The Internet Infrastructure.
Technology has really improved the nature of conducting business and transactions by turning the analog ways into digital ways. The internet makes it possible for people in different continents to communicate and interact easily and also enables sharing of content. Businesses use the internet to market their products and services and customers are able to buy and pay for these services online as well. Online transactions and services can not be available if the internet infrastructure did not exist as it makes this possible. 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. The term servers refer to some specialized and optimized computers with the ability to handle the processes needed to run the internet. Data centers could be owned by single entities or multiple entities that make use of the servers to offer their products and services.
The data centers play an important role since all other service providers need them to be allocated space for storing their content. Most people think that telecommunications companies are important but actually the internet infrastructure is more vital compared to other firms. The data centers could also be divided into various sections and rented to content providers to create multi tenant data centers. Data storage and backup, website hosting, processing and domain name services are a few of the many services provided by the data center companies. Online services require content to be availed which is made possible through the service providers uploading content onto the servers. Once content is uploaded, a user can search for the content and be presented with the specified information.
Web hosting services are offered to those service providers who require some space allocated for their websites to be accessible. After getting a website designed, the owner also requires hosting services so that the website become accessible to online users. Domain name services are needed to give unique addresses to the websites so that users can access the websites easily. Virtual private networks are deployed when the information being shared is sensitive or needs higher security levels. Virtual private networks also make it possible for users to access remote computers over the internet via encrypted mechanisms. Encrypted access mechanisms keep personal information safe from threats and prevents unauthorized access into computers.
