Open AWS Glue Create a Database The database will store metadata about your tables. Create a Crawler A crawler scans your data source (like S3) and automatically builds a table in the Glue Data Catalog. When it finishes, you’ll see a new table under your Glue database. Create an ETL Job Now we’ll transform and move the data. AWS Glue will now extract, transform, and load your data to the target bucket. Check the Output
Monitoring infrastructure is crucial for system administrators and DevOps teams. Prometheus, a powerful open-source monitoring and alerting toolkit, is widely used for collecting and visualizing system metrics. However, to monitor a remote system, you need an agent running on that system and Node Exporter is Prometheus’ recommended tool for this job. Prerequisites Before proceeding: What is Node Exporter? It is a Prometheus exporter for hardware and OS metrics. It runs on client machines and makes
Podman (short for pod manager) is an open source tool for developing, managing, and running containers. Developed by Red Hat engineers along with the open source community, Podman manages the entire container ecosystem using the libpod library. Podman helps you to run, build, manage, and debug OCI containers directly within your Kubernetes cluster. Its REST API socket allows remote applications to create and control containers on demand, while providing compatibility with the Docker API and
When you start building applications or infrastructure on AWS, you will quickly realize that your account has default limits (also called service quotas) for how many resources you can use: These quotas help AWS manage capacity fairly across users, but they can become a bottleneck as your workload scales. Elastic IP Quota Elastic IPs are static public IPv4 addresses that you can associate with EC2 instances, NAT Gateways, or Network Interfaces. They’re useful when: By
On a busy Linux server, where multiple applications, services, or background jobs are running —competing for system resources is a natural consequence. You might face slowdowns, high CPU usage, or unresponsive services. To manage such situations, Linux provides built‑in tools to influence process scheduling: nice and renice. These let you assign or change the priority of processes so critical ones get more CPU time, and less critical ones back off. In this blog, you’ll learn:
Introduction As modern Linux distributions transition from iptables to nftables, some compatibility issues are beginning to emerge—particularly for those using iptables-nft, the translation layer between old iptables syntax and nftables. If you’re running AlmaLinux 9 or CloudLinux 9 and have followed steps to install iptables on AlmaLinux 9, you may encounter errors when starting the nftables service. This issue typically manifests with the following error: This error prevents the nftables firewall from loading stored rules,
