Cloud computing is a type of internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (such as networks, servers, storage, applications, and services). This paper discusses the cloud computing architecture and its benefits over traditional distributed computing systems.
The first use of the term “cloud” in connection with technology was in reference to telephone networks. The term has been used to describe different types of technical architectures ever since. In recent years it has become popular to use the term “cloud” in reference to computer networks or the Internet.
The word “cloud” is often used as a metaphor for the internet or remote data centers because they are both difficult for people to see or understand how they work. The main difference between clouds and traditional networking is that instead of each user having their own server hardware and software installed locally, users can now access everything they need from a central location via the internet.
A cloud can be private or public. A private cloud is one where all infrastructure is owned by a single organization. A public cloud sells services to anyone on the Internet. The most common type of public cloud service is IaaS (Infrastructure as a Service), which gives businesses all the benefits of using physical servers without having to buy or maintain any equipment themselves. Other popular types of cloud services include PaaS (Platform as a Service) and SaaS (Software as a Service).
Some advantages of using cloud services include:
– Reduced Costs: Cloud services are typically much cheaper than buying and maintaining your own hardware and software infrastructure.
– Increased Flexibility & Scalability: Cloud services can be quickly scaled up or down as needed without having to make any changes to your local infrastructure.
– Improved Disaster Recovery: With all data stored remotely in the cloud, it becomes much easier to recover from disasters such as fires or floods that could destroy on-premises data centers .
Despite these advantages, there are also some potential risks associated with using cloud services that organizations should be aware of before making the switch:
– Security & Privacy Concerns: As data is stored off-site on remote servers, there is an increased risk that it could be hacked or leaked . Organizations should carefully consider whether their data would be better protected if it were kept on-premises . – Vendor Lock-in : Once an organization begins using a particular vendor’s cloud platform , it can become difficult and expensive to switch to another provider . This could limit an organization’s future flexibility if its needs change or if problems arise with the current vendor .
