Unofficial Laws of JEE Systems Administration
For any budding web applications systems administrator, here is my tongue-and-cheek list of laws and axioms you will discover over the course of your careers to be self-evident.
- The JVM never crashes unless you have dinner plans.
- It's always the database.
- Except when it's the network.
- Logging in XML means your developers hate you.
- Base HREFs in a web page are the entry to a support abyss.
- You will be befriended by a web developer who doesn't know how DNS, SSL, or HTTP works.
And here are some relevant to systems administration in general:
- State of the Art is a euphemism for 'Difficult to Support'.
- A Data Center Migration is a form of Abstinence.
- The load-balancer gets 100% of the blame while only being responsible for 2% of issues.
- If you have specialists on a team of systems engineers, their specialty always fails when they are on vacation. Always.
- PCI Compliance is a Paradox
- Next quarter, you will not be PCI Compliant
