Differences between WebLogic, WebSphere, JBOSS, and Tomcat

1. Product Introduction:

WebLogic is an application Server produced by American BEA Company, which is a middleware based on J2EE architecture. BEA WebLogic is a Java application server for developing, integrating, deploying and managing large distributed Web applications, network applications and database applications. Bring the dynamic capabilities of Java and the security of Java Enterprise standards to the development, integration, deployment, and management of large-scale web applications.

WebSphere is IBM’s integrated software platform. It encompasses the entire middleware infrastructure, such as servers, services, and tools, needed to write, run, and monitor round-the-clock, industry-strong, on-demand Web applications and cross-platform, cross-product solutions. WebSphere provides reliable, flexible, and robust integration software.

JBoss is a container and server that manages EJBs and supports the EJB 1.1, EJB 2.0, and EJB3.0 specifications. The JBoss core service, however, does not include a WEB container that supports servlets/JSPS and is typically used with Tomcat or Jetty bindings. In 2006,Jboss was acquired by Redhat.

Tomcat is a core project of the Apache Software Foundation’s Jakarta project, developed by Apache, Sun, and several other companies and individuals. With Sun’s involvement and support, the latest Servlet and JSP specifications are always present in Tomcat, and Tomcat 5 supports the latest Servlet 2.4 and JSP 2.0 specifications. Because of its advanced technology, stable performance, and free, Tomcat is deeply loved by Java enthusiasts and recognized by some software developers, and has become a popular Web application server.

2: Different prices:

JBoss and Tomcat are free. WebLogic and WebSphere charge a fee and are expensive.

3: Different open source:

JBoss and Tomcat are fully open source, while the other two are not.

4. Technical support:

Tomcat does not support EJBs. JBoss implements the EJB container and integrates Tomcat. Both WebLogic and WebSphere provide comprehensive support for a wide range of industry standards, including EJB, JSB, JMS, JDBC, XML, and WML, making it easier to implement Web applications and protect investments, as well as making it easier to develop standards-based solutions.

5: Different expansibility:

Both WebLogic and WebSphere are known for their highly extensible architecture, including sharing of client connections, resource pooling, and clustering of dynamic Web pages and EJB components.

6: Differences in application scope:

Tomcat is a small lightweight application server that is widely used in small and medium sized systems and where there are not many concurrent users. It is the first choice for developing and debugging JSP programs. WebLogic and WebSphere are business software, full of features and powerful, mainly used for large projects in large enterprises. JBOSS is primarily used by small and medium-sized companies with EJB services.

7: The difference between business services and technical support:

Since JBoss and Tomcat are both open source and free, there are no commercial services or technical support for them, while WebLogic and WebSphere have technical documentation and related services in place. If your server goes down one day, as long as you can afford it, Their technical engineers will be right in front of you.

8: Security issues

Since both JBoss and Tomcat are open source, they have relatively low security, and if the application server itself has a bug, you can’t claim Apache. WebLogic and WebSphere have proven their fault tolerance, system administration, and security capabilities in thousands of mission-critical environments around the world.

9: Close integration with database:

If the hardware cost is much higher than the software cost, use Weblogic/Websphere instead. It’s so simple why telecom/banking/mobile companies use Oracle or DB2 databases instead of mysql. Tomcat alone cannot support that amount of concurrency. If you have the money, opt for commercial products.

The differences between these Web servers are outlined in nine ways.

It is worth mentioning that Tomcat, WebLogic, Websphere and Jboss are also called middleware. In simple terms, middleware is the bridge between operating system and application program. Without middleware, your written applications (mostly Web Application and J2EE) cannot run.

How great is the middleware technology that won the second prize of national Science and Technology Progress?

The first middleware we know of is something called Tuxedo, which is essentially a transactional middleware. In 1998, IDC had a definition of middleware, and divided it into six categories according to its use. Today only message-oriented middleware and transactional middleware remain, the rest have been gradually integrated into other products, wrapped in, no separate product form in the market.

Around 2000, the Internet took off, and with it came a new thing, application servers. In fact, transaction middleware also belongs to application server, in order to distinguish, people’s traditional transaction middleware is called distributed transaction middleware, because it is mainly applied in distributed environment, and the new application server is called J2EE middleware. So far, this is a very popular product in the market.

After the concept of EAI came out, some new software products were introduced in the market, such as workflow, Portal, etc., but I did not know how to classify them, so it could not be classified as application, and could not be classified as operating system, so it was classified as middleware, so the concept of middleware was further expanded. At present, the market for middleware, each argument is different, objectively also led to the complexity of understanding.

Today, there are many new concepts on the market, such as three-tier architecture, components, Web services, and SOA(Service-oriented Architecture) is the most popular one. In fact, they are not a product, but a technical implementation method, a methodology for developing software. We know that the earliest software development method is programming, writing code, its drawback is that can’t reuse, therefore puts forward the component-based software development method, through the programming of some commonly used function encapsulation, and standardize the uniform interface, for other programs call, we develop a new software, for example, may use component 1, 2, 3 components of components, so, We can simply assemble it locally and get the application we want. After the Internet gained popularity emphasis on software development method based on components and new development, the core idea is the software does not need to include artifacts, need is the component of operation results, write a communication transmission software, for example, can the Internet looking for components, and puts forward the service request and get results back, and don’t need to download the component and package, This is what is now known as SOA. For SOA to become a reality, it is necessary to regulate the component interfaces, as well as the service results delivered by the components, so that new software development ideas can be implemented. But SOA is not a product, it is a way of thinking, and the only way to do that is middleware.

So what exactly is middleware and what isn’t? Intersoftware should have two key characteristics: first, it should serve the upper application layer, which is a basic condition; In addition, it must be connected to the level of the operating system, and keep running state, with such two characteristics can be called middleware.
