Wangoh Dynamics Systems Network and Telecommunication Companies and Alternatives Memo To: The Government of Sierra Leone (West Africa) From: Saa E. Fillie-Founder/CEO and Network Engineer Date: March 20. 2013 Ref: The Cost Good thing about Virtualization Technology Many lively companies are researching to better IT departments, improve business designs and produce lower functioning costs.

Till a few years in the past, it looked like as if an all-encompassing answer to those problems continues to be taken care of by virtualization that is certainly now a trusted, efficient and customizable way to those business requests and more.

Whether utilized to provide better customer service, being more earth-friendly or to gain more firm memory, the virtualization technology of today provide many benefits to enterprising corporations all over the world, creating innovative approaches to work primarily based problems on a daily basis. Virtualization hasn’t only captured the business world by simply storm having its innovative and creative solutions but it also gives proven positive aspects in several parts of industry, IT and service. Below is a list of a number of the advantages and solutions that virtualization technology can offer the enterprise around the globe.

Virtual Desktops Many corporations and enterprises are looking to lessen their impact and produce more efficient operating systems. This can be finished with one aspect of virtualization, digital desktops. Online desktops are able to create more space within a computer or on actual workplace space by using software which usually expands a desktops environment beyond physical limits through virtualization. This could create a even more eco-friendly environment with much less computers using energy and lower functioning costs and also gives continuous changes between multiple operating system.

Increased System Security A anxiety about many enterprises considering virtualization in their organization is that all the advantages of this kind of technology will compromise the safety of sensitive, private and legal company information. However , that is not the case, in fact virtualization in business delivers enhanced security, making it more challenging for cyber criminals to find key information. Unlike other burglar alarms, virtualization is able to single out and trace needs.

If a ask for seems rubbish or faulty, virtualization protection technologies is going to reroute hackers to another location, acquiring and keeping enterprising business information protected from harm. Better System Dependability Non-virtualized systems and devices are more vulnerable to crashes and memory corruption due to software installments just like device individuals. Through virtualization, I/O assets can be separated providing better security (see above, ) reliability and even availability across devices for people who do buiness purposes. Disaster Recovery

Over the same lines as better system reliability, virtualization as well provides ambitious businesses with better, quicker and more protect disaster restoration. This is feasible because this technology is able to take a virtual graphic or information and transfer it to a new server inside the instance which the original storage space may be ramming. This helps prevent information damage and provides a consistent stream of secure very safe information. Space and Server Consolidation For the organization has a physical data source, it can take up to ten devices to provide a simlar amount of workload to one virtual machine.

Therefore up to 10 applications can be ran over a solitary electronic machine, consolidating physical space as well as server use, for that reason saving strength usage, functioning costs and server expenditures. Scalability 1 advantage of virtualization technology is its unique ability to be scalable. What this means is that as opposed to purchasing Times amount of computer recollection or MEMORY for a business, the possibilities with virtualization will be endless. The workload and space required one month may change in another and virtualization accommodates all those changes by fluxuating to fit the requires of an organization at the time of make use of.

This as well saves on energy consumption and operating costs because virtualization service providers oft will only impose for what utilized. Endless Memory space and Accessibilities One aspect of scalability is usually virtualization’s advantage of seemingly endless memory. Keen businesses will take advantage of inexhaustible memory to house business data, client details, invoices and financial documents all in an accessible, crash protected and secure place. Virtualization is accessible anywhere there is certainly an internet connection, allow for usage of important business information all over the world.

This is just the thing for traveling companies, work from home personnel or gain access to away from work. This also allows businesses to offer better customer service to clients as a result of ease of get as well as the quick pull up of saved details stored in a limitless memory location. Many enterprising companies are researching ways to better THAT departments, increase business versions and create lower functioning costs, all of these can be achieved with the modern day marvel technology that is virtualization.

Whether used to provide better customer service, being more earth-friendly or to gain more company memory, the virtualization technology of today offer many benefits to enterprising corporations all over the world, creating innovative solutions to work structured problems every day. Return on Investment College of thoughts have asserted in various program about the huge capital purchase return in virtualization, you will discover multiple factors which determine how to go about deciding what kind of monitoring an info Technology (IT) department should certainly embark on.

