The term XaaS was created with the idea of expressing Something as a Service or Everything as a Service. This acronym refers to the growing number of services delivered on the Internet instead of being supplied locally. XaaS is going to be an essential part of Cloud Computing.
The most common examples of XaaS are Software as a Service (SaaS), Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). The combined use of these three is sometimes referred to as the SPI (SaaS, PaaS, IaaS) model.
What do you mean by Everything as a Service?
Software as a Service (SaaS), a widely known concept, refers to an Application Service Provider (ASP) performing the hosting of a software and making it accessible from any location. This type of application was primarily driven by the concept of cloud computing allowing other types of activities to be offered as a service in addition to the software.
Since this model, other “aaS” models were developed dealing with other areas such as communication, infrastructure, monitoring and platforms. What they all had in common was an on-demand offering. The on-demand model was well received by the market because it operated by usage. If you use a service for 2 hours per month, you only pay for 2 hours of use. As more companies tried out this work flow, the use of the service started to be reflected in a change in service-related concepts.
The XaaS model continues to expand
One of the most interesting offers of XaaS is Monitoring as a Service (MaaS) intended to keep your local infrastructure in the cloud and having your systems and services automatically monitored. Our Sky.Saver solution, for example, uses the MaaS model, which allows for savings in infrastructure costs for those using AWS.
Communications as a Service (CaaS) is a term used by various telecommunication services. Under the umbrella term, CaaS, there are solutions such as Voice over IP (VoIP) also known as Voice as a Service (VaaS). In addition, there is Automatic Call Distribution (ACD), the automatic exchange of private branches (Private Branch eXchange – PBX).
Infrastructure as a Service (IaaS) is widely known thanks to AWS’ EC2 (Elastic Compute Cloud) service. Virtual servers and their resources (CPU, memory and disk space) are dynamically allocated and provisioned based on usage.
Desktop as a Service (DaaS) is a cloud service where backend infrastructure is hosted by a service provider in the cloud. The architecture of the DaaS provider is responsible for data storage, backup, security and updates. The user’s data is copied and made available on virtual desktops when they log in as well as when they are turned off.
Disaster Recovery as a Service (DRaaS) is used when a company replicates and hosts its physical or virtual servers to provide failover solutions in the event of a disaster. The provider will host your data in the cloud. It is especially useful for SMBs who do not typically own the infrastructure, technology or qualified staff to implement a disaster recovery plan on site.
Advantages of the XaaS model
Among the advantages of the on-demand model, particularly XaaS, is it makes SMBs able to compete with larger organizations. SMBs using these services can compete at a fraction of the cost needed to invest in the purchase of hardware, software and experienced staff to configure and maintain these services. Another advantage is the ease of acquiring a complete framework of services while creating a completely virtual company. Where can your operations be based? Anywhere.
XaaS is a concept practiced and leveraged far past the point of considering it just a theory. XaaS can help in numerous types of businesses and involves low initial investment and reduced startup times. By strategizing how you want to benefit from these models and a well-defined architecture, this will vastly improve your company’s overall operations objectives.
