distinguish between portability and compatibility as used in software selection
Judes intends to select a file organization method for an information system that he was designing for a client. Would you run binaries from different Linux distributions in production? In a totally portable application, all related files would be stored in a single folder so it can be copied with one command. Which software would you use for the following? 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. (i) Explain the most appropriate data gathering technique that she could use It is most effective to address them together when designing and developing websites and applications. True/False, Versions Compatibility Requirements are functional requirements? This compatibility problem extends to processor architecture, and also versions of the operating system. If you wanted to, you could even mix binaries from multiple different hardware architectures or operating systems in the same container image. Required fields are marked *. The Solaris operating environment is portable, scalable, interoperable, and compatible. It would expand the testing and analysis matrix at a non-linear growth rate. Lets analyze a few key log messages to see why. With good Dependency management, single sourcing and good platform support plan, you can master the Horizontal dimension. The Solaris operating environment is portable, scalable, interoperable, and compatible. We deliver hardened solutions that make it easier for enterprises to work across platforms and environments, from the core datacenter to the network edge. 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. Stated another way, scoping support for container images can be very expensive. Horizontal stands for platform/dependency flexibility. 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. Distinguish between a centronic and an RS-232 port. For example, Google Chrome is compatible with Windows 10. Portability - you can move the image where you want. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. Hardware- and software-specific information is often stored in configuration files in specified locations (e.g. List two differences between buffer and a register. System software Application software Explain three features associated with this methodology, Define the term resource as used in project management. 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. Better than just free, these books are also openly-licensed! Try running a RHEL 8 container image on a RHEL 4 container host that isnt going to work. True/False. So, what does all of this mean? In earlier days source code was often distributed in a standardised format, and could be built into executable code with a standard Make tool for any particular system by moderately knowledgeable users if no errors occurred during the build. . c)Refresh rate: 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. Outline four factors that he should consider in the selection, other than cost. Heres why: Whats new in Red Hat Enterprise Linux 9 Beta. This is what vendors can support. b)Management of a records in a firm: 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. Difference between Portability and Compatibility Testing Objectives Attributes #1) Installability: #2) Adaptability: #3) Replaceability: #4) Compatibility or Coexistence: Portability Testing Checklist Pros and Cons Pros: Cons: Examples of Portability Testing Conclusion Recommended Reading Difference between Portability and Compatibility Testing 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. Compare a hard disk and a floppy disk in terms of storage capacity, cost, accessibility to data and data security. Linux vs Windows is an age-old battle of the operating systems which has led to wars, disagreements and almost fanatical behavior on the Internet, for what seems like forever. In the simplest case, the file or files may simply be copied from one machine to the other. Also, high quality support is based on a well defined and scoped set of components that are designed and engineered to work together. The origins of contemporary reliability engineering can be traced to World War II. Intel technologies may require enabled hardware, software or service activation. Intel C++ Compiler Classic Developer Guide and Reference. 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. In Hindi in the simple and easy way. Outline four possible causes of the failures. Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). Portability: It makes the software portable by ensuring characteristics like hardware independency, software independency, adaptability, install-ability and reusability. Describe three advantages of the tool that could be influencing this trend. What is Non functional software Testing? For example: Latest Version of the platforms (software) Win 7 Win 8 Win 8.1 Win 10 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. Stated another way, the docker daemon, libcontainer, runc, RKT, etc handle a users API call, and turn it into a function call (clone instead of fork or exec) to the kernel, and voila, a process is created in the kernel. compatability testing is also known as protability testing. For Dev-ops, portability comes with stability. Mobile Compatibility Requirements Checking your software is compatible with mobile platforms like Android, iOS, etc. First, the work of organizing and creating a container is done in user space. Requirements that software must be compatible with other software. Vertical portability refers to consistency of software throught whole lifecycle, which can be ensured with Infrastructure as code. Please choose your preferred way, Issues in the Specification and Measurement of Software Portability. 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. Give two reasons for this. Although preference might be given to certain factors like performance, security in enterprise applications, fewer lines of code among other factors. Requirements analysis 3. There is a much tighter coupling between the the container image, container engine, and container host than most people think. True/False. Portable applications can be converted from one computer environment to another one. Portability - you can move the image where you want. i) Describe the type of maintenance that you would recommend for the information system. I think it is important to stress that this article will discuss not which is, the best OS because it is impossible to come to that conclusion.It's not as simple as comparing Linux and Unix considering how vastly . Compatibility - the container images and hosts are designed and engineered to work together (See: Engineering compatibility with the Red Hat Universal Base Image). 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. Others may feel that a significant amount of restructuring at the source level is still consistent with portability. SCORM can track learning that happens only on laptops or desktops. 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. on customer expected platforms or not. Supportability is based on a vendors ability to release, patch, version, and test a set of components together. Which of the following is a non functional requirement? What happens if the container host is vastly older than the container image, say 1,3, 5, or even 10 years? When the team visualizes the project details during the discovery (inception) phase, they may identify errors in the initial stage of development. 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) Differentiated between user guide manual and technical manual as used in system documentation, Outline two participant that could be invited for a structured walkthrough meeting, Outline three reasons that could influence a system designer to use functional decomposition, Decision trees are commonly used by system analyst. Supportability is based on a vendor's ability to release, patch, version, and test a set of components together. 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. This means you can share infrastructure like registry servers between cloud providers or on premise. Deep means how scalable and replicable your code/architecture/software is. 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. Hardware Compatibility Requirements are functional requirements? (i)Identify the training method that he would be using The Solaris operating environment runs on machines of all sizes, from laptops to supercomputers. This is what vendors can support. Portability - you can move the image where you want. Reason: Versions Compatibility Requirements are non-functional requirements. -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. Usability: It ensures the comprehensibility, communicativeness and ease of learning. This is foundational to the vision of hybrid and multi cloud. Testing 6. First, notice that Podman is able to mount the container image.

