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

SOAo Business value is given more importance than technical strategyo Strategic goals is given more importance than project-specific
benefitso Intrinsic inter-operability is given more importance than custom
integrationo Shared services is given more importance than specific-purpose
implementationso Flexibility is given more importance than optimizationo Evolutionary refinement is given more importance than pursuit
of initial perfection

Infrastructure as Code
Scripts (Bash/sh, Ansible, PowerShell, PHP, etc.)
Frameworks (Python or Java based)
CI jobs, pipelines and scripts
Database dumps from frameworks
Configuration files, properties
All this stuff should be placed on a Git repository for further testing, delivery, applying, etc., i.e. usage on remote systems.

Questions?

Homework for weekendAs 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).
22 www.itea.ua
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
23 www.itea.ua
Check if dump applies correctly, and send an email when job is failed
