Remotely Deploy Apps across a LAN

EMCO Remote Deployment Kit allows you to install or uninstall applications silently and remotely across your LAN. You can even view a detailed list of applications deployed across various systems

Mass deployment of applications across a LAN is a laborious task that deviates time and resources from other crucial tasks. Let's suppose, a new anti-virus solution needs to be deployed. While doing so, it has to be ensured that all user machines have been updated. Normally,one would need to visit each machine individually and install the required anti-virus application. which is a really laborious task. To help ease out such monotonous and time-consuming tasks, remote application deployment is the need of the hour. It helps you to remotely install or uninstall routine applications on user machines silently, ie, without bothering the user.

There are quite a few remote deployment software available that allow you the luxury of doing such tasks quite effortlessly. EMCO Remote Deployment kit is one such software in this domain. Here, we guide you on how to achieve mass application deployment using this software. It costs around $165 (INR 8250 approx) for 100 nodes. The software can be used to deploy all the routinely used applications such as Acrobat Reader, WinZip, Real Player, MacAfee, Norton anti-virus, MSN messenger, etc. In addition, you can build a deployment kit for your own applications.

A big advantage of this software is that you don't have to keep the setup files in the repository. You simply need to install the software on thedeployment machine. Before getting into details, let's build a scenario, so that you can understand the implementation process easily.
We assume that the organization is using active directory for user authentication and all the machines are trusted in a domain. Plus, all machines are using Windows OS.

Step 1: InstallationTake a Windows XP/2000/2003 based machine as your deployment machine. Register this machine with your domain controller and install EMCO Remote Deployment kit on it. You can download a 30-day trial version from the link provided. Once you have installed the software, rebootthe machine. Identify frequently used applications in your organization and install them on the deployment machine. Here, we installed Acrobat Reader, Real Player and Norton anti-virus. These are typical applications across workstations in an organization.
Select the machine where you want to deploy the application from the Machine Tree on the left. Drag it to Machine Queue window on the right

Step 2: Using EMCO Launch EMCO Remote Deployment Kit from the deployment machine that you have created. Its console is divided into two parts. The left panel shows you details of all the scanned machines across the LAN. The right panel shows remote deployment jobs in queue. On the same panel, at the bottom, you will find an Install/Uninstall button, where you need to select the application, for remote deployment. Now, go to the left panel and click on 'Enumerate LAN.' This will start the scanning of all machines on your network. You can even scan on the basis of domain and range of IP addresses. Once you get the list on the left panel, select the machines and drag and drop them to the right panel. With this, the EMCO deployment kit is ready to use across the selected group of machines.
Before installing/uninstalling any application on a remote client, you will be shown an application list. The ones with a green dot can be deployed while those with a red can't

Step 3: Application deploymentNow, select the application that you want to deploy on the target machine. In the right panel, click on 'Install/Uninstall' button. You will get a list of applications that EMCO can deploy on the target machines, remotely. If you look carefully, you will find green and red dots in front of application names. The applications with green dots denote that the application already exists or has been installed on the deployment machine, and so can be deployed on the remote machines. Whereas red ones denote that these applications are not installed or do not exist on the deployment machine, and hence can't be deployed. Therefore, you can only select applications with green dots.
This window shows a detailed analysis of all remote machines. You can see the number of drives, OS names, protocols, Mac addresses, etc for each machine
After this, click on the Install button. This will start the deployment process. Once the deployment process is complete, you will get a 'successful completion report' with a list of changed parameters on the remote machines. Finally, on the remote machine, check the status of the deployed application.
Note: In windows XP sp2 workstation, you have to add ports in the exception list of the Windows firewall. Add the ports 136, 139 and 445.

Preface


Linux open source based implementation gives a new dimension to the web based implementation, now the software industry is moving from the client based access to the internet technology adaptation which given birth to Yahoo, Google, Gmail and other companies to redefine the business stragedy for next generation computation and the fittest will survive for the same,
Advantages of Linux include: no license or royalty costs, full control over your project, no vendor lock-in, you decide on the priority of bug resolution, full access to all source code (with the right to publish, adapt and recompile the code), in terms its gives the ROI in the first implementation phase only. Squirrelmail is a web based mailing solutions which uses the technology advancement of LAMP (Linux, Apache (web server), Mail (Send mail Server) and PHP,
SquirrelMail is a standards-based webmail package written in PHP4. It includes built-in pure PHP support for the IMAP and SMTP protocols, and all pages render in pure HTML 4.0 (with no JavaScript required) for maximum compatibility across browsers. It has very few requirements and is very easy to configure and install. SquirrelMail has all the functionality you would want from an email client, including strong MIME support, address books, and folder manipulation and much more features to be added in next few years to come