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. They also want too avoid lock-ins (on certain libraries or dependencies). This is important because recent versions of Microsoft Word have new features that aren't compatible with older versions. The above graphic shows all of the moving parts in a typical Kubernetes environment. (ii) Explain two problems that she could experience while using the fact-finding method identified in (i). No matter how hard you try, ARM binaries in a container image will not run on POWER container hosts. 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. 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. NET Core support multiple platforms like Windows, macOS & Linux whereas .NET Framework supports only Windows. Feel free to contribute. Describe three types of prototypes used in this industry, Explain the term bespoke system as applied in system acquisition, Marek company limited installed modern computer in all its offices but the existing information system could not be installed in the new computer. Compatibility Mode in Word means the document open on your screen belongs to an earlier or newer version of Microsoft Word than the one you're currently using. Browse Knowledgebase articles, manage support cases and subscriptions, download updates, and more from one place. 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. Outline two responsibilities of a system analyst in an organization 2. ISO 25010 ISO/IEC 25010 Compatibility Degree to which a product, system or component can exchange information with other products, systems or components, and/or perform its required functions while sharing the same hardware or software environment. Porting is no more than transferring specified directories and their contents. Originally posted at: http://crunchtools.com/deeply-understanding-the-different-between-portability-compatibility-and-supportability/, You are master of this field. Lets demonstrate that the container image format is the same no matter which type of artifact we pull by pulling a Windows Nano image down on a RHEL 8 container host. Sarah was required to select a system development method for a proposed information system for her company. Drive letters and the backslash as path delimiter are not accepted on all operating systems. Use case diagrams are popular in system analysis. Common Portability kinds are applicatiion, source code and data portability. This means you can share infrastructure like registry servers between cloud providers or on premise. How its possible to run Ubuntu containers on CentOS, or Fedora containers on CoreOS? Portability usually has 3 dimensons: Vertical (Development lifecycle), Horizontal (Platform/provider migration) or Deep (Replication). As to whether there is a certain intersection between portability and compatibility between various platforms, the following discussion is carried out. Portability in high-level computer programming is the usability of the same software in different environments. 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? Transferring installed program files to another computer of basically the same architecture. Software which is not portable in this sense will have to be transferred with modifications to support the environment on the destination machine. A nonfunctional requirement is an attribute that dictates how a system operates. : utime() fails under Windows with EACCES, when it is called for a directory). c)Antivirus. 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. How to speed up the software development process Software development process - conclusion This is a compatibility problem, even though the image is portable. A computer program is said to be portable if there is very low effort required to make it run on different platforms. What happens if the container image is vastly older than the container host, say 1, 3, 5, or even 10 years? When writing 32-bit code, you can use the 64-bit version of Office without any changes. How many 1.44MB diskettes would be used to store data that require storage space of 4.7 GB. 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. 1. For Sales teams, the main reason for porting is to reach wider audience. What happens if the glibc in your application, inside the container doesnt use hardware accelerated routines because the underlying kernel didnt enable it? 5G core adoption the open way with Red Hat OpenShift, Whats new with Quarkus? State two precautions that should be observed when installing a new piece of hardware into a computer system. View users in your organization, and edit their account information, preferences, and permissions. Horizontal stands for platform/dependency flexibility. Create more predictable projects. The term "software testability" has two related but different meanings: on the one hand, it refers to the ease with which a given test coverage criterion can be satisfied; on the other hand, it is defined as the likelihood, possibly measured statistically, that a set of test cases will expose a failure if the software is faulty. // Your costs and results may vary. Study with Quizlet and memorize flashcards containing terms like Another name for data that has meaning is: - mean data - wisdom - information - none of these is correct - data accuracy, The difference between wisdom and knowledge is that: - none of these is correct - wisdom is the synthesis of experience, insight, and reflection - wisdom is the result of data collection and interpretation . Devices Compatibility Requirements It checks the compatibility of your software with different devices like USB port Devices, Printers and Scanners, Other media devices, and Blue tooth. 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. ! 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?
