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 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...?

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);
};

Thank you very much!
