distinguish between portability and compatibility as used in software selection

It would seem, that even Docker agrees, as they developed the Moby project andLinuxKit to be able to tightly couple these three things (host, engine, image) in what amounts to essentially a Unikernel like structure. 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. Your email address will not be published. It is most effective to address them together when designing and developing websites and applications. Planning 2. - Adaptability - Installability - Coexistence - Replaceability - Portability Compliance What happens when your container image expects to find a file in /proc, or /dev? It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. Again, it can be difficult to deal with this and similar questions. Standardization and clear interfaces are critical to a heterogeneous environment, enabling users to develop strategies for communicating throughout their network. This is a compatibility problem, even though the image is portable and can be copied to a Linux container host. You want to deploy your application as a containerized application using containers such as docker. Outline four possible causes of the failures. State two advantages of general purpose software. Mobile Compatibility Requirements are Non-functional requirements? a)Polychromatic screen: The comparison table is a much more versatile tool than . For instance checking your Microsoft Word to be compatible with Windows 7, Windows 7 SP1, Windows 7 SP2, Windows 7 SP3. Describe two key components of a term_of_refference document in information system projects. The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. First, the work of organizing and creating a container is done in user space. 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. It is to determine whether your software application or product is proficient enough to run in different browsers, databases, hardware, operating system, mobile devices, and networks. In this video, i am going to describe the Difference Between MOBILITY and PORTABILITY mobile computing? Portable data can be moved from one database or repository to another. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Operating Systems Compatibility Requirements are functional requirements? First, notice that Podman, DEBU[0000] mounted container "8be871d404f1a15410c63bf7b39f13a87aff4d87fbac5847c526029c802c9131" at "/home/fatherlinux/.local/share/containers/storage/overlay/1449c977519500a8939aaf49d28124c11b113b357922a33e341822e0429477af/merged", DEBU[0000] ExitCode msg: "unable to find user containeruser: no matching entries in passwd file", ERRO[0000] unable to find user ContainerUser: no matching entries in passwd file, If you would like to see another example of compatibility problems, even between very similar Linux distros, see, Supportability is about putting a reasonable scope around what is and isnt covered by a, To demonstrate supportability, lets run some tests with a container image called, podman run -it --rm ubi8 cat /etc/os-release | head -n 4, So, if you are using Red Hat Enterprise Linux today, and just getting started with containers, check out Red Hat Universal Base Image, its portable, compatible, and the most supportable base image available for RHEL and RHEL CoreOS. Can you say to yourself, honestly, yeah, I can fix that no problem? I have seen all of the above happen, and this is just the beginning. How is it that all of this just magically works? 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. Versions Compatibility Requirements When writing 32-bit code, you can use the 64-bit version of Office without any changes. As workloads expand beyond simple web servers which really only need to use system calls to open files and open TCP sockets, we will see more and more problems. Compatibility is based on hardware architecture, operating system (Linux versus Windows), distribution of Linux (Ubuntu versus RHEL), and even age of the Linux distro in the container image (very old images may not work on newer . That means x86_64 containers must run on x86_64 hosts ARM containers must run on ARM hosts Microsoft Windows containers must run on Microsoft Windows hosts. All rights reserved. Intel technologies may require enabled hardware, software or service activation. This means you can share infrastructure like registry servers between cloud providers or on premise. // Intel is committed to respecting human rights and avoiding complicity in human rights abuses. Requirements analysis 3. Software portability is a key concern when configuration settings affect software correctness and target operational environments are highly configurable. c)Antivirus. The above graphic shows all of the moving parts in a typical Kubernetes environment. Portability defines the ability to physically move software or . 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. Differentiate between portability with reference to hardware and software. Devices Compatibility Requirements are functional requirements? Differentiated between user guide manual and technical manual as used in system documentation, Outline two participant that could be invited for a structured walkthrough meeting, Outline three reasons that could influence a system designer to use functional decomposition, Decision trees are commonly used by system analyst. Click on each book cover to see the available files to download, in English and Afrikaans. Software design and prototyping 4. True/False. This addresses the content inside the container image. Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. In open-source environments such as Linux the source code is available to all. This is usually a task for the program developers; typical users have neither access to the source code nor the required skills. c)Production of calendars and brochures: A computer program is said to be portable if there is very low effort required to make it run on different platforms. As mentioned before, this is to be expected because container images are platform neutral (theyre just tar files) and governed by open standards, so Linux can uncompress it and mount it: The ContainerUser is a Windows user which Podman doesn't find in a passwd file in the image. Differentiate between USB and SCSI ports. A computer program is said to be portable if there is very low effort required to make it run on different platforms. Outline three strengths of this tool that could be influencing this trend, Robert intends to train users of a new system using an online program. And other updates in Red Hat Runtimes, Infusing your UX writing with brand personality. Your Red Hat account gives you access to your member profile and preferences, and the following services based on your customer status: Not registered yet? Deployment 7. All of the above MCQ 2: Compilers, Editors software come under which