Cloud systems: What they are and why use them

Cloud systems: What they are and why use them

December 1, 2020

Google Photos, Netflix, or Spotify are all well known cloud services that want to make your life easier. Just click a button in your browser and you have access to your photos and a wealth of movies and music. At the same time, they don’t take up any space on your computer and you do not have to worry about backups. You can use the cloud just as easily for any software at work.

What is “the Cloud”?

In short, the cloud is a global network of servers used to store and manage data, launch applications, or deliver content and services such as video streaming, webmail, software, or social media. Their great advantage is that they can be accessed remotely via the Internet and are basically available from anywhere in the world at any time.

SaaS: Software as a Service

Software as a service (abbreviated SaaS) is one of the many uses of the cloud. It provides an interesting alternative to the traditional model, in which you must create a server, install software, configure and further update it. For SaaS, the application is hosted and managed by the provider and made available to customers via the Internet. In practice, you do not buy the software, but you rent it from the provider, which has a number of advantages.

Why SaaS?

Access from anywhere

Access to applications is not limited to your personal computer. All you need is a browser and an internet connection, and you can connect from any device in the world.

Low purchase price

You do not need to purchase, install, update or manage any hardware, middleware or software. In general, you subscribe for a cloud software rather than buy it, so you save money on initial license fees.

Saves costs

With SaaS, you only pay for what you actually use. Providers usually offer different subscription options according to your needs or pay-as-you-go financing. In addition, the infrastructure on which the software runs is managed by the provider, so you do not incur any hardware or software maintenance costs.

No need to install or manage anything

You do not need to install any systems on your devices. All the responsibility for any errors and problems is transferred from your internal IT department to the provider’s team, which can respond immediately in case there is a problem.

Immediate updates

The SaaS provider takes care of updates for you. The latest version starts automatically every time you log in to the application.

Your data is safe

It’s really hard to lose data in the cloud. Server providers must adhere to the highest possible security standards, and SaaS also generally allows data to be restored from automatic backups. Providers must also be able to handle personal data well, so there is no risk of penalties.

Quick configuration and deployment

The SaaS application is already installed and configured in the cloud, you only need to register. There is nothing delaying deployment and launch.


You can usually choose from many subscription options and flexibly add or remove features that you need. SaaS will work for you even if your business grows or if you need to change the number of users. The servers themselves can also scale, so they work quickly and reliably, regardless of the number of users. Your application is therefore less likely to stop or crash.

In summary, SaaS can provide businesses with access to the latest technology and professional support at an optimal price.
