Active Replication Fabric Offers Reliable IoT Database Management
Small footprint eXtremeDB offers reliability solutions for IoT developers.
eXtremeDB Active Replication Fabric™ offers solutions for IoT system developers.
Active Replication Fabric offers reliable data management for IoT by solving 5 challenges for 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; a common task 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
Billions of IoT devices’ and their storage containers are exposed and inherently vulnerable. Unlike servers, IoT edge devices run in the open and don’t enjoy IT staff attendance, sophisticated firewalls and other security apparatus available at the back-end.
Cyclic Redundancy Check (CRC) on the database page level detects any unauthorized modification to stored data
AES encryption employs a user-provided cipher to prevent access or tampering
Multi-tier Network Topology and Network Discovery
eXtremeDB’s Active Replication Fabric supports complex IoT network topology; edge devices connect to gateways, gateways connect to other gateways closer to the cloud, which ultimately connect to servers in the cloud which may themselves consist of many shards/nodes. Further, any eXtremeDB instance in this topology might also be a member of a high availability group or an eXtremeDB Cluster. eXtremeDB’s xPanel dashboard includes a visual network discovery tool that greatly simplifies managing, monitoring and leveraging eXtremeDB’s tracing capability.

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 improved the speed of reading the database by 21%. eXtremeDB also includes a feature for compressing non-columnar data.
eXtremeDB also offers low-level network compression. IoT networks often use low-bandwidth networks which requires network traffic to be compressed. eXtremeDB implements compression at its System Abstraction Layer (SAL), meaning that compression can be applied to any supported socket type (plain TCP, SSL, local-domain, UDP and others).

White paper: Distributed Database Systems and Edge/Fog/Cloud Computing
A distributed database system is one in which the data belonging to a single logical database is distributed to two or more physical databases. Beyond that simple definition, there are a confusing number of possibilities for when, how, and why the data is distributed. Some are applicable to edge and/or fog computing, some others are applicable to fog and/or cloud computing, and some are applicable across the entire spectrum of edge, fog and cloud computing.
White paper: Will the Real IMDS Please Stand Up?
In-memory database systems (IMDSs) have changed the software landscape, enabling “smarter” embedded applications and sparking mergers and acquisitions involving the largest technology companies. But IMDSs’ popularity has sparked a flurry of products falsely claiming to be in-memory database systems. Understanding the distinction is critical to determining the performance, cost and ultimately the success or failure of a solution. This white paper examines specific products, seeking to answer the question, “is it really an in-memory database system?”
