A brief story about infraestructure

Managed by 3rd parties

VPS, Containers...

The Cloud was born

Cloud Benefits

  • Better security
  • Recoverability
  • Lower costs
  • Less responsibility

ฦ’(state) + ฦ’(state) + ... = app

Things that changed

  • How we organize the code
  • How teams organize
  • How we deploy the code
  • How the code runs

Serverless

Serverless Benefits

  • Lower costsย 
  • Simplified scalabilityย 
  • Simplified backend code
  • Quicker deployments

Huge evolution milestone

Single region!

Edge Benefits

  • Lower costsย 
  • Also automatically scalable
  • Deploys globally, low latency
  • Zero cold-start time, better performance (??)
  • Distributed storage

Zero cold-start time

V8 isolates (secure)

Use cases

  • Low latency is important: self-driving cars, games, highly competitive markets
  • Personalization, regional targeting for e-commerce
  • A/B testing
  • Access prevention by location
  • Google Maps example, would show initially the country you visit from

Barcelona

Speed

Comparison with Lambdas

Just as fast?

Edge providers

  • Netlify Edge Functions

  • Akamai Workers

  • Cloudflare Workers

  • Layer0

  • Lambda@edge
  • other CDN companies...?

Closest Point of Presence (POP)ย 

import { IpApiResponse } from '~~/types';

export default defineEventHandler(async () => {
  const key = useRuntimeConfig().API_TOKEN;
  const data: IpApiResponse = await $fetch(
    `https://pro.ip-api.com/json/?key=${key}`
  );
  return data;
});
/server/api/location.ts
import type { Ref } from 'vue';
import type { IpApiResponse } from '@/types';

export const useLocation = () => {
  const location: Ref<IpApiResponse> = ref();

    location.value = await $fetch(`/api/location`);
  });
  return location;

About localization

import type { Ref } from 'vue';

export const useLang: () => Ref<string> = () => {
  if (process.client) {
    return ref(navigator.language);
  }

  const parseLangString: (languages: string) => string = (languages) => {
    return languages.split(',')[0];
  };
  const nuxt = useNuxtApp();
  const lang: string = parseLangString(
    nuxt.ssrContext.event.req.headers['accept-language']
  );
  return ref(lang);
};
