Does Nexus replace any of these systems?

No. Each system keeps its own records. Nexus runs the process between them and records each decision.

What if a step is not covered by a pre-built action?

It runs through an API, protocol or database call, or as Rules + Code in Python, Bash, Go, Java, .NET, PHP, PowerShell or JavaScript/TypeScript, with the same approvals and audit.

Critical infrastructure use case · Amazon Web Services + Snowflake + ServiceNow

Cloud event to analytics workflow

Cloud telemetry is either analysed or acted on, rarely both. Cloud events are enriched, loaded for analysis and escalated when thresholds are crossed.

How it starts: AWS CloudWatch, CloudWatch Events, S3, SNS or SQS starts the run.

Step by step

How the process runs

01
Event
The AWS event arrives. EC2, S3, IAM and Lambda actions add context.
02
Load
Snowflake data loading actions load the enriched event. Tasks update tables and views.
03
Threshold
Rules + Code checks thresholds and opens a ServiceNow incident or ticket if crossed.
04
Remediate
Any AWS remediation waits for approval.

Control

Human decision and exception path

Human decision

An operations engineer approves any remediation before it runs in AWS.

Exception path

Duplicate events are grouped.
Failed loads are retried.
Remediation failures reopen the incident.

Evidence

What gets audited

Event.
Enrichment.
Load result.
Incident, approval and remediation output.

Nexus runs on premises, in private or sovereign cloud, or air-gapped. Credentials stay in the vault, roles decide who can approve, and the execution record stays inside your deployment boundary.
