Cloud computing is a network-based computing model that allows users to access integrated hardware and software services over the internet, primarily on a pay-as-you-go basis. It offers various services, including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS), making it accessible to both individuals and businesses. While it enhances ease of use and broadens computing capabilities, it also raises concerns about data security and user control over information.
Cloud computing - new class of network based computing
- 2. What is Cloud Computing? Cloud Computing is a general term used to describe a new class of network based computing that takes place over the Internet, basically a step on from Utility Computing a collection/group of integrated and networked hardware, software and Internet infrastructure (called a platform). The hardware and software services are available to general public, enterprises, corporations and businesses markets
- 3. What is Cloud Computing?
- 4. Types of Cloud. There are different types of clouds that you can subscribe to depending on your needs. As a home user or small business owner, you will most likely use public cloud services.
- 6. What is the purpose and benefits? Cloud computing enables companies and applications, which are system infrastructure dependent, to be infrastructure-less. By using the Cloud infrastructure on “pay as used and on demand”, all of us can save in capital and operational investment! Clients can: Put their data on the platform instead of on their own desktop PCs and/or on their own servers. They can put their applications on the cloud and use the servers within the cloud to do processing and data manipulations etc. 6

- 11. Cloud Summary Cloud computing is an umbrella term used to refer to Internet based development and services A number of characteristics define cloud data, applications services and infrastructure: Remotely hosted: Services or data are hosted on remote infrastructure. Ubiquitous: Services or data are available from anywhere. Commodified: The result is a utility computing model similar to traditional that of traditional utilities, like gas and electricity - you pay for what you would want!

- 13. Conclusion The cloud provides many options for the everyday computer user as well as large and small businesses. It opens up the world of computing to a broader range of uses and increases the ease of use by giving access through any internet connection. However, with this increased ease also come drawbacks. You have less control over who has access to your information and little to no knowledge of where it is stored. You also must be aware of the security risks of having data stored on the cloud. The cloud is a big target for malicious individuals and may have disadvantages because it can be accessed through an unsecured internet connection.
