CDN (Content Delivery Network)

CDN is a computer networked system that connects to each other over the Internet and delivers music, pictures, videos, applications, and other files to users faster and more reliably with the server closest to each user.

What is CDN?

With the development of internet, users pay more and more attention to the browsing and effects of websites when using internet.However due to of the surging number of internet users and long routes of network access, the quality of users access is severly affected. Especially when the link between user and the website is bursted by large traffic data. poor quality of access is an urgent problem to be solved in areas where number of users in remote areas is rapidly increasing. How can we make high quality to users everywhere and minimize the resulting costs and pressure on web site management? Content Develivery Network was born.

Configuring Android Studio with Kotlin

Bhavdip

Which is a new programming language that is a pragmatic, safe,concise, and interoperable alternative to Java.With Kotlin, you can implement your projects with less code, a higher level of abstraction, and fewer annoyances

Kotlin is concise, safe, pragmatic, and focused on interoperability with Java code. It can be used almost everywhere Java is used today - for server-side development,Android apps, and much more. Kotlin works great with all existing Java libraries and frameworks and runs with the same level of performance as Java.

This allows for shorter code and greater flexibility in creating data structures.But the downside is that problems like misspelled names can’t be detected during compilation and lead to runtime errors.

The ability of the compiler to determine types from context is called type inference.

Performance - Calling methods is faster because there’s no need to figure out at runtime which method needs to be called.

We need the server or machine where our web application is running. That usually provide us IP and we access it from internet. 

Now issue of that approch is that server has to be up all time in anycase even if your user traffic is increase or decrease.

On our end if we don't get enough traffic still we have to pay for basic provision and manages charge for run it.

Along with that we need to manage the server upgrade the software, os should up to date.

In this idea, we can run our application without actual manages the resources.
