Beyond software, system architecture touches embedded systems in IoT devices for smart cities in Ahmedabad or Mumbai, and information systems for HRMS payroll—key in India's compliance-heavy job market. It evolves with trends like cloud-native designs on AWS or Azure, helping firms manage multimedia or event-driven flows. Ultimately, good architecture prevents downtime and boosts performance in our high-stakes digital economy.
Different Types of System Architecture
1. Monolithic Architecture
All of the components are deeply integrated into a single codebase and deployed simultaneously, making it an excellent choice for applications of a smaller scale. From the beginning of the 2000s, Amazon began using this for its retail website before expanding its operations. Although it makes initial development easier, it may act as a barrier to expansion as traffic increases.
For example, Instagram initially utilized a monolithic design to manage its platform for sharing photographs.
2. Client-server Architecture
In online applications, it is standard practice to have a central server manage requests from various client devices. Flipkart's e-commerce backend is built with this, which allows the company to separate user interfaces from data processing. While this configuration improves centralized control, it also risks failures at a single point.
Facebook, for example, takes advantage of technology in order to provide material to billions of people.
3. (SOA) stands for "service-oriented architecture."
Using established protocols, services communicate with one another, which encourages reusability across different systems. In order to integrate their historical core banking systems with contemporary application programming interfaces (APIs), Indian banks such as HDFC use service-oriented architecture (SOA). When applied in business settings that contain a variety of technology stacks, for example, eBay, for instance, employs SOA to handle its extensive e-commerce operations.
4. Microservices Architecture
Small, independent services are responsible for specific functions and grow independently using application programming interfaces (APIs). In response to the rapid expansion of its user base, Netflix made the transition to this streaming service. It is utilized by businesses such as Zomato in India for the purpose of order processing and tracking of deliveries.
For example, utilizing microservices, for instance, allows Netflix to provide tailored suggestions and streaming services.
5. (EDA) stands for event-driven architecture
Appropriate for real-time applications, components respond to events in an asynchronous manner. EDA is utilized by Uber for the purposes of ride matching and notification. As part of India's financial technology landscape, Paytm utilizes it to send transaction alerts.
For example, Uber, for instance, leverages EDA to instantaneously connect drivers and riders with one another.
6. Layered Architecture
The code is organized into layers such as display, business logic, and data access with this feature. For the purpose of achieving a clear distinction in payroll systems, TCS creates an enterprise HRMS using this. Compliance-heavy Indian companies benefit from increased maintainability as a result. For example, banking applications frequently make use of this.
7. The architecture known as peer-to-peer (P2P)
By performing the functions of both clients and servers, nodes decentralize control. For example, BitTorrent is largely responsible for its popularity; blockchain applications like Polygon use it for scalable transactions in India. Superb for ensuring resilience in the absence of central servers.
8. TPipe-and-filter Architectures
Architectures based on Pipes and Filters
Like a pipeline, data is processed through many phases. Image editing programs such as Photoshop make use of filters in a sequential fashion; Indian multimedia companies implement this technique for video streaming applications. Streamlines the process of transforming modular data. For example, compilers such as GCC make use of this for code translation.
9. Event-driven Messaging Architecture
Much like EDA, it makes use of message brokers in order to achieve loose coupling. Kafka is the platform that Spotify uses to provide playlist suggestions. During busy hours, Swiggy makes use of it to provide them with real-time order updates.
For example, Slack makes use of this for messages in real time.
10. Hybrid Architectures
Combines a variety of styles to produce individualized solutions. Indian startups like PhonePe combine microservices for payments and compliance with layered authentication. Social media combines microservices for feeds with tiered authentication. It provides unparalleled versatility.
For example, Amazon employs a combination of microservices, service-oriented architecture (SOA), and enterprise data architecture (EDA) to achieve scalability and efficiency.
