distinguish between portability and compatibility as used in software selection

As of 2011[update] the majority of desktop and laptop computers used microprocessors compatible with the 32- and 64-bit x86 instruction sets. Portable applications can be converted from one computer environment to another one. Dont mix and match distributions and version its crazy talk. The comparison table is a much more versatile tool than . Software installed on portable mass storage devices such as USB sticks can be used on any compatible computer on simply plugging the storage device in, and stores all configuration information on the removable device. Who fixes the kernel, container engine, or container image bugs and tests for regressions? But comparison tables are equally well-suited to services, membership levels, pricing packages, software features, tuition rates, or locations. For instance checking your Microsoft Word to be compatible with Windows 7, Windows 7 SP1, Windows 7 SP2, Windows 7 SP3. (d)Manipulation of numeric data collected from a research station. 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. For Sales teams, the main reason for porting is to reach wider audience. 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 . True/False. So, what does all of this mean? Outline two responsibilities of a system analyst in an organization 2. 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. List three precautions to take when handling a diskette. The way the word may be used with hardware, cannot not be the same way it may be used with software. I am here to break it to you its not magic. 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. How many 1.44MB diskettes would be used to store data that require storage space of 4.7 GB. Portability - we can move the image anywhere we want. More users mean increased profit. 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. Give three items that should come along with an authentic software. First, notice that Podman is able to mount the container image. 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. Checking your software is compatible with mobile platforms like Android, iOS, etc. To some, software is portable only if the executable files can be run on a new platform without change. No matter how hard you try, ARM binaries in a container image will not run on POWER container hosts. This is what determines if the binaries in the container image can actually run on the container host. I have said it before, and I will say it again, containers are just fancy Linux processes. Hardware- and software-specific information is often stored in configuration files in specified locations (e.g. 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. What degree of portability is desired for the various environments? When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. This means you can share infrastructure like registry servers between cloud providers or on premise. b)Compressor Define the following terms as used with monitor technology in computing. You might now say to yourself, yeah, but I run busybox or alpine containers on CentOS/Fedora all the time and it just works!!! Software is developed or engineered; it is not manufactured in the classical sense. Distinguish between general purpose software and in-house developed software. Porting is the task of doing any work necessary to make the computer program run in the new environment. Walled gardens prevent data from being easily transferred. Even if we added an /etc/passwd file, the binaries would fail to run because they are Windows binaries, not Linux ELF binaries. Well, it means two very important things. However, as long as the operating systems are reasonably similar, the binaries in the container image will usually run. Reason: Operating Systems Compatibility Requirements are functional requirements. Compatibility is non-functional testing to ensure customer satisfaction. It is verifying your software application to be compatible with different versions of the software. reuse concepts on average, only about 15% of any software product serves anoriginal purpose the other 85% in theory can be standardized and reused infuture products reuse rates theoretical upper limit of 85% reuse rates of 40% can be achieved in practice a product is portable if it is significantly easier to modify itto run on another For personal projects, the selection of a programming language may be as simple as picking a personal favorite. Ukraine It makes applications or software run more efficiently and illustrates the system's quality. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). 1. Some functions can be available on a target system, but exhibit slightly different behaviour (E.g. 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. 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 answer is.no. The original meaning of 'portable' was 'costs less to convert to a new platform than it does to rewrite for the new platform'. Red Hat cannot guarantee that every permutation of Linux Container Image and host combination on the planet will work. There are two types of cross-platform software: Cross-platform applications can run e.g. 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. [emailprotected]. Portability alone does not offer the entire promise of Linux containers. Your email address will not be published. All rights reserved. Red Hat cannot guarantee that every permutation of Linux Container Image and host combination on the planet will work. Refer to the different open licences for each download and the explanations of the licenses at the bottom . One-to many/ Many to-one Relationship Hardware is a set of physical parts of computers which actually executes the instruction. Nor can Red Hat go patch and update every Linux container image thats out there. Software doesn't "wear out". 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) Portability A set of attributes that bear on the ability of software to be transferred from one environment to another. Program Compatibility is a mode that allows you to run programs that were written for earlier versions of Windows. Differentiate between open source and proprietary software. They can be used to compare similar items from the same organization, or to compare one organization's products against those of a competitor. Required fields are marked *. Software can be compiled and linked from source code for different operating systems and processors if written in a programming language supporting compilation for the platforms. 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. 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. It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. Most Learning Management Systems are SCORM compliant. It applies to the software that is available for two or more different platforms or can be recompiled for them. Heres why: The standardized format of containers is what makes them portable between registry servers and container hosts. For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 Distinguish between a centronic and an RS-232 port. Your email address will not be published. There are two types of compatibility: device compatibility and app compatibility . You don't want to have different behaviours on some platforms, you don't want to waste time adressing enviroment related configs. 5G core adoption the open way with Red Hat OpenShift, Whats new with Quarkus? 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. This page was last edited on 12 December 2022, at 23:50. Containers do not offer compatibility guarantees; only virtualization can do that. 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. A function is nothing but inputs to the software system, its behavior, and outputs. Reason: Devices Compatibility Requirements are Non- functional requirements. Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Key steps in software development process 1. It is manufactured. Yet, a device is "Android compatible" only if it can correctly run apps written for the Android execution environment. 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. With the aid of a diagram, describe two symbols used in use case diagram. Software is a program or set of instructions which are to be executed by CPU to do the intended task. Assume you are hired as system analyst, c)Refresh rate: What is Non functional software Testing? // No product or component can be absolutely secure. Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). ! 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? Maintenance What factors affect the time it takes to the software development process? What happens if the container image is vastly older than the container host, say 1, 3, 5, or even 10 years? Containers do not offer compatibility guarantees; only virtualization can do that. CRITERIA FOR SELECTING A COMPUTER SYSTEM A good computer system is one that meets all 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. The pre-requirement for portability is the generalized abstraction between the application logic and system interfaces. On top of this, magnify this problem over time, as all of these components age (not so gracefully). Here is a quick set of recommendations to help ensure success: 1. True/False. Software is a set of instructions that tells a computer exactly what to do. Mobile Compatibility Requirements Checking your software is compatible with mobile platforms like Android, iOS, etc. You want to deploy your application as a containerized application using containers such as docker. This means the document may have a different format or use a . The ContainerUser is a Windows user which Podman doesnt find in a passwd file in the image. 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. Public Content. Testing 6. As long as I run the docker daemon on all of my hosts, everything will just work right? Differentiate between portability with reference to hardware and software. - Adaptability - Installability - Coexistence - Replaceability - Portability Compliance Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work.
