Cloud Computing: An Introduction

If you work in a data center then you probably know that there are multiple servers for only one client. So you might think that this would make the link between them move faster, but sadly it does not. The term “Cloud Computing” became popular in 2007 as it had the potential to bring a halt to the busy days of network trafficking. The average time of work is greatly reduced due to the fact that this steady network is inclined to operate and converge on various machines, these shared databases can then be accessed with a application that is web based (E.g.: Business software’s, custom application as well as gaming interfaces). If you think that this might cost you a fortune then do not worry! For this to work all you need is a computer and an internet connection. We would recommend this to anyone that has a growing business since it is easy to use and the functions can be used at anytime, anywhere! 

There are 03 types of Cloud Service Models:

Infrastructure as a Service (IaaS):     
This model is mostly used by service providers, and is also a tool to assist other types of operations that the company is performing. IaaS also uses Firewalls, IP addresses, VLANs, etc. as a way of ensuring privacy. This service is quite a “Heavy-Duty” service since it is capable of supporting a large amount of Computers.

Examples of IaaS:  Google compute engine, Reliacloud, Rackspace, Amazon EC2, linode, HP cloud, Azure Service Platform, etc.

Software as a Service (SaaS):
This provides direct access to databases and any other software that might be linked. Since recently SaaS has become known for its hand in both web services and software oriented services (SOA). In most cases SaaS provides the same software for every user and therefore the group effort is at a high level.

Examples of SaaS: Marketo, Lotus, Casengo, Petrosoft, Webfilings, Salesforce.com, Onlive, GT nexus     

Platform as a Service (PaaS):
In this service the client extracts tools from the provider in order to create software’s suitable for the process. Since the service provider gives you everything from the network to storage all you have to handle is the software and the configuration settings!

Examples of PaaS: Mendix, Cloud foundry, Appscale, Beanstalk, Jelastic, etc

This technology is also being used for drug recovery! In 2012 a group of scientists struggled to identify potential levels of toxicity in modern drugs. It was a difficult and expensive task to complete since there was way too much information to analyze and the scientists could not get a hold of a super computer to perform this task; however with the help of Cloud Computing they were able to identify the toxic side effects of the modern drugs.

Logging systems is the software that is responsible for the level of security of an enterprise; it restricts log-ins to administrators only, thereby reducing the risk of an attack. If there is an attack the system should be reconfigured. The administrators can trace back data on an attempt to obtain the lost information. This prevents any further data transfers on to the wrong hands and you have a completely safe network!

If you have a business that is gradually growing into a large scale company then we recommend that you consider getting this system! Not only will it save you valuable time, it will also save a large amount of money!

If you already have Could Computing in your company then let us know if it was a good investment. As usual we would love to know what you, our readers, think of this system and if you would recommend it to anyone!
