Cloud Computing

Cloud computing involves the offering of computing services to an enterprise instead of a product. Cloud computing services provide shared resources, software, and information to businesses as a utility over a secure interconnected network. Enterprises typically entrust cloud computing services with storing user data, software, and other sensitive information over an application programming interface (API) network and software as a service (SaaS). Users access the cloud computing-based applications through a secure web browser and shared services. Cloud computing essentially allows enterprises to operate relevant applications faster with minimal hassle. In addition, it works in tandem with information technology (IT) departments to adjust hardware and software equipment, such as servers, storage devices, and networking mainframes to meet a varying business demand.

What is the History of Cloud Computing?

Cloud computing draws similarities to the cloud diagrams used to depict the telephone network before the Internet’s inception. Cloud computing depicts the underlying infrastructure of the Internet using computer network diagrams. Technology’s ever-expanding resources have led to explosive growth in cloud computing programs. End users no longer need credentials to participate or control the technological infrastructure of existing cloud computing programs.

During the 1960s, John McCarthy spawned the notion that computation would become organized enough to be offered as a public utility. In 1966, Douglas Parkhill explored the foundational principles of cloud computing in his published book entitled, The Challenge of the Computer Utility. Other authoritative figures argue that Herb Grosch postulated that the entire world would connect on a series of terminals leading to fifteen major data centers. Cloud computing further evolved during the 1990s, wherein telecommunication companies began offering Virtual Private Network (VPN) services. These telephony companies used the cloud symbol to differentiate the responsibility between the provider and the end user.

Cloud computing uses this same concept to describe the abstraction of the Internet. After the dot-com stock market crash, Amazon and other key players revamped their data centers using cloud computing programs. Over the course of the last decade, many enterprises have used cloud computing programs, such as open-source platforms, Eucalyptus and OpenNebula. Efforts were also made by the European Commission to create a real-time cloud environment to shape the relationship between consumers and IT services.

What are the Different Cloud Computing Models?

Cloud computing programs consist of 3 different models, including platform as a service (PaaS), software as a service (SaaS), and infrastructure as a service (IaaS). The IaaS model, the most basic fundamental structure, offers computers raw storage, firewalls, networks, and load balancers on demand from large data centers. Local area networks (LAN) and wide area connectivity through carrier clouds come with the IaaS model. The PaaS model providers offer a computing platform with an operating system, programming language environment, database and web servers. The SaaS model providers install application software from cloud clients. End users do not manage the cloud infrastructure and platform using this model.

What are the Different Cloud Computing Applications?

Cloud computing can be applied in a variety of applications, ranging from word processing to customized computing programs. Clients may want to rely on cloud computing systems to operate and store data for many different reasons, including remote access linking to the Internet, hardware and software cost efficiency, and wide accessibility to corporate computer systems. In addition, servers and digital storage devices require a lot of physical space; however, cloud computing gives these companies the option of storing data on a third party’s hardware computer system. In theory, corporations would save money on IT support by causing less hardware problems than a heterogeneous networking system. Corporations that have a grid computing system could use the entire cloud network’s processing power. This would prove ideal for scientists and researchers that require powerful processing power to work complex calculations.

Education and Careers

Prospective students who want to pursue careers that involve cloud computing need to demonstrate competency within the IT field. The majority of employers seek out candidates who already have experience with one of the cloud computing pioneer companies, including Amazon, Google, Microsoft. andSalesforce. Some employers may want a combination of work experience and an underlying understanding of virtualization technologies, such as VMWare. Aside from those important aspects, prospective students will need a bachelor’s degree in engineering, computer science, or another IT related field. A cloud computing degree incorporates network and security architecture to fully understand the complexity of the cloud system itself. Graduates should look for an internship that introduces cloud migration, data center migration, and server consolidation. In addition, knowledge and experience in Java, Web services, SOAP, and Ajax will serve as pertinent requisites in obtaining a cloud computing degree. Students who wish to obtain a cloud computing degree should also have adequate communication, teamwork, and problem-solving skills.

Cloud computing has received recognition from large-scale corporations wishing to consume IT-related services in a cost-efficient way. More specifically, companies have developed an interest in easily accessing computational power, storage, and business applications from cloud services. As with other IT related issues, cloud computing can be enhanced to further move forward with its utility. Cloud computing implementation may result in a decreasing need for IT personnel in certain areas; however, it may allow other positions to open up in other IT departments. Developing a proficiency in cloud computing can eliminate this threat, but it may prove beneficial for individuals in some positions to expand their skills across an array of other related fields, especially for seasoned systems administrators.
