True/False, Network Compatibility Requirements are Non-functional requirements? The Solaris operating environment runs on machines of all sizes, from laptops to supercomputers. While achieving portability is key for a wide range of software types, it is particularly important in Web application development. The 64-bit versions of Office enable you to move more data around for increased capability, for example when you work with large numbers in Microsoft Excel 2010. The Solaris operating environment is portable, scalable, interoperable, and compatible. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Differentiate between USB and SCSI ports. Second, there is no layer of abstraction, like virtualization. Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. True/False, Browser Compatibility Requirements are functional requirements? Click on each book cover to see the available files to download, in English and Afrikaans. // No product or component can be absolutely secure. Porting is no more than transferring specified directories and their contents. Yet, a device is "Android compatible" only if it can correctly run apps written for the Android execution environment. Then, it can divide itself into several independent "virtual machines." 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. Differentiate between portability with reference to hardware and software. Kubernetes is the future: But what does this future look like? Planning 2. Here the brevity of the lines of code is important. d)Video graphic adaptor: Give two differences between a DVD and VCD. i) Identify the most appropriate type of test that he could test. Thomas B. London and John F. Reiser (1978). Your Red Hat account gives you access to your member profile, preferences, and other services depending on your customer status. Hardware is manufactured in factories. 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. If you're truly gung-ho on interface . Such a program can run in a common web browser. Define the following terms as used with monitor technology in computing. Many to-many Relationship, Most software developers are adopting object oriented analysis and design. In Hindi in the simple and easy way. -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. The image format is the same no matter which operating system or binaries are in the container image. 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. Name any three hardware details that should be considered before installing any software. A thorough examination of the differences between products will ensure you're getting exactly what you needno more, no less. (i) Explain the most appropriate data gathering technique that she could use compatability testing is also known as protability testing. Required fields are marked *. Because Android is an open source project, any hardware manufacturer can build a device that runs the Android operating system. Portability you can move the image where you want. Supportability: It helps in maintaining the testability, extendibility and correctability. They also want too avoid lock-ins (on certain libraries or dependencies). Red Hat cannot guarantee that every permutation of Linux container image and host combination on the planet will run on RHEL container hosts. Answer / sampathi kotla. There is not even acontainer object in the Linux kernel, there never has been. You also need Compatibility and Supportability. The comparison table is a much more versatile tool than . Intel technologies may require enabled hardware, software or service activation. Porting is the task of doing any work necessary to make the computer program run in the new environment. If you are a RHEL 7.3 shop, do the same thing. This means you can share infrastructure like registry servers between cloud providers or on premise. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. Collectively, they affect both the utility and the life-cycle costs of a product or system. Differentiate between portability with reference to hardware and software. 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). True/False, Versions Compatibility Requirements are functional requirements? i) Describe the type of maintenance that you would recommend for the information system. In practice the claim of languages, like C and C++, to have the WOCA (write once, compile anywhere) is arguable. ! 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? Compatibility they are designed and engineered to work together (See:. We are happy you want to contribute to DXKB. For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 However, as long as the operating systems are reasonably similar, the binaries in the container image will usually run. or syscalls that trigger special hardware? All rights reserved. b)Compressor If you are setting up a large, distributed systems environment with container orchestration such as Kubernetes, across 100s if not 1000s of hosts, there are already a lot of moving parts why give yourself another headache to worry about? This addresses the content inside the container image. As to whether there is a certain intersection between portability and compatibility between various platforms, the following discussion is carried out. Compatibility - they are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). State two factors to be considered when buying a RAM module. Walled gardens prevent data from being easily transferred. At Red Hat, Scott McCarty is Senior Principal Product Manager for RHEL Server, arguably the largest open source software business in the world. Operating Systems Compatibility Requirements are functional requirements? Dnipropetrovsk, Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. 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. 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. Standard operating environment . Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). Another you can try is to use platform-independent language (for example, while C# is great for Windows, on Linux it is not the best option). The authors of UNIX/32V (1979) reported that "[t]he (Bourne) shell [] required by far the largest conversion effort of any supposedly portable program, for the simple reason that it is not portable."[1]. This means you can share infrastructure like registry servers between cloud providers or on-premise. Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. 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. How many 1.44MB diskettes would be used to store data that require storage space of 4.7 GB. Differentiate is the major keyword in this question. Such questions are not always easy to answer. SCORM can track learning that happens only on laptops or desktops. Intel C++ Compiler Classic Developer Guide and Reference. 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. 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. Portability is "the ability of software or data to be transferred from one machine or system to another" [5] . Well, it means two very important things. Checking your software is compatible with mobile platforms like Android, iOS, etc. 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. 1. Requirements that software must have a good performance in a network with parameters such as Operating speed, Bandwidth, and Capacity, etc. Part I Transition Information for Users and System Administrators, Advantages of Migrating to the Solaris Operating Environment, 2010, Oracle Corporation and/or its affiliates. What is Software Compatibility Testing? Who fixes the kernel, container engine, or container image bugs and tests for regressions? Outline four factors that he should consider in the selection, other than cost. Portability we can move the image anywhere we want. So, it is possible that the costs exceed the benefits. 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. Distinguish between general purpose software and in-house developed software. What happens if your container does more than just file open(), say it needs access to dedicated hardware? I am here to break it to you its not magic. 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 . For example, Google Chrome is compatible with Windows 10. It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. Have you ever wondered, how are containers are so portable? Compare a hard disk and a floppy disk in terms of storage capacity, cost, accessibility to data and data security. The Solaris operating environment is portable, scalable, interoperable, and compatible. It makes applications or software run more efficiently and illustrates the system's quality. Learn how to get started with our official documentation. It applies to the software that is available for two or more different platforms or can be recompiled for them. Compatibility is non-functional testing to ensure customer satisfaction. Software is a program or set of instructions which are to be executed by CPU to do the intended task. Portability The SunOS 5.7 product is portable across multiple vendor platforms. . Portability - you can move the image where you want. 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. How many diagrams are drawn for a system in Final year project? As long as I run the docker daemon on all of my hosts, everything will just work right? Your email address will not be published. So, if your dev team moves to different enviroment, you don't want to waste time and resources on re-development. the second one can be directly run on any platform. Its fun to experiment and see what will work, but dont deploy production applications this way. 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. Software conforming to an application binary interface (ABI) runs as shrink-wrapped software on all vendor systems with the same microprocessor architecture. As new technology is introduced, there is a need for the existing software investment to be preserved. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). This is what vendors can support. 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. We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). Manage your Red Hat certifications, view exam history, and download certification-related logos and documents. 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. 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. Standard 4: Tin Can API. (d)Manipulation of numeric data collected from a research station. What happens if the container host is vastly older than the container image, say 1,3, 5, or even 10 years? This is a compatibility problem, even though the image is portable. Implementation defined things like byte order and the size of an int can also raise the porting effort. Dependency. Reinstalling a program from distribution files on another computer of basically the same architecture. The way the word may be used with hardware, cannot not be the same way it may be used with software. 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. This addresses the content inside the container image. 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. Better than just free, these books are also openly-licensed! A function is nothing but inputs to the software system, its behavior, and outputs. 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). When writing 32-bit code, you can use the 64-bit version of Office without any changes. 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. Describe knowledge based system 4. 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. Should the existing program be ported, or should an equivalent program be redeveloped? Which software would you use for the following? What happens if your container expects a certain kernel module to be loaded and running? Mobile Compatibility Requirements Checking your software is compatible with mobile platforms like Android, iOS, etc. But comparison tables are equally well-suited to services, membership levels, pricing packages, software features, tuition rates, or locations. Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. This is what vendors can support.
