BE A CLOUD NATIVE
Which workload do I put in the cloud?
Application changes?
What is DevOps?
Should I think about lock-in?
Is my data safe?
Where do I start?

EXAMPLE DEPLOYMENT DIAGRAM

EXAMPLE DEPLOYMENT PROCESS OVERVIEW
Tools:
• Nova Command Line Tool (CLI)
• Rackspace Cloud Control Panel (Control Panel)
• Application Programming Interface (API)
Today’s steps:
1) Create a Private Cloud Network (CLI)
2) Deploy 6x 2GB Cloud Web Servers (CLI)
3) Deploy 4x 4GB Cloud App Servers (CLI)
4) Add SSD Block Storage to the App Servers (CLI)
5) Create a public Web Load Balancer (Control Panel)
6) Create a private App Load Balancer (Control Panel)
7) Create MySQL Database Instance (Control Panel)
8) Create Gold Images (Control Panel)
9) Push a static file to Cloud Files for CDN (API)

NOVA COMMAND LINE – CLOUD NETWORKS
1) Create a private cloud network
nova network-create PrivateNet 192.168.0.0/24

NOVA COMMAND LINE – CLOUD SERVERS
nova image-list
nova flavor-list

• nova image-list (Copy desired Image-ID)
• nova flavor-list (Copy desired Flavor-ID)
• nova network-list (Copy desired Network-ID)
2) Deploy six 2GB Ubuntu 12.04 Web Servers sharing PrivateNet
for i in `seq 1 6` ; do nova boot --image 5cebb13a-f783-4f8c-8058-
c4182c724ccd --flavor 4 --nic net-id=b771c94e-5cfe-43c1-a8be-
486451d3ca74 Web$i; done
3) Deploy four 4GB Ubuntu 12.04 App Servers sharing PrivateNet
for i in `seq 1 4` ; do nova boot --image 5cebb13a-f783-4f8c-8058-
c4182c724ccd --flavor 5 --nic net-id=b771c94e-5cfe-43c1-a8be-
