The term infrastructure is like an umbrella covering the entire collection for software, hardware, data centers, facilities, networks and related equipments which may have been used to operate, test, manage or monitor general information technology services. Typically an IT infrastructure consists of these following components: Hardware which would ideally include all data centers, hubs, switches, computers, routers etc.
Software: ERP or Enterprise Resource Planning falls under this with productivity applications and also customer relationship management or CRM.
Network: The internet connectivity, firewall, network enablement and security.
Meatware: Users for network administrators, designers and developers and then finally the generic end users would access the IT service or appliance with the advent of the IT service developments that is more user-centric.
Satellite Communication: An artificial earth satellite is a facilitator which aids in communication like the telephone, radio and telephone transmissions. It simply means the reflection for the retransmission and amplification in between space and the earth. In satellite communication, signal transferring between the sender and receiver is done with the help of satellite. In this process, the signal which is basically a beam of modulated microwaves is sent towards the satellite. Then the satellite amplifies the signal and sent it back to the receiver’s antenna present on the earth’s surface. So, all the signal transferring is happening in space. Thus this type of communication is known as space communication.
Wireless Communication: Wireless communication uses electromagnetic waves to carry signals. These waves require line-of-sight, and are thus obstructed by the curvature of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated points. Communications satellites use a wide range of radio and microwave frequencies. To avoid signal interference, international organizations have regulations for which frequency ranges or “bands” certain organizations are allowed to use. This allocation of bands minimizes the risk of signal interference.
Mobile Infrastructure: IT administrators may only host Android operating systems; Apple’s licensing rules do not allow the iOS operating system to be abstracted from Apple hardware.When VMI is deployed, the operating system or application runs on a virtual machine (VM) in a remote data center. Any data associated with the OS and its applications is stored there as well. The OS is delivered to the endpoint through a secure remote communications protocol, which is decoded by a client app that runs on the mobile device. The OS and applications do not have to run locally on the mobile device. Some client apps can expose local hardware — such as GPS, accelerometers and cameras — to the remote OS, which makes the OS and its applications behave as if they were running locally.
Terrestrial Infrastructure: A content delivery network (CDN) aims at distributing/replicating multimedia content towards data centers in the transport network so that the content is served to end-users with higher service availability and performance by avoiding the effect of a website becoming virtually unreachable because too many people are hitting it or reducing the general load on websites servers in general. The terrestrial component of the hybrid architecture deployed for CDNs is typically made of wireline/wireless transport/access networks with data centers to distribute the content directly to fixed and mobile end users. The satellite component is usually based on GEO stationary satellites and connects the data centers to the service platforms.
