🤯 Why Traditional Data Architectures Struggle
As organizations scale, central data teams become bottlenecks. Analysts wait weeks for access. Engineers drown in requests. And governance? Often an afterthought.
That’s where Data Mesh and Data Fabric come in — two decentralized paradigms, each attacking the problem differently.
🌐 What is Data Mesh?
Coined by Zhamak Dehghani, Data Mesh applies product thinking to data.
-
Key Principles:
- Domain Ownership: Each business domain owns its data as a product
- Data as a Product: APIs, SLAs, discoverability — just like software
- Self-Serve Platform: Infra enables domains to operate independently
- Federated Governance: Standards enforced without central bottlenecks
🧠 Think of it like this:
“Let your marketing, sales, and ops teams build, own, and share their own data pipelines — without waiting on the central data team.”
🧵 What is Data Fabric?
Data Fabric is an architecture that uses metadata and automation to unify data across sources — without physically moving or copying it.
-
Key Pillars:
- Active Metadata: lineage, quality, usage, and classification in real-time
- Data Virtualization: query across systems as if they were one
- Orchestration & Governance: embedded into the platform itself
- AI/ML Assistants: automate transformation and detection of anomalies
🔍 Think of it like this:
“Your data stays where it is — but your platform makes it feel integrated, clean, and governed.”
🆚 Mesh vs Fabric – Conceptual Differences
| Feature | Data Mesh | Data Fabric |
|---|---|---|
| Focus | Organization / People | Technology / Platform |
| Governance Style | Federated (human + process) | Automated (metadata-driven) |
| Architecture | Domain-based ownership | Unified, virtualized fabric |
| Ideal For | Complex orgs with domain teams | Enterprises with many tech silos |
| Examples | Snowflake Shares, dbt + Terraform | Azure Purview, Informatica, Talend |
☁️ Real World Examples
🧊 Snowflake
- Use Secure Data Sharing to expose a domain’s curated dataset to others — no copies needed.
- Combine with Snowgrid for cross-region/global mesh setup.
🟥 Redshift
- Use RA3 nodes for domain-level compute isolation.
- Define Redshift data sharing or Spectrum + Glue Catalog for federated access.
🔵 Azure
- Combine Azure Synapse, Data Factory, and Purview:
- Synapse = warehouse & Spark
- Data Factory = pipelines
- Purview = governance/fabric layer
