Feed: The Internet of Things on AWS – Official Blog. Author: Michael Garcia. You can connect securely millions of objects to AWS IoT using our AWS SDKs or the AWS IoT Device SDKs. In the context of industrial IoT, objects are usually connected to a gateway for multiple reasons: sensors can be very constrained and not able to directly connect to the cloud, sensors are only capable of using other protocols than MQTT or you might might need to perform analytics and processing locally on the gateway.One feature of local MQTT broker is called ‘Bridge’ and will enable you to ...

Feed: The Internet of Things on AWS – Official Blog. Author: Brett Francis. Welcome to another installment in the Bites of IoT blog series.In this bite, we will use the AWS IoT rules engine to select and route a message to Amazon Simple Notification Service (Amazon SNS). Specifically, we’ll send a text message to a phone number when someone rings a virtual doorbell. Concepts Covered in This Bite The rules engine is often the first point at which your IoT solution can take actions on a device’s messages (for example, message filtering, routing to other services, and even direct processing ...

Feed: The Internet of Things on AWS – Official Blog. Author: Rameez Loladia. In an earlier blog post about certificates, we discussed how use-your-own-certificate support in AWS IoT lets customers use device certificates signed and issued by their own certificate authority (CA) to connect and authenticate with AWS IoT. This is an alternative to using certificates generated by AWS IoT.Using your own certificate with AWS IoT is a two-step process: The first step is to register the CA certificate that signed and issued the device certificates. After registration, any device certificate that was signed by the CA can be registered ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Brett Francis. Welcome to Bites of IoT, the first post in a series designed to introduce developers to AWS IoT.In this first bite, we’ll set up a very simple client that can create things in AWS IoT, send messages to those things, subscribe to topics to receive messages from things, and then clean up. The client is available through AWS Labs on GitHub. It’s used in this post to illustrate some IoT concepts, but will be used in later posts in this series, too. Before we get into the ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Mohit Srivastava. We are proud to announce two new device SDKs for AWS IoT – the AWS IoT SDK for Java and the AWS IoT SDK for Python. These SDKs add to those already available for AWS IoT:The Java and Python SDKs help you easily and quickly connect your device or application to AWS IoT, send and receive messages using either MQTT or MQTT over the WebSocket protocol, and exchange state information with device shadows (sometimes referred to as thing shadows). All of the SDKs are open-sourced on GitHub, so you ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Ryan Burke. The AWS IoT platform enables you to connect your devices and build scalable Internet of Things solutions with the breadth of Amazon Web Services.When shopping for a new tool, many developers want to be able to test-drive options before making a choice. When evaluating an IoT solution, it’s not practical to do so at scale with physical devices. Building a sensor simulator is the next best choice. With a sensor simulator built on top of AWS Lambda, you can elastically generate device sensors that report their state ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Eeshan Thakar. In AWS IoT, you can create a device shadow (sometimes referred to as a thing shadow) that will be used as a communication layer between your mobile/cloud application and your devices connected to AWS IoT. The shadow is a persistent, virtual representation of your devices. Because it always has a point-in-time view of the state of your device, it’s easy to write applications that interact with your devices through device shadows.When you update the shadow of your device, the Thing Shadows service will typically publish two messages: /update/accepted or /update/rejectedThis ...

Feed: The Internet of Things on AWS – Official Blog. Author: Rameez Loladia. IntroductionAWS IoT now supports Elliptic Curve Cryptography (ECC) for devices connecting to AWS IoT using TLS. You can now request an EC-based certificate for your device from AWS IoT or register your device using an existing EC-based certificate in order to establish a TLS connection. You can also connect your devices to AWS IoT using EC-based cipher suites for enhanced security on your TLS communications. This blog will discuss the use of EC-based certificates to establish TLS connections. First, it will describe how to request an EC-based ... Read More

Feed: The Internet of Things on AWS – Official Blog. Author: Kyle Roche. The pace at which the world is changing has never been faster than it is today. In the last decade, we have witnessed how mobile and big data are contributing to the next technology revolution: the Internet of Things (IoT). There is a lot of hype around IoT. Is it just that, hype? We want to welcome you to the Internet of Things on AWS Official Blog where we will answer questions about IoT, its thought leaders, and how you can deploy IoT solutions in the cloud.Telecom operators are ...

Summary: DDL trigger does all the magic of automatic support of historical data, all you need is to run the script against your database (once). After that you can turn history on tables on, off, or pause it. It will keep audit of all schema changes in your database and automatically generate DML triggers on tables. If you change the schema of the table where history enabled, for instance add or remove column, the same change will be applied to the corresponding history table, so you'll never forget to sync main table with history. Application Sometimes Business requires to keep ... Read More
