IT admins are expected to keep the organization’s network reliable and resilient all while the complexity of today’s networks grows. From adopting hybrid infrastructures and maintaining multi-cloud environments’ security to managing ever-increasing bandwidth demands, enterprise network management is getting more difficult by day.

Grafana is a powerful open-source visualization solution that provides valuable insights into the performance of infrastructure, applications, and servers. With customizable visualizations and support for diverse data sources and formats, Grafana allows IT teams to collect and visualize data from various sources.

This blog expands our technical deep-dive into a real-time kernel. You will need to be familiar with a real-time kernel to understand the tuning concepts in this blog. If you are starting from scratch and need to revisit the basics of preemption and a real-time system, watch this introductory webinar. If you are interested in the primary test suites for real-time Ubuntu, an explanation of the components and processes involved, head over to the first part of this mini-series.

In the realm of virtualization, snapshots play an integral role in managing virtual machines (VMs). Essentially, a snapshot captures the state of a VM at a specific point in time, providing a reference point to which you can revert if necessary. This can be especially handy when implementing changes to your VM or its applications, allowing you to quickly undo the changes if they cause any unforeseen issues.

Cloud security is a constant concern and tends to revolve around common themes - how do you give intended users access to the data and systems their clearance allows, while maintaining a good user experience; and how do you keep unintended users or malicious bots out? In the entanglement of systems, services, and applications that make up a modern IT infrastructure, this is a lot harder to balance in practice than it is on paper.

In this article, we will deploy a clustered Prometheus setup that integrates Thanos. It is resilient against node failures and ensures appropriate data archiving. The setup is also scalable. It can span multiple Kubernetes clusters under the same monitoring umbrella. Finally, we will visualize and monitor all our data in accessible and beautiful Grafana dashboards.

Did you know that data centers are some of the most energy-intensive buildings? They consume 10 to 50 times the energy per floor space of a typical office building. As governments, industry regulators, and customers demand more energy efficient data centers, data center managers are tasked to comply with corporate sustainability initiatives by finding new ways to innovate and reduce energy consumption.
