Migrating from Amazon RDS to DynamoDB can be a significant challenge, especially when transitioning from a relational database like RDS (PostgreSQL, MySQL, etc.) to DynamoDB, a NoSQL, key-value store. One of the most effective strategies for migrating data incrementally is the Dual Write approach. This allows you to keep both databases in sync during the transition, minimizing downtime and reducing the risk of data inconsistency.

Distributed traces are essential for understanding microservices behaviour, performance, and reliability. They provide insights into service dependencies, call graphs, and runtime dynamics, enabling researchers to develop and test tools for optimisation and fault diagnosis. However, there is a noticeable gap in terms of publicly available real-world distributed tracing datasets for microservices architecture research to bridge the divide between theoretical research and real-world implementation

Spring WebClient is a reactive, non-blocking HTTP (HyperText Transfer Protocol) client designed for making requests to external services. It belongs to the Spring WebFlux framework and provides advanced, scalable handling of HTTP requests more efficiently than the RestTemplate. WebClient also supports parallel and reactive programming, making it suitable to perform a large volume of operations without blocking requests.

AWS EC2 Autoscaling is frequently regarded as the ideal solution for managing fluctuating workloads. It offers automatic adjustments of computing resources in response to demand, theoretically removing the necessity for manual involvement. Nevertheless, depending exclusively on EC2 Autoscaling can result in inefficiencies, overspending, and performance issues.

Today, users' expectations of seamless performance mean the system cannot afford downtime or disruption that might turn into losses in revenue and reputation. Therefore, no one can underestimate the role of stress testing in ensuring that the systems are resilient against unfortunate events and failures. Indeed, chaos engineering is an innovation concerning testing infrastructure resilience these days.

Use Cases for Filters Results Filter Plugin The standard JMeter tool does not have a filter on the overall performance load test results. Filters exist for some standard graphs and also when generating the HTML report, but it lacks a powerful global results filter tool. It is often necessary to filter results to show only the pages and not all the URLs that make up the page.

The rise of service-oriented architecture (SOA) and microservices architecture has led to a major shift in software development, enabling the creation of complex, distributed systems composed of independent, loosely coupled services. These architectures offer numerous benefits, including scalability, flexibility, and resilience. However, the distributed nature of these systems introduces new challenges related to understanding, managing, and analysing their behaviour.

If youre an experienced developer or a seasoned computer user, you might recall a time when having 128MB of RAM was considered a luxury. For those who dont know, are too young, or started using computers more recently, let me put this into perspective: the original Max Payne video game required just 128MB of RAM, as did GTA: Vice City. This meant that a computer needed only this amount of memory to run the game alongside all other programs.
