Presenter: Ben Laplanche, Product Manager, Pivotal Cloud Foundry 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 center, 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 walkthrough of the key concepts, approaches, and considerations.

Building A Diverse Geo-Architecture For Cloud Native Applications In One Day
- 1. Building a diverse geo- architecture for Cloud Native Applications in one day Ben Laplanche Product Manager - Pivotal Cloud Foundry
- 2. Who am i? • Ben Laplanche • Product Manager on Pivotal Cloud Foundry • Based in London • Focused on services & partner enablement • @ben_laplanche • blaplanche@pivotal.io
- 3. @ben_laplanche “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
- 9. @ben_laplanche But what about global reach and resiliency?
- 12. @ben_laplanche What did I deploy?1. Full Pivotal Cloud Foundry 1. Runtime & container orchestration 2. Logging & metrics 3. Health monitoring 4. Application auto scaling 2. DataStax Enterprise 1. 6 node cluster 2. DataStax OpsCenter 3. VPN Tunnel To each location

- 16. Network view continued… AWS Environment Apps domain *.aws.my-pcf.com Public subnet CIDR 10.0.0.0/24 Private subnet CIDR 10.0.16.0/20 Cloud Foundry range 10.0.16.1 to 10.0.16.49 Datastax range 10.0.16.50 to 10.0.16.55
- 18. IaaS Setup AWS vSphere Openstack • Cloud Formation scripts • VPC • Subnets • Security Groups • RDS • S3 • ELBs • vCenter • Resource pools • Networking • Disk • DNS • Openstack Tenant • Physical hardware • Floating IPs • DNS • Permissions
- 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
- 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
- 26.

- 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!
- 29. @ben_laplanche Doing this, but better
- 30. TCP Router PrivatePublic Pivotal OpsManager Load Balancer C* C* C* C* C* Cassandra node WWW HTTP Router DEAs TCP Router
- 31. Arbitrary Params Specify configuration when creating a single-tenant instance $cf cs p-datastax single-tenant demo -p “{cluster_name”: “demo”, “remote_seed”: “cassandra.aws.my-pcf.com”}
- 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 Available from http://network.pivotal.io Multi-Tenant plan with upgrades & Single-Tenant production plan available in Q4
- 36. Any questions?
