Agenda

The Cloud Landscape

● Infrastructure-as-a-Service (IaaS)

● Platform-as-a-Service (PaaS)

● Software-as-a-Service (SaaS)

The Cloud Landscape

Why cloud?

Because cloud enables self-service resource provisioning, it gets your developers productive faster and reduces time-to-market for application development -- and progress.

The Cloud Landscape

What is OpenStack?

Public Cloud vs Private Cloud

Public cloud

A public cloud is ...

A collection of cloud resources accessible in a general pool shared with other customers and maintained by the public cloud provider.

Public Cloud

Advantages1. No initial outlay2. Instantly available3. No management concerns4. Various services (depending on the provider)

Public Cloud

Disadvantages1. No centralized budget control2. No cost control3. Data security concerns4. Data privacy concerns

Private cloud

A private cloud is ...

A collection of cloud resources accessible in a general pool but kept within a single company, either on premise or serviced by an external company but isolated from other customer workloads.

Private Cloud

Advantages1. Centralized budget control2. Data control3. Architecture control4. Access to legacy systems

Private Cloud

Disadvantages1. Capacity limited by capital outlay2. Inhouse maintenance requirements3. Disaster recovery concerns

Hybrid Cloud

Hybrid cloud

A hybrid cloud is ...

... a collection of resources that may exist in different cloud structures. Most often, some of these resources are on premises for an organization, and some are not. Workloads can pass between these two (or more) sets of resources.

Hybrid Cloud

Use cases1. Dev/Test in the cloud2. Alternate location for backup/disaster

recovery3. Load bursting

Hybrid Cloud

Horizontal bursting1. Apps and data begin internally.2. Systems burst to public clouds when

necessary.3. Loads recede to internal systems when

possible.

Hybrid Cloud

Vertical bursting1. Apps are manually placed based on type.2. Dev/test placed on external cloud until the

app is ready to be blessed.3. Mission/business critical data/apps kept

internal.

Hybrid Cloud approaches

Datacenter as a Service● Hosted externally● Still isolated

Hybrid Cloud approaches

Homogenous cloud● All OpenStack● All the same APIs

How it works at Rackspace

Hybrid Cloud approaches

Heterogeneous cloud● Any type of cloud ● Any other type of cloud

Summary

● Cloud consists of several layers● OpenStack is open source cloud● Public cloud vs private cloud● How hybrid cloud is about expanding capacity● Hybrid cloud can take many forms
