Overview of Everything as a Service (XaaS)
Everything as a Service (XaaS) :
Before only cloud computing technology was there and various cloud service providers were providing various cloud services to the customers. But now a new concept has emerged i.e Everything as a Service (XaaS) means anything can now be a service with the help of cloud computing and remote accessing. Where cloud computing technologies provide different kinds of services over the web networks. In Everything as a Service, various tools and technologies, and services are provided to users as a service. Before XaaS and cloud services, companies have to buy licensed products and install them, had to all securities on their site and provide infrastructure for business purposes. With XaaS, business is simplified as they have to pay for what they need. This Everything as a Service is also known as Anything as a Service.
Examples of XaaS :
As XaaS stands for “Everything as a service”, There are many examples. There are many varieties of cloud computing models like –
- Software as a Service (SaaS)
- Platform as a Service (PaaS)
- Disaster Recovery as a Service (DRaaS)
- Infrastructure as a service (IaaS)
- Communication as a Service (CaaS)
- Network as a Service (NaaS)
Database as a Service (DBaaS)
- Desktop as a Service (DaaS) etc.
SaaS provides many software applications like Google Apps, and Microsoft Office 365. Similarly, PaaS offers AWS, Heroku, Apache Stratos, and other sources relating to application development and testing. IaaS helps to deploy and configure virtual machines and manage these remotely. IaaS also provide services to Azure and Google Computer Engine.
Everything as a Service Model Examples :
- Hardware as a Service (HaaS) –
Managed Service Providers (MSP) provide and install some hardware on the customer’s site on demand. The customer uses the hardware according to service level agreements. This model is very similar to IaaS as computing resources present at MSP’s site are provided to users substituted for physical hardware.
- Communication as a Service (CaaS) –
This model comprises solutions for different communication like IM, VoIP, and video conferencing applications which are hosted in the provider’s cloud. Such a method is cost-effective and reduces time expenses.
- Desktop as a Service (DaaS) –
DaaS provider mainly manages storing, security, and backing up user data for desktop apps. And a client can also work on PCs using third-party servers.
- Security as a Service (SECaaS) –
In this method, the provider integrates security services with the company’s infrastructure through the internet which includes anti-virus software, authentication, encryption, etc.
- Healthcare as a Service (HaaS) –
The healthcare industry has opted for the model HaaS service through electronic medical records (EMR). IoT and other technologies have enhanced medical services like online consultations, health monitoring 24/7, medical service at the doorstep e.g. lab sample collection from home, etc.
- Transport as a Service (TaaS) –
Nowadays, there are numerous apps that help in mobility and transport in modern society. The model is both convenient and ecological friendly e.g. Uber taxi services is planning to test flying taxis and self-driving planes in the future.
