DevOps Journey: Analyzing the impact of Components to Services (CFIA)

To ensure maximum uptime of services, there is a need to identify the components, resources, and configurations that enable the smooth operation of the service. IT systems and their configurations are growing in complexity as more services, components, and people are added into the mix.

To map out the relationships of services to other services or components, I use the Component Failure Impact Analysis (CFIA) matrix. In the event that a particular component (or configuration item) should fail, the CFIA Matrix helps me determine the potential impact on service delivery.

CFIA is a visual tabular view of services and their component items. It is part of a proactive Availability Management process. With this visual matrix, the IT decision makers of your organization can optimize the capability and capacity of the IT Infrastructure and resources. It can also identify high-risk components where the failure of those components will impact many inter-dependent services. It is a useful tool to justify upgrade or purchase of IT components.

How do you start with CFIA?

Given a service, identify the components that the service is dependent on. Determine the impact of your IT components on the service based on your pre-defined levels. Impact level can be 1) DOWNTIME(X), 2) WARNING(O) where the service is still operational but with reduced capability, or 3) NO IMPACT(Blank Space). Start with the basic services, then build up the list as you identify more components, services, and resources.

With the above illustration, it is easier to determine the relationships of the services, components, and resources.
