Accessing your desired files sitting anywhere, anytime just by having a secure internet connection. Cloud computing; The ideal way to deliver enterprise applications through the pubic cloud model. e.g Amazon Web Services (AWS), Salesforce’s CRM System, and Microsoft Azure.
In layman’s terms, Cloud Computing is the delivery of computing services – such as storage databases, networking software, analytics, and intelligence – over the internet. The basic and the most important aim of Cloud Computing is to bypass traditional practices. As in old times, we have to store data in our hard drives or we needed a flash drive or portable ones to access data. But what if we have a meeting and we forget our drive at home. We cant access data but now with cloud computing we can. From any part of the world through the internet.
And make better use of investments than in new hardware or software. With the world growing towards virtual systems. Cloud computing is something like you just has to create an account on desired service providers and start using it by uploading documents, pictures, software anything you want. Then you can access it by just login with your credentials from any part of the world.
Benefits of Cloud computing:
Considered to be the next big thing, three distinct characteristics differentiate cloud computing from traditional web hosting:
- Sold on Demand – It’s no more about predicting the storage or services you’ll need in the future. Instead, it’s about what it is today. A user may have as much or as little of a service depending upon the need at the given time with the Service being fully managed by the provider. This makes it cost-effective and network efficient.
- Public or Private – Available to anyone or everyone or explicitly designed as per your requirements.
A public cloud is meant to sell services to anyone over the World Wide Web such as Amazon Web Services. On the other hand, the private cloud is a proprietary network. Limited to a specific number of people depends on their requirements.
- Storage – No more, hard drives, it’s all about third-party servers now. The service is location free you can access your data from anywhere by just accessing your account within seconds. There is no need to travel or to reach any specific place for accessing your data.
3 Major Service Models:
Service models of Cloud Computing also known as ” Cloud Computing Stack ” because they are built on each other.
- Infrastructure as a Service (IaaS): The lowest level cloud service paradigm and yet the most important. This works by providing pre-configured hardware resources to customers through a virtual network. Unlike the rest of the two, it doesn’t include applications, or operating systems rather enables access to infrastructure to support specific software. e.g, Gmail, Salesforce & Google Docs
- Platform as a Service (PaaS): Also known as “middleware”, which falls between IaaS and SaaS. Aiming to provide a platform for users to manage applications. It helps organizations eliminate the need to build infrastructures. Traditionally used to develop applications. e.g Amazon Web Service, Force.com & AppEngine.
- Software as a Service (SaaS): As the “on-demand software”, SaaS is a software licensing and delivery model where the complete and fully functional product is delivered to users over the web on a subscription basis. e.g Rackspace.com & Go Grid.
