Schoolnet Technical Improvements for December and January

• Up to 90 “minor” optimizations and enhancements have been applied to version 16.0

• There are three “major” improvements which will distribute and balance the load on Schoolnet:

– Assessments - Created a dedicated database instance to serve the assessment administration activities

– Assessment Reporting – Created a read-only database instance to serve selected reporting activities

– Static Content - Added a Content Delivery Network (CDN), which will place static content closer to the requester without placing additional burden on the application servers

Long Term Schoolnet Solution

• Migrate to Schoolnet Version 16.2 in spring 2015. – Migrates Assessment Administration functions from SQL

Server to “Cassandra” database, which is a much more scalable database platform.

– Includes additional optimizations and functionality

• Monitor the deployment and performance of Schoolnet Version 16.2 with Cassandra in other state instances

• Conduct extensive functional and load tests of version 16.2 in an upgraded NC test environment that mimics production
