Overview

Virtualized application has transformed IT in such a way that it provides a streamlined approach to delivering Windows apps. This singly, centrally-directed app supports workforces based in every location and on any operating system, thereby boosting IT efficiency on top of performance.

Introduction


Years ago, transferring applications to the web promises straightforward growth cycles. Those promises never to hold true. Delivering browser-based apps while at the same time refining manageability and user aptitude, Web browsers causes countless indistinguishable glitches as some Windows app, from repetitive updates to compatibility concerns. Virtualized applications have had provided a simple way of delivering apps facilely and securely.

IT organizations, many years back, develop a series of advanced web apps for browsers and plug-ins that may have been outmoded today or may currently pose safety risks. Many of these were being turned off by vendors alike whether IT likes it or not. Of those web browsers that do remain viable still poses some of the same issues as some other standard desktop application, including repeated updates leaving developers small window to service. Challenges are multiplied by the many web-based browsers now in everyday use such as Chrome, IE (Internet Explorer), Firefox and Safari, plus Microsoft’s latest Edge browser, and the resulting matrix becomes overpowering.

Virtualized applications proffer a way to bring about the advantages of web-based apps without the downsides. By virtualizing a web-based app on a single browser configuration or version, and then, again delivering it the same manner to each user, IT then can solve compatibility issues while improving manageability and security.

Citrix Secure Browser deliverance of web apps presents three top benefits, namely;


1. Lessens development and supports the cost of browser-based apps
2. Lessens common security threats
3. Delight users with easy, crystal clear remote access experience.

Delivering web apps with the virtualized application, IT organizations can increase the same advantages of centralized delivery to this important type of applications. Application virtualization makes the application available to desktops, laptops, Remote Desktop Session Host (TST-Terminal Server) and server-hosted VDI platforms. The benefits of application virtualization include the following; delivery speed, the ease of application support and management, installation, upgrade, and rollback. The physical set up of applications is no longer required, thereby eliminating the possibility of conflicts, resulting in energetic application distribution set-up.

The three main reasons for delivering web apps with application virtualization

1. Cost reduction on development and support associated with browser compatibility problems

A virtualized browser enables an organization to significantly reduce web app management costs by streamlining app deployment and development management. App management centralization and swift provisioning help organization consolidate arduous jobs such as retrogression testing and shoving out app updates to align with every browser release. This will make much easier to dispense updates to the whole workforce, along with unfailing user know-how all throughout any device and browser, and can significantly lessen help-desk calls. Precisely as important, virtualization allows an unimpeded update to web apps without pushing costly device-side upgrades to support the provisions of the web applications operating system. Affordability aside, IT can further scale up and down fluidly and economically.

2. Focus on common security threats


A centralized application and data residing within the hardened data center add strata of network security. Not any data resides on the device and nothing stays behind as soon as the network connection is terminated, in the process, aiding security and compliance system. Keystroke commands, mouse click, and screen updates are only what traverses the network to the user’s endpoint device, extremely cutting the risk of data exfiltration or exposure. Granulose access strategy enforcement allows an organization to remove needless Virtual Private Network (VPN) holes and lessen the threat of data loss or incursion through unsafe connections.

3. Delight users with well-defined secured remote access


Lately, application layering has emerged as an alternate means to bundle and deliver applications separately from the operating system, without the need of reinstalling them on each desktop. Application virtualization removes the need for users to worry themselves with technical specifics, they can just launch any web app in any cutting-edge browser devoid of the need for a VPN and get to work right away, as there is no need to install anything on the endpoint device.

Outdated remotely access VPN can become a sticking point of seamless productivity, delaying and irritating users, exactly the same for the need of using a specific browser and a version of it to run a particular web app. The web app merely renders in a browser tab, purely like an outdated web app. In the meantime, all the data stays secure inside the data center, along with cache data, and in no way exposed to the threat on the endpoint. Business apps and data remain discrete from personal content, aiding IT to maintain policy and security control devoid of any meddling with the user’s personal apps and data on corporate and BYO devices. The competency of hosting browser apps in superfluous data centers helps ensure efficiency by streamlining business continuity.

Web-based apps frequently fail to live up to its perceive expectations


Web-based apps are nowadays an everyday element of many organizations’ IT policy - but in practice, web browsers can trigger lots of the similar problems as any Windows app, from frequent updates to compatibility concerns. The charm of web-based applications is simple to understand. The aspiration was to get rid of the necessity of developing and deploying a distinctive client for all app or to test across many operating systems by moving from legacy client/server apps to lightweight apps that are accessed by means of a web browser. Users would be able to access instead most of the apps from a web browser, as well as users using non-Windows platforms. These benefits have made web-based applications a mainstay of many organizations’ IT policy, although significant drawbacks still remain.
Web browsers can likewise lay bare the organization to security threats such as the inception of network communications, the loss or theft of downloaded data to the local computer and illegal access to web apps bookmarked in a particular browser. From a user standpoint, security requirements can cause obstacles to productivity, as the demand for the use of a VPN for isolated access points undermines the expediency that the web apps are expected to provide.

Though organizations will no longer have to agonize vis-à-vis the many operating systems, it does have to be concerned with ensuring the compatibility of web applications with several web browser its employees use. Frequently, organizations are compelled to keep on using out-of-date browser versions primarily because of the web application is written on them, a methodology that’s specifically complicated for legacy web browsers that are no longer supported. But even with the latest standard browser, there’s still a need to test it against Apple Safari, Internet Explorer, Google Chrome, Mozilla Firefox and now the Microsoft Edge, which accordingly differs significantly from one another. All of these browsers are often updated as well, even more often than time-honored thick-client Windows apps, adding up back a great deal of the development operating expense the organization sought to eliminate.

The answer to these problems are not the abandonment of the web-based development because of the merits of this methodology are still fundamentally fit, but rather, it needs IT to zero-in on the performance, management, and security problems of web apps so that it can deliver the full  worth for the organization.

Conclusion


Though web-based apps were instituted as a method to sidestep the deployment and maintenance problems of traditional client/server apps, its progress frequently ends up filling in for another set of problems. Nonetheless, an app is still an app, whether web-based or Windows apps, meaning that the very established advantages of virtualization for Windows apps are extendable as effectually to web apps, letting IT streamline app development and boost accessibility without incurring fresh challenges for manageability, security and user experience.
