how virtualization can change people's lives. This is true, in part because virtualization has many forms, and cloud computing seems elusive. But anyway, we've all tasted the benefits of virtualization and cloud computing. When you use Web mail, search on the internet, and visit websites, these are the technologies that are implementing functionality. At first the virtualization technology was designed for mainframe computers and computer arrays, and now it's starting to come into our homes and businesses.

Virtualization applications continue to evolve down

In a word, virtualization is abstraction. Virtualization is the first to be applied to large computer platforms. Mainframe computers need to avoid a crashed application impacting other applications. In the 80 and 90, many mainframe computers were configured with more than 10 individual servers and networks, resulting in the de facto isolation of "one application, one server" fashion slogan. However, this trend has shifted as PC and server processing can rapidly increase and prices fall rapidly. Systems that are configured with dual-core or quad-core processors, gigabytes of memory, or terabytes of storage capacity replace many older servers.

VMware virtualization programs and Microsoft's Hyper-V virtualization programs use a software program called a hypervisor to create a small layer between the computer hardware and the operating system and the application. Earlier versions of the virtualization program impacted the performance of the system, but the latest generation of virtualization programs made this layer transparent. This separation effort provides isolation, but another benefit of it is standardization. For each virtual environment, the hardware of the system seems to be the same, enabling not only the virtual machines to coexist, but also the ability to replicate and migrate between systems, creating testing, flexibility, and redundancy. Although virtualization was first used in data centers, it is playing an increasingly important role in desktop and notebook computers. In these environments, virtualization technology enables Mac and Linux laptop users to keep XP and Windows applications while running their new applications.

Another trend is that faster, more reliable and more pervasive internet access makes internet-based hosted services (or cloud computing) a reality. An internet-connected "large channel" enables applications to migrate from a local desktop computer or server to a data center in the cloud. Starting with Web sites and hosted emails, cloud computing has quickly increased services such as E-commerce, CRM systems, disaster recovery backups, and even video-on-demand. Once the Internet connection is fast and reliable enough, our desktops and laptops become just windows for virtual storage and application libraries. This will be the advantage of small business customers taking advantage of economies of scale and the energy-saving cost of sharing resources. You can also access these resources from home, at the workplace, or wherever there is an Internet connection. Why do you spend thousands of of dollars on expensive apps that are rarely used when you can share them?

Leveraging cloud computing to keep a close eye on small and medium enterprises

Doyenz.com's new generation of virtualization and monitoring tools, presented at a recent meeting of the WSTA (West Sound Technology Association), brought this functionality to SME users. Most small businesses have only one server and are not capable of backup. So when the server fails, everything stops. Doyenz is a technology company whose main task is to improve the quality and efficiency of it technology provided to SMEs. Its virtualized IT products are a managed service for small value-added service resellers and IT consultants managing 30 to 50 customers. This service only pays a small monthly service charge, has no long-term contract and does not require the purchase of hardware and software. These services can leverage virtualization, automation, and cloud computing services to provide a high level of service. Customers will pay less for IT services because they are more efficient and have built disaster recovery capabilities in the process.

These patented virtualization tools enable small businesses to retain virtual replicas of their servers in cloud computing data centers or in local networked storage, using different compression and contrast technologies to reduce transmission time. This virtual test lab allows new application patches to be tested on virtual servers running in a production environment. If an error occurs, you can easily perform a return order. A remote monitoring and management Service can keep the server running with minimal intervention.

Finally, this "contactless service" backs up a virtual server on your local network and backs it up to a comprehensive disaster recovery solution. If a server breaks down, the latest virtual backup can be routed to a desktop system as a temporary replacement, allowing the running business to continue running with minimal downtime. Doyenz is also working with partners to provide a solution that allows users to permanently run their servers in cloud computing, or to start saving a copy of the server in a fault-tolerant mode in cloud computing, preventing a catastrophic failure on the site's servers. In the near future, there will be migration services for server and application software in cloud computing.

As virtualization and cloud computing come together with faster Internet connections, the way we operate computers and other media systems in our homes and businesses will change dramatically. For example, with the introduction of effective video and music on-demand services, no one doubts the importance of CDs or DVD libraries. This phase will separate your digital world, separating the digital content you use at home and in your business from the hardware devices you use.
