What is Cloud Economics

The Myths of Cloud Computing

Variables and Cost Models

Resources

Principles of Cloud Economics

IT as a Utility - Available and Scalable

IT is Paid for using a Consumption based model

Theoretically 100% capital efficient

Capacity is CapEx and Cyclically Driven

Usage follows predictable patterns

Cost increases with time and complexity

IT Cost Model

Capacity scales up and down in line with demand

Usage follows predictable patterns (no change)

Cost matches capacity - pay as you consume

Cloud Cost Model (Theory)

Capacity is provisioned based on expected load

Usage follows predictable patterns

Cost goes up and to the right, with an **** moment

IT Cloud Cost Model (Actual)

Cloud Economics Reality

The Cloud is not analogous to the Electricity model.

The Cloud is not Pay as You Go. It’s Pay as You Provision.

Utilisation is the problem -> the traditional capacity planning model has migrated to the Cloud.

• Physical Hardware - 20% Utilisation Average• Virtualised Infrastructure - 30% Utilisation Average • Cloud Deployments - 30% Utilisation Average

IT / the Cloud isn’t inefficient

You are

Traditional Culture

IT has never been responsible for Cost metering

Budgets are aspirational targets

Existing tools focus on Uptime, Usage and Performance Monitoring

Efficient Computing

You can’t manage what you don’t measure

Create Accountability, Visibility, Reporting

Meter Cost, Capacity and Usage

Myths

Myth # 1Cloud is Cheap

Like for Like - More Expensive

But it’s not Like-for-Like

• Scalability & Flexibility

• Resilience & Redundancy

• OpEx not CapEx

More Cost Effective for a lot of workloads

Truth

Myth # 2The Cloud is

Cheaper than DIY

Versus Fully Loaded Server Cost - True 90% of time

Do you know the true costs of your IT infrastructure?

Cloud often ‘looks’ more expensive but is not.

Netflix vs Zynga models -> both right

Truth

Myth # 3Pay for What You Use

Pay for What you Provision

Truth

Myth # 4“I can migrate easily”

Data IN is FREE

Data OUT is NOT. For a reason.

Data Gravity : Data attracts more Data

More Data = More Costly to Move

Truth

Myth # 5The Cloud is Managed

Cloud Providers manage their Cloud

Not Yours

Ops is going Nowhere

Truth

Myth # 7Cloud is more Efficient

Jevon's Paradox : The easier it becomes to consume a resource, the more of it that will be consumed.

The Cloud has enormous efficiency capabilities.

Waste is not a technology problem, it’s a people one.
