2 Introduction! u Community pgadmin lead developer! PostgreSQL core team member! Installer maintainer! Postgres Europe and Postgres Canada board member! u EnterpriseDB Chief Architect, Tools & Installers! Infrastructure lead! 2

3 What is a Cloud Database?! u Database taking advantage of a cloud environment Point and click deployment! Point and click management! Auto and manual scaling! Auto healing! u Not merely "installed" in the cloud Which would require similar administration to a physical machine.! 3

4 What is PPCD?! u Cloud database: Multi-platform:! Amazon AWS! HP Cloud (OpenStack)! Citrix (CloudStack)! More coming soon! Multi-server:! PostgreSQL 9.1/9.2! Postgres Plus Advanced Server 9.1/9.2! 4

5 Features! u Web based management u Data security u Horizontal and vertical scaling u Storage scaling u Self-healing u Extensible 5

6 Architecture! 6

7 Web based management! u Deploy new database clusters with a simple wizard u Perform manual maintenance with a few clicks: Add replicas and clones! Perform backups! Upgrade clusters! Performance monitoring! 7

8 Live Demo Create a new cluster! 8

9 Data security - replicas! u Clusters contain one or more replicas of your data u Uses streaming replication u Replicas are used for read load balancing u Replicas can be promoted to the master role at any time 9

10 Data security - clones! u Clone a cluster at any time u Useful for: "online" backups! Reporting clusters! Development clusters! 10

11 Data security - backups! u Automated backups to storage such as S3 u Manual on-demand backups u Restore to a new cluster on demand 11

12 Live Demo Run a backup! 12

13 Horizontal scaling! u Scales out by adding more nodes to the load balanced cluster u Manual scaling on demand u Auto-scaling based on "read" connection numbers u Can be performed live 13

14 Horizontal scaling how?! u Snapshot the data directory u Initialise a new server instance u Create a data directory from the snapshot u Add the new instance to the cluster and "catch up u Add the new instance to the load balancer 14

15 Live Demo Add a replica! 15

16 Vertical scaling! u Scales up (or down) by changing the machine type u Manually initiated only u Currently requires a maintenance window 16

17 Vertical scaling how?! u Snapshot the current cluster u Duplicates cluster servers onto new machine types u Restores backup taken in step 1 to all nodes u Starts the databases and replication u Optionally switches the elastic IP over to the new cluster 17

18 Storage scaling! u Manual scaling of storage u Automatic scaling when at N% used u Can be performed live 18

19 Storage scaling how?! u New EBS volumes are created for each node u New volumes are mounted and added to the data volume group u Logical volume expanded to utilise additional space 19

20 Live Demo Auto scaling! 20

21 Self healing! u Automatic replacement of failed replicas u Automatic replacement of failed masters: Promotes then replaces an existing replica OR! Creates a new master and brings it online! 21

22 Extensible! u Shell access to cluster nodes u Allows installation of extensions like PostGIS u Push configuration changes to the pooler and database servers from the console 22
