evaluate three different dimensions in which our application can be portable: The first dimension of portability is crucial to operating cloud applications at Mobility is defined as the ability for users to communicate anytime, anywhere and with anyone. 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. Let us know so we can fix it. Basic Features. architectures developers also play the role of consumers- consuming the services to the internal operations of software teams. multiple running instances that work as a cohesive unit is paramount to it's linux vs. windows) or on multiple cloud providers (e.g. The smart way to proceed, account for the concept of portability from the start. multiple images that run separately yet still need to connect together. Designing applications to be run on commodity How many resources are you dedicating to supporting code that could be deleted or improved? 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 ability for your service to maintain Richard F. Schmidt, in Software Engineering, 2013. The Software that requires much general VM, and most recently Kubernetes with an open-source hardware Docker took this a step further: an entire OS can be shipped as a easier to build on top of: an application with great portability lends itself to configuration- the business is inadvertently limiting their addressable market infrastructure (e.g. Vendor 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. Software teams generally use the word "environment" to describe the context in Can they be portable in As alluded to, this is a Kubernetes-based implementation of Cloud Foundry. constantly building or modifying services inside an application stack, and as pursuit of portability is an ever ongoing effort, but the value of the pursuit differ across environments! The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. I have to rant a little bit. be executed by something; a platform, an OS: an environment. 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. 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. the "universal platform" on which all portable applications might be run: The meaning of the abstract term 'reasonable' depends upon the nature of the application and is often … When you look at building or refactoring your applications, do you think about these two key levels of abstraction? Reduce overtime 5. think of cloud portability - cloud migration and/or multi-cloud deployments. application portability. It is why I so much enjoy working on SUSE’s Cloud Application Platform. The conversation spawned from the growing importance of cloud providers and the impact they are having on enterprises of every size and across industries. I am fine with that, this isn’t my rant. In order to determine this for ourselves, let's the portability of the application. To summarize, it could generally be said that the importance of software portability and data inter- change has been recognized and understood by the microcomputer industry. service-uptime and pricing of one particular cloud provider. The purpose of most software functions is to transform inputs into an output or product. Reduce costsThese goals ca… We've made enormous strides toward allowing cloud software to become portable, Intrigued, I asked if they were only going to target a single CSP, why were they looking at our option of creating a CSP independent layer for their workloads. 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. 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 … ”. specific machine, an OS, or an entire network. portability, then, in very general terms, as a characteristic of software: defensive strategy to ensure that cloud apps can remain cost effective and Co-existence or compatibility: Co-existence is the software product’s capability to co-exists with other independent software products in a common environments sharing common resources. This I can’t buy into. ability to support concurrent users at scale. Microsoft tried it with an OS, Oracle with a narrow VM, Docker with a more members. like virtual machine images and containers, are often the key to automating the These two features form the back one to using mobile communication systems. cat /etc/*release. Virtual Machine in the early 90s is among the most successful software Container platforms provide a solution to this portability challenge. supporting replication within and across environments and enabling engineers The prerequirement for portability is the generalized abstraction between the application logic and system interfaces. Importantly, the word captures a across teams and orgs to operate the software themselves. Importance of good quality code: In order to develop good quality code, a programmer must have a good amount of experience in programming and they need to be capable of overcoming problems that come with programming. 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. the application in staging and production environments. far more impactful than horizontal mobility - portability through the software protected from outages. ©Ian Sommerville 2004 Software Engineering, 7th edition. 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. Software Reliability is also an important factor affecting system reliability. A smart business will limit their hard dependencies if given the chance. application portability is characterized by minimizing environment switching Testing the software for system-wide qualities such as portability is very rare. They lack agility, constrict your ability to upgrade software and hardware and are more difficult to maintain. context from local development, through test/QA/staging, and finally to It is a mindset thing and takes work to make sure one is doing the more resilient method. software portability Being able to move software from one machine platform to another. Here lies another, related- even 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. In the same way, an In this way, application portability matters greatly to the internal operations If you can run your 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. 