We present Albatross, a technique for live migration in a multitenant database serving OLTP style workloads where the persistent database image is stored in a network attached storage.  ...  However, existing databases-relational databases and Key-Value stores alike-lack low cost live migration techniques, thus resulting in heavy performance impact during elastic scaling.  ...  Acknowledgments The authors would like to thank Philip Bernstein, Pamela Bhattacharya, Aaron Elmore, and the anonymous reviewers for providing useful feedback.  ...

Adaptive Distributed Load Balancing Algorithm Based on Live Migration of Virtual Machines in Cloud

Yi Zhao, Wenlong Huang
2009 2009 Fifth International Joint Conference on INC, IMS and IDC  
 When deployed over a pay-per-use infrastructure, elastic scaling and load balancing, enabled by low cost live migration of tenant databases, is critical to tolerate load variations while minimizing operating  ...  ABSTRACT(Cont.)  To be effectively used for elasticity, database migration must be lightweight.  i.e. with minimal service interruption and negligible performance impact.  This snapshot is then copied  ...  successful live migration, the memory, storage, and network connectivity of the virtual machine  Albatross migrates the database cache and the state of active transactions to ensure minimal impact on  ...

ShuttleDB: Database-Aware Elasticity in the Cloud

Sean Kenneth Barker, Yun Chi, Hakan Hacigümüs, Prashant J. Shenoy, Emmanuel Cecchet
2014 IEEE International Conference on Autonomic Computing  
Motivated by the growing popularity of database-as-aservice clouds, this paper presents ShuttleDB, a holistic approach enabling flexible, automated elasticity of database tenants in the cloud.  ...  We first propose a database-aware live migration and replication method designed to work with off-the-shelf databases without any database engine modifications.  ...  To allow for shared-nothing live migration of virtual machines, we make use of the Storage XenMotion feature, which allows for moving disk, memory, and virtual devices to a remote host.  ...

DBaaS Multitenancy, Auto-tuning and SLA Maintenance in Cloud Environments: a Brief Survey

Vinicius Da Silveira Segalin, Carina Friedrich Dorneles, Mario Antonio Ribeiro Dantas
2018 iSys  
Among many types of services we have today, Database as a Service (DBaaS) is the one where a database is provided in the cloud in all its aspects.  ...  Examples of aspects related to DBaaS utilization are data storage, resources management and SLA maintenance.  ...  A technique for live migration in a multitenant database is thus presented, named Albatross [21] , where the database cache and state of active transactions are migrated to ensure minimal impact on transaction  ...

ChronoStream: Elastic stateful stream computation in the cloud

Yingjun Wu, Kian-Lee Tan
2015 2015 IEEE 31st International Conference on Data Engineering  
We introduce ChronoStream, a distributed system specifically designed for elastic stateful stream computation in the cloud.  ...  ChronoStream treats internal state as a first-class citizen and aims at providing flexible elastic support in both vertical and horizontal dimensions to cope with workload fluctuation and dynamic resource  ...  The authors would like to thank David Maier, Zhengping Qian, Zhou Zhao, and the anonymous reviewers for their insightful suggestions.  ...

2019 Proceedings of the VLDB Endowment  
In this paper, we present MgCrab, a live migration technique for a deterministic database system, that leverages the determinism to maintain the consistency of data on the source and destination nodes  ...  Live migration, which moves the specified data from a source machine to a destination node while continuously serving the incoming transactions, is a key technique required for the elasticity.  ...  In this paper, we present MgCrab, a technique for live migration in a shared-nothing distributed, deterministic database system.  ...

Exploiting the Social Structure of Online Media to Face Transient Heavy Workload

Ibrahima Gueye, Idrissa Sarr, Hubert Naacke
The second goal is to combine an elastic approach with a load balancing process to sustain the overall performances while minimizing the required resources.  ...  Such a situation is generally due to the simultaneous access of several users to a small piece of data owned by a user or a few ones.  ...  To this end, we are experimenting on top of Amazon EC2 cloud, using Oracle KVLite [31] for data storage and access at each DB node.  ...
