distinguish between portability and compatibility as used in software selection

Portability - you can move the image where you want. What happens if your container expects a certain kernel module to be loaded and running? We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. Again, it can be difficult to deal with this and similar questions. Red Hat cannot guarantee that every permutation of Linux Container Image and host combination on the planet will work. Nor can Red Hat go patch and update every Linux container image thats out there. The docker daemon provides no compatibility guarantees any incidental compatibility is provided by the Linux kernel and Glibc. Many to-many Relationship, Most software developers are adopting object oriented analysis and design. Explain three typical features of these system that make them inevitable in organization, Explain the importance of pseudocode in system design, Outline three causes of project schedule slippage, Outline three limitation of using waterfall model in system management, With the aid of diagram, describe three types of relationships used in entity relationship diagram (ERD) Give differences between a CD-R and CD-RW. Reason: Versions Compatibility Requirements are non-functional requirements. Give two reasons for this. Compatibility - they are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). We are still in early days and havent ran into even a small percentage of the problems that we will as this technology ages when we are using kernels, container engines, and images which are of vastly different ages from built by Linux distributions which take wildly different approaches to building kernels and binaries, we will see more and more problems. Portable applications can be converted from one computer environment to another one. People from DXKB community will be more than happy. Download as PDF. The program code itself can also contain unportable things, like the paths of include files. Now, lets try and execute that Windows Nano image on Fedora: Notice that this image wont run because the image config is not compatible, even though the image layers are portable and cached locally. Their goals, approaches, and guidelines overlap significantly. Standardizing on this image format lets us build infrastructure like registry servers which can be used to store any container image, be it RHEL 6, RHEL 7, RHEL8, Fedora, or even Windows container images. compatability testing is also known as protability testing. At Red Hat, Scott McCarty is Senior Principal Product Manager for RHEL Server, arguably the largest open source software business in the world. compatability testing means testing team verifies build run. However, when you write 64-bit code, you should ensure that your code contains specific keywords . Why is it necessary to consider user needs when purchasing new software? Since the recent wave of containers are governed by open standards, essentially any container host can push or pull images to and from any container registry. Differentiate between volatile and non-volatile memory. The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. This is what vendors can support. Requirements that software must have a good performance in a network with parameters such as Operating speed, Bandwidth, and Capacity, etc. +38 093 252 99 56 Portability alone does not offer the entire promise of Linux containers. This is what determines if the binaries in the container image can actually run on the container host. Hardware is manufactured in factories. You don't want to have different behaviours on some platforms, you don't want to waste time adressing enviroment related configs. the second one can be directly run on any platform. Your email address will not be published. It's especially useful for customers that want to move to .NET but plan to stay on Windows, at least as a first step. Use case diagrams are popular in system analysis. c)Production of calendars and brochures: Outline two data capturing methods that could be used in an information system. To demonstrate, run a Red Hat Universal Base Image 8 (UBI) Container Image on a RHEL 8 Container Host: This demonstrates a completely supportable image and host combination, which is also compatible, and portable. Required fields are marked *. Users purchase systems from many vendors to implement the solutions they need. Requirements analysis 3. The difference between larger and smaller devices is such that detailed software operation is different; an application designed to display suitably on a large screen cannot simply be ported to a pocket-sized smartphone with a tiny screen even if the functionality is similar. Originally posted at: http://crunchtools.com/deeply-understanding-the-different-between-portability-compatibility-and-supportability/, At Red Hat, Scott McCarty is technical product manager for the container subsystem team, which enables key product capabilities in OpenShift & RHEL, skopeo --override-os windows copy docker://mcr.microsoft.com/windows/nanoserver:1903 containers-storage:mcr.microsoft.com/windows/nanoserver:1903, skopeo inspect containers-storage:mcr.microsoft.com/windows/nanoserver:1903, podman run -it containers-storage:mcr.microsoft.com/windows/nanoserver:1903, Error: unable to find user ContainerUser: no matching entries in passwd file, podman run -it --rm ubi8 cat /etc/os-release | head -n 4, Engineering compatibility with the Red Hat Universal Base Image, https://learn.openshift.com/subsystems/container-internals-lab-2-0-part-1, http://crunchtools.com/deeply-understanding-the-different-between-portability-compatibility-and-supportability/. The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. Portability you can move the image where you want. I have said it before, and I will say it again, containers are just fancy Linux processes. Engineering compatibility with the Red Hat Universal Base Image, https://learn.openshift.com/subsystems/container-internals-lab-2-0-part-1, http://crunchtools.com/deeply-understanding-the-different-between-portability-compatibility-and-supportability/, Recent