Application Delivery Fundamentals

Executive Summary

With cloud revolution, application streaming, VDI and hosted apps have taken center stage. Office desktops that host applications have become a thing of the past. Earlier, IT specialists had to be on their toes, installing applications and updating them on a regular basis.

Applications are essential to the work environment. Businesses of all sizes need to have constant access to their applications, to keep the wheel turning, whether in the office, or while working remotely.

Application Delivery FundamentalsApplication virtualization is an easy way to manage, distribute and maintain corporate applications. Virtual applications run on a server while end users view and interact with their applications over a network via a remote display protocol. Remote applications can be completely integrated with the user’s desktop so that they appear and behave as local applications. Today, there are several ways to dynamically publish applications to remote users. The server-based operating system instances that run remote applications can be shared with other users (a terminal services desktop), or the application can be running on its own OS instance on the server (a VDI desktop).

Application virtualization also reduces the risk of data loss. In fact, information security is still a significant challenge for enterprises. On a daily basis, cybercrime menaces organizations by exploiting the vulnerabilities exposed in applications and technologies.

While the defense to each endpoint is costly and ineffective, a solution such as Parallels Remote Application Server  replaces traditional application deployment with on-demand application delivery. Hence applications are securely delivered to users, regardless of the operating system, from anywhere with any device. Instant encrypted access to applications is guaranteed while ensuring the highest levels of security and control over sensitive data stored on the server.

Applications Anywhere, at Any Time, on Any Device

As technology advances and the dynamism between applications, OSes and devices dramatically evolves, enterprises have no choice but to keep up. This means ensuring that employees can access the application they need, whenever they need it, and from whatever device they are working on. This creates an array of challenges for organizations: from providing consistent user experience across devices and OSs, to maintaining data security on the fly.

Application Delivery FundamentalsIn the current business landscape, a majority of employees are asking to work remotely or to have access to their corporate application on the move.  With the massive adoption of tablet and smartphone, this trend (of employees asking to work remotely) continues to rise, hence creating a lot of challenges. For example, when people are using their own devices to work, they would like to access local printers, application and files. However, it’s not even guaranteed that their device can run the applications they need, thus creating inconsistent user experience. Another challenge is ensuring security, especially when working with sensitive data.

In the stand-alone desktop era, IT specialists had to manually install applications on each device. For every update or a patch, they had to visit each device again. While it was a cumbersome task to handle many devices, downtimes were frustrating. Nonetheless, the advent of server technology brought a bit of relief to the IT staff. They were able to perform installation and updates to a group of workstations. However, to apply updates and patches to each workstation or group, they had to make sure each application was installed on each device.

Industry technology leaders agree that the latest advancements in desktop and application virtualization technology can help overcome many of the modern business IT challenges, and meet the changing needs of organizations. Cloud revolution has brought a centralized management system which means IT specialists can install applications on a server and publish them to remote users. Any update to the application residing on the server is instantly reflected on the remote desktop. As end-users access applications from the remote server, businesses are able to deliver high-end technology at cost-effective prices.

Application Delivery Options

Application delivery can be achieved in different ways. The most common way is hosting the software on a server and then publish virtual resources dynamically on the network. With the progression of innovation, application delivery Application Delivery Fundamentals Parallels RASgets new options. You can create a virtual desktop infrastructure or use Microsoft RDSH to centrally host applications. The action to establish a link between the host and the end users is assigned to a software defined as a “connection broker”. This is a critical part of a cloud solution and also the component that is often overlooked.  A connection broker performs a number of tasks which vary from broker to broker. At its most basic level, a connection broker is a traffic cop; it directs incoming connection requests to an available hosted resource. More advanced solutions offer an extra layer of security encapsulating the RDP traffic inside an SSL, dual authentication, high availability and workload load balancing. An efficient connection broker should enable employees to work virtually from anywhere,  supporting any device or operating system. Many solutions also allow access to corporate applications through an HTML5-compatible browser.

In order to guarantee consistent end user experience across different devices, the software should allow employees to use local peripherals such as printers, scanners and drives while working in the virtual environment. With an efficient peripheral redirection, a print job, for example, is launched on the application hosted on the server and is redirected via the network to a local printer. Likewise, to guarantee solid user experience at anytime, audio, drives, keyboard and mouse run smoothly on the hosted applications and locally.

By offering virtual application and a strongly integrated native experience, the workforce is able to access their applications at any time, anywhere, and from any device. In addition, when it comes to supporting a variety of devices, all of the processing is done in the data center, hence everyone has the same user experience. Furthermore, it is possible to run a complex graphic application even on a Chromebook or Raspberry Pi, by using a virtual desktop, because all of the processing and GPU acceleration is happening remotely in the data center, hence there is no need for local processing capabilities to get work done.

For instance, virtualization tools such as Parallels Remote Application Server, VMware Horizon  and Citrix Xenapp allow you to host applications on the server and seamlessly deliver them to end-users. However, the end-user only accesses the application on the centralized server and not on the local desktop.

Benefits of Application Delivery

Higher security, higher availability and higher  compatibility are the three important attributes of cloud-based application delivery. In addition, it reduces several headaches and challenges posed by traditional application delivery methods.

Reduces Downtime

As application delivery controllers have the ability to efficiently route the traffic between two or more routers, servers, firewalls or other network resources, application performance is improved while the downtime is reduced. Efficient virtualization solutions such as Parallels RAS not only checks for available servers but also identifies available gateways to ensure that the end-user is connected to a server that offers the best possible performance.

Reduces Installation Updates

The modern application delivery model simplifies installation and deployment procedures. All applications are installed on the server and remotely published to client devices. Updates and patches are made on the server; while end-users always access the most updated application. Customers don’t have to download or install any patches or updates. With reduced hardware and software infrastructure, enterprise IT costs are lowered.

Easy to Manage

Application delivery offers a centralized management system which enables you to effectively monitor and manage the entire infrastructure from a single dashboard. With reduced hardware, fewer people are needed to manage it. You don’t have to deal with updates, patches and other maintenance problems as they are handled by the cloud provider. This simplified IT infrastructure makes your job easier.

Deliver Any Windows Application to Any Device

Another benefit of application delivery is that you can deliver any windows application to any remote device. For instance, MS Office can be remotely published to an iPhone, Android phone or even Chromebooks. It provides seamless and consistent end-user experience across all devices.

Reduces Costs

Application delivery model allows businesses to optimize resources to the core. As applications are installed on the server and remotely published to client devices, businesses can save significant amounts on hardware and software purchases as well as on windows licensing. At the same time, simplified IT infrastructure requires fewer support staff and reduces downtime as well. Most importantly, initial investment is not required as you only need operational expenses.

Application Delivery Challenges

Application delivery is more vital than ever — and also very challenging.  End users want performance with a seamless experience, while CIOs are more focused on management and security at a reasonable cost.
