How to choose your cloud?• PaaS vs. IaaS - Both great options, but what works for you?

CriteriaPaaS

(Azure)

IaaS(EC2, Rackspace, Private Cloud, …)

Do you need to use custom software? No Yes

Do you need to manage network traffic? No Yes

Do you have legacy systems? No Yes

Are you planning on leveraging the PaaS built-in services

(SQL Azure, App Fabric, etc.)?Yes No

Challenges in the Cloud

• Images and their contents• Lack of standardization and consistency across versions, regions and

clouds• No software license management• Often do not follow best practices• By design, open to security vulnerabilities

• Pre-install required software and applications• Custom configuration in “baked” images• Long development iterations

• Lack of Automation• Trust relationships hard-coded• No automated orchestration (How do I set up my application?)

RightImages in the Cloud• Images and their contents

• RightScale RightImages

MVP >

• RightImages are optimized for performance and security• RightImages all contain:

• RightLink• Powershell 2.0• .NET Framework 3.5/4.0• Critical Windows Updates• Application Service Packs• Windows Install Media for Windows Server 2003

• RightImages serve as a secure reusable base from which you create automated configuration and orchestration

Images vs. RightScale ServerTemplates

• Big & opaque• Complex to reproduce• Static• Not cloud-portable

Slow workflow Not cloud-agile

• Modular & flexible• Reproducible &

maintainable• Dynamic & agile• w/ MCI - Multi-cloud enabled

Dev-like workflow Dynamic configuration

ServerTemplates: A Closer Look

• Starts with a multicloud image• Defines base software

• Adds:• Boot, operational and decommission RightScripts and/or recipes for

configuration• Monitoring with alert definitions for automation

• ServerTemplates are versioned• Reproduce exact configuration

• ServerTemplates can be published/imported• Sharing / reuse

How does this all work?

RightScaleSecure and Fault-Tolerant Protocol

RightLink runs with Admin privileges on the Server and talks to RightScale through a secure and fault-tolerant protocol.

RightLink Deep Dive

• Open-Source Agent• Installer is available to RightLink-enable your images

• Functions• Receive commands from RightScale

• Runs RightScripts on the local instance• Can identify itself and other servers using tags and take

actions based on that• Delegate actions to RightScale management via internal API

• Secure• Signed & encrypted AMQP transport• Scoped to the Deployment

Automated Configuration - RightScale

• Best Practice configuration for network security and isolation• Pre-configured Monitoring and Alerts (cpu, memory, disk)

• Create custom monitors as well• Faster boot times with performance enhancements

• Reduced number of reboots when launching a server• Reliable Volume Management

• Guarantee that a volume attaches as predefined drive letter every time

• Advanced Snapshot capability using Microsoft Volume Shadow Services• Reliable and fast backup mechanism with restore

capabilities