type of software? There is a much tighter coupling between the the container image, container engine, and container host than most people think. Such questions are not always easy to answer. List three factors that determines the cost of a computer. Learn how to get started with our official documentation. . (a)Production of report for a company: A computer game that must work on Windows 7, Windows 8, and Windows 10. Red Hat cannot guarantee that every permutation of Linux Container Image and host combination on the planet will work. Working closely with customers, partners, engineering teams, sales, marketing, other product teams, and even in the community, he combines personal experience with customer and partner feedback to enhance and tailor strategic capabilities in Red Hat Enterprise Linux. Your Red Hat account gives you access to your member profile, preferences, and other services depending on your customer status. Were the worlds leading provider of enterprise open source solutionsincluding Linux, cloud, container, and Kubernetes. Replication (deep) The first dimension of portability is crucial to operating cloud applications at scale - scaling and replication. 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] . The Windows Compatibility Pack sits on top of .NET Standard and provides access to these Windows-only technologies. One-to many/ Many to-one Relationship Lets demonstrate that the container image format is the same no matter which type of artifact we pull by pulling a Windows Nano image down on a RHEL 8 container host. Nor can Red Hat go patch and update every Linux container image thats out there. It would expand the testing and analysis matrix at a non-linear growth rate. As languages evolved and vendor lock-ins reduced, it has since morphed to mean several things including binary compatibility and source-code compatibility. on customer expected platforms or not. They dont understand the Unix design principles. Standard operating environment . This is about investing in testing, security, performance, and architecture as well as ensuring that images and binaries are built in a way that they run correctly on a given set of Container Hosts. Requirements that focus on the compatibility of our website with different browsers like Google Chrome, Internet Explorer, Firefox, Safari, etc. Portability - you can move the image where you want. Many language specifications describe implementation defined behaviour (e.g. Required fields are marked *. System software Application software 1. Hardware- and software-specific information is often stored in configuration files in specified locations (e.g. Define the following terms as used with monitor technology in computing. Differentiate between open source and proprietary software. If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. Last Updated: 04/11/2022. What do these symbols represent in a computer system? Give two reasons for this. Rather than using Java, HD DVD (the defunct high-definition successor to DVD) used a technology jointly developed by Microsoft and Disney called HDi that was based on XML, CSS, JavaScript, and other technologies that are comparable to those used by standard web browsers . Differentiate between portability with reference to hardware and software. supports H/W technology devices or not. Which distributions of Linux work together and who is testing this? For example, Red Hat supports RHEL 6, UBI 7, and UBI 8 container images on both RHEL 7 and RHEL 8 Container Hosts (note that RHEL CoreOS is built from RHEL 8 bits). You don't want to have different behaviours on some platforms, you don't want to waste time adressing enviroment related configs. Here the brevity of the lines of code is important. 5G core adoption the open way with Red Hat OpenShift, Whats new with Quarkus? For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 There are two types of compatibility: device compatibility and app compatibility . Devices Compatibility Requirements It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. The crotchety old systems administrator in me says kids these days dont understand the user space and kernel split. When a hypervisor is used on a physical computer or server (also known as bare metal server) in a data center, it allows the physical computer to separate its operating system and applications from its hardware. If you are a RHEL 7.3 shop, do the same thing. Better than just free, these books are also openly-licensed! 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. compatability testing is also known as protability testing. What degree of portability is desired for the various environments? Software doesn't "wear out". Their goals, approaches, and guidelines overlap significantly. In practice the claim of languages, like C and C++, to have the WOCA (write once, compile anywhere) is arguable. And, we have two types of version compatibility testing, which are as follows: Forward Compatibility Testing: Test the software or application on the new or latest versions. This software vendor evaluation guide will help your business navigate the software selection labyrinth. Browse Knowledgebase articles, manage support cases and subscriptions, download updates, and more from one place. Functional Requirements in Software Engineering are also called Functional Specification. Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. Stated another way, scoping support for container images can be very expensive. Building executable programs for different platforms from source code; this is usually called porting. Operating system functions or third party libraries might not be available on the target system. Research statistics indicates high rate of system project failures. Reason: Browser Compatibility Requirements are non-functional requirements. The Docker daemon or CRI-O, for example, is one of the many user space tools and libraries that talk to the kernel to set up containers. This also allows you to share infrastructure like Registry Servers. Try running a RHEL 8 container image on a RHEL 4 container host -- that isn't going to work very well. This means you can share infrastructure like registry servers between cloud providers or on-premise. Differentiate is the major keyword in this question. i) Describe the type of maintenance that you would recommend for the information system. While achieving portability is key for a wide range of software types, it is particularly important in Web application development. Study with Quizlet and memorize flashcards containing terms like Another name for data that has meaning is: - mean data - wisdom - information - none of these is correct - data accuracy, The difference between wisdom and knowledge is that: - none of these is correct - wisdom is the synthesis of experience, insight, and reflection - wisdom is the result of data collection and interpretation .
