Introduction Real-time systems are now central to modern businesses. Payments, order updates, customer activity, telemetry, notifications, and analytics all depend on events moving quickly and reliably between services. The challenge is not just speed. The challenge is preserving correctness and resilience when systems are distributed, traffic is variable, and failures are inevitable. Apache Kafka […]
Introduction In ad-tech, logs are not “nice to have.” They are the product’s heartbeat. Every impression, every click, every bid request — everything generates logs. Multiply that by millions of requests per minute, and you’re suddenly dealing with millions of events and TB’s of logs per day. That’s exactly where one of our platforms was. […]
Introduction If you’ve worked in production long enough, you’ve probably heard this: “Let’s right-size the services and reduce the AWS bill.” So we do it. We check CPU and memory metrics for a week. We reduce task sizes. Costs drop. Everyone’s happy. And then…. six months later, the bill increases again. Nothing “dramatic” changed. No […]
In this BLOG I will share an incident that taught me how containers really work under the hood. Production Down – Once I received production website down alert for one of my customer. As I checked the website was giving 502 Initial Checks – I immediately logged in to the production host to investigate. The […]
Nowadays, every org wants to migrate to a microservices architecture; the idea sounds great on paper. But when you’re staring at an 8-year or decade-old monolith that processes millions of transactions and somehow never breaks, suggesting a complete rewrite feels… well, insane. I’ve been down this road more times than I care to admit. Be […]
Introduction For over a decade, we’ve relied on AWS Managed Kubernetes (EKS) clusters to deploy our microservices workloads. As businesses increasingly depend on cloud-native applications, security, and compliance have become critical components for ensuring business continuity and growth. These applications, deployed across clusters, need to interact securely with other cloud services, adhering to the principle […]
In the dynamic landscape of distributed systems, communication between services is critical. As modern applications evolve, the need for efficient and scalable communication protocols becomes increasingly evident. One such protocol that has gained significant traction in recent years is gRPC. What is gRPC? gRPC, which stands for gRPC Remote Procedure Call, is an open-source RPC […]
Introduction In today’s rapidly evolving technological landscape, efficient communication and data processing are essential for the smooth operation of distributed systems. Amazon Simple Notification Service (SNS) and Amazon Simple Queue Service (SQS) are two powerful AWS services designed to facilitate messaging and queuing in modern applications. This blog post will delve into the functionalities, benefits, […]
AgileAndroidAutomation Testing
In the era of agile methodologies and DevOps practices, the traditional boundaries between roles are blurring, necessitating a collaborative approach across cross-functional teams. For testers, this entails gaining proficiency in tools beyond their traditional domain, including Kubernetes—a pivotal platform for container management. Let’s explore how test engineers can harness Kubernetes to expedite application quality assessment […]
