This is foundational to the vision of hybrid and multi cloud. So, the distinction or difference between these two started to blur and portability meets interoperability. Distinguish between a centronic and an RS-232 port. 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. A computer game that must work on Windows 7, Windows 8, and Windows 10. Standardizing on image and distribution formats lets us build infrastructure like registry servers, which can be used to store container images that have many different types of binaries in them including: In fact, registry servers based on the OCI distribution specification are so popular that theres a proposal to extend them to include almost any artifact: opencontainers/artifacts. First, the work of organizing and creating a container is done in user space. Software is a set of instructions that tells a computer exactly what to do. The origins of contemporary reliability engineering can be traced to World War II. i) Identify the most appropriate type of test that he could test. However, as long as the operating systems are reasonably similar, the binaries in the container image will usually run. 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. 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 has culminated in a unique perspective on open source software development, delivery, and maintenance. Even if we added an /etc/passwd file, the binaries would fail to run because they are Windows binaries, not Linux ELF binaries. Testing 6. Horizontal stands for platform/dependency flexibility. Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). To explain the terms then two basic entities are required: Components are one of the parts that make up a system, while a system is a collection of components organised to accomplish a specific function or a set of functions (both from IEEE 610). Supportability is about putting a reasonable scope around what is and isnt covered by a Red Hat subscription. Describe three advantages of the tool that could be influencing this trend. The Program Compatibility Assistant detects compatibility issues and allows you to reinstall using the recommended settings. 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. Lets analyze a few key log messages to see why. (i) Explain the most appropriate data gathering technique that she could use For instance checking your Microsoft Word to be compatible with Windows 7, Windows 7 SP1, Windows 7 SP2, Windows 7 SP3. (ii) Explain two problems that she could experience while using the fact-finding method identified in (i). Deep means how scalable and replicable your code/architecture/software is. 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. i) Identify the changeover strategy that she could use. // No product or component can be absolutely secure. Who fixes the kernel, container engine, or container image bugs and tests for regressions? C, The first thing youll notice is that the image fails to run. (d)Manipulation of numeric data collected from a research station. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). Also, high quality support is based on a well defined and scoped set of components that are designed and engineered to work together. It makes applications or software run more efficiently and illustrates the system's quality. All rights reserved. Also, high-quality support is based on a well defined and scoped set of components that are designed and engineered to work together. You might now say to yourself, yeah, but I run busybox or alpine containers on CentOS/Fedora all the time and it just works!!! : utime() fails under Windows with EACCES, when it is called for a directory). Accessibility, Usability, and Inclusion. The examiner could want to establish whether you can differentiate between hardware and software portability; Another major development in this question is the word portability. 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. Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. 3. We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. Differentiate between portability and compatibility qualities as used in system design Viewed: 310 times Share in: Question Answer: Questions List: 1. 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. The Solaris operating environment is portable, scalable, interoperable, and compatible. As of 2011[update] the majority of desktop and laptop computers used microprocessors compatible with the 32- and 64-bit x86 instruction sets. Software portability is a key concern when configuration settings affect software correctness and target operational environments are highly configurable. 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. In this video, i am going to describe the Difference Between MOBILITY and PORTABILITY mobile computing? 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 . Standard operating environment . 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] . Compatibility requirements about the ease of moving components or systems between environments (Environments can be hardware and/or software environment). Common Portability kinds are applicatiion, source code and data portability. Containers do not offer compatibility guarantees; only virtualization can do that. - CertDepot, 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. What is Software Compatibility Testing? You don't want to have different behaviours on some platforms, you don't want to waste time adressing enviroment related configs. Many to-many Relationship, Most software developers are adopting object oriented analysis and design. For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 If you are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. Portable data can be moved from one database or repository to another. Reason: Versions Compatibility Requirements are non-functional requirements. When writing 32-bit code, you can use the 64-bit version of Office without any changes. First, notice that Podman is able to mount the container image. Replication (deep) The first dimension of portability is crucial to operating cloud applications at scale - scaling and replication. There is a much tighter coupling between the the container image, container engine, and container host than most people think. One . d)Video graphic adaptor: Give two differences between a DVD and VCD. Consistent packaging mechanics, like VM . Hardware Compatibility Requirements are functional requirements? Software is developed or engineered; it is not manufactured in the classical sense. 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. (a)Production of report for a company: Outline two responsibilities of a system analyst in an organization 2. Nor can Red Hat go patch and update every Linux container image thats out there. 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. 5G core adoption the open way with Red Hat OpenShift, Whats new with Quarkus? a)Polychromatic screen: Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. Please choose your preferred way, Issues in the Specification and Measurement of Software Portability. Their goals, approaches, and guidelines overlap significantly. For example we got this error trying to install a music interface device driver for home recording. Use of compatible software ensures that various kinds of files such as word processing documents, spreadsheets, data files and email can be shared between staff in various locations without any concerns about data conversion or inability to read others' files. Smaller portable devices use processors with different and incompatible instruction sets, such as ARM. What happens if the glibc in your application, inside the container doesnt use hardware accelerated routines because the underlying kernel didnt enable it? +38 093 252 99 56 To operate in a growing environment, software must be able to run in a wide power range and must be able to take advantage of the additional processing power. 