Defining Return on Investment (ROI) Return on investment (ROI) is a key financial metric of the value of business investments and expenditures. It is a ratio of net benefits over costs expressed as a percentage. This formula can be expressed as: ROI = [(Monetary Benefits (Tangible and Intangible) - Cost of using Web Services Technology) / Cost of using Web Services Technology] x 100 An Example of ROI Calculation As an example, the IT group within a company determines that there is a 10 percent increase in the automation of software development following the implementation of Web Services for an organization's IT project. Other data from the IT group reveals that each one percent increase in the automation of software development is equal to increased annual revenue of 25,000. Furthermore, it is known that the Web Services implementation will cost 75,000. For this example ROI is calculated as follows: [(250,000 - 75,00) / 75,000] x 100 = 233% That's 25,000 for each one percent increase, for a total of 250,000 for a ten percent increase. This means that for every 1 invested in the Web Services implementation, the organization realized a net benefit of 2.33 in the form of increased revenue from the automation of software development. Payback PeriodROI is just a percentage, so include the payback time to make it persuasive. For example, if a 100,000 investment in Web Services technology is generating 400,000 a year in profit, it pays for itself within three months. Costs divided by monthly benefits yield the number of months to payback. Discounted Cash Flow Analysis In the discounted cash flow ROI analysis methodology, the expected cash flows relating to investments for a new technology or IT-related project spanning several years are discounted using an appropriate rate to determine an NPV and/or IRR. If the NPV is positive, then the project's present value exceeds its required cash outlay, and the project should be undertaken. When a project has a positive NPV, the NPV decreases as the discount rate used increases. Similarly, if the IRR is greater than the cost of capital for the company, then the project should be undertaken. Payback Period Analysis In the payback period ROI analysis methodology, the period of time it takes for a new technology or IT-related project to yield enough returns to pay for the initial investment, or to break even, is considered.
ROI Analysis Becoming a Necessity . ROI analysis is gradually becoming a core requirement for the kick off of any new project or use of new technology, as well as for measuring the success or failure of any existing project. A good ROI analysis can lead a new project or introduction of any technology to lower costs, improved business performance, and competitive advantage. ROI and Web Services A company should calculate the implementation and ongoing costs associated with Web Services including software, hardware, system integration, and future production support expenses. These cost estimates should be carefully examined to determine the ROI for the proposed solution. ROI Not Just About Technology Whatever the underlying technology for which ROI is being calculated, there is always a set of business and personnel factors that have a great impact on it. We cannot stress enough the fact that technology alone will not produce the quantifiable results and benefits as projected in any ROI matrix or calculation. Several business factors, such as the speed of rollout and systems adoption rate, play a critical role in determining the final numbers. Calculating ROI of Web Services How do you measure the ROI of Web Services? Well, there is a right way and a wrong way to measure ROI. The wrong way is to measure the time representatives save in reduced paper work, or in revenue the company saves by reducing the need for data entry. The right way is to measure the amount of reduction in operational and developmental costs. The ROI on Web Services comes from the increased operational efficiency and reduced costs that are achieved by streamlining and automating business processes, reduced application development cycle time, and increased reusability of applications in the form of services. Factors to be included in ROI calculation The relevance and importance of each of these factors will greatly vary from company to company, application to application, and implementation to implementation. If all these factors are considered together, however, you can get a pretty decent result from the ROI model used for Web Services. The factors we will look at are: • Costs and expenses. • Technical benefits. • Business benefits. Costs and Expenses These factors break down into the following elements: • Hardware requirements • Software requirements • Training requirements • Network bandwidth requirements • Monitoring tools • Operational costs and vendor consulting • Collaborative business activities
There may be other direct and indirect benefits for the usage of Web Services, such as faster time to market, increased process efficiency, and increased efficiency through business process automation. These also have to be accounted for in your ROI calculation.
ROI and Risk Management These factors break down into the following elements: • New technology • Standards not matured or finalized • Web Services development tools and servers • Services Security

Conclusion

Web Services run through industry standard protocols and offer the potential of eliminating the need for proprietary hardware, software, and network protocols. Companies will be able to lower their investment costs greatly in terms of increased ROI by implementing Web Services. There is no fixed model for calculating ROI of Web Services as of now, and the ROI in each company would greatly depend on how the technology is actually employed in solving software and business processes related tasks. Any model used for calculating ROI should take into account the risks associated with the usage of Web Services.
