Serverless End Game: Disaggregation enabling Transparency [article]

Pedro García-López, Aleksander Slominski, Simon Shillaker, Michael Behrendt, Barnard Metzler
2020 arXiv   pre-print
For many years, the distributed systems community has struggled to smooth the transition from local to remote computing. Transparency means concealing the complexities of distributed programming like remote locations, failures or scaling. For us, full transparency implies that we can compile, debug and run unmodified single-machine code over effectively unlimited compute, storage, and memory resources. We elaborate in this article why resource disaggregation in serverless computing is the
more » ... puting is the definitive catalyst to enable full transparency in the Cloud. We demonstrate with two experiments that we can achieve transparency today over disaggregated serverless resources and obtain comparable performance to local executions. We also show that locality cannot be neglected for many problems and we present five open research challenges: granular middleware and locality, memory disaggregation, virtualization, elastic programming models, and optimized deployment. If full transparency is possible, who needs explicit use of middleware if you can treat remote entities as local ones? Can we close the curtains of distributed systems complexity for the majority of users?

Community Grids [chapter]

Geoffrey Fox, Ozgur Balsoy, Shrideep Pallickara, Ahmet Uyar, Dennis Gannon, Aleksander Slominski
2002 Lecture Notes in Computer Science  
We describe Community Grids built around Integration of technologies from the peer-to-peer and Grid fields. We focus on the implications of Web Service ideas built around powerful event services using uniform XML interfaces. We go through collaborative systems in detail showing how one can build an environment that can use either P2P approaches like JXTA or more conventional client-server models.

On the Future of Cloud Engineering [article]

David Bermbach, Abhishek Chandra, Chandra Krintz, Aniruddha Gokhale, Aleksander Slominski, Lauritz Thamsen, Everton Cavalcante, Tian Guo, Ivona Brandic, Rich Wolski
2021 arXiv   pre-print
Ever since the commercial offerings of the Cloud started appearing in 2006, the landscape of cloud computing has been undergoing remarkable changes with the emergence of many different types of service offerings, developer productivity enhancement tools, and new application classes as well as the manifestation of cloud functionality closer to the user at the edge. The notion of utility computing, however, has remained constant throughout its evolution, which means that cloud users always seek

On the other hand, cloud providers try to maximize their profits while assuring service-level objectives of the cloud-hosted applications and keeping operational costs low. All these outcomes require systematic and sound cloud engineering principles. The aim of this paper is to highlight the importance of cloud engineering, survey the landscape of best practices in cloud engineering and its evolution, discuss many of the existing cloud engineering advances, and identify both the inherent technical challenges and research opportunities for the future of cloud computing in general and cloud engineering in particular.

Serving deep learning models in a serverless platform [article]

Vatche Ishakian, Vinod Muthusamy, Aleksander Slominski
2018 arXiv   pre-print
Serverless computing has emerged as a compelling paradigm for the development and deployment of a wide range of event based cloud applications. At the same time, cloud providers and enterprise companies are heavily adopting machine learning and Artificial Intelligence to either differentiate themselves, or provide their customers with value added services. In this work we evaluate the suitability of a serverless computing environment for the inferencing of large neural network models. Our

Our experimental results show that while the inferencing latency can be within an acceptable range, longer delays due to cold starts can skew the latency distribution and hence risk violating more stringent SLAs.

SUMMARIZED: Efficient Framework for Analyzing Multidimensional Process Traces under Edit-distance Constraint [article]

Phuong Nguyen and Vatche Ishakian and Vinod Muthusamy and Aleksander Slominski
2019 arXiv   pre-print
Domains such as scientific workflows and business processes exhibit data models with complex relationships between objects. This relationship is typically represented as sequences, where each data item is annotated with multi-dimensional attributes. There is a need to analyze this data for operational insights. For example, in business processes, users are interested in clustering process traces into smaller subsets to discover less complex process models. This requires expensive computation of

Related work on dimension reduction and embedding methods do not take into account the multi-dimensional attributes of data, and do not address the interpretability of data in the embedding space (i.e., by favoring vector-based representation). In this work, we introduce Summarized, a framework for efficient analysis on sequence-based multi-dimensional data using intuitive and user-controlled summarizations. We introduce summarization schemes that provide tunable trade-offs between the quality and efficiency of analysis tasks and derive an error model for summary-based similarity under an edit-distance constraint. Evaluations using real-world datasets show the effectives of our framework.

