The next wave of information technology jobs is in cloud computing, virtualization, data storage and storage area networks, and Microsoft and Cisco networks.
Cloud computing (CC) is a convenient, on-demand network with access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications and services) that releases data with minimal management effort or service provider interaction. “Moving to the cloud” also refers to an organization moving away from a traditional CAPEX model (i.e., buy the dedicated hardware and depreciate it over a period of time) to the OPEX model (i.e., use a shared cloud infrastructure and pay as you use it). End users access cloud-based applications through multiple platforms, including web browsers, mobile apps, personal computers and other smart devices, while data is stored on servers at a remote location.
Key enabling technologies include:
- Fast wide-area networks;
- Powerful, inexpensive server computers
- High-performance virtualization for commodity hardware.
