ClustrixDB vs Microsoft SQL Server: What are the differences?
# Introduction
In this comparison, we will analyze the key differences between ClustrixDB and Microsoft SQL Server.
1. **Scalability**: ClustrixDB is specifically designed to scale out horizontally by adding nodes to increase performance and capacity. In contrast, Microsoft SQL Server relies on vertical scaling by upgrading hardware resources on a single server.
2. **Architecture**: ClustrixDB uses a distributed shared-nothing architecture where data is distributed across all nodes, allowing for high availability and fault tolerance. On the other hand, Microsoft SQL Server utilizes a centralized architecture with a single point of failure.
3. **Data Distribution**: ClustrixDB automatically distributes data evenly across nodes for balanced workload distribution, leading to improved performance. In contrast, Microsoft SQL Server requires manual partitioning and sharding to distribute data effectively.
4. **ACID Compliance**: Both ClustrixDB and Microsoft SQL Server are ACID compliant, ensuring data consistency and reliability. However, ClustrixDB achieves this on a distributed scale while Microsoft SQL Server does it on a single-node level.
5. **High Availability**: ClustrixDB offers built-in high availability features such as automatic failover and self-healing capabilities to ensure continuous uptime. Microsoft SQL Server requires additional configuration and external tools to achieve similar high availability.
6. **Cost and Licensing**: ClustrixDB is a subscription-based service with pricing dependent on the number of nodes, while Microsoft SQL Server follows a traditional licensing model with upfront costs and additional fees for features like high availability.
In Summary, ClustrixDB and Microsoft SQL Server differ in scalability, architecture, data distribution, ACID compliance, high availability, and cost/licensing models.
