firebaseui-web VS aws-lambda-java-libs

One great product that can be used for authentication is Clerk but we currently use the default Firebase authentication system as it works pretty well. Firebase even has a separate package called firebaseui-web that helps one set up Firebase authentication without writing any UI code.

In this example, you can see how flexible and customizable the library is. For full documentation, you can see the github repository page here.

Firebase authentication allows for the complete customization of the entire authentication experience for beginners with speed and ease. Nobody sets out to build a bespoke authentication solution unless your business is identity like Auth0. Firebase authentication provides an open-source user interface (UI) library which streamlines building diverse authentication flows for a great user experience. These flows come with the wisdom of years of UX research optimizing the authentication on Google, Youtube, and Android to get you started.

SvelteKit, Serverless, Backendless.com

SvelteKit[1] is a framework for SvelteJS (like Next.js is a framework for ReactJS). I've tried both Svelte and React. Svelte seems to be more elegant and lets me implement my ideas faster with less code. Svelte is very flexible; SvelteKit adds some opinions on how to do things like routing.

SvelteKit also embraces the serverless paradigm[2] (AKA JAMstack[3]). Although a node.js server is still an option, you can also have pages rendered in serverless functions or pre-rendered at build time. Even static pages can be "hydrated" on the client so they are not totally static. So this results in fine-grained SSR (server-side rendering) at the page level. The two main reasons for SSR are performance (especially on mobile devices) and SEO.

Backendless[4] is a VADP/MBaaS. This platform offers a lot of services, but the main one I'm looking at is authentication/identity. I was looking for an authentication service that supports anonymous guest login, social login, as well as traditional email/password login. The other contenders were Google Firebase (slow, and confusing sign in/sign up flow[5]) and AWS Cognito (too complicated/difficult to use). Auth0 was a contender, but they don't support guest logins.

Event Producers: Generate streams of events, which can be implemented using straightforward microservices with AWS Lambda (for serverless computing), Amazon DynamoDB Streams (to captures changes to DynamoDB tables in real-time), Amazon S3 Event Notifications (Notify when certain events occur in S3 buckets) or AWS Fargate (a serverless compute engine for containers).

Amazon Web Services (AWS) Lambda is a serverless function-as-a-service (FaaS) platform that lets you deploy, run, and scale code in the cloud as self-contained functions without having to manually configure any infrastructure. Lambda runs your functions on demand in response to specific events, such as an HTTP request from the internet or activity in another AWS service.

FaaS is specifically focused on building and running applications as a set of independent functions or microservices. Major cloud providers like AWS (Lambda), Microsoft Azure (Functions), and Google Cloud (Cloud Functions) offer FaaS platforms that allow developers to write and deploy individual functions without managing the underlying infrastructure.

So AWS Lambda is basically a serverless computing service that is offered by AWS. It enables developers to run the code in response to various events. It protects the developers from the pain of managing the servers. Using a serverless execution model helps the developers to handle provision, manage and scale the servers automatically. Through this approach the developers can fully focus on writing the code instead of dealing with other aspects.

The first product that popularized the term “serverless” was AWS Lambda, which is both the prototypical and archetypical function as a service provider. It also has a great name, which pings back to its envisioned place in the cloud of the future. In computer programming, a lambda, often referred to as a lambda function or lambda expression, is a concise way to represent an anonymous function, which is a function without a name. The concept originates from lambda calculus in mathematical logic and has been adopted by many programming languages, each with its own syntax and characteristics.

You can build a custom config rules in 2 ways, using AWS Lambda and CloudFormation Guard. Lambda gives you a lot of flexibility, but it also brings complexity of maintaining. CloudFormation Guard is a bit more lightweight in that regard. Yes, you still need to maintain the logic to determine when your resource is compliant or not. But you need to do this in both cases, thus my go to preference is CloudFormation Guard.

AWS Lambda: https://aws.amazon.com/lambda/

This blog details how you can use some key serverless components from AWS like Amazon Eventbridge, AWS Lambda, and Simple Notification Service to setup a system that will monitor your site (which can be running anywhere) and send emails, text messages, slack messages, and more when the reachability status of your site changes.

I use the OpenWeather API to receive the current temperature data by providing the latitude and longitude coordinates as query strings in the request. A Lambda function invokes the weather API and sends the current temperature value as a custom metric to CloudWatch. I then graph the temperature values on a dashboard and activate an alarm when the temperature sinks below zero degrees Celsius.
