The cloud’ is internet-based computing. It replaces your on-site IT systems –servers, storage, security, applications and more – with remotely hosted resources.
There are three broad categories of cloud computing. The first is Software-as-a-Service (SaaS), which represents the largest cloud market. With SaaS, your applications are managed via a third-party vendor (like Salesforce.com), eliminating the need to install and run applications on individual devices.
The second cloud model is Platform-as-a-Service (PaaS). It’s a step up from SaaS, as it offers a framework for developing and customizing your applications.
The third model is the most advanced, called Infrastructure-as-a-Service (IaaS). This is a self-service model for accessing, monitoring and managing remote data center infrastructures.
Regardless of which model you choose, instead of installing apps and desktops on each and every personal computer, you simply (and securely) deliver them from the cloud to any device.
That’s a big deal because it means all of the heavy lifting (like storage and security) is done for you.
The cloud includes remote access to all of your files, apps and data. And cloud services are deployed quickly, and are easily consumed through a monthly subscription model.