technical articles & videos. The original meaning of 'portable' was 'costs less to convert to a new platform than it does to rewrite for the new platform'. Interoperability is "the ability of two or more systems or applications to exchange information and to mutually use the information that has been exchanged" [6] . This characteristic is composed of the following sub-characteristics: System software Application software Notice that Skopeo can download a Windows Nano Container Image, uncompress it, and store it in .local/share/containers/storage/ (rooteless in this case) even though this is on a Fedora Container Host: The image is now available in the local storage: The image is cached locally, but you wont be able to run it on Linux. In these cases there is usually no need for detailed adaptation of the software for the system; it is distributed in a way which modifies the compilation process to match the system. What happens when your container image expects to find a file in /proc, or /dev? Deployment 7. Software which is not portable in this sense will have to be transferred with modifications to support the environment on the destination machine. Lets analyze a few key log messages to see why. Collectively, they affect both the utility and the life-cycle costs of a product or system. Feel free to contribute. For the work required to make software portable, see. Development. The term "software testability" has two related but different meanings: on the one hand, it refers to the ease with which a given test coverage criterion can be satisfied; on the other hand, it is defined as the likelihood, possibly measured statistically, that a set of test cases will expose a failure if the software is faulty. Portability we can move the image anywhere we want. Expanding the scope of container images which are supported, increases the testing, analysis, and repair matrix at a non-linear growth rate. The ability for your service to maintain multiple running instances that work as a cohesive unit is paramount to its ability to support concurrent users at scale. In some cases, software, usually described as "portable software", is specifically designed to run on different computers with compatible operating systems and processors, without any machine-dependent installation. One-to many/ Many to-one Relationship Mobile Compatibility Requirements are Non-functional requirements? testing. Because Android is an open source project, any hardware manufacturer can build a device that runs the Android operating system. Notice that Skopeo can pull the Windows Nano container image, uncompress it, and store it locally even though this is on a RHEL 8 container host: The image is now stored in .local/share/containers/storage/ because its running rooteless in this case. As to whether there is a certain intersection between portability and compatibility between various platforms, the following discussion is carried out. So, if your dev team moves to different enviroment, you don't want to waste time and resources on re-development. Differentiate between portability with reference to hardware and software. It is possible to compile software for different operating systems and processors provided that it is written in a programming language that supports compilation for the respective platforms. Tin Can API is the successor to SCORM. Dont mix and match distributions and version its crazy talk. Mobility a)Polychromatic screen: This software is implemented on multiple platforms. With numerous kinds of processors with various design philosophies available at our disposal for . Differentiate between open source and proprietary software.

The Solaris operating environment is portable, scalable, interoperable, and compatible. When writing 32-bit code, you can use the 64-bit version of Office without any changes. I am here to break it to you its not magic. Overview. However, in many cases, the software is installed on a computer in a way which depends upon its detailed hardware, software, and setup, with device drivers for particular devices, using installed operating system and supporting software components, and using different drives or directories. In fact, registry servers based on the OCI distribution specification are so popular that theres a proposal to extend them to include almost any artifact: docker://mcr.microsoft.com/windows/nanoserver:1903 \, containers-storage:mcr.microsoft.com/windows/nanoserver:1903, skopeo inspect containers-storage:mcr.microsoft.com/windows/nanoserver:1903. Create more predictable projects. b)Management of a records in a firm: Programming 5. What do these symbols represent in a computer system? Define the following terms as used with monitor technology in computing. Such a folder has many sub-folders, and they are copied in the same transaction. c)Refresh rate: Sarah was required to select a system development method for a proposed information system for her company. Requirements that software must be compatible with different hardware configurations. The aim of this Guide is to provide a clear definition of interoperability and of portability and how these relate to various aspects of cloud computing and to cloud services. