Cloud computing is the delivery of computing services—servers, storage, databases, networking, software, analytics and more—over the Internet (“the cloud”). Companies offering these computing services are called cloud providers and typically charge for cloud computing services based on usage, similar to how you are billed for water or electricity at home. You are already in cloud when you watch movies online, TV online, send emails, create documents online, store your pc and mobile data online and many more things being as an individual or working in organizations handling company’s datacenter as a couple of examples. Mobile companies also provide a partial cloud computing feature to store your contact details and other data on their datacenter so their subscribers can retrieve their data from anywhere on their mobile phones.
Cloud computing is deployed in three modules Private , Public and Hybrid .There are several vendors providing public cloud services , Microsoft , Amazon, Google are great players among those and are well known public cloud service providers for Infrastructure as a service (IaaS), Plateform as a service (PaaS), Software as a service (SaaS). Cloud computing is recommended for a tiny startups to global corporations, government agencies to non-profits—are embracing the technology for all sorts of reasons. Cloud computing has made the lives of IT professionals and developers very easy as they sit in coffee shop and plan for company’s annual, migrate and deploy their entire infra in cloud .
Cloud computing offers following features ;
• Create new apps and services
• Store, back up and recover data
• Host websites and blogs
• Stream audio and video
• Deliver software on demand
• Analyse data for patterns and make predictions
Cloud Computing offers considerable benefits in order to minimize asset cost where as increasing productivity which will bring SMEs to service providers
Cloud computing eliminates the capital expense of buying hardware and software and setting up and running on-site datacenters—the racks of servers, the round-the-clock electricity for power and cooling, the IT experts for managing the infrastructure. It adds up fast.2. Speed
Most cloud computing services are provided self service and on demand, so even vast amounts of computing resources can be provisioned in minutes, typically with just a few mouse clicks, giving businesses a lot of flexibility and taking the pressure off capacity planning.
3. Global scale
The benefits of cloud computing services include the ability to scale elastically. In cloud speak, that means delivering the right amount of IT resources—for example, more or less computing power, storage, bandwidth—right when its needed and from the right geographic location.
On-site datacenters typically require a lot of “racking and stacking”—hardware set up, software patching and other time-consuming IT management chores. Cloud computing removes the need for many of these tasks, so IT teams can spend time on achieving more important business goals.
The biggest cloud computing services run on a worldwide network of secure datacenters, which are regularly upgraded to the latest generation of fast and efficient computing hardware. This offers several benefits over a single corporate datacenter, including reduced network latency for applications and greater economies of scale.
Cloud computing makes data backup, disaster recovery and business continuity easier and less expensive, because data can be mirrored at multiple redundant sites on the cloud provider’s network.Back to top
