exe.dev: a new hosting solution for your prototypes

Bite code! • 1223 implied HN points • 17 Feb 26
🕹 Technology Containers
  1. exe.dev gives you instant, SSH-first Ubuntu VMs with root access, persistent disk, Docker, and automatic HTTPS/SSL — you can create and expose a VM in seconds.
  2. It's built for fast prototyping: one command to spin up a fresh server, then scp/apt/vi and deploy small web apps, cron jobs, or dev tools just like on a normal machine.
  3. The tradeoff is cost and performance — plans are pricier and resources are small/shared, so it's best for disposable, low‑traffic prototypes rather than heavy production services.

Issue #113

Infra Weekly Newsletter • 13 implied HN points • 09 Dec 25
🕹 Technology Containers
  1. Ingress NGINX is being retired in favor of the Gateway API, so teams should plan and follow migration steps to switch to API Gateway.
  2. Infrastructure-as-Code best practices emphasize modular design, testing, and isolating dependencies; they also recommend safe update patterns like blue‑green deployments, cross-team collaboration, and secure, scalable provisioning.
  3. Linux 6.18 is the new LTS kernel and distributions like Alpine 3.23 are adopting it quickly, so operators should plan OS/kernel upgrades and test their stacks against this LTS.

🕹 Technology Containers
  1. AI-powered agents are starting to automate DevOps and SecOps by turning natural language into configs, deployments, and monitoring while following best-practice frameworks.
  2. Kubernetes has become the dominant platform for running infrastructure and workloads, effectively serving the ecosystem role Linux once did and spawning tooling like Karpenter to manage resources.
  3. Metal³ together with Ironic brings Kubernetes-style, declarative management to bare-metal servers so you can represent hosts as Kubernetes resources and automate provisioning, and Metal³ is now a CNCF incubating project.

🕹 Technology Containers
  1. Debian riscv64 is now an official architecture
  2. Phoenix's hot and dry climate raises questions about building data centers there
  3. AWS introduced Seekable OCI technology for faster container launches

Some practical tasks with k8s Pods

DevCube • 2 HN points • 26 Feb 23
🕹 Technology Containers
  1. When working with microservices and Kubernetes, it's important to remember basic tasks like troubleshooting Pod startup and accessing logs.
  2. Don't solely rely on different tools for Kubernetes tasks, remember the fundamental basics.
  3. Appreciate foundational explanations like Liz Rice's video on containers, even if they are older, for understanding container technology.

Issue #71

🕹 Technology Containers
  1. DoltgreSQL is a wire-compatible PostgreSQL with versioning, similar to using Git.
  2. Charm is admired in the Go community for crafting valuable Go-powered utilities and command-line interface libraries.
  3. IAM Access Analyzer and IAM action last accessed can refine permissions for AWS IAM roles across different accounts.

The Moving Target: Open Source Release of Phoenix

Phoenix Substack • 0 implied HN points • 17 Mar 26
🕹 Technology Containers
  1. Reactive detection and simple deception aren’t enough; if your infrastructure stays put attackers can exploit it before you notice.
  2. Phoenix implements Automated Moving Target Defense for Kubernetes by proactively moving pods, rotating identities, and reducing attacker dwell time so exploits matter less.
  3. The open-source operator gives a solid baseline for most teams, while a closed-source version adds granular policies, specialized AI/NVIDIA support, and faster predictive logic for large or regulated environments.

The Nextjs that runs on Vercel is not the same that runs on your infrastructure

Microfrontends, Architecture and Trade-offs • 0 implied HN points • 03 Jan 24
🕹 Technology Containers
  1. When using modern frameworks like NextJS or Remix, running on serverless infrastructure is common and efficient.
  2. Deploying a NextJS app on Vercel leverages serverless/edge functions, leading to better scaling without nodejs event loop limitations.
  3. For more control and customization, consider options like deploying NextJS in a containerized, auto-scalable environment or creating a custom framework using vite-plugin-ssr.

Redis-driven Dataflow for Clickstream Aggregation

Bytewax • 0 implied HN points • 19 Oct 23
🕹 Technology Containers
  1. Bytewax framework strikes a balance between being user-friendly without hiding underlying mechanisms.
  2. When writing custom connectors with Bytewax, focus on transforming messages in the `next_batch` method and delegate other processing to the dataflow.
  3. Consider the partitioned nature of inputs and utilize `list_parts` and `build_part` methods for handling multiple data streams in Bytewax.

Building DroneCI Pipelines

Certo Modo • 0 implied HN points • 14 Nov 23
🕹 Technology Containers
  1. Each pipeline step in DroneCI can use different container images, allowing for versatile tasks like testing across multiple platforms.
  2. Base64 encoding secrets in DroneCI is a useful technique for securely handling sensitive information like SSH keys.
  3. Monitoring DroneCI pipelines can be enhanced by utilizing Prometheus to track status, duration, and using a Push Gateway to export build metrics.

Routing 101 Part 1

Paul’s Substack • 0 implied HN points • 27 Jun 24
🕹 Technology Containers
  1. Routing involves sending messages between components like parent and child containers.
  2. Basic routing includes sending messages down from parent to child, across between children, and up from child to parent.
  3. Consider factors like multiple output messages, multiple inputs and outputs, and different routing scenarios when designing a routing system.

Shipping Fast with FastAPI and Cloud Run

realkinetic • 0 implied HN points • 28 May 24
🕹 Technology Containers
  1. Building APIs with FastAPI and deploying them on Cloud Run can help you ship features quickly while maintaining enterprise standards and leveraging cloud resources.
  2. To ship a backend API using FastAPI and Cloud Run, you will need to work with Python >= 3.10, Google Cloud services, Docker for containerization, and establish logging, monitoring, and testing strategies.
  3. By combining FastAPI for API development, Firestore for database interaction, and Cloud Run for deployment, you can create a robust backend system that can be efficiently tested, deployed, and managed in the cloud.

There and Back Again: Why PaaS Is Passé (And Why It’s Not)

realkinetic • 0 implied HN points • 06 Feb 18
🕹 Technology Containers
  1. In the world of cloud computing, PaaS (Platform as a Service) has lost some of its appeal due to concerns like vendor lock-in and limitations.
  2. The cloud landscape is complex and evolving rapidly, with tools like Kubernetes and serverless reshaping how applications are developed and managed.
  3. Major cloud providers are moving towards unbundling and rebundling PaaS components to offer the benefits of accelerated development while retaining flexibility.