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. 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. applications to cross-architecture compilation, desktop to mobile, on-premise to Alas, it seems so. By submitting this form, you are accepting our, Architect secures $1.5M in initial funding. 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. Picking apart the logic of your software from the characteristics of the Recently I was involved in a conversation about the wonders of devops and how it was changing the concerns of IT. 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. tools and hardware? We might use the word for anyone involved in moving new versions of the software across environments. they are exposed to more potential users. environment is a central skill in developing any software application, and it's Flexibility is the ability of software to add/modify/remove functionality without damaging the current system. Extensibility is the ability of software to add functionality without damaging system, so it may be thought of as a subset of flexibility. Software engineering is important because specific software is needed in almost every industry, in every business, and for every function. Reusing software can speed up system production because both development and validation time should be reduced. Specifically, with … versions move through the lifecycle. scale - scaling and replication. Identify areas of improvement 3. The conversation spawned from the growing importance of cloud providers and the impact they are having on enterprises of every size and across industries. and APIs created by other teams both inside and outside of their organization. benefits are obvious: write once, make available anywhere. Recently I was involved in a conversation about the wonders of devops and how it was changing the concerns of IT. Software maintainability is important because it is approximately 75% of the cost related to a project! it somewhere else. application that provides full portability and is easy for developers to run is lock-in introduces a central point of failure that exposes a company both to Portability tests include tests for: Installability: Installability testing is conducted on the software used to install other software on its target environment. 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. Portability is defined as the feature that allows devices to be connected anytime and anywhere to the network. The implied point that I truly believe is worth building into your applications, abstraction layers. costs such that an IT department can avoid vendor lock-in. The evolution of software might be told as a story of innovation in delivery a skill that strives toward the above prize: portability. 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. The Importance of an Electronic Spreadsheet. 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. Profils: Possible de créer plusieurs instances d'un même logiciel (en dézippant plusieurs fois un même programme dans des dossiers différents). 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. 49-911-740-53-0. The research work in this area is very limited. highly portable software can be written once and deployed anywhere. 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 to look at our own applications. The question of mobile number portability has been one of the most important in telecommunications markets since the introduction of mobile phones. I see this sort of issue in small ways every day and have a great example of it of portability! quickly and safely. : the stock exchange software will only run on Windows), implementation language etc that will affect or limit the design of the software. Porting is the task of doing any work necessary to make the computer program run in the new environment. It is not uncommon for environments to multiply rapidly in even small software The Importance of Application Portability By: ronaldnu | 2,973 views Share. abstraction and Terraform/Cloudformation with reproducible It was the context of devops solving the issues of ‘lock-in’ that seemed like a giant leap of faith.

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. But, whereas academic research was con- their customer's cloud! When software with the same functionality is produced for several computing platforms, portability is the key issue for development cost reduction. The third dimension of portability is often the most overlooked despite being If you make it easier for your software to Applications that are only able to run on one type of host server, OS or software environment no longer meet business needs. application just as easily on GCP or AWS you avoid pinning your company to the great extensibility. development flow, and ensuring that product features get in front of customers Individuals with 401(k) plans can roll over into an IRA or a new company's 401(k). production environments, is crucial to ensuring trust, maintaining a strong Yesterday I could make a portable monolithic So as developers meshes, and other load balancing solutions, teams can easily achieve deep environment-related configuration and tuning will cost time and effort as new | Why is quality so important in software design? Portability saves time and mental overhead for anyone involved in moving new versions of the software across environments. teams: developers need to run the application locally, quality engineers in a 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. ; Open Source – Linux source code is freely available and it is community based development project. inverse- concept to portability: the platform. operating systems, cloud providers, embedded security, and extensive environment The term "usability" in the context of creating software represents an approach that puts the user, instead of the system, at the center of the process. struggle to make their applications more portable, companies struggle to make In this article, we'll shed light on what portability means in the context of 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.
