Why Open Source and the Cloud Computing?

•  User-‐Driven Context from Solving Real Problems •  Lower Barrier to Par3cipa3on •  Larger user base, users helping users •  Aggressive release cycles stay current with the state-‐of-‐the-‐art

•  Open Source innova3ng faster than commercial •  Open data, Open standards, Open APIs

Quick Cloud Computing Overview or the Obligatory “What is the Cloud Explanation”

Five Characteristics of Cloud

1.  On-‐Demand Self-‐Service

2.  Broad Network Access 3.  Resource Pooling 4.  Rapid Elas3city 5. Measured Service


5

Cloud Computing Service Models

USER CLOUD a.k.a. SOFTWARE AS A SERVICE Single application, multi-tenancy, network-based, one-to-many delivery of applications, all users have same access to features. Examples: Salesforce.com, Google Docs, Red Hat Network/RHEL DEVELOPMENT CLOUD a.k.a. PLATFORM-AS-A-SERVICE Application developer model, Application deployed to an elastic service that autoscales, low administrative overhead. No concept of virtual machines or operating system. Code it and deploy it. Examples: VMware CloudFoundry, Google AppEngine, Windows Azure, Rackspace Sites, Red Hat OpenShift, Active State Stackato, Appfog SYSTEMS CLOUD a.k.a INFRASTRUCTURE-AS-A-SERVICE Servers and storage are made available in a scalable way over a network. Examples: EC2,Rackspace CloudFiles, OpenStack, CloudStack, Eucalyptus, OpenNebula

The Three Virtual Pillars of Cloud Computing

Compu

Network

Storage

Hypervisors

Open Source •  Xen, Project Xen Cloud PlaMorm (XCP) •  KVM – Kernel-‐based VirtualizaGon •  VirtualBox* -‐ Oracle supported Virtualiza3on Solu3ons •  OpenVZ* -‐ Container-‐based, Similar to Solaris Containers or BSD Zones •  LXC – User Space chrooted installs Proprietary •  VMware •  Citrix Xenserver (based •  Microsoc Hyper-‐V •  OracleVM (Based on OS Xen)


14

Scale-Up or Scale-Out

VerGcal Scaling (Scale-‐Up) Allocate addi3onal resources to VMs, requires a reboot, no need for distributed app logic, single-‐point of OS failure

Horizontal Scaling (Scale-‐Out) Applica3on needs logic to work in distributed fashion (e.g. HA-‐Proxy and Apache, Hadoop)


15

Sourcing Cloud Appliances Tool/Project What you can do with them

Bitnami BitNami provides free, ready to run environments for your favorite open source web applica3ons and frameworks, including Drupal, Joomla!, Wordpress, PHP, Rails, Django and many more.

Boxgrinder BoxGrinder is a set of projects that help you grind out appliances for mul3ple virtualiza3on and Cloud providers

Oz Command-‐line tool that has the ability to create images for common Linux distribu3ons to run on KVM

SUSE Studio SUSE Studio supports building and deploying directly to cloud services such as Amazon EC2.


16

Cloud Computing Storage Project DescripGon

Ceph Distributed file storage system developed by DreamHost

GlusterFS Scale Out NAS system aggrega3ng storage over Ethernet or Infiniband

OpenStack Storage

Long-‐term object storage system

Riak CS Riak CS is open source socware designed to provide simple, available, distributed cloud storage at any scale. Riak CS is S3-‐API compa3ble and supports per-‐tenant repor3ng for billing and metering use cases.

Sheepdog Distributed storage for KVM hypervisors


17

Software Defined Networking (SDN)

Cloud Promise, Reality and Networks

Cloud Promise Cloud Reality Centralized ConfiguraGon and AutomaGon

Without true virtualiza3on, network devices must s3ll be manually configured.

Instant Self-‐Service Provisioning

In a physical network, it could take a long 3me for network engineer to provision new services.

ElasGcity and Scalability By horizontally scaling up the physical network, elas3city is lost.

Designed for Failure Failover can be automated and physical network limita3ons can be alleviated.

Open Flow

OpenFlow enables networks to evolve, by giving a remote controller the power to modify the behavior of network devices, through a well-‐defined "forwarding instruc3on set". The growing OpenFlow ecosystem now includes routers, switches, virtual switches, and access points from a range of vendors.

Software Defined Networking (SDN) Project Description

Floodlight The Floodlight controller is an enterprise-‐class, Apache-‐licensed, Java-‐based OpenFlow Controller.

Indigo Indigo is an open source project to support OpenFlow on a range of physical switches. By leveraging hardware features of Ethernet switch ASICs, Indigo supports high rates for high port counts, up to 48 10-‐gigabit ports. Mul3ple gigabit pla^orms with 10-‐gigabit uplinks are also supported.

Open Daylight Linux Founda3on Collabora3ve Project based on Cisco One Controller and plugins from numerous vendors in development. E.g IBM DOVE

OpenStack “Quantum” Networking

Pluggable, scalable, API-‐driven network and IP management

Open vSwitch Open vSwitch is a open source (ASL 2.0), mul3layer virtual switch designed to enable massive network automa3on through programma3c extension, while s3ll suppor3ng standard management interfaces and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag).
