Enginio Data Storage (EDS)
Flexible and powerful
cloud data storage
with built-in user and
data access control

EDS Use Cases
• Content storage, sharing and
synchronization
• User profiles and access
control
• Remote monitoring and control
• Usage Statistics
• Client-to-Client
Communications
• Application settings
• N-screen; Embedded, Web,
Desktop, Mobiles…

How to Use with Qt?

"
EnginioClient
*client
=
new
EnginioClient;
client-‐>setBackendId(backendId);
"
QJsonObject
object;
object["objectType"]
=
QString::fromUtf8("objects.movies");
object["name"]
=
QString::fromUtf8("The
Matrix");
object["year"]
=
1999;
//
Send
the
request
EnginioReply
*reply
=
client-‐>create(object);

Managed WebSocket (MWS)
Fully managed
service implementing
a bi-directional, real-time
communication
gateway for
WebSockets.

Where to use?
• Chat applications
• Social feeds
• Multiplayer games
• Collaborative editing
• Sport updates
• Location based apps
• Your killer app

{
var
data
=

}
}
}
doc.send()
}

Managed Application Runtime (MAR)
Scalable,"
Multi-language,"
Multi-database,"
Application Platform as a Service

MAR Use Cases
Internet of Things & Embedded!
• Cloud compute, analyze, metrics and data
visualization
• Remote management, APIs and configuration of
”things”
"
Websites!
• High-traffic campaign & marketing sites
• Education, Gaming, Personal…
"
Customer facing applications!
• Online Applications
• API’s for web, desktop & mobile

With PaaS, developer can focus just on building great apps. No need to worry about
servers, operating system, loadbalancing, network or infrastructure.

Managed Application Runtimes
How does it work?

Supported Frameworks
Supported frameworks by 3rd party build packs
Scala, Clojure, Play, Gradle, Grails, PHP, Go, Meteorite, Perl, Dart, Nginx, Apache, Jekyll

Built-in Services
or choose from our cloud based services
Enginio Data Storage"
Managed WebSocket
or choose anything with SDK
... Amazon, Azure, Google ...

Developer Friendly
Deployment
