2. 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

3. 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

4. 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

5. Benefits

Continue to use the benefits of Cloud



Instant resource provisioning in cloud
Scale for High Availability
Automate Docker configuration through puppet/chef
