Kubernetes has revolutionized container orchestration, allowing developers to deploy and manage applications at scale. However, as the complexity of a Kubernetes cluster grows, managing resources such as CPU and memory becomes more challenging. Efficient pod scheduling is critical to ensure optimal resource utilization and enable a stable and responsive environment for applications to run in.

When it comes to storing data in the cloud, there are many options to choose from. Azure, one of the leading cloud service providers, offers a wide range of storage options, including Azure Blob Storage and Azure Table Storage.

DevOps has exploded in popularity since the concept first emerged in 2009. A DevOps approach encompasses both practices and tools that engineers use to build quality software more rapidly. Before DevOps, software development followed a “waterfall” model. Back then, developers would code first, then perform quality assurance (QA) testing, and fix any bugs or errors as necessary.

In this blog, we will explore how distributed tracing works in Application Insights and how to use it to diagnose the issues in a distributed application. Azure Application Insights is a powerful tool for monitoring and diagnosing application performance issues and supports distributed tracing. It is an extension of Azure Monitor and provides Application Performance Monitoring features out of the box.

The world of DevOps is constantly evolving and adapting to the needs of the software development industry. With the increasing demand for faster and more efficient software delivery, organizations are turning to modern technologies and practices to help them meet these challenges. In a series of articles on the Kublr blog, we will take a look at some of today’s top DevOps trends.

Continuous load testing is a powerful way of preparing for surges in traffic, without needing real users. Imagine you’re a software engineer working on a website that’s seen a recent surge in traffic. Despite initial testing indicating that the website should be capable of handling the increased load, the website crashes during peak hours. Load Testing is the process of simulating real-world usage of a website or application.

Managing a Kubernetes cluster requires a keen eye for detail and a deep understanding of its complex structure. To ensure smooth operation of your applications and optimal performance, it is vital to monitor a wide range of metrics across the different components of your cluster. In this article, we will discuss key metrics that can be used to monitor both self-managed and cloud-managed Kubernetes environments, helping you to keep your cluster running at its best.

It all started with a simple Slack message. If you need a refresher, gross margin is a business metric that calculates what percentage of revenue you take home as profit. To calculate it, you subtract your costs (often abbreviated as COGS, short for costs of goods sold) from your revenue and divide it by your total revenue, et voilà, gross margin. So, if your annual revenue is $10M and your COGS are $3M, your gross margin is 70%. Gross margin plays an integral role in SaaS company valuations.
