Cloud computing

Cloud computing is an information technology that develops to delivery of computing services such as storage, database, networking, software, analytics and much more over the internet. In other words cloud computing is a delivery of hosted services over the internet. We all are using cloud computing in everyday life activities such as Banking, Email, Media Streaming, and eCommerce all use the Cloud but without knowing it.

Clouds can divide as public cloud, private cloud and hybrid cloud based on cloud computing resources. Public cloud would be provided totally by outside vendor. Amazon, Microsoft companies are some examples for public cloud providers. A private cloud refers to cloud computing resources used by a single organization or business. Hybrid cloud combines both public and private clouds and it gives greater flexibility and more deployment options to the business. Most cloud computing services can categorized under three main categories. Identify differences of these three categories makes it easier to achieve our goals easily.

1. Infrastructure-as-a-service (IaaS) : In IaaS, we can rent IT structure like servers and virtual machines, networks, operating systems from a cloud provider.


2. Platform as a service (PaaS): In PaaS, cloud providers supply an on-demand environment for developing, testing, delivering and managing software applications for developers. Heroku, Amazon’s AWS Elastic Beanstalk, and Microsoft Azure Cloud services are some examples of PaaS providers.


3. Software as a service (SaaS): SaaS is a method for delivering software applications over the Internet, on demand and typically on a subscription basis. Apple iCloud, Gmail, Webmail mail, Dropbox all are examples for SaaS.

Apart from day to day cloud computing using we use cloud computing for creating new apps and services, host websites and blogs, analyze data for patterns and make predictions, deliver software on demand etc. Some of the top benefits of cloud computing are flexed, disaster recovery, security, competitiveness, low cost, speed, high productivity, good performance.
