Popular API Architecture Styles

1. gRPC: A high-performance, language-agnostic remote procedure call (RPC) framework for efficient communication between distributed systems, often used in microservices architectures.

2. SOAP: A protocol for exchanging structured information in the implementation of web services, known for its strict standards and XML-based message format.

3. GraphQL: A query language and runtime for APIs that allows clients to request only the data they need, reducing over-fetching and under-fetching of data.

4. Webhook: A mechanism for real-time communication where an application sends HTTP POST requests to a predefined URL to notify and trigger actions in another system.

5. REST: Representational State Transfer, an architectural style for designing networked applications, using standard HTTP methods (GET, POST, PUT, DELETE) to manipulate resources.

6. WebSocket

Domain-Driven Design (DDD)

DDD was introduced in Eric Evans’ classic book “Domain-Driven Design: Tackling Complexity in the Heart of Software”. It explained a methodology to model a complex business. There is a lot of content in this book, so I'll summarize the basics.

The composition of domain objects:
- Entity: a domain object that has ID and life cycle.
- Value Object: a domain object without ID. It is used to describe the property of Entity.
- Aggregate: a collection of Entities that are bounded together by Aggregate Root (which is also an entity). It is the unit of storage.

S - Single Responsibility Principle 👩‍💻👨‍💻
Each class/module should have only one reason to change. Keep your code focused on doing just one thing - it leads to easier maintenance and enhances readability. 🧐

O - Open/Closed Principle 🌐🔒
Software entities should be open for extension but closed for modification. Build systems that allow you to add new features without altering existing code. 🛠

L - Liskov Substitution Principle 🧩✅
Derived classes should be substitutable for their base classes without affecting the correctness of the program. Ensuring compatibility and consistency in your object-oriented design. 🧬

I - Interface Segregation Principle 📦🕹
Clients should not be forced to implement interfaces they don't use.

D - Dependency Inversion Principle 🔄🔗
High-level modules should not depend on low-level ones; both should depend on abstractions. Decouple components and promote better scalability and testability.

Top 8 Cache Eviction Strategies

🔹 LRU (Least Recently Used)
LRU eviction strategy removes the least recently accessed items first. This approach is based on the principle that items accessed recently are more likely to be accessed again in the near future.

🔹 MRU (Most Recently Used)
Contrary to LRU, the MRU algorithm removes the most recently used items first. This strategy can be useful in scenarios where the most recently accessed items are less likely to be accessed again soon.