Opportunities in Software Engineering Research for Web API Consumption [article]

Erik Wittern, Annie Ying, Yunhui Zheng, Jim A. Laredo, Julian Dolby, Christopher C. Young, Aleksander A. Slominski
2017 arXiv   pre-print
Nowadays, invoking third party code increasingly involves calling web services via their web APIs, as opposed to the more traditional scenario of downloading a library and invoking the library's API. However, there are also new challenges for developers calling these web APIs. In this paper, we highlight a broad set of these challenges and argue for resulting opportunities for software engineering research to support developers in consuming web APIs. We outline two specific research threads in

Furthermore, we present new work on how we combine (1) and (2) to provide IDE support for application developers consuming web APIs. As web APIs are used broadly, research in supporting the consumption of web APIs offers exciting opportunities.

On Building Parallel & Grid Applications: Component Technology and Distributed Services

Dennis Gannon, Sriram Krishnan, Liang Fang, Gopi Kandaswamy, Yogesh Simmhan, Aleksander Slominski
2005 Cluster Computing  
Software Component Frameworks are well known in the commercial business application world and now this technology is being explored with great interest as a way to build large-scale scientific application on parallel computers. In the case of Grid systems, the current architectural model is based on the emerging web services framework. In this paper we describe progress that has been made on the Common Component Architecture model (CCA) and discuss its success and limitations when applied to
more » ... when applied to problems in Grid computing. Our primary conclusion is that a component model fits very well with a services-oriented Grid, but the model of composition must allow for a very dynamic (both in space and it time) control of composition. We note that this adds a new dimension to conventional service workflow and it extends the "Inversion of Control" aspects of must component systems.

2008 Lecture Notes in Computer Science  
Today's enterprise applications span multiple systems and organizations, integrating legacy and newly developed software components to deliver value to business operations. Often business processes rely on human activities that may not be predicted in advance, and information exchange is heavily based on e-mails or attachments where the content is unstructured and needs discovery. Visibility of such end-to-end operations is required to manage compliance and business performance. Hence, it

Hence, it becomes necessary to develop techniques for tracking and correlating the relevant aspects of business operations as needed without the cost and overhead of a fully fledged data and process reengineering. Our business provenance solution provides a generic data model and middleware infrastructure to collect and correlate information about how data was produced, what resources were involved and which tasks were executed. Business provenance gives the flexibility to selectively capture information required to address a specific compliance or performance goal. Additionally, a powerful correlation mechanism yields a representation of the end-to-end operation that puts each business artifact into the right context, for example, to detect situations of compliance violations and find their root causes.

Web 2.0 promises a more enjoyable experience for creating content by users by providing easy-to-use information sharing and collaboration tools, and focusing on user-centered design. Provenance in Scientific Workflow Management is one kind of user-generated data that can benefit from using Web 2.0. We propose a simple set of Web 2.0 technologies that is simple to implement and can be immediately leveraged by scientific users. Using Atom Syndication Protocol to represent workflow state and its

Collaboration and authoring can be facilitated by using Atom Publishing Protocol and standard Web 2.0 blogging tools to publish and annotate provenance. Users can search stored provenance by using search engines. If search results are in standard Atom Syndication Protocol, for example when search engines support OpenSearch standard, then Atom feeds can be used to monitor provenance changes increasing the likelihood of discoveries. By using those Web 2.0 standards, the value of scientific provenance data increases by making it a natural part of growing a variety of user-generated scientific (and non-scientific) content.
