Imagine you have a perfectly working Kubernetes cluster, and when everything seems on course, you get an “ImagePullBackOff” error. Although this is a popular issue in Kubernetes, understanding and troubleshooting the root cause can be a real headache. Kubernetes is an open-source container orchestration platform originally developed by Google.
Docker has revolutionized how developers work by offering a powerful platform for creating, shipping, and running container applications. It helps developers conquer the complexity of application development and significantly increases software shipping frequency. Despite setbacks in recent years, Docker brings home $50 million in revenue every year, driven by the ongoing demand for new applications.
When you think about hacking stuff, you probably don’t consider thermometers and pacemakers. But imagine the implications if that chunk of metal inside your body suddenly starts acting weird. From the humble thermometer to the sophisticated MRI machine, these gadgets are vital cogs in the healthcare machine and potential Trojan horses if not correctly secured.
On the one hand, your sales department is pushing for new features at an alarming rate, forcing you into faster deployment processes. On the other hand, you have the looming threat of millions of dollars in damages if your security is breached. Software development is all about finding the middle ground – if you can’t compromise on either side, what should you do?
In 2018, the discovery of the Meltdown and Spectre CPU vulnerabilities sent shockwaves through the tech industry. These hardware flaws allowed attackers to steal sensitive data like passwords and encryption keys from computers, smartphones, and cloud servers. Now, in 2023, history is unfortunately repeating itself. A new exploit called Zenbleed has emerged, taking advantage of similar speculative execution processes in AMD’s Zen architecture chips.
What do ambulances in the UK, the Norwegian government, and a major Russian bank have in common? They were all victims of successful supply chain attacks in July 2023. Could you be next? It’s more likely than you think. Organizations entrust more sensitive data to vendors and third parties (like government agencies and critical infrastructure operators) than ever as part of their software development and operations.
Welcome to the world of Docker containers, where the power of isolation and portability meets streamlined application development. Whether you’re an experienced Docker user or just starting your containerization journey, effectively understanding and utilizing WORKDIR can significantly enhance your development workflow. 61% of respondents to a recent Statista survey said they use Kubernetes, putting Docker and Kubernetes among the most in-demand skills by software firms globally.
Containerization is the most popular approach for all modern cloud deployment. This technology makes it possible to encapsulate application workloads as OS-agnostic containers. The result is a new breed of cloud-native applications running across any infrastructure, scaling up or down based on demand. Consequently, there is a need to orchestrate these containers to deliver maximum efficiency in workload execution.
There is an old joke among cybersecurity professionals that the only way to truly secure your data is to keep it on a machine without connection to power or the internet… oh, and put it in a sealed cave. And even then, it is not 100% secure. In today’s world, it’s a pretty safe assumption that none of our data is truly secure.
With the increasing threats of cyber attacks, safeguarding sensitive data and digital assets has become one of the key considerations of modern organizations. According to The State of Security 2023 report, cyber attacks happen every 39 seconds, and a critical security issue can cause a median of 14 hours of downtime. As a result, organizations are turning to security automation tools to effectively mitigate software risks and respond to security incidents promptly.
