Charlie intends to validate an information system by tracing the system code: What happens if the container image is vastly older than the container host, say 1, 3, 5, or even 10 years? Devices Compatibility Requirements are functional requirements? Differentiate between open source and proprietary software. The original meaning of 'portable' was 'costs less to convert to a new platform than it does to rewrite for the new platform'. The image format is the same no matter which operating system or binaries are in the container image. Usability: It ensures the comprehensibility, communicativeness and ease of learning. How many diagrams are drawn for a system in Final year project? Transferring installed program files to another computer of basically the same architecture. Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. Define the following terms as used with monitor technology in computing. True/False. // Intel is committed to respecting human rights and avoiding complicity in human rights abuses. Your email address will not be published. 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/. Requirements that software must have a good performance in a network with parameters such as Operating speed, Bandwidth, and Capacity, etc. Portability is "the ability of software or data to be transferred from one machine or system to another" [5] . The concept of software portability has different meanings to different people. 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're truly gung-ho on interface . Sometimes the effort consists of recompiling the source code, but sometimes it is necessary to rewrite major parts of the 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. Judes intends to select a file organization method for an information system that he was designing for a client. Expanding the scope of container images which are supported, increases the testing, analysis, and repair matrix at a non-linear growth rate. What happens if the glibc in your application, inside the container doesnt use hardware accelerated routines because the underlying kernel didnt enable it? Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). State two advantages of general purpose software. State the role of the following utility software in a computer system. Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. Many to-many Relationship, Most software developers are adopting object oriented analysis and design. Accessibility, usability, and inclusion are closely related aspects in creating a web that works for everyone. This means you can share infrastructure like registry servers between cloud providers or on-premise. Browse Knowledgebase articles, manage support cases and subscriptions, download updates, and more from one place. Required fields are marked *. (i) Explain the most appropriate data gathering technique that she could use You also need Compatibility and Supportability. Thomas B. London and John F. Reiser (1978). Deployment 7. Manage your Red Hat certifications, view exam history, and download certification-related logos and documents. 1. 1. The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. 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. Differentiate between portability with reference to hardware and software. State two precautions that should be observed when installing a new piece of hardware into a computer system. Transferring installed program files to another computer of basically the same architecture. If you are a RHEL 7.3 shop, do the same thing. True/False, Versions Compatibility Requirements are functional requirements? Even if we added an /etc/passwd file, the binaries would fail to run because they are Windows binaries, not Linux ELF binaries. With numerous kinds of processors with various design philosophies available at our disposal for . c)Refresh rate: the second one can be directly run on any platform. or syscalls that trigger special hardware? This addresses the content inside the container image. The Solaris operating environment is portable, scalable, interoperable, and compatible. Explain three features associated with this methodology, Define the term resource as used in project management. Also, high quality support is based on a well defined and scoped set of components that are designed and engineered to work together. b)Compressor i) Identify the most appropriate type of test that he could test. If you wanted to, you could even mix binaries from multiple different hardware architectures or operating systems in the same container image. As new technology is introduced, there is a need for the existing software investment to be preserved. This means you can share infrastructure like registry servers between cloud providers or on-premise. However, as long as the operating systems are reasonably similar, the binaries in the container image will usually run. The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. 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. True/False. This is foundational to the vision of hybrid and multi cloud. Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). testing. Functional Requirements in Software Engineering are also called Functional Specification. Lets dig into these three concepts a bit deeper: Since the OCI standard governs the images specification, a container image can be created with Podman, pushed to almost any container registry, shared with the world, and consumed by almost any container engine including Docker, RKT, CRI-O, containerd and, of course, other Podman instances. 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. A computer program is said to be portable if there is very low effort required to make it run on different platforms. Users purchase systems from many vendors to implement the solutions they need. Also, high-quality support is based on a well defined and scoped set of components that are designed and engineered to work together. A nonfunctional requirement is an attribute that dictates how a system operates. State four factors that should be considered when buying an input device. When writing 32-bit code, you can use the 64-bit version of Office without any changes. . the registry on machines running Microsoft Windows). Nonfunctional requirements differ from functional requirements in the following ways: Mandatory vs. non-mandatory: In contrast to functional requirements, nonfunctional . 