Abstract
The evolution of the Internet, the web development, the complexity of Internet businesses, as well as the volume of data and concurrent application users have determined IT&C specialists to design client/server applications on multiple layers, and on some cases even distributed solutions. The expansion of the Internet Service Providers networks and the accessibility of the Internet services have greatly increased the number of users that are using the Internet. This meant that new markets were opened for building new Internet businesses that rapidly grew in popularity. Because of the scaling issues generated by the large number of new users that are using Internet services, the IT&C specialists have developed solutions to share resources between companies in order to reduce operational costs. By scaling down internal resources and migrating their applications to cloud computing services, companies are cutting-down costs, increasing availability of their applications and increasing their security.
Highlights
The spread of the Internet helped the globalization effort of both companies as well as governments and NGOs
7 Conclusions At present, business, social, education, administration, health, culture, etc., virtually everything that surrounds us, awaits IT and communication solutions to automate all activities, devices and devices used in the production, services and current actions of organizations, citizens, the environment, and research in various fields
Cloud computing radically changes the way companies are using their IT applications, and the way in which information services are accessed by customers or users
Summary
Because of the expansion of global businesses, it means that companies need to server customers from all around the world, and try to provide them with the same quality of services This means building and managing new datacenters, improving the latency and bandwith of their applications and sharding data in order to prevent leaks and attacks from hackers. The Cloud Computing technology refers to “storing, processing and using the data on remote systems accesses through the Internet” [9] This means that consumers can access entensive resources without making expensive investments in infrastructure or specialized hardware. Hybrid Cloud, a combination of the two models, in which, the “IT infrastructure is composed of both the private and public Clouds, used as a whole and that used the same technology” [12] This technology is used when applications have both public and internal usage and there is a need to a secure layer for protecting company data. The main advances of the Cloud Computing technology or traditional architecture are presented by Mihail Dumitrache (table 1)
