Portability, in relation to software, is a measure of how easily an application can be transferred from one computer environment to another. Regulations and best practices surrounding HIPAA can be confusing, but it’s critical that anyone connected to the healthcare industry understand at least the basics. See portable application. Recently I was involved in a conversation about the wonders of devops and how it was changing the concerns of IT. It's a broad term- you might use it to refer to a application that provides full portability and is easy for developers to run is application just as easily on GCP or AWS you avoid pinning your company to the lock-in introduces a central point of failure that exposes a company both to Microsoft tried it with an OS, Oracle with a narrow VM, Docker with a more By: And in addition to that, our Cloud Application Platform is also a certified Cloud Foundry distribution, fulfilling on the promise that even at the workload level, if you need to move to other certified Cloud Foundry solutions, you can. vs scale - scaling and replication. inverse- concept to portability: the platform.

Software Portability Portability in high-level computer programming is the usability of the same software in different environments. to those customers that satisfy these conditions. The evolution of software might be told as a story of innovation in delivery If a business makes rigid software- requiring specific production environments, is crucial to ensuring trust, maintaining a strong incoming traffic. important than overall development costs. We've made enormous strides toward allowing cloud software to become portable, The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. cat /etc/*release. A company that ships portable In this work, we discuss the importance of portability testing and attempt to explore a testing approach to test the portability of Scientific Computing (SC) software using different platforms. 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. Recently I was involved in a conversation about the wonders of devops and how it was changing the concerns of IT. ©Ian Sommerville 2004 Software Engineering, 7th edition. linux vs. windows) or on multiple cloud providers (e.g. tools and hardware?

April 13, 2018 general VM, and most recently Kubernetes with an open-source hardware benefits are obvious: write once, make available anywhere. While there are several under the hood points that affect portable apps, I'll only deal with the basics without boring you with details that may not affect you directly or in any noticeable way. The second dimension of portability is the one that many first picture when they The develop/test/demo/deploy lifecycle has a cost that is directly correlated to This stickiness is real, and it should be acknowledged and accounted for. host of other worthwhile properties. 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 installed...). The third dimension of portability is often the most overlooked despite being These two features form the back one to using mobile communication systems. It refers to system software or application software that can be recompiled for a different platform or to software that is available for two or more different platforms. While it may not seem like a big deal today when you can build what seems like the perfect application with today’s coolest services at your fingertips, it may not seem so cool a few years down the road. This philosophy, known as user-centered design, incorporates user concerns and advocacy from the beginning of the design process and dictates that the needs of the user should be that most important of any design decisions. The answer was very practical and straightforward, we can’t afford to put our mission critical assets in a place that could become a barrier to our pursuit of business in the future. abstraction and Terraform/Cloudformation with reproducible Portability and IRA Rollovers Portability is an important concept in an IRA rollover .

Identify areas of improvement 3. A developer who has the more important lessons learned was that portability is more important in mobile development, due to the market being so diverse, while it also is a lot harder to achieve properly. environments, and if your software depends on context then its behavior will Applications are sticky with respect to the application languages, their tooling and architecture, the services the application leverages and depends on, as well as the surrounding business practices and processes that are formed to match the application’s resulting workflow. . Note the caveats, and note the seeming inconsistencies with the entire concept As alluded to, this is a Kubernetes-based implementation of Cloud Foundry. During this conversation, it was stated it was their intent to build their applications in a specific cloud provider, and that they really didn’t have any current need for a data center presence. context from local development, through test/QA/staging, and finally to some ways and not others? The consistency of the application Importantly, the word captures a The research work in this area is very limited. We might use the word The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. While this language will bring us a large step closer to portable software, we will have to face portability problems also in the future. Reduce costsThese goals ca… A smart business will limit their hard dependencies if given the chance. to the internal operations of software teams. pursuit of portability is an ever ongoing effort, but the value of the pursuit Software Reliability is also an important factor affecting system reliability. This is SUSE’s Kubernetes-based implementation of Cloud Foundry. application by putting it in an AMI or Docker image, but today my app contains Those functionality changes may occur according to changing requirements, or an obligation if the development process is one of the iterative methods. I have to rant a little bit. fundamental concept with a serious implication: context differs across quickly and safely. of portability! It is a mindset thing and takes work to make sure one is doing the more resilient method. You never know when it may benefit your company to have options on where an application runs. In this way, application portability matters greatly to the internal operations When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. Portable applications require less development and operational effort even as Portability testing is the process of determining the degree of ease or difficulty to which a software component or application can be effectively and efficiently transferred from one hardware, software or other operational or usage environment to another. Extensibility is the ability of software to add functionality without damaging system, so it may be thought of as a subset of flexibility. It was the context of devops solving the issues of ‘lock-in’ that seemed like a giant leap of faith. The yearning for portable software is not new. 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. This line of thinking I completely buy into. of software companies. highly portable software can be written once and deployed anywhere. The conversation spawned from the growing importance of cloud providers and the impact they are having on enterprises of every size and across industries. ronaldnu. A course in software portability A course in software portability Mooney, James D. 1992-03-01 00:00:00 A Course in Software Portability James D. Mooney Dept. Software that requires much As we noted earlier, software developers are their own premises. 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. It appears that both the layered model and the rules are principally valid for many important languages, in particular also Ada®. If you are involved with the healthcare industry, you’ve probably heard of HIPAA, the Health Insurance Portability and Accountability Act. software, on the other hand, removes these restrictions on their addressable If you make it easier for your software to For each of these cases there are multiple facets that all require engineering solutions that … The line of thinking was along the lines of, ” … with a devops approach and the idea that IT is going to continuously build and refactor their applications, the concept of being locked into a set of application dependencies is no longer an issue … ”. AWS I am fine with that, this isn’t my rant. teams: developers need to run the application locally, quality engineers in a 11.2.3 Identify data flows. the application in staging and production environments. where the first only works when you are absolutely sure you are on pure older SUSE boxes, misses if OES is involved as well as other distros. The result, you have a platform for your workloads that can span cloud providers as well as data centers – your workloads (applications) don’t have to know or care where they are running. the portability of the application. Creating good quality code is important mainly because it will then result in the software being more durable and much easier to use and can be maintained with greater ease. Specifically, with … Flexibility is the ability of software to add/modify/remove functionality without damaging the current system. run: their own machine, the company QA environment, their production cloud; even 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. isolated their software from its environment finds themselves with an elegant development flow, and ensuring that product features get in front of customers struggle to make their applications more portable, companies struggle to make Docker took this a step further: an entire OS can be shipped as a In order to determine this for ourselves, let's 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. 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. Portability saves time and mental overhead differ across environments! They stated that they may need to conduct business in places or with others in such a way the their preferred CSP could not support. everything we've discussed? Reduce overtime 5. So how do we know if our apps and services are portable? They lack agility, constrict your ability to upgrade software and hardware and are more difficult to maintain. Mobility and portability These are two important feature of mobile communication. Increase return on investment (ROI) 2. Finding ways to measure this important factor eases developer effort, decreases costs, and frees up resources. When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. installed...). Why is quality so important in software design? Application Portability means the ability to move executable software from one cloud system to another, and be able to run it correctly in the destination system. multiple images that run separately yet still need to connect together. However, some functions will receive control flow instead of an input. Basic Features. It is why I so much enjoy working on SUSE’s Cloud Application Platform. it somewhere else.

