Standard models include flat networks or VLANs for separation of servers and traffic • Manages IP addresses, allowing for dedicated static IPs or DHCP or floating IPs • Floating IPs allow traffic to be dynamically rerouted to any of your compute resources, allowing you to redirect traffic during maintenance or in the case of failure • Users can create their own networks, control traffic, and connect servers and devices to one or more networks This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. OpenStack Networking - Neutron
    33. 33. • Get started with simple Ubuntu 12.04 LTS: – I will show a demo of: • Where they should go • What they do • How you can set up the basic cloud This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. How can I start building ?
    34. 34. • Cost – Many systems have variable demands  Batch processing (e. g., The New York Times)  Web sites with peaks (e. g., Forbes)  Startups with unknown demand (e. g., the Cash for Clunkers program) – Reduce risk  Don't need to buy hardware until you need it This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Goal 1 – Cost Control
    35. 35. • More than scalability - elasticity – Ely Lilly in rapidly changing health care business: • Used to take 3 - 4 months to give a department a server cluster, then they would hoard it – Using EC2, about 5 minutes: • And they give it back when they are done • Scaling down is as important as scaling up This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Goal 2 - Business Agility
    36. 36. • System Administrators often talk about servers as a whole unit that includes hardware, OS, storage, and applications • Servers are often referred to by their function, e. g., Exchange server, SQL server, and File server • If the File server fills up or the Exchange server becomes overtaxed, then SysAdmins must add in a new server This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. The Traditional Server Concept
    37. 37. • Unless there are multiple servers, if a service experiences a hardware failure, then the service is down • SysAdmins can implement clusters of servers to make them more fault tolerant. However, even clusters have limits on their scalability, and not all applications work in a clustered environment This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. The Traditional Server Concept
    38. 38. • The “no-need-to-know” in terms of the underlying details of infrastructure, applications interface with the infrastructure via the APIs • The “flexibility and elasticity” allow these systems to scale up and down at will: – Utilizing resources of all kinds: • CPU, storage, server capacity, load balancing, and databases • The “pay as much as used and needed” type of utility computing and the “always on, anywhere and any place” type of network-based computing 38 This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Basic Cloud Characteristics
    39. 39. • Cloud are transparent to users and applications, they can be built in multiple ways: – Branded products, proprietary, open source, hardware or software, or just COTS PCs. • In general, they are built on clusters of PC servers and COTS components plus Open Source software combined with in-house applications and/or system software. 39 This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Basic Cloud Characteristics

This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Pay-Use Example: stock.com
    41. 41. • Host the website in Amazon's EC2 • Provision new servers every day, and deprovision them every night • Pay just $0.10 per server per hour, more for higher-capacity servers • Let Amazon worry about the hardware! This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Times Solution
    42. 42. • Most companies don't WANT to do system administration: – Times Of India says: • We are is a publishing company, not a software company • But beware: – Do you really save much on sys admin? – You don't have the hardware, but you still need to manage the OS! This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. Goal 3 - Stick to Our Business
    43. 43. • Virtual servers can still be referred to by their function, e. g., email server and database server • If the environment is built correctly, virtual servers will not be affected by the loss of a host • Hosts may be removed and introduced almost at will to accommodate maintenance This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. The Virtual Server Concept
    44. 44. • SaaS is where an application is hosted as a service provided to customers across the Internet. – SaaS alleviates the burden of software maintenance/support, but users relinquish control over software versions and requirements. • PaaS provides a computing platform and a solution stack as a service. – Consumer creates the software using tools and/or libraries from the provider; also controls software deployment and configuration settings. – Cloud service provider provides the networks, servers, storage, and other services. 44 This document is confidential and not for unsolicited distribution. Copyright © 2013, Imaginea Technologies Inc. All trade names and marks belong to their respective owners. All rights reserved. SaaS and PaaS
    45. 45. • IaaS providers offer virtual machines, virtual-machine image libraries, raw (block) and file-based storage, firewalls, load balancers, IP addresses, VLANs, and software bundles. • Pools of hypervisors can scale services up and down according to customers' varying requirements. • All infrastructure is provided on-demand.
