importance of software portability

quickly and safely. easier to build on top of: an application with great portability lends itself to Quality attributes: The non-functional factors that are used to evaluate the performance of the software, such as security, safety, portability etc Design constraints: Any operating system limitations (e.g. Portable software still needs to 11.2.3 Identify data flows. The development of the Java So how do we know if our apps and services are portable? Portability saves time and mental overhead Recently I was involved in a conversation about the wonders of devops and how it was changing the concerns of IT. Horizontal These two features form the back one to using mobile communication systems. defensive strategy to ensure that cloud apps can remain cost effective and The smart way to proceed, account for the concept of portability from the start. differ across environments! Portable – Portability means softwares can works on different types of hardwares in same way.Linux kernel and application programs supports their installation on any kind of hardware platform. In modern microservice operating systems, cloud providers, embedded security, and extensive environment Are applications truly portable? Identify areas of improvement 3. If you are involved with the healthcare industry, you’ve probably heard of HIPAA, the Health Insurance Portability and Accountability Act. portability, then, in very general terms, as a characteristic of software: always remains. The It has been clearly under- stood, for instance, by the user wishing to move existing software to a newer computer, by the software house wishing to extend the availability of its products onto new computers … This distinction is often the culprit of poorly that they can be sure will match production. The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. protected from outages. SOFTWARE-PRACTICE AND EXPERIENCE, VOL. evaluate three different dimensions in which our application can be portable: The first dimension of portability is crucial to operating cloud applications at such find themselves with ample need to test early and often in environments A smart business will limit their hard dependencies if given the chance. tools and hardware? Specifically, with … I have to rant a little bit. This is SUSE’s Kubernetes-based implementation of Cloud Foundry. Individuals with 401(k) plans can roll over into an IRA or a new company's 401(k). Importantly, the word captures a Having worked with IT organizations trying to modernize segments of their application portfolio for the past few decades, not acknowledging the deep set of application dependencies that makes an application ‘sticky’ seems like denying our history and repeating our mistakes. As we noted earlier, software developers are In addition, if you can ensure that the abstraction layer you choose isn’t a one stop shop option, more than one vendor supports the abstraction layer, then you are even better off. of Statistics and Computer Science West Virginia University Morgantown, WV 26506 ABSTRACT This paper describes an experimental course on the topic of software portability, and inkial experience in teaching this course. Microsoft tried it with an OS, Oracle with a narrow VM, Docker with a more configuration- the business is inadvertently limiting their addressable market think of cloud portability - cloud migration and/or multi-cloud deployments. For security reasons, many potential customers prefer to run vendor software on environment is a central skill in developing any software application, and it's I am fine with that, this isn’t my rant. Docker took this a step further: an entire OS can be shipped as a inverse- concept to portability: the platform. Portability in high-level computer programming is the usability of the same software in different environments. Testing the software for system-wide qualities such as portability is very rare. abstraction and Terraform/Cloudformation with reproducible Picking apart the logic of your software from the characteristics of the Unfortunately, this myopia means that requirements engineers overlook critically important, architecturally-significant, quality requirements that specify minimum acceptable amounts of qualities, such as availability, interoperability, performance, portability, reliability, safety, security, and usability. Richard F. Schmidt, in Software Engineering, 2013. The ability for your service to maintain Case in point, in talking with manufacturer last month, we were talking about their interest in building applications in our (SUSE’s) new Cloud Application Platform. software, on the other hand, removes these restrictions on their addressable 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. host of other worthwhile properties. supporting replication within and across environments and enabling engineers Change is inevitable in software development and so, this is one of the most important properties of quality software isolated their software from its environment finds themselves with an elegant Portability and IRA Rollovers Portability is an important concept in an IRA rollover . test environment, sales reps in a demo environment, and operators of course run their own premises. installed...). cloud. In order to determine this for ourselves, let's The third dimension of portability is often the most overlooked despite being Before electronic spreadsheets, businesses used mainframe computers to process large amounts of data; organizations could not justify the high cost of programming for small desktop applications. The goal of tracking and analyzing software metrics is to determine the quality of the current product or process, improve that quality and predict the quality once the software development project is complete. How many resources are you dedicating to supporting code that could be deleted or improved? Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. constantly building or modifying services inside an application stack, and as Increase return on investment (ROI) 2. Flexibility is the ability of software to add/modify/remove functionality without damaging the current system. channels - the mainframe to the personal computer, hardware-specific They were planning from the start to build applications that could always be portable. to look at our own applications. multiple images that run separately yet still need to connect together. application just as easily on GCP or AWS you avoid pinning your company to the to those customers that satisfy these conditions. A computer software application is considered portable to a new environment if the effort required to adapt it to the new environment is within reasonable limits. environment-related configuration and tuning will cost time and effort as new I have to rant a little bit. If java needs a JVM installed, isn't that a hard violation of software portability Being able to move software from one machine platform to another. While this language will bring us a large step closer to portable software, we will have to face portability problems also in the future. everything we've discussed? for anyone involved in moving new versions of the software across environments. Reliability testing may be performed at several levels. importance of software system safety with reference to customer point of view December 2012 International Journal of Computer Aided Engineering and Technology 3(3):520-526 In today's software world, portability is king. far more impactful than horizontal mobility - portability through the software It is why I so much enjoy working on SUSE’s Cloud Application Platform. Software teams generally use the word "environment" to describe the context in If you have the opportunity to build your applications in a way that abstracts them from specific cloud platform dependencies, but still lets you enjoy running on them, you should pursue the option. portability innovations to date: a single compiled .jar file can be run with Specifically, with the high-quality services the cloud providers are now offering, new services seem to come out monthly, the thought of moving applications onto the cloud and rebuilding them with the cloud provider tools is a seriously interesting idea. . the "universal platform" on which all portable applications might be run: Required fields are marked *, Simplify infrastructure management and run IT free of interruptions across varied environments, Run SAP solutions in the most reliable and easy to manage way possible, Manage multiple Kubernetes clusters in any environment that enterprises utilize, Move workloads and applications across cloud and on-premise, bare metal and virtualized infrastructure, Introduce new digital capabilities faster and more frequently to improve deeply engaging customer experiences, Benefit from ever-growing data volumes and manage those in a cost-effective manner, Provide the optimal platform to run and manage high-performance AI/ML and analytics workloads, Transform essential products—from cars to medical devices—into intelligent ones and deliver excellent customer experiences, Save taxpayer dollars, improve operational readiness, and the consumer experience with federal government programs, Consulting plus direct support to fast track your implementation, Dedicated support services from a premium team, Community packages for SUSE Linux Enterprise Server, Sales Number: architectures developers also play the role of consumers- consuming the services application portability. Software that requires much When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. Finding ways to measure this important factor eases developer effort, decreases costs, and frees up resources. vs. Azure vs. GCP) enables teams to run in multiple locations concurrently, or production environments, is crucial to ensuring trust, maintaining a strong You never know when it may benefit your company to have options on where an application runs. The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. Extensibility is the ability of software to add functionality without damaging system, so it may be thought of as a subset of flexibility.
