Virtualization, in computing, refers to the act of creating a virtual (rather than actual) version of something, including but not limited to a virtual computer hardware platform, operating system (OS), storage device, or computer network resources.We also help customer in virtualization of the server.
Hardware virtualization or platform virtualization refers to the creation of a virtual machine that acts like a real computer with an operating system. Software executed on these virtual machines is separated from the underlying hardware resources. The host machine is the actual machine on which the virtualization takes place, and the guest machine is the virtual machine. The words host and guest are used to distinguish the software that runs on the physical machine from the software that runs on the virtual machine. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or Virtual Machine Manager. Some of the benefit of server virtualization are:
- Reduce the Data center foot print
- Virtualization of the server help reduces number of server to be maintained and cost of purchasing server
- Virtual server are easy to be maintained with low impact on server down time and increased Uptime.
- Improved disaster recovery
- Isolate Applications
- Extend the life of older applications
- Save energy, go green
- QA/Lab Environments
- Faster server provisioning
These features allow you, as an administrator \ IT Consultant , to save time, reduce energy costs and even track IT assets, by automating tasks, and administrating any of your IT resources, at any time, from any place. Using this technology we can remotely administration your system using most secure remote administration tools, which can help us troubleshoot system issue without being physically present near the system. Remote administration can be reduce down time of the servers or resources.
We can help customer in installing and configuring Firewall to protect network from DOS Attacks, Spamming, Intrusion prevention, Virus, Malware and many more. We can also help in setting up VPN Connectivity so that employee can work from home without being physically present in office. We can setup interoffice connectivity using branch office tunnel so that employee can work in remote office and access resources from any office as though he is accessing locally.
We can help install and configure network security service like Network Protection service (NPS), Radius server for Authentication, Wi-Fi security, Antivirus Server and many more.. Network security consists of the provisions and policies adopted by a Organization to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the Organization. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access. Network security is involved in organizations, enterprises, and other types of institutions. It secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.
Most of the networks are subject to attacks from malicious sources. . Attacks can be from two categories: “Passive” when a network intruder intercepts data traveling through the network, and “Active” in which an intruder initiates commands to disrupt the network’s normal operation.
Types of attacks include:
- Port scanner
- Idle scan
- Denial-of-service attack
- Man in the middle
- ARP poisoning
- Smurf attack
- Buffer overflow
- Heap overflow
- Format string attack
- SQL injection
- cyber attack
