What is scale out in SQL Server?
SQL Server Integration Services (SSIS) Scale Out provides high-performance execution of SSIS packages by distributing package executions across multiple computers.

How do NoSQL databases scale horizontally?
Scalability. In contrast, NoSQL databases are horizontally scalable, which means that they can handle increased traffic simply by adding more servers to the database. NoSQL databases have the ability to become larger and much more powerful, making them the preferred choice for large or constantly evolving data sets.
Is SQL Server horizontal scaling?
Horizontal and vertical scaling Horizontal scaling refers to adding or removing databases in order to adjust capacity or overall performance, also called “scaling out”. Sharding, in which data is partitioned across a collection of identically structured databases, is a common way to implement horizontal scaling.
How can you tell SQL Server is highly scalable?
Horizontal Database Scalability
- Data is fully replicated across all nodes. One primary copy accepts changes, and multiple active replicas are typically read-only, as in the SQL Server AlwaysOn Readable Secondaries or Replication features.
- Read and write operations are distributed across a number of nodes.
