What is XaaS?


Share on

XaaS… What exactly is it? Pronounced “zass”, this is a concept that is regularly mixed up with SaaS and which means “*X* as a Service”, the “X” standing for “Everything or Anything”. 

So, what exactly are they and how are they defined? What are the advantages and disadvantages? Can it be easily implemented? We'll answer all of these questions in this article but, first of all, let's put a more specific definition down for this concept.

Definition: What is XaaS?

The term XaaS is an acronym for “Everything/Anything as a Service”. It's a concept which groups together all categories of cloud computing technologies and services.

This concept also covers the notion that any IT function can be seen to be a service for businesses; notwithstanding with the specificity that the consumption models associated with it are flexible.

This flexibility is generally characterised by the service on demand and a high degree of personalization of offers in relation to “traditional” offers.

Let's take a look at the history of XaaS

To trace back to the roots of XaaS, we need to go all the way back to the 2000s and the dawn of the cloud computing era.

It was at this time that businesses began to digitalise their infrastructure. This digitalization enabled them to boost flexibility whilst considerably reducing costs.

It's within this context that the concept of SaaS (Software as a Service) came to be. It stands testament to companies' desire to use applications that are hosted in the cloud, rather than software which tends to be heavy and installed locally.

Following on from SaaS, new terms were coined, such as PaaS (Platform as a Service) and IaaS (Infrastructure as a Service). It wasn't until the 2010 decade that the term XaaS emerged, referred to the growing trend of shifting everything over to the cloud.

The different types of XaaS - Examples and case studies

As we explained above, the term XaaS is used to cover all “as-a-service” solutions. Here are a few concrete examples of its use:

  • SaaS (Software as a Service): Salesforce, the Customer Relations Management platform is an SaaS solution
  • PaaS (Platform as a Service): Microsoft Azure App Service and AWS Elastic Beanstalk are great examples of platforms designed for the development, deployment, and management of web applications.
  • CCaaS (Contact Centre as a Service): This term refers to solutions for contact centres that are 100% hosted on the cloud. This is the case for Ringover.
  • IaaS (Infrastructure as a Service): Google Compute Engine is an IaaS service developed by Mountain View. It features flexible and customizable virtual servers that can be tailored to specific needs.
  • DBaaS (Database as a Service): Oracle offers a 100% automated database through which businesses can develop and deploy application workloads.
  • NaaS (Network as a Service): This is a mode in which businesses can subscribe to network service offers from suppliers such as Cisco with Meraki, for example.

What are the advantages of XaaS?

Each type of XaaS enables users to access specific advantages. For example, a CCaaS enables a contact centre to boost agent productivity and facilitates the implementation of an omni-channel client experience.

Nevertheless, there are some common benefits offered by all XaaS:

Reduced costs

One of the main advantages of XaaS is the budget savings that they allow businesses to make, whether it be in terms of investments, maintenance, or human resources.

There are swings and roundabouts, as costs are incurred both in the operational and investment aspects, but these costs are also lower for businesses.


The second advantage that we need to highlight is the flexibility offered by XaaS. Cloud services allow for easy adaptations to be made, whether they're in response to a team's workload, sector trends, or market developments, etc. 

For example, if a growing business knows that it's going to have to recruit new talents to reinforce its sales teams to achieve its goals, it can increase the number of licenses for its prospecting tool in just a few clicks in the dashboard of its supplier's solution.


With great flexibility comes great scalability. With XaaS, companies instantly become more scalable. This scalability is also down to the fact that, overall, tools can be quickly developed thanks to the new technologies driving them. 

XaaS enable businesses to evolve at the same pace as these technologies, quickly reacting to emerging trends. This has been the case globally observed with the democratization of Artificial Intelligence, which is working its way into existing tools.


The final key advantage offered by all XaaS is, of course, their capacity to be available and accessible anytime and anywhere. 

The cloud overcomes tool and service availability barriers, thus bypassing the need for heavy hardware infrastructure in business' premises. 

All you need is an internet connection and a terminal that's compatible with the XaaS solution in question. 

With Ringover, you can access your phone system via your smartphone, tablet, or computer, no matter where you are in the world, as long as there's internet access.

What are the disadvantages and risks of XaaS?

Of course, XaaS do have their down sides, of varying impact according to the complexity of the project and the technologies used. So, you'll need to take these factors into account. Here are a few examples:

A certain level of dependency on the provider

When it's a project outsourcing an infrastructure to the cloud, in part or in whole, this creates a certain dependency on the service provider. 

In other words, responsibility for at least some part of the business will essentially be passed onto the supplier and its capacity to offer a reliable and high-quality service. So, you need to make sure that you choose a high-quality service provider and that you have a back-up solution planned just in case any issues arise.

Data security

When you're using cloud-based solutions that are hosted by a third party, the question of data security naturally crops up. 

The supplier may also go through a service provider for the hosting of its solution or client data. As a result, it's essential to make sure that everyone is respecting the applicable data protection regulations.

Hidden costs

While the cloud does reduce costs, it can also come with hidden costs, so you need to ensure that you clear up exactly what you'll need to pay with the service provider before signing the contract. Some of these costs that we're thinking of are:

  • Customization costs
  • Termination costs
  • User training costs
  • Integration into business tools

So, we highly recommend assessing each solution based on your company's current and future needs, in order to reduce or anticipate these costs as best as possible.

The key facts to remember about XaaS

XaaS, or "Anything as a Service", is revolutionising the way in which businesses are consuming and creating services. For businesses, XaaS offer an adaptive model with some great advantages, such as flexibility, scalability, access to cutting-edge technologies, and budget-saving options. 

Over the years, and as technology has progressed, different types of XaaS have been developed, to the stage where they're now standard for some sectors. SaaS and PaaS are great examples, where you can see the dependency of businesses in tech sectors on these solutions. 

Although it's extremely practical and powerful, XaaS does come with some down sides, such as dependency on the supplier, hidden costs, and security issues that must be systematically assessed and resolved, as they're certainly not issues that can be ignored or underestimated.
