Suggestion and guidance on deployment architecture of enterprise production environment
Partial adjustment: such as changing operating systems and database system versions; some configuration change requiring assessment by Application Team. Workload of assessment is not much after migration.
Straight Migration: use the certain migration tool instead of rewriting or patching any codes. Move from the original platform (e.g. VMWare) to the new one (e.g. AWS). Less influence on business. Only about access methods (e.g. change of IP address) etc. require Application Team’s cooperation.
Provide consulting and advising services on intensive reformation, including: use intensive reformation for migration, e.g. replace EJB with Tomcat; Require thorough assessment by Application Team and intensive test after migration; Combined manual and automatic methods when transforming and deploying.
