Save and Share with Cloud, Your Most Reliable Storage Drive!
In the world of IT technology, one thing has gained momentum extraordinarily i.e. “cloud computing”. The convergence of advanced analytics, social media, and mobility has come in affluence to facilitate the cloud computing. So, what is cloud computing? It is s a scalable service designed in a manner that it can be accessed on a higher bandwidth through the internet. Any computational work can be done on the basis of the demand routing it through a computer network. There are a number of cloud computing services available but choosing the one which suits to your needs is the essential job.
The industry of IT Technology spans over several platforms in terms of database and language, it may happen that the existing ones are outdated or they are looking forward to up gradation. There are various deployment models available under the umbrella of cloud computing such as:
- Public Cloud
- Private Cloud
- Community Cloud
- Hybrid cloud
- Combined Cloud
Each of these models has different services to offer. In the public cloud model, through web applications the resources are made available to the client. It is based on the standardized cloud computing model. Private Cloud is generally opted by the institutions where the security concerns are top most priority. There are cases where the information has been hacked even after maintaining strict vigilance. A robust IT infrastructure with proper safety nets can the save the information from leaking out. In the community cloud, a group of companies come forward to create a computing solution by sharing their infrastructure. The burden of the cost is shared equally by the number of participants in the community cloud. As the name suggests, hybrid cloud uses a combination of private as well as public storage clouds. This technology is very helpful in creating backup and archiving. Combined cloud consists of eases the transition to public cloud by using multiple external or internal service providers.
The complexity of the models of cloud computing varies from each other. But they can be broadly categorized as follows:
- Infrastructure as a service
- Software as a service
- Platform as a service
Infrastructure as a service or IaaS in short, offers cloud servers through API’s and dashboards. It is one of the most flexible computing models which comprise scalable system or computer resources with self provisioned network capabilities. One of the positive aspects of Iaas is that the maintenance cost is low; the clients have easy access to the server and it also offers high scalability storage.
Software as a service or SaaS is a software with high demand. A complete set of functional software is made available to the end users with the help of web services. The underlying cloud infrastructure includes operating systems, runtime environment, load balancers, servers, firewalls, etc. Applications from SaaS can be easily accessed through mobile also.
Platform as a service or (PaaS) is the platform where the development or the deployment of services takes place. PaaS provides an ideal environment where the server hardware, network infrastructure and server software are managed.
