AWS Lambda, CloudFlare Workers, Deno Deploy Explained

Cloudflare workers run on the edge. They are distributed by default.

For cloudflare workers main usp is their ability to talk to cache and the workers kv. That makes it sort of a programmable gateway to your origin. As the workers run on edge, you could offload tasks like user authentication, mtls validation, session management, immediate data passing, generating signed urls etc.

As you can tap the cache, this lets us save responses for post requests(not possible in the main cdn) at the edge and use it as an entry point for users. I'd say, we should not look at it in the way we look at general nodejs environments. I had to learn it the hard way.

Durable objects looks very promising and it supports long lived persistent connections. But it has its own problems. If done correctly, that would be a game changer for many industrial and retail use cases. But we will have to see how it goes.

Just OWSM. I was reading this term "ServerLess" everywhere nowadays and you made it pretty clear!! Thank you 🤘

Yo codedamn ! Don't stop at any point, you are like a light for me in the dark <3

[hussnainjavd]

You're doing great job to explain the things actual work parallel in different engines

[pjagannadham]

I am new to full stack development but I don't anything about it but I like way of teaching and spreading information with free of cost 😍😍

[pandabro]

Videos from your channel are attracting me and making me know different things. Thank you!

[pjagannadham]

You are providing free full stack development course for free thank you bro

Didn't know much about cloudflare workers. Good to learn about new stuff

[amanagarwal]

Suggestion:
Try to divide the lambda function into DB-related and non-DB function.
Now for example
U can enqueue a message in SQS, dequeue it to a cloudflare worker and perform the non-DB component. Again enqueue the message to another SQS and u can deploy a microservice just for DB operations.
A bit complicated but it should work.

Very Interesting to Watch & Learn something New Daily.. Thanks Mehul Sir 😊🙏🏻

So what’s the use case for cloud flare worker if it can’t connect to a database? That seems pointless to use if it can’t connect to anything. I’m guessing they force your hand to use a database as a service via http calls?

Much needed video..
Thank u codedamn for the amazing content ✨

[parthkumarbera]

Cloudflare workers seems very suitable for cases where you have to run some business logic before passing the event/request to some 3rd party api. Good stuff on your channel 👍

[SRPPixels]

Really man your videos are Highly industry useful and must follow channel if you're a developer. 😍
