Overview: Azure Synapse Analytics vs. Google BigQuery

Azure Synapse Analytics

Azure Synapse Analytics is an integrated analytics service combining enterprise data warehousing, big data analytics, and data integration. Synapse brings together big data and data warehousing in a single platform, enabling users to query both relational and non-relational data using SQL, Spark, and on-demand querying. Synapse’s tight integration with other Azure services, like Azure Data Lake, Azure Machine Learning, and Power BI, makes it a strong choice for enterprises already using Microsoft technologies.

Google BigQuery

Google BigQuery is a serverless, highly scalable, and cost-effective multi-cloud data warehouse designed for high-speed SQL analytics. It is fully managed, offering users the ability to run complex SQL queries against large datasets in a fast and reliable manner. BigQuery’s serverless nature means that users don’t have to worry about infrastructure management. BigQuery is also tightly integrated with Google Cloud’s ecosystem, offering smooth connections with services like Google Data Studio, Cloud ML Engine, and Google Sheets.

Architecture and Scalability

Azure Synapse Analytics

Azure Synapse supports both provisioned resources (dedicated SQL pools) and serverless query (on-demand querying). This hybrid model allows you to choose between provisioned and pay-as-you-go resource consumption. Synapse is known for its scalability; you can allocate SQL pools to specific workloads, scaling compute and storage resources independently.

Synapse also has an MPP (Massively Parallel Processing) architecture, which enables the processing of large datasets by distributing the workload across multiple compute nodes. Its integration with Azure Data Lake Storage allows for seamless data ingestion and management across multiple formats, such as CSV, Parquet, and ORC.

Google BigQuery

Google BigQuery is entirely serverless, meaning you don’t have to provision or manage any resources. BigQuery automatically scales compute and storage as needed, with pricing based on the amount of data queried and the duration of queries. BigQuery’s separation of storage and compute ensures that users only pay for what they use, optimizing cost-efficiency for varying workloads.

BigQuery is built on Google’s proprietary Dremel architecture, which allows for real-time analytics on petabyte-scale datasets by splitting queries across thousands of servers in parallel. BigQuery is ideal for organizations looking for near-instantaneous query performance across massive datasets, thanks to its fully managed environment.

Performance: Query Speed and Latency

Azure Synapse Analytics

Synapse provides strong performance, particularly for enterprises that need to blend big data analytics with traditional SQL-based querying. The dedicated SQL pools offer predictable performance for enterprise data warehousing, while the serverless SQL pools provide flexibility when querying data on demand without requiring pre-provisioned compute resources.

For interactive queries and exploratory analysis, Synapse’s on-demand query capability is competitive. However, compared to BigQuery’s real-time query optimization, Synapse’s performance may lag slightly when it comes to handling massive, ad-hoc query volumes at scale.

Google BigQuery

BigQuery’s strength lies in its fast, real-time analytics. Built on Dremel, BigQuery executes queries in parallel across distributed clusters, delivering sub-second query performance even on petabyte-scale datasets. This makes BigQuery particularly advantageous for real-time data analysis, marketing analytics, or IoT data streams, where speed is a critical factor.

In benchmarks conducted by GigaOM, BigQuery consistently performed faster than other data warehouses, including Synapse, especially for large-scale, complex queries involving billions of rows.

Integration and Ecosystem

Azure Synapse Analytics

Synapse’s biggest advantage is its seamless integration with the Microsoft ecosystem. It easily connects with Power BI, Azure Data Lake Storage, Azure Machine Learning, and Azure Data Factory, making it an excellent choice for enterprises that rely on Microsoft’s tools for their analytics workflows. Synapse Analytics also supports Spark-based data processing, enabling users to perform big data analytics on non-relational data.

Synapse also integrates well with Azure Active Directory (AAD) for managing permissions and security, offering deep integration for enterprises needing role-based access control and compliance.

Google BigQuery

BigQuery’s deep integration with Google Cloud makes it a powerful tool for organizations already using Google services. BigQuery integrates seamlessly with Google Cloud ML, Dataflow, Pub/Sub, and Google Sheets, allowing users to incorporate machine learning models and real-time streaming data into their queries. For data visualization, Google Data Studio provides a free and highly customizable tool to explore and present data directly from BigQuery.

One of BigQuery’s most attractive features is its multi-cloud functionality, allowing users to analyze data across Google Cloud, AWS, and Azure via BigQuery Omni, a service that extends BigQuery’s querying power to datasets residing in other clouds.

Security and Compliance

Azure Synapse Analytics

Azure Synapse provides comprehensive security features, including data encryption both at rest and in transit, Advanced Threat Protection, Dynamic Data Masking, and Always Encrypted for sensitive data. For enterprises with strict compliance needs, Azure Synapse supports a wide range of certifications, including HIPAA, SOC, ISO 27001, and GDPR.

Additionally, Synapse integrates tightly with Azure Active Directory for identity and access management, enabling precise control over user permissions and security policies across the Azure ecosystem.

Google BigQuery

Google BigQuery also offers strong security measures, including encryption at rest and in transit, customer-managed encryption keys, and integration with Google Cloud Identity and Access Management (IAM). BigQuery supports certifications like SOC 1/2/3, ISO 27001, HIPAA, and GDPR, making it a secure choice for enterprises handling sensitive data.

BigQuery stands out for its multi-cloud compliance capabilities through BigQuery Omni, ensuring that enterprises can maintain compliance even when querying data across different cloud providers.

Cost and Pricing Model

Azure Synapse Analytics

Azure Synapse offers flexible pricing, where you can choose between provisioned (dedicated) or serverless models.

• Provisioned SQL Pools: Pricing is based on the amount of compute resources allocated. For example, DWU (Data Warehouse Units) determine the compute power of the provisioned SQL pools, where you pay a fixed cost based on DWUs allocated.
• Serverless SQL Pools: This model charges based on the amount of data processed per query, making it a good option for ad-hoc querying without committing to dedicated resources.

The combination of pay-per-use and provisioned resources allows for cost optimization, but users need to be mindful of the resource management for provisioned SQL pools to avoid unnecessary costs.

For more detailed pricing, visit the Azure Synapse Pricing Guide.

Google BigQuery

BigQuery uses a fully pay-per-query pricing model, which can be highly cost-effective for businesses that need elasticity and don’t want to manage infrastructure. You pay based on the amount of data processed by your queries, making it highly predictable for low-to-medium query workloads.

BigQuery also offers a flat-rate pricing model for enterprises running a high volume of queries, providing more predictable costs by purchasing a block of query processing power measured in slots.
