7 Steps to Enterprise

Cloud “Heaven”

3 approaches to on-prem IaaS

CLOUD (APPS)

SERVICE PROVIDER

APPROACH

IaaS

© 2013 Eucalyptus Systems, Inc.

The Apps Perspective:

Services are the Infrastructure

• IaaS is really backwards

– Infrastructure is really an application component

• Resources are really API and QoS

– No idea “what” hardware is actually being used

• Cloud platform is the unifying framework

– The services interact to provide complete infrastructure functionality regardless of underlying hardware

• Users, applications, operating systems, and data sets “touch” only the services

– Hardware becomes peripheral and interchangable

Step 1 – Understand the

Application Workload

• Application workload characteristics

– Cloud abstractions

• Compute

• Network

• Storage

• Identity

– Deployment requirements for the application

• Reliability

• Load balance

• Geographic distribution (e.g. regulatory)

Step 2 – Understand

Application Governance

• Who owns the application workload?

– Different than who owns the code

• Must design a way for the cloud administrators to “see” what the application is doing and to “talk” to the workload owners

• Software ecosystem

Step 3 – Design the Physical

Deployment

• The cloud is a control plane

– Once the apps are running, the cloud is out of the “way”

• Imagine, after the apps are deployed, that the cloud control plane vanishes for an instant

– Will the apps survive?

• VM capacities, network design, storage requirements

Step 4 – Design the Cloud

Deployment

• Private cloud is a scalable service venue

– Many cooperating service components requiring network, storage, and compute

• High-availability and redundancy

• Traffic planning

• Memory requirements for cloud components

Step 5 – Test everything and

then test it again

• Figure or merit testing should be worst case

– Test failures

– Test upgrade

– Test failures during upgrade

– Test upgrade during failures

• Observe the testing results from the application perspective

– What does the application experience if the cloud is degraded?

Step 6 – Integrate cloud with

existing management policies

• The cloud is a new platform

– Not a set of independent tools

• Capacity planning

• HW budgeting

• Racking

• Identity management and security

• Coordination of scheduled down time

– Who gets called?

Step 7 – Lifecycle planning

• Plan to build incrementally

• Plan to hybrid incrementally

– Internal: Cloud and non-cloud components need to interact in the data center

– External: Enterprise cloud and public clouds

• Plan to sunset incrementally

Eucalyptus

• Elastic Utility Computing Architecture Linking Your Programs To Useful Systems

• Web services based implementation of elastic/utility/cloud computing infrastructure

– Linux image hosting ala Amazon

• How do we know if it is a cloud?

– Try and emulate an existing cloud: Amazon AWS

• Functions as a software overlay

– Existing installation need not be altered

• Open Source

– Built from best-of-breed Open Source technologies for eCommerce
