Active Replication Fabric for Reliable IoT Database Management

Evaluate free trial softwareReview other key features

eXtremeDB Active Replication Fabric™ offers solutions for IoT system developers.

eXtremeDB with Active Replication Fabric offers reliable data management for IoT by solving 5 challenges for IoT system developers:

•   Bidirectional Replication
•   Intermittent connections
•   Multi-tier replication (e.g. edge-to-gateway-to-gateway-to-cloud)
•   Security
•   Compression to maximize limited bandwidth networks

Edge nodes’ physical connectivity can be intermittent, and constrained. Some popular protocols have limited bandwidth (ZigBee, NFC and RFID, LPWAN, Bluetooth Low Energy, etc.).   Edge device connectivity can be intermittent because of the physical device location (e.g. a mobile device,) or because the device is battery operated and connects at certain predefined times. From the standpoint of data management, the unpredictable connectivity means that fully integrated support for “push” and “pull” protocols is important to preserve data collected at the edge.

We use the term “storage containers” for databases maintained on edge devices that are mapped to an upstream database.

The eXtremeDB Active Replication Fabric APIs allow device-based applications to collect data, then transmit the collected data when connected.  Likewise, they also allow replicating server-side data to IoT devices, usually for new device configuration and provisioning.  Data flow is fully automated through the Active Replication Fabric.  The APIs provide automatic or on-demand data exchange between collection points and servers.


Security Features

eXtremeDB security features include Secure Sockets Layer (SSL) connections, a standard security technology that creates an encrypted link between two endpoints.  AES encryption is included to secure data at rest, and Cyclic Redundancy Check (CRC) on the database page level to detect unauthorized modifications.  Learn more.


Data Compression

Run-length encoding (RLE) compression can be applied to columnar data (i.e. fields defined as the ‘sequence’ data type).  McObject tests show that activating this feature reduced storage space requirements by 75% and increased speed in reading the database by 21%.  eXtremeDB also includes a feature for compressing non-columnar data.  Read about this and other key features.

Active Replication fabric means reliable database management for IoT and support on all platforms from edge to cloud.  Learn more.
