 Overall, the extensibility framework is almost identical for R and Python, with some minor differences in the details of the launchers that are called, configuration options, and so forth. For further information about the implementation for a specific language, see these topics:

-In SQL Server 2016, numerous changes were introduced to the database engine to support execution of R scripts using SQL Server. In SQL Server 2017, this underlying infrastructure was improved to add support for the Python language.

 The goal of the extensibility framework was to create a better interface between SQL Server and data science languages such as R and Python, both to reduce the friction that occurs when data science solutions are moved into production, and to protect data that might be exposed during the data science development process.

+To meet these goals, the architecture of SQL Server 2016 R Services and SQL Server 2017 Machine Learning Services for R and Python is based on these core concepts:
 
 + **Multi-process architecture**
- Both R and Python are open-source languages with rich and enthusiastic community support. Therefore, it is important to maintain full interoperability with open source R and Python.
 
-  Open source distributions of R and Python are installed with SQL Server under license, and can function independently from SQL Server if needed.

 + **Scalability and performance**
+
   Integration with SQL Server is key to improving the usefulness of R and Python in the enterprise. Any R or Python script can be run by calling a stored procedure, and the results are returned as tabular results directly to SQL Server, making it easy to generate or consume machine learning from any application that can send a SQL query and handle the results.
 
   Performance optimization relies on two equally powerful aspects of the platform: resource governance and parallel processing using SQL Server, and distributed computing provided by the algorithms in **RevoScaleR** and **revoscalepy**.
 
 
-## Solution Development and Deployment Workflow
+## Solution development and deployment
 
 In addition to these core goals for the extensibility platform, the machine learning services in SQL Server are designed to provide strong integration with the database engine and the BI stack, with these benefits:
 
 + Performance and resource management through traditional monitoring tools
 + Easy use of Python and R data by BI suites or any application that can consume SQL query results
 + Much lower barrier for enterprise development of machine learning solutions

 Let's see how it works in practice.

-1. Data is kept within the compliance boundary and use of data can be managed and monitored by SQL Server. Meanwhile, the DBA has full control over who can install packages or run scripts on the server. If so desired, the DBA can also delegate permissions on a database level to data scientists or managers. 
-2. Data scientists can build and test solutions in their preferred R or Python environments, disconnected from the server. 
-3. The SQL developer can use familiar tools such as Management Studio or Visual Studio to integrate the R or Python code with SQL Server. The tight integration means that the savvy developer can choose the best tool to optimize each task. For example, you might use SQL for some feature engineering tasks and R for others. You might embed Python script in an Integration Services task to perform sophisticated text analytics.

 4. Tested and ready-to-deploy solutions can be optimized using SQL Server technologies, such as columnstore indexes, for better performance. Newer features let you batch-train many small models in parallel on partitioned data set, or score millions of rows in using native SQL code optimized for machine learning tasks.
 5. Ready to lift off? You can easily expose your predictive solutions to the BI stack or external applications by using stored procedures.
