A data warehouse is a centralized system used for storing, reporting, and analyzing large volumes of structured and semi-structured data. It is a core component of Business Intelligence (BI) that helps organizations make data-driven decisions.
Modern data warehouses have moved from on-premise infrastructure to cloud-based platforms, reducing setup cost, improving scalability, and simplifying maintenance.
A data warehouse service that can be optimized for a specific use-case and fully managed by AWS, when it comes to analyzing huge volumes of data. It has a column storage model to facilitate the query of structured information.
Key Features:
Columnar storage for fast analytical queries
MPP (Massively Parallel Processing) architecture
Auto-scaling and pay-as-you-use pricing
Native integration with AWS ecosystem (S3, Glue, Athena)
2. Microsoft Azure Synapse Analytics
A suite of data warehouse programs such as Azure Synapse Analytics that takes a cloud computing system approach. It helps to build, deploy and manage data warehousing solutions with machine learning capabilities within its architecture.
Key Features:
Distributed query processing

3. Google BigQuery
A tool for analyzing Big Data that is specifically for data warehouses without having to manage the servers. It is pay-as-you-go and boasts faster query operations with the inclusion of SQL support.
Key Features:
BigQuery is an intelligent database that facilitates processing of large dataset for insights. It reduces the need for human intervention in the server and can automatically increase resources if the queries requested are beyond the limit of available resources and can facilitate large-scale data warehousing for big data analytics.
BigQuery is a Google’s pay-per-use Cloud Storage solution that charges you only when you use their services. This makes it the most cost-effective for testing different volumes of data.
Google Cloud services provide additional features like Cloud AI Platform for BigQuery when using the BigQuery service to perform some statistical analysis or to use advanced analytics capabilities to derive new insights from data.
