Core Languages

Different core programming languages needs different considerations during development phase. For example, Python code is organized into well-defined modules and packages for better readability. Use exception for graceful handling of errors.
While using C code, we carefully consider the pointer arithmetic and memory management. Object-oriented programming our focus is object inheritance and run-time polymorphism, which needs special attention.



Middle-ware

We consider this as a main business logic layer which considers security (data-at-rest & data-at-transit) and scalability (horizontal and vertical) during its design. Monitoring and logging features are also implemented to trace KPIs (response time, throughput, CPU, Disk, memory, error rate)
We design this layer as service-based architecture having well defined restful API, interface with databases and integration with distributed entities.



Web Servers

The security of websever is highly important aspect, protecting business data from malicious users and building trust. It is recommended to use access-control list, controlled SSH without sudo access. We have implemented SSL/TLS certificates using Let's-Encrypt for communication.
