Where does Release Management fall in the ITIL framework?
ITIL Service Transition process
What is a Release (ITIL Term)
A collection of authorized changes to an IT service i.e. A collection of hardware, software, documentation, processes or other components required to implement one or more approved changes to IT services. The contents of each release are managed, tested and deployed as a single entity.
What is a Release Unit (ITIL Term)
It describes the portion of a service or IT infrastructure that is normally released together according to the organization’s release policy.
What is a Release Package (ITIL Term)
A single release unit or a structured set of release units, including the associated user or support documentation that is required.
What is Change Management (ITIL Term)
Change management processes are used to deliver a finalized and tested change into a pre-production environment along with a set of tools and/or procedures for migrating the change into the live production environment
What is Build Management (ITIL Term)
The software, hardware and documentation that comprise a release unit should be assembled in a controlled manner to ensure a repeatable process. This should include automation where possible for its compilation and distribution, which for large organizations can significantly reduce the Total Cost of Ownership for the services involved
What is Release Management (ITIL Term)
Key technology for distributing the project/product to the consumer
What is Deployment (ITIL Term)
The activity responsible for movement of approved releases of hardware, software, documentation, process, etc. to test and move to production environments
What is DSL (ITIL Term)
The definitive Software Library (DSL) must hold a copy of all the software installed in the IT environment. This includes not just operating systems and applications, but also device drivers and any associated documentation. The DSL should contain the complete release history of each piece of software in order to provide the necessary version in the event that back-out plans should be implemented
What is DHS (ITIL Term)
The definitive Hardware Storage (DHS) contains spare parts for the CIs in the production environment. The assets stored must be included on the CMDB if the corresponding CIs are listed on it
What type of release classifications are there? (Name 3)
Major releases
Minor releases
Emergency releases
Name a couple of different Release Design Options
Big Bang option
Phased approach
Push and Pull
Automation vs Manual
What is a Big Bang Release option?
The new or changed service is deployed to all user areas in one operation
What is a phased approach in release management?
The service is deployed to a part of the user base initially, and then this operation is repeated for subsequent parts of the user base via a scheduled rollout plan
What is the difference between a Push and Pull approach in release management?
Push is where the service component is deployed from the center and pushed out to the target locations. (Both Big Bang and Phased approaches constitutes push
A pull approach is used for software releases where the software is made available in a central location but users are free to pull the software down to their own location at a time of their choosing
