ABOUT THE AUTHOR

Cutting through the hype: Cloud differs from the

traditional approach to outsourcing– On demand provisioning– Pay as you go – pay as

you grow– Much lower cost as

economies of scale are assumed

– Near infinite capacity Cloud is not virtualisation Cloud is not finance / off

balance sheet financing


WHAT ISCLOUD?

What should it be about: The ability for

organisations to stop solving all IT problems by themselves

It’s not just about sharing resources

It’s about pushing risk out of the business

If I took every component of what we use in our data centres and provided it as a service…

…it would not be cloud


WHAT ISCLOUD?

Cloud Rep v Enterprise CIOHow much Cloud do you want to buy ? We have scale and can easily migrate your user base You can move from Capex to Opex Look at how much we do Look how big our data centre is


Cloud Rep v Enterprise CIO Flash Migrations are Utopian You don’t need to decommission all your IT assets One vendor will never have all the answers Why you can’t trust your ISP


Cloud Rep v Enterprise CIO Part 2(I see you’re informed…)

How much Private Cloud do you want to buy? We manage thousands of virtual servers and can build you your own pod Private Cloud solves the customisation limitations of Public Cloud The infrastructure is dedicated to you


Cloud Rep v Enterprise CIO Part 2

How much will you really lower your costs by substituting your existing enterprise tools? Private Cloud has structural Rules as well Dedicated Infrastructure does not a Private Cloud make Your line of business personnel may not have the expertise for self-service


The Answer =


Hybrid

Lesson 1

STAY AGILE You need an orchestration

layer that is vendor agnostic

API’s are meaningless if they are tied exclusively to Private Cloud or a particular public cloud

Lesson 2

EMBRACEMULTI-TENANY Hierarchical domains are

too rigid Think of your

infrastructure as ‘Pods’ – Some Pods will be

existing infrastructure– Some will be offsite

Private Clouds– Some will be Public

Clouds


Lesson 3

GOVERNANCE IS KEY Audit everything Encrypt wherever possible Geographical Legal Regimes

affected where you host


Lesson 4

USE ABLENDER Pick and choose from Public

& Private Cloud to create the perfect cocktail

Don’t run an open bar– Make sure you can apply

chargebacks


Lesson 5

THE NETWORKCOUNTS Assume you may need to

run disconnected Head Office is now a point

of failure Learn to use ThinApps


Email & Messaging Bring your own Client Access

License Filtering and Archiving are

low hanging fruit Use a Public Cloud for

Exchange– Beware of Email Branding

Leverage Intelligent routing for flexibility in mergers and acquisitions


PUTTING IT ALL TOGETHER

Continuous Data Protection Repurpose your out of

maintenance SANs for onsite backup

Replicate Data to a public cloud vendor– But keep the encryption

keys Backup Laptops directly to

the cloud



Remote Monitoring & Management Add Hosted Remote

Monitoring & Management tools to your service desk– Directory integration is

no longer a constraint Turn your IT department

into a managed service provider



Private Cloud Restore your backup to a

hosted offsite Private Cloud Find a vendor who can

manage your existing hardware as a Pod
