Adapting Distributed Database Systems for High Availability

The availability offered by current data replication and update algorithms varies with dynamically changing conditions which include the network configuration and system load. With dynamic adaptability, systems can switch to an appropriate mechanism to improve perFormance and availability, In this paper, we present an algorithm to estimate the overall availability of transaction processing in a...

An Authorization Framework for Database Systems

Today, data plays an essential role in all levels of human life, from personal cell phones to medical, educational, military and government agencies. In such circumstances, the rate of cyber-attacks is also increasing. According to official reports, data breaches exposed 4.1 billion records in the first half of 2019. An information system consists of several components, which one of the most im...

HydraVM: Low-Cost, Transparent High Availability for Virtual Machines

Existing approaches to providing high availability (HA) for virtualized environments require a backup VM for every primary running VM. These approaches are expensive in memory because the backup VM requires the same amount of memory as the primary, even though it is normally passive. In this paper, we propose a storage-based, memory-efficient HA solution for VMs, called HydraVM, that eliminates...

Analyzing Availability of Replicated Database Systems

Qualitative studies have shown that replication control methods vary in the availability and performance of distributed database processing. Quantitative evaluation of these methods, however, requires a general availability model and experimental performance data. In this paper. we define and study aLgorithmic and operationaL availabilities of distributed database systems that employ replicatio...

Fast and Transparent Database Reconfiguration for Scaling and Availability through Dynamic Multiversioning

In this paper, we study replication techniques for scaling and continuous operation for a dynamic content server. Our focus is on supporting transparent and fast reconfiguration of its database tier in case of overload or failures. We show that the data persistence aspects can be decoupled from reconfiguration of the database CPU. A lightweight in-memory middleware tier captures the typically h...
