Technology runs dedicated servers ensure that the highest performance & reliability all within an affordable rate. Citrix is one of the largest server virtualization technologies. They use the latest XenServer to create a link between the hardware of the server and the operating system. This allows performing some management & maintenance jobs without causing any downtime on server which permits the server to perform much better as it is encapsulated by a virtualized. Cisco is known worldwide for their reputation in networking hardware for routers & switches.
The level of redundancy available on Cisco network allows to sustain multiple & simultaneous network hardware failures, as well as connectivity losses by utilizes BGP that can tolerate numerous provider failures, it is 100% sure that there is no downtime in the network.
Nagios is a powerful monitoring system that enables companies to identify and resolve IT infrastructure problems before they effect critical business processes. Nagios is monitoring 24x7x365 the servers. It monitors everything from your server temperatures, fan speeds, hard drive status to network status and utilization, which will be able to take care of any issues before they arise.
Cloud is a computing solution in the Internet, which shares computers resources instead of using software or storage on a local PC. In other words, the ease of access remotely computer sites provided by the Internet. It is describing a new supplement, consumption and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet.
The term cloud is based on the cloud drawing used in the past to represent the telephone network, and later used the Internet in computer network diagrams as an abstraction of the underlying infrastructure it represents. The idea of cloud is to deliver common business applications online which are accessed from a web browser, while the software and data are stored on servers.
The clouds have five main characteristics: on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. In other words, cloud computing is client-server computing that abstract the details of the server away – one requests a service. However, cloud computing may be conflated with other terms, including client-server and utility computing, and the term has been criticized as vague and referring to “everything that we already do”.
The majority of cloud computing infrastructure consists of reliable services delivered through data centers and built on servers. Clouds often appear as single points of access for all consumers’ computing needs. Commercial offerings are generally expected to meet quality of service requirements of customers and typically offer SLAs.
