Cloud Computing

What is a Cloud Computing? Have you ever heard about it? Cloud Computing is a general term for the delivery of hosted services over the Internet.

When you are running applications that share photos to millions of mobile users or you’re supporting the critical operations of your business, a cloud service platform provides rapid access to flexible IT resources. With the help of cloud computing you don’t need to make large upfront investments in hardware and spend a lot of time on the heavy lifting of managing that hardware. Cloud computing supplies an easy way to access servers, storage, databases over the Internet. A cloud services platform such as Amazon Web Services maintains the network-connected hardware required for these application services.

You are probably using cloud computing every day but may be you don’t realize it. When you use an online service to send email, edit documents, watch movies or TV, play different games, etc., it’s likely that cloud computing is making it all possible. Cloud computing services are not so old but already a large variety of small and big companies, government agencies and are embracing the technology for all sorts of reasons. With cloud computing you can store and back up data, host websites and blogs, create new apps and services, analyze data for patterns, etc. Cloud computing is a big change from the traditional thoughts about IT resources. So why is cloud computing so popular? Most cloud computing services are provided self-services and the majority of computing resources can be provisioned in minutes. The biggest cloud computing services run on a worldwide network of secure data centers, which are regularly upgraded to the latest generation of fast and efficient com putting hardware. Cloud computing makes data backup and business continuity easier and less expensive.
Let’s see the three types of cloud computing:
Infrastructure-as-a-service (IaaS) – this is the most basic category of cloud computing services. With IaaS, you rent IT infrastructure-servers and virtual machines, network, storage and operating systems. Achieving high availability, business continuity and disaster recovery is expensive and need an amount of staff and technology. But with the right service level agreement in place, IaaS can reduce this cost and access applications and data as usual during a disaster or outage. Since you don’t have to first set up the infrastructure before you can develop and deliver apps, you can get them to users faster with IaaS.
Platform-as-a-service (PaaS) – it refers to cloud computing service that provides an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is created to make it easier for developers to quickly create web or mobile apps, without worrying about setting up the underlying infrastructure of services, network, storage and databases required for development.
Software-as-a-service (SaaS) – it is a way for delivering software applications over the Internet on demand and typically on a subscription basis. By SaaS, cloud providers host and manage the software application and underlying infrastructure, and handle any maintenance. Users connect to the application over the Internet, usually with a web browser on their phone or PC.
