distinguish between portability and compatibility as used in software selection

The portability and compatibility of the ten external quality factors of software are somewhat confused at the beginning, and the definitions of these two properties are partially similar. Would you run binaries from different Linux distributions in production? Hardware is a set of physical parts of computers which actually executes the instruction. 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. A computer program is said to be portable if there is very low effort required to make it run on different platforms. Portability is a characteristic attributed to a computer program if it can be used in an operating systems other than the one in which it was created without requiring major rework. Explain three features associated with this methodology, Define the term resource as used in project management. True/False, Browser Compatibility Requirements are functional requirements? Give differences between a CD-R and CD-RW. Planning 2. This page was last edited on 12 December 2022, at 23:50. Second, there is no layer of abstraction, like virtualization. Compatibility can refer to interoperability between any two products: hardware and software, products of the same or different types, or different versions of the same product. Many language specifications describe implementation defined behaviour (e.g. Judes intends to select a file organization method for an information system that he was designing for a client. If you wanted to, you could even mix binaries from multiple different hardware architectures or operating systems in the same container image. Outline four possible causes of the failures. the registry on machines running Microsoft Windows). b)Resolution: They can be used to compare similar items from the same organization, or to compare one organization's products against those of a competitor. With regards to Windows apps, such programs would not use the Registry. Portability - we can move the image anywhere we want. List three precautions to take when handling a diskette. ARM binaries in a container image will not run on POWER container hosts - Windows Nano binaries in a container image will not run on a RHEL 8 container host. Well, it means two very important things. Sometimes the effort consists of recompiling the source code, but sometimes it is necessary to rewrite major parts of the software. Kubernetes is the future: But what does this future look like? In this video, i am going to describe the Difference Between MOBILITY and PORTABILITY mobile computing? A thorough examination of the differences between products will ensure you're getting exactly what you needno more, no less. The pre-requirement for portability is the generalized abstraction between the application logic and system interfaces. This is usually a task for the program developers; typical users have neither access to the source code nor the required skills. As new technology is introduced, there is a need for the existing software investment to be preserved. Manage your Red Hat certifications, view exam history, and download certification-related logos and documents. Accessibility, Usability, and Inclusion. For example we got this error trying to install a music interface device driver for home recording. So, if your dev team moves to different enviroment, you don't want to waste time and resources on re-development. The Solaris operating environment is portable, scalable, interoperable, and compatible. Give three items that should come along with an authentic software. True/False, Versions Compatibility Requirements are functional requirements? What do these symbols represent in a computer system? 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. The answer is.no. To summarize, with Podman on a RHEL 8 container host, running a UBI 8 container image, you get: Portability - you can move the image where you want. Freda Rose, Container Portability: Part 3 - Crunch Tools, When it comes to code, be a consumer - Keyrox, When it comes to code, be a consumer | Smart Solution 4.0, When it comes to code, be a consumer - MusicCosmoS, How to Buy a Used Linux Container - Crunch Tools, BrightTalk 2022: Virtual US: Upgrading to RHEL 9 (and Beyond) with Containers, Upgrading from PHP 7.2 to PHP 7.4 with Red Hat Universal Base Image, Deeply Understanding the Different Between Portability, Compatibility, and Supportability. How is it that all of this just magically works? Reason: Versions Compatibility Requirements are non-functional requirements. Portability in high-level computer programming is the usability of the same software in different environments. Containers do not offer compatibility guarantees; only virtualization can do that. They do the following at least: Provide an API prepare data and metadata for runc. With Podman running a UBI 8 Container Image on a RHEL 8 Container Host, we have: If you would like to understand Portability, Compatibility, and Supportability, check out this lab: https://learn.openshift.com/subsystems/container-internals-lab-2-0-part-1. One-to-one Relationship True/False. Hardware is manufactured in factories. In the simplest case, the file or files may simply be copied from one machine to the other. Answer / sampathi kotla. 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. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. We are happy you want to contribute to DXKB. Such a folder has many sub-folders, and they are copied in the same transaction. Differentiate between legal and operational feasibility studies, Mobile developers employ prototyping to solve user problems. This is important because recent versions of Microsoft Word have new features that aren't compatible with older versions. c)Production of calendars and brochures: To demonstrate supportability, lets run some tests with a container image called Red Hat Universal Base Image 8 (UBI) and a container host based on RHEL 8 Server: This demonstrates a completely supportable image and host combination, which is also compatible, and portable. 