Azure Data Factory (ADF) is a cloud-based data integration service that allows you to create data-driven workflows for orchestrating and automating data movement and transformation. It enables the creation of ETL/ELT processes that can ingest data from disparate data stores, transform it, and publish it to data stores for analytics.

• Cloud-based ETL/ELT service
• Orchestrates data movement and transformation
• Connects to diverse data sources (on-premises, cloud)
• Supports scheduled, event-driven, and on-demand pipelines

Memory trick: Data Factory builds the pipeline to Synapse.

A cloud search service that provides a rich search experience to applications by adding AI-powered cloud search capabilities. It supports full-text search, faceted navigation, geospatial search, and more, and can ingest data from various Azure data sources.

• Provides AI-powered full-text search and indexing
• Supports flexible querying and faceted navigation
• Integrates with Azure data sources (Blob, SQL, Cosmos DB, etc.)
• Scalable for large volumes of searchable content

Memory trick: Cognitive Search indexes your blobs so users can find them, smart!

The Azure Blob Storage Archive tier offers the lowest storage costs for infrequently accessed data with flexible latency requirements. An immutability policy ensures that data stored in a blob container cannot be modified or deleted for a specified period, crucial for regulatory compliance.

• Archive tier: Lowest cost, highest latency for access (hours)
• Immutability policy: Prevents deletion or modification for a defined retention period
• Ideal for compliance, auditing, and long-term backups
• Data is 'write once, read many' (WORM) compliant

Memory trick: Archive blobs with immutability, records frozen in time.
