Cloud Computing
On-demand
•
Pay-as-you-go
•
Virtually infinite
•
Surpasses traditional hosting
•
Multiple server sizes: ½ core to 8 cores
–
Reassign IPs / VIPs
–
Multiple failure zones and geographies
–
Disk Volumes
–
Cloud interoperability
–

Agile Deployment
• Agile = automate and benefit!
– From boot to production on auto-pilot
– Across different stacks & different clouds
– Auto-failover, auto-restart, auto-scale

Agile Development
Meets Agile Deployment

6

Next Generation Server Architecture
• “Cloud-ready” servers and clusters
– More than just running a bundled image
• Dynamic vs. static configuration
– Leverage one server model across different deployments
– Replicable design
– Complete lifecycle management … version control
• RightScale ServerTemplates
– Define the composition and configuration of your servers
– Like burning a CD from a Playlist

7

RightScale ServerTemplates
• Base OS image plus the intelligence to
run RightScripts
• Boot, Operational and Decommission
Scripts
– Configure instances during boot time including installing software and
passing environment variables
– Reconfiguration with Operational scripts
– Decommission scripts

• Library of RightScale and Partner
Templates or create your own

Key Benefits: Cloud-Ready Servers
✓ Save time and reduce complexity
- Dynamic configuration
✓ Portability
- Configure once, deploy multiple times
✓ Do more with less
- Complete lifecycle management

9

Sample Deployment

• 4-servers
– 2x load balancer/app servers
– 2x master/slave database

10

Auto Scaling
• Rules-based system
• More than just launching an instance
– Complete system architecture
– Auto configuration into cohesive resilient cluster
– Support for workflow and lifecycle management
• Addressing multiple business cases
– Load: Highly elastic web applications (e.g., Facebook app)
– Schedule: Event-based content sites
– Queue: Size and time in queue for batch processing needs

11

Scale-Out the App

• 2x front-ends
w/Elastic IPs
• 2+N app servers

Managing Cloud Deployments
Resources On Demand
•
More Automation
•
Less Administration
•
Full Control

17

Ongoing Management Tasks
• Migrate to larger instances
Demand Grows • Add more servers
• Set up dynamic arrays and auto-scaling

New Feature • Stage, Test
• Update application servers
Rollout
• Stage, Test
New System • Update servers
Software Versions

• Restart servers
Failures • Failover to new servers
• Failover to slave databases

Deployment Management
Traditional Way … Cloud Way …
When software needs to be When software needs
upgraded, risk in place to be upgraded, launch
upgrade and downtime or new servers with
purchase duplicate upgraded software;
hardware decommission old when
new environment
stabilizes

19

Deployment Management
Traditional Way … Cloud Way …
When database fails over to When database fails
slave, troubleshoot and over to slave, start up
fix master new slave
When database machine When database
needs to be upgraded, machine needs to be
either upgrade with no upgraded, launch new
redundancy or purchase servers; decommission
duplicate hardware; old when new
afterward redeploy or environment stabilizes
dispose of old hardware
