Apache Kafka is widely used for building distributed, real-time data pipelines. However, running Kafka in a production environment requires a solid setup to ensure performance, reliability, and scalability. Strimzi simplifies deploying and managing Kafka clusters on Kubernetes or OpenShift, but to be truly production-ready, several factors need to be considered. In this article, we will cover essential best practices and optimizations to make your Kafka cluster ready for production, based on insights from the Strimzi Production Ready series and additional knowledge. ...

A lot of Reddit users say that CKAD is easier than CKA. Personally, I agree—it does feel lighter if you attempt CKAD after completing CKA. The CKAD focuses more on scheduling tasks, while CKA involves administration of clusters. So, in CKAD, it’s more about speed and being quick with your typing to finish all the questions in time. 🏃‍♂️🕒 My Study Approach After passing the CKA two weeks earlier, I had a pretty good idea of what the exam interface and questions would be like. I compared the CKA and CKAD certifications to see what additional topics I needed to cover for CKAD. ...

Last November, I scheduled my CKA exam, but guess what? I kept putting it off for months. Every time I thought about studying Kubernetes, it felt like I was facing an enormous mountain I wasn’t ready to climb. Life got busy, I lost motivation, and the exam remained on hold. In July, I bought the KodeKloud CKA course, thinking it would push me to start studying. I studied a little, then stopped, and this cycle went on for weeks. Kubernetes seemed too big and complex to handle, and I didn’t know where to begin. And then, life happened—my father was hospitalized, and I had even less drive to study. ...

In 2014, security researchers discovered a critical vulnerability in the HSBC mobile banking app for iOS. The app was found to be susceptible to man-in-the-middle (MITM) attacks, allowing attackers to intercept and manipulate sensitive financial information. The root of the problem? The absence of SSL pinning. Without SSL pinning, the app was vulnerable to accepting any SSL certificate, even a forged one, which enabled attackers to eavesdrop on the communication between the app and HSBC’s servers. This security flaw put users’ banking information at risk and highlighted a significant gap in the app’s security framework. ...

Joshua had been waiting anxiously for weeks. As an aspiring clerk, he knew that the government official’s appointment order could arrive any day. This appointment was crucial—it would determine his future and career. Every morning, Joshua checked his local post office, hoping that today would be the day the letter arrived, confirming his new position. In many ways, Joshua’s experience mirrors how Kafka, a powerful distributed streaming platform, manages and delivers data. Just like how Joshua relies on the postal system to receive his appointment letter, modern data systems depend on Kafka to ensure that critical information reaches its intended recipients quickly and reliably. ...
