Comparison Factors – Azure Synapse Analytics vs Azure SQL Database
While selecting a cloud-based data warehouse solution for your business, it’s important to evaluate different options. Comparing key differentiating factors can help you make an informed decision.
Let’s delve into a comparison of Azure Synapse vs Azure SQL Database.
Azure Synapse vs Azure SQL DB: Workload
Azure Synapse Analytics and Azure SQL Database are powerful cloud-based database solutions optimized for different types of workloads.
Azure Synapse Analytics can handle complex analytical workloads like OLAP (Online Analytical Processing). In other words, it’s great for handling complex and ad-hoc analysis of data in real time.
Synapse breaks down complex tasks into smaller, more manageable tasks using a decoupling and parallelizing approach. By processing these tasks simultaneously, it becomes easier to analyze large datasets.
OLAP workloads often store data in a denormalized form using a schema, and Azure Synapse Analytics is designed to handle these types of datasets. Synapse provides a highly scalable and flexible platform for storing and processing large volumes of data.
On the other hand, Azure SQL Database is a fully managed relational database service that is designed to handle transactional workloads. Which typically involves smaller data sets with a higher frequency of short and simple read/write operations.
In these scenarios, data is usually stored in a normalized form, meaning it is structured into multiple tables with relationships between them. It is an ideal solution for transactional workloads such as online transaction processing (OLTP) and line-of-business (LOB) applications.
SQL Database is a good fit for organizations that require high transactional throughput, low latency, and high availability.
And Azure Synapse Analytics is optimized for complex querying and analysis.
Azure Synapse vs Azure SQL DB: Polybase
Azure Synapse Analytics offers a powerful feature called PolyBase. It allows users to query and access data from external sources like Azure Blob Storage, Hadoop, or other data sources using T-SQL.
As a result, PolyBase makes it easy to connect to different data sources without moving or copying the data. This enables users to integrate and analyze diverse datasets efficiently.
Azure SQL database doesn’t support PolyBase. However, it does provide similar functionality through its External Tables feature, which allows users to query data stored in external data sources using T-SQL statements.
But, the External Tables feature does not offer the same level of integration and functionality as PolyBase in Azure Synapse Analytics.
Azure Synapse vs Azure SQL DB: Data Security
Azure Synapse Analytics provides more extensive security features than Azure SQL DB.
Firstly, Azure Synapse Analytics includes a dedicated Security Center that offers a centralized view of security policies, recommendations, and alerts for Synapse workspaces. This enables you to easily identify potential security threats and take action to mitigate them.
Azure SQL Database, on the other hand, does not have a dedicated Security Center.
Secondly, Azure Synapse Analytics includes advanced threat detection capabilities, which can automatically detect and respond to potential security threats.
Again, this is not available in Azure SQL Database, where users would need to manually monitor their databases for potential security threats.
Azure Synapse vs Azure SQL DB: Scalability
Azure Synapse Analytics is a cloud-based analytics service specifically designed to process large amounts of data. It’s specifically optimized for data workloads of 1+ TB. You can also store up to 240 TB for rows and unlimited storage for column store tables.
Azure Synapse Analytics is a better choice for managing and analyzing large-scale data workloads. Additionally, it provides an all-in-one solution for storing, integrating, and analyzing massive data sets.
On the other hand, Azure SQL Database is a better choice for smaller database sizes, as it can efficiently scale up or down based on workload demands. It offers different pricing tiers to cater to different workloads and can quickly adapt to handle varying workloads.
Therefore, choosing the appropriate service depends on the size and complexity of the data workload. Users should choose the most suitable option based on their specific needs.
Azure Synapse vs Azure SQL DB: Data Backup and Replication
Both Azure Synapse Analytics and Azure SQL Database offer automatic backups, but there is a difference in the backup retention periods they provide. Azure SQL Database provides automatic backups that are stored for up to 35 days. This means users don’t need to manage backups manually and can restore data from any point in the past 35 days.
On the other hand, Azure Synapse Analytics provides backup retention periods ranging from 7 to 35 days.
This gives users the flexibility to choose the retention period that best fits their needs. However, this also means that users need to manage their backups proactively and may have a more limited range of restore points to choose from.
Azure Synapse Analytics offers a broader range of replication options than Azure SQL Database. Synapse includes both asynchronous and synchronous replication. It provides advanced tools for monitoring and managing replication status, such as the ability to monitor replication health and set up alerts.
Whereas Azure SQL Database offers basic data replication options such as read replicas, automatic failover, and point-in-time restore to help ensure data availability and recovery.
While both services provide data replication features, Azure Synapse Analytics provides more extensive options for data replication. Therefore Synapse is a better choice for organizations that require more complex replication scenarios.
Azure Synapse vs Azure SQL DB: Data Analytical Capabilities
Azure Synapse Analytics is specifically designed to handle large-scale analytical workloads, while Azure SQL Database is better suited for smaller analytical workloads.
Azure Synapse Analytics provides built-in support for advanced analytics tools like Apache Spark and machine learning services. This makes it easier for users to perform complex analytical tasks like predictive modeling and data mining. In contrast, Azure SQL Database has limited support for advanced analytics tools.
Azure Synapse Analytics also offers real-time analytics capabilities through its integration with Azure Stream Analytics, allowing users to analyze streaming data in real time.
Although Azure SQL Database can handle real-time analytics, it isn’t an ideal choice because it primarily focuses on transaction processing rather than analytical workloads.
Therefore, Azure Synapse Analytics is a better fit for large-scale and complex analytical workloads. And Azure SQL Database is better suited for simpler analytical tasks and transaction processing.
