Because Django was developed in a fast-paced newsroom environment, it was designed to make common Web-development tasks fast and easy.

High-level Python Web Framework

Security is matter

Core security features of Django

00

Cross site scripting (XSS) protection

01

Cross site request forgery (CSRF) protection

02

SQL injection protection

03

SSL/HTTPS

04

Host header validation

05

Referrer policy

06

Session security

Django is as secure as any web framework can be. It provides tools and doc to prevent common mistakes causing security problems (csrf, xss, etc.) However, a tool in itself cannot be "secure". The whole platform security depends on the proper use of the tools you choose, and thus is more a matter of developer skills.

PERFORMANCE & OPTIMIZATION

PERFORMANCE & OPTIMIZATION

We strongly advocate betting on the high performance of Python - combined with the Django framework - for so many different projects. But even within this powerful combination, there is always room for improvement.

Django, along with python, provides a high-performance web application.
But we can further optimize the Django Performance based web application by implementing these methods...

How We Further Optimize Our Django Apps

Django, along with python, provides a high-performance web application.
But we can further optimize the Django Performance based web application by implementing these methods...


Caching

Avoids Computation

It may be a good idea to save if you're visiting the same site repeatedly, so that we don't have to recompute every time clients request for it.

This is a powerful method that can provide a huge benefit if serving a large number of requests.

High-Performance Django has a strong cache framework for storing dynamic content so you don't have to compute it again and again. Gives you grain options for caching the entire page or some selected pieces or special effects.

Laziness

Avoids Computation

Laziness eliminates calculations in the first place and can only be done when needed. This will help us to calculate this previously calculated value, and we will save this calculation.

Laziness and Caching go hand-in-hand

Operations like querySets in the high-performance Django are lazy. Because querySets does not take information/data when creating, editing, or merging. Only when the values ​​in QuerySets are used, those values ​​are extracted from the database.

Database Optimization

One of the main reasons for delaying the performance of web applications is the requested queries on the database. Therefore, the database's functions and queries must be formatted in order for them to function optimally.

With SQL, you need to take care of specific database queries like 1Accumulated views, 2Database triggers, 3Tasks / Functions, 4Stored processes.

If you take all the information/data you need in one query, the database system can be optimized. QuerySets are lazy and only provide the required information, which can lead to a lot of operations on the database during the operation.

HTTP Performance

Django middleware ConditionalGetMiddleware and GzipMiddleware are used to increase/improve the performance of requests which the website receives everytime.

ConditionalGetMiddleware conditionally adds Etag and Last-Modifier headers to the requests to enhances the performance. And the request has If-None-Match or If-Modified-Since, the response is replaced by an HttpResponseNotModified.

The GzipMiddleware zips all the responses from the browsers that understand gzip compression. You should add this middleware once the response is completely formed and all headers are added.

Yet, GzipMiddleware is considered a security threat currently by the security experts. So, make sure you use it with caution.

Sessions

order to optimize performance

Cached sessions can be stored in order to optimize performance. The cached Session will help to bring down the number of times a system tries to reach the database. The cached Session will save the information in itself.

You can also save the sessions in cookies. The session saved in the cookies is encrypted using the SECRET_KEY and you should make sure attackers should not get access to SECRET_KEY otherwise they may read the session data and execute code remotely.

Code Optimization

It is important that you optimize your domain logic code so that it does not take a lot of time to execute.

There are three prominent ways to lift the efficiency of the code:

  • Upgrading the third-party packages
  • Simplifying the code
  • Restructuring the code
    • Django for scalable websites

    SCALABLE WEBS

    Flexibility
    Reliability
    Scalability

    Django is distinguished mainly by its simplicity, flexibility, reliability, and scalability.

    Django is definitely an extremely scalable and well thought out framework. The opinionated design of Django allows us for fast development, and it allows Django to give us the tools needed to build a great application out of the box.

    Thanks to the architecture based on the MVT pattern, pages made in Django scale very easily and quickly. The framework clearly separates different parts of the architecture from each other and, as a result, each part is independent of the others, which significantly facilitates the scaling process and development. It is very easy to add various servers such as cache servers, database servers, or application servers. Scaling a website is primarily aimed at meeting the increasing requirements resulting from the growing traffic on the website.

    Django can run with any platform once it done

    Multiplatform

    Multiplatform Django applications and websites work on multiple platforms such as Windows, Linux, and Mac OS. This means that any application written in one operating system can work on another system without major problems.

    Limitations of Django

    Using django have a bit disadvantages

    Lack of convention

    In comparison to other frameworks like Ruby on Rails , Django doesn’t have an established specific code of conduct, that developers follow when creating websites. In Django, every object has to be defined and configured with the rest. As work progresses, more and more components need to be defined and configured. As a result, the lack of convention slows down the development of a technological solution.

    Monolithic

    Django is very monolithic, which means it has a small number of dependencies. The smaller the number of dependencies, the more code has to be written by the developer. Additionally, many developers mistakenly assume that Django is a single package to build a website.

    Not suitable for small projects

    Django was designed with large and scalable projects in mind, so it is not the best solution for simple and small projects. Due to its structure, specificity, and many functions necessary in complex projects, creating small websites in Django is relatively difficult and time-consuming. In the case of a small project, it is advised to use a framework other less demanding than Django.
