    The Meaning and Workings of Virtualisation

    When IBM launched the CP-40 in 1967, it changed the whole dynamics of computing. Though the concept of virtualisation was ringing the bells from a year before, 1967 was the time which is credited for being the cradle of virtualisation. The CP-40 was based on complete virtualisation and could run 14 system simultaneously. Fast forward to the early 2000s, VMware took virtualisation on a different level, allowing it’s user to work on a different operating system through a virtual machine. The business of today cannot ignore the power of virtualisation if they have to stay relevant.

    What is Virtualisation?

    Virtualisation refers to creating a virtual version of a resource. It simulates a virtual environment of a computing resource such as a server, operating system, desktop and network. Often, many virtual resources can be created from a single physical resource. It allows better efficiency and utilization of resources giving greater revenue for business with economies of scale. A virtual computer or VM works in an isolated environment with its own dedicated resources such as RAM, storage and OS. The bridge between the physical host and the VMs are controlled through a software called the hypervisor. Through hypervisor, a physical resource is partitioned into many VMs.

    Components of Virtualisation:

    There are basically three components of a virtualised environment:

    1. Host machine– This machine forms the basis of virtualisation. The physical hardware that allows virtual machines to exist by allowing hypervisors to be installed on them. The primary purpose of the host machine is to provide the basic physical infrastructure to the VMs.
    2. The guest machines– The virtual machine which is created in simulation on top of the host machine is known as the guest machine. One single host machine can run many VMs. Each VMs run separately without any interference from

    What Factors Will Shape Information Technology Careers in the Next 5 Years?

    As economic and social factors always shape the IT industry, we look at four compelling pressure points that may have the possibility to significantly affect IT careers within the next 5yrs.

    #1 Society

    As society’s dependency on IT systems is maintaining growth, the strain around the professionals who dream up, design and support scalping strategies become more and more stringent. Computers aren’t just the domain of engineering minds, children to grandmothers will also be on board and everyone else between. This makes the Internet more essential to the society of computer has ever been.

    #2 Cloud Computing

    Cloud computing will be the presentation of an alternative party service into your network. This is another concept that’s gaining momentum primarily due to recent advances in telecommunications, processing and storage capacity. This service model has the opportunity to rock technical roles from the IT workforce. Although it could be more accurate to say until this model (if successful) could be the catalyst as opposed to the cause of the change in workforce skills demands.

    #3 Internet Addresses

    The current Internet address space referred to as IP version 4 is 95% depleted. Its successor is referred to as IP version 6. Interestingly, the (eventual) implementation of IP version 6 features a huge potential to shape IT career profiles. Ironically, the possibility of this new protocol may be the same potential dreaded by some large corporations these days. You see this protocol gives residential users to be able to participate in the Internet by serving information, rather than just receiving it. It can be said this functionality resembles today’s’ peer-to-peer protocols on steroids!

    It can be possible that the IP version 6’s ‘next killer application’ will be one which harnesses this functionality to empower home users in a manner that’s today very difficult to …

    The Guide to Choosing the Best Cloud Hosting for Your Website

    When it comes to cost-benefit analysis, the performance of a Cloud Web Host is unmatched. The reliability and scalability features of Cloud Hosting make it the most advanced type of web hosting available in the market. However, simply choosing a Cloud Web Host may not do much good for your website as a number of factors depend on the plan and the hosting provider. Therefore, it becomes important to sort out a few things before selecting the best Cloud Hosting solution for your website.

    Things to keep in mind while selecting a Cloud Hosting

    1. Understanding your needs: No two websites have the same requirements. Thus, it is essential to chalk out all your needs and requirements before taking the plunge on selecting a provider. Many providers give a trial period by which you can evaluate the benefits and performance of the provider.
    2. Hardware and software: The backend infrastructure and hardware configuration are what makes a Cloud Hosting an effective solution for your website. It is important to understand various parameters which determine the performance of the cloud. Applying caching techniques such as Varnish caching can effectively boost the performance of your website by multiple times. Also, the performance of the cloud relies on the type of storage used. Storage architectures like Ceph storage comes with many advanced features such as self-healing which can give a major boost to your cloud-based website.
    3. Load balance: Load balancing is utilized in Cloud Hosting to make sure the website doesn’t experience downtime when one of the servers is malfunctioning. This server backup plan is crucial to redirect to the active server to avoid downtime. This is an important aspect which you must consider before choosing a hosting provider.

    Duties of Change Managers Described During ITIL Training

    The core of the change manager’s job in ITIL-based systems is to create protocols to handle changes in system configuration directly and in use. Changes can be subject to external manifestations as problems in the system. In that case, change management is a reactive process. Changes can also be implemented in an effort to improve system performance. In that case, change management is considered a proactive process.

    In each event, this type of change can involve a new system strategy, an increase in a specific area in the system, a change in technology or a change in service perspective.

    The New Strategy Seeks To Reset The System’s Focus

    A typical example is the globalization of information systems where local area networks must be equipped with internet connectivity, a feature that will require more control to be incorporated into the system. Another example of this is enabling online bill payments. In both examples, the change manager must authorize and control the rate and manner in which remodeling of the system must occur so as not to push it out of balance. In other words, change management sets the standard process that must be taken if the need for change is felt so as not to interfere with the normal operation of the system.

    Need To Be Upgraded Or Adjusted

    Sometimes, one or more modules in a system need to be upgraded or adjusted to produce better output. After this need is identified by the configuration manager, it channels requests for changes to the change manager who then studies the implications of the revision to the current system stability. On the basis of his findings, he can recommend procedures for implementing those changes, can modify the changes or reject them altogether.
