Xamarin.iOS does full Ahead Of Time

(AOT) compilation to produce an ARM

binary for Apple’s App Store.

Xamarin.Android takes advantage of

Just In Time (JIT) compilation on the

Android device.

Backend code

REST API

- Client DB: SQLLite

- Azure SDK - MobileServiceClient

- Synchronization

- Hidden HTTP interactions

- Implementation with Interfaces – mockable

- Samples: iOS, Android, Xamarin, Cordova, Windows

Remote Monitoring Service Architecture

https://azure.microsoft.com/en-us/solutions/iot-suite/

Per-Device AuthenticationIndividual device identities and credentials

Connection MultiplexingSingle device-cloud connection for all communications

(device-to-cloud, cloud-to-device)

Multi-ProtocolNatively supports AMQPS, HTTPS, MQTT

Extensible protocol support for custom protocol needs

Multi-PlatformDevice SDKs available for multiple platforms

RTOS, Linux, Windows, iOS, Android

Service SDK supports multiple languages (Node, Java, C#)

- Security takes precedence over all other capabilities

- A device establishes all connections and routes in an outbound-onlyfashion.

- Devices should only connect to or establish routes to well-knownservices

- The communication path is secured at the application protocol layer

- Authorization and authentication are based on per-device identities. It makes access credentials instantly revocable.

- For a device to receive a command from the backend, the devicemust regularly initiate a connection to check for any pending commands to process.

Typy

Type Description

bigint Integers in the range -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807).

float Floating point numbers in the range - 1.79E+308 to -2.23E-308, 0, and 2.23E-308 to 1.79E+308.

nvarchar(max) Text values, comprised of Unicode characters. Note: A value other than max is not supported.

datetime Defines a date that is combined with a time of day with fractional seconds that is based on a 24-hour clock and relative to

UTC (time zone offset 0).

State is made highly-available through replication and distributed through partitioning
