Based on a typology of crises and on case studies, we examine communication challenges and societal dynamics in conjunction with interactions among new media, officials and first responders, and the public. A number of technology issues associated with new media applications, such as their vast size, fast updates and semantic richness--albeit at semi-structured representations--are considered. Finally, we refer to features of the relationship between social media and the wider public, the associated ethics, risks and benefits and the potential role of citizens as first responders/volunteers, social activists and journalists/reporters.","PeriodicalId":385442,"journal":{"name":"International Conference on Utility and Cloud Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121148758","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}

This scenario is due to the current demand for flexible and adaptive solutions to deal with increasingly volatile operating environments. However, microservices do not solve the entire problem on their own. To provide the required levels of flexibility and adaptation demanded by modern systems, a set of technologies have to be jointly used. Technologies such as containers, auto-scalers, load balancers, cache applications and API gateways are commonly seen as part of microservice’s ecosystem. We argue that managing all these composing elements of this ecosystem is becoming too complicated and that we need autonomous solutions to manage and adapt these elements, including the microservice itself. Therefore, we propose the concept of Emergent Microservice and Emergent Ecosystems. These concepts consist of adding autonomic loops in each participating element, making them able to evolve their behaviour to support runtime and autonomous system adaptation. Further to that, these concepts make microservice-based systems capable of dealing with the increasing changes in the systems’ operating environment.","PeriodicalId":385442,"journal":{"name":"International Conference on Utility and Cloud Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115652900","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}

Owing to that, an urgent call on greening the computing and communications technologies is rising, especially on service hosts (data centers). However, researches are undertaken toward reduce the power consumption in data centers, these works are following different approaches to achieve different power optimization goals such as cost and performance. For example, approaches are following thermal control concepts while others following resources sharing. These approaches leak of the concept of the co-existing of quality assurance and green energy suppliers. In this paper, we proposed a green extended autonomy feedback control for data centers. In addition, we proposed a hybrid policy approach to engage co-exists of the two determinants in system autonomy. Our solution was test on a web-based application and proof (compared to autonomic-only systems) that it captures the co-existing and adapts the data center operation accordingly.","PeriodicalId":385442,"journal":{"name":"International Conference on Utility and Cloud Computing","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130716598","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}
