Past origins of JBOSS and Tomcat

This article introduces JBoss and Tomcat respectively, and compares JBoss with Tomcat to give readers a better understanding of JBoss and Tomcat. In recent years, JBoss and Tomcat have become two stars, and JBoss has become the most rapidly developing application server in the J2EE application server field. This article introduces JBoss and Tomcat in the market share and compares JBoss with Tomcat to help readers better understand JBoss and Tomcat. In recent years, JBoss and Tomcat have become two stars, and JBoss has become the most rapidly developing application server in the J2EE application server field. It has achieved great success in terms of market share and service satisfaction, and is no inferior to other non-open-source competitors, such as WebSphere, WebLogic, and Application Server. JBoss Web has many excellent performance, which is widely used. Based on the Tomcat kernel, the Blue Tomcat server is a free open-source Web application server with advanced technology, stable performance, and free of charge, therefore, it is favored by Java enthusiasts and recognized by some software developers. It consumes a small amount of system resources during running and has good scalability. It also supports common functions for development and application systems, such as load balancing and mail service. As a small lightweight application server, Tomcat is widely used in small and medium-sized systems and concurrent access to a large number of users. it has become a popular Web application server. JBoss Web adopts the best open-source Java Web engine in the industry. it downloads the largest number of users in the Java community and uses the most complete Tomcat kernel as its Servlet container engine, review and optimization. Pure Tomcat has limited performance and lacks performance in many places, such as active connection support, static content, large files, and HTTPS. In addition to performance problems, Tomcat is also a restricted integration platform that can only run Java applications. When using Tomcat, enterprises often need to deploy Apache Web Server at the same time for integration. This configuration is cumbersome and does not guarantee performance superiority. Based on Tomcat, JBoss localized it and integrated the built-in Tomcat method into JBoss. JBoss Web solves many Tomcat shortcomings by using a hybrid model of APR and Tomcat local technology. The hybrid technology model provides the best thread and event processing from the latest operating system technology. As a result, JBoss Web achieves scalability, and performance parameters match or even surpass the local Apache HTTP Server or IIS. For example, JBoss Web can provide database connection pool services. it not only supports Java technologies such as JSP, but also supports integration of other Web technologies, such as PHP and. NET. Standardization is the best way to reduce technical dependency risks and protect investment. JBoss Web is the first to support a full range of JEE Web standards, which fundamentally guarantees the "one-time development, running everywhere" features of applications, the application products can be easily migrated between JBoss Web and other Java Web servers. The JBoss Web server integrates multiple functions with excellent performance as a star product of Web application servers. Its key features include: full support for Java EE, high scalability, fast static content processing, clustering, OpenSSL, URL rewriting, and comprehensiveness. JBoss Web servers have native features and powerful scalability. they support a variety of server content processing technologies that are not based on Java and can run JSP, Servlet, and Microsoft at the same time. NET, PHP, and CGI provide a single, high-performance enterprise-level deployment platform. Compared with Tomcat, JBoss Web has superior performance in static resource access. JBoss Web supports two component modes: pure Java and Native I/O. With the support of Native components, dynamic operation will not be affected. However, access to static resources uses the 0 copy transfer provided by the operating system itself, reducing CPU consumption and shortening response time, the throughput is greatly improved. the hybrid connection mode supports simultaneous access of up to 10000 concurrent clients, which is equivalent to the Apache Web server. Deployed in a high-performance operating system, JBoss Web can be used to support pure Java and Native I/O modes, so that applications can be migrated across platforms at any time during development, it is deployed in a high-performance operating system-related Native environment. Because JBoss Web effectively solves the access performance problem of static resources, it can be directly used as a powerful LVS distribution object in the solution, combined with the RHEL load balancing system, theoretically infinite linear expansion of load balancing scenarios. OpenSSL is the fastest and most secure open-source transmission component in the industry. it enables efficient and secure bearer with operating system and hardware features. JBoss Web integrates OpenSSL to provide efficient secure transmission services, bringing the security mechanism to a higher level. Research shows that the SSL performance of JBoss Web is four times faster than that of Tomcat. The URL rewriting function can shorten the URL, hide the actual path, improve security, and make it easy for users to remember and type, and be indexed by search engines. Tomcat does not support URL rewriting. JBoss Web provides a flexible URL rewriting operation engine that supports unlimited number of rules and rule conditions. The URL can be rewritten to support the handling of legacy URL errors, or to cope with other problems arising from time to time on the server. JBoss Web can be run independently or seamlessly embedded into the JBoss Application Server, becoming part of the JBoss Middleware Platform. Not only will the performance of backend service calling be improved, but the following JBoss platform features can also be used to enhance Web application functions: ◆ support for various JGroups-based cluster solutions ◆ support for JTA and JTS transaction processing based on Arjuna technology ◆ support for optimized thread pools and connection pools ◆ support for basic management based on the JMX console and JBoss on advanced management and maintenance support ◆ support for aspect-oriented architecture based On JBoss AOP technology ◆ support for Hibernate service components professional teams support most open-source products in the industry in technical innovation, however, the lack of effective assurance in sustainability, product lifecycle planning, and quality assurance is criticized by software integrators and end users. RedHat's "professional open source technology" perfectly solves this problem. JBoss Web from the open-source community has become an excellent product in terms of performance, scalability, stability, and security under the tempering of the professional open-source development of RedHat. RedHat not only has a dedicated technical team to invest in JBoss Web development, but also has a dedicated QA team to ensure product quality. The complete integration test and compatibility test ensure the stability of JBoss Web and ensure its backward compatibility and good interoperability with other JBoss products. In terms of service system assurance, JBoss and Tomcat develop a software ecosystem model that uses expert-level support services provided by product experts as the powerful backing of open-source software. The company and a large JBoss authorized service partner network can provide comprehensive support services for the entire JEMS product suite, including JBoss Web. Compared with Tomcat, JBoss Web provides migration services and on-site expert services. in terms of migration services, experts guide applications to migrate from Tomcat to JBoss Web, saving time and effort. The unique service subscription mode guarantees the software life cycle, so that enterprises can rest assured
