The Techy Boy

Modern software infrastructure rests on the ability to manage, scale, and automate containerized applications at a scale that was once unthinkable. Before this technology became a global standard, it was the engine behind Google’s massive internal operations. Known as   "Borg,"   this system managed millions of containers, handling the deployment and health of nearly every internal service Google offered. In 2014, Google open-sourced a descendant of this system, giving birth to  Kubernetes —a platform that triggered a tectonic shift in how the industry approaches distributed systems. 1. The "K8s" Name is a Math Joke In the world of cloud-native engineering, you rarely hear the full four-syllable name. Instead, professionals call it  "K8s."  This is not a random nickname but a  "numeronym,"  a specific brand of engineering shorthand where the number represents the count of omitted letters. K  +  u-b-e-r-n-e-t-e  (8 letters) +  s ...

  What are Azure Locks? Azure Locks are a powerful tool that allows you to restrict changes to Azure resources. By applying a lock to a resource, you can prevent unauthorized modifications, ensuring the integrity and security of your Azure environment. Types of Azure Locks There are two main types of Azure Locks: ReadOnly: This lock prevents any modifications to the resource, including updates, deletions, or changes to its properties. CanNotDelete: This lock prevents the deletion of the resource, but allows updates to its properties. Advantages of Using Azure Locks Enhanced Security: Prevent unauthorized changes to critical resources. Compliance Adherence: Ensure compliance with regulatory requirements or internal policies. Resource Protection: Protect resources from accidental deletions or modifications. Change Management: Implement a controlled process for making changes to resources. Common Use Cases for Azure Locks Protecting critical resources: Lock down highly...

Hey developers! 👋 We all have faced endless debugging, repetitive tasks, or struggled to get the perfect design. But what if AI could make things easier for us? 😅 In this post, I'll share some AI tools that have helped me save time and make web development less frustrating. If you’ve got your own favorites, feel free to share in the comments—I’d love to know what’s working for you! GitHub Copilot: Your Coding Buddy 🤖 You might have heard about GitHub Copilot. It’s like having a coding partner who suggests code completions and helps you write boilerplate code. Great for speeding up your workflow, especially with repetitive tasks. Why it’s useful: It suggests code as you type—sometimes even entire blocks! Works with many languages, like JavaScript and Python. You can learn new coding techniques along the way. Question: Have you tried Copilot? Has it made a big difference in your coding process? Tabnine: ...

F5 failover refers to the process of switching from a primary (active) F5 load balancer to a secondary (standby) F5 load balancer in the event of a failure or maintenance requirement. This ensures continuous availability and minimizes downtime for applications and services relying on the load balancer. F5 Networks provides a range of products, including the BIG-IP platform, which supports high availability (HA) configurations to enable failover. Key Concepts High Availability (HA) : F5 BIG-IP devices can be configured in HA pairs to provide redundancy. One device is active (handling traffic), and the other is standby (ready to take over if the active device fails). Failover Mechanisms: Failover can be triggered by various conditions, such as hardware failures, software issues, or manual intervention. The standby device continuously monitors the active device and takes over when it detects a failure. Sync-Failover Device Group: F5 devices in an HA pair are part of a sync-failover device...

Introduction DevOps is fast becoming an essential aspect of many company cultures for numerous reasons. This guide outlines how to properly implement DevOps using the right tools and, crucially, the right mindset. However, implementing DevOps is more than just adopting new tools and practices. It’s about fostering a culture of continuous innovation and incremental improvement. Although challenging, the benefits of a robust DevOps culture are undeniable. DevOps is a critical foundation that empowers organizations to innovate, learn, and improve, driving business success. Step 1: Leverage the Best Metrics When initiating DevOps, start with clear end goals in mind. Metrics are crucial for tracking progress and ensuring a successful journey. The DORA State of DevOps 2019 report highlights key metrics to benchmark your DevOps transformation: Deployment Frequency : How often you deploy code to production or release it to end-users. Lead Time for Changes : The duration from code commit to run...

Using Git as your go-to code versioning tool is a daily routine for developers, often managed through the command line. Even if you prefer a dark-themed GUI, sometimes you just need to dive into the CLI. In this article, we'll explore 10 Git aliases that can streamline your workflow, whether you're working solo or within a team. Let's dive in and make your Git game stronger! Setting Git Aliases Your Git aliases are usually stored in your user configuration file, typically located at ~/.gitconfig. You can manually set aliases using commands like git config alias.s 'status -s' . Listing Git Aliases To see all your Git aliases, use the command git config --list --show-origin , which lists all Git configurations along with their origins. 1. Git Status Do you find yourself frequently checking your Git status? Create an alias for it: bas [ alias ] s = status Now you can simply type git s to check your status. 2. Git Checkout Switching between branches is a common tas...
