The document discusses DevOps toolchains which integrate development and operations tools to improve software delivery. It provides examples of toolchains for activities like continuous integration, deployment, testing, and monitoring. The key benefits are cited as increased efficiency, consistency, safety, and visibility across the development and operations processes. The document recommends auditing current practices, agreeing on a vision, and gradually adopting tools to achieve DevOps.

Apps: More Important / More Complex
More frequent changes
Lower tolerance for outages
More complex applications
More complex deployments
Need: Fix the Dev to Ops hand-off for speed /
reliability, and deliver better visibility into production
performance.

Example impact on tools: Issue Trackers
Shared Tools: Within a project, have a common backlog for
development and infrastructure tasks.
Automation: Make sure you have APIs available to
automatically create / migrate tickets based on tests,
monitoring, deployments.

Where does this get us?
Efficiency
Less manual effort
We avoid rework
Information is easier to find
Less dependence on tribal knowledge

19. © 2013 IBM Corporation
Where does this get us?
Consistency
Tasks required to deliver tracked in one place
CI and “official builds” unified
Same deployment tool for all environments
Same infrastructure tool in all environments

1. Ensure at least “ok” build
2. Work on the deployment / delivery tool chain
3. Attach feedback mechanisms opportunistically
