The Twelve-Factor App: Backing Services, Building and Releasing, Stateless Processes

 

Surveys – Wow we forget about them and ramble...sorry guys!

 

Mark Tinsley – PHP Composer – thanks for the tip!

Joe made a game in Javascript (using dozens of libraries):

Box Pusher! (game name of the year)

Probably want to listen to the first three parts of the 12 Factor App if you missed it:

IV. Backing Services

  • Any resource consumed over the network: databases, mail servers, cloud services, etc.

  • Anything external to your app (but could be local to your environment)

  • Should not have to change any code to redeploy – should be config changes if anything

  • Clearly Tech – Importance Rating: High

 

We've mentioned Splunk, and if you're not familiar, it's an enterprise piece of software that will aggregate logs from multiple sources (servers, computers, etc):

V. Build, Release, Run

  • Build stage – transform which converts the code repo into an executable bundle

  • Release stage – combines the build with the required config and deposits it somewhere

  • Run – runs the app in the execution environment (development, staging, production, other)

  • Rolling back may be more complicated when you start talking about database schemas / data changes

  • Clearly Tech – Importance Rating: Conceptual???

 

Version numbers? What do you prefer? Version numbers with major and minor revisions? Or do you prefer timestamps?

 

 

VI. Processes

  • Stateless and Share Nothing

    • No local session

    • Make sure saving files go to an available repository

  • Clearly Tech – Importance Rating: High (Joe wants higher than high)

Tips

 

Allen: Find problematic queries that are killing your SQL Server...replace 123 with the spid from sp_who2.

 

sp_who2 'active'

DBCC INPUTBUFFER(123)

 

If you want to be mean....replace 123 with the spid from sp_who2

KILL 123

 

Additionally, if there's high CPU and low I/O, it's likely either a missing or a fragmented index.
