6 Ways Kubernetes Simplifies Multi-Cloud Management

A multi-cloud strategy is hard. Fortunately, Kubernetes makes it easier. In several respects, Kubernetes helps to solve or work around the most pressing pain points within a multi-cloud architecture. Let’s explore how. Multi-cloud challenges Multi-cloud architectures can deliver a number of benefits, including better cost-efficiency, reliability and scalability. Yet those benefits come with tradeoffs. (Read

Kubernetes Container Registry and Image Scanning

If you’ve been investigating Kubernetes – or any container management system – you might have come across references to an image registry. In this article, we’re going to talk about what an image registry is, and why it’s an essential component of your Kubernetes implementation. We’re also going to discuss registry scanners, and why they’re

Kubernetes Autoscaling Options: Horizontal Pod Autoscaler, Vertical Pod Autoscaler and Cluster Autoscaler

Kubernetes is hailed for making it simple to provision the resources you need, when you need them. However, it’s challenging to know the exact size and number of nodes that best fit your application, especially when you can’t predict what load you will want to support in the future. If you are allocating resources manually,

Kubernetes Monitoring at Scale with Prometheus and Cortex

Kubernetes Monitoring Solutions Deploying Prometheus on Kubernetes Deploying Cortex on Kubernetes Key Metrics ti Track The growing adoption of microservices and distributed applications gave rise to the container revolution. Running on containers necessitated orchestration tooling, like Kubernetes. But managing the availability, performance, and deployment of containers is not the only challenge. It is important to

Stateful applications with Kubernetes

When containers became mainstream, they were designed to support ephemeral – stateless – workloads. Since then, a lot of effort has been made to support stateful applications in the container ecosystem, with a lot of that focus targeted towards better support from core Kubernetes. Stateful applications – and the data they contain – are extremely

Kubernetes for Machine Learning

Machine Learning (ML) is rapidly becoming essential to businesses and institutions across the globe. Each organization must meet the challenge of provisioning a computational infrastructure that can support a resource-intensive machine-learning pipeline. While moving computation to the cloud has become the standard response to the challenge of scalability, machine learning teams have specific needs that

Kubernetes Service Mesh: A Comparison of Istio, Linkerd, and Consul

Cloud-native applications are often architected as a constellation of distributed microservices, which are running in Containers. Increasingly, these containerized applications are Kubernetes-based, as it has become the de-facto standard for container orchestration. One outcome that most companies using microservices architecture don’t fully understand the impact of until they are well down the path is microservices

Kubernetes Security: What (and What Not) to Expect

When it comes to security, there is a lot that Kubernetes does. There is also a lot that it doesn’t do. To secure Kubernetes effectively for real-world deployment, you must understand which built-in security features Kubernetes offers and which it doesn’t, and how to leverage Kubernetes’s security capabilities at scale. Below, we walk through Kubernetes’s

Kubernetes Multi-Tenancy Best Practices

In a simpler world, all Kubernetes deployments would host just a single tenant — meaning only one workload or application runs on the entire Kubernetes environment. In the real world, it’s common to have multi-tenant Kubernetes deployments. In a multi-tenant deployment, multiple workloads share the same underlying Kubernetes infrastructure. Multi-tenant Kubernetes creates some special challenges

SELinux, Kubernetes RBAC, and Shipping Security Policies for On-prem Applications

Security-Enhanced Linux (SELinux) is a swiss army knife for Linux security, which is as relevant in commodity Kubernetes deployments as it was in yesterdays era of artisanally crafted linux server silos. Whether or not you are using cloud native technology, some of the lessons we’ve learned around being transparent, disciplined in your security practices, and
