Microservices allow each service to be scaled independently for improved performance, making the system more flexible and adaptable to varying loads.
A service mesh provides a dedicated infrastructure layer for handling service-to-service communication, ensuring reliability and security.
Load balancing aims to distribute workloads evenly, which enhances performance and prevents any single server from becoming a bottleneck.
Microservices architecture allows for more flexible, independent scaling and development, which facilitates easier evolution of systems over time.
A reverse proxy forwards requests to backend services, which helps in routing, load balancing, and providing an additional layer of security.
Sharding involves distributing data across multiple machines to improve load balancing and increase the availability and reliability of the database.
Stateless applications treat each request independently without relying on stored session data, making them easier to scale and manage.
Service-oriented architecture (SOA) is a design pattern that structures applications as collections of loosely coupled services to enhance flexibility and reusability.
Microservice architectures typically introduce more complexity due to the need for efficient communication and data management among different services.
Distributed databases are often preferred for scalable architectures because they can handle large volumes of data and distribute processing across multiple servers.
