Companies turn to PaaS and Cloud Native Applications to gain agility and speed. To provide customer value, a fault tolerant infrastructure is essential. But what happens if an entire data centre, region, or even country should go offline? Cassandra holds the key to keeping application state in sync through replication, whilst Pivotal Cloud Foundry provides easy deployment to multiple IaaS providers. It also comes complete with a managed service offering for DataStax Enterprise. This talk will discuss how this setup can be deployed in one day, including demonstrations and a walk-through of the key concepts, approaches, and considerations.

“Cloud is about how
computing is done, not
where”

4. Cloud Native
• Changing the way enterprises think about building software
• Balancing speed and agility with operational excellence
• Move fast - consistently and reliably
• Release fast and often
• Create business demand and customer value
• Enable high performing teams
• At scale, globally
This is what Cloud Native means

19. Deploying the world

20. Application workflow
$cf push demo-app
• to give
• demo.aws.my-pcf.com
• demo.vsphere.my-pcf.com
• demo.openstack.my-pcf.com
• cassandra.my-pcf.com

21. Connect to Cassandra

22. Connect App & Cassandra

23. Configuring Cassandra
On each Cluster
• Set the cluster names to all be Demo
• Seed nodes to include remote environments
• on every node
• Restarted clusters
Caveat: I did this behind the scenes

24. Global Load Balancing
• Such as Akamai
• Global
• Geo routing
• Register cassandra.my-pcf.com and point to all
three sites

28. here’s what it would have
demonstrated
• $nodetool status
• write data directly to one DC
• see it appear in another DC
• A failed site - everything is still ok!

33. Multi-Tenant plan
• Access to a shared 4 node
cluster on-demand
• Ability to scale vertically as you
require through OpsManager
• Great for development / testing
• Automated upgrades between
versions of Cassandra
• Using DataStax Enterprise &
OpsCenter
• Best practice configuration

34. Single-Tenant plan
• Production ready plan
• Access to a dedicated 6 node
cluster on-demand
• Ability to scale vertically as you
require through OpsManager
• Automated upgrades between
versions of Cassandra
• Using DataStax Enterprise &
OpsCenter
• Best practice configuration

35. @ben_laplanche

Multi-Tenant plan with upgrades &
Single-Tenant production plan
available in Q4
