What is a Single-Line Diagram and What is It Used For?

A single-line diagram (also known as an SLD or one-line diagram) is a simplified representation of an electrical system. Symbols and lines are used to represent the nodes and connections in the system, and electrical characteristics may be included as well. In a data center, a single-line diagram is used to visualize the power distribution system to improve planning and troubleshooting, ensure redundancy, and reduce potential outages.

What is Logging as a Service (LaaS)?

Logging as a Service, or LaaS, is a proven approach to managing and monitoring high-volume log data in modern dynamic environments. LaaS allows companies to manage log data regardless of whether it comes from applications, servers, or devices. With LaaS, companies can more easily aggregate and collate data, scale and manage storage requirements, set up notifications and alerts, and analyze data and trends. It also allows teams to customize dashboards, reports, and visualizations.

How reliability testing and load testing are complementary

How can you tell if your systems are reliable when under load? A common answer is to open your observability dashboards, wait for a high-traffic event (like Black Friday), and cross your fingers. While this approach is certainly effective, it's far from ideal. Without proactive reliability and load testing, we have no idea if a system will hold up to real-world usage patterns, which could mean a production outage at the worst possible time.

Auto-scaling of Intel FlexRAN components based on MicroK8s and Ubuntu real-time kernel support

RAN has incrementally evolved with every generation of mobile telecommunications, thus enabling faster data transfers between user devices and core networks. The amount of data has increased more than ever with an increase in the number of interlinked devices. With existing network architectures, challenges lie in handling increasing workloads with the ability to process, analyse and transfer data faster. The 5G ecosystem requires virtual implementations of RAN.

A practical guide to capturing production traffic with eBPF

Monitoring HTTP sessions offers a potentially powerful way to gain visibility into your web servers, but in practice, doing so can be complex and resource-intensive. Extended Berkeley Packet Filter (eBPF) technology allows you to overcome these challenges, giving you a simple and efficient way to process application-layer traffic for your troubleshooting needs.

How to Create K6 Load Tests from API Recordings

Load testing is one of the most common ways to test the resiliency of your applications. In this blog we show how recording production data with Speedscale and exporting to a K6 load tests gives you the best of both worlds. Whether or not it’s important for your organization, there are clear benefits to be had from implementing these types of tests. By doing so, you can: When it comes to load testing, two of the most modern tools are Speedscale and K6.

How to Test Autoscaling in Kubernetes

In an ideal world, you want to have precisely the capacity to manage the requests of your users, from peak periods to off-peak hours. If you need three servers to attend to all the requests at peak periods and just one server at off-peak hours, running three servers all the time is going to drive up expenses, and running just one server all the time is going to mean that during peak periods, your systems will be overwhelmed and some clients will be denied service.

Keeping Track of Kubernetes Deprecated Resources

It’s a fact of life: as the Kubernetes API evolves, it’s periodically reorganized or upgraded. This means some Kubernetes resources can be deprecated and later removed. We deserve to keep track of those deprecations and removals easily. For that, we have just released the new deprecated-api-versions policy for Kubewarden, our efficient Kubernetes policy engine that runs policies compiled to Wasm.
