The Architecture Of A Web Application Built Using Linux

From transforming communication channels to offering breathtaking customer experiences, web applications have overhauled traditional business models. To keep up with the technology, developers across the globe are looking for solutions to build, deploy, and scale applications quickly without having to develop and maintain operating systems and web servers.

For instance, the AWS delivers and hosts more than 1 million cloud-driven applications. It uses powerful features such as integrated CI/CD and deployment slots. So, developers can deliver applications to the end users in a way that’s faster and user-friendly. Linux denotes a group of free and open-source operating systems that are developed around the Linux Kernel. Web developers with Linux skills in New York are drawing an annual pay in excess of US$75,000. Therefore, it certainly won’t be a hyperbole to state that learning Linux can propel an aspiring developer’s dream of making it big in the industry.

Linux Kubernetes fundamentals answer all your questions regarding the deployment, management, and scaling of applications that are containerized.

What is Kubernetes?

It is an open-source system that helps to scale, manage, and deploy applications that are containerized. It was developed by Google and was donated to the Cloud Native Computing Foundation.

The architecture of a web application involves the following components:

Resource Group

It is a logical container for resources of Azure.

API App And A Web App

A contemporary application can include a website as well as a RESTful web API. It can be used by clients of the browser through a set of web development techniques called AJAX.

Webjob

WebJobs can be used to run long-running tasks in the background.  These can be pre-scheduled or can be deployed in response to a trigger. They run as a background process in the context of an App Service app.

Queue

The background tasks are queued by application queues by putting a message onto an Azure storage queue. The message triggers a function in the webJob.

Cache

They are used to store semi-static data.

Content Delivery Networks

These help to cache content available in the public domain. It enables content to be delivered quickly while ensuring lower latency.

Data Storage

Use Azure SQL database while dealing with relational data. For data that's non-relational, use NoSQL store.

Search

It can be used to add search functionality in the form of search suggestions and language specific search. It can also be used together with other data store.

Email

Use a third-party service such as Twilio and SendGrid to send emails or SMS instead of directly incorporating this feature into the application.

Dns Domains

It is a hosting service meant for domains of the DNS. It gives a name resolution using Microsoft’s infrastructure named Azure. By hosting your domains here, a user can manage his DNS records using the same set of credentials, APIs, tools, and billing just as other services of Azure.

A large number of programming languages support Linux. These languages can be used to build scalable web applications. The languages are:  

PHP

It is an object-oriented programming language used for building dynamic webpages and websites. It is quite frequently compared to ASP.Net by Microsoft with a striking difference being its ability to run on several web servers. WordPress, a popular blogging website has been built using PHP.

Python

Python is an advanced programming language built for undertaking general programming.  It was developed by Guido van Rossum, a Dutch programmer, in 1991. Python is based on design philosophy and focuses on the readability of the code. It follows a syntax which allows programmers to design concepts using just a few lines of code. It also provides constructs for clear and hassle-free programming on large as well as small scales.

Python is considered a versatile programming language. It can be learned by those who are fond of building basic video games. It can further be used to test microchips and desktop apps. Used frequently by programmers across the world, Python is one of the easiest programming languages one can get to learn. It is an ideal starting point for beginners. The fact that the likes of popular search engines such as Google and Yahoo have been built using Python speaks volumes about the language’s popularity.

.Net

It provides a set of tools to run a code written in .Net. These tools are compliant with the ECMA International Standard and can run on several platforms. These mono tools are being developed heavily and their latest version provides the core API of the .NET framework (version 2.0). It also has a Visual Basic component that allows VB apps to run under Linux.

The rising popularity of Kubernetes is quickly making it a preferred standard to operate various containerized applications at huge scale in the datacenter. Aspiring developers and programmers can learn the fundamentals of Kubernetes with QuickStart.
