Technology has really improved the nature of conducting business and transactions by turning the analog ways into digital ways. Through the internet, distance and location factors are eliminated making it easier to interact with others from all over the world and share content. People find the internet quite convenient due to being allowed to purchase goods and service online and paying too at the comfort of their homes. All online transactions are made possible by the internet infrastructure which is the underlying foundation that enables online activities. The internet can be defined as an interconnection of many networks that connects computers and users.
The physical or hardware components, software and programs, content and transmission media combine to form the internet infrastructure. When people are using the internet, they trade traffic which is basically the videos, movies, pictures and other types of content sent over the internet. Data centers are the backbone of the internet meaning that they are very crucial for the internet to be available and usually consist of numerous servers in one building. In order to run the internet, there must be optimized and high performance computers that can be used to efficiently perform the various processes which are called servers. Data centers could be owned by single entities or multiple entities that make use of the servers to offer their products and services.
For users to enjoy the products and services offered by the content providers, the content providers depend on the datacenter companies to store the content. Without the internet infrastructure it could be impossible to communicate or even share content with others over the internet. When numerous service providers own the data centers whereby each one gets a certain section allocated, it leads to creation of multi tenant data centers. The data centers offer a variety of services that include web hosting and domain name services, storage, backup and data processing services. Online services require content to be availed which is made possible through the service providers uploading content onto the servers. When someone searches for information or content over the internet, the data is acquired from the servers and made available.
Service providers use websites to avail their services and as such requires web hosting services to get space allocated. Websites are accessed through entering specific addresses or names which are given through domain name services. Data storage and backup services are offered to safely and securely store information and content in the servers and enabling access. Public networks are not very safe and those intending to send and receive sensitive information require virtual private networks. Virtual private networks also make it possible for users to access remote computers over the internet via encrypted mechanisms. When data is encrypted, it secures the data from hackers and other threats since one must prove their identities to get access.
