What does Cloud computing mean?
Cloud computing means that infrastructure, applications and business processes can be delivered to you as a service, over the Internet.
Though the concept has been around for the last few decades under various different names, the most recent being Software as a Service (SaaS), it is the recent need to share in order to be productive that has seen cloud computing become an acceptable concept.
Some ways you may know it in your everyday life would be things like online file sharing services like Google Docs, mobile push and sync services and even email.
How does the ‘cloud’ work?
Most websites and server based applications run on particular computers or servers. What differentiates the cloud from the way those are set up is that the cloud utilizes the resources from the computers as a collective virtual computer, where the applications can run independently from particular computer or server configurations.
To understand how cloud computing works; imagine that the cloud consists of layers – back end layers and front end layers. The front end layers are the one you can see and interact with. For example, accessing your face book account or your G mail account. The back end consists of the hardware and the software architecture that fuels the interface you see on the front end.
Cloud computing allows for a lot of flexibility. Depending on the demand, you can increase how much of the cloud resources you use without the need for assigning specific hardware for the job, or reduce the amount of resources assigned to you when they are not necessary.
Some Benefits of Cloud Computing
• Improves accessibility.
• Ability to monitor projects more effectively.
• Reduces capital costs.
• Streamlines processes.
• Reduces spending on technology infrastructure.
• Achieves economies of scale.
• Minimizes licensing of new software.
• Improves flexibility.
Future of Cloud Computing
The Cloud has the potential to become the preferred mechanism for software delivery, bringing more choices to organisations when selecting an application provider, and resulting in fewer reasons to maintain their own applications on-premise.
We will see more and more organizations seeking alternatives to on premise deployments. Cloud adoption will increase dramatically and when moving to the cloud, businesses will need to think carefully about how they will ensure that cloud providers can meet promised service level agreements (SLAs).
We will also see a higher rate of adoption of smart phones and tablets within the workforce in 2013. Gartner predicts that by the end of 2013, mobile phones will overtake PCs as the most common web access device worldwide. Gartner also predicts that the personal cloud will replace the PC as the centre of users’ digital lives by 2014.
Visiongains analysis indicates that the total value of the global cloud computing services market revenues reach $35.6 billion by the end of 2013; driven by increasing adoption of cloud services from the enterprise side.
The I.T. industry has always been a rapidly changing market and with the creation of the Internet this speed has only increased due to inter connectivity. The cloud will add on another level to this by making inter connectivity a personal possibility rather than simply a social tool. By allowing you to connect to your own online data as and when you please- this will have a big impact on not only how you use this data, but how you will allow others to share this data also.
