Todays applications must simultaneously serve millions of users, so high performance is a hard requirement for this heavy load. When you consider marketing campaigns, seasonal spikes, or social media virality episodes, this demand can overshoot projections and bring systems to a grinding halt. To that end, monitoring performance and load testing has become an integral part of app development and deployment: it mimics real application performance under stress, and with this kind of testing, teams

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.

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.

While these errors don’t cause system failures, they introduce significant performance overhead that can impact user experience and operational costs. Study by Lee et. al explores how prevalent are non-fatal errors and what impact do they have on the exposed latency of top-level requests?
