Well ladies and gentlemen, let's hover around and listen for a second...

The world has gone through a major transformation ever since the emergence of the industrial revolution,
which began in the 1700s. One of the areas which have significantly changed over the years is the field of
computer technology.

The first computer ever built had a processing power of 1.9 MHz and 64 Kb of memory- not even enough to keep a word document, but now computers are a hundred times faster and
contain more storage space.

However, this advancement has also brought along its own challenges; computer applications have become bigger in size and require more computing power to work excellently. This has placed a burden on the end-users because they have had to dig deeper to purchase the latest computers with enough storage space and ones that are powerful enough to keep up.

So... What is the solution to this problem?

The answer is cloud computing. Cloud computing allows people to run applications, programs through the internet without the need of buying and installing them on a physical computer.

With cloud computing, a user can access computer applications and programs that require a lot of computing power on a slower physical computer from anywhere in the world as long as they have internet access.

They can also store data on the internet, as a result eliminating costs of buying new physical hard drives. The most common cloud computing types are:

SaaS
Saas which stands for Software as a Service is a service that uses Pay-per-use of software via the internet using a web browser or client application. With SaaS, a client needs not worry about the operating system which is supported by the application because SaaS is platform-specific which means you do not need to download the software and install it on a device.

As long you have good internet connectivity you are good to go.

Its subscription service comes in monthly or yearly plans and they are cheaper, unlike license-bought software which comes with a heavy price tag. Free monthly plans are also available but have fewer features than paid plans.

Examples of SaaS include Google Drive, Dropbox, Microsoft 365, and iCloud.

PaaS
PaaS stands for Platform as a Service. It is a type of cloud computing where the service provider offers a platform to its clients that helps them develop, run and manage business applications without them having to own and maintain an IT infrastructure. PaaS consists of a programing language execution
environment, Operating system, web server, and database.

The most commonly used PaaS platforms are Microsoft Azure and Amazon Web Services (AWS).

IaaS
Iaas stands for Infrastructure as a service and it offers cloud-based computer infrastructure services comprising of server, operating system, and storage. Some IaaS platforms like Microsoft Azure manage the infrastructure while allowing users to buy, install, configure and manage their own software.

The cloud servers can be accessed by a client`s dashboard or an API, giving them full access to the infrastructure. Its use includes web hosting, high-performance computing, and big data analysis.

DaaS
DaaS is the “new kid on the block” as far as cloud computing is concerned but it is already becoming an increasingly popular solution.

Desktop as a service (DaaS), as it is called, allows users to remotely connect to a virtualized desktop via the internet. Daas`s desktop operating system is installed and runs on virtual machines in the provider`s cloud servers and users can access the desktop using a web browser or a client application instead of accessing it locally. Picture DaaS as a personal computer on the cloud which does not have to be carried everywhere but can be accessed at any time as long as there is internet connectivity.

DaaS is so secure– you never have to worry about losing data when a computer crashes or
files getting corrupt due to computer viruses. Shells, a newcomer in the scene offers its clients DaaS
facilities via the SPICE (Simple Protocol for Independent Computing Environments), allowing them to
access their virtual desktops from different machine architectures.
