Why migrate/replicate workloads ? Manage Capacity utilization => Cloud bursting Disaster recovery on to a secondary site (Cloud) Move across vendors due to other SLA requirements, cost etc
Types of workload migrations Individual Application level Manual App configuration + data has to be migrated Image level Different image formats, sometimes not easy to convert in to OVF, RAW formats Customization on firewall/network/storage
How ? Create & register base images Network configuration Maintain network configs from source to destination Private IP can be maintained with the help of “bridge”s Static IP assign is still an open issue in Docker Port re-direction binds host port to container port Migrate Data/volumes Migrate data using rsyn, dd etc from one environment to another if the data cannot be made accessible to the destination host OS Additional volumes associated with the containers can be shared as volumes from the host OS or from another container
Benefits Continue to use the benefits of Cloud Instant resource provisioning in cloud Scale for High Availability Automate Docker configuration through puppet/chef
