Introduction • Patrick.Debois@jedi.be • Independent Consultant • Projects & Operations • Technical & Human Factor • Try to get the FUN back in working

The Audience is listening...

Fighting your way past operations...

You might get ‘Luke’y as they screw up.

They WILL try to freeze your project

But you now dance to a new tune...

Will the battle ever end?

No thanks, they only stay here for the project and I Our project team is building You’ll run have to clean it up! a new application it for next 5 years Commited / Involved

Now on Itunes The Lost Use Cases of Operations Order it now!

Example 1: Monitoring • 1 functionality = 3 implementations • Unit Tests • System Tests • End-To End Monitoring • Component Monitoring is not enough • Reports on usage, trends • One failure should not make OPS blind

Example 2: Disaster • Start/Stop Sequence • Database, Directory Server, Application Server, FileServer ... • Database down, what with connection pooling? Frameworks hide things. • Active/Active vs. Active/Passive • It will fail, how bad will it be? Risk vs. Budget

Example 3: Passwords

Example 3: Passwords • Application Server

Example 3: Passwords • Application Server • Monitoring Users

Example 3: Passwords • Application Server • Monitoring Users • Backup User

Example 3: Passwords • Application Server • Monitoring Users • Backup User • Database Users

Example 3: Passwords • Application Server • Monitoring Users • Backup User • Database Users • Endusers

Example 3: Passwords • Application Server • Monitoring Users • Backup User • Database Users • Endusers • Certiﬁcates

Example 3: Passwords • Application Server • Monitoring Users • Backup User • Database Users • Endusers • Certiﬁcates • Power Users

Example 3: Passwords • Application Server • Scripts • Monitoring Users • Backup User • Database Users • Endusers • Certiﬁcates • Power Users

Example 3: Passwords • Application Server • Scripts • Monitoring Users • Mail User • Backup User • Database Users • Endusers • Certiﬁcates • Power Users

Example 3: Passwords • Application Server • Scripts • Monitoring Users • Mail User • Backup User • .... • Database Users • Endusers • Certiﬁcates • Power Users

Example 4: Conﬁg Files • Right amount of conﬁguration • Operation does not care about threads, class loaders , Connection Pools • They care about FilePath changes, IP Changes, Name changes ... • Do you require downtime?

Example 4: LogFiles • Java Exceptions are usefull for developers • LogFiles (more then debug, warn, ﬁnest) • Dynamically enable logging

But off course it’s all a software design problem!

What will it cost you? • 1 day late project vs. 1 day downtime • Week work versus Weekend work • Test Environment vs. Risk of Patches • 10 users in Pilot vs. 10.000 user in Live • Your product owner might rethink priorities

“Enterprise” Triangle

Project “Enterprise” Triangle

Project Operations “Enterprise” Triangle

Joined Effort • Backup, Monitoring of your project environment • One less worry on the infrastructure • Test environments can be fully sized, representative environment

Operations needs help • Project creates tools • They use tools • Operations misses f.i. • Refactoring a Server • Unit tests for OS

Aford a test Deadthstar? • A good test environment will serve for the project • But also in operations • for patches • testing incidents • upgrades • reuse of unit testing

What can YOU do?

You care about software

One Partner is Safer

Practice Early

Invest money for the future

Real Life begins at 40.

Real Life begins at 40. Software begins at Operations

Non functional can be important

Let go, but not without support

Provide the necessary tools

In good and bad times In Project and Operations

Grow old together
