Cloud Computing is considered a revolution in the world of the Internet due to the advantages it brings. More and more organizations and businesses are using Cloud Computing services. So what is Cloud Computing? What are its benefits? What are the types of Cloud Computing? All of these questions will be answered by ParacelTech in the following article.
What is Cloud Computing?
Cloud Computing is the provision of server, storage, database, networking, software, analytics, and intelligence services over the Internet (‘the cloud’) to deliver rapid innovation, flexible resources, and economies of scale. Instead of owning and maintaining these resources yourself, you pay for cloud services you use, helping you reduce infrastructure operation cost
Simply put, Cloud Computing is the storing and running of data and applications on the cloud rather than on your local computer or any device you own. Then, these cloud-based applications and data are accessed via the Internet. This means that the workload is no longer on your computer or any device you own but is entirely processed on the cloud.
What is Cloud?
The Cloud (or cloud computing) is a building containing servers to provide services to customers. It is a massive data center. These servers perform various tasks such as running applications, storing data, processing data, hosting websites… All of them can connect to each other and can be accessed via the internet.
The History of Formation and Development of Cloud Computing
So, when was the term ‘cloud computing’ coined? It is known that in the early 1990s, after the establishment of Apple and Microsoft, the Internet was presented in a more understandable and clear manner, which attracted more interest in the networking field. Subsequently, IBM introduced its first PCs or MAC operating systems, which laid the groundwork for the emergence of cloud computing.
By the late 1990s, as the internet and IT devices were increasingly improved, Cloud Computing began to make a strong impact. Salesforce.com, when launched, became the first commercial website to offer a range of business applications. Gradually, many people recognized the value of Cloud servers and used them through services like Yahoo and email.
In 2002, Amazon introduced Amazon Web Services (AWS). The emergence of Facebook in 2004 created the concept of ‘cloud for individuals.’ Finally, in 2006, the term ‘Cloud Computing’ gained strong momentum as a series of Amazon’s EC2 services or Google Docs from Google were launched.
The Benefits of Cloud Computing
Throughout its journey from inception to the present day, Cloud Computing has brought about many benefits, including:
1. Speed
The diverse access capabilities of cloud technology enable you to innovate and develop rapidly. You can easily access necessary resources, from infrastructure services like computing, storage, and databases, to technologies like Internet of Things, machine learning, data warehousing, and data analytics.
The ability to deploy technology services quickly and more flexibly than ever before helps you move from ideation to execution more rapidly. This allows you to easily experiment and test new ideas to create better customer experiences and grow your business.
2. Scalability
With cloud computing, you don’t need to provision resources beyond your highest anticipated business operational needs in the future. Instead, you provide only the resources you actually need. You can easily scale up or down these resources instantly to meet changing business demands.
3. Cost Savings
Cloud Computing allows you to replace fixed costs such as data centers and physical servers with variable costs, only paying for the IT resources you use. Moreover, variable costs are also much lower than the costs you would have to bear on your own due to economies of scale.
4. Rapid Deployment Worldwide:
With the Cloud, expanding into new geographic regions and deploying globally can be done in just minutes. For example, AWS has infrastructure worldwide, allowing you to deploy your applications in multiple locations with just a few clicks. By placing applications closer to end users, latency is minimized, and their experience is improved.
Types of Cloud Computing Services
Most cloud computing services fall into four main types: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Serverless, and Software as a Service (SaaS). Depending on the requirements, different levels of control, flexibility, and management can be chosen for each type.
Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) is one of the fundamental cloud computing services. With IaaS, you can rent IT infrastruc
Platform as a Service (PaaS)
Platform as a Service (PaaS) is a service that provides an on-demand environment for developing, testing, deploying, and managing software applications. PaaS is designed to help developers quickly create web or mobile applications without worrying about setting up or managing the underlying infrastructure of servers, storage, networking, and databases needed for development.
Software as a Service (SaaS)
Software as a Service (SaaS) is software delivered as a service, distributing software applications over the internet on-demand and typically on a subscription basis. With SaaS, cloud providers host and manage software applications as well as the underlying infrastructure, handling all maintenance activities such as software upgrades and security patches. Users connect to the application over the internet, usually through a web browser on their phone, tablet, or PC.
Serverless Computing
Serverless Computing, also known as function-as-a-service (FaaS), focuses on building application functionality without continuously managing servers and the infrastructure needed to do so. The cloud provider handles setting up, scaling, and managing servers for you. Serverless architecture is highly scalable and event-driven, only using resources when a specific function or trigger occurs.
What are the benefits of Cloud Computing?
You may be using cloud computing without realizing it. If you use an online service to send emails, edit documents, watch movies or TV, listen to music, play games, or store pictures and other files, it’s likely that cloud computing is making it all possible behind the scenes.
Here are some specific examples:
Storage, Backup, and Data Recovery
Protect your data more cost-effectively—and on a larger scale—by transferring your data over the internet to an external cloud storage system that can be accessed from any location and device.
Streaming Audio and Video
Connect with your audience anytime, anywhere, on any device with globally distributed high-resolution audio and video.
Delivering Software on Demand
Also known as Software as a Service (SaaS), on-demand software allows you to deliver the latest versions and updates of software to customers – whenever they need it, wherever they are.
