- 8. SMELL :: CONFIGURATION DRIFT • Any change outside a baseline configuration is considered a configuration drift. • Could be an accidental or incidental or intentional. • Early identification will minimize impact and reduce the risks around business continuity.
- 9. PRESCRIPTION :: AUTOMATED CONFIGURATION
- 10. SMELL :: SYSTEMS ENTROPY As a system is modified, its disorder, or entropy, always increases. • Similar to theories in software development, a system that is used will be modified. • When a system is modified, its complexity will increase, provided that one is not actively working to reduce complexity.
- 11. PRESCRIPTION :: SEPARATION OF CONCERNS How can I build my web hosting business? How can I manage my customer relationships? Data How can I run my company's IT department? Center How can I collaborate across the enterprise? How can I view my corporate sales data? Software How do I store & retrieve my inventory data? How do I deploy my web services? Platform How do I get the most of my IT and Infrastructure personnel resources?
- 12. SMELL :: STAFFING ATROPHY “Atrophy is the partial or complete wasting away of a part of the body. Causes include lack of exercise and/or use”
- 13. PRESCRIPTION :: DRILL, BABY. DRILL.
- 14. SMELL :: GOLD IMAGE
- 15. PRESCRIPTION :: USE CONTINUOUS PROVISIONING Consistent, repeatable builds encourage fast deployment and consistently identical systems without the burden of managing images A repeatable build improves product quality, reduces the mundane tasks and minimizes dependencies on key people. build cycle Software packages
- 16. SMELL :: TEETERING STACK
- 17. PRESCRIPTION :: CONTAINER PARTITIONING Virtualization can reduce cost while also improving flexibility… Cluster multiple physical servers to gain failover capabilities Share resources across physical servers source: “Automated failover and recovery of virtualized guests in Advanced Platform”, Rob Kenna, Redhat Magazine
