Application Streaming: High-impact Strategies - What You Need to Know: Definitions, Adoptions, Impact, Benefits, Maturity, Vendors

Kevin Roebuck

Description

Application streaming is a form of on-demand software distribution.
The basic concept of application streaming has its foundation in the way modern computer programming languages and operating systems produce and run application code. Only specific parts of a computer program need to be available at any instance for the end user to perform a particular function. This means that a program need not be fully installed on a client computer, but parts of it can be delivered over the network as and when they are required.
Application streaming is usually combined with application virtualization, so that applications are not installed in the traditional sense.

This book is your ultimate resource for Application Streaming. Here you will find the most up-to-date information, analysis, background and everything you need to know.

In easy to read chapters, with extensive references and links to get you to know all there is to know about Application Streaming right away, covering: Application streaming, Absolute Manage, Amazon Machine Image, Software appliance, Application directory, AspectJ, Binary delta compression, Black Legend (software publisher), Code on demand, Commercial software, Eclipse Buckminster, Freightgate, Fully Automatic Installation, GetApp.com, Hybrid SaaS, Intellectual property brokering, Klik (packaging method), List of software package management systems, LitwareHR, M23 software distribution system, On-premises software, Operation: Bot Roast, Opsi, Organization of Independent Software Vendors, Personal Package Archive, Software package (installation), Package management system, Pre-installed software, Product bundling, Software publisher, Package development process, Software repository, Retail software, Self service software, Self service software vendors, Shovelware, Software as a service, Software broadcasting, Software deployment, Software distribution, Software manufacturing, Software propagation, Software remastering, Superdistribution, Virtual appliance, XCOPY deployment, Zero Install

Stream server [1] [2] An application isPackagedand stored on a streaming server.Packagingorsequencingproduces an image of [1] the application in a way that either orders delivery and/or predictively optimizes delivery to the client.

Launch & Streaming of Application The initial launch of an application would be important for the end user and the Packaging process might be optimized to achieve this. Once launched, common functions would be followed. As these functions are requested by [1] [2] the end user, these may be Streamed in a similar manner. In this case the client is pulling the application from the stream server. Otherwise, the full application might be delivered from the server to the client in background. In this case, the server pushes the application to the client.

Advantages Given the complexity of modern applications, many functions are never or seldom used, and pulling the [3] application on demand is more efficient in terms of server, client and network usage [2] ` Simplified operating system migrations [1] ` Accelerated application deployment [1] [4] [2] ` Centralised application management, with local execution [2] Ability to continue to use applications when off-line (in contrast to pure web-applications) Delivers fully featured desktop applications (in contrast to browser-driven web-applications) [3] Software license optimisation by controlling simultaneous users of software

School webcam controversy In the 2010Robbins v. Lower Merion School Districtcase, plaintiffs charged two suburban Philadelphia high schools secretly spied on students by surreptitiously and remotely activating webcams embedded in school-issued laptops the students were using at home, and therefore infringed on their privacy rights. The schools admitted to [6] [7] secretly snapping over 66,000 webshots and screenshots, including webcam shots of students in their bedrooms. LANrev software was used in the Lower Merion school district's student laptop program, overseen by network [8] technician Michael Perbix. In February 2010, Perbix and other administrators in the district were accused of using the software to take undisclosed and unauthorized photographs of students through the webcams on their Macintosh [9] laptops. The lawsuit was brought by the parents of 15-year-old sophomore, Blake Robbins, who was allegedly accused of illicit behavior seen through his computer's webcam of him in his bedroom. The photographs, taken from [10] a laptop that was reportedly not stolen, were then allegedly used as evidence in a disciplinary action. The FBI [11] [12] investigated the incident, and a Philadelphia federal judge intervened to sort out issues relating to the lawsuit. Perbix had previously praised Theft Track, the name of the feature that lets administrators remotely photograph potential thieves if a computer is reported stolen, noting in a Youtube video he produced that: It’excellent feature. Yes, we have used it, and yes, it has gleaned some results for us. But it, in ands an of itself, is just a fantastic feature for trying to—especially when you’re in a school environment and you have a lot of laptops and you’re worried about, you know, laptops getting up and missing. I’ve actually had some laptops we thought were stolen which actually were still in a classroom, because they were misplaced, and by the time we found out they were back, I had to turn the tracking off. And I had, you [13] know, a good twenty snapshots of the teacher and students using the machines in the classroom.

LANrev's new owner, Absolute Software staunchly denounced the use of their software for any illegal purpose, [14] emphasizing that theft recovery should be left to law enforcement professionals. They further denied any knowledge of or complicity in either Perbix's or the school district's actions. Absolute stated that the next update of [15] LANrev, which would ship in the next several weeks, would permanently disable Theft Track.

Amazon Machine Image

AnAmazon Machine Image (AMI)is a special type of virtual appliance which is used to instantiate (create) a virtual machine within the Amazon Elastic Compute Cloud. It serves as the basic unit of deployment for services [1] delivered using EC2.

Contents Like all virtual appliances, the main component of an AMI is a read-only filesystem image which includes an operating system (e.g., Linux, UNIX, or Windows) and any additional software required to deliver a service or a [2] portion of it. The AMI filesystem is compressed, encrypted, signed, split into a series of 10MB chunks and uploaded into Amazon S3 for storage. An XML manifest file stores information about the AMI, including name, version, architecture, default kernel id, decryption key and digests for all of the filesystem chunks. An AMI does not include a kernel image, only a pointer to the default kernel id, which can be chosen from an approved list of safe kernels maintained by Amazon and its partners (e.g., RedHat, Canonical, Microsoft). Users may [3] choose kernels other than the default when booting an AMI.
