Cloud Native Doesn’t Mean Breaking Everything You Own

You've probably heard lots of talk about "cloud native computing," but if your world revolves around applications built around virtual machines—for example, if you're a VMware shop—you may think it's not an option that's open to you. Fortunately, that's not the case. With today's technologies, it's possible to take advantage of cloud native computing without having to rewrite every piece of software you've been using all these years.

Ultimately, yes, you want to be in a position where your applications are all cloud native and you can take advantage of technologies like containers and orchestrators such as Kubernetes to ensure that your infrastructure is flexible and resilient.

Is your cloud obsolete?

Over the last few months Christian Huebner has advised several customers on upgrading their cloud to the latest version of the Mirantis Cloud Platform suite, and there are a few questions they frequently ask; can the hardware from the current platform be reused, should it be shored up, or should we buy new hardware?

There is no simple answer.

He always looks at the question from the perspective of the customer, so this piece is written from the viewpoint of a fictional cloud owner. It illustrates the advances made in hardware over time and the implications for server designs. However, it should not be taken as a ready-made cloud design; each cloud design recommendation will differ greatly based on the individual use case, and your cloud architect should provide individual optimization.

Persistent Data and Storage with Kubernetes

If you’re a developer whose organization is moving to Kubernetes, there’s a pretty good chance that you’re going to spend some time decomposing existing monolithic applications into microservices that take advantage of Kubernetes’ capabilities. 

In the next few lessons, we’re going to work step-by-step to break down a monolith into dedicated Services running on Kubernetes.

How to Use Kubernetes Secrets with Environment Variables and Volume Mounts

Instead of configuring a password directly through an environment variable, we can use KubernetesSecrets. While they aren’t the be-all and end-all of Kubernetes security, Secrets give us a way to add an additional layer of protection for sensitive data.

How to Use StatefulSets and Create a Scalable MySQL Server on Kubernetes

Now it’s time to dig into what a StatefulSet is, how it works, and why it’s such an important resource for running stateful components like databases on Kubernetes. This will give us some of the final pieces necessary to complete the decomposition of our monolithic To Do app. 

CN252 Cloud Native Development Boot Camp

Quickly learn the core skills you need to develop high performance, secure containerized applications and orchestrate them on Kubernetes before deep diving into advanced techniques for streamlining the container development process, instrumenting containers for production systems, and building fully containerized continuous integration pipelines.

CN251 Cloud Native Operations Boot Camp

An intensive training bootcamp for IT professionals looking to develop skills in deploying and administering containerized applications in Kubernetes. Start by learning about first principles for application containerization, then learn how to stand up a containerized application in Kubernetes, and, finally, ramp up your skills for day-1 operating tasks for managing a Kubernetes production environment.

Multi-Tenancy and Isolation using Virtual Clusters (vCluster) in Kubernetes

Multi-tenancy in Kubernetes allows customers to share compute resources within a cluster. Each tenant’s workload is isolated and remains invisible to other tenants, providing additional security and flexibility to the developers. This is possible using namespaces and RBAC, but it is not easy to isolate all the resources and is often complex to achieve full isolation.

How to Give Developers Secure Access to Kubernetes

Setting up a Kubernetes service has become relatively easy, whether it be on-premise or in public cloud services. However, giving secure access to developers can be a painful process involving cluster certificates, access management systems, networking setup, and firewalls.

Managing Kubernetes Security Using Kubescapes & Lens

Cloud environments & Kubernetes are becoming more and more expensive to operate and manage and increasingly harder to secure. In this demo-rich Tech-Talk, Mirantis and ARMO will demonstrate how to easily scan Kubernetes configurations, Container Vulnerabilities, and configure Role-Based-Access-Control.

What is a Service Mesh and how to get started with it

A service mesh is a tool for adding observability, security, and reliability features to applications by inserting these features at the platform layer rather than the application layer.

Why should developers care about container security?

Why, exactly, should I care about things like Dockerfile image users and read-only filesystems? Why do people keep harping on image sizes? What do CPU and RAM limits have to do with appsec?

Did you know that 90% of managers are willing to pay for certifications?  (Source: The 10th Annual Open Source Jobs Report produced by the Linux Foundation.) Check out this video to see how Mirantis Training can unleash your cloud potential today.
