What is Cloud Computing?
Cloud Computing is a term we often hear but only a few actually know what it means. You must have heard your friends saying their data is stored in the cloud and by the way it doesn’t mean actual clouds. Well, you must have guessed that by now, unless you were stranded in a desert! Since Cloud computing is here to stay and it actually is a big deal, let us help you understand what is Cloud Computing.
What is Cloud?
Basically, the ‘cloud’ is just a metaphor for various data networks which are located somewhere far away and can be accessed via internet. Doesn’t sound like your idea of a cloud? It certainly isn’t a ‘cloud’ in a literal sense. Despite its name, ‘cloud’ has nothing to do with traditional clouds and no, you will not lose your data in case of stormy weather. What is cloud computing then?
‘The cloud’ simply denotes vast and diverse networks which might not be accessible to us physically but can still affect us. In cloud computing, the servers, fiber-optic cables and software engineers may be miles away from you but an interaction is possible. In terms of IT, it is a distinct IT environment designed to remotely provision scalable and measured IT resources.
Version of Cloud
Several varieties of cloud based computing services are present and users have plenty of choices when it comes to using a cloud based service suitable for their IT needs. The two most popular versions of cloud computing are Software-as-a-service (SaaS) and Infrastructure-as-a-service (Iaas). With SaaS, the cloud service provider hosts your data and applications on its servers and storage systems. You will need a web browser to gain access to the same. In IaaS, the service provider offers physical servers, virtual machines, switching, and storage and connectivity resources.
Types of cloud services
To an average computer user, one of the most basic cloud based services provided are cloud storage services. These include services such as remote data backup, file hosting and file sharing. All you have to do is simply sign up with a cloud storage service that will allot you certain free storage space usually 2-5 GB for hosting whatever data you want to save. There are also options to upgrade to more storage space. You can easily increase or decrease the usage of your services easily without physically interacting with the cloud computing infrastructure.
