Here is short info about post: Observability has become an essential practice in modern software engineering. As distributed systems grow in complexity, so does the need for robust monitoring and observability tools. One technology that’s been making waves in this field is eBPF (extended Berkeley Packet Filter). Originally designed for network packet filtering, eBPF has evolved into a powerful tool for monitoring and improving observability in Linux systems. It enables users to run sandboxed programs within the kernel, providing deep insights into the system without modifying ... Observability with eBPF: Unlocking Deep Insights in Linux Kernel

Here is short info about post: RabbitMQ is a popular message broker used widely in microservices, event-driven architectures, and distributed systems. It allows for the decoupling of message producers from consumers, making communication more efficient and reliable. When designing a system using RabbitMQ, an important decision is choosing the type of queue that fits your use case. RabbitMQ provides multiple types of queues, but the most common ones are Classic Queues and Quorum Queues. In this article, we will explore the differences between these two queue ... Deciding Between RabbitMQ’s Classic and Quorum Queues

Here is short info about post: Introduction to Data Migration Data migration is an essential task in today’s digital environment, especially as organizations seek to move data from one platform to another due to cost optimization, feature enhancements, or infrastructure upgrades. One common scenario is migrating data from Dell EMC Elastic Cloud Storage (ECS) to MinIO, two widely used object storage systems. Dell ECS is a software-defined, scale-out object storage system designed to manage unstructured data at scale. MinIO, on the other hand, is a high-performance, ...
