Infrastructure In The Cloud Era


Published on

From the Web 2.0 Expo!

Web Operations is always moving forward, at the cutting edge of every major trend. The latest leap is having a fully automated infrastructure – lightning fast provisioning, integrated monitoring & trending, and trivial application deployment.

Utilizing a mixture of open source tools (such as Chef, Nanite, CouchDB, and RabbitMQ) and battle-tested techniques, Adam and Ezra will show you how to build an infrastructure that’s easy to manage, integrates with your application, and is self-documenting. Along the way, they’ll give you the key insights you need to get maximum benefit from these technologies for your business.

The speakers come from two companies well-known in this space. Engine Yard is moving to the cloud – in addition to their own internal hosting offering they built their stellar reputation on. Opscode brings “infrastructure automation to the masses”. Born from years of experience building fully automated infrastructure for dozens of startups, they are the creators of Chef.

Rarely idempotent. More repeatable. Hard to collaborate. Ad-Hoc Knowledge is dispersed. Brittle. Built your way, with your model. No API. Repeatable. Infrastructure as Idempotent.

  25. In Practice
  26. Typical Peak Load 1. Bring on capacity as traffic ramps up 2. Take down capacity as it ramps down 3. 10-15 Minutes on either side, fully unattended Graphs in this portion of the presentation taken from Theo Schlossnagle
  27. Atypical Load No way However, around you are Capacity still better Planning off! 1. Hope you know it is coming. 2. Increase capacity in advance. 3. Take down capacity as it ramps down. Graphs in this portion of the presentation taken from Theo Schlossnagle
  28. 1. Signal Command and Control 2. Analyze Responses 3. Rinse and Repeat 4. Profit
  29. 1. Your infrastructure is disposable. 2. Make sure you can turn each layer off. 3. New efficiencies often lead to new hard problems.
