This post is part of an ongoing series about troubleshooting common issues with microservice-based applications. Read the previous one on intermittent failure. Queues are an essential component of many applications, enabling asynchronous processing of tasks and messages. However, queues can become a bottleneck if they don’t drain fast enough, causing delays, increasing costs, and reducing the overall reliability of the system.

KubeCon Amsterdam was an incredible gathering of like-minded professionals, bringing together devops, software engineers, vendors, and cloud technology enthusiasts from around the world. This year’s event was the biggest KubeCon + CloudNativeCon ever, with a sold-out attendee list of 10,000 strong. The sheer scale of the event was a testament to the growing popularity of cloud native technology and the vibrant community that supports it.

In your lifetime as a frontend developer that works with React, you must have come across several issues with debugging a containerized React application. I bet you can relate, you’re certainly not alone. Containerization has become an integral part of best practices for software development teams that want to create, test and deploy applications quickly and efficiently. However, despite its advantages, it also comes with new challenges for debugging and troubleshooting applications.

Kubernetes is the container orchestration platform of choice for many teams. In our ongoing efforts to bring the magic experience of Lumigo’s serverless capabilities to the world of containerized applications, we are delighted to share with you the Lumigo Kubernetes operator, a best-in-class operator to automatically trace your applications running on Kubernetes.

As developers, we all seek to build web applications that can scale seamlessly, adapt to changing needs and do so without incurring excessive costs. One way to achieve this is by migrating web applications to AWS Lambda, which can provide scalability, flexibility, and cost savings. To make this process even easier, AWS provides the Lambda web adapter, a simple and efficient tool that enables you to migrate your web apps quickly.

The AWS CDK lets users build as Infrastructure as Code (IaC) reliable, scalable, and cost-effective applications in their cloud environments. With the AWS CDK, developers can use various supported programming languages to create constructs (reusable cloud components) and compose them together into stacks and applications.

Lambda has a size limit of 6MB on request and response payloads for synchronous invocations. This affects API functions and how much data you are able to send and receive from a Lambda-backed API endpoint. I have previously written about several workarounds on the request payload limit. But sometimes you also need to return a payload bigger than 6MB. For example, PDF or image files.

A distributed system is a system whose components are located on different networked computers, which communicate and coordinate their actions by passing messages to one another. The components interact in a decentralized manner and work together to achieve a common goal. Working with distributed systems is challenging, because failure often spreads between components and debugging across multiple components is difficult and time-consuming.

As the world of technology continues to evolve, the demand for cutting-edge solutions to monitor and optimize system performance has never been higher. Today, we’re excited to introduce a revolutionary new concept in observability: Quantum Entangled Observability (QEO). This ground-breaking method leverages the peculiar properties of quantum mechanics to provide unparalleled insights into your systems’ inner workings.

I asked ChatGPT what a software development tool is and got the following response: Software development tools help developers create and deploy software. Examples include code editors, IDEs, and version control systems. They make coding easier, debugging faster, and collaboration smoother. While I agree with most, I’m missing the clear focus on software increments to improve software quality and achieve operational excellence.
