In this cloud computing tutorial, we will discuss, what is cloud computing services, their types, their benefits, and cloud computing basics.
Cloud computing services provide many benefits to your business which helps you grow immensely in a short time.
This is a technology of the future that will bring a lot of changes in the world of the internet in the coming years.
The term “cloud” refers to the cloud symbol in the IT industry used to describe an Internet network or Internet cloud.
Cloud computing is popularized by three big tech companies Amazon, Google, and Microsoft Azure.
Let’s get start the tutorial with cloud computing basics.
What is Cloud Computing Services and How does Cloud Computing Work?
Cloud Computing Meaning and Basics
What is cloud computing services? Cloud computing is using a system or network of remote servers on the Internet to store, manage, and transfer data instead of a local physical server or a user’s personal computer.
By remotely hosting software, applications, and data, cloud servers free up the memory and computing resources of personal computers.
Not all clouds are the same and not one type of cloud computing is suitable for everyone. There are several different models, types, and service solutions available to help you.
For this, first of all, you need to determine the type of cloud computing architecture or cloud deployment to which the services will be implemented.
Do you know, How does cloud computing works?
Instead of purchasing or owning the cloud computing infrastructure of your business such as data centers, servers, storage, etc., enterprises can rent or lease from the cloud computing service provider to access their database storage via the Internet.
The main advantage of using cloud computing services is that business enterprises can significantly reduce their initial cost and the complexity of purchasing or maintaining their own IT infrastructure.
Instead of investing heavily in infrastructure, you now have options such as the pay-as-you-go methodology that allows you to charge only what you use and store.
Types Of Cloud Computing
There are mainly three distinct ways to deploy cloud services:
- Public cloud
- Private cloud
- Hybrid cloud
1. Public Cloud
A public cloud is a type of cloud computing in which third-party cloud service providers share their resources to the public via the Internet, like servers, virtual machines, applications, and storage.
Examples of public cloud are Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure.
2. Private Cloud
A private cloud is a type of cloud computing resource which owned, control and used solely by a single business or organization. Sometimes businesses also pay third-party cloud service providers to host their private cloud.
So it is clear that one in which the entire cloud services and infrastructure are maintained on a private network.
3. Hybrid cloud
Hybrid clouds are a combination of public and private clouds. It uses the technical characteristics of both. Therefore, it tied together by technology that permits application and data to be shared between them.
Because it facilitates applications and data to shift between public and private clouds. Thus it provides more scalability, flexibility, extra deployment options to optimize your business infrastructure and security.
What are the types of Cloud Computing Services?
There are 3 types of cloud computing:
- Infrastructure as a Service (IaaS)
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
1. Infrastructure as a Service (IaaS)
This is the most significant and basic category of cloud computing services. In Infrastructure as a Service (IaaS), you can rent cloud IT infrastructures, such as servers and virtual machines (VMs), networks, storage, operating systems from a cloud provider on a pay-as-you-go basis.
Basically, (IaaS) is a cloud computing service where businesses lease or rent servers for computing and storage in the cloud.
Users have complete freedom to run any operating system or application on a rented cloud server without paying the maintenance and operating costs of those cloud computing servers.
Benefits of Infrastructure as a Service (IaaS): —
- Infrastructure as a Service (IaaS) offers you the highest level of scalability, flexibility, security, and control over your IT resources.
- If a disaster or outage occurs, these types of cloud services allow access to data and applications from different locations. So you get uninterrupted data Continuity and fast disaster recovery.
- Enterprises can instantly increase and decrease cloud resources according to demand in cloud computing applications.
- IaaS has reduced the operating costs of enterprises. Now they focus more on enhancing core business activities rather than on IT infrastructure and computing resources.
2. Platform as a Service (PaaS)
Platforms as a service (PaaS) helps a lot for developers to create web or mobile applications. They can now develop it quickly without having to worry about installing or managing the major infrastructure of servers, storage, networks, and databases.
PaaS is a type of cloud computing service that provides an on-demand environment for the creation, developing, testing, distributing, and manage software applications.
Benefits of Platforms as a service (PaaS):
- With the use of platforms as a service, business enterprises have no need to manage the underlying infrastructure such as hardware and operating systems.
- PaaS allows you to be more focused on the management and deployment of your applications.
- SaaS helps you become more efficient because you no longer have to worry about resource planning, capacity scaling or purchasing, software maintenance, patching, or any other time-consuming tasks in running your application.
3. Software as a Service (SaaS)
Software as a service (SaaS) is a type of cloud computing service that delivering software applications over the Internet, on-demand, and usually on a subscription basis.
