Transcript of Oracle Infrastructure as a Service: Compute - exitas.be we chose IaaS-compute •Quickly available...
Case
• Customer from the utility sector
• Demo of patching with minimal downtime using Data Guard
• Remote accessible
• Strictly regulated environment
5/10/2017 3
Why we chose IaaS-compute
• Quickly available
• Low cost for short term
• Clean decommissioning
• Remotely accessible
• DBaaS not possible to demonstrate patching

What we wanted
• Two servers
• Enough storage , with snapshot capability
• Oracle database
• Data Guard setup
• Connection between servers
• Remote SSH access
• OS acces to Oracle binaries for patching

Approach : Steps
1. Create the first instance
2. Create and attach storage volumes
3. Setup connectivity and firewall rules
4. Prepare storage
5. Install Oracle
6. Setup Data Guard on a second instance
7. Perform demo
8. Cleanup the machines

Approach : Step 1 : Create Instance
• High Availility = Active
• Automatic restart of machine
• Storage must be reattached
• Generate key pair
• Required for ssh connections to the machine

Approach : Step 2 : Create and attach storage
• Wizard problem
• When to attach
• No shared storage

Approach : Step 3 : Setup connectivity and rules
• Create security rule
• Use SSH
• Connect as user opc
• Sudo su -

Approach : Step 4 : Prepare storage
• Storage volumes:
Create a partition
Make a filesystem
Mount it
Just like a physical server

Approach : Step 6 : Setup Data Guard
• Just like on physical servers
• Create via RMAN duplicate
rman TARGET SYS/du@mydb AUXILIARY SYS/du@mystandby
DUPLICATE TARGET DATABASE FOR STANDBY … ;

Approach : Step 7 : Perform demo
Create snapshot
Use for resetting environment, between test-runs
Very convenient

Approach : Step 8 : Cleanup the machines
• Instance vs master orchestration
• Snapshots vs backup

Summary• Some time required to become familiar with the concepts
• Setup of a vm: hours to minutes
• Pro :
• Flexible and quick deployment
• Similar to physical machines for application installation
• Low cost : our complete environment 4 euros/day
• Clear cost status

Summary
5/10/2017 22
• Contra :
• Some bugs in web interface
• Slow orchestration
• Network config takes puzzling
• Support and assistence slow response
• Overall feeling:
• Satisfied with the choice for the Cloud
• We will certainly use it again
Quality. Passion. Personality.