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) Within the cloud computing context this refers to the capability of public and private clouds to use an agreed language to use each others' access interfaces and to transmit data in machine to machine communications. b)Compressor When operating systems of the same family are installed on two computers with processors with similar instruction sets it is often possible to transfer the files implementing program files between them. The comparison table is a much more versatile tool than . 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 in OpenShift is built from RHEL 8 bits). If you're truly gung-ho on interface . With numerous kinds of processors with various design philosophies available at our disposal for . Describe three advantages of the tool that could be influencing this trend. All of the above MCQ 2: Compilers, Editors software come under which type of software? Try running a RHEL 8 container image on a RHEL 4 container host -- that isn't going to work very well. As long as I run the docker daemon on all of my hosts, everything will just work right? This is a compatibility problem, even though the image is portable. Learn how to get started with our official documentation. // Performance varies by use, configuration and other factors. Also, high-quality support is based on a well defined and scoped set of components that are designed and engineered to work together. 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. I have said it before, and I will say it again, containers are just fancy Linux processes. 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. Porting is the task of doing any work necessary to make the computer program run in the new environment. configuration testing is also known as H/W compatability. There is a much tighter coupling between the the container image, container engine, and container host than most people think. This enables application developers to reduce software development costs and bring products to market quickly, and enables users to upgrade hardware while retaining their software applications and minimizing conversion costs. 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. "Name": "mcr.microsoft.com/windows/nanoserver". Portability - you can move the image where you want. The origins of contemporary reliability engineering can be traced to World War II. Compatibility - they are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). // Intel is committed to respecting human rights and avoiding complicity in human rights abuses. This is what vendors can support. Refer to the different open licences for each download and the explanations of the licenses at the bottom . i) Identify the most appropriate type of test that he could test. the second one can be directly run on any platform. Intel C++ Compiler Classic Developer Guide and Reference. Ukraine ARM binaries in a container image will not run on POWER container hosts - Windows Nano binaries in a container image will not run on a RHEL 8 container host. It means that to really achieve portability, and hence agility in your business, you need to plan. McCarty is a social media start-up veteran, an e-commerce old timer, and a weathered government research technologist, with experience across a variety of companies and organizations, from seven person startups to 20,000employee technology companies. Versions Compatibility Requirements Common Portability kinds are applicatiion, source code and data portability. If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Supportability: It helps in maintaining the testability, extendibility and correctability. Software is developed or engineered; it is not manufactured in the classical sense. Charlie intends to validate an information system by tracing the system code: Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. Outline two responsibilities of a system analyst in an organization 2. Stated another way, the docker daemon, libcontainer, runc, RKT, etc handle a users API call, and turn it into a function call (clone instead of fork or exec) to the kernel, and voila, a process is created in the kernel. It would seem, that even Docker agrees, as they developed the Moby project and LinuxKit to be able to tightly couple these three things (host, engine, image) in what amounts to essentially a Unikernel like structure. 11 Geroev avenue, apt 49 In practice the claim of languages, like C and C++, to have the WOCA (write once, compile anywhere) is arguable. This is about investing in testing, security, performance, architecture, a support team, testing that images and binaries are built in a way that they run correctly on a given set of container hosts as well as updating the code should security, performance or bugs crop up. How its possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? 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. b)Management of a records in a firm: Software which is not portable in this sense will have to be transferred with modifications to support the environment on the destination machine. No matter how hard you try, ARM binaries in a container image will not run on POWER container hosts. If you are a RHEL 7.3 shop, do the same thing. Software design and prototyping 4. Lets analyze a few key log messages to see why. Portability - you can move the image where you want. All rights reserved. It can be a calculation, data manipulation, business process, user interaction, or any other specific functionality which defines what function a system is likely to perform. Research statistics indicates high rate of system project failures. Even if we added an /etc/passwd file, the binaries would fail to run because they are Windows binaries, not Linux ELF binaries. // See our complete legal Notices and Disclaimers. It makes applications or software run more efficiently and illustrates the system's quality. The concept of software portability has different meanings to different people. 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. Save yourself the pain, if you are an Ubuntu 16 shop, run the docker engine that comes with Ubuntu 16, and run Ubuntu 16 container images. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). Consistent packaging mechanics, like VM . 