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?


THE POWER OF THE CLOUD

Programmatically accessible infrastructure


INFRASTRUCTURE ON DEMAND

Deploy infrastructure when you need it


INFRASTRUCTURE ON DEMAND

Turn it off when you don’t need it


MATCH COST TO DEMAND

Shrink the gap with automation


DEMAND PATTERNS


HYBRID-CLOUD STRATEGIES

Own the base. Rent the

peak.

A NEW WAY OF THINKING

Virtualization is a TECHNOLOGY…

Cloud Computing is a BUSINESS MODEL


WHY IS A MANDATE FOR DEV/OPS IMPORTANT?

Dev + Ops On the same train

Increased Collaboration

Smarter Applications

Faster Time to Market


IT DEV/OPS TRANSFORMATION

Communication… Collaboration… Integration

Dev/Ops Org Structure is Driven by Cloud Adoption

Operations: Deeper Application Knowledge

Developers: Understands Code Impacts Infrastructure


DESIGNING APPLICATIONS FOR THE CLOUD

• Built for Resilience & Error Tolerance

• Loosely Coupled Components

• Preserved & Recoverable Application State

•Self monitoring, healing and scaling

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-486451d3ca74 App$i; done

/dev/vdb nova volume-list


CLOUD CONTROL PANEL – CLOUD LOAD BALANCERS

5) Deploy a public cloud load balancer for HTTP traffic









6) Deploy a private cloud load balancer for internal TCP traffic








CLOUD CONTROL PANEL – CLOUD DATABASES

7) Deploy a MySQL database










CLOUD CONTROL PANEL – CLOUD SERVER IMAGES

8) Create “Gold” server images






APPLICATION PROGRAMMING INTERFACE – FILES

7) Push a file to Cloud Files and enable it over the Akamai CDN

Upload File to Container curl -X PUT -T screenies/hello.jpg -D - \ -H "ETag: 805120e285a7ed28f74024422fe3594" \ -H "Content-Type: image/jpeg" \ -H "X-Auth-Token: fc81aaa6-98a1-9ab0-94ba-aba9a89aa9ae" \ -H "X-Object-Meta-Screenie: Hello World" \ https://storage.clouddrive.com/v1/CF_xer7_343/ images/hello.jpg HTTP/1.1 201 Created Date: Thu, 09 July 2009 17:03:36 GMT Server: Apache Content-Length: 0 ETag: 805120e285a7ed28f74024422fe3594 Content-Type: text/plain
