In this video tutorial you will understand the basics of CAP theorem in simple terms. A simple explanation has been provided with a couple of examples.
CAP theorem is used to make tradeoffs between consistency and availability in distributed systems.
Astro is one of the most notable projects of the year. Astro is a tool to build web sites that load faster because they ship less JavaScript.

How can you build a faster website?
To build a faster website you need to ship less code. Astro is a kind of static site builder that delivers lightning-fast performance with a modern developer experience.
With Astro you can build your site using your own framework like React, Vue or just HTML and JavaScript. Astro then renders the entire page to static HTML, removing all JavaScript from your final build by default.
If there is a real need for some Javscript component, Astro loads it when it’s visible.
It supports all the npm packages, CSS modules etc and is SEO enabled.
How it works?
Astro works like a static site generator which means it will generate a static HTML site for you during build, with almost no Javascript. It’s pretty obvious that this will be much faster compared to a site with Javascript.
When a component, like add to cart or carousel, needs some JavaScript, it loads that component. The rest of your site continues to exist as static, lightweight HTML. This new approach to web architecture is called islands architecture.

Sunny owns a bookshop, which is doing reasonably well, and he wants to offer his services online via an e-commerce website. He starts to do some research on how to build a website.
After few days of searching and reading blogs he puts down his options.

2. Use a website builder and try to create a website on his own with some help from a freelancer, which may cost him less.
3. Learn programming and start building a website from scratch.
In your view which approach makes sense?

What are Distributed Systems?
In this article I will try to explain distributed systems in simple words. So that you can understand what they are and how they can help.
At a high level distributed systems are a group of computers working together towards a common goal. For an end user or client it’s just one computer. But behind the scenes the work gets distributed among a set of computers or servers.
