What is Cloud Computing (Beginners Guide)
Cloud computing is a sort of distributed computing that involves storing, processing, and managing data using shared resources such as networks and servers. This makes it a valuable tool for organizations, as it allows them to swiftly and easily access large amounts of data without investing in expensive gear or software.

What is Cloud Computing?
At its core, cloud computing is based on several fundamental principles. These include virtualization, scalability, elasticity, and utility pricing.
Virtualization allows users to access software as if running on their machines, even though it may be hosted elsewhere. This makes it easy for businesses to share data and resources securely and efficiently.
Scalability refers to the ability of a system to handle increased demand by adding more resources, such as servers or storage. This is essential for businesses, allowing them to grow their operations without investing in new infrastructure.
Elasticity is the ability of a system to scale up or down quickly in response to changes in demand. For example, a cloud computing platform may be able to increase the number of servers it is using during high-traffic periods or reduce its resources when demand is low.
Utility pricing is the usage pattern of users that drives pricing in cloud computing. To reduce the overall costs, a public utility provider segments its billing structure according to the resource usage of each user’s account. The usage-based pricing model offers an alternative to per-unit pricing that charges based on how much customers use rather than basing the bill on the number of units consumed.
Types of Cloud Computing
Cloud computing, in simpler terms, means various types of computing services, which are delivered over the internet and can be accessed by anyone with an internet connection. There are three types of cloud computing services:
- IaaS (Infrastructure as a Service)
- PaaS (Product as a Service)
- SaaS (Software as a Service)
1- IaaS (Infrastructure as a Service) is an ever-growing cloud computing model. Businesses can rent IT infrastructure – including servers, storage, and networking – on a pay-as-you-go basis from a service provider.
Businesses that use IaaS can avoid the high upfront costs of investing in their on-premises infrastructure, and they can benefit from the flexibility and scalability of the cloud. IaaS also allows businesses to outsource the management of their IT infrastructure to the service provider without stretching internal resources and focusing on other priorities.
There are many different providers of IaaS services, and each offers a unique set of features and pricing options. To pick a reliable provider for your business, it is essential to consider security, performance, and compliance requirements.
2- PaaS (Product as a Service) is a cloud computing model that provides a platform for developers to create, deploy, and manage applications. PaaS includes everything you need to run an application, including the operating system, web server, database, and runtime environment. It is specifically designed to make it easy to develop and deploy applications in the cloud.
Moreover, PaaS is an excellent option for developers who want to focus on their code and not worry about managing infrastructure. It can also deploy applications without provisioning and configuring servers quickly.
PaaS providers offer a variety of features and services, such as storage, databases, monitoring, and scaling. A few service providers offer additional services such as machine learning or artificial intelligence.
3- SaaS (Software as a Service) refers to software delivered through the internet. This type of online delivery allows users to access and use their software remotely via a cloud. SaaS eliminates the downtime from installing new versions, which can be time-consuming when purchasing software packages. It also provides updates automatically, based on security requirements or bug fixes, etc.
Although there have historically been some concerns about data security when using SaaS applications, many businesses today recognize the benefits of this emerging technology trend. One famous example of a SaaS application is Salesforce, a CRM tool used by sales teams worldwide.
So now you know what SaaS is! However, knowing how it works requires understanding what a Software as a Service (SaaS) environment is and how the cloud technology delivers those applications to users.
Benefits of Cloud Computing
Cloud computing has several benefits that have made it very popular. One of the main benefits is its scalability. This means that businesses can quickly increase or decrease their use of resources as needed without making significant upfront investments.
Another key benefit is the flexibility it offers. Businesses can choose from various services depending on their needs and can easily switch between vendors if needed. Additionally, cloud services offer greater security than other traditional forms of IT, as data is stored remotely and protected using advanced encryption techniques.
Overall, the benefits of cloud computing make it an attractive option for businesses looking to streamline their operations, reduce costs, and stay competitive in the fast-paced world of modern business.
- High speed & quick deployment
- Access to a broad range of technologies
- Cost savings
- Globally scalable
- High performance
- Minimal tasks that improve productivity
Cloud computing offers high speeds and quick deployment, allowing you to access the technologies you need for your business quickly. This flexibility enables your company to stay agile and responsive in today’s fast-paced business environment.
Cloud computing also gives you access to various technologies, from cloud storage and computing to big data and machine learning. This broad range of technologies can help you meet the needs of your customers and employees without having to invest in expensive infrastructure.
Cloud computing can also save you money on your IT costs. By using the cloud, you can pay for only the resources you need when you need them. This can help you reduce your overall IT costs and the cost of specific projects.
You can potentially scale your resources up or down based on your unique needs with cloud computing. This scalability can be a significant advantage for businesses growing or experiencing fluctuations in demand.
Cloud computing also offers high performance and reliability, thanks to the global network of servers that support it. This allows you to run your applications and workloads at peak efficiency, with minimal downtime or service interruptions.
Finally, by taking advantage of cloud computing, you can free up your IT staff to focus on more strategic tasks to improve your company’s productivity. Using the cloud can automate many day-to-day tasks that consume valuable time and resources.
Day-to-Day Examples of Cloud Computing
Many tech-savvy enthusiasts are familiar with cloud computing, but they may not know its meaning or how it works. This model allows users to access programs and files in a remote location via internet connections.
- One example of cloud computing in action is how many businesses store and manage their data. Rather than maintaining expensive servers for all of their files, these companies can rent space from an external provider and access their data remotely via the internet. This helps them scale up or down their storage needs quickly and save money on hardware and maintenance costs.
- Another typical example of cloud computing is how people access software programs. Rather than having to install these programs directly onto their computers, they can use them via an internet connection. This enhances greater flexibility and mobility, as users can access their schedules from any location with an internet connection.
- Cloud computing is an increasingly popular and helpful model for delivering services in various contexts. Whether you are investing in a small or medium-sized business and looking to store your data or an individual seeking access to software tools, the cloud offers many advantages that can help make your life easier. So keep using cloud computing today, and enjoy the benefits that it has to offer!
- Google Drive and Dropbox are two famous examples of cloud computing in action. These services allow users to store and share files via the internet, making it easy to access and manage your data from anywhere. If you are starting a new business, collaborating with colleagues, or simply backing up important documents, these tools can help streamline your workflow and make your life easier.
