Eurotech’s Everyware™ Cloud provides a “Device as a Service”
architecture for connecting data-gathering devices to your business
infrastructure.
The Cloud architecture of Collect, Communicate, Store, and
Act puts you in control of your devices in the field:
Here are definitions of the Everyware Cloud terms you will
see throughout this manual:
Sensors & Devices
A wide variety of sensors and
devices are in use across the industry. Often, these devices contain
important data that is needed by business applications for real-time business
decisions, data aggregation, or statistical modeling; but such actions are
hindered by the lack of an easy connection between devices and applications.
The Everyware Cloud provides the needed connection for data gathering and
distribution.

M2M
Gateways
Eurotech provides a number of
robust hardware platforms, including DuraCor, DuraNav, and Helios.
These platforms provide a gateway between the device-level components and the
Cloud, and form the “Device” portion of the Everyware Device Cloud (EDC).

MQTT
Protocol
The Everyware Cloud is designed
to use a publish-subscribe message brokering protocol known as MQTT. MQTT is
an open standard transport layer, which uses a hierarchical topic namespace
and a flexible data payload. MQTT is bandwidth efficient and simple to
implement, providing both security and reliability of transport and a
decoupling of data producers from application consumers, in a one-to-many
message distribution. Eurotech’s Everyware Software Framework (ESF) includes
MQTT as a standard data communication feature.

Broker
The core technology of
Everyware Cloud is the message broker. The broker runs in the Cloud and
provides an MQTT server into which devices publish their data. MQTT clients
may also issue subscriptions for certain topic namespace definitions. When a
data payload is published into the Cloud on a certain topic, the payload is redistributed
to connected clients subscribed to that topic.
|
|
Rule
Engine
The Everyware Cloud uses a
SQL-based rules engine to process incoming published data, allowing immediate
message processing and/or notifications to occur based on user-defined
criteria. Statistical rules are applied over the data in real-time. The
actions generated by a rule can include e-mail, SMS, or Twitter notification,
an MQTT publish event, or a REST API call.
|
|
Data Store
The Everyware Cloud utilizes a
non-SQL database for device data storage. The data is redundant and
replicated across geographical regions for maximum reliability. Device/user
and data plan details are stored in a separate replicated, redundant SQL
database.
|
|
APIs
REST APIs provide easy,
programmatic access to request or store data from the storage databases and
to all the other features of the Cloud platform. The APIs allow you to incorporate
the data into another system or to develop custom applications within your enterprise.
|
|
Console
The Everyware Cloud Console provides
a graphical user interface that shows all aspects of your account’s
operation. Your account administrator can manage users, devices, data, data
plans, and rules definitions through the console. Users can be given
permissions to view data, as needed.
|
|
Application
Business Logic
The Everyware Cloud is designed
to provide a “zero configuration” communication architecture, allowing you to
focus on developing business application components, without having to worry
about device-level programming or complicated data networks. It is a powerful
software framework, leveraging the power and redundancy of cloud computing,
open-standard protocols (MQTT, TCP/IP, REST), and strong security.
