Great article which shows difference between service meshes and their usage in kubernetes ecosystem https://lnkd.in/gwWj-Vdd

Dapr was born to help application developers, the silent majority of the cloud-native ecosystem, to tackle the increasing fragmentation in developer tooling, cloud platforms and infrastructure services. This fragmentation forces developers to become experts of everything and spend precious time plumbing things together, leading to unreliable and increasingly vulnerable systems. Dapr has grown to be one of the largest CNCF OSS projects with a community of over 3,000 developer and thousands of end users. Today, I'm incredibly excited to announce the next step of this journey with Diagrid Catalyst - developer APIs for creating workflow orchestrations with durable executions, event-meshes, state management and much more, all based on the Dapr APIs and running as a fully managed service in your cloud of choice. Developers can use Catalyst with their existing infrastructure and securely call the APIs from any compute service in every public cloud or edge platform. With Catalyst we are also announcing two serverless offerings: A pub/sub broker and key/value store, accessible by the Dapr-compliant Catalyst APIs with built-in security, circuit breakers, retries, access policies and much more. We are now onboarding a limited number of developers for a free early access program. Read the announcement and sign up here: https://lnkd.in/gmVt6pSs

Here is how API gateways became "monsters" of the modern software development. In my honest opinion, rather than adopting such convoluted approach, I would rather prefer a more message bus oriented approach. Moreover, investing in "inventing" so many object classes just for an API gateway seems like an overkill for many of the K8S applications. https://lnkd.in/dWg6HHzX #k8s #gateway #decoupling #neutrality

Most people don't know that Stateful Persistent storage services are completely missing in Kubernetes by default. You don't get it, & storage is ephemeral by default. That's not viable for Mission critical Enterprise apps. - The main Kubernetes Wikipedia page highlights this pain-point and spotlights our product; OpenEBS as the #1 most evaluated & deployed Persistent Storage service for K8s. We've held the #1 rank for more than 4 years! https://lnkd.in/gwyFWgfH

It's quite fascinating how the tides of technology ebb and flow, much like a pendulum swinging between trends. Once again, we find ourselves revisiting the concept of vertical scaling. 😂 However, this isn't your OG vertical scaling; it's fancy, it's rightsizing for optimal performance AND cost efficiency. And yeah, dude, we will have "in-place" action at the container level soon! 😬 The beauty of VPA lies in its adaptability; you have the power to configure it as either a wise recommender or an active agent in the resource optimization process, offering a level of customization that sets it apart in the Kubernetes ecosystem. 👾 So, what is Kubernetes Vertical Pod Autoscaling (VPA)? VPA in Kubernetes automates the process of adjusting the CPU and memory resources required for pods. Unlike HPA, which focuses on increasing or decreasing the number of pods, VPA adjusts the resources of individual pods. 👾How Does VPA Work? VPA operates by monitoring the resource consumption of pods and automatically adjusting their CPU and memory requests based on usage (if you want). This ensures that pods have enough resources to operate efficiently without over-provisioning, which can lead to unnecessary costs. I mean, we currently rely on Pod termination and Admission Controller webhook hacks to achieve that, but you get the idea, lol. 👾Key Features: - Automatic Resource Adjustment: VPA sets resource requests based on usage, optimizing for both performance and cost. - Compatibility and Installation: Compatible with various Kubernetes versions, VPA can be easily installed in your cluster. - Different Operating Modes: VPA offers several modes, including 'Auto', 'Recreate', 'Initial', and 'Off', providing flexibility in how resources are managed. BUT HOLD YOUR HORSES! 🐎 🛑 👾 (Very important) Considerations and Limitations: - VPA may cause pods to be recreated, which could lead to temporary unavailability. - Using VPA with Horizontal Pod Autoscaler (HPA) on CPU or memory is not recommended, as you don't want them fighting and flapping on top of your workload in Production. (haha, trust me) - VPA's behavior in large clusters has yet to be extensively tested. TBH, HPA covers 99% of my use cases so far. What do you think? Is our tech stack becoming a huge onion? Will our future newbies know cgroups?🤓 https://lnkd.in/d3UKS5eY #kubernetes #cicd #harness #devops #cloud #k8s #cncf #linux #sre #observability #sdlc #gitops #docker #container #certification #cka #kcna

Ahoy! The Cloud Pirate is here to summarise Jack Roper's article on How to Use Kubectl Port-forward in Kubernetes Applications. This article explains how to use kubectl port-forward in Kubernetes to expose ports and access applications running inside the cluster. The author provides a step-by-step guide on how to use kubectl port-forward to forward a container port to a host port and access the application using a web browser. The article also includes some common use cases for kubectl port-forward and tips for troubleshooting. #Kubernetes #Portforwarding #CloudNetworking 💻🏴☠️ #Azure #OpenAI #TheCloudPirate Author: Jack Roper.

CodeDeploy can now call your application’s stop hook during ASG scale-ins so that you can complete ongoing tasks, release application resources, or close outgoing connections. Your application’s stop hooks can also be invoked during ASG instance refresh operations, allowing you to patch your instances without impacting your application’s availability.
