The IT infrastructure virtualization is one of the most commonly used technologies and a crucial element of IT solutions for companies of any size. It enables the optimization of the used resources and starting-up multiple virtual machines on one physical server. Virtualization is used for cluster creation which are devices made of a few physical servers and shared bulk memory. They are designed in a way that the failure of one element of a cluster does not influence the work continuity of virtual machines working on it. An additional advantage of cluster systems is the possibility of quick additional logical server creation within the used infrastructure practically for free. Newly created machines can be a copy of the already used systems and they can serve as a testing ground during updates or software changes.
Servers and virtual system administration
From the perspective of an operating system it does not matter if it is running on a physical server or on a virtualized machine. There are some nuances when it comes to the virtualization devices and the device resources of a service-hosting server. Not all of those resources are directly accessible for an operating system of a hosted machine, i.e. USB ports. On the other hand, cutting a virtualized machine from specific server components is a desired feature from the point of view of the virtualized machine migration between the cluster nodes. The systems are designed in a way that they are independent of certain equipment resources using the adequate network converters. The virtualized machine operating system administration itself operates in a similar way to a system based on the physical server.
Protection clusters that are resistant to failure by providing the redundancy of certain elements are becoming more and more popular solutions even in smaller companies. Thanks to using the vSAN technology you can forgo buying relatively expensive disk arrays and use servers as the hosts of the hyper-convergence infrastructure solutions that include among others data collection space directly on the server resources.
Using the cluster does not limit itself to only booting the Linux or Windows servers. More and more often the equipment providers offer their solutions only as the cluster installation software without the need to buy a physical device. This solution is cheaper to install and maintain than buying the device because we do not additionally need to pay for the hardware and the high-level functionality is included in the price and comes from the operational role of the cluster and virtualization. The administration and backup preparation is also easier. Among the most common solutions provided by the software and not hardware is WiFi network controllers and security systems including e-mail or WWW traffic filters.
Containers are a new virtualization trend. Conterization software such as Docker enables the
construction of prototype images including all the necessary libraries and setting required by the
applications. Contrary to the regular virtualization containers divide the resources of the operating
system they are booted on. Virtualization on the operating system level has a few advantages with
the biggest one being developer, testing, and production environment unification that directly
influences the deployment speed and decreases the error number during software update uploading.
Containers are perfect for the horizontal resource scaling.
Every business should have data collection space. Depending on the conception, whether a company uses cloud solutions or opts for using its own IT infrastructure, it should choose disk array or a set of data collection arrays.Read more about disk arrays
vSAN double-node cluster
vSAN is the WMWare solution used for the hyper-convergence infrastructure deployment. The platform contains the elements enabling the calculation, net, and data carrier layer software definition.More about vSAN service
Azure Site Recovery and Azure Backup - company data protection
Microsoft Azure cloud services provide devices for keeping the work continuity and post-failure data recovery. Preserving work continuity is of crucial importance for business applications. A lack of access to the key business applications is often connected with company work stoppage and high financial loses.More about Azure Site
WLAN wireless network controller
The features and functionality of a manageable WiFi wireless network. A stable wireless network is especially important for the industrial solutions and a means to an end can be the deployment of a WiFi network controller.More about the wireless network controller.
Local computer network segmentation
VLAN virtual local networks enable a physical division of a computer network into isolated logical segments. A physical computer network can be divided into logical segments in which the flow will be separated and possible only inside a certain segment.More about the local computer network.
