Cloud Infrastructure as Code

Transcript

1. Cloud Infrastructure as Code 1
2. Infrastructure as code 2 The goal is fully automated cloud infrastructure. A technical domain revolving around building and managing infrastructure programmatically. We get there with Infrastructure as Code.
3. Re-Constructible Cloud Business 3 Enable the reconstruction of the business from nothing but a source code repository, an application data backup, and bare metal resources.
4. Configuration Management 4 Keep track of all the steps required to take bare metal systems to doing their job in the cloud. And this available as a service in your cloud infrastructure.
5. Systems Integration 5 Taking all the systems that have been configured to do their job, and make them work together to actually run the infrastructure.
6. Cloud Automation Framework 6 A framework for fully automating infrastructure
7. Cloud Integration Framework Helps manage cloud infrastructure 7 ¨  Puppet - open source ¤  https://github.com/puppetlabs/puppet ¤  www.puppetlabs.com ¨  Chef – open source ¤  https://github.com/opscode/chef ¤  www.opscode.com
8. Use API to provision resources 8 •  Compute resources such as •  Rackspace Cloud Servers or •  Amazon EC2 •  Storage resources such as •  Amazon S3 or •  Rackspace Cloud Files •  Networking resources to interconnect your cloud resources
9. You can do the same with GUI but… 9 ¨  APIs let you programmatically allocate/release resources ¨  Public / private / hybrid cloud
10. Write code to manage infrastructure 10 ¨  Maintain state of resources on the machines ¨  Generate configurations ¨  Reduce management complexity ¨  Version control your infrastructure code so you can roll back and correct mistakes if any
11. Declarative Interface to Resources 11 ¨  Define the outcome ¤  Tell what is needed (not how to do)
12. Pull based operations (not push) 12 ¨  Lets a node configure itself when it comes online
13. Program your cloud infrastructure 13 ¨  So your cloud infrastructure creates itself ¤  Programmatically provision and configure ¨  Treat your infrastructure code like any other code ¨  Reconstruct business from code repo, data backups and bare metal machines in the cloud ¨  Begin with a disaster plan – not after the fact.
14. Write code to build anything 14 ¨  Simple internal apps ¨  Complex internal apps ¨  Corporate workstations ¨  Hadoop clusters ¨  IAAS, PAAS, SAAS applications ¨  Storage systems ¨  Any apps that you want to deploy on the cloud
15. And manage it simply 15 ¨  Auto re-configure everything ¨  Balance the load ¨  Collect metrics ¨  Use monitoring systems ¨  Writing code to build cloud makes migrations trivial ¤  Because you can migrate clouds programmatically.
