Connecting the globe to a larger network to enable development was the thought behind Cloud Computing. What is cloud Computing? In the late sixties J.C.R. Licklider planned to integrate an intergalactic computer network and since then Cloud Computing has seen dynamic changes and evolutions. With time storing and accessing data moved from Desktop to Cloud conversion. What is Cloud conversion? Cloud is a metaphorical representation of a larger storing system which is nowhere in the sky but a gigantic server which hosts huge scale information in the internet that accepts and floats it out.
Cloud computing is amazing. It’s not about the kind of storage that you are familiar with on your PC or the large office server, network storage (NAS) hardware or a resident server. The thought behind cloud computing is accessing and synchronizing data and programs over the internet. This involves massive data processing which allows ‘the cloud ‘to be accessed from anywhere at any time on a pay for use basis.
The benefits of cloud computing offers increased storage, reduces cost and improves flexibility. However as experts has it, organizations should at first manage their own personal storage and then move on from Desktop to Cloud conversion. There are different types of Cloud Computing — infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS) and business process as a service (BPaaS). Of course to avail these services an (OSS) Operating System Services is needed which is responsible for deploying service and the other, (BSS) Business System Services which gives a ‘Go ahead’ by creating an invoice for the requested service and follows a flexible metrics for multiple users depending on the service provider. The Cloud Service Creator and Consumer both need to work on an interface and tool for the right cloud computing environment.
Software as a service (Saas) is extremely fast and generally starts rapidly with innovative business apps. The apps and data can be accessed from any computer that is connected. Even if the computer loses connection none of the data is lost. The service has than immense capacity for scalability and is flexible according to user needs.
Platform as a service (PaaS) provides a platform which supports building and delivering web-based applications. It develops apps and brings it to the market, arranges new web applications to cloud and reduces complexity.
Public Cloud is mostly operational on public networks and is extremely affordable providing rapid access. There is no requirement for hardware, software or supporting infrastructure as they are offered by the provider.
Private clouds are operated by single organisations and managed and by third party and are hosted both internally and externally. They do away with multi tenancy and have greater control on resources. It is a self served interface which gives liberty to the IT staff to make provision, assign and finally deliver resource. The management is company specific.
Hybrid cloud works on private cloud foundation but strategically integrates with public cloud services.
