Why Now is the Time to Adopt Kubernetes
Kubernetes (K8s), an open source container-orchestration system for app deployment, has been in existence for six years. Over time, it’s developed a very loyal community of users (including myself) who have come to appreciate its many benefits, which include a high amount of fault tolerance and portability. So, you’re probably thinking to yourself, “If it’s been around for six years, why is now the time to adopt Kubernetes?” After working in Kubernetes on multiple client projects, I can honestly say that there’s never been a better time to develop on this platform. Here’s why.Tried and true stabilityThe open source community drives a lot of innovation, which has contributed to Kubernetes becoming an extremely stable platform. It’s also led to incredible tooling to accelerate cloud native development like Skaffold, KinD and Helm. Open source tools like FluxCD and Gatekeeper are used to enable companies to scale up multiple teams delivering to the same k8s cluster while enforcing custom security policies. Bitnami's Kubernetes Production Runtime suite is a collection of standard open source tools that cover the monitoring, logging and ingress needs of a typical production cluster.Write once, deploy anywhereA big payoff of this open source, cloud native development practice is that the same workload and infrastructure can be declared once and run across a variety of cloud vendors. AWS, Google Cloud and Microsoft Azure, among others, all offer managed Kubernetes services, so deploying and scaling your workloads uses the same assets and tooling, no matter what cloud you're on. Developers and stakeholders alike enjoy this portability, which enables them to make decisions based more on application requirements rather than infrastructure limitations. Federated clustering and the Istio project even make it possible to coalesce multiple clusters running across different cloud vendors, geographic regions, and on-premises into a single unit.Big Tech has taken noticeOver the last year, some of the biggest names in technology have been making equally big investments in open source and Kubernetes-related projects and developers. In July 2019, IBM acquired Red Hat, the largest open source software designer on the market, for $34 billion. IBM previously stated that working in the Cloud was one of its four key growth drivers, so with the acquisition of Red Hat, they’re making themselves a more fearsome competitor in the cloud computing race.Earlier this year, there started to be some whispers about Apple hiring a number of well-known Kubernetes and open source software engineers. Insiders say that this can only mean that Apple is finally realizing the value of open source platforms like Kubernetes when it comes to tech infrastructure (an area where, like IBM, Apple has also lagged compared to its competitors).If you’ve considered making the switch to Kubernetes in the past, but haven’t made the jump just yet, I would argue that now, more than ever, is the best time to adopt K8s. With the open source community dedicating six years to stabilizing the platform and developing its consistency and portability, along with huge tech companies making investments in the technology, don’t wait any longer to adopt K8s.About the AuthorThomas Smith is a container evangelist and loves helping craft cloud native solutions.

Knative: The Latest Addition to the Kubernetes Tool Kit
Function as a Service (FaaS) and containers come together with Knative, one of the most exciting things happening in the Kubernetes ecosystem right now, especially if you’re using microservices. Knative components build on top of Kubernetes, abstracting away details, allowing for more elaborate deployments and enabling developers to focus on what really matters. Serverless offerings from Cloud providers often come with fears of vendor lock in. Knative is open source and you can run it either on your own servers or let Google Cloud or Redhat Openshift manage it on their hardware. If you’re an organization that’s already running on Kubernetes, here are three huge benefits to utilizing Knative.Serverless functionsScale-to-zero serverless functions are one of the more elaborate deployments that can be achieved using Knative, and there are some very good reasons to run them in Kubernetes. The first being that you can operate your serverless workloads in the same domain as you do more traditional microservice or monolithic workloads. This simplifies network architecture and makes automated end to end testing easier and faster. If you're already running on Kubernetes, you can reuse the same CI/CD workflows and SRE tools you're already using.Advanced deployment strategiesBeyond running serverless workloads, Knative allows for advanced deployment strategies like blue/green deployments and custom autoscaling controllers. Knative also works with an optional eventing component that deploys a highly available, cloud native Pub/Sub service.Increased efficiencyThe workspace sees many benefits while running Knative, because you can operate in the Cloud using leaner resources. Running all your workloads in the same domain increases efficiency and security. This means a lower operational cost and higher velocity. Plus, a quicker turnaround through the development process, so the end user gets a refined product more quickly.Running Knative will give your development team the toolset to build modern, container-based applications with the flexibility to run anywhere: on premises, in the cloud, or even in a third-party data center. If you build or deploy into the Cloud, keep your eye on Knative.About the AuthorThomas Smith is a container evangelist and loves helping craft cloud native solutions.
