Originally posted at: http://crunchtools.com/deeply-understanding-the-different-between-portability-compatibility-and-supportability/, You are master of this field. Distinguish between a centronic and an RS-232 port. Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). configuration testing means testing team verifies build. 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. Software is a program or set of instructions which are to be executed by CPU to do the intended task. 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. List three precautions to take when handling a diskette. Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). I think Dan Woods is right, there is a coming reliability crisis. i) Identify the changeover strategy that she could use. ii) Outline four advantages of the changeover strategy identified. c)Production of calendars and brochures: 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. Standard 4: Tin Can API. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Judes intends to select a file organization method for an information system that he was designing for a client. Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. 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. 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. In practice the claim of languages, like C and C++, to have the WOCA (write once, compile anywhere) is arguable. 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. No matter how hard you try, ARM binaries in a container image will not run on POWER container hosts. The above graphic shows all of the moving parts in a typical Kubernetes environment. They dont understand the Unix design principles. Compare a hard disk and a floppy disk in terms of storage capacity, cost, accessibility to data and data security. Software portability is the possibility to use the same software in different environments. As workloads expand beyond simple web servers which really only need to use system calls to open files and open TCP sockets, we will see more and more problems. Non Functional Requirements - Characteristics of Software. On top of this, magnify this problem over time, as all of these components age (not so gracefully). As long as I run the docker daemon on all of my hosts, everything will just work right? or syscalls that trigger special hardware? For Dev teams, Portable software can be easily used on other platforms. This compatibility problem extends to processor architecture, and also versions of the operating system. It is to determine whether your software application or product is proficient enough to run in different browsers, databases, hardware, operating system, mobile devices, and networks. What do these symbols represent in a computer system? They do the following at least: Provide an API prepare data and metadata for runc. The aim of this Guide is to provide a clear definition of interoperability and of portability and how these relate to various aspects of cloud computing and to cloud services. This is usually a task for the program developers; typical users have neither access to the source code nor the required skills. It can be very difficult to determine the cost vs. benefits ratio. Distinguish between general purpose software and in-house developed software. In a totally portable application, all related files would be stored in a single folder so it can be copied with one command. This also allows you to share infrastructure like Registry Servers. Answer (1 of 2): Software compatibility is what that operating system or program will run on. 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. Dnipropetrovsk, Heterogenous computing environments are a reality today. This software vendor evaluation guide will help your business navigate the software selection labyrinth. The Program Compatibility Assistant detects compatibility issues and allows you to reinstall using the recommended settings. 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. To demonstrate the limits, let's try and execute this Windows Nano container image on a RHEL 8 container host: The first thing youll notice is that the image fails to run. 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). Describe knowledge based system 4. Over time, applications become more widely used and require more powerful systems to support them. When the team visualizes the project details during the discovery (inception) phase, they may identify errors in the initial stage of development. Horizontal stands for platform/dependency flexibility. Reliability, maintainability, and availability (RAM) are three system attributes that are of great interest to systems engineers, logisticians, and users. Mobile compatibility comes in two forms: a stand-alone mobile app and mobile-browser accessibility. - Adaptability - Installability - Coexistence - Replaceability - Portability Compliance Requirements that focus on the compatibility of our website with different browsers like Google Chrome, Internet Explorer, Firefox, Safari, etc. Software design and prototyping 4. Portability - we can move the image anywhere we want. With numerous kinds of processors with various design philosophies available at our disposal for . Supportability: It helps in maintaining the testability, extendibility and correctability. configuration testing is also known as H/W compatability. Here is a quick set of recommendations to help ensure success: 1. the second one can be directly run on any platform. Give an example in each case. True/False, Browser Compatibility Requirements are functional requirements? 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. 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. Why is it necessary to consider user needs when purchasing new software? It would seem, that even Docker agrees, as they developed the Moby project andLinuxKit to be able to tightly couple these three things (host, engine, image) in what amounts to essentially a Unikernel like structure. It's especially useful for customers that want to move to .NET but plan to stay on Windows, at least as a first step. 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. For example, Google Chrome is compatible with Windows 10. This is foundational to the vision of hybrid and multi cloud. Lets analyze a few key log messages to see why. State two factors to be considered when buying a RAM module. There are two types of cross-platform software: Cross-platform applications can run e.g. 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 are a Fedora Server 25 shop, run the container engine that comes with Fedora Server 25, and run Fedora Server 25 images. 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. A computer program is said to be portable if there is very low effort required to make it run on different platforms. 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. Portability - you can move the image where you want. Usability: It ensures the comprehensibility, communicativeness and ease of learning. One . As mentioned before, this is to be expected because container images are platform neutral (theyre just tar files) and governed by open standards, so Linux can uncompress it and mount it: The ContainerUser is a Windows user which Podman doesn't find in a passwd file in the image. Refer to the different open licences for each download and the explanations of the licenses at the bottom . Porting is no more than transferring specified directories and their contents. State the role of the following utility software in a computer system. supports H/W technology devices or not. High-quality requirements and wireframes help to predict the result and develop the project that meets your expectations. Software can be custom built or custom build. 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). What happens if the docker daemon triggers a kernel bug when it is trying to create a container on a version of a kernel for which it was not tested or certified to work with? Focus areas include cloud, containers, workload expansion, and automation. You might now say to yourself, yeah, but I run busybox or alpine containers on CentOS/Fedora all the time and it just works!!! And other updates in Red Hat Runtimes, Infusing your UX writing with brand personality. Kubernetes is the future: But what does this future look like? Hardware is a set of physical parts of computers which actually executes the instruction. Outline two responsibilities of a system analyst in an organization 2. Because Android is an open source project, any hardware manufacturer can build a device that runs the Android operating system. Transferring installed program files to another computer of basically the same architecture. Charlie intends to validate an information system by tracing the system code: It makes applications or software run more efficiently and illustrates the system's quality. Reason: Operating Systems Compatibility Requirements are functional requirements. Development. Portability you can move the image where you want. Their goals, approaches, and guidelines overlap significantly. Required fields are marked *. What is Non functional software Testing? Imagine tunning your enviroments every single staging, no dev-ops team wants to deal with unnecessary work just because code is not flexible. What is Software Compatibility Testing?
