Results of Low Performance


Silos exist between development & operations. Differing objectives and

incentives Both sides “throw it over

the wall”

Software deployments are nail-biting events Firefighting & heroics Buy more infrastructure!

Infrequent deployments, delayed feedback loop & time to value Poor visibility Undefined goals

DevOps: Focus on Outcomes Eliminate Constraints, Increase throughput by:

Reducing excess inventory buffers and work Minimize Deployment-Related Downtime Reduce Defect Resolution Time (MTTR) Better Collaboration Between Silos Shared Organizational Goals for Improvement

Results should be faster delivery, better quality Lower IT infrastructure cost is a side effect, not a

goal


Blame QA?

If other industries get this concept, why doesn’t IT?

Applying Lean Principles


Agile Development vs. Theory of Constraints

1. Agile Dev(faster iteration)

2. Access Environment(no change)

3. Same Output(agile illusion)

Apply “Just in Time” environments to be triggered by dev teams on demand.

Control WIP until excess work is cleared.

DevOps Perspective


“The first bottleneck in a rapid DevOps flow is environment creation. You need one click self-service environments for everyone.”

“Every high performing company we studied had found a way to make production like environments available to developers.”

The Skytap Difference


Built for Complex environments------------------------------------------------------------

• Server/cluster configurations, appliances/load balancers, advanced networks and IP/domain settings – Not just a bunch of VMs

• Pre-loaded with data and virtual assets

• Connect intra-environment workflows via ICNR

Built for agile dev/test Collaboration------------------------------------------------------------

• Copy environments across global cloud regions for “follow the sun” projects

• On-demand, elastic resources avoid conflicts over labs

• Easily freeze and share current state with other teams for earlier defect resolution

Built for IT/Ops Control------------------------------------------------------------

• Maintain visibility and control costs

• Deliver self-service provisioning

• Set permissions, quotas & policies by user, department, project

• Automate lab provisioning and suspension of idle resources

• Universal access to labs with published URLs

Takeaways Organizational alignment trumps technology

changes! (People, Process, Technology… in that order)

Don’t get trapped in all-or-nothing approaches Pilot a customer-facing program where innovation

and time-to-market improvements have upside Measure IT cost savings on a per-cycle or per-

environment basis, as usage patterns in devtest will naturally increase

Champion the change, call it by any other name