To be able to properly assess a specific THAT environment, one particular must first determine regardless of whether to virtualize. Virtualization may be stressed as a life saver for countless THIS departments in the last few years. What first needs to be determined however , is if in reality an organization seriously needs to virtualize. Perhaps data source, application computers, network services, etc avoid truly ought to become virtualized, maybe they certainly. What we are trying to determine today is the Revenue (ROI) pertaining to virtualization.

Technologist, Researchers and Students helps quantify virtualizing an IT infrastructure. If an organization is in the process of attaining a new firm (or becoming liquidated) and subsequently going locations, they must first take a look in their hardware room*. When it is overcrowded, below powered or perhaps outdated, in that case yes¦ virtualization is probably crucial. What everyone in the THIS department would like to know then, is virtualization right for my personal organization and more importantly my personal department? [pic]

The resources getting saved in just electrical power and equipment along are staggering. Keeping costs reduced for the complete organization is obviously crucial, in particular when it comes to things such as never needing to redeploy software solutions*. This will save you as well as subsequently funds: no storage space hardware relaxing costs, limited annual server-related power costs*. The greater queries then happen, how much time will it have a department to make the complete change? Will the ROI be really worth the increased labor hours to become fluent with the virtualized world?

What sorts of challenges can come about from your overall business perspective? |Reducing Infrastructure Costs Through Virtualization | | || | |Introduction | | |Nowadays, we all live in doubtful times all around the world.

When it comes to buildings | | |and style, we must believe a lot more in costs”unlike in other times, once we used to think| | |first of the remedy and then in costs. Whenever we had a streamlined and defined return upon | | |investment (ROI), only then simply did the project find the green light. Today, if we think about | |projects, it is necessary to have got a precise finances and defined cost first before we can | | |start to think about the project. | | |Upon brief expression of what IT architecture is definitely, one finds that the version that the complete | | |world favors (because of costs plus the evolution of technologies) is a virtualization | | |model.

Ten years in the past, it was everything regarding decentralization”both in data centers and web servers, | | |and in communication and desktops. Whenever we thought of an application, we often tried to | | |have the tiers of this kind of application because close to the customer as possible, info centers, | | |databases, and e-mail servers had been distributed all over. | |This situation was the result of within face the huge cost of having hardware | | |equipment of multiple large features (such because an eight-processor server and lots and | | |lots of RAM gigabytes) or perhaps having redundant point-to-point communication links with good | | |bandwidth”the cost of which only large companies could consider including inside their | | |architecture.

All this encouraged a decentralized IT administration unit that required| | |specialists in the different platforms of every site. | | | | || | |The First Model | | |Although this model worked well for years, several things were not deemed that today have | | |rendered this model much less efficient because was initially thought. | |[pic] | | | | | |Figure 1 .

Normal scheme | | || | |Taking as an example the analysis of a distributed app that was devised ten years | | |ago, there is an structure in which it was important to have the data near to the client, | | |which led to the following scheme: | | |A database inside the central business office in which the information from the several sites, the | | |database coming from each web page, the application machine from every single site, as well as the local applications| | |that were installed on each computer’s desktop were most consolidated. | | |A replication system among the sources was used pertaining to the circulation of information. | |This drove us to have database operations for each internet site, besides having on each web page | | |an infrastructure administrator who thorough knowledge. | | |Initially, this kind of had (as variables inside the equation) excessive communication-link costs, | | |large servers that symbolized a very high cost, and surgical systems that have been neither | | |very solid nor rigid for changes and in addition had little functionality”that is definitely, | | |they provided very few capabilities or roles within the operative system. | |For lots of the needs in the company, it was necessary to put software that may comply | | |with that features. In addition , in order to carry out the littlest of adjustments, it was| | |necessary to set the server offline and have THIS personnel who represented the average cost. | | |The variable that was not genuinely considered was the updating and maintenance of the entire | | |structure, which at the time”due to the fact that technology did not evolve in the way | | |that it does today”was not this important aspect. | |If we all consider fundamental accounting rules (which I use learned during recent years), one| | |should usually see the THIS personnel as an asset towards the company, with amortization time| | |(which is the period that it will take to shape the person, according to the culture and needs | | |of the company) and an updating cost (which is what has to be invested to experience a person | | |trained in the several technologies as they evolve). | | |Over time, all of this changed, the variables in this equation likewise changed, as well as the | | |updating and maintenance adjustable (which in many cases had not been used into account) | | |started to gain more and more importance. | |This is the equation that we encounter nowadays: | | |Average to low communication-link costs (taking into account the electronic private network), | | |large computers with many RAM gigabytes in average to low cost, surgical systems that had | | |hundreds of inserted and flexible options and lots of functionality (many things already | | |come solved and embedded in the operative program, so that in general it is not required | | |to arranged the server offline to make these changes), average to high workers costs, and | | |average to high updating and repair costs. | |Within the scheme that is encouraged today, many things must be considered, it truly is | | |necessary, consequently , to have the whole scheme in mind”not only a part of it”to avoid | | |making the same faults that we sustained in the past. | | |Nowadays, when doubt (crises, corporate and business mergers, acquisitions, and frequent changes)| | |is all over, it is vital to work toward an environment that could basically support | | |constant dynamic changes. Nowadays, it is necessary to consider platform and | | |application upgrading, growth, and company and budget contractions.

