Cloud Computing

Cloud computing is the delivery of on-demand computing resources, everything from applications to data centers, over the Internet on a pay-for-use basis.


Cloud Computing Services

Software as a Service (SaaS)

Cloud-based applications or software as a service (SaaS), run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the Internet and usually a web browser. First, there’s no software to purchase, install, update or maintain, which is handled by the service providers. As well:

  • You can sign up and rapidly start using cloud apps
  • Apps and data are accessible from any connected computer
  • No data is lost if your computer breaks, as data is in the cloud
  • The service is able to dynamically scale to the usage needs of your organization

Platform as a Service (Paas)

Platform as a service provides a cloud-based environment with everything required to support the complete lifecycle of building and delivering web-based (cloud) applications, without the cost and complexity of buying and managing the underlying hardware, software, provisioning and hosting.

  • Develop applications and get to market faster
  • Deploy new web applications to the cloud in minutes
  • Reduce complexity with middleware as a service

Infastructure as a Service (IaaS)

Infrastructure as a service provides companies with computing resources including servers, networking, storage, and data center space on a pay-per-use basis.

  • Since you don't need to invest in your own hardware, IaaS is perfect for start-ups or businesses testing out a new idea
  • since the infrastructure scales on demand, it's great for workloads that fluctuate rapidly
  • Your business rents infrastructure from the cloud provider,
    and accesses that infrastructure over the Internet, in order to create or use applications


Hybrid Cloud

Evolving to a hybrid cloud strategy will allow companies to keep critical line of business applications and sensitive data in a traditional data center environment or private cloud, while also taking advantage of public cloud resources like SaaS for the latest applications and IaaS for elastic, economical virtual resources to scale.

The key factor for hybrid cloud success

The ability to efficiently and securely manage the combination of public and private cloud services as a single unified computing environment is the key capability to fully taking advantage of the cloud.
