What makes a good IT Infrastructure
For the ease of understanding the term IT infrastructure, its connecting between wall jack to panel jack. Putting it in these simple words makes the job easier for experts and not so experts in IT industry.
IT Infrastructure is combination of Hardware, Software, Networks and Environment to create, facilitate, manage and control the services. It is also about enabling people who operate on this domain. Supporting the facility with documentation, implementation and integration of the activity is also part of IT infrastructure.
A network switch is the device that provides connectivity between network devices on a Local Area Network (LAN). A switch can contain combination of ports that connect to other devices on network, this might include other switches, routers and servers. Switches allow two devices on the network to talk to each other without having to forward that traffic to all devices on the network. Switching is the practice of directing a signal or data element toward a particular hardware destination.
Another important device called, routers move bundles of data between networks. Routing enables different devices separated on different LAN’s to talk to each other by determining the next direction that will allow the network bundle to eventually get to its destination. We can actually define and give IP address manually.
Firewalls are the security devices that work on the laid rules for traffic on the network. A firewall is a device that sits in the network and manages the trusted and untrusted traffic on the network. It works s a barrier between various such unwanted entries from external network such as internet. Firewalls are security devices at the edge of the network. The firewall can be thought of as the guardian or gatekeeper.
Server is a type of computer or device on a network that manages network resources. Servers are often dedicated. meaning that they perform no other tasks besides their server tasks. On multiprocessing operating system, however, a single computer can execute several programs at once. A server in this case could refer to the program that is managing resources rather than the entire computer.
Different Types of Servers
Different types servers do different jobs, from serving email and video to protecting internal networks and hosting websites. There are many different types of servers, for example:
- File server:a computer and storage device dedicated to storing files. Any user on the network can store files on the server.
- Print server:a computer that manages one or more printers, and a network server is a computer that manages network traffic.
- Database server:a computer system that processes database queries.
A network server is simply just another computer but usually larger in terms of resources than what most people think of. A server allows multiple users to access and share its resources.
The physical plant or facility is all of the about the passive components network starting from buildings and server room, datacenter its cabling and connectivity. This is one of the most compromised lot of the IT infrastructure and proves to be the weakest link at times. The Server Rooms are the land of action for professional to manage IT Infrastructure of the office. It has Specifically designed racks, temperature inside the server rooms are maintained to keep servers remain cool. Air flow is maintained to get optimum usage. Power Distribution is done through different basic and advanced Power Distribution units, Mains Distribution units and Automatic Transfer Switches(ATS) with capabilities like metered, monitored, switched ( remotely). Cable management is done thru strong runways, Cable Trays and Ladder sets. We normally find raised flooring in the server rooms. Cabling for the IT Infrastructure is done keeping in mind the usage. The Data traffic is normally travelled on CAT 6/7 Cables or Fiber optic. This choice totally depends on the nature/type and speed of the data required.
The server room, or data center (in large organizations), can be thought of as the central core of your network. It is the location in which you place all of your servers and usually acts as the center of most networks.
Infrastructure Software is implanted to administer the whole network. It helps Accelerate workloads, simplify administration, enables to develop and deploy new applications. It also helps configure each of the network members ( Components) to its maximum capacities. It works as a bridge between various programs and makes the functioning smoother.
We don’t consider people as part of the network infrastructure. However, without competent well-qualified people in charge of running and maintaining our infrastructure, we will artificially limit the capabilities of your organization. At different levels of the organizations, there are specialty positions for each of the areas of the IT Infrastructure