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. While achieving portability is key for a wide range of software types, it is particularly important in Web application development. I will be understanding something this article.s, Your email address will not be published. Part I Transition Information for Users and System Administrators, Advantages of Migrating to the Solaris Operating Environment, 2010, Oracle Corporation and/or its affiliates. Differentiate between portability and compatibility qualities as used in system design, Primary Secondary College and University (PSCU) Studies, Outline two responsibilities of a system analyst in an organization, Differentiate between structured and unstructured interviews, State two desirable characteristic of internal documentation of a program, With the aid of a diagram, describe a closed control system, Transaction processing system play a vital role in organization. The above graphic shows all of the moving parts in a typical Kubernetes environment. Portability A set of attributes that bear on the ability of software to be transferred from one environment to another. So, the distinction or difference between these two started to blur and portability meets interoperability. (d)Manipulation of numeric data collected from a research station. USB ports are becoming quite common with modern devices. Software can be custom built or custom build. We are happy you want to contribute to DXKB. (ii) Explain two problems that she could experience while using the fact-finding method identified in (i). ii) Outline four advantages of the changeover strategy identified. Differentiate between volatile and non-volatile memory. Tons of technical people are out there showing demos of interoperability that doesnt explain the whole story, and in fact leads people down a really bad path. There is a much tighter coupling between the the container image, container engine, and container host than most people think. For example, Google Chrome is compatible with Windows 10. Download our open textbooks in different formats to use them in the way that suits you. testing. There are two types of cross-platform software: Cross-platform applications can run e.g. It is verifying your software application to be compatible with different versions of the software. State the role of the following utility software in a computer system. Such web applications must, for security reasons, have limited control over the host computer, especially regarding reading and writing files. First, the work of organizing and creating a container is done in user space. Heres why: Whats new in Red Hat Enterprise Linux 9 Beta. Collectively, they affect both the utility and the life-cycle costs of a product or system. The Program Compatibility Assistant detects compatibility issues and allows you to reinstall using the recommended settings. There is not even acontainer object in the Linux kernel, there never has been. It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. For instance checking your Microsoft Word to be compatible with Windows 7, Windows 7 SP1, Windows 7 SP2, Windows 7 SP3. (a)Production of report for a company: Give two reasons for this. Last Updated: 04/11/2022. The biggest and most noticeable difference is the Desktop needs basic external devices to be fully functional, whereas the Laptop has all necessary devices built-in, making it the most portable. 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. Hardware is a physical part of the computer that causes the processing of data. i) Describe the type of maintenance that you would recommend for the information system. Supportability - Red Hat can fix problems in the Container Image, Container Host, Container Engine, and the Linux kernel to make sure that these components work together over a defined life cycle. Who fixes the kernel, container engine, or container image bugs and tests for regressions? A nonfunctional requirement is an attribute that dictates how a system operates. You don't want to have different behaviours on some platforms, you don't want to waste time adressing enviroment related configs. Portability we can move the image anywhere we want. Describe two key components of a term_of_refference document in information system projects. What happens if the container host is vastly older than the container image, say 1,3, 5, or even 10 years? on customer expected platforms or not. Compatibility they are designed and engineered to work together (See:. Portability defines the ability to physically move software or . Reason: Devices Compatibility Requirements are Non- functional requirements. Thomas B. London and John F. Reiser (1978). 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. 1. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image ). 3. 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. 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. supports H/W technology devices or not. Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). 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] . Difference between Portability and Compatibility Testing Objectives Attributes #1) Installability: #2) Adaptability: #3) Replaceability: #4) Compatibility or Coexistence: Portability Testing Checklist Pros and Cons Pros: Cons: Examples of Portability Testing Conclusion Recommended Reading Difference between Portability and Compatibility Testing Again, it can be difficult to deal with this and similar questions. SCORM cannot track mobile learning. - Adaptability - Installability - Coexistence - Replaceability - Portability Compliance Containers don't offer the ability to run cross-platform binaries, you'd need to use virtualization or emulation for that (example: QEMU System Emulator Targets). I think Dan Woods is right, there is a coming reliability crisis. 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. Over time, applications become more widely used and require more powerful systems to support them. Development. Compatibility is based on hardware architecture (x86 versus ARM), operating system (Linux versus Windows), Linux distribution (RHEL versus other distro), 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. What happens if your container does more than just file open(), say it needs access to dedicated hardware?
