How to pre-configure EC2 instances using AWS CDK and avoid a nasty trap?

It has been a while since I created a public GitHub repo, but this topic deserves a proper explanation. I was helping a customer solve that specific issue and decided to write about it to help others avoid hours of debugging. That was not an AWS CDK bug but a lack of understanding of how AWS works under the hood. https://github.com/LMtx/AWS-CDK-EC2-user-data Let me know if that topic is interesting for you!

AWS Greengrass - my (un)favorite IoT service.

AWS IoT Greengrass is an open-source Internet of Things (IoT) edge runtime and cloud service for IoT applications. It is my (un)favorite IoT service. Pros: Runs on edge devices. Communicates with local devices. Exports telemetry data to AWS Cloud. Provides remote software upgrade capabilities. Collects and analyzes data where it is generated. Cons: The initial setup is challenging. Adds maintenance overhead. Easily breakable. Hard to debug. Complex. What do you think?

Establishing MQTT Connection with Private Key - is that secure?

In this video, I discuss using a Private Key in the MQTT connection setup. It's crucial to keep the Private Key confidential and not share it with any third party. At the same time, we must provide that key during the connection. Is that secure? I often get that question. In this video, I share my answer. https://youtu.be/q3CPQn8Oy1I

CI/CD in IoT: the "T" (Thing) component 📡

Continuous integration and delivery (CI/CD) is a powerful approach to software development that enables teams to deliver high-quality software faster. However, implementing CI/CD in the IoT domain presents unique challenges due to the "T" (Thing) component. The "T" in IoT refers to the physical devices interacting with the real world. These devices can be anything from sensors and actuators to smart appliances and vehicles. They are often resource-constrained and have different operating systems and architectures than traditional cloud and server-based systems. This heterogeneity makes it difficult to automate the testing and deployment of IoT software. Traditional CI/CD tools and techniques are not well-suited for handling the unique challenges of IoT development. One way to address these challenges is to use software abstractions to emulate devices. This enables developers to simulate the entire IoT infrastructure, including the devices, the network, and the cloud. This allows them to test their software in a controlled environment and identify potential issues early on. Another way to address the challenges of CI/CD in IoT is to adopt a microservices architecture. This involves breaking down the IoT system into small, independent services that can be developed, tested, and deployed independently. This makes it easier to automate the CI/CD process and to scale the system as needed. By addressing the challenges of CI/CD in IoT, organizations can improve the quality of their software, reduce time to market, and enable faster innovation. 🤖 👉 How do you implement the CI/CD paradigm for Internet of Things deployments? 💡

What if AWS decides to shut down the AWS IoT Core?

Devices communicate with the AWS IoT Core using MQTT Protocol and authenticate using X.509 Certificates - neither of those technologies is AWS specific. If AWS decides to shut down the AWS IoT Core (which is rather unlikely), you will be able to migrate to any other MQTT Broker (hosted on-site or cloud offering). In my opinion, vendor lock-in is not severe, considering solely the communication with devices. Naturally, the IoT platform leverages far more services than exclusively communication-related. Moving the entire IoT platform from AWS to another provider would be way more painful. Would you move your entire IoT Platform to another provider or just the communication part? 1. I would move everything. 🧰 2. I would only move the connectivity and keep the rest in AWS. 📡 Please share your opinion! 💬

What are the main factors that affect the cost of cloud infrastructure utilized by the IoT solution?

The frequency of telemetry messages is one of the primary cost factors in IoT solutions. Implementing edge analytics is a cost-effective strategy that enables savings while providing real-time capabilities. 👍 I recommend pre-processing and aggregation at the edge to reduce expenses associated with frequent messages. 💰 To further optimize cloud-side costs, analyze and buffer data BEFORE storing it. That step is often overlooked but can provide significant savings in specific scenarios (for example, when storing data using AWS S3 Bucket). 💡 Would you be interested in discussing that topic further? 👈
