The recent heatwave that brought record temperatures to the UK caused cooling systems to fail at a London data center resulting in downtime for Google and Oracle. According to Oracle, “Following unseasonably high temperatures in the UK south (London) region, two cooler units in the data centre experienced a failure when they were required to operate above their design limits.
The days in which a business could thrive by serving customers through brick-and-mortar stores alone are long gone. Almost all retailers now offer a variety of online and offline channels, often with some degree of integration to ensure a smooth customer journey across different touchpoints. However, even these multichannel and cross-channel strategies are increasingly falling short of modern expectations.
Thinking about breaking into the DevOps space? DevOps has become one of the biggest tech buzzwords. Tech giants – like Facebook, Amazon, or Google – have numerous open positions for DevOps engineers. But it is a competitive field to break into. So if you’ve been prepping for DevOps roles, here are some of the most common interview questions (and potential answers) to expect, including.
Cilium is a Container Network Interface (CNI) for securing and load-balancing network traffic in your Kubernetes environment. As a CNI provider, Cilium extends the orchestrator’s existing network capabilities by giving teams more control over how they build their applications and monitor traffic. For example, vanilla Kubernetes installations typically rely on traditional firewalls and Linux-based network utilities like iptables to filter pod-to-pod traffic by an IP address or port.
In Part 1, we looked at some key metrics for monitoring the health and performance of your Cilium-managed Kubernetes clusters and network. In this post, we’ll look at how Hubble enables you to visualize network traffic via a CLI and user interface. But first, we’ll briefly look at Hubble’s underlying infrastructure and how it provides visibility into your environment.
In Part 2 of this series, we showed how Hubble, Cilium’s observability platform, enables you to view network-level details about service dependencies and traffic flows. Cilium also integrates with various standalone monitoring tools, so you can track the other key metrics discussed in Part 1. But since the platform is an integral part of your infrastructure, you need the ability to easily correlate Cilium network and resource metrics with data from your Kubernetes resources.
An Active Directory (AD) environment has things like forests, trees, domains, organization units, and objects. After growing acquainted with these concepts, the next step on this learning journey is to understand AD sites.
