What is XaaS?

EVerything as a Service (abbreviated XaaS) is a generic term that describes the consequence of ultimately purchasing “everything” as a service within cloud computing.

From applications to runtime environments to servers, this also includes people for whom costs arise primarily from their use.

The three most common sub-terms for this are Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS), which are represented hierarchically via the SPI model - with SaaS at the top, building on IaaS with PaaS as a mediating layer in between.

The basis of XaaS is Software as a Service (SaaS)

SaaS refers to applications that are provided over the Internet as a service IT outsourcing be used. Prominent examples of this are the cloud application Office 365 from Microsoft, the Adobe Creative Cloud and Cisco WebEx meetings

The customer receives the latest version of the software based on a subscription model and can book additional functions or services, such as larger storage space or a higher number of meetings, for an additional charge. Due to the up-to-dateness of the software used, the danger can arise IT vulnerabilities  be reduced.

Common advantages of SaaS, the basis of XaaS, are increased flexibility with lower investment risk for the user. However, this is counteracted by the dependence on the service provider and ISP.

Platform as a Service (PaaS) is also part of the core of XaaS

PaaS is understood to be the provision of a runtime or development environment for which payment must be made (on demand). Well-known representatives of this are Microsoft Azure and the Google App Engine. Microsoft's Azure is used to provide and scale applications for the user in a network of data centers distributed all over the world, which is maintained by Microsoft. The Google App Engine primarily serves as a platform for developing and hosting web applications.

The advantage for the user of PaaS is that he always has the latest version and does not have to worry about upgrades outside of his applications. The limitation to the cloud provider's specifications, such as the use of the programming languages ​​that are supported, can be seen as a disadvantage.

In addition to PaaS and SaaS, Infrastructure as a Service (IaaS) also forms the basis of XaaS

Instead of the classic purchase of computer infrastructure, IaaS involves renting it.

The best-known provider of this business model is Amazon with its Elastic Compute Cloud (EC2) and its Simple Storage Service (S3). S3 is a scalable and cost-effective, high-speed web service designed for online backup and archiving of data and application programs. Especially in times of malware like Emotet Secure backups for company data are very important.

EC2, in turn, is a web-based service that allows its customers to run application programs on a variety of virtual machines.

Advantages based on IaaS include intercepting load peaks or freeing up idle capacity through easy scalability, software testing on many different platforms and making applications affordable through one-time use.
