Scalable & Secure Backend Development


In backend development, backend developers create the core computational logic of a website, application, software or information system. All the processes we see in the user interface is developed in backend process. The user can’t see the process but it runs in the background of the application. To put it another way, the back-end makes its entrance into the app in order to give life to the front-end. The other half of it is Frontend development.

Backend Developer aka Programmer or Web developer works on the three main functions of the backend, that is-

  • A server
  • An application
  • A database

In the Backend Development process, the structure is prepared for some key functions such as-

  • Communication between database and app
  • Creating the logical part of the sitemap
  • Backend process of an application that will run on the server
  • Creating a proper line of communication between database, server, and application

The backend of an application is responsible for things like calculations, business logic, database interactions, and performance. Most of the code that is required to make an application work will be done on the backend. Backend code is run on the server, as opposed to the client. This means that backend developers not only need to understand programming languages and databases, but they must have an understanding of server architecture as well. If an application is slow, crashes often, or constantly throws errors at users, it’s likely because of backend problems.

Backend Security

Backend security is one of the major topics of concern these days. The fight is over data as many individuals and competitors want the valuable content to get a boom in their business. There have been many victims of a cyber attack and the list is huge. The thing they had in common was that their application security did not meet the standards and guidelines. Also, the traditional firewalls and anti-viruses only work on the known threats and threat actors and that’s why are unable to stop day-zero attacks.

Keeping data thieves away from your servers and databases is, perhaps, the most important step you can take toward securing the privacy of your employees, your customers, and sensitive corporate information. Without the proper backend infrastructure and security, you could be at immediate risk of incurring a major cyber-attack.

Data issues are further divided into 4 part

  • Data integrity
  • Data-stealing
  • Data loss data location
  • Data location

The Open Web Application Security Project (OWASP) is a non-profit organization devoted to providing practical information about application security. The OWASP Top 10 is a list of the most critical security flaws and provides development teams with a clear set of priorities when it comes to web application security standards. These flaws are widely accepted to be the most exploited vulnerabilities, and remediating them is the first and most important step in decreasing the risk of a security breach.

According to OWASP top 10 guidelines includes:

  • Injection
  • Broken Authentication and Session Management
  • Cross Site Scripting
  • Insecure Direct Object References
  • Security Misconfiguration
  • Sensitive Data Exposure
  • Missing Function Level Access Control
  • Cross-Site Request Forgery (CSRF)
  • Using Components with Known Vulnerabilities
  • Unvalidated Redirects and Forwards

Even as security breaches dominate the headlines, many applications today continue to be released with OWASP Top 10 vulnerabilities. The key to eliminating these flaws is to integrate web application security standards into the entire software development lifecycle (SDLC), rather than simply performing a one-time scan or penetration test after the software has been written.

Backend Scalability

When developing the first version of an application, we often do not have any scalability issues. Moreover, using a distributed architecture slows down development. This can be a major problem for startups whose biggest challenge is to rapidly evolve the business model and reduce market time. While working in backend development we need to keep some key points in mind to make the project scalable. Figuratively we have narrowed the list to 5 important points:

  • API development should be distributed: The system should be designed in a way such that multiple teams can work on it simultaneously and a single team should not become a bottleneck nor does it needs to have expertise on the entire application to create optimized endpoints
  • Support multiple languages: In order to take advantage of emerging technologies every functional part of the system should be able to support the preferred language of choice for that functionality
  • Minimize latency: Any architecture that we propose should always try to minimize the client’s response time
  • Minimize deployment risks: Different functional components of the system should be able to deploy separately with minimal coordination
  • Minimize hardware footprint: The system should try to optimize the amount of hardware used and should be horizontally scalable

Programming Languages

In backend development, we are more focused on the speed and responsiveness of the software. Through these given technologies like JAVA, PHP, and etc we develop dynamic websites or application instead, that helps to store information in the database. In which we keep updating the page, the content is constantly updating.  Here at Think Future Technologies, we take the following criteria into account before choosing the language for the project.

  • Product friendly
  • Scalability
  • Interoperability
  • Security
  • Interconnectivity
  • Structure
  • Interchangeability
  • Robustness
  • Speed
  • Responsiveness

Development teams at TFT adhere to web application security standards and quickly identifying and remediating application security flaws. We also concentrate on the scalability factor of a business and hence make programs flexible which can be adjusted from a thousand audiences to 1 million audiences with ease and minimum risk.
