Yes, it is to some of you. You would have heard about Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (SaaS).
XaaS is ‘Anything’ as a service. It’s pay as you go model of services related to cloud computing and remote access. You can use the service providers’ products, tools, technologies and others and pay for the services you used.
XaaS even includes Disaster Recovery as a Service (DRaaS), Communications as a Service (CaaS), Network as a Service (NaaS) and others. So the XaaS availability depends on the service provider. AWS (Amazon Web Services)is one of the service providers that provides Cloud Services.
Cloud computing is delivering different services through the Internet (data storage, servers, databases, networking, and software). When you store data on the cloud, you can retrieve them on demand. You may wonder what’s cloud storage. Let me give you a simple example. Google Drive is cloud storage. You save your data, files, pictures and documents on Google’s server. It’s nothing but CLOUD!
Pool is a number of physical servers that are maintained by a single organization or company to maintain the multiple requests that come in from various clients.
Clients are the systems and the requests are from the users who type URLs to open web pages/applications.
The pool of servers (example1, example2, example3, example4, example5) that have been mapped to a particular URL eg., http://www.example.com helps balancing the load/traffic enabling unbroken services to the client.