In SaaS, cloud computing providers not only host and manage the software application but also responsible for underlying infrastructure and support any maintenance, like software upgrades and security updates.
Benefits of Software as a service (SaaS): —
- With a Software as a service (SaaS) cloud computing service, you don’t have to think about how the service is maintained or how often the cloud infrastructure is managed.
- Now you only require to think about how you will utilize that particular part of software applications. That reduces your overall workload.
- Web-based email is a very good example of a SaaS cloud-based application. For example, when we use web-based email, you can send and receive email without managing email product operating systems and maintaining servers.
What is Cloud Computing Architecture?
Cloud computing architecture means that it is an essential part and sub-part of cloud computing. These parts contain:
- Front end platform (e.g. fat client, thin client, mobile )
- Back end platforms (e.g. servers, storage, security)
- A cloud-based delivery, and a network (e.g. Intranet, Intercloud)
These components combine to form a cloud computing architecture.
Cloud Computing architecture comprises various cloud components. We can broadly divide the cloud architecture into two portions:
- Front End
The front end refers to the client because it is utilized by the client and, it also includes the application or software that are needed to access the cloud computing services or the cloud platforms.
Example – Web Browser like Chrome, Internet Explorer, Firefox, etc.
- Back End
The back end is mainly used by the cloud service provider. It contains all the resources need to provide cloud computing services. It mainly includes virtual machines, data storage, servers, security network, deployment models, services, etc.
What are the main components of cloud computing?
Cloud computing services are used by all small, medium, and large businesses or companies to store information in the cloud. They can access it from anywhere on the Internet at any time.
The following are the components of cloud computing:
- Client Infrastructure
- Application/Apps Or Software
- Service (There are three types of services offers in cloud computing):
- Infrastructure as a Service (IaaS)
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Runtime Cloud

9. Quick Back-up and Data Restore
if your application is hosted on multiple cloud locations and for some reason, one regional remote server goes down, the traffic automatically shifts to the other regions cloud server without any interruptions to the end-users.
10. Cost Reduction and Cost Control
It is true that switching to the cloud in the early stages is a bit costly. But, if implemented correctly, you can easily reduce the overall capital investment in the rest of the phase.
One of the biggest benefits of cloud computing is its “pay-as-you-go” model, which does not force you to pay a certain amount.
Cloud computing eradicates the capital expense of buying, set up hardware and software. Now you have no need to set up and run data centers, servers, round-the-clock electricity for power, and an expensive cooling system.
Even you do not need a team of IT experts to manage the infrastructure. Overall it reduces your operation cost in a big way.
11. Cloud Disaster Recovery (Cloud DR)
Cloud disaster recovery is a type of various strategies and services aimed at public data or dedicated service providers to backup data, applications, and other resources.
If any technical disaster occurs, the affected databases, applications, and other resources can be restored to another local cloud data center and instantly resume normal operations for businesses.
12. Automatic Software & Application Updates
Cloud automatic update features regularly update your system with the latest technology. As a result, you always have up-to-date versions of the software as well as regular upgrades to the server.
Disadvantages of Cloud Computing
- Dependence of Internet connection, speed, and availability.
- Low availability during a technical issue.
- Risk of users’ data privacy because of the slight risk that user data may be accessed by others.
- This can be a security concern if the level of security goes down during the software maintenance or upgrade process.
- Cyber attacks are very common nowadays, so the biggest challenge is to stop them.
How many websites should I host on cloud hosting?
It depends on various factors like your requirement and budget etc. If you don’t have budget issues, and have enough money to invest in cloud hosting services, then opting for a cloud platform is a wise decision.
Finally, you can host as many websites as you want on the cloud platform.
What is the future of cloud computing?
Despite the long journey, cloud computing is still like a growing child and an early stage of adoption. Many companies are still waiting and considering which applications to move to cloud infrastructure and when.
However, from the data of the last 5 years, we find that the growth in cloud infrastructure and the number of cloud-based users is increasing very rapidly.
In the article What is cloud computing services, we discussed the basics of cloud and reviewed the benefits of cloud computing for business.
Cloud computing is on-demand access and the delivery of multiple services through the Internet.
All computing services resources include applications, servers, data storage, security, network tools, etc., and are hosted at the remote data center of the cloud service provider.
The main benefit of using cloud computing services is that business enterprises can substantially reduce their initial cost and complication of buying or maintaining their own IT infrastructure.
However, 20 years ago very few people knew what is cloud computing services, how they work and how it is beneficial for businesses. But now things have changed completely, people are aware of cloud computing.
