Definition
• Infrastructure as code (IaC) is the process of managing and
provisioning computer data centers through machine-readable
definition files, rather than physical hardware configuration or
interactive configuration tools.[1] The IT infrastructure managed by this
comprises both physical equipment such as bare-metal servers as
well as virtual machines and associated configuration resources. The
definitions may be in a version control system. It can use either scripts
or declarative definitions, rather than manual processes, but the term
is more often used to promote declarative approaches.

What are “large scale organizations” ?
• Many environments/stages between DEV and PROD (typical 3-5)
• Many types of architectures, applications and infrastructure on hypbrid/multi cloud envs.
• applications x environments x delivery frequency = {a large 6 – 7 figure number}
• Growing complexity towards PROD
• Example: 4000 Applications on ca. 20K Servers , everything from old Mainframe up to latest Cloud
and Container Services and everything in between, different release cadences from CI/CD over
daily to quarterly PROD deployments
• Also: Loosely coupled - but dependencies are still present - also between „new“ and „old“ world
systems

What challanges did we observe ?
Security: How can I control who can create or modify the infrastructure of each environment? How do
we manage secrets ?
Auditability: WHO made that change, WHEN, HOW and WHY?
Configuration Management: How can I manage the specific configurations of each environment ?
Organizational Scalability: How can I manage the hundreds or thousands of scripts I have in my
organization ?
Dependencies: How can I manage dependencies between organization-wide change requests in
different tools ?
Integrity: Why do I have to use two completely different approaches to provision infrastructure and
deploy software on that infrastructure? How do I integrate both flows as if they were one?
Compliance: How can I guarantee that the corporate process defined for dealing with supply requests
is followed, guaranteeing that all necessary approvals are obtained or that the CMDB is always kept
up-to-date?
Visibility: How can I get immediate information on the status of a provisioning request ?

What is the issue with siloed organizations ?
• Reduce defects by 15%
• Improve UX interface
• Add 10 high-priority features
• Improve app security
• Decrease release time by 50%
✘ Siloed teams for Infra, App Dev,
Deployment and disconnected
hand-offs & disparate tools
✘ Development has limited
visibility into business KPIs
✘ Business has limited visibility
into development & delivery KPIs
✘ No awareness of application

Hypothesis
• Questions to clearify
• Compliance, Auditability
• IT SM Integration
• Central Configuration and Paramer Management
• Integrate Secret Management
• Organizational Scalability
• Business and technical dependencies beetwen Infra, Apps, Products
• Visibility