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. Others may feel that a significant amount of restructuring at the source level is still consistent with portability. What is Non functional software Testing? Compare a hard disk and a floppy disk in terms of storage capacity, cost, accessibility to data and data security. For Sales teams, the main reason for porting is to reach wider audience. As languages evolved and vendor lock-ins reduced, it has since morphed to mean several things including binary compatibility and source-code compatibility. This means you can share infrastructure like registry servers between cloud providers or on premise. This is usually a task for the program developers; typical users have neither access to the source code nor the required skills. In fact, registry servers based on the OCI distribution specification are so popular that theres a proposal to extend them to include almost any artifact: 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. MCQ 1: What are the characteristics of software? Most Learning Management Systems are SCORM compliant. [emailprotected]. It implies that the data are in electronic files that are readily accessible rather than only visually on a screen. So, what does all of this mean? Development Reference Guides. Operating Systems Compatibility Requirements are functional requirements? Software Portability RequirementsPortability requirements are non-functional requirements and focus on the ability of two or more components or systems to perform their required functions while all of these are in the same environment. 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. Even if we added an /etc/passwd file, the binaries would fail to run because they are Windows binaries, not Linux ELF binaries. This software is implemented on multiple platforms. Computing technology continues to advance rapidly, but the need to remain competitive requires vendors to minimize their costs and to maximize their investments. This also allows you to share infrastructure like Registry Servers. What happens when your container image expects to find a file in /proc, or /dev? Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. How many diagrams are drawn for a system in Final year project? 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 a program can run in a common web browser. 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. With good Dependency management, single sourcing and good platform support plan, you can master the Horizontal dimension. The way the word may be used with hardware, cannot not be the same way it may be used with software. This also allows you to share infrastructure like Registry Servers. Differentiate between structured and unstructured interviews 3. Software can be custom built or custom build. Collectively, they affect both the utility and the life-cycle costs of a product or system. to ISO/IEC spec]. It is most effective to address them together when designing and developing websites and applications. the second one can be directly run on any platform. System software Application software Software which is not portable in this sense will have to be transferred with modifications to support the environment on the destination machine. 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. True/False. 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. 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. This is a compatibility problem, even though the image is portable. Otherwise, the data must be retyped word for word into another application and on-screen images must be captured one at a time. As long as I run the docker daemon on all of my hosts, everything will just work right? The Windows Compatibility Pack sits on top of .NET Standard and provides access to these Windows-only technologies. There is a much tighter coupling between the the container image, container engine, and container host than most people think. compatability testing means testing team verifies build run. Software design and prototyping 4. testing. configuration testing means testing team verifies build. For example, Google Chrome is compatible with Windows 10. This means you can share infrastructure like registry servers between cloud providers or on-premise. Requirements that software must be compatible with different Operating Systems like Windows, Unix, Mac OS, etc. The image format is the same no matter which operating system or binaries are in the container image. True/False. Intel technologies may require enabled hardware, software or service activation. True/False. 2. 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. 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. The aim of this note is to provide an explanation of the four terms as used by the Testing Standards Working Party. Good news is that as network speeds approach computer bus speeds, the network becomes the computer, Portability starts embracing Interoperability issues and Interoperability can start gleaning the benefits of Portability. There is not even acontainer object in the Linux kernel, there never has been. the first one requires individual building or compilation for each platform. One-to-one Relationship However, as long as the operating systems are reasonably similar, the binaries in the container image will usually run. This software vendor evaluation guide will help your business navigate the software selection labyrinth. 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 . Your email address will not be published. Containers do not offer compatibility guarantees; only virtualization can do that. configuration testing is also known as H/W compatability. Mobile compatibility comes in two forms: a stand-alone mobile app and mobile-browser accessibility. Better than just free, these books are also openly-licensed! Horizontal stands for platform/dependency flexibility. 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. Outline four factors that he should consider in the selection, other than cost. Required fields are marked *. If you would like to see another example of compatibility problems, even between very similar Linux distros, see The limits of compatibility and supportability with containers. (yes, this can happen). This compatibility problem extends to processor architecture, and also versions of the operating system. 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. -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. In that scenario, you can use Windows-only technologies removes the migration hurdle. Portability - you can move the image where you want. c)Antivirus. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). Your email address will not be published. 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) "Digest": "sha256:65d0f8a710e5add87e539b6eb25c724d73fba7c090735133246ff7c5ae1100a5", "sha256:c40da4de5e84fba9e2c0f302d2d30570160680b4a2d4ae5a558796337e2dfca2", mcr.microsoft.com/windows/nanoserver 1903 8b8ec38e0f40 7 days ago 263 MB, This is what determines if the binaries in the container image can actually run on the container host. Or difference between these two started to blur and portability meets interoperability portability kinds are applicatiion source.