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). The SunOS 5.7 product is portable across multiple vendor platforms. This compatibility problem extends to processor architecture, and also versions of the operating system. To explain the terms then two basic entities are required: Components are one of the parts that make up a system, while a system is a collection of components organised to accomplish a specific function or a set of functions (both from IEEE 610). Learn how and when to remove this template message, modifies the compilation process to match the system, A Unix operating system for the DEC VAX-11/780 computer, "Bringing Portability to the Software Process", "Software Portability: Weighing Options, Making Choices", "Porting UNIX Software: From Download to Debug", https://en.wikipedia.org/w/index.php?title=Software_portability&oldid=1127113006, Short description is different from Wikidata, Articles needing additional references from November 2011, All articles needing additional references, Articles containing potentially dated statements from 2011, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License 3.0. True/False. Outline two responsibilities of a system analyst in an organization 2. For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 Yet, a device is "Android compatible" only if it can correctly run apps written for the Android execution environment. Compatibility is based on hardware architecture (x86 versus ARM), operating system (Linux versus Windows), Linux distribution (RHEL versus other distros), and even age of the Linux distro in the container image for example, very old images may not work on newer hosts, while very new images may not work on older hosts. If you have ever done a Gentoo Stage 1 install, then you know exactly why you run binaries that are designed for and built with the same kernel they run on. The standardized format of containers is what makes them portable between. Its fun to experiment and see what will work, but dont deploy production applications this way. Hardware is a set of physical parts of computers which actually executes the instruction. Devices Compatibility Requirements are functional requirements? Software Requirement Specification | Full form of SRS in Software Engineering, Space Requirements - Non Functional Requirements Example, Activity Diagram | Scenario and Case Study Base, Representing Use Case Diagram with SUC Table. Tons of technical people are out there showing demos of interoperability that doesn't explain the whole story, and in fact leads people down a really . A computer game that must work on Windows 7, Windows 8, and Windows 10. Judes intends to select a file organization method for an information system that he was designing for a client. For example, Google Chrome is compatible with Windows 10. To operate in a growing environment, software must be able to run in a wide power range and must be able to take advantage of the additional processing power. True/False. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); //mcr.microsoft.com/windows/nanoserver:1903 containers-storage:mcr.microsoft.com/windows/nanoserver:1903, "sha256:14b9bc111f8cd94dc0c807d4c4735d973d4d0c2138c61ae416c8f032c07dee89", "sha256:e145b606dfc22d200d5cb05f3ac1d69fdd0dd13b1e2d906c7ebaf154e6a694ed", Architecting Containers Part 1: Why Understanding User Space vs. Kernel Space Matters, DevConf.cz 2020: Brno: Understanding Container Engines by Demo, Deeply Understanding the Different Between Portability, Compatibility, and Supportability. With the aid of a diagram, describe two symbols used in use case diagram. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); DockerCon 2017: Austin: The Cube Interview, Why Portability is Not the Same Thing as Compatibility. It is verifying your software application to be compatible with different versions of the software. the registry on machines running Microsoft Windows). For Dev-ops, portability comes with stability. This means you can share infrastructure like registry servers between cloud providers or on-premise. Requirements that focus on the compatibility of our website with different browsers like Google Chrome, Internet Explorer, Firefox, Safari, etc. What is Software Compatibility Testing? Which software would you use for the following? Maintenance What factors affect the time it takes to the software development process? Walled gardens prevent data from being easily transferred. As languages evolved and vendor lock-ins reduced, it has since morphed to mean several things including binary compatibility and source-code compatibility. - Adaptability - Installability - Coexistence - Replaceability - Portability Compliance Notice that Skopeo can download a Windows Nano Container Image, uncompress it, and store it in .local/share/containers/storage/ (rooteless in this case) even though this is on a Fedora Container Host: The image is now available in the local storage: The image is cached locally, but you wont be able to run it on Linux. (i)Identify the training method that he would be using Differentiate between USB and SCSI ports. True/False. Supportability: It helps in maintaining the testability, extendibility and correctability. -Hardware portability refers to the ability to carry a computer from one place to another while software portability is the ability to copy/install the software in more than one type of computer. Sometimes the effort consists of recompiling the source code, but sometimes it is necessary to rewrite major parts of the software. Outline four factors that he should consider in the selection, other than cost. Portability - we can move the image anywhere we want. Building executable programs for different platforms from source code; this is usually called porting. For example we got this error trying to install a music interface device driver for home recording. Porting is no more than transferring specified directories and their contents. What degree of portability is desired for the various environments? Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. First, the work of organizing and creating a container is done in user space. The examiner could want to establish whether you can differentiate between hardware and software portability; Another major development in this question is the word portability. Describe knowledge based system 4. Software is developed or engineered; it is not manufactured in the classical sense. It implies that the data are in electronic files that are readily accessible rather than only visually on a screen. Standard operating environment . What happens if your container does more than just file open(), say it needs access to dedicated hardware? ! Thats true, it does work most of the time, but I would like to highlight some questions I have ran into over the last 4-ish years, working with docker, and talking to literally thousands of people about the problems they see: Well, do you have an answer for each of the above questions?
