SSIS Architecture

Referred from MSDN

SSIS Designer 

SSIS Designer is a graphical tool that you can use to create and maintain Integration Services packages. SSIS Designer is available in Business Intelligence Development Studio as part of an Integration Services project 

 

Runtime engine 

The Integration Services runtime saves the layout of packages, runs packages, and provides support for logging, breakpoints, configuration, connections, and transactions.

 

Tasks and other executables 

The Integration Services run-time executables are the package, containers, tasks, and event handlers that Integration Services includes. Run-time executables also include custom tasks that you develop.

Data Flow engine (also known as the pipeline) and Data Flow components 

The Data Flow task encapsulates the data flow engine. The data flow engine provides the in-memory buffers that move data from source to destination, and calls the sources that extract data from files and relational databases. The data flow engine also manages the transformations that modify data, and the destinations that load data or make data available to other processes. Integration Services data flow components are the sources, transformations, and destinations that Integration Services includes. You can also include custom components in a data flow.

API or object model 

The Integration Services object model includes managed application programming interfaces (API) for creating custom components for use in packages, or custom applications that create, load, run, and manage packages. Developer can write custom applications or custom tasks or transformations by using any common language runtime (CLR) compliant language.

Integration Services Service 

The Integration Services service lets you use SQL Server Management Studio to monitor running Integration Services packages and to manage the storage of packages.

 

SQL Server Import and Export Wizard 

The SQL Server Import and Export Wizard can copy data to and from any data source for which a managed .NET Framework data provider or a native OLE DB provider is available. This wizard also offers the simplest method to create an Integration Services package that copies data from a source to a destination.

 

Other tools, wizards, and command prompt utilities 

Integration Services includes additional tools, wizards, and command prompt utilities for running and managing Integration Services packages.
