Architecture Cost Strategy

Enterprise architecture is not just about moving data; it is about managing the Total Cost of Ownership (TCO). I design scalable cloud environments that maximize performance while rigorously controlling operational expenditure.

On-Premises (CapEx)

  • High upfront Capital Expenditure for servers, cooling, and real estate.
  • Hardware depreciation over 3-5 years, requiring costly refresh cycles.
  • Over-provisioning is mandatory to handle peak loads, leaving costly compute sitting idle 80% of the time.

Cloud Migration (OpEx)

  • Zero upfront capital. Shift to agile Operational Expenditure (Pay-as-you-go).
  • Elastic scalability allows compute engines to auto-pause during non-business hours, drastically reducing TCO.
  • Delegated maintenance: Security, patching, and hardware management are handled by Azure.

Azure Data Product Licensing Matrix

My approach to provisioning and optimizing resource costs across the Microsoft Data stack.

Microsoft Fabric

Unified compute billing. Instead of paying separately for pipelines, notebooks, and SQL, you provision a single compute capacity (e.g., F64) that is shared across all workloads. Pausable to save costs.

Billing Model: Capacity-Based (F-SKUs)

Azure Databricks

Billed on Databricks Units (DBUs) for the processing engine, plus the underlying Azure VM compute costs. Optimized via automated cluster termination and Spot Instances for non-critical ELT.

Billing Model: DBUs + VM Compute

Azure Synapse Analytics

Dedicated SQL Pools are billed hourly based on Data Warehouse Units (DWUs). Serverless SQL is highly cost-effective for exploratory analytics, billed strictly at ~$5 per Terabyte of data processed.

Billing Model: DWUs & Serverless TB

Azure Data Factory (ADF)

Micro-billing based on pipeline activity, execution time, and Data Integration Units (DIUs). Cost optimization focuses on reducing parallel copies and mapping data flows effectively.

Billing Model: Pay-Per-Execution & DIUs

Azure Data Lake (ADLS Gen2)

Billed by data volume at rest and Read/Write operations. Costs are aggressively managed by implementing Lifecycle Management policies to move stale data from 'Hot' to 'Cool' or 'Archive' tiers.

Billing Model: Storage Tiers & Transactions
