1. Migrating to the Cloud in 20 minutes
   Jon Topper The Scale Factory
   
2. In 20 Minutes What to consider Characteristics of cloud computing Approaches to avoid What to do instead
3. What do you care about? Cost (CapEx / OpEx) Capacity Elasticity Security Availability Geography Agility Cool factor?
4. Cloud Characteristics “There is no cloud, just other people’s computers” “Everything fails, all the time” - uptime ownership Multi-tenant Less control over naming, addressing More rapid provisioning of resources
5. Don’t do this Forklift migrate Cloud as DR Manual provisioning/configuration/deployment Mistake scalability for performance Assume reliability
6. Do This Instead! Design Build Operate
7. Lifecycle Operate 95% Design / Build 5%
8. Design Design to operate KISS Security design from day one Use the strengths of the cloud platform Segregate state Treat instances as disposable Use LB/failover for HA (across AZ) Remain portable
9. Build Build machine templates (Packer) Provision infrastructure (Terraform, CloudFormation) Configure infrastructure (Puppet, Chef, Ansible, Salt) Deploy software
10. Operate Orchestrate patching / incremental change Monitor service availability Monitor resource usage Monitor performance metrics Monitor business metrics Aggregate logs Continuous Improvement
