Cloud computing is a networking concept where several remote servers connect in order to share a single repository while at the same time facilitating the online access to computer services and resources. In simpler terms, the networking of virtual servers in a data center is what forms a cloud.
Defining the types of clouds
In essence, there are three types of clouds including private clouds, public clouds and hybrid clouds. With public clouds, any one can gain access to the shared infrastructure over an internet connection as long as he or she pays the necessary connection fee. Private clouds on the other hand are very much similar to public clouds but serve specific enterprises or institutions over a secure firewalled connection. Hybrid clouds combine the attributes of the aforementioned clouds. They serve both purposes as the private and public clouds.
When it comes to cloud computing resources such as software, printers and information are accessible to cloud clients and other devices on demand, thereby greatly reducing the costs of purchasing standalone software and other peripherals.
Using the cloud practically
How to use the cloud depends on your needs and the type of service model you intend to utilize. Four types of service models exist including Infrastructure as a Service, Platform as a Service, Software as a Service and Unified Communications as a Service.
Infrastructure as a Service offers users virtual machines for networking, data storage, disk image libraries, IP addresses, firewalls and load balancers among many others. They offer physical resources for cloud clients on a pay as you go basis.
Platform as a Service offers clients a computing platform where they can carry out their activities. The platforms include databases, programming execution environments, operating systems and web servers. This service is popular among software developers
Software as a Service involves providing clients access to application software and databases. You do not have to install the software onto you machine as you can gain access to application software on the remote virtual servers.
Unified Communications as a Service entails offering communication services via devices such as cell phones. Services include video conference, webinars, IP telephony and bulk messaging services.
Free cloud hosting or paid cloud hosting – Why go for paid cloud hosting?
The advantages of paid cloud hosting surpass the minor cons.
- With paid cloud hosting, you are sure to get reliable round the clock customer support. The staff at most of these hosting companies is always willing to offer technical support in the event of any problems.
- Your data will always be secure considering the fact that hosting companies employ high-tech security strategies. In addition, they provide multi-tenancy services whereby your data is stored separately.
- Cloud hosting does not require any form of technical training as the hosting company will provide all the services that you need. All you have to know is how to gain access and retrieve data whenever you need it.