This kind of, of course , will| | |highly influence the model that is to be picked, and that style (taking into mind the | | |aforementioned equation) should be based primarily on the modernizing and maintenance variable. | | |When we consider all of the earlier, we will see that the model that best fits is definitely the | | |virtualization model applied to each of the possible amounts, where all of the equation | | |variables are considered in order to determine feasibility and total cost of ownership | | |(TCO). | |There will be infinite virtualization scenarios”from selecting cloud calculating in certain | | |services and virtualizing (or outsourcing) the full or part of the IT office to using| | |virtualization for machines, applications, or perhaps desktops. | | || | |Server Virtualization | | |Today, there are plenty of important players and technology that have been extensively tested, | | |such as Ms Hyper-V and VMWare.

The hardware costs have gone significantly down: In the event that | | |we would have been to compare four- to eight-processor equipment from the past to just one today, it might | | |result within an important price margin that could be an improvement, and it would be necessary| | |to add the progress which was made in systems and redundancy within equipment, | | |board, hot-plug memories, and so forth. | | |Generally speaking, almost all the components of the machine can be improved without having | | |to take the server offline.

The same thing applies to practical, effectual systems. Because of this | | |we may do away with the idea that utilized in the past, relating to which we all used to | | |divide into distinct hardware parts the different organization applications. Furthermore to | | |this, the advantages of tolerance to failure in the virtualization plans that are used | | |today make it possible to adopt a physical storage space offline with out affecting the virtual | | |server that is using that physical server.

This kind of, of course , means that from a straightforward | | |technical point of view, there is previously a huge benefits in the use of server | | |virtualization. | | |From a great architectural perspective, this allows all of us to respond to organizational adjustments | | |quickly. Especially (and this can be something to consider nowadays), this also enables us to | | |achieve substantial cost savings at the time of healthy diet a data middle. There will end up being | | |savings inside the electrical invoice, refrigeration costs, physical space, and components. | | |Moreover, deployment and disaster recovery will probably be much simpler. | |All of the will result in lower maintenance costs”whether we have our very own IT section | | |in 100 percent administration on this platform or possibly a virtualized environment of the IT | | |department (later, we will establish the THIS department price, as well as the choices and the | | |reasons behind virtualizing it). This all brings about there not being almost any circumstance in | | |which virtualization is not utilized and that will not cause a much lower TCO. | || | |Desktop Virtualization | | |In this regard, it is also possible to look for very well-developed and well-tested | | |technologies, just like Microsoft Terminal Server, Citrix, and so on. This kind of | | |virtualization was once thought about for remote factors or backlinks that had a | | |relatively tiny bandwidth.

