1 Head in the Clouds? a birds eye view of technology implementation options

2 Whazzat? New technologies! VDI Cloud Azure Virtualization Hyper-V SAN NAS VmWare Xenserver Parallels Thin client Citrix Wise

3 What is the Cloud? Cloud is the idea of working across the network, where applications and files are hosted remotely


5 More than one path to get there

6 Why do you care about the cloud? $$$$ how does it affect you financially? Cloud computing can affect your compliance. Cloud computing can affect your liability Worker mobility Platform agility Productivity

7 Types of Cloud computing Hosted services – 3 rd party hosts your data and applications – Microsoft hosted exchange – Gmail – Rackspace web server hosting – Terremark data center – Rent it Fog (local cloud) – Centralized storage – Hardware liberation – Telecommuting – Rapid replacement – Virtualization – Own it

8 Hosted services Pros – No backup worries – Reduces IT staff burden – SLA (service level agreement) – Your IT staff cant screw it up – Mobility – No upgrade problems – Scalability Cons – Recurring Costs – Data privacy not guaranteed – Interoperablity issues – Your issues will get resolved at their convenience – Bandwidth is key! – No internet, no service!



11 Rule of Thumb Hosted services requires adequate bandwidth to the host, so calculate in the cost of internet bandwidth requirements. Consider the no internet access scenario.

12 Examples of hosted Solutions External Data center Carbonite Gmail for business Hosted Exchange Azure Amazon S3 Rackspace Panda managed office protection ISP hosted DNS Mail washer OpenDns Postini Microsoft Office 365 Warranty support

13 99.999% High availability…can be costly to do it yourself Backup generators, battery backups, load balanced server farms, shared storage, redundant storage, offsite backups… How much downtime can you tolerate?

14 Cloud failures: Amazon s3 Gmail Microsoft T-mobile sidekick (sun) Microsoft BPOS

15 Matt Rosoff | Apr. 22, 2011, 12:21 PM Amazon Web Services crashed yesterday, taking thousands of Web sites -- mostly smaller startups -- with it. The outage is now in its second day, and while the company says service has been partially restored and some sites like Reddit are back up, others like Quora and Box Office Mojo are still offline. ond-day-lots-of-sites-still-down-2011-4

16 Gmail outage passes 24 hours for some (updated) By Seth Weintraub February 28, 2011: 1:01 PM ET A small percentage of people have been without their Gmail accounts since Sunday. Imagine if you lost your entire email inbox, sent box, folders –everything. A small number of Gmail users logged into their accounts over the weekend to find just that.... Initially, the outage was said to have affected.29% of global Gmail users.... That was at 3:00 ET. Sunday. Since then Google has issued numerous updates including a revised downward estimate of.08% of all Gmail users affected – which comes out to about 150,000 users world wide. In the grand scheme of things, that is very few, unless you are with out email today.

18 Discussion of Fog Pros – Still in house – Hardware independent – No internet bandwidth required – You can own it – High Availability – Reduced power consumption – Efficiencies of scale Con – Requires storage system – Requires virtualization – Complexity – As good as your IT staff

19 Case study antivirus Hosted cloud version ~13.00 /year per seat 300 users $3900/ year Management console is accessable from anywhere Clients report back to console more slowly No on premise server required In house version (not cloud) ~8.00/year per seat 300 users 2400/year Requires an old surplus server and minor attention from IT staff. Savings $1300 or $5/user

20 Case study Email 20 users Hosted exchange $10 per month per user 20 users $200 per month Break even at 58 months $16800 over 7 years Minimal IT skill required Exchange 2003 Server 5000 Exchange license 700 Operating system 500 Cals 45/user 20*45= 900 Backup software 700 Tapes and tape drive 1000 Spam filtering 3000 $11,800 Ran for 7 years before upgrade No Vendor tech support included

21 Case study Email 200 users Hosted email service $168,000 over 7 years Exchange 2003 $19,900 over 7 years

22 Case Study Email 500 users Hosted email $420,000 Exchange 2003 $33,400

23 Summary email hosting

24 Case study Microsoft office 365 Office 365 E3 plan Hosted exchange included $24/user per month Version updates automatically $672 over 4 years/user Office 2010 $280…doesn’t include hosted exchange service Can probably run it for 10 years $280 over 4 years/user REMEMBER OPEN OFFICE is FREE!!!

25 Office 365 4 year refresh

26 OPEN SOURCE ALTERNATIVES Open source software is: – FREE of licensing costs – Not quite as good but pretty close – May have a steeper learning curve – Less prone to viruses/ exploits – Possibly less user friendly – Makes transitioning to free operating systems easy

27 Rule of Thumb Using open source software where you can may be an excellent cost saving measure. If it doesn’t work out, you didn’t spend anything on it…(just time and effort).

