Which do you use and how to use both

OPENSTACK OR AMAZON WEB SERVICES

2 ADD NAME (View > Master > Slide master)

Agenda● Compare services that the two platforms provide● Compare business characteristics of AWS & OpenStack● How to choose a platform?● How to use both environments?

Product demonstrations!● This session focuses on business problems, strategies and solutions

and is not a technical deep dive.


What is OpenStack● A cloud operating system that controls large pools of compute,

storage, and networking resources● Managed through a dashboard or command line ● Empowers users to self provision using a GUI or CLI


What is AWS● Provides a way to access servers, storage, databases and a

broad set of application services over the Internet. ● Amazon Web Services own and maintain the network-connected

hardware required for these application services,● You provision and use what you need

COMPARISON OF SERVICES


ComputeDefinition

● Virtual machine(VM)/instance with memory, CPU and storage.● The size of an VM/instance is determined by a template/flavor.

Why you need it?● To run an application you need a server with CPU, memory and

storage. ● Instances/VMs with pre-installed operating systems (and

applications).

NetworkingDefinition● Provides access for users to virtual machines● Connects virtual machines to one another, and to

external networks and the Internet.

Why you need it● To network virtual servers to each other.● To manage network services, IP address ranges etc


Networking OpenStack AWS

Name Neutron NetworkingOffering IP addressing

Load BalancingFirewall(DNS)

StorageDefinition● Block storage to create virtual disk drives(volumes). ● Object storage to store objects such as files, media,

images etc

Why you need it?● Assign virtual volumes to virtual servers & for

snapshots and backups of virtual servers.● Store objects or VM images

Identity/securityDefinition

● Authenticate and authorize users.● Control access to your virtual machines/instances.

Why you need it?● Firewall virtual machines to only allow certain traffic

in (ingress) or out (egress).● Authentication and authorization methods for

controlling access to cloud resources.


Identity / security

OpenStack AWS

Keystone - authentication, roles, privileges.

IAM - authentication, roles, privileges.

Virtual firewall Virtual firewall


OrchestrationDefinition● Allows developers to store the requirements of a cloud

application in a file.● What resources (virtual machines, networks, storage,

security, templates, images etc) are necessary for the application to run.

Why you need it?● This allows repeatable operations to be executed.


OrchestrationOpenStack AWS

Name HEAT CloudFormation

Method Text files for repeatable operations

Templates for repeatable operations


User interface and APIsDefinition● CLI: Command Line Interface provides administrators with

commands provision and de-provision cloud resources.● GUI: Graphical User Interface provides administrators with a web

interface to provision and de-provision cloud resources. ● API: Application Programming Interface to allow programmatic

automation to provision and de-provision cloud resources.

Why you need it?● Administrators manage cloud resources.● Users to self-service their needs for compute power.

BUSINESS CHARACTERISTICS


SLADefinition● An SLA is a guarantee of availability of the cloud.

Why you need it?● To run mission critical applications with minimal

downtime you need an SLA from your cloud provider.


SLA OpenStack AWS

SLA offeringSupport from your OpenStack team.

(Red Hat offers 24x7 support, security, consulting. Can

achieve “five 9s”)

99.95%

High Availability Availability Zones Availability Zones

Ownership of dataDefinition● When you store applications and data in the cloud who owns

the data and who has access to it.

Why you need to know?● Users should know who can access data stored in the cloud.● Legal regulations for industries ● Concern that USA government security agencies demand

access to public cloud data.


DataOpenStack AWS

Who owns your data You You

Who controls your data You

You but...AWS SLA




EcosystemDefinition● An ecosystem includes vendors and consultants

vendors, that enable a cloud to run.

Why you need to know?● Reliable.● Secure.● Supported.● A network of peers you can use for assistance.


EcosystemOpenStack AWS

You are not alone

Partners who offer● Operating

Systems● Applications● Add-ons● Consulting● Developer

support● Hardware● Community

Partners who offer● Operating Systems● Applications● Add-ons● Consulting● Developer support


Cost

Definition● The cost of using a cloud service.

Why you need to know?● Costs can be operational (OPEX) or capital (CAPEX).


Pricing OpenStack AWS

Cost● Purchase

hardware and software

● Receive support, maintenance, consulting

● Or “DIY”

● Credit card billing by the minute/hour

● Pre-purchase blocks of usage at other rates


WHICH DO YOU USE?


OpenStack or AWS?● Cost

● Can rapidly escalate in public cloud● To maintain a private cloud

● Personnel & capacity● Security or regulatory

● Requirements vary by industry and country● SOX, HIPAA, PCI-DSS, FedRAMP, FIPS, ISO 27001

● Use cases


Use casesLocation of your customers - Worldwide or Localized

Development – Platform-as-a-Service

Elastic workloads - Demand grows and shrinks.

High performance computing – high perf. IOPS

Dedicated resources / segregation

Hybrid - OpenStack in co-located DC with burst


Hybrid: How do you manage OPENSTACK & AWS


A cloud management platform

How to use both – an open hybrid cloud – a combination of private and public clouds
