Management Challenges for DevOps Adoption within UK SMEs
The DevOps phenomenon is gathering pace as more UK organisations seek to leverage the benefits it can potentially bring to software engineering functions. However substantial organisational change is inherent to adopting DevOps, especially where there are prior and established methods. As part of a wider piece of doctoral research investigating the management challenges of DevOps adoption, we present early findings of a six month qualitative diary study following the adoption of DevOps within a UK based SME with over 200 employees. We find that within our case study organisation, the DevOps approach is being adopted for the development of a new system used both internally and by customers. DevOps, conceptually, appears to be generally well regarded, but in reality is proving difficult to fully adopt. This difficulty is down to a combination of necessity in maintaining a legacy system, lack of senior management buy-in, managerial structure and resistance. Additionally, we are finding evidence of job crafting, especially with the software developers. Taken together, we put forward the argument that DevOps is an interdisciplinary topic which would greatly benefit from further management and potentially psychology oriented research attention
DevOps in Practice -- A preliminary Analysis of two Multinational Companies
DevOps is a cultural movement that aims the collaboration of all the
stakeholders involved in the development, deployment and operation of soft-ware
to deliver a quality product or service in the shortest possible time. DevOps
is relatively recent, and companies have developed their DevOps prac-tices
largely from scratch. Our research aims to conduct an analysis on practic-ing
DevOps in +20 software-intensive companies to provide patterns of DevOps
practices and identify their benefits and barriers. This paper presents the
preliminary analysis of an exploratory case study based on the interviews to
relevant stakeholders of two (multinational) companies. The results show the
benefits (software delivery performance) and barriers that these companies are
dealing with, as well as DevOps team topology they approached during their
DevOps transformation. This study aims to help practitioners and researchers to
better understand DevOps transformations and the contexts where the practices
worked. This, hopefully, will contribute to strengthening the evidence
regarding DevOps and supporting practitioners in making better informed
decisions about the return of investment when adopting DevOps.Comment: 8 pages, 1 figure, 2 tables, conferenc
Size Matters: Microservices Research and Applications
In this chapter we offer an overview of microservices providing the
introductory information that a reader should know before continuing reading
this book. We introduce the idea of microservices and we discuss some of the
current research challenges and real-life software applications where the
microservice paradigm play a key role. We have identified a set of areas where
both researcher and developer can propose new ideas and technical solutions.Comment: arXiv admin note: text overlap with arXiv:1706.0735
Migrating to Cloud-Native Architectures Using Microservices: An Experience Report
Migration to the cloud has been a popular topic in industry and academia in
recent years. Despite many benefits that the cloud presents, such as high
availability and scalability, most of the on-premise application architectures
are not ready to fully exploit the benefits of this environment, and adapting
them to this environment is a non-trivial task. Microservices have appeared
recently as novel architectural styles that are native to the cloud. These
cloud-native architectures can facilitate migrating on-premise architectures to
fully benefit from the cloud environments because non-functional attributes,
like scalability, are inherent in this style. The existing approaches on cloud
migration does not mostly consider cloud-native architectures as their
first-class citizens. As a result, the final product may not meet its primary
drivers for migration. In this paper, we intend to report our experience and
lessons learned in an ongoing project on migrating a monolithic on-premise
software architecture to microservices. We concluded that microservices is not
a one-fit-all solution as it introduces new complexities to the system, and
many factors, such as distribution complexities, should be considered before
adopting this style. However, if adopted in a context that needs high
flexibility in terms of scalability and availability, it can deliver its
promised benefits
Integrating DevOps with Existing Healthcare IT Infrastructure and Processes: Challenges and Key Considerations
The DevOps is a set of practices and tools that aim to improve the collaboration, communication, and collaboration between software development and IT operations teams. In healthcare systems, DevOps has the potential to improve the performance, reliability, and scalability of IT systems while ensuring regulatory compliance and the protection of sensitive patient data. However, integrating DevOps with existing healthcare IT infrastructure and processes can present several challenges, including resistance to change, compliance and regulatory requirements, integration with legacy systems, lack of resources, and skill shortages. To overcome these challenges, healthcare organizations need to consider a number of key considerations when integrating DevOps with their existing IT infrastructure and processes. These include a clear understanding of the existing IT infrastructure and processes, engagement with stakeholders, a phased approach, automation where possible, a culture of continuous improvement, ensuring security and compliance, and fostering collaboration and communication. By following these key considerations, healthcare organizations can successfully integrate DevOps with their existing IT infrastructure and processes, unlocking the full benefits of DevOps for their healthcare systems. These benefits include improved performance, reliability, and scalability, increased collaboration and communication between IT and clinical teams, and increased efficiency and cost savings. DevOps has the potential to revolutionize healthcare IT by delivering more flexible, reliable, and scalable systems that support the delivery of better patient care. By adopting DevOps, healthcare organizations can transform their IT operations and processes, ensuring that they are well-equipped to meet the changing needs of the healthcare industry
Report from GI-Dagstuhl Seminar 16394: Software Performance Engineering in the DevOps World
This report documents the program and the outcomes of GI-Dagstuhl Seminar
16394 "Software Performance Engineering in the DevOps World".
The seminar addressed the problem of performance-aware DevOps. Both, DevOps
and performance engineering have been growing trends over the past one to two
years, in no small part due to the rise in importance of identifying
performance anomalies in the operations (Ops) of cloud and big data systems and
feeding these back to the development (Dev). However, so far, the research
community has treated software engineering, performance engineering, and cloud
computing mostly as individual research areas. We aimed to identify
cross-community collaboration, and to set the path for long-lasting
collaborations towards performance-aware DevOps.
The main goal of the seminar was to bring together young researchers (PhD
students in a later stage of their PhD, as well as PostDocs or Junior
Professors) in the areas of (i) software engineering, (ii) performance
engineering, and (iii) cloud computing and big data to present their current
research projects, to exchange experience and expertise, to discuss research
challenges, and to develop ideas for future collaborations
HPC Cloud for Scientific and Business Applications: Taxonomy, Vision, and Research Challenges
High Performance Computing (HPC) clouds are becoming an alternative to
on-premise clusters for executing scientific applications and business
analytics services. Most research efforts in HPC cloud aim to understand the
cost-benefit of moving resource-intensive applications from on-premise
environments to public cloud platforms. Industry trends show hybrid
environments are the natural path to get the best of the on-premise and cloud
resources---steady (and sensitive) workloads can run on on-premise resources
and peak demand can leverage remote resources in a pay-as-you-go manner.
Nevertheless, there are plenty of questions to be answered in HPC cloud, which
range from how to extract the best performance of an unknown underlying
platform to what services are essential to make its usage easier. Moreover, the
discussion on the right pricing and contractual models to fit small and large
users is relevant for the sustainability of HPC clouds. This paper brings a
survey and taxonomy of efforts in HPC cloud and a vision on what we believe is
ahead of us, including a set of research challenges that, once tackled, can
help advance businesses and scientific discoveries. This becomes particularly
relevant due to the fast increasing wave of new HPC applications coming from
big data and artificial intelligence.Comment: 29 pages, 5 figures, Published in ACM Computing Surveys (CSUR
