4. Process Automation
• End-to-end automation
• Supports business goals
• Optimize the system, not the parts
5. Introduction
Take a toolchain approach
E-commerce and software-as-a-service business models have matured quickly, but the
quality of the web operations that support these businesses has lagged behind.
Outages are all too common. High variability and defect rates are bemoaned but have
become an accepted reality. Key engineers spend all day (and sometimes all night)
mired in deployment issues and bottlenecks. And topping it all off, what tooling that
does exist are usually a custom one-offs that are brittle and expensive to maintain.
Today’s business of operating software over the Web as a revenue producing service is a
” Today’s business of dramatic departure from the days when software was primarily produced for delivery on
operating software over the physical mediums and IT Operations was considered a back-of-the-house support
Web as a revenue producing function. Shouldn't we be completely rethinking our tooling and operational capabilities
service is a dramatic to match these new innovations?

There are multiple factors that go into achieving excellence in Web Operations, but the
linchpin that holds it all together is a fully automated provisioning system.
In this paper we will be:
1. Defining what we mean by "fully automated provisioning"
2. Explaining why virtualization and cloud computing efforts fail without fully
automated provisioning capabilities
3. Proposing a reference open source tool chain for fully automated provisioning
4. Describing a live implementation where a leading online retailer is actively rolling
out a fully automated provisioning system using all open source tools
Unix Tool Chain 2 Web Ops 2.0: Achieving Fully Automated Provisioning
7. Design points
1. Everything is code
2. Everything is packaged
3. Separate code and configuration
4. Separate environment-dependent attributes
5. Balance distributed vs local orchestration
6. Resolve directed vs convergent orchestration
7. Integrate application and infrastructure provisioning
8. Design for flow not the organization
