Kubernetes Workload Resources

2023-08-10T01:54:35+00:00

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 [...]

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 [...]

In this article, we will guide you through the process of setting up a CloudFront Function for your CloudFront distribution. We'll walk you through a scenario where we use CloudFront Functions to redirect users to different content based on their device type. By the end of this guide, you'll gain a clear understanding of how CloudFront Functions can benefit your specific use case. Creating an S3  Bucket This bucket will simply serve as a mock origin for the CloudFront distribution that we'll be creating. If you have some test buckets lying around, you may use them instead and skip this [...]

AWS Lambda Response Streaming Demo

2023-07-13T20:17:08+00:00

Introduction Response streaming is a new invocation method that enables your functions to progressively stream response payloads back to the clients. Instead of waiting for the entire data to be ready, your applications can now receive chunks of data as soon as they become available. This means faster loading times and a more responsive user experience. Response Streaming vs. Non-Streaming (Buffering) To quickly get an idea of how it works, we need to see it in action. Below, we show two functions that have the simple task of displaying a message in HTML. The non-streaming function introduces a delay of [...]
