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

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
