Deployment options and decision criteria
Browser tabs, SEO snippets, OG share cards — the same page often shows three different titles in three places. Cause is straightforward: the title template isn't composed from a single source, and pages also stamp the s…
GitHub Pages turns a GitHub repository into a free static website. It serves plain HTML/CSS/JS or the build output of any static site generator (Jekyll, Hugo, Vite, Astro, …).
Replit puts the IDE, real-time collaboration, deployment, and AI code generation in one URL. No local setup — go from a natural-language prompt to a deployed app in a browser tab. It's one of the flagship products in th…
Some external SaaS providers have no emulator: OAuth login · payments · dynamic DNS · Slack Webhook · AI providers, plus services where the official side never built one, such as Firebase Cloud Messaging. When you want…
After building a container image, the next question is where to run it. One option is to run docker directly on EC2; another is to delegate container lifecycle, health checks, rolling deploys, and service discovery to a…
Whether a subnet is "public" or "private" is decided by routing, not by labels. Once we understand how Internet Gateway (IGW), NAT Gateway, route tables, and VPC endpoints combine, the meaning of subnet design becomes c…
Distributing traffic across backends, removing dead servers, and managing certificates from a single place are common needs across nearly every web service. AWS's seat for this is ELB (Elastic Load Balancing) — four fla…
The single phrase "deploy on AWS" hides choices that span very different abstraction levels. From managing one EC2 box directly all the way to function-level hosting like Lambda. Including other clouds and PaaS, the pic…
S3 (Simple Storage Service) was the first AWS service to reach GA, in 2006, and it popularized the object storage category. Neither file system nor block storage, the model of "an infinitely large bucket accessed by key…
Every cloud call eventually passes through "who · what · where" questions. In AWS, the place that answers them is IAM (Identity and Access Management). Compared with the flashier managed services, IAM has a plain text-p…
A VPC (Virtual Private Cloud) is the virtual network where compute, databases, and load balancers live in AWS. If the shape of the VPC is not defined first, every decision inside it stays unstable.
Operating a relational DB directly is an area heavy with backup, recovery, HA, tuning, and version upgrades. RDS (Relational Database Service) takes a large share of those operational responsibilities off the user's han…
EC2 (Elastic Compute Cloud) is the first compute service AWS released, and it popularized the cloud "virtual machine" abstraction. As managed services have grown, the share of direct usage has diversified, but EC2 remai…
AWS effectively defined the cloud services market. The service catalog tops 200, but at the category level it boils down to a handful of larger groupings.
DNS, which resolves domain names to IPs, is one of the oldest pieces of internet infrastructure. AWS's managed DNS service is Route 53 — named after the standard DNS port (53).
Most of AWS lives in magical data centers across the internet, charging money to do work. To verify on a developer machine, three costs apply daily: (1) creating a PoC account on real AWS, (2) paying somewhere, (3) stal…
There is a model where code runs at the function level without provisioning a server. Compute wakes up when an event arrives, runs the function once, and disappears. AWS's seat for this is Lambda — it played a major rol…
Caching static files, video, and API responses near users speeds up responses and reduces load on the origin server. The service that does this on globally distributed edges is a CDN (Content Delivery Network).
AWS network firewalling has two layers: the Security Group (SG) attached to instances, and the Network ACL (NACL) attached to subnets. The names are similar, but the operating models differ quite a bit.
Supabase appeared in 2020 with the slogan "open source Firebase." If Firebase is one giant managed box with its own NoSQL · Auth · Storage, Supabase took the path of placing Postgres at the center and stacking small com…
Firebase started as a small startup in 2011 and was acquired by Google in 2014. Being a managed-first service, "no way to run it locally" was the right answer for a long time, but in March 2020 the picture changed when…
Fly.io is a PaaS that quickly deploys containers to global edge locations. Internally it converts container images into lightweight Firecracker microVMs.
