Cloud Native: The Future of Application Development

2024-01-30T01:05:43+00:00

If you could do a quick search on the definition of cloud native, chances are you would be confused by the amount of different sources with varying definitions. The term "cloud native" has become a buzzword within the tech industry, symbolizing a paradigm shift in how software applications are designed, developed, and deployed. But what exactly does cloud native mean? The varying definitions of cloud native may be primarily because of its evolving definition over time. While some sources define cloud native as an approach where developers initially design applications to thrive in a cloud environment, others emphasize the utilization [...]

Introduction to Kubernetes

2023-10-16T05:25:03+00:00

Containerization has set the gold standard for deploying applications on both on-premises and cloud environments. As microservices architecture becomes more popular, people increasingly embrace containerization because it naturally fits this architectural approach. Containerization brings many advantages: It guarantees portability. This technology's inherent isolation lets developers deploy their application code on various environments and operating systems without worrying about compatibility. It boosts scalability. Developers can deploy containers quickly and repeatedly. Unlike virtual machines, containers don't require booting up an entire operating system, letting developers scale up or down quickly by adding or removing containers on single or multiple machines. It enhances [...]

Bookmarks Defining a Kubernetes Workload Resource Deployments ReplicaSet StatefulSets DaemonSet* Jobs CronJob Automatic Cleanup for Finished Jobs ReplicationController A workload is an application that can have one or more components running on Kubernetes. A Pod represents a set of running containers in the cluster. Kubernetes allows for declarative configuration of workloads and its components. This will allow the Control Plane to manage the creation, deletion, and modification of these Pods. The built-in APIs for managing workload resources are: Deployments - The most commonly used workload to run an [...]

Bookmarks What is a Pod? What are Kubernetes Services? Kubernetes Service Types Defining a Service Headless Service What is a Pod? A Pod is a Kubernetes Object that has one or more containers running inside it. A Pod will ensure that the containers inside it share the same resources and local network. Each Pod gets its own IP address. If you use a Deployment to run your app, that Deployment can create and destroy Pods dynamically. Pods are created and destroyed to match the desired state of your cluster. Pods are ephemeral [...]

These objects can be created, modified, or deleted via the Kubernetes API. Kubernetes Objects describes the following:        ●    what containerized applications are running and on which nodes.        ●    resources available to these applications.        ●    the policies on how these applications behave such as restart [...]

Bookmarks What are Kubernetes Components? Control Plane Components Node Components Kubernetes Add-Ons What are Kubernetes Components? There are two main components to Kubernetes: Cluster and Control Plane. When deploying Kubernetes, at least one cluster will be created. A cluster contains the following components: ● Nodes. ○ Worker machines that runs containerized applications. ○ Every cluster will have at least one node. ○ Managed by the Control Plane.            ● Pods. ○ Components of an application workload. ○ Managed by the Control Plane. A cluster can be configured to run multiple [...]

This can be a single component or multiple components that work together. An example of a simple workload is a ping workload that runs every hour. An example of a complex workload is a web server that needs [...]
