Learning in the Cloud
Cloud computing addresses these issues by providing widely accessible, on-demand, self-service tools and applications — all via pooled resources, which cuts down on cost.
Demystifying the Cloud
So what exactly is cloud computing? According to the National Institute of Standards and Technology (NIST), cloud computing is defined as “a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”
To simplify it further, cloud computing typically refers to one of three service models: software as a service (SaaS), platform as a service (PaaS) and infrastructure as a service (IaaS). A helpful way to break it down is to think of it as a pyramid. On the top, you have SaaS, which refers to applications hosted entirely on the Internet — no software is installed on the desktop computer. Gmail, Google’s e-mail program, is a prime example. Most cloud vendors are offering this kind of service.
PaaS would come next. It refers to a virtual environment that allows IT developers to develop applications in the cloud as well as provides a platform for cloud programs to integrate.
At the bottom of the pyramid would be IaaS, possibly the most nebulous of all the cloud services. IaaS refers to a basic outsourcing model whereby a third-party service provider owns the equipment used to support operations such as storage, hardware, servers and networking and is responsible for running and maintaining them.
Taken as a whole, these three services allow organizations to create, run and store content online using shared providers, cutting down on costs and providing pay-for-use flexibility.
