What is the Cloud?
Cloud computing is the delivery of on-demand computing resources (from applications to data centres) over the Internet on a pay-for-use basis
Cloud deployment models
When deploying new solutions Departments should select cloud models in the following order of priority.
Computing cloud resources are owned and operated by a third-party cloud service provider (CSP).
Public and private clouds are used with data and applications communicating between the two.
Computing cloud resources (that can be located on the premises or hosted by a third-party CSP) are dedicated to one organization and maintained on a private network.
A traditional IT environment for hosting legacy applications that cannot be deployed to a cloud environment
- Cost effectiveness: IT infrastructure is costly and labor intensive. Cloud offers an opportunity to offset these costs.
- High flexibility and scalability
- High accessibility from any device anytime
Cloud Computing Service Models
The National Institute of Standards and Technology defines 3 cloud service models:
IaaS – Infrastructure as a Service
IaaS offers services such as pay-as-you-go storage, networking, and virtualization.
IaaS gives users cloud-based alternatives to on-premise infrastructure, so businesses can avoid investing in expensive on-site resources.
PaaS – Platform as a Service
In PaaS, the vendor provides hardware and software tools over the internet, and people use these tools to develop applications.
SaaS – Software as a Service
Platforms make software available to users over the internet, usually for a monthly subscription fee.
GC Cloud adoption principles
The key principles developed are to ensure that the GC maximizes its benefit and at the same time complies with key data security requirements. The principles can be found in the Government of Canada Cloud Adoption Strategy.
Cloud Implementation Approach
TBS in collaboration with other departments had developed a 4 phases approach to implementing cloud. The diagram below depicts the developed approaches.
Considering Business Context
There's four factors to be considered when planning for cloud migration: Business, Information, Application, and technology while. For more information read the Government of Canada Right Cloud Selection Guidance.
