Cloud operations · Assessing change impact on services

Unclear change impact puts cloud services at risk

A software company with 3,100 employees runs more than 250 cloud services, and around 230 changes a day cause outages.

Starting point

A software company with 3,100 employees runs more than 250 cloud services across several platforms. Around 230 changes are logged in the ITSM system every working day, ranging from small configuration tweaks to larger platform updates. About 40 percent of these changes affect central platform components used by several product teams. Documentation of the dependencies is scattered across the CMDB, wikis and architecture diagrams. Service owners and platform teams spend several hours a day identifying the services affected by planned changes and estimating the risks.

The challenge

The change processes are formally established, but assessing the impact in practice remains tedious. For each of the roughly 230 daily changes, platform teams and service owners have to check which services, pipelines and integrations are affected. Dependencies are often only partly maintained in the CMDB, and further clues sit in tickets, runbooks or architecture diagrams. As a result, risks are underestimated, the wrong maintenance windows are chosen or affected teams are informed too late. Unplanned service interruptions and rollbacks after changes cost time, cause night shifts and undermine trust in the change process.

Typical symptoms in the company

“For many changes, we don’t know which services are really affected”

“We often only inform service owners once problems already show up in monitoring”

“We spend too much time reading old tickets and runbooks for impact analyses”

“We have too many rollbacks because hidden dependencies only surface in production”

Why this remained unsolved

The problem had been known for a long time but was accepted as an unavoidable complexity of cloud operations. A complete and always up-to-date CMDB seemed unrealistic, and manual impact analyses were considered necessary effort. Classic automation failed because dependencies are described in free-text tickets, wikis and diagrams. A dedicated CMDB modernization project was postponed for lack of resources. So the effort in the change advisory boards stayed high, while unplanned service interruptions were accepted as an operational risk.

CMDB cleanup project

A one-off CMDB cleanup project improved the data in the short term, but could not cover ongoing maintenance or free-text dependencies.

Checklists for the CAB

Standardized checklists in the change advisory board helped with documentation, but did not reduce the research effort in tickets and wikis.

Our solution

An agentic workflow now supports the impact analysis of changes across several systems. For every new or modified change record, the workflow automatically gathers context from ITSM tickets, the CMDB, monitoring, wikis and architecture diagrams. Generative AI analyzes this information, identifies affected services, typical failure patterns and relevant runbooks, and produces a structured impact report. The report is attached to the change in the ITSM system, flags critical services, suggests communication paths and points to known risks. Before the CAB, platform teams and service owners get a consistent basis for decisions and can plan maintenance windows, tests and escalation paths in a targeted way.

Where generative AI comes in

Generative AI reads change descriptions, historical tickets, runbooks and architecture texts, summarizes dependencies in clear impact reports and suggests affected services and communication paths. It combines unstructured text, different writing styles and partly outdated documentation, and flags uncertainties transparently.

Building blocks
  • Automated gathering of context from the ITSM system, CMDB, monitoring, wikis and architecture diagrams for every new or modified change
  • Generative analysis of the change description, history and dependencies to identify affected services, pipelines and integrations, with an impact report
  • Integration of the impact report into the ITSM system, highlighting critical services, suggesting communication and linking relevant runbooks
  • Feedback loop for platform teams and service owners to review suggestions and gradually improve the quality of the impact analyses
How it works

How the impact workflow runs

  1. Gather context

    When a change is created or modified, the workflow automatically gathers context from ITSM, the CMDB, monitoring, wikis and architecture diagrams.

  2. Analyze impact

    Generative AI analyzes descriptions, history and dependencies, identifies affected services and known risks, and structures the results.

  3. Deliver the report

    The impact report is stored on the ITSM change, flags critical services, links runbooks and suggests communication paths.

  4. Collect feedback

    Platform teams and service owners review the report, add notes and mark corrections that feed into future analyses.

  5. Evaluate metrics

    Regular evaluations of rollbacks, outages and processing times show how the workflow affects the change process.

Running costs

Running the workflow covers platform operations, model usage and maintaining the integrations with ITSM, the CMDB and knowledge sources.

Limitation

The solution depends heavily on the quality of the existing documentation. In areas with outdated CMDB entries or missing runbooks, impact analyses remain uncertain and still require manual review by experienced platform teams.

Integration and operations

Connected systems

The workflow is integrated into the existing ITSM system, has read access to the CMDB, monitoring platform, wikis and architecture repositories, and writes impact reports as additional change artifacts.

Operations

The solution runs in the company’s existing cloud environment, separated from production workloads, with restricted access to the ITSM and knowledge systems it needs.

Compliance

Access to change data and documentation is logged, role permissions from ITSM and knowledge systems are respected, and no production customer data is processed outside the company environment.

Labeling

Impact reports state that they were generated automatically and must be reviewed by experts before approvals.

Accountability

The reports serve as decision support but do not replace the responsibility of change managers and service owners for approvals and risk assessments.

Escalation path

If impact assessments conflict or a change is critical, change managers can escalate the report to trigger a manual architecture review.

Traceability

Every impact report references the sources used, such as tickets, CMDB entries and runbooks, so platform teams can trace how the assessment was reached.

Roles in operation

Platform teams own the operation and further development of the workflow, change managers use impact reports in the CAB, service owners provide feedback, and IT governance monitors metrics and policy compliance.

Transferability

The agentic workflow for change impact analysis can be transferred to other environments where many changes come with scattered dependencies. Wherever changes are documented in a ticketing system, dependencies are described in free-text or semi-structured sources and several teams are affected, generative AI can prepare impact reports. Clear governance matters: which changes are analyzed automatically, and how feedback flows into improving the suggestions.
