Abstract

If you are using an infrastructure configuration management solution, and wondering how it fits with your Release Automation strategy, this session is for you.

Join us while we discuss how to get the most out of solutions like Chef and Puppet as part of your overall Continuous Delivery tool chain. Configuration Management solutions provide distinct capabilities to manage your infrastructure and can provide tremendous value alongside a release orchestration and automation solution like CA Release Automation.

In this session, we will demonstrate and discuss the unique strengths and overlapping capabilities of each solution and layout guidelines to help you determine the proper tool for each stage.

Configuration Management withRelease Automation

Configuration Management

Dzone, “2014 Guide to Continuous Delivery Survey”

49% Use configuration management tools like Puppet, Chef and CFEngine

73% Still use manual scripts for at least half of their infrastructure changes.

Challenges of Building a Continuous Delivery Tool Chain

100s, 1000s, 10,000s machines

Provision and Configure

Middleware, databases, load balancers

Applications with 100s of artifacts in multiple repositories

Short release cycles

Multiple releases per day/week/month

Balancing speed with quality

Application Delivery is Complex

Which Tool is the Right Tool?

Infrastructure provisioning and configuration management tools can perform some continuous integration tasks

Application release automation tools can provision environments

Continuous integration can deploy and test applications

The Ecosystem Is Complex

Build/CI Configure Test PromoteProvisionStore

Infrastructure as Code/Configuration Management

Automate IT infrastructure tasks

Build, deploy and manage

Reduce risk of failure due to configuration issues

Ensures a known state before deploying applications into environment

Configuration Management & Release Automation Core Use Cases

An Example – What are Chef and Puppet?

Automation platforms providing configuration

management across your environments

Build ManageDeploy In the data center+ in the cloud

Infrastructure + applications

Source: Chef and Puppet

Who Uses These Tools?

USER PERSONAE

TYPICAL CHEF/PUPPET USERS

Operations Teams

Dev/Ops Engineers

Platform Teams

RELEASE AUTOMATION USERS

Release Administrators/ Managers

Dev/Ops Engineers

Application Development Team members

Why Release Automation & Configuration Management?

Use configuration management solutions and release automation to make infrastructure configuration management an easy and seamless exercise for DevOps and Application Release teams within Continuous Delivery

Continuous Delivery teams need validation that systems are in a known state aligned to their application deployment baselines Configuration management solutions define

and maintain the state of servers

CA Release Automation

– Crosschecks configurations against the application and deployment baselines

– Determines drift across middleware, applications, and environments

COMBINED VALUE

A Coordinated Approach

RELEASE AUTOMATION

Deployment of complex multi-tier applications across heterogeneous environments

Reusable deployment processes

Deploy an application to any number of disparate environments BARE METAL

Install OS, patches, configurations (e.g. Win 2008 SP1, Security settings)

Install middleware (e.g. WebSphere, Tomcat, SAP, Oracle, etc. etc. etc.)

Middleware configuration (JDBC drivers, web server settings, DB logging, etc.)

APPLICATION TIER 1

APPLICATION TIER 2

APPLICATION TIER 3

CONFIGURATION MANAGEMENT

Prepares the server to host an application

Knows of only individual servers, not of tiered apps running ACROSS servers


…or this QA environment

…or any environment (dev, test, etc.) with some tier or tiers virtualized or in the cloud

Configuration Management & Release Automation

Configuration Management solutions could also be used to: Deploy applications Deploy application configurations

Release Automation solutions could also be used to: Deploy middleware Deploy middleware configurations Install OS, patches etc.

However, it is easier to use the solutions together and leverage their strengths as opposed to forcing edge cases

OVERLAPPING CAPABILITIES

Configuration Management & Release Automation

Release management analysis

Artifact management tracking

Configuration drift reporting across environments, applications and deployments over time

Pre-deployment verification of environments

Ensure known state

Identify points of failure

CORE COMBINED USE CASES

Out-of-Box Configuration Management Capabilities with Chef/Puppet

Out-of-Box CA Release Automation

Chef/Puppet Integration and Capabilities

Use Chef/Puppet and CA Release Automation to make infrastructure configuration management an easy and seamless exercise for DevOps and Application Release teams in a Continuous Delivery environment

Targeted at allowing Release Admins/ Managers from the release and application teams to work with Chef Recipes and Cookbooks, and Puppet Modules put in place by experienced Chef/Puppet Admins

Supports an Author and User approach for large scale adoption

No Need to be a MASTER with all



Setup and Connectivity

Includes OOB integration to Chef and Puppet Enterprise Servers and

Organizations from within CA Release AutomationDefine, login and use multiple Chef and Puppet Instances within the UI of RA



Setup and Connectivity

Provide Release Automation server type and environment mapping to Chef/Puppet role and environment mapping

Chef Recipes and Cookbooks, and Puppet Modules selection by environment for deployments as part of the SDLC



Application /Deployment Baselines

Association of Chef Cookbooks and Recipes, and Puppet Modules by environment to an application/deployment baseline

Understands changes that might break the expected version due to lack of communication between Chef/Puppet Admins and App teams

Baseline establishes the set point for configuration drift reporting across environments and deployments