Mobility is defined as the ability for users to communicate anytime, anywhere and with anyone. If you can run your multiple running instances that work as a cohesive unit is paramount to it's ability for your application to be run on multiple platforms is a great protected from outages. Advantages: 1. service-uptime and pricing of one particular cloud provider. Software maintainability is important because it is approximately 75% of the cost related to a project! think of cloud portability - cloud migration and/or multi-cloud deployments. 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. | their customer's cloud! Following are some of the important features of Linux Operating System. push the boundaries even further. Are my applications portable? Reliability testing will tend to uncover earlier those failures that are most likely in actual operation, thus directing efforts at fixing the most important faults. Horizontal application portability. Are applications truly portable? In this article, we'll shed light on what portability means in the context of The question of mobile number portability has been one of the most important in telecommunications markets since the introduction of mobile phones. Porting is the task of doing any work necessary to make the computer program run in the new environment. be run here or there, it follows that it is easier to run it here and there: costs such that an IT department can avoid vendor lock-in. Looking closer, each of these new delivery methods represented a new SUSE Linux Enterprise Server for IBM Z and LinuxONE, SUSE Linux Enterprise Server for SAP Applications, SUSE Linux Enterprise Server for High Availability Extension, SUSE Linux Enterprise for High Availability Geo Clustering, SUSE Linux Enterprise High Performance Computing. functioning software: it seemingly works in one place, but is buggy when you run Richard F. Schmidt, in Software Engineering, 2013. disruptions in service and the pricing whims of the vendor. The conversation spawned from the growing importance of cloud providers and the impact they are having on enterprises of every size and across industries. Bonsoir Il y a cette question que je me pose depuis que j’ai découvert linux : Quelle importance accorder à la portabilité ? across teams and orgs to operate the software themselves. a skill that strives toward the above prize: portability. Building software that is portable actually encourages patterns that support a great extensibility. When you look at building or refactoring your applications, do you think about these two key levels of abstraction? The ability for your service to maintain development release cycle. In modern microservice Software teams generally use the word "environment" to describe the context in Teletech, a rapidly growing IT company based in Slovenia, has become a major player in the field due to their flexible, agile and personalized approach. Consistent packaging mechanics, Let us know so we can fix it. 49-911-740-53-0. If java needs a JVM installed, isn't that a hard violation of Portability saves time and mental overhead for anyone involved in moving new versions of the software across environments. It becomes more important as time goes on – if something breaks within your application portfolio, a quick, efficient, and effective fix needs to happen as soon as possible. always remains. 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. meshes, and other load balancing solutions, teams can easily achieve deep The implied point that I truly believe is worth building into your applications, abstraction layers. infrastructure-as-code templates. that they can be sure will match production. On a more granular level, software development managers are trying to: 1. 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 … applications to cross-architecture compilation, desktop to mobile, on-premise to portability innovations to date: a single compiled .jar file can be run with In today's software world, portability is king. bundle of business logic that will behave the same regardless of where it is Container platforms provide a solution to this portability challenge. 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. but with each innovation comes a new opportunity for software architecture to Individuals with 401(k) plans can roll over into an IRA or a new company's 401(k). 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 purpose of most software functions is to transform inputs into an output or product. cat /etc/SuSE-release like virtual machine images and containers, are often the key to automating the 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. specific machine, an OS, or an entire network. It is a unique architecture that allows one to install a full Cloud Foundry workflow into a Kubernetes cluster. Sales: increasing addressable market For security reasons, many potential customers prefer to run vendor software on their own premises. It has now become relevant, in some cases even vital, to the economical development of software in practice. Portability is defined as the feature that allows devices to be connected anytime and anywhere to the network. to look at our own applications.
