The ecosystem of the Internet of Things is a set of physical devices such as sensors and actuators. It includes a set of servers and gateways that provide connectivity. These devices can be installed at three levels: the edge level, the fog level, and the cloud level. Applications that monitor things and collect data from sensors are deployed at the edge, fog, and cloud levels. These applications can be containerized and deployed in different devices by Docker, which takes advantage of its advantage to create executable containers that are isolated from each other. This paper presents a generic Meta-model of the Internet of Things ecosystem based on microservices and supported by Docker as a containerization tool, Ansible as a monitoring tool and Kubernetes as scaling tool. This Meta-model allows us to generate a system of connected objects that can be deployed on three levels: Fog, Edge, Cloud. This Meta-model can be used in different types of domains such as Smart Home-Smart City-Smart Vehicle-Smart Health-Smart Farm-Smart Factory. The Meta-model proposed in this article is a fusion between 5 Meta-models: Internet of Things-Microservices-Ansible-Docker-Kubernetes.

Continuous delivery (CD) has emerged as an auspicious alternative to traditional release engineering, promising to provide the capability to release valuable software continuously to customers. Paddy Power has been implementing CD for the past two years. This article explains why Paddy Power decided to adopt CD, describes the resulting CD capability, and reports the huge benefits and challenges involved. These experiences can provide fellow practitioners with insights for their adoption of CD, and the identified challenges can provide researchers valuable input for developing their research agendas.

When to adopt DevOps?

DevOps should be used for large distributed applications such as eCommerce sites or applications hosted on a cloud platform.
When not to adopt DevOps?

It should not be used in a mission-critical application like bank, power and other sensitive data sites. Such applications need strict access controls on the production environment, a detailed change management policy, access control policy to the data centers.
DevOps Lifecycle

DevOps is deep integration between development and operations. Understanding DevOps is not possible without knowing DevOps lifecycle.

Here is a brief information about the Continuous DevOps life-cycle:

1. Development

In this DevOps stage the development of software takes place constantly. In this phase, the entire development process is separated into small development cycles. This benefits DevOps team to speed up software development and delivery process.

2. Testing

QA team use tools like Selenium to identify and fix bugs in the new piece of code.

3. Integration

In this stage, new functionality is integrated with the prevailing code, and testing takes place. Continuous development is only possible due to continuous integration and testing.

4. Deployment

In this phase, the deployment process takes place continuously. It is performed in such a manner that any changes made any time in the code, should not affect the functioning of high traffic website.

5. Monitoring

In this phase, operation team will take care of the inappropriate system behavior or bugs which are found in production.
DevOps Work Flow

Workflows provide a visual overview of the sequence in which input is provided. It also tells about actions are performed, and output is generated for an operations process.

The concept of DevOps is a hot topic in recent years. DevOps is a collection of methods for developers and collaborates to deliver software and services rapidly, reliably and with higher quality. The concept of 'lean' defines a kind of the operation in the Toyota Production System. Continuous Integration (CI) and Continuous Delivery (CD) are one of the important practices in the software development. CI is one of the agile software development practice that involves automation and frequent integration of the software changes. DevOps and CD are another subset of the agile. DevOps could be extended with agile methods and by using patterns and practices it helps to improve collaboration between development and operation teams. Both development models of agile and lean are similar to in terms of goals by focusing on the customers and responding to their needs in a rapid method. Agile software development focuses on the software development function, but Lean Thinking has a very explicit focus on the end-to-end process. In this review article, the principle and practices of DevOps, reasons for its usage, challenges of DevOps, the relationship of DevOps with agile are studied.

NOTE: Direct work on this has ceased. See https://www.academia.edu/29807815/Renewing_the_IT_Curriculum_Responding_to_Agile_DevOps_and_Digital_Transformation....

The use and importance of information technology is accelerating throughout the economy, a movement known as " digital transformation. " New delivery techniques are emerging, oriented around a core of Agile software development. Agile as a movement has extended its reach into product management, operations, IT infrastructure, and many other aspects of management information systems, notably in the recent movement termed " DevOps. " Older practices such as waterfall software development, project management, and IT process frameworks are falling into disfavor. Workforce requirements are shifting, and there is a need for an updated educational response more consistent with digital trends. A new learning progression based on a " scaling " narrative is proposed as a basis for reference curricula.

Este artigo partiu de uma ideia com base na publicação 50+ Useful DevOps Tools de Agustin Romano e não é minha intenção tomar a autoria de outra obra. O que fiz neste trabalho foi realizar uma tradução e em muitas oportunidades a complementação de dados faltantes nos assuntos abordados e atualização para a realidade. Nesta versão constam 65 ferramentas.

