Cloud Concepts


Cloud Computing by Stephen Fry

Summary of Cloud features

● Utility.

● On demand.

● The amount I need.

● When I need it.

● Pay only for resources used.

● Scale up and down according to demand.

11

Electricity went from customized and differentiated…

12

To standardized and commoditized

with economiesof scale

14

“...a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

- National Institute of Standards & Technology (NIST)

A different kind of architecture...

TRADITIONAL WORKLOADS

● Stateful virtual machines

● Big VMs: vCPU, vRAM, local storage inside VM

● Application SLA aligned to VM itself

● Relies on underlying HA technology to meet SLA goals

● VMs scale up: add vCPU, vRAM, etc.

● Applications not designed to tolerate failure of VMs

CLOUD WORKLOADS

● Stateless VMs, application distributed

● Small VMs: vCPU, vRAM, storage separate

● Application SLA not dependent on any one VM

● Many instances can provide application availability

● Applications scale out: add more VMs

● Applications designed to tolerate failure of VMs

Which workload type suits the customers requirements?

Analogy: Pets vs. farm animals

PETS =TRADITIONAL WORKLOADS

FARM ANIMALS =

CLOUD WORKLOADS

Credit : Tim Bell @ CERN Labs, Bill Baker @ Microsoft, and others

Pets are given names like

rover.internal.redhat.com They are unique, lovingly

hand raised and cared for When they get ill you nurse

them back to health

Farm animals have tag numbers like piggie242.redhat.com

They are almost identical to each other

When they get ill you get another one

Manufacturing as a Model for ITConsolidated Aircraft B-24 Liberator

Incredibly sophisticated. ~500k parts, assembled by unskilled labor.

No Mfg process. Parts were cast in rubber molds, so every part was slightly diferent.

Assembled in the heat of San Diego, which warped the metal and required whole assemblies to be adjusted.

Ford Motor Co. brought a Manufacturing process … went from 250 planes a year to 650 planes a month.

THIS IS OUR CHALLENGE TODAY.


Red Hat Enterprise Linux

OpenStack Platform


What's the big deal ?


OpenStack Components

● Needs to access x86 hardware resources● Runs on Linux and requires access to existing technologies

● e.g. a hypervisor, some storage and networking● Completely written in Python (yay!)


OpenStack design


OpenStack Architecture


Common OpenStack Architecture

● All data is held in a SQL database

● Can be made highly-available if replicated

● Default is MySQL, but others are supported

● Components have two sub-component types:

● API Endpoints – The RESTful entry-point into the component

● One or more 'daemons' – The services that carry out instructions

● Vast majority of OpenStack is shared-nothing and very fault-tolerant

● Components scale out using shared message bus (qpid, RabbitMQ etc)

● API Endpoints can be load-balanced (virtual IP's) for resilience/throughput


Typical Deployment


Why does the world need OpenStack?

● Cloud is widely seen as the next-generation IT delivery model

● Agile & flexible

● Utility-based on-demand consumption

● Self-service drives down overhead and maintenance

● Public clouds setting the benchmark, organisations want the same level of functionality but behind the firewall

● Not all organisations are ready for public cloud

● Applications are being built differently today-

● More tolerant of failure

● Make use of scale-out elastic architectures

● OpenStack enables organisations to achieve this, today... and without lock-in.


OpenStack distributions

● RackSpace

● Debian, Ubuntu

● OpenSUSE, SUSE

● Mirantis

● DevStack

● RHEL, Fedora, RDO

mirroring community● No certification, no support● Installs on Red Hat and

derivatives

● Open source, community-developed (upstream) software

● Founded by Rackspace Hosting and NASA

● Managed by the OpenStack Foundation

● Vibrant group of developers collaborating on open source cloud infrastructure

● Software distributed under the Apache 2.0 license

● No certifications, no support