Today, it is employed as a solution to reduce | | |desktop-administration expenses, mainly because (thanks for this technology) it will be easy | | |technically to acquire tolerance to failures, put it to the server-virtualization structure, and| | |create a pool of servers. There exists substantial decrease of the desktop-maintenance cost | | |and the cost of desktops themselves, because with products that has small hardware, this | | |is possible to run any kind of application but still have centralized control and | | |deployment of applications and security guidelines. | || | |Virtualization of the IT Division | | |In yesteryear, there was a low or not-so-significant THAT department cost, compared| | |to one nowadays. Today, there is a excessive IT division cost, in fact it is necessary to | | |consider the following variables: training in new technologies, trained in the company | | |environment, the cost of employees search, plus the time during which the search takes | | |place. All of this leads to the THAT department not being able to respond while using speed | | |that the company needs. In ddition, we presently experience an increased labor proceeds, which | | |means that many times this process has to start again”which, of course , pushes the cost | | |upwards. | | |If we all consider many of these factors, particularly the costs and the time the fact that search | | |involves, we will see that having a virtualized IT department results in a lower TCO and | | |in create advantage. With virtualization, all of these IT-department problems are | | |moved to a external firm that is specifically devoted to THAT, particularly mainly because it refers | | |to specialists in technology or in certain technologies.

This will mean that there is no| | |point in having a specialist as part of the inside IT office. | | || | |Cloud Computing | | |Currently, there an infinite number of solutions are available on the net, from email | | |services (as has been the advantages of a very very long time) to CRM, ENTERPRISE RESOURCE PLANNING, Document Managers, and | | |other services.

This solution naturally offers a new of advantages: It really is unnecessary to| | |have a specialist with this technology within our IT office, it is similarly unnecessary | | |to maintain that technology coming from either the hardware or perhaps the software standpoint, and | | |keeping security clones of the details is no longer needed. Depending on the kind of| | |hired support and service-level agreement (SLA), it will be possible to experience a redundant | | |and always-online services. In some cases, the cost for this kind of service can be | | |high”depending on both the range of users inside our organization who also require this kind of | | |service as well as the characteristics in the service”and will be worth considering. | || | | | | | | | | | | | | | | | | | | | | | | | | | |Example of Structure | | |(Example based on a company with 500 employees. ) | | |[pic] | | | | | |Figure 2 .

Current architecture | | || | |As a good example, we uses a virtualization architecture that uses such Microsoft | | |technologies as Hyper-V and Terminal Server. Number of servers: 12-15. | | |Typical composition of IT office: One director, two IT administrators, 1 database | | |administrator (DBA), and five Support Desk workers. | | |Based on everything that was explained recently, we will need the best of each | | |virtualization technology to carry out a cost reduction. | |Server Virtualization | | |It will be possible to minimize approximately 15 non-critical computers into 4 physical servers| | |that will be able to support these 12-15 virtual web servers. It will be important to carry out a| | |load analysis and distribute the servers and business applications correctly. Currently, | | |given the sort of roles of a typical company machine, there are only a few servers that contain | | |a excessive processing ingestion, thus, it can be necessary to separate these kinds of | | |servers, so that one competition discord is certainly not generated.

It will also be | | |necessary to include (if we do not have already it) another storage by which our | | |virtualization scheme will probably be stored (so that it is feasible to work on it in a cluster) | | |and which will have got tolerance to failure of all the virtual equipment. All of this will| | |be possible through the use of Microsoft Home windows Server 08 64 pieces and Hyper-V System Center | | |Virtual Machine Manager to handle the P2V conversions. | |Cost Reduction | | |Within this kind of example, you’ll be able to reduce about 70 percent from the energy | | |consumption, as a result of much less consumption on the part of the machines. In addition , | | |there will also be a discount of approximately 70 percent in the refrigeration | | |consumption, as a result of the use of storage space. | | |The licensing cost will likely decrease (when we use Microsoft licensing) very | | |substantially. The Microsoft licensing plan is based on Table 1 . In the table, we could | |see that by using Windows Server 2008 data-center server guard licensing and training, it will be possible to| | |obtain a reduction in guard licensing and training from 12-15 servers (which will be able to employ different | | |versions of Home windows Server 08, depending on the processor chip and RAM needs) to only 4 (with| | |data-center or business licenses). With respect to the versions of Microsoft Glass windows that | | |are used, in the least favorable situation, we will certainly achieve a lowering of cost of 55 | | |percent. | |Version of Windows Machine 2008 host | | |Covered electronic servers | | | | | |Standard | | |1 | | | | | |Enterprise | | |4 | | | | | |Data center | | |Unlimited | | | | | |Table 1 .

Microsoft Guard licensing and training Scheme | | || | | | | | | | |Desktop Virtualization | | |Depending around the memory usage of the applications, it will be possible to implement | | |approximately five digital servers to get Terminal Server” typically, in five physical | | |servers to cover 500 operate positions.

