It is common to see applications using a combination of memory, local disk, and archival storage tiers within a single data center to meet their needs. For example, hot data can be kept in memory using ElastiCache, and colder data in cheaper, slower storage such as S3, using Amazon as an example. For user-facing applications, a recent trend is to exploit multiple data centers for data placement to enable better latency of access from users to their data. The conventional wisdom is that co-location of computation and storage within the same data center is a key to application performance, so that applications running within a data center are often still limited to access local data. In this paper, using experiments on Amazon, Microsoft, and Google clouds, we show that this assumption is false, and that accessing data in nearby data centers may be faster than local access at different or even same points in the storage hierarchy. This can lead to not only better performance, but also reduced cost, simpler consistency policies and reconsidering data locality in multiple DCs environment. This argues for an expansion of cloud storage tiers to consider non-local storage options, and has interesting implications for the design of a distributed storage system.","PeriodicalId":283088,"journal":{"name":"Proceedings of the 2nd International Workshop on Software-Defined Ecosystems","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133309923","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}

The advent of Cloud Computing has not only lowered the cost of IT operations but also enabled the notion of continuous delivery, which promises to radically reduce frictions in DevOps processes and speed up the product delivery cycle. With increased demand on functionality and feature, we have also seen these applications becoming more sophisticated, often integrating multiple modern programming models and techniques with the traditional n-tier web application into a composite application. This paper proposes an architectural blueprint for improved continuous delivery of these complex composite applications. It treats a solution as a holistic entity comprised of application logic and software-defined environment that the logic relies on. It also proposes a collaborative approach to software-defined Platform-as-a-Service environment building. This being an ongoing research project, this paper also briefly describes prototype, work-in-progress and thoughts on future directions.","PeriodicalId":283088,"journal":{"name":"Proceedings of the 2nd International Workshop on Software-Defined Ecosystems","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121312591","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}

XOS raises the level of abstraction in an IaaS cloud architecture by elevating scalable software services to first-class objects. This involves adopting three design principles: (1) Everything-as-a-Service (XaaS) (services are building blocks, and combinations of those building blocks are also services); (2) Multi-tenancy (a tenant relationship links one service to another, and facilitates reasoning about safety, privacy and efficiency); and (3) Control/Data-plane separation (services are configured through a logically centralized service controller interface, but the controller is not on the data path between services). XOS applies these principles through the lens of an operating system - it defines a set of abstractions that support constructing multi-tenant services that can be folded back into XOS as available building blocks, while also extending the capabilities of conventional IaaS. The paper shows how these abstractions can be used to build a functional, evolvable, service-oriented cloud.","PeriodicalId":283088,"journal":{"name":"Proceedings of the 2nd International Workshop on Software-Defined Ecosystems","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115196105","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}

While data center hosts multiple VDCs and network fabrics are managed as a single logical network entity, the network is practically unable to prevent a traffic flood in one VDC from affecting the other VDCs around it. Hence, the data center's network fabric becomes a focal point. Tailoring network to implement virtual fabrics to give each VDC the illusion that all the resources assigned to it are dedicated and isolated, just as if each VDC was connected by a separate physical network, is challenging. Realizing this vision concretely translates into building a network fabric that is virtualized, isolated and that prevents packet forwarding degradation. One of the significant challenges is then around resource constraints. In this paper we present a decentralized control for vFabrics based on a three-level control strategy that dynamically adjusts resource allocation over different time scales to fit vFabrics needs in terms of packet processing. Results show that control strategy guarantees a high fairness level among vFabrics, preserves high performance packet processing by maintaining processing latency stability, and optimizes resource utilisation.","PeriodicalId":283088,"journal":{"name":"Proceedings of the 2nd International Workshop on Software-Defined Ecosystems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127050380","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}

However, traditional High Performance Computing (HPC) based federation models can be restrictive as they present users with a pre-defined set of resources and do not allow federations to evolve in response to changing resources or application needs. As emerging application workflows and the underlying resources become increasingly dynamic and exhibit changing requirements and constraints, they cannot be easily supported by such federation models. Instead, new federation models that are capable of dynamically adapting to these emerging needs are required. In this paper, we present a programmable dynamic federation model that uses software-defined environment concepts to drive the federation process and seamlessly adapt resource compositions at runtime. The resulting software-defined federation adapts to meet both requirements and constraints set by the user, application, and/or resource providers. In this paper we present the design and prototype implementation of such software-defined federation model, and demonstrate its operation and performance through a use case where heterogeneous, geographically distributed resources are federated based on user specifications, and the federation evolves over time following the requirements and constraints defined by the user.","PeriodicalId":283088,"journal":{"name":"Proceedings of the 2nd International Workshop on Software-Defined Ecosystems","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132034488","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}
