Serverless computing is gaining popularity at an astounding speed. It is changing the way we approach development and operations. However, like any other technology, in order to reach maturity in the business world, it needs to be wrapped with best practices. Join Rackspace as we discuss serverless computing in general and we walk through live demos of continuous integration and continuous delivery pipelines using AWS tooling and best practices. In this session, we will touch on technologies like Lambda, CodePipeline, CodeBuild, and CluoudFormation.

Rackspace Best Practices

29. DEVOPS OVERVIEW

30. 30
DevOps Defined
Refer to a set of practices that
emphasize the collaboration and
communication of both software
developers and information
technology (IT) professionals while
automating the process of software
delivery and infrastructure changes. It
aims at establishing a culture and
environment where building, testing,
and releasing software can happen
rapidly, frequently, and more reliably.

Automating the Package Process
• Build
• Test
• Package
version: 0.1
phases:
install:
commands:
- echo "Installing dependencies”
pre_build:
commands:
- echo "Tests Running”
build:
commands:
- echo ”Compiling”
post_build:
commands:
- echo "Packaging & uploading to S3”
- aws cloudformation package …
artifacts:
files:
- .sam/pack.yml

63. Code Pipeline Cft (Partial…)
63
Automating the Deploy
• Why not deploy from the CodeBuild?
• Deploy from CodePipeline with
CloudFormation
