"Unlocking the Power of Observability: Emerging Trends to Watch"
As technology continues to evolve, organizations are facing increasing complexity in keeping applications running reliably and performing well. Traditional monitoring approaches often fall short, leading to a new paradigm: observability. This approach enables teams to understand their systems' behavior, anticipate problems, and troubleshoot effectively.
Key trends emerging in observability include:
* Unified observability platforms that merge metrics, logs, and traces for real-time system performance and health insights
* Distributed tracing that allows developers to pinpoint performance bottlenecks or errors in complex distributed systems
* Observability-driven development (ODD), which encourages building visibility into applications during development stages
These advancements leverage AI and machine learning to auto-detect anomalies and provide real-time root cause analysis. Additionally, "observability as code" enables teams to define and manage configurations using code-based tools and procedures.

Kubernetes users, take note! OOMKilled errors can occur when containers exceed memory limits or access unavailable resources on a node. Here's what you need to know:
* OOMKilled is flagged by exit code 137 and indicates that pods must use less memory than available on the node.
* Check the Events section of the describe pod for messages indicating memory issues.
* Note that even if a pod is terminated due to memory exhaustion, it may still restart if the node's restart policy is set to 'Always'.
* Use commands like `kubectl get pod -o jsonpath='{.status.qosClass}'` and `kubectl get pod -o jsonpath='{.spec.containers[0].oomScoreAdmission}'` to inspect QoS classes and oom scores.
By understanding OOMKilled errors, you can better troubleshoot and optimize your Kubernetes deployments.

Deploying NestJS Applications using Vercel and Supabase: A Step-by-Step Guide
Are you looking to deploy your NestJS application using Vercel and Supabase? This guide provides a step-by-step walkthrough of the process. First, set up your Supabase account and create a new project. Connect your PostgreSQL database and test the connection on your local machine. Next, create a new project in your Vercel account and connect it to your Git repository. Import your .env file and click the Deploy button.
However, you may encounter an error message during deployment. This is due to Vercel needing to know your output directory during the build process. To fix this, add a vercel.json file with the necessary configuration. Run deployment again, and you should be able to deploy your application successfully.

The rise of no-code and low-code development platforms is revolutionizing the way software is created. These innovative tools enable users with varying levels of technical expertise to build applications quickly and efficiently, leading to increased innovation and cost savings. By leveraging graphical user interfaces and pre-built templates, no-code platforms allow non-technical individuals to design, develop, and deploy apps without writing a single line of code.
Low-code platforms offer a more adaptable approach, allowing users to construct apps with minimal coding while still providing room for customization via traditional coding. This versatility appeals to both professional developers and citizen developers, striking a balance between ease of use and depth of capability.
The benefits of no-code and low-code platforms are far-reaching, empowering individuals from diverse backgrounds to contribute to the development process. By streamlining application creation, these tools enable organizations to respond swiftly to market demands, test new ideas, and fine-tune existing apps based on customer feedback.
Collaboration between IT and business units is crucial for successful application development. No-code and low-code platforms facilitate this collaboration by providing a shared space for users to share knowledge, best practices, and resources.
While these platforms hold great promise, it's essential to acknowledge the challenges and considerations that come with their adoption. Organizations must ensure they maintain code quality and architectural integrity, address technical debt, and establish governance frameworks to prevent security risks.
