Implementing Continuous Integration/Continuous Deployment (CI/CD) Pipelines for Large-Scale iOS Applications

Continuous integration and continuous deployment pipelines have become essential components of modern software development, particularly in creating large-scale iOS apps. The automation of procedures for creating, testing, and deploying is facilitated by them, which results in an increase in both the speed and reliability of the release process. The complexity and scope of the codebase, the need for rigorous testing across a broad range of devices and operating system versions, and the regular necessity of updates to address bugs or bring new features all contribute to the conclusion that continuous integration and continuous delivery pipelines are an integral component of major iOS projects. The integration of continuous integration with continuous delivery provides developers with the assurance that code changes are automatically tested and delivered, hence lowering the need for human intervention, and reducing the chance of mistakes. In addition, this arrangement makes it possible to do parallel testing, which is useful when working with many test cases and device configurations. It is also possible to design continuous integration and continuous delivery pipelines to do tests for code quality, security scans, or other automated checks, which will ensure that the codebase is not compromised.By increasing communication among development teams, continuous integration and continuous delivery pipelines in big iOS projects provide yet another key advantage. It guarantees that every member of the team always has access to the most recent version of the code, which is essential in situations when many teams are working on various aspects or components of the application. In addition, continuous integration and continuous delivery pipelines enhance software quality by accelerating feedback loops, which enables engineers to resolve problems more expediently. Nevertheless, the establishment of continuous integration and continuous delivery pipelines for large-scale iOS apps involves several issues, such as the management of build times, the certification of compatibility with various devices, and the upkeep of the infrastructure. It is necessary to carefully design and optimize the CI/CD procedures to overcome these problems. This may be accomplished by choosing the appropriate tools and configurations adapted to the project's requirements.

Data Management for ML-Based Analytics and Beyond

The increasing capabilities of machine learning (ML) has enabled the deployment of ML methods in a variety of applications, ranging from unstructured data analytics to autonomous vehicles. Due to the volumes of data over which ML is deployed, it is infeasible for humans to monitor deployments: the Tesla fleet of vehicles produces exabytes of data and millions of hours of video per day. As a result, ML deployments can fail in unexpected and catastrophic ways. In this work, we highlight three important but underlooked aspects of ML deployment pipelines: (1) managing high-quality training data, (2) monitoring ML errors at deployment time, and (3) connecting end use to deployment algorithms. We first demonstrate that training labels are often erroneous, contrary to standard practice, even when labeled by leading vendors. We then demonstrate that standard methods of deploying ML methods can lead to downstream errors. As a first step toward addressing these issues, we review and contextualize two abstractions for finding errors in training data and deployments. We further describe how to improve algorithms for analytics queries as a case study for optimizing ML pipelines end to end.

Migration of Jenkins Pipeline to GitHub Actions

Moving your continuous integration and continuous deployment (CI/CD) pipelines from Jenkins to GitHub Actions offers several benefits, including savings and a more flexible and secure hybrid model. Jenkins installations usually use servers hosted in their own data centers, while GitHub operations offer a hybrid model where DevSecOps self-hosted runners can be used for secure workflows and open runners for other common workflows that handle less sensitive data/code. GitHub Actions and Jenkins share some similarities, making the transition to GitHub Actions relatively easy.

Integrating Cloud-Native Solutions in Financial Services for Enhanced Operational Efficiency

In an industry marked by fast technological advancement and strict regulatory demands, the incorporation of cloud-native solutions in financial services has become a crucial approach for improving operational efficiency. Cloud-native architectures, which are specifically designed to use the complete functionalities of cloud computing environments, provide substantial benefits compared to conventional on-premises systems. This study investigates the ways in which financial institutions might use these benefits to attain enhanced agility, scalability, and cost-efficiency. Cloud-native solutions are constructed by using microservices, containerisation, and continuous integration/continuous deployment (CI/CD) methodologies, offering organisations the ability to build applications with greater speed and efficiency. Through the use of these technologies, financial services companies may enhance their capacity to adapt to market fluctuations, optimise their information technology infrastructure, and refine their operations. Microservices enable the creation of modular application aarchitecture, which simplifies adjustments and maintenance processes while minimising periods of system unavailability. Containerisation, using infrastructure such as Docker and Kubernetes, improves the efficient use of resources and ensures consistent operation in various settings. Continuous Integration/Continuous Deployment pipelines optimise development cycles by facilitating regular upgrades and expediting the release of new features.

Continuous QoS-aware adaptation of Cloud-IoT application placements

Cloud-Internet of Things computing paradigms call for novel and efficient methodologies to decide where to place application services in continuity with Continuous Integration/Continuous Deployment pipelines and infrastructure monitoring. In this article, we present Continuous Adaptation (CA), a new DevOps practice for (1) detecting runtime changes in the application requirements or the infrastructure that, due to their change in resource consumption or their effects on the Quality of Service (QoS), can affect the validity and dependability of the current application placement, and for (2) locally intervening on them by suggesting new placements that ensure all (functional and non-functional) application requirements are met. We assess a prototype of CA, ConDADO, and analyze its performance over a motivating use case. ConDADO adapts the application placement to environmental changes through the use of continuous reasoning, reducing the size of the problem to be solved to optimize its performance. The evaluation shows that ConDADO is able to obtain nearly optimal QoS up to 4.2times faster than alternative techniques, also minimizing the cost of service migration.
