Microsoft Azure Stack is an extension of Azurebringing the agility and innovation of cloud computing to your on-premises environment and enabling the only hybrid cloud that allows you to build and deploy hybrid applications anywhere. We bring together the best of the edge and cloud to deliver Azure services anywhere in your environment.

In addition to these, you will need to bear in mind your IoT solution specifics considering device constrains and communication limitations. What should your retry and buffering logic be to save battery and limit bandwidth usage? How and where do you securely store device credentials? How will you provision devices at scale?

Documentation for various developing needs is available.Azure IoT Development Centerprovides a single landing page for anything developer, linking to resources such as training content, full API documentation, How-To guides. Thedeveloper guidepart of the Azure documentation provides how-to tutorials to help you get started with various IoT Hub features.GitHub repositoriescontains instructions on how to get started from source code and feature supported in the SDKs. A list of sample applications showing how to use various IoT Hub features are also provided. You can provide feedback on documentation via GitHub issues and comments directly on the online documentation.

Developers who prefer to use protocol libraries to develop custom solutions can use REST, AMQP and MQTT APIs exposed by IoT Hub. However, developers using these low-level protocols must deal with the intricacies of implementing complex device-to-cloud communication addition, the IoT industry is quickly evolving past simple scenarios. Essential features like device management, security and digital twin require manipulating interfaces with a higher level of abstraction. Relying on protocol libraries means you will need to reimplement those abstractions later.

Deliver high-quality video content anywhere, any time, and on any device

Depending on the IoT scenario and your developer experience, you may have a preferred language or platform. The SDKs got you covered. Broad language and platform support with protocol flexibility allows you to develop in your preferred environment without worrying about protocol specific intricacy. Five languages are currently supported: C, C, Java, Node.js, and Python. We strive to maintain consistency of APIs across the five languages, as much as language specific constructs allow.

Increase your visibility and reach more customers by publishing in the cloud marketplace

With the SDKs, your solution is future-proof with less hassle down the road. The SDKs expose simple protocol agnostic APIs for advanced features of IoT Hub so you can leverage new features with minimal code. For example, IoT Hub released afile uploadfeature which allows devices to upload files to the cloud. To use this feature in your solution, you only need to update the SDKs to a version that supports this feature, and make the call to IoTHubClient_UploadToBlobAsync() in your solution (API shown for C SDK). Some features come for free. Instead of implementing a retry logic for your solution, you get the industry best practice for retry logic exponential backoff with jitter as the default.This is much faster than writing and maintaining your own custom implementation for these advanced features.

The SDKs include several reliability features as well.

Develop with your preferred language for different platform:

Learn about Azure security, compliance, and privacy

Accelerate partner connections and amplify success through the Microsoft partner ecosystem

Depending on your IoT scenario, sending data too frequently may incur avoidable costs.The SDKs provide several out-of-the-box solutions for bandwidth savings.Buffering allows the device to store data when connectivity is poor instead of attempting retries. Batching reduces the number of messages transmitted by merging information from multiple messages into a single batch of messages, thus reducing network bandwidth usage. Multiplexing reduces the number of connections by having multiple devices share the same connection.

Code snippets from the SDKS are shown to demonstrate concepts.Here is where you can find a comprehensive list of our SDKs.

The SDKs are developed by Microsoft engineers and go through a rigorous engineering process to ensure quality. Features are covered with both unit and end-to-end tests. Prior to each bi-weekly release, the SDKs are tested with a gated build system for supported platforms to ensure no regression.

Extend cloud intelligence and analytics to edge devices

Some developers are wary of behavioral or functional breaking changes that may affect devices in the field. The Azure IoT Hub service is a PaaS that exposes bare APIs that are versioned, guarantying continuity of behavior and function when using with a specific version of the service API. To further and complete this engagement at the client level, the SDKs offer a Long Term Support (LTS) version.LTS branches are shielded from unwanted changes. They will still receive all security bug fixes and critical bug fixes.A new LTS version will be created every 6 months with one-year lifetime.
