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

Please provide Jenkins job for that. Our database is located on

AWS (MySQL).

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