The main advantage of having virtualized servers can be | | |that this will likely automatically travel to any different, in case of a failure in any physical | | |equipment. | | |In this way, we are able to include a computer’s desktop with fewer resources, and it will be | | |possible to revise the applications more rapidly, just like deployment, administration of | | |printers, and any other desktop problem. In turn, this will also permit us to make the | | |desktop in the user open to remote or perhaps external users. | |Cost Reduction | | |If we consider, on the one hand, the expense of updating 500 desktops resulting from the | | |installation of several business software and, alternatively, the getting five | | |32-GB RAM computers and two Quad Core processors each, we can obtain a expense reduction of | | |approximately 80 percent. | | |Virtualization of the IT Department | | |It is first necessary to analyze the critical and noncritical applications, it is | | |important also to assess the IT labor marketplace in the country by which it is used. | | |Generally speaking, the suggestions that is provided is to virtualize whatever is difficult to get| | |in the market and have part virtualization with the IT office.

For this | | |example”and considering the current work market”we will opt to virtualize (for example) | | |only one THAT administrator and one DBA, the Help Workplace, one IT Administrator, and the IT | | |manager will continue to be physical. By having an SLA with exterior suppliers and a | | |framework work agreement, it will be possible to increase rapidly the IT office or | | |change swiftly the scheme without a great increase in initial costs. It will also become | | |possible to diminish training costs, hiring costs, and so on. | |[pic] | | | | | |Figure several. Virtual-server circumstance | | || | |Cost Reduction | | |If we consider the TCO, hiring costs, training costs, and incomes, we can obtain a cost | | |reduction of around 55 percent. | |Cloud Computing | | |Let us consider an application that wont be worth having internally, because of the size | | |of the business. For this case, we uses a CRM. Ten CUSTOMER RELATIONSHIP MANAGEMENT licenses will be hired | | |online. In this way, not any costs will be associated for the initial certification, administration | | |training, CRM storage space deployment, disaster-recovery policies, or anything that pertains to | | |administration of the CRM. | | |Cost Reduction | |Based in online providers, there will be a cost reduction of approximately 80 percent”based| | |on 10 permits, and considering the initial cost of having a machine, trained personnel, | | |backup guidelines, and so on. | | | | | | | | |Financial Benefits of Virtualization | | |. | |”Leveraging electronic computer environments has increased the opportunities intended for teaching and| | |learning. This particular solution is economical and lasting in many different | | |ways. Tech related costs have lowered by a very little over $250, 000 a year. That is a | | |combination of reduce software costs, app application costs, and increasing the life with the | | |hardware. That in turn minimizes the cost of the hardware can be 35-40% when they do | | |replace it.

Pcs can be restored with hardware that is much more cost efficient | | |because it does not need to be the latest and greatest equipment. The pcs that are | | |replaced cost about $500 or perhaps less. | | |IT staff amounts are straight down, mainly because of a reduction in LAPTOP OR COMPUTER technicians. Everything is | | |moving back for the data centre and, as a result of way they will implement all their | | |environment, every time a user accesses an application or a personal pc they are basically accessing a | | |copy of the perfect photo.

Every time you open up Word it is just a brand new fresh copy and when| | |you are done using it that image goes away so you are not really re-using it. SCC does | | |manage their profile information thus if they create custom made shortcuts it can be applied | | |over that online application. That way they nonetheless get that customized personal | | |environment. Gathering resources decreased hardware and software costs while stretching the | | |life of current hardware methods. This decreases the school’s total expense of ownership and | | |makes an extremely significant difference. | | |To read the associated with this survey, Desktop Virualization for the Real World, IMF people can| | |log-in | | | | | | | | | | | | | | | | | || | |Conclusion | | |The virtualization scenario means that we can make structural changes in the THIS | | |department together with the speed which the market actually needs. | | |We can possess strong cost reduction, because with a physical structure, we regularly do not employ | | |all in the resources”hardware, software program, employees, and so on”at completely.

On the other| | |hand, with virtualization we have the opposite case: All of us use and push the resource | | |utilization as far as likely, and then all of us add even more resources to virtualize. | | |In our model, we can see the consumer cost reduction, if we consider it globally, | | |however, the cost lowering is more significant. | | || | || |
