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