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. c)Production of calendars and brochures: c)Antivirus. I have said it before, and I will say it again, containers are just fancy Linux processes. One . [emailprotected]. In this video, i am going to describe the Difference Between MOBILITY and PORTABILITY mobile computing? The way the word may be used with hardware, cannot not be the same way it may be used with software. Software portability is the possibility to use the same software in different environments. At Red Hat, Scott McCarty is Senior Principal Product Manager for RHEL Server, arguably the largest open source software business in the world. Supportability is based on a vendors ability to release, patch, version, and test a set of components together. With regards to Windows apps, such programs would not use the Registry. Development Reference Guides. Portability - you can move the image where you want. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Heres why: Whats new in Red Hat Enterprise Linux 9 Beta. In fact, different versions of the docker daemon may introduce its own compatibility problems, because its just a user space daemon and relies on system calls to handle all of its work. Software can be custom built or custom build. List two differences between buffer and a register. Reinstalling a program from distribution files on another computer of basically the same architecture. Hardware is a set of physical parts of computers which actually executes the instruction. This addresses the content inside the container image. 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. For example, MS Word application must be compatible with other software like MS Powerpoint, MS Excel,etc. Portability in high-level computer programming is the usability of the same software in different environments. and portability are significant considerations in relation to the use of cloud services, but there is also confusion and misunderstanding of exactly what this entails. The program code itself can also contain unportable things, like the paths of include files. 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. Give three items that should come along with an authentic software. 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. 11 Geroev avenue, apt 49 a)Merge For personal projects, the selection of a programming language may be as simple as picking a personal favorite. In practice the claim of languages, like C and C++, to have the WOCA (write once, compile anywhere) is arguable. Since the Open Containers Initiative defines the image and distribution specifications, a Container Image can be created with Podman, pushed to any container registry with Skopeo, shared with the world, and consumed by any OCI compatible container engine including Docker, RKT, CRI-O, containerd and, of course Podman or Skopeo. 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 . Outline two data capturing methods that could be used in an information system. Public Content. Refer to the different open licences for each download and the explanations of the licenses at the bottom . Describe three advantages of the tool that could be influencing this trend. In the simplest case, the file or files may simply be copied from one machine to the other. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). i) Identify the changeover strategy that she could use. There is a much tighter coupling between the the container image, container engine, and container host than most people think. © 2023 Tutorke Limited. Distinguish between a centronic and an RS-232 port. What degree of portability is desired for the various environments? Compatibility the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). 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. There is not even acontainer object in the Linux kernel, there never has been. Well, it means two very important things. Compare a hard disk and a floppy disk in terms of storage capacity, cost, accessibility to data and data security. 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. Mobile Compatibility Requirements are Non-functional requirements? 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. // See our complete legal Notices and Disclaimers. As users usually don't have access to the source code and they are not skilled enough to do it, it's a task for developers. Portability - you can move the image where you want. Answer (1 of 2): Software compatibility is what that operating system or program will run on. Mobility The pre-requirement for portability is the generalized abstraction between the application logic and system interfaces. Answer / sampathi kotla. This compatibility problem extends to processor architecture, and also versions of the operating system. On top of this, magnify this problem over time, as all of these components age (not so gracefully). 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. What happens if your container does more than just file open(), say it needs access to dedicated hardware? Accessibility, Usability, and Inclusion. Portability - we can move the image anywhere we want. For instance checking your Microsoft Word to be compatible with Windows 7, Windows 7 SP1, Windows 7 SP2, Windows 7 SP3. No matter how hard you try, ARM binaries in a container image will not run on POWER container hosts. 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. There are two types of compatibility: device compatibility and app compatibility . The origins of contemporary reliability engineering can be traced to World War II. There are two types of cross-platform software: Cross-platform applications can run e.g. Dependency. 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. Such questions are not always easy to answer. In general, programs that adhere to standard program . I am here to break it to you its not magic. Give an example in each case.
