Scavenger Hunt – Week 04 – The PC at Work

Unit 1: Purchasing PCs for Work 04.01-Purchasing PCs for Work  What factors typically drive personal purchases of IT? o If it feels good, do it o Flavor of the day – jump on bandwagon o Lowest purchase price o Hot Rod Syndrome – gotta have the best of the best  By contrast, what factors typically drive corporate purchases of IT? o Business requirements Identify what the requirements are and then establish what we need based on that TCO – total cost of ownership  Don’t want something you’ll have to put a lot money into later How do standardized purchasing agreements reduce IT acquisition costs? o More you buy, higher the discount  Volume -> Discounts o Standardization drives volume  And bring other benefits – all parts the same can fix it easily with low costs Define the term BYOD. o Bring Your Own Device What are the characteristics of a BYOD program? What are the benefits of BYOD? o Provide an allowance to go out and select/maintain your own device  



 

Employee responsible to take care of device Consumerization of IT Benefits...  BYOEverything  Shared Cost  Employee satisfaction What is the “Consumerization of IT”? What factors led to it? How does this impact corporate IT? o Employees started using consumer products for business purposes because they could be more productive with their own device. o Easier to use, cheaper, Newer and more powerful features o Impact:  BYOE  Shared Cost  Employee Satisfaction o o o



04.02-PC TCO  What is TCO? o Total Cost of Ownership  What are Direct Costs and Indirect Costs? o Be able to identify whether a specific cost of operating a PC is Direct or Indirect.  Direct  Hardware, Software, Facilities



 IT Operations  Administration  Indirect  Not directly related  Training, Fixing and downtime,  But can be costly What are the characteristics of the two different PC management styles – Unmanaged vs. Managed? o Unmanaged  User do it themselves the way they want to o Managed  Professional IT staff use software tools and processes and policies to consistently and automatically manage the pcs in the organization What is the single most expensive component of Direct Cost? o Software What single component of Direct Costs can bring the biggest savings if it is locked and well-managed? o IT Support Know rough annual TCO numbers for the following scenarios, as well as the percentage savings:



Scenario TCO – Direct Costs only TCO – Direct and Indirect Costs Well-Managed $1700 $3300 Unmanaged $2000 $6500 Percent Savings 15% 43% for Well-Managed Note: by “rough” I mean to the nearest $100. I’ve provided a couple values to get you started. “The $1000 PC is a Myth.”

Unit 2: Managing PCs at Work 04.03-Managing PCs at Work  What is an “image”? What is a “gold image”? How are images used? How do they impact TCO? o Image = OS + Applications + Settings o Golden image  Built once  Test and tweak  Deploy repeatedly... automatically  Reduce indirect and direct costs in the long run  Methods for application deployment and their implications for TCO o Manual workflow 1. User downloads the app themselves  They mess it up and technician comes out and fixes  Direct costs – because user has to pay for it now  2. They submit a request for the technician to come out and download it  Indirect cost – because they’re losing productivity by waiting around for the technician Automated workflow  User requires an application to do work, they submit a request to use a certain application -> technician approves -> an app automatically gets downloaded -> a lot easier 

o



What is Patch Management? Why is it necessary? Who should do it? o Bugs happen Must patch OS and applications Can’t trust users  Automated system  Labor savings  Reporting User Account Types o What are they and how are they different?  Administrator – full control of the system  Standard User – customize their own account setting, save files, but are prevented from making system-wide changes o What best practice does Mr. Olson recommend?  Give “Standard” accounts to users o How does each impact TCO?  System settings – contrast user settings vs. computer settings o User settings – follow that user no matter which computer that user is using. o Computer settings – affect the way the computer operates no matter who is using the computer. o o

What is Microsoft Group Policy? What is its role in managing systems at work?

 An infrastructure that allows you to implement specific configurations for users and computers  A system that lets us create/manage settings or groups of settings  Policies set to make sure everything is going smoothly and productively What is the purpose of PC instrumentation? How does IT learn about PC problems? o Detect and report PC problems o Central management console  A system that has all the computers attached to it, so technicians can see which computer is having issues and can help it o S.M.A.R.T.  Self Monitored Analysis and Reporting Technology  Can sense that a computer will have problems before the computer completely goes down  Warning for failed CPU fans Leading management systems… o What is Microsoft’s solution?  Microsoft System Center Configuration Manager o What “world-class” system was mentioned for managing Macs?  JAMF Briefly, what are the three motivations for properly managing computers at work? o TCO o Compliance o Security

04.04-Thick or Thin  What are DaaS and VDI? How are they similar? How are they different? o DaaS – Desktops as a Service  In the cloud o VDI – Virtual Desktop Infrastructure



 

 On-prem, on a server o Similarities  Virtual “desktop”  Data storage  Well-managed  Secure Compare and contrast Thick Clients vs. Thin Clients. o What are their characteristics?  Thick –  Traditional PC Model  Everything happens on end user device o Powerful CPU, lot of RAM/storage o Software o Everything happens right in front of them  Thin –  DaaS/VDI o Processing done on the server (since it’s virtual; everything happens away) o Only input/output occurs at end user devices o Mouse and Keyboard use  Many form factors – desktop, notebook, tablet o Simple hardware o Virtualized PC and data in datacenter o Potential for lower TCO o Where does the work happen? Where is the software? Where is the data? o How do acquisition costs compare? Software costs?  Software cost depends  Gonna have to do the math o How does maintenance compare?  Daas/VDI reigns supreme – more reliable

The lecture provides recommendations for choosing thick vs. thin clients in for several business use cases. Understand the reasoning for each so that you can evaluate business scenarios and provide recommendations. How does the “hybrid” scenario work? o You use a mix of both thick client traditional PC + DaaS

04.05-Enterprise Mobility Management  How does the Consumerization of IT impact mobile devices in the corporate environment? o There is a lot of competition in the IT industry because corporate consumerization is so high 

All firms want to use it because it increases productivity



What are the implications of Mobile Device BYOD for Business? (a.k.a. headaches) o Securing corporate email/data Ensuring regulatory compliance  Making sure no laws are being broken on the IT end because of all the sensitive intel o Cost of supporting BYOD  Multiple platforms  Idiosyncrasies among models  Moving target What can a “lightweight approach” to EMM do for you? What does it require? o Simple, Takes advantage of features that are built into most mobile phones together with server capabilities to manage access to services o Requires... o





 Pins enhanced security  Can require encryption  Remote wipe What is EMM? – Enterprise Mobility Management o What are its key capabilities?  Security  Password enforcement  Inactivity lock  Device wipe  Audit trail/logging  Jailbreak detection  Software distribution  App downloader  App verification  App update support  App patch support  Policy/compliance management  Deny noncompliant devices  External storage blocking  Restrict new apps  Control web access  Cost containment  Inventory management  Basics o Hardware info o Who owns it? o Software info  Advanced o Monitor performance, battery life, memory utilization o Configuration change history o Lost phone recovery o What are "Containers"? What's the benefit to the company? To the user?  Containers  Separate personal from business

   

o Apps o Data o Email Selective wipe Encrypt work container Barrier between containers

What is “remote wipe”? How is it different for lightweight approach vs. full EMM suite? o Remote blows away just the user’s personal stuff and not the company’s stuff

04.06-PCs and Power  Potential savings in electricity costs for PC’s in a well-managed scenario: 35%  What power reliability problems affect our IT devices? o Surges o Brownouts – not enough power to meet the requirements o Blackouts  What solutions address those power reliability problems? o Surge protector o UPS – Uninterruptable Power Supply o Generator
