I believe in constantly learning, upgrading skills as well as sharing knowledge with the peers. For the same, I utilise excellent online learning portals and have also contributed content to popular blogs like Geekflare, ButterCMS, MKYong, JavaCodeGeeks and others in the past.
In the dynamic landscape of cloud computing, managing infrastructure effectively is less about static provisioning and more about intelligent, adaptive resource orchestration. Capacity planning, once a periodic, often tedious exercise of spreadsheet projections and hardware procurement, has transformed into a continuous, data-driven discipline. For Site Reliability Engineers (SREs), Software Engineers,…
The world of complex distributed systems is inherently unpredictable. Despite our best efforts in design, testing, and deployment, incidents are not a question of “if,” but “when.” For Site Reliability Engineers, Software Engineers, and Architects, the true measure of an organization’s maturity isn’t the absence of incidents, but rather its…
In the rapidly evolving landscape of distributed systems, microservices, and cloud-native architectures, the terms “observability” and “monitoring” are often used interchangeably, leading to confusion and, more critically, to systems that are difficult to understand and troubleshoot. For Site Reliability Engineers, Software Engineers, and Architects, understanding the nuanced yet fundamental differences…
We’ve all been there. It’s 3 AM, and the pagers are screaming. A critical service is down, customers are impacted, and the on-call team is scrambling through logs and dashboards, trying to piece together a puzzle in the dark. The postmortem later reveals the cause: a rare, cascading failure triggered…
Introduction In the ever-evolving landscape of technology, organizations are constantly searching for ways to optimize their operations and enhance financial efficiency. The advent of cloud computing has brought unparalleled opportunities for scalability and innovation, but it has also introduced new challenges in managing costs effectively. Enter FinOps, short for Financial…
Introduction A Rate limiter service is a system that would help control the rate of requests hitting the end application to which the request is being sent out. A rate limiter could be as simple as DDoS attack protection and as complicated as evaluating user specific criteria before allowing requests…
Introduction In the dynamic world of distributed systems, gaining insights into application performance often relies on effective trace sampling strategies. Distributed tracing provides a holistic view of transactions across microservices, helping to identify bottlenecks, troubleshoot issues, and optimize overall system health. In this article, we’ll explore various trace sampling strategies,…
