Today’s Focus

Survey:
Are you running databases in containers today?
1) For production (10.11%)
1) Development (22.74%)
1) No (67.15%)

Cattle and Pets
● Containers support an ephemeral and
fungible model
○ Need more? Make more!
○ Acting up? Replace it!
● Applications are fungible, like cattle - databases
are not
● Databases are
○ Persistent
○ Take a long time to warm up (cache loading)
○ When disconnected, they impact applications (disconnects,
transaction restarts, errors visible to the users, …)
● Treat databases lovingly - just like pets

12. © Copyright EnterpriseDB Corporation, 2019. All rights reserved.12
High Availability for Databases
● Things to consider
○ Do you need streaming replication with query routing, load balancing and/or read
scaling?
○ Do you need synchronous replication?
○ Double (triple?) check that the database container is really down (get consensus and
avoid false failover)
○ Promote carefully and make 100% sure that no application remains connected
(STONITH)
● Options:
○ Custom scripting
○ Stolon https://github.com/sorintlab/stolon
○ Patroni https://github.com/zalando/patroni/
○ EDB Failover Manager

13. © Copyright EnterpriseDB Corporation, 2019. All rights reserved.13
Survey:
How are you handling high availability in
database containers?
1) No HA (62.37%)
2) Stolon (1.55%)
3) Patroni (4.12%)
4) EDB Failover Manager (9.28%)
5) Other (22.68%)

EDB Container Strategy
● Containers are becoming a key database deployment platform
○ Current focus: Development, some production deployments
○ Expectation 2020: Major production deployment for EDB Postgres platform
● Database best practices for containers are emerging
● EDB supports
○ GKE
○ OpenShift
○ IBM Cloud Private
○ Pivotal Cloud Foundry (planned for H2 2019)
