NFR consulting, in the context of IT architecture services, refers to addressing non-functional requirements (NFRs) in software development. Non-functional requirements encompass aspects such as performance, security, scalability, reliability, and maintainability, which are crucial for the overall success of software systems. NFR consulting, in the context of IT architecture consulting, involves analyzing, defining, and prioritizing these non-functional requirements to ensure they are effectively incorporated into the software architecture and design.

Performance and Scalability Consulting

As businesses evolve, achieving and maintaining the desired performance becomes a challenge. The growing client base and data size degrade the application's performance. Massive scaling needs and high performance under extreme load are becoming common denominators.

For large-scale companies, even a few milliseconds (ms) of degradation in performance adversely affect revenue. 

Studies show that 40 percent of shoppers will wait up to three seconds before abandoning a retail or travel site. A report by a leading e-commerce website states that every 100-ms increase in the page load time decreased sales by 1 percent, while a leading search engine website stated that a 500-ms increase in the search results display time reduced revenue by 20 percent. Hence, to meet the client's expectations and to stay ahead of the competition, software performance and scalability have become the prime requirements of every business.

The conventional or historically known good system architecture and technology stacks fail to meet today's business performance and scalability expectations. Addressing performance and scalability issues becomes challenging due to rapid technology evolution, increasingly diverse technology stacks, and complex deployment environments. Providing solutions to these needs under the constraints of existing technology choices, architecture, and investment calls for specialized performance and scalability engineering expertise and deep knowledge of various use case-specific technology stacks, middleware platforms, and compute alternatives.
