Today Enterprise IT does not question the value of containerized applications anymore. Given the move to adopting DevOps and cloud native architectures, it is critical to leverage container capabilities in order to enable digital transformation. Google’s Kubernetes (K8s), an open source container orchestration system, has become the de facto standard — and the key enabler — for cloud native applications, and the way they are architected, composed, deployed, and managed.

kube-proxy is a key component of any Kubernetes deployment. Its role is to load-balance traffic that is destined for services (via cluster IPs and node ports) to the correct backend pods. Kube-proxy can run in one of three modes, each implemented with different data plane technologies: userspace, iptables, or IPVS. The userspace mode is very old, slow, and definitely not recommended! But how should you weigh up whether to go with iptables or IPVS mode?

This post demonstrates a *basic* example of how to build a deep learning model with Keras, serve it as REST API with Flask, and deploy it using Docker and Kubernetes. This is NOT a robust, production example. This is a quick guide for anyone out there who has heard about Kubernetes but hasn’t tried it out yet. To that end, I use Google Cloud for every step of this process. The reason is simple — I didn’t feel like installing Docker and Kubernetes on my Windows 10 Home laptop.

Continuing the trend from last year, in 2019 we see more organizations riding the wave of Serverless and Kubernetes, and many are starting to see tangible results. The widespread adoption of these technologies, however, has only just begun. Below, we examine five trends in serverless that are sure to impact the way organizations develop and deliver software for years to come.

New technologies often require changes in security practices. What is remarkable about containers and Kubernetes, is that they also provide the potential for enhancing and improve existing security practices. In this post, I will share a model that we use at Nirmata to help customers understand security concerns and plan Kubernetes implementations that are secure.

Learn how to support a continuous adaptive risk and trust assessment (CARTA) approach leveraging accurate Kubernetes flow logs. 5-tuple logging is commonly used to monitor and detect anomalies and produces unreliable data that cannot accurately identify anomalies nor prove enforcement of security policies.

Learn how Anomaly Detection supports, what Gartner has termed, a continuous adaptive risk and trust assessment (CARTA) when building a CaaS platform using Kubernetes. Anomaly Detection expands the zero trust network security model and continuously assess the application and network risk that enables adaptive policy adjustments.

Learn how to support, what Gartner has termed, a continuous adaptive risk and trust assessment (CARTA) when building a CaaS platform using Kubernetes. Network security enables microsegmentation and is a core component of a zero trust security model. It allows you to protect your workloads against threats without relying on assumptions about the network, infrastructure, and workloads.

The Domain Name System (DNS) is used to associate IP addresses with meaningful names. By default, Kubernetes clusters configure internal DNS to provide for service discovery automatically. This makes it easy for workloads to locate and work with each other on Kubernetes clusters.