Optimizar y racionalizar el uso de los recursos TI, hoy día significa elegir una arquitectura abierta y escalable en nube. Siguiendo los principios establecidos por ITIL, el presente proyecto de intervención plantea una solución práctica IaaS, desarrollada con contenedores de Docker hospedados en la nube pública de Google Cloud. Ello permitió a una empresa editorial de tamaño mediana, especializada en la publicación de periódicos, resolver varios problemas de capacidad (escalabilidad y desempeño de su portal informativo). Balanceando el crecimiento de la demanda y los recursos computacionales, sin incurrir en costes adicionales, logrando una reducción del 50% y una mejora en los tiempos de respuesta promedios del 30%, gracias a las
enormes capacidades y oportunidades que la arquitectura propuesta ofrece: corre lo mismo en ambientes de desarrollo y producción (DevOps), es sencillo montar una imagen de Docker y conectarla con otro contenedor que tenga una base de datos, como MySQL y permite aprovechar al máximo las capacidades del sistema operativo host al evitar la sobrecarga inherente a una máquina virtual. Todo ello justifica el desarrollo del presente proyecto de intervención, donde se lleva el concepto de innovación al extremo, enfatizando las ventajas de pasar de un modelo Capex (Capital expenses) a un modelo Opex (Operational expenses), con todas las
ventajas inherentes.

You could think of DevSecOps (development, security and operations) as the evolution of DevOps, a modern approach that bridges the gap between development and operations. The addition of "security" to the movement emphasizes the importance of security working with development and operations from Day One. Learn more in a DevSecOps Training course by Tonex.

Resumo. ​ Um grande problema que afeta a qualidade do desenvolvimento é a realização de tarefas importante para a entrega de software que são executadas manualmente. Este artigo tem o objetivo de mostrar boas práticas de desenvolvimento que vem sendo estudadas ha várias décadas para fornecer ao mundo uma alternativa às metodologias pesadas e altamente dirigidas por documentação, permitindo aumentar a capacidade de liberar versões do sistema sob demanda, de gerar releases bem-sucedidos e implantar o sistema em qualquer ambiente simplesmente apertando um botão, sem precisar se preocupar se funcionará ou não. Abstract. A major problem that affects the quality of development is important for the realization of software delivery tasks that are performed manually. This article has the objective of show good development practices that have been studied for several decades to provide the world an alternative to heavy and highly targeted methodologies for documentation, allowing an increased ability to release versions of the system on demand, to generate well-releases successful and deploy the system in any environment by simply pressing a button, without having to worry if it will work or not.

Continuous Delivery (CD) is a relatively new software development approach. Companies that have adopted CD have reported significant benefits. Motivated by these benefits, many companies would like to adopt CD. However, adopting CD can be very challenging for a number of reasons, such as obtaining buy-in from a wide range of stakeholders whose goals may seemingly be different from—or even conflict with—our own; gaining sustained support in a dynamic complex enterprise environment; maintaining an application development team's momentum when their application's migration to CD requires an additional strenuous effort over a long period of time; and so on. To help overcome the adoption challenges, I present six strategies: (1) selling CD as a painkiller; (2) establishing a dedicated team with multi-disciplinary members; (3) continuous delivery of continuous delivery; (4) starting with the easy but important applications; (5) visual CD pipeline skeleton; (6) expert drop. These strategies were derived from four years of experience in implementing CD at a multi-billion-euro company. Additionally, our experience led to the identification of eight further challenges for research. The information contributes toward building a body of knowledge for CD adoption.

DevOps changes how individuals think about their work; DevOps values the diversity of work done, supports intentional processes that accelerate the rate by which businesses realize value, and measures the effect of social and technical change.

Continuous Delivery (CD) has emerged as an auspicious software development discipline, with the promise that it can provide the capability to release valuable software continuously to customers. Our organization has been implementing CD for the last two years. We have moved 22 software applications to CD. I noticed that CD has created a new context for architecting these software applications. This paper makes an initial attempt to answer the following questions: 1) what are the characteristics of this CD context; 2) why we want to architect for CD; and 3) what architecting for CD implies. The answers can provide fellow practitioners with insights for architecting their software applications for CD, and provide researchers with valuable input for developing their research agendas.

Efficiency and productivity are the fundamental pillars to build any business's success. We all are familiar with the adage that " Time Is Money" most organizations do not appreciate how this simple observation can run.

If business management of the organization focus on the effectiveness of their operations, understands and improves workflow, and identifies the inefficiencies ensures success.

