Atlas problems — sound familiar?
- ▸ Atlas bill doubled in 6 months — Auto-scaling is on but not configured per-shard; M30 clusters that should be M10, M60 nodes carrying analytics that should be on Atlas Data Federation. Nobody's done the right-sizing audit since launch.
- ▸ Atlas Search retrieval surprisingly slow — Custom analyzers and Atlas Search index definitions tuned for the original schema; new fields added but never indexed in $search; latency degrading every release.
- ▸ Cross-region replication question — EU customers need data-residency but the cluster is single-region us-east; the migration to Atlas Global Cluster is operationally significant and your team hasn't done one before.

MongoDB Atlas Consulting, Migration & Optimization
MongoDB Atlas expertise: M-tier sizing, auto-scaling tuning, Atlas Search, Vector Search, Stream Processing, cross-region replication, Performance Advisor integration.
Atlas Coverage
Atlas-specific services we run
Cluster sizing & right-sizing
M-tier audit across all clusters; identify M30/M60 nodes carrying workloads that fit M20 or M10; configure auto-scaling per-shard. Typical outcome: 30-50% Atlas bill reduction.
Migration to Atlas
Self-hosted → Atlas via mongosync, live migration, or change-stream-based dual-write; we handle the IP-allowlist + Private Link + connection-string rotation gauntlet that derails most cutovers.
Atlas Search optimization
$search index definition review, custom analyzer audit, retrieval-vs-latency trade-off tuning. Includes Lucene-direct comparison if Atlas Search is mis-sized for the workload.
Atlas Vector Search
knnBeta / vector index sizing for embedding workloads, hybrid search (BM25 + vector), AVS chunking strategy for RAG pipelines.
Atlas Stream Processing
Stream processor pipeline design, source/sink integration (Kafka, Kinesis, Atlas Triggers); when to use vs CDC via Debezium.
Cross-region & Global Clusters
Multi-region replica-set topology design, write-region selection, read-preference tuning, Global Cluster zone definitions for data residency.
Atlas Data Federation
Decouple analytics from OLTP; federate to S3 / Atlas Online Archive; cost-effective for queries that don't need real-time MongoDB.
Atlas Online Archive
Cold-tier offload via timestamp/field rules; cost reduction for time-series and audit-log data while retaining queryability.
Engagement Shapes
Three Atlas engagement shapes
Atlas Audit
Right-sizing review across all clusters, Performance Advisor analysis, Atlas bill breakdown, optimization roadmap.
Atlas Migration
Self-hosted → Atlas or cross-region migration with risk-graded cutover plan, mongosync execution, post-cutover validation.
Atlas Managed
Ongoing Atlas operations — alert tuning, index reviews, capacity planning, version-upgrade coordination, Performance Advisor follow-through.
