Trends in Development of Databases and Blockchain [article]

Mayank Raikwar, Danilo Gligoroski, Goran Velinov
2020 arXiv   pre-print
We explain how the CAP (Consistency, Availability, Partition tolerance) theorem known for databases influenced the DCS (Decentralization, Consistency, Scalability) theorem for the blockchain systems.  ...  By using an analogous relaxation approach as it was used for the proof of the CAP theorem, we postulate a "DCS-satisfiability conjecture."  ...  In more details, CAP theorem identifies the three specific system properties for any distributed/decentralized system.  ...

EDR: An energy-aware runtime load distribution system for data-intensive applications in the cloud

Bo Li, Shuaiwen Leon Song, Ivona Bezakova, Kirk W. Cameron
2013 2013 IEEE International Conference on Cluster Computing (CLUSTER)  
Data centers account for a growing percentage of US power consumption. Energy efficiency is now a first-class design constraint for the data centers that support cloud services.  ...  We demonstrate experimentally the cost differences in various replica selection scenarios and show that our novel approach is as fast as the best available decentralized approach DONAR,while additionally  ...  This is to simulate various power prices of data centers in different geographical locations; 2) the bandwidth cap for our SystemG Ethernet is approximately 100 MB/s; 3) we set the user-defined max tolerable  ...

My home is my post-office

Gregory Tsipenyuk, Jon Crowcroft
2017 Proceedings of the Second International Conference on Internet of things, Data and Cloud Computing - ICC '17  
We analyze a number of stores and synchronization implementations and compare them with the open source Dovecot email server.  ...  First, email's update from multiple devices has to be eventually reconciled with the server. Prioritization of updates is difficult and maybe undesirable.  ...  First, we are proposing a high level decentralized email architecture where the email history is stored on a cluster of user's owned devices.  ...

A SURVEY ON CLOUD STORAGE – IMPACT OF STORAGE ON THE PERFORMANCE

Prapti Panigrahi .
2018 International Journal of Research in Engineering and Technology  
The cloud computing model allows for pay-by-use and thus avoids usage of personal computers or local servers.  ...  It is implemented by a connected network of remote servers, accessed via the internet, for processing, storing and managing data.  ...  The key to fast recovery is utilizing the scale of the RAMCloud cluster.  ...

H2O: An Autonomic, Resource-Aware Distributed Database System [article]

Angus Macdonald, Alan Dearle, Graham Kirby
2010 arXiv   pre-print
Creating and maintaining highly-available, replicated database systems can be difficult for untrained users, and costly for IT departments.  ...  This paper discusses the requirements for such a system and presents the design and implementation of H2O.  ...  For instance, servers with near zero percent utilization still use around 50% of the power used at peak utilization.  ...

Hierarchical SLA-Driven Resource Management for Peak Power-Aware and Energy-Efficient Operation of a Cloud Datacenter

Hadi Goudarzi, Massoud Pedram
2016 IEEE Transactions on Cloud Computing  
In this work, a hierarchical, service level agreement (SLA) based resource management solution for cloud datacenters is presented, which considers the energy non-proportionality of existing servers, peak  ...  power constraints, and cooling power consumption.  ...  The results show a big difference between theoretical and practical peak power consumption of server clusters. This difference grows by increasing the size of the cluster.  ...

2020 Frontiers in Blockchain  
Therefore, this study proposes a new mode of governance based on the regulation of new power relationships between the state and actors in the digital domain.  ...  These developments call for effective governance to protect the basic interests and needs of these actors. Simultaneously, the very nature of governance is also changing.  ...  Of particular utility for decentralized network governance is the clustering coefficient.  ...