Efficiency matters for any firm. Software development is one of the businesses that focus on the concept of DevOps. Undoubtedly, everyone is aware of DevOps, even if most organizations do not even move forward to provide the onboard opportunities. But many industries are under the impression that it's another buzzword.

In reality, Every software development team in any organization should be using DevOps. However, implementing DevOps requires full assistance of the DevOps consultancy service to make your transition process go smoothly.

If you're struggling to get releases through the pillars of poor IT infrastructure and silos, the DevOps methodology can do the best for you. Use the correct way to implement this to get release updates multiple times a day with the tiniest fraction.

Key Business Advantages Of DevOps

DevOps contains a set of practices that offer a quick route for businesses to convert yesterday's fiction into reality in software development. DevOps helps the developers to improve the speed of different business processes to gain control of automation and testing to create a high-quality product.

Wait!! That does not end here. DevOps helps improves statistics and produce better products at a quicker rate. DevOps implementation affects almost all areas of the organization positively. The DevOps consulting companies improve the satisfaction, work culture, and productivity of the business.

So we have gained a clear understanding of the advantages that DevOps brings to development businesses. Let's move forward now to look at the importance of a DevOps consultant in detail.

Role Of DevOps Consultant

Of course, executing DevOps was as easy as deciding to do it and informing your workforce to follow it. In reality, implementing DevOps should be a gradual and well-managed process. Anybody who wants to jump into it while unprepared will surely face issues implementing the DevOps methodology. Hiring DevOps experts is a great choice to make a smooth transition.

A DevOps consultant will guide your organization and you throughout the whole process. They ensure that you do not lose the momentum and rush the halfway. DevOps consultant brings the kind of professionals and in-depth knowledge that not be replaced.

It's a simple practice for DevOps consultants to stand out with an organization until they succeed in implementing new techniques. It might take some time, but DevOps gives the worth services.

Cost-Effective Services

DevOps implementations require a deeper understanding of the concept. A DevOps consultant is not very cheap, but it offers cost-effective ways to make the transition. In addition, a DevOps consultant offers custom-tailored made solutions to meet business-specific needs and goals.

Take professional help to reduce your stress substantially. Working without the advice of a DevOps consultant creates confusion and unnecessary tension.

Integrated Approach

The organization never took benefits from DevOps unless the whole team is on board. It's not working appropriately when half of your workforce follows the DevOps while the other is still working on old procedures. It needs to be implemented properly. DevOps slowly reduces the technical debt through inefficient coding practices.

DevOps consultants outline a viable system timeline to introduce the new processes to the workforce. They start working on implementation to ensure that everyone is progressing at the same rate. Plus, it also gives them peace of mind with the new practices that impact their performance dramatically.

Authentic Assessments

The main factor of DevOps consulting is the depth of assessment of business processes. Moreover, DevOps consultants research to find the present development policies and approaches that work on problem-solving collaboration.

After this information, they guide the business workforce to understand the aspect of DevOps to establish and achieve what they want from implementation results.

A detailed holistic assessment is a key to getting the full advantages of hiring a DevOps consultant, and it is one of the best reasons to take this approach. This assessment doesn't just provide the information about the development practices, it will also give a great indication of the overall health of your business.

Final Thoughts

DevOps is not just a new concept, it is much more than just the buzzword in software development. Without a DevOps consultant to handle transition is quite risky, and you are missing many of the benefits provided by the DevOps.

DevSecOps is a more than just getting security testing integrated into a pipeline and using the results to influence flow. Real success with DevSecOps comes when you are able to identify and measure critical aspects of your risks as well as your security controls and functions. It means that you have governance that enables and encourages the right behaviors – not just inhibits bad ones and you have an audit function that can measure this success. It also means you are able to incorporate and include security related information from all parts of the SDLC – including threat, design, testing and at runtime. Many places have achieved higher degrees of automation and education within their DevSecOps initiatives, however this needs to be an improving and continuous cycle. Taking it to the next level involves intensify these efforts with accurate threat analysis, secure design, measuring, governance and audit. Join us as we share insights on how organizations are moving beyond DevSecOps and more towards real Continuous Security.

Software system engineering is rapidly growing to larger scales and software maintenance tends to be complex. The number of involving software artefacts increases with the growth of software systems. Thus, different software development methodologies, processes and practices are getting introduced to ease the software management. Consequently, the management of excessive software artefacts is also important towards a successful maintenance. Therefore, the notion of traceability management of software artefacts is given prominence along with continuous integration. This paper explores the existing traceability management approaches to propose an optimized framework that overcomes current limitations. Hence, the previous work of this research, SAT-Analyzer, which is a prototype tool, is extended to support continuous integration with DevOps practices.
