-“Serverless” is a cloud computing execution model that allows developers to deploy and run applications without managing servers. In a serverless architecture, the cloud provider is responsible for managing and maintaining all the underlying infrastructure, including servers, virtual machines, networks, and storage. Developers only need to focus on writing code, without worrying about server configuration, scaling, and capacity planning. The core features of serverless architecture：

Introduction

The Snowflake Algorithm is a distributed ID generation algorithm developed by Twitter. It is designed for high-concurrency environments to generate globally unique IDs with sequential order, uniqueness, and high performance.

JDK Dynamic Proxy

The JDK Dynamic Proxy is a built-in feature of the Java platform that allows you to create a proxy object that delegates method calls to a target object. The target object is usually an interface or a class that implements the methods you want to expose to the proxy.

BitMap

A bitmap is a data structure that stores a collection of bits, each representing a binary digit (0 or 1). It is used to store a large collection of binary values efficiently. In this case, we can use a bitmap to store a large collection of numbers and check if a given number exists in the collection.

BIO: Blocking I/O NIO: Non-Blocking I/O AIO: Asynchronous I/O

Type	Advantages	Disadvantages
BIO	- Simple to use - Suitable for small-scale applications	- Blocking, low efficiency - Wastes thread resources
NIO	- Non-blocking, high efficiency - Suitable for high concurrency scenarios	- Higher programming complexity - Requires more system resources
AIO	- Fully asynchronous, best performance - Suitable for large-scale applications	- Complex implementation - May lead to resource management issues

1. Storage Location

• Local Storage: Stored on the client (browser) and tied to a specific domain. Each site has its own Local Storage, and data is not automatically sent to the server.
• Cookies: Also stored on the client, but they are sent to the server with every request.
• Sessions: Stored on the server. The client stores only the Session ID, which is used to retrieve data on the server.

Pessimistic Locking and Optimistic Locking are two common concurrency control strategies used to handle data consistency issues when multiple threads or processes access shared resources. The main difference between them lies in their approach to handling resource contention.
