4. IT Architecture vs. Design
 Both talk about specification, but to different degrees:
Architecture specification is more abstract and can be
implemented in more than one way
 Design is more concrete and requires to proceed to
implementation
 Architecture addresses alignment, construction, deployment,
operational and retirement aspects of solution; Design often is
just about construction

o Intrinsic inter-operability is given more importance than
custom integration
o Shared services is given more importance than specific-purpose
implementations
o Flexibility is given more importance than optimization
o Evolutionary refinement is given more importance than pursuit
of initial perfection

22. Homework for weekend
As a Couch I want to import any database dump on-demand, so
that it can be performed automatically, or in manual mode.
Please provide Jenkins job for that. Our database is located on
AWS (MySQL).

23. Homework for weekend
Register at Amazon AWS and get Free Tier
Create a new IAM user and attach the policy ”PowerUserAccess” on it
Create MySQL instance on RDS based on db.t2.micro
Create EC2 instance based on t2.micro
Install Jenkins on it, enable desired plug-ins if so
Create a Jenkins job that imports MySQL dump to the database
