What is a cloud service?

Cloud services include software, data storage, databases, servers, networks, computing, and other services.

Accessible on-demand through the internet. As these services are externally located, they are referred to as a cloud, thus the term "cloud services." Anyone can use these services as long as there is access to the internet.

How are they different from traditional services?

Not long ago, users had to install software on their hardware and store their data locally, however, by making software.

And hardware accessible on-demand through the internet, cloud services eliminate the need for software installation and

Local hardware. This gives users the freedom to use services anywhere and on any device.

An example of this is Google's popular email client Gmail. Users can use Gmail anywhere and on any device without installing it. Any software.

Cloud services for businesses and private

As cloud services are unrestricted and come with almost no restriction compared to traditional services, they are trendy for Private use and rapidly gaining popularity in the business world, contributing to IT modernization. With the increasing user base, cloud services diversified quickly to fulfill specific needs.

Cloud services are classified into the following four categories depending on the components used: IaaS, PaaS, SaaS, and DaaS. Let's take a closer look at each of them.

What is SaaS?

By a browser client. With that, customers can use the software without being concerned about computing resources, other money, and time-consuming things.

SaaS has the following benefits:

• No need for software installation

• Data can be stored online.

• Any device can access software and data.

• Data can be shared quickly and effectively between multiple users.

• Highly advanced software can be used almost instantly

SaaS examples:

• Gmail

• Google Drive

• Google Calendar

• Google Sheets

• Hangouts

PaaS stands for Platform as a Service. The provided service is a platform that allows users to develop, manage and run applications.

Through the internet. This can include middleware that connects applications with operating systems, programming languages, web servers, and other parts that build an environment that enables fast development and easy management of applications. In comparison to SaaS, Paas is very flexible when it comes to software as you can use existing software as well as in-house developed. Software, depending on your needs.

PaaS has the following characteristics:

• By providing a ready-to-use development environment, you save development costs and time.

• You don't have to worry about maintenance and backups as the service provider handles them. The service provider takes them.

• As the infrastructure is provided and set up by the service provider, you can start using the service right away.

• PaaS gives developers much freedom, such as choosing previously used applications for development and running them on the platform.

An example of PaaS is the Google App Engine on the Google Cloud Platform. It lets users deploy the application without spending time on the backend as it allocates and scales resources automatically and provides other automated tools for application development and management.

IaaS stands for "Infrastructure as a Service." The provided service is a complete infrastructure accessible through the internet Networks, servers, operating systems, and anything else required for building and running systems. Unlike PaaS, the User controls the backend, can specify hardware components and sets up the operating systems precisely to their liking. After That, the user can develop and run a design on top of it.

The user has much more freedom than SaaS and PaaS but more responsibility. More technical expertise is required to set up the Hardware, servers, network, security, and other components.

IaaS has the following characteristics:

• It comes with a ready-to-use development environment.

• It gives the user the freedom of specifying hardware specs and setting up operating systems to use over the internet.

• Provides easy-to-use resource scaling options

• Saves the user hardware maintenance and repair costs

An example of IaaS is the Google Compute Engine on the Google Cloud Platform. It allows users to set up virtual machines (VMs)

That operates similarly to traditional computers. However, you can specify the specs, choose and set up an operating system, and change the resources' scale up or down at any given time. As Google provides it, you don't have to pay for anything. Else but the usage.

What is DaaS?

DaaS stands for "Desktop as a Service." The provided service is a desktop environment accessible through the internet and sometimes referred to as a "cloud desktop" or "virtual desktop." The hoster offers all the required resources to run the desktop environment And any application, storing and saving data for each session.

DaaS can be divided into three different categories.

Private cloud DaaS

Private cloud DaaS is a desktop environment specifically developed and provided to only one company. The company can choose the Operating systems, software, and all other components as it likes and customizes them to its needs. By that, private cloud DaaS Gives the user a high level of security.

Virtual private cloud DaaS

Virtual private cloud DaaS is a desktop environment built and running on the hoster's IaaS and PaaS. This gives the user a relatively—high level of customization and security.

Public cloud DaaS

Public cloud DaaS is a desktop environment with selected OS and software options offered and used by multiple companies.

Simultaneously, it is less customizable and secure than private cloud DaaS and virtual private cloud DaaS.
