To meet rising expectations (scalability, robustness, flexibility,...) these systems increasingly espouse complex distributed architectures, that are hard to design, deploy and maintain. To grasp this complexity, developers should be allowed to assemble large distributed systems from smaller parts using a seamless, high-level programming paradigm. We present such an assembly-based programming framework, enabling developers to easily define and realize complex distributed topologies as a construction of simpler blocks (e.g. rings, grids). It does so by harnessing the power of self-organizing overlays, that is made accessible to developers through a high-level Domain Specific Language and self-stabilizing runtime. Our evaluation further shows that our approach is generic, expressive, low-overhead and robust.","PeriodicalId":311948,"journal":{"name":"Proceedings of the Doctoral Symposium of the 17th International Middleware Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132880174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More recently, container orchestration systems provide a platform for container deployment and management of cluster resources. Software-as-a-Service (SaaS) providers traditionally make use of middleware to facilitate multi-tenancy in a federated cloud. Container orchestration presents many opportunities in achieving scalability and providing cost-efficient multi-tenancy. In this paper, we outline opportunities and challenges for multi-cloud deployment of containerized SaaS applications.","PeriodicalId":311948,"journal":{"name":"Proceedings of the Doctoral Symposium of the 17th International Middleware Conference","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133778033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AdaptCache is an adaptive caching middleware for application servers that monitors the current workload and generates policies to distribute and/or replicate objects and requests among the local caches of application servers so that most requests can be executed on locally cached objects and, at the same time, the load will be evenly distributed among servers. The project is divided into two main phases. The first one, which is described in detail in this paper, tackles the problem of dynamically distributing objects and requests for volatile and fluctuating e-commerce applications. Several data distribution approaches based on graph partitioning are proposed. The approaches are compared using the YCSB and RUBiS benchmarks showing that AdaptCache is able to dynamically capture various workload changes and react quickly to these changes. The second phase of the AdaptCache project explores data replication for distributed object caches. It discusses the advantages of object replication such as increased locality but also possible overheads due to consistency requirements and space limitations. Any dynamic replication solution must take these issues into account.","PeriodicalId":311948,"journal":{"name":"Proceedings of the Doctoral Symposium of the 17th International Middleware Conference","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123083568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Python gives the programmer high-productivity, but even with NumPy it is often not high-performant because of the GIL1, which makes it inherently single threaded. Bohrium intercepts NumPy calls and generates an intermediate language, Bohrium byte-code, before being compiled to OpenCL kernels. It thus grants Python/NumPy the ability to be easily run on multicore systems or GPUs, without changing the source code. The Bohrium byte-code can be optimized, by transforming byte-code sequences into more performant ones. This way, the scientific programmer will not need to change her code to utilize special performant constructs.","PeriodicalId":311948,"journal":{"name":"Proceedings of the Doctoral Symposium of the 17th International Middleware Conference","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116543934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We first propose a self-stabilizing virtual synchrony service realizing state machine replication in a setting with a fixed set of processors. We then develop a multipurpose reconfiguration service and suggest how the virtual synchrony service can be deployed in settings with more dynamic processor sets. This currently provides the theoretical basis to move into prototyping and evaluation, and can possibly lead to self-stabilizing versions of important services like Chubby, Zookeeper and Vsync.","PeriodicalId":311948,"journal":{"name":"Proceedings of the Doctoral Symposium of the 17th International Middleware Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115845539","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
