Support for autonomic scaling of multi-tier service oriented applications requires determination of when, what, and where to scale. \"When\" is addressed by hotspot detection schemes using techniques including performance modeling and time series analysis. \"What\" relates to determining the quantity and size of new resources to provision. \"Where\" involves identification of the best location(s) to provision new resources. In this paper we investigate primarily \"where\" new infrastructure should be provisioned, and secondly \"what\" the infrastructure should be. Dynamic scaling of infrastructure for service oriented applications requires rapid response to changes in demand to meet application quality-of-service requirements. We investigate the performance and resource cost implications of VM placement when dynamically scaling server infrastructure of service oriented applications. We evaluate dynamic scaling in the context of providing modeling-as-a-service for two environmental science models.","PeriodicalId":273902,"journal":{"name":"2014 IEEE International Conference on Cloud Engineering","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132926169","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}

Feillet","doi":"10.1109/IC2E.2014.68","DOIUrl":"https://doi.org/10.1109/IC2E.2014.68","url":null,"abstract":"Cloud offers numerous technical middleware services such as databases, caches, messaging systems, and storage but very few business middleware services as first tier managed services. Business middleware such as business process management, business rules, operational decision management, content management and business analytics, if deployed in a cloud environment, is typically only available in a hosted (black-box) model. This is partly due to where cloud is in its evolution, and mostly due to the relatively higher complexity of business middleware vs. technical middleware in the deployment, provisioning, usage, etc. Business middleware consists of multiple functions for business processes design and modeling, execution, optimization, monitoring, and analysis. These functions and their associated complexity have inhibited the wholesale migration of existing business middleware to the cloud. To better understand the complexity in bringing business middleware to the cloud and to develop a systematic cloud enablement approach, we studied the deployment of IBM's Operational Decision Manager (ODM) business middleware product as a managed service (Cloud Decision Service) in IBM's BlueMix cloud platform. Our study indicates that complex middleware must be componentized along functional boundaries, and provide these functions for different business users and developers with cloud experience. In addition, middleware services must leverage other cloud services and they should provide interfaces so that they can be consumed by Java applications as well as by polyglot applications (JavaScript, Ruby, Python, etc). Applications can bind to and use our Cloud Decision Service in a matter of seconds. In contrast, it takes hours to days to setup such a service in the traditional packaged software model. Based on the lessons learned from this experiment we develop a blueprint for enabling high value business middleware as managed cloud services.","PeriodicalId":273902,"journal":{"name":"2014 IEEE International Conference on Cloud Engineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126950108","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}

A widely recognized impediment to achieving this goal is so called \"Virtual Machines sprawl\", a phenomenon referring to the situation when customers order Virtual Machines (VM) on the cloud, use them extensively and then leave them inactive for prolonged periods of time. Since a typical cloud provisioning system treats new VM provision requests according to the nominal virtual hardware specification, an often occurring situation is that the nominal resources of a cloud/pool become exhausted fast while the physical hosts utilization remains low.We present a novel cloud resources scheduler called Pulsar that extends OpenStack Nova Filter Scheduler. The key design principle of Pulsar is adaptivity. It recognises that effective safely attainable over-commit ratio varies with time due to workloads' variability and dynamically adapts the effective over-commit ratio to these changes. We evaluate Pulsar via extensive simulations and demonstrate its performance on the actual OpenStack based testbed running popular workloads.","PeriodicalId":273902,"journal":{"name":"2014 IEEE International Conference on Cloud Engineering","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124509549","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}
