DATA CENTER WORKLOAD TRENDS

Changes in Data Center WorkloadsMoving from homogeneous workloads to heterogeneous• Yay! More workloads means more goals achieved

• Ohh… How to manage the infrastructure of all these workloads

Moving from ticket/request based systems to self-service portals• Yay! Users provision themselves!

• Ohh… Need to pick/maintain self-service portals

Microservices instead of 3-tierd Applications• Yay! Allows for rapid development, deployment, iteration!

• Ohh… Requires much more agile deployments than traditional virtualization/IT currently provides

Advent of OpenStack• Yay! Open source cloud operating system!

• Ohh… Very difficult to deploy from source.

Traditional Virtualization: Applications!

Application

Applications have traditionally

been tightly coupled with the

server they were installed on.

With the advent of virtualization, this

paradigm had not changed.

Applications were tightly coupled with

the VM they were installed on.

Application

Pets Versus Cattle

Traditional VM Cloud Instance

Pet Cattle

Lives Forever Terminated frequently

Persistent storage Storage disappears when instance

terminated

OS Installed manually or cloned Instantiated from image

Based on ISO installation CD Based on pre-created image

Very individualized Tied to limited number of images

Developing for Redshirts

Cloud Applications: ResilientApplication

shard

shard

shardshard

• Applications are written

so that their load is

easily self-distributed

(referred often as

Sharding… that’s with a

“d”)

• Applications are

generally stateless. The

loss of any instance or

node results in no

service disruption or

data loss

Cloud Applications

• Cloud Apps generally don’t

need vMotion/Live Migration,

they were made to be run on

“redshirt” instances

• Instances can be removed

without disruption to the

application

• Applications generally go for

“eventual consistency”, rather

than immediate consistency

Not again!

Starfleet is not

going to be

happy…

OPENSTACK

What Is OpenStack?

“OpenStack is a cloud operating system that controls large pools of compute,

storage, and networking resources throughout a datacenter, all managed

through a dashboard that gives administrators control while empowering their

users to provision resources through a web interface.” –Openstack.org

Basics of OpenStack

An Open Sourced platform

(Apache 2.0 License)

Comprised of a collection of

“programs” responsible for

various aspects

Functionality is abstracted at

the program level, details

handled locally

Consumed via API/GUI/CLI

OpenStack Heat Orchestration

• Heat is an automation tool that

launches multiple resources to

create all the facets of a given

application

• Meant to be compatible with AWS

CloudFormation template format

• Heat can automatically instantiate

images and customize them,

instantiate network and storage

resources, auto-scale in/out, and

more

• Integration with Chef and Puppet

UCS AND OPENSTACK

Cisco UCS

• Stateless computing

• Service Profile-based

management

• CLI, API, or GUI interaction

Cisco UCS Stateless Computing for

Dynamic Datacenter Workloads

• Cisco UCS stateless computing

leverages service profiles to easily

change between workloads

OpenStack is a great platform for operating your private

cloud, but…

You need to pick a distribution. Like Linux, OpenStack exists

mostly as various distributions
