Preface,

It’s easy to get asked questions about concurrency in senior development interviews!

What to say when asked in a high-concurrency system architecture interview? See if you can answer these questions first, if not, quickly get the document I share to review!

  • Interview must ask second kill system demand solution
  • High concurrent system flow cutting
  • How to increase the sound of cache silver bullets infinitely
  • Nginx, LVS, Haproxyoxy
  • Service static, file governance and clustering
  • Nginx + Lua static resource compensation machine
  • Hotspot data degradation occurred during traffic distribution. Procedure

The Tomcat architecture analysis shared today teaches you a number of ways to improve concurrency

This book attempts to explain Apache Tomcat from the following aspects.

  • Basic design: mainly describes the core interface and concept of Tomcat, and describes the design concept of Tomcat.
  • Architecture and working principle: mainly describes the overall architecture of Tomcat and how to coordinate the modules closely to complete the related work of application server.
  • Features and usage of each module: Details the features of each module and how to use them to achieve a high-quality deployment architecture. Each aspect is integrated with relevant design concepts and architectural knowledge to make it easier for readers to view Tomcat from the perspective of middleware product architecture.

Since the focus of this book is on Tomcat, it is intended for practitioners who are familiar with the Java language and have a preliminary understanding of JavaWeb application development.

  • Java Web application developer
  • Application server and related middleware developers.
  • System operation and maintenance personnel
  • System architect.

This chapter mainly includes the following parts.

  • Overall architecture design of Tomcat and the concept of Tomcat components.
  • Tomcat startup and request processing.
  • Class loader for Tomcat.


The overall architecture

Tomcat Configuration Management

This chapter describes the configurations related to Tomcat in the following four aspects.

  1. JVM configuration: This section describes the JVM configuration items supported when Tomcat is started.
  2. Server configuration: this section describes how to configure $CATALINA_ BASE/conf.
  3. Web application configuration: describes Servlet container configuration and Web application customized deployment using context. XML. In addition, it introduced some very useful implementations of Web application filters that Tomcat provides by default.
  4. Management configuration: This section describes several Web application deployment and management modes supported by Tomcat, such as JMX and Ant.


Configuration management

In the Tomcat cluster

This chapter describes how to implement and configure clusters in Tomcat from a technical point of view.

  • Tomcat cluster architecture implementation scheme, and cluster communication framework Apache Tribes.
  • Tomcat Cluster configuration mode.
  • This section describes the Principles and configuration of Tomcat cluster deployment.
  • Cluster session synchronization.


The cluster

Tomcat performance tuning

  • Tomcat performance test and diagnosis: How to use tools and commands to test system performance, collect and analyze performance data.
  • Tomcat performance optimization: How to modify Tomcat configuration to improve server performance.
  • Application system performance optimization suggestions: Common application optimization solutions.


Performance tuning

This book systematically introduces the implementation scheme and usage of the Tomcat architecture from functional components, protocols, specifications, and detailed configurations, helping readers understand the architecture and working principles of the application server in detail. The main contents include:

  • Basic component architecture and working principle of Tomcat;
  • Design, implementation scheme, use mode and detailed configuration of Tomcat components;
  • Integration and performance optimization of Tomcat and Web server;
  • Extended Tomcat features such as embedded, Comet, and WebSocket are introduced.

The structure of Tomcat is very complex, but Tomcat is also very modular, find the most core module of Tomcat, you can learn quickly
