In the battle over cloud providers, the bid for the United States Department of Defense (DoD) Joint Enterprise Defense Infrastructure (JEDI) contract is a big deal. The DoD released on October 25, 2019 that they are awarding the JEDI contract worth up-to $10 Billion ($10,000,000,000) over the next 10 years to Microsoft. They have ultimately chosen Microsoft, and Microsoft Azure, as the cloud of choice to standardize on a single cloud vendor to build out their enterprise cloud.

Domain Command Patterns - Validation 

A next-level validation is domain validation, or as I've often seen referred, "business rule validation". This is more of a system state validation, "can I affect the change to my system based on the current state of my system". I might be checking the state of a single entity, a group of entities, an entire collection of entities, or the entire system. The key here is I'm not checking the request against itself, but against the system state.  

• VS is more responsive when running Git operations.
• Debugging large solutions with /debug:fastlink PDBs is more robust. Changes in the PDB/DIA lead to reduced latency and a 30% reduction in heap memory consumption in the VS debugger that used to cause crashes.
• C++ compiler bugfixes:
  • Fix for the SSA optimizer incorrectly sinking a function call past a store to a variable used in a __finally handler.
  • Fix for the SSA optimizer sometimes incorrectly analyzing memory loads from locations with negative offsets.
  • Fix for the optimizer incorrectly transforming a pre-incremented loop into a post-incremented loop. This was found compiling the ICU project.
• Microsoft bumped up the Java™ Development Kit 8 to Update 172 (JDK version 8u172).
