What is a Cloud-Based System?
First published: January 2, 2022 @ 6:00 pm
Cloud-based system is a term we use to describe the hosted system on the Internet. It’s an increasingly popular way to deliver web applications to users.
It allows companies to access software applications from anywhere, with the benefit of centrally managing their configuration and deployment.
This article explains what a cloud-based system, the different types and the ways you can use it for your organization.
You will also learn about the benefits of cloud computing services in terms of cost savings, flexibility and security.
Instead, users interact with these applications through various devices such as tablets, mobile devices or desktop computers using browsers like Internet Explorer or Chrome.
We access these applications over the Internet and users can use them anywhere (location) and at any time with an internet connection.
Cloud-based systems are based on the concept of virtualization (virtual server). Virtualization means that a computer system comprises hardware resources, software applications, data and services which are not present physically in the computer.
Instead, we host them on remote servers over the Internet or other communication networks. This allows us to make different systems out of one physical computer.
For example, it is possible to create different virtual computers using one physical computer by assigning different resources such as memory, hard disk space, processing power etc.
Similarly, it is possible to create multiple websites on one server by assigning different web servers to each website.
The Cloud computing services provide users with access to various web applications without requiring any installation or maintenance on their computers.
The application runs in a virtual environment provided by cloud service providers, which comprises data centers and network systems where they host these applications.
Cloud providers provide software applications such as SaaS (software as a service) or PaaS (platform as a service). We usually pay the cost of using these services through monthly subscription basis fees based on a usage plan chosen by users.
There are three main types of cloud computing or cloud-based services, such as:
This is a form of cloud-based system where software applications are provided to users on demand through the Internet. SaaS is available for different types of applications including desktop, mobile, gaming and web-based applications.
The advantage of using SaaS is that it allows users to access the application from anywhere at any time without having to install or maintain the application on their computers. This makes it possible for users to access these applications without being dependent on hardware resources.
However, the disadvantage of SaaS is that the service may be unavailable at times because there are so many applications available in the market, and it’s not possible for all of them to be available at all times.
Another disadvantage is that software provided through SaaS can have bugs which can cause problems for users.
PaaS provides developers with access to pre-built application hosting environments. The platform hosted by PaaS provider allows developers to create web apps using programming languages such as Java, Ruby or PHP.
End users can access these apps through different devices such as mobile phones, tablets or desktop computers.
IaaS is similar to PaaS in that it provides developers with access to pre-built application hosting environments. However, IaaS provides resources, such as network systems and servers.
It allows developers to build their own apps by adding the necessary functionality to these resources.
This means that IaaS is more expensive than PaaS because of the additional cost of building and maintaining these resources, or the cloud infrastructure servers.
Cloud-based system provides many benefits which can be used by organizations or businesses in different ways depending on their goals and needs:
Cloud-based system provides organizations with flexibility in terms of resource allocation. Instead of investing in hardware and software, which can be expensive, they can use cloud providers to provide the needed resources at the right time.
This allows them to reduce costs associated with hardware purchase and maintenance costs. They can also shift workloads from traditional hardware to cloud-based systems when necessary without having to worry about scaling up or down due to lack of resources or maintenance issues on existing systems.
Using cloud-based systems results in significant cost savings because it reduces the number of hardware and software purchases that organizations have to make. They also don’t have to pay for maintenance costs associated with these hardware and software systems.
The cloud technologies are more secure than traditional computer systems because they are hosted on remote servers. It is not possible for attackers to break into the systems of cloud providers because they are not physically present in the computer systems.
The use of encryption protocols like SSL (Secure Sockets Layer) ensures that sensitive data is protected against hackers while transmitting through the Internet.
A cloud-based system can help organizations save time by reducing deployment times associated with different types of applications such as desktop, mobile, web, business applications, and gaming applications.
Instead of having to develop new apps from scratch, developers can access pre-built app development environments which reduce development time and cost.
Developers can access a wide range of apps using a single platform, which reduces learning costs associated with app development and provides access to a wider range of features in apps compared to custom-built apps.
It’s easier for organizations or businesses to manage cloud-based systems because it doesn’t require additional hardware or software purchases or maintenance costs when compared to traditional computer systems which are hosted on local servers.
This means that organizations don’t have to spend time managing different hardware and software systems.
Organizations or businesses can use cloud-based services to reduce development costs associated with creating apps by using pre-built application environments provided by cloud providers.
These app development environments are created by developers using different programming languages such as Java, Ruby or PHP. These languages are designed to allow developers to create complex apps quickly and easily.
