3 Virtualization What Is It? General, Scope, Trends

4 Virtualization What Is It? The creation of a virtual rather than an actual version of something Virtual Private Network Virtual Network Virtual Reality Virtual Desktop Virtual Server Server Virtualization Running applications in separate, isolated partitions (separate "virtual machines") within a single server (pcmag.com) 2011 Avaya Inc.

5 At the Base Level: Recovering Lost Resources Before Spare Cycles App 1 They used to call it time sharing but now it encompasses a lot more After Spare Cycles App 1 App 2 App 3 App 4 App Avaya Inc. All rights reserved. 5

6 History Repeats Itself! Or, Good Ideas Never Die August 2 nd, 1972: IBM announced VM Virtual machine, storage, etc. Not just time sharing Sometime in the 90s: What s a mainframe? We got PCs! Sometime in the 00s: Ya know, that VM thing was a pretty good idea 2011 Avaya Inc. All rights reserved. 6

9 Server Virtualization Network Virtualization Today s Physical Network Virtualization Server Virtualization Allows aggregation of multiple independent virtual servers to exist on a physical server Network Virtualization Decouples the physical infrastructure t from the connectivity services making the network adaptive and dynamic with simple one-touch provisioning but that s another topic for another day 2011 Avaya Inc.

10 IEEE Shortest Path Bridging (SPB) New Standard for Multi-Service LAN Design Supports the Virtual Server / Virtual Service Envornment Enclave A Enclave B Virtual Machines Virtual Machines but that s another topic for another day 2011 Avaya Inc. All rights reserved. 10

11 Virtualization Impact Benefits

12 Real Virtual Trends Virtual Machines and Market Share Through 2012 Source: Gartner % 45% 40% 35% Virtualized Workloads 30% 25% 20% 15% 10% 5% 0% (World s Most Unattractive Chart) 2009 Forecast: 50% of workloads virtualized by late Reality: Yup, it came true Infotech: 58% by 2012, 70% in 2013 Affects markets beyond current server virtualization vendors Storage Backup and Recovery Application and service level management Capacity planning Desktop Virtualization Networking 42% OF COMPANIES ARE VIRTUALIZING OR PLANNING TO VIRTUALIZE THEIR UC APPLICATIONS (Nemertes 2012) 2011 Avaya Inc.

13 Virtualization Environments VMWare not the only game in town, but close to it Microsoft a distant second Citrix & Linux (Xen Hypervisor) primarily deployed in specialized roles Infotech Avaya Inc. All rights reserved. 13

14 Deployment in a Virtual Machine Better use of server & storage resources Green impact: lower energy, carbon impact Time-of-Day load management Reduced real-estate estate footprint or outsource to cloud Transform compute power to a generic commodity Decoupling of hardware & software Reduce BIOS & other interoperability issues Replicate model in storage arena Effectively outsource HW qualification to VM vendor Result: Faster, easier, more cost-effective deployment 2011 Avaya Inc. All rights reserved. 14

15 Capacity Flexibility Growth in requirements can be met on the fly Additional resources can be added often dynamically Migration to newer servers can be done in background Services can be moved seamlessly Far less impact than the service on server model 2011 Avaya Inc. All rights reserved. 15

16 Reliability of a Virtual Machine Decouple services from physical locations Ability to move services Proactive load balancing Easier maintenance windows Proactive disaster avoidance coming storm? Backup, restore, snapshot services Enhanced failure recovery Expand beyond app supplier s redundancy Run otherwise non-redundant services redundantly 2011 Avaya Inc. All rights reserved. 16

17 Methods of Virtualization Vendor-app provided virtualized appliance (ME) Premise-deployed virtualization Most common when virtualization is spoken of Cloud-based d service Turnkey Pod solution Hybrid Depends on what you have installed and what is offered 2011 Avaya Inc. All rights reserved. 17

20 Typical Virtualization Services (VMWare Terms) Vmotion & Storage VMotion Ability to move a service on-the-fly Applies to both compute & storage Scheduled, triggered VMWare High Availability Ability to shadow an entire process Doubles computer requirements but allows a non-redundant app to become redundant d Snapshot Ability to capture an image for restoration, troubleshooting Fallback for patching Virtual network switching Within & across physical servers Plays well with SPB virtual networks 2011 Avaya Inc.

21 Virtualization Considerations Concerns & Questions to Ask

22 Concerns Vendor Support? Is the application supported by the vendor? Can t assume everything runs in virtualized environment Might work fine until you call for support What environment(s) are supported? What are the required resource levels? 2011 Avaya Inc. All rights reserved. 22

23 Concerns And What Makes UC Different? Organizational challenges Do Telecom & IT get along? Who will own the service? Technology biases between organizations? Capacity constraints in virtual compute environment? Who pays for expansion? Separate deployment? CapEx & OpEx models variable & possibly complex For UC, often unable to virtualize everything Unsupported apps Certain real-time media processing Hardware-specific functions lines, trunks, gateways (May be able to transform service, e.g. T1 SIP Trunks) Security & DMZ considerations 2011 Avaya Inc. All rights reserved. 23

24 Planning Cost structure of the product Does it favor virtualization? Hardware, software, server, per-user costs Compute, memory, storage requirements of solution Can non-virtual needs be transformed e.g. TDM trunk -> SIP trunk Infrastructure required for non-virtualized portions? Who has the expertise in virtualization? Who will install? Maintain? Training, certification, etc Avaya Inc. All rights reserved. 24

29 Why Virtualize? Reducing hardware footprint Running multiple operating systems on one physical machine Adding abstraction layer between OS and hardware Running multiple l operating systems on one physical machine Better resource utilization No more idle servers VMs are independent and unaware of each other IDEXX Laboratories, Inc. All rights reserved.

30 Why Virtualize? Treat the whole server as a single entity Entire state can be saved to a file for backup Running state can be moved between hardware hosts Hardware Independence Replace servers with no downtime Have migrated whole disk frames with no downtime Applications don t need to worry about the hardware IDEXX Laboratories, Inc.

33 How did we virtualize? In house expertise is important to us We stated that VMware is our corporate enterprise solution / direction IDEXX is 90+% virtualized!!! IDEXX Laboratories, Inc. All rights reserved.

34 Applications Why can t they be virtual? All new applications targeted for virtualization All Communications and Collaboration Tools are virtual Unified Messaging with Speech to Text Instant Messaging SharePoint Linux and Oracle Middleware applications are highly virtual Almost all Windows Servers and applications are virtual SAP in process of moving apps to virtual environment IDEXX Laboratories, Inc.

35 Future plans with Telecom Continue roles and responsibilities established with UM deployment Researching Avaya Aura for virtualization ti IDEXX Telecom wants to move to a virtualized application suite and pushes its vendors for such capabilities Most Vendors understand our requests and have road maps to meet those now or in the next year IDEXX Laboratories, Inc.