28 Are you an Excel Ninja? If you have a spreadsheet that does more calculations than Einstein….You probably wont like Open Office.

29 Open Source Free software Linux – Your home router runs Linux – Apache server (like IIS) Open office (Oracle/Sun)/ Libre Office FireFox browser Android (sort of)

30 Office scenario Using the same office software for a 5 year life span Open Office = free, less user friendly, harder to support, reduced functionality Office 2010 = $280 Office 365 = $840

31 GET REAL! Or go Virtual? What? Virtualization is replacing a machine with a program Why? When physical machines die, recovery takes a while Virtualization frees you from one application per server Recovery becomes much quicker Virtual machines can grow as needs grow


33 Virtualization costs? Hyper-V (microsoft) $28 (or included with your Operating system free) Citrix Xenserver (free versions, or paid versions with automatic failover, and support) Vmware (free versions or paid versions with automatic failover, and support 0-$7000)

34 Vmware VS Xenserver Vmware is more fully featured 009/04/price-comparison- citrix-xenserver-enterprise- with-essentials-vmware- infrastructure- enterprise.html Vmware is more expensive



37 Vm flexibility and scalability Physical machines Each has own disk space, ram and processors. Cannot share Cannot scale up Good resources get trapped in an underutilized machine Virtual Machines Can move from host to host Can be allocated more or less resources as needed Reduce Air conditioning and electrical costs Cloning Snapshoting

38 Hidden cost of virtualization? Comlexity Plan on additional training Plan to have in house knowledge You will need a SAN to leverage the full Benefits of virtualization Initial Costs high for infrastucture to support it, but saves money over time.

39 Rule of Thumb If you are looking for a free virtualiztion platform, Xenserver has the most features All virtualization platforms are Linux based (yes even Microsoft’s Hyper-V) so having Linux skilled staff is a good idea

40 Virtualized workstations? Pros Makes endpoint maintenance free Endpoints for $300 Data is secure in storage Image based, mass produced, stays fresh Cross platform Can reuse/extend obsolete workstations Cons Up front cost Deployment complexity Storms of user activity must be planned for not the best choice for travelers, branch offices, patrol cars, or locations with poor internet service


42 Storage SAN SAN- Storage area network iSCSI is much less expensive than Fiber Channel, but not as fast Think of it a huge hard drive on it’s own network, that many can share Large scale solution NAS Network attached Storage Think of it a huge hard drive across the network, that many can share Storage traffic is in competition with regular traffic A smal l scale solution

43 Rule of Thumb Shared storage can save you money if you have Large amounts of data (especially redundant data) Average desktop cost for storage per user is $120. You can use that number to calculate 200 users = ~$24000 in storage

44 San on the cheap We were able to implement a GB san over existing fiber for about $4000 in network gear Our two 8 TB Storage arrays were about $16000- This provides 8TB of storage that hosts all the storage needs of the virtualization farm, backups, and file server for 300 users. BUT, they still have local hard drives ($120 each)

45 Advanced SAN features These features can reduce total storage size, at a performance cost: Data Depulication – Can reduce the total size of the storage by half or more (great for storing backups and virtual machines) Thin Provisioning – Can allow virtual servers to share disk space reducing the total storage size

46 Compliance Virtualization, centralized storage make it easy to enforce records management retention policies and ensure the data availability.

47 What type of organization are YOU Do it yourselfers? Highly trained staff with customized software Microsoft penny pinchers? Small IT staff, still trying to milk some life out of your old but still useful stuff. Microsoft Early Adopter? Do you have your own sharepoint site using InfoPath forms?

48 Do-it-yourself-ers If your IT department has people in IT who’s job funcion you can’t fathom…this might be you. You may do best with open source altenative Keeping things in house Invest in your staff and make sure they cross train and document what they create.

49 Rule of Thumb If you have a highly customized environment, especially if it’s based on open source software, invest in your staff.

50 Microsoft Penny Pinchers If the start button on your computer is gray this might be you! You might appreciate software ownership. Be sure to invest in good 3 rd party patching and security systems. Expect migration headaches.

51 Rule of Thumb If you are hanging on to old software, it’s a good idea not to skimp on patching and security software. Introduce open source solutions where you can, to decrease migration headaches.

52 Microsoft Early Adopter If you are an early adopter of microsoft technologies, Software Assurance and Office 365 might be good choices. You will have cutting edge capabilities Web apps are not the same as the desktop apps, and require connectivity. Greater costs, fewer headaches?
