Elastic Stack vs Azure Monitor
Elastic Stack

The short version
- Only Azure Monitor has a free tier, so it costs nothing to try first.
- Each has a real cost: Elastic Stack self-managed deployment requires licensing based on node count and RAM usage; Azure Monitor billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
- They diverge on capability: Elastic Stack covers Full-text search, Azure Monitor covers Log collection.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Elastic Stack
- Self-managed deployment requires licensing based on node count and RAM usage
- Serverless option has pending features including traffic filtering and bring-your-own-key encryption
- Hosted deployment requires custom resource configuration for cluster management
- Pricing models differ significantly across Hosted, Serverless, and Self-managed options
Azure Monitor
- Billed per GB ingested across three separate log plans, Auxiliary, Basic and Analytics, so the plan chosen changes the rate as much as the volume does
- Only the first 5 GB a month of Analytics logs is free per billing account
- Retention beyond the base period is charged per GB per month, up to 2 years interactive and 12 years long term
- Log queries and search jobs are billed per GB scanned, so investigating an incident costs money
- Alert rules are billed per time series for metrics and by execution frequency for logs
- The pricing page shows placeholders rather than rates until a region and currency are chosen
