6 Reasons to Utilize Kubernetes on Bare Metal

Kubernetes on public cloud is an adequate solution for small and medium-sized applications that have predictable scaling needs. However, bare metal cloud is the way to go for organizations that look for more control and stable performance.

Container orchestration tools facilitate software development by providing flexibility, portability, speed, and easier scaling for distributed applications. As the de facto leader in the orchestration field, Kubernetes is supported by many popular cloud vendors, who offer managed Kubernetes services.

How to Create a Ubuntu Packer Image and Deploy on a Bare Metal Server

In this blog post, we will discuss how you can create a minimalistic raw Ubuntu image using Packer and then deploy it on a bare-metal server using the provisioning engine, Tinkerbell.

What is Packer?

Packer by HashiCorp is an awesome tool to create pre-configured machine images which can be directly used to create an instance. This should not be seen as a replacement for other configuration tools like Ansible, Chef, etc. Instead, you can use the same tools to pre-configure your image, and with Packer, you can automate the management of your machine images like pushing to an image repository or ensuring your CI pipelines have updated images. Packer also helps you to create parallel builds, i.e you can create multiple images for different platforms using a single template. This enables you to ensure changes in your applications can be tested on multiple platforms simultaneously. It can also be seen as a factor to reduce the parity between developer and production builds.

Bare Metal Vs The World: When And Why To Use This IoT OS

Introduction

Not all operating systems are built equal. In fact, there is plenty of variety when it comes to multitasking, overheads, memory use, and more. This spectrum of choices can make things difficult for Internet of Things (IoT) developers when it comes to choosing the right system for their device.

One type that is uniquely suited to connected devices—at least basic ones—is Bare Metal. Just as a Bare Metal server only hosts one tenant at a time, a Bare Metal environment is entirely dedicated to running a single application. This is in stark contrast to regular operating systems which run multiple programs simultaneously. Let’s take a look at the different types of operating systems and consider which is best when it comes to IoT.

7 Key Services You Need Around Bare-Bone Kubernetes

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. Enterprises are using Kubernetes to create modern architectures composed of microservices and serverless functions which scale seamlessly.

However, two years of working with Kubernetes for enterprise applications, and large-scale production deployments have taught us valuable real-world lessons about the challenges of Kubernetes in the enterprise, and what it REALLY takes in order to make it ready for prime time and enable organizations to safely bet on Kubernetes to power mission-critical enterprise application. Large and complex enterprises that have invested in container-based applications often struggle to realize the value of Kubernetes and container technology, due to operational or day-two management challenges. In this post, we share seven fundamental capabilities large enterprises need to instrument around their Kubernetes investments in order to be able to effectively implement it and utilize it to drive their business.
