Usecase: cloud hybridationleveraging on Docker 1.12
@adrienblind @lpiotPlease twit us on #experiences !
On-demand & pay-per-use
DevOps compliant : easy automation, Infra-as-code, versionnable, reproductible
Leads to new usecases: elastic applications, ephemeral environments…
The cloud is sexy
@adrienblind @lpiotPlease twit us on #experiences !
Versatile resources Fail-over through distributed architecture Rebuild vs. restore Frequency of reinstall
Pay per-use but… low perf/cost ratio load-balancing network-based architecture : asynchronous
architecture
A cloudy picture
@adrienblind @lpiotPlease twit us on #experiences !
Security No network peripheral security New organisation-based security model
Managed services very appealing but… vendor lock-in consequences on project/prod collaboration
Keep a decent ROI on recent on-premise assets
A cloudy picture

Docker benefits‘’A universal, self-sufficient and standard artifact embedding an app module,
and its subsequent infrastructure configuration’’
Docker provides both the artifact and the ecosystem to handle it!
Immutable
Portable Lightweight
Incremental
Versionned/taggedDisposable

Topology & orchestration
App 3
App 2
App 1
X64/WIN X64/LINUX ARM/LINUX
An app is made of several atomic containers
Compose, Bundle & Service enable to manage topologies of containers accross a single cluster of nodes
Docker should support ARM & Windows enabling to describe various types of assets in the topology
Third-part assets may be handled artificially through abassador containers

Extend your network up to cloud vendors platform (VPN, dedicated connections…)
Set up an hybrid docker swarm cluster on top of this various commodites

Conclusion
@adrienblind @lpiotPlease twit us on #experiences !
Docker offers a nice opportunity to create an abstraction layer to facilitate transition to the cloud
Hybridation facilitates composite orchestration… when it’ll be fully operational

Step 1 Shift to docker packaging pardigmes Start deploying your apps through docker (trough CD pipelines
for instance) Step 2
Shift to dynamic orchestration: swarm cluster handles container deployments over the cluster, ensures desired instances are up, etc.
Step 3 Extend your local own cluster to third-part vendors
Step 4 Shift to self-healing clusters (autoscaling nodes for instance)
Plan your migration
