Cloud computing

•Definition (NIST):–Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources

•Types–Private/public/hybrid

•Service models–IaaS–PaaS–SaaS

Example of cloud.

What is OpenStack?“OpenStack is a cloud operating system that controls large pools of compute, storage, and networking resources”.

– OpenStack website.

Who is using OpenStack?• Paypal, eBay, AT&T, Telefonica, Dell, HP, IBM, RedHat, Canonical,

Rackspace, VMWare, …

Compute (Nova)• Manage machines at scale• Supports (ordered by maturity)

– QEMU/KVM– Hyper-V– VMWare– Xen– Bare metal– Docker containers– LXC

• Alternatives out there: Amazon EC2, Docker

Identity Management (Keystone)• Defines projects, users, groups, roles and their permissions• Authentication

– Name and password– LDAP– Other external methods (ie: Kerberos)

• Authorization• Token generation• Domains (higher level tan projects), Federation

Dashboard (Horizon)• Self-service web portal• Provides catalogue of services

Storage• Block storage (Cinder)

– Persisten block-level storage device, aka virtual hard drive• Shared file system (Manila)

– Shared block storage– NFS, HDFS

• Object storage (Swift)– Store and retrieve through HTTP via RESTful API

• Image service (Glance)– Manage VM disk images

Networking (Neutron)• User defined networks• DHCP• NAT• SDN

More services• Ceilometer – Telemetry

– Statistics and monitors for billing, benchmarking, …• Heat – Orchestration

– Composite cloud applications– Kind of like docker-compose

• Sahara – Elastic Map Reduce– Hadoop cluster provisioning

• Magnum – Containers– Expose Docker and Kubernetes

Example applications

• High throughput computing• Web hosting• Public cloud• Web service• eCommerce• Big Data• DBaaS• Video Processing and Content Delivery

• From the sample configurations in the OpenStack website:– http://www.openstack.org/software/sample-configs
