Serverless Architecture: What It Is & How It Works
Published: 2024-02-09 14:50:37


![Serverless Architecture: What It Is & How It Works](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/nqp140dwqgr5pthiglci.jpg)

In the realm of contemporary application development, serverless architecture emerges as a beacon of innovation, freeing developers from the cumbersome responsibilities of server management. The days of provisioning servers, grappling with scaling issues, and maintaining infrastructure headaches are a thing of the past. Instead, serverless architecture ushers in a new era where developers can focus exclusively on coding and deployment, while the cloud provider seamlessly handles the backend operations.

At its core, serverless architecture revolves around Functions-as-a-Service (FaaS), where applications are deconstructed into small, independent functions triggered by various events such as API calls, database updates, or scheduled tasks. Developers craft these functions without the burden of managing servers, as the cloud provider dynamically allocates resources, scaling the application as needed while adhering to a pay-per-use model.

The advantages of serverless architecture are numerous. It simplifies complexity by eliminating the challenges of server management, fosters agility through swift deployment and iteration, and ensures scalability and cost-effectiveness through automated scaling and usage-based billing. Additionally, serverless architecture boasts high availability, fault tolerance, and seamless integration with other cloud services, further enhancing its appeal to developers and businesses.

However, serverless architecture requires an understanding of key concepts such as event triggers, statelessness, auto-scaling, and concurrency limits to be leveraged effectively. Moreover, comprehending the distinctions between serverless and containerized architectures (FaaS vs. PaaS) is essential for making informed architectural decisions based on specific project requirements and priorities.

For developers and businesses seeking rapid development, event-driven applications, cost-effectiveness, or reduced operational overhead, serverless architecture presents an enticing proposition. With a plethora of tools and platforms available, ranging from AWS Lambda to OpenFaaS, developers have ample resources to embark on their serverless journey, building modern, scalable, and future-proof applications.

In summary, serverless architecture marks a significant shift in application development, offering unmatched advantages in agility, scalability, and cost-effectiveness. Embracing serverless empowers developers to innovate and deliver robust solutions in today's fast-paced digital landscape, unlocking a world of possibilities for building the next generation of applications.
Angular v17 and SSR, is it really necessary?
Published: 2024-02-09 14:45:06

Hi guys, I have just come to state where I have nearly all new features of new Angular 17 except SSR. So I was like watching a lot of videos and read a lot of articles how cool it is regarding to mainly SEO and maybe other things but I am not sure it this is so cool as for implementation and whole process of set up vs classic SPA application.

The problem I have to accept is that we now have like two bundles. **Client bundle and server bundle** and server bundle includes the server-side rendering logic, the Express server, and the Angular application code that runs on the server. But the issue is that to deploy our angular we need now to deploy it to hosting as usual this is for client bundle but we have another thing to deal with and this is that **to deploy the contents of the dist/server directory to a Node.js server (such as a cloud server, a VPS, or a dedicated server).**

So like life from my opinion is really easy not counting SSR where we have like angular only on client side on hosting and on VPS server we have like really backend services APIs. But with SSR now we have to deal with installing Node.js on our VPS, then deploy there our server bundle and no matter all other stuff regarding linux set up for now server running.

**My question is to all of you who know angular and use it and have experience, what do you thing about it. Is it really something so must have that you are willing to overcome all such things like another server running etc. just for better SEO?**

_I just want to have/see your opinion how you see this and to maybe change my mind ;-)_

Thanks

Cloudflare Workers: Unpacking My Fundamental Misunderstanding
Tags: webdev, serverless, javascript, cloudflare
Published: 2024-02-09 13:49:09

I’ve fundamentally misunderstood how Cloudflare Workers work.

While setting up Sentry for my [Notion<=>Google Tasks](https://notion-google-tasks-sync.com/) integration app, I noticed that a single Issue in Sentry contained data (”breadcrumbs”) from different requests to the Cloudflare Worker. This was a startling discovery indicating a data leak between Workers requests.

That implied either of two things:

- Cloudflare has a bug in their “beta” [Queues Workers](https://developers.cloudflare.com/queues/) product
- My fundamental knowledge and assumptions about Cloudflare Workers have been wrong for years since their introduction.

After a brief conversation in their Discord channel and with the Director of Product for Cloudflare Workers, I learnt that my understanding had been wrong.

I had believed that every Worker invocation is executed in a completely isolated environment, with a new V8 isolate created for each call and discarded right after the call is finished. This assumption led me to think that there was no need to worry about possible data leaks between calls, a problem inherent in most (all?) serverless platforms. This feature was one of the primary reasons I was excited about Workers.

However, the reality is that Workers isolates are actually shared between calls, which explains why a single exception in Sentry contained data from multiple calls.

Where did I get such misunderstanding from?

Part of the blame lies with Cloudflare’s [How Workers works](https://developers.cloudflare.com/workers/reference/how-workers-works/) page, which, up to this day, has contained a wrong statement:

> “Workers processes are able to run essentially limitless scripts with almost no individual overhead by creating an isolate for each Workers function call”.

![An excerpt from Cloudflare's "How Workers works" page with the highlighted words "creating an isolate for each Workers function call"](https://dev-to-uploads.s3.amazonaws.com/uploads/articles/akzy5r3bj3s1zysicrqf.png)



I have created an [issue](https://github.com/cloudflare/cloudflare-docs/issues/12885) in their docs repository to address that misleading statement.

The other part of the blame is on me for not thoroughly reading that page from top to bottom, failing to spot the contradiction and not validating my assumptions.

That revelation makes me to rethink my approach to building Workers apps.
How do I host the MTA-STS Policy URL on IIS?

A long while has been trapped on Mainkya Chaypa during the configuration of the MTA-STS Policy File for seosiri.com on IIS and the only problem is with URL Path after the .well-known folder.

Wrong URL - https://mta-sts.seosiri.com/.well-knownmta-sts.txt
Desired URL - https://mta-sts.seosiri.com/.well-known/mta-sts.txt

Seeking support to host the MTA-STS Policy URL on IIS for the Desired URL - https://mta-sts.seosiri.com/.well-known/mta-sts.txt
