The New DevOps Designers: Cloud and The Big Rethink

Cloud and The Big Rethink

The Wisdom of Clouds

InInformation Technology,
You’re Either “In”, or You’re “Out”

Client-Server
is “out”.
Kind of like IT spats.

Data Centers
Are Boring.
The “t-shirts” of IT

Virtualization
is the New Black.
Going “old-school”…

Cloud
is “Hot, Hot, Hot”.
Everybody’s doing it!

The problem is…
This is IT Operations

Operations?
The Reality
The Fantasy

management, envisioning, planning, design, implementation, construction, deployment, distribution, verification, installation, instantiation, execution and maintenance

Virtualization
changed everything.
And nothing.

So what about cloud?

Cloud
changes everything.
And nothing.

Up until now, IT has worked from a server centric operations model.

Cloud is an application centric operations model.

What does that mean?

Prior to cloud, we were server centric…

OS
Live motion shifted us to
VM focus
VM
VM
VM
Started with
server focus

We measured:
CPU utilization
Memory utilization
I/O utilization
We bought:
CPU
Memory
Storage
Bandwidth
This required:
Management
Planning
Design
Implementation
Construction
Deployment
Distribution
Verification
Installation
Instantiation
Execution
Maintenance

With the adoption of cloud, we are now application centric…

Application
Cloud
Code

Policy
Virtual Resources
Other Services
Someone else’s stuff

Need Evidence?

We measure:
Scale
Health
Performance
We rent:
Compute
Storage
Bandwidth
Platform
Service Level Assurance
Security/Compliance
This requires:
Management
Planning
Design
Automation
Maintenance

Application
Apps don’t need general purpose machines or OSes
Code
Code
Data
Policy
Other Services
Virtual Resources
Someone else’s stuff

Applications don’t need machines. They don’t need operating systems.
But they do need new operations designs.

That’s what you are here to learn about today.

Installation, Configuration, Reliability, Performance, Security, Metrics, Provisioning, Analysis, Auditing, Availability, Adjustments, Learning, Standardization, Compliance, Healing, Balancing,
Conflict Resolution, …

Operate
