The new AWS Asia Pacific (Hong Kong) Region will have three Availability Zones and be ready for customers for use in 2018. As a result, we have opened 43 Availability Zones across 16 AWS Regions worldwide. Since then, AWS has added two more PoPs in Hong Kong, the latest in 2016. In 2013, AWS opened an office in Hong Kong.

There is no way to model how much more traffic you can send to that system before it exceeds it’s SLA. This is unfortunate, because we’d really like to be able to build systems that have an SLA that we can share with the consumers of our interfaces, and be able to measure how well we are doing.

The system table sys.sysprocesses was replaced way back in SQL Server 2005 by a set of dynamic management views (DMVs), most notably sys.dm_exec_requests , sys.dm_exec_sessions , and sys.dm_exec_connections. We recommend that you use the current SQL Server system views instead. Why this is a problem.
