Open source web servers and application servers Most of the increasingly rich applications you use today feature a combination of static web content and dynamic application content, delivered via a combination of web server and application server technologies. The bottom line is that todayвЂ™s most popular web servers and application servers are hybrids of both.

To make matters more confusing, many web servers and some application servers are referred to, or refer to themselves, as web application servers. They also allow web applications to leverage services like reverse proxy, clustering, redundancy, and load balancing-services that improve performance and reliability and allow developers to focus less on infrastructure and more on coding. And an increasing number of application servers not only incorporate web server capabilities, but use HTTP as their primary protocol and support other protocols (e.g., CGI and CGI variants) for interfacing with web servers. Most web servers support plug-ins for scripting languages (e.g., ASP, JSP, PHP, Perl) that enable the web server to generate dynamic content based on server-side logic. In practice, however, the line between web servers and application servers has become fuzzier, particularly as the web browser has emerged as the application client of choice and as user expectations of web applications and web application performance have grown. The client for an application server can be the applicationвЂ™s own end-user UI, a web browser, or a mobile app, and the client-server interaction can occur via any number of communication protocols.

application server: What is the difference?Д«y strict definition, a web server is a common subset of an application server.ДЄ web server delivers static web content-e.g., HTML pages, files, images, video-primarily in response to hypertext transfer protocol (HTTP) requests from a web browser.ДЄn application server typically can deliver web content too, but its primary job is to enable interaction between end-user clients and server-side application code-the code representing what is often called business logic-to generate and deliver dynamic content, such as transaction results, decision support, or real-time analytics. When a domain is created, you are prompted for the administration user name and password.Learn how web servers and application servers are different, how theyвЂ™re the same, and how they combine to deliver most of the applications you use today. After installation, you can create additional domains as necessary. Each organization or administrator can administer the instances in a single domain without affecting the instances in other domains.ДЄt installation time, GlassFish Server creates a default domain that is named domain1. If the configuration is changed for one domain, the configurations of other domains are not affected.Дomains enable different organizations and administrators to share securely a single GlassFish Server installation. Each domain has its own configuration data, log files, and application deployment areas that are independent of other domains. A domain provides a preconfigured runtime for user applications. Each instance can belong to only one domain. Looking at the official documentation it doesn't sound like one application for one domain can gain access to another domains space.ДЄ domain is an administrative boundary that contains a group of GlassFish Server instances that are administered together.

To supply services to our clients we don't install different glassfish servers we give them different domains in the same glassfish server as I see it's the best strategy. Here I am talking about one linux server with one IP and one glassfish application server in that linux server. So either my vision is wrong or how can it be fixed? Here is the big difference - in apache it's the administrator who sets webserver folders for reading. Because it's the user sets alternate docroot folder not the admin. But now, every user can deploy his application and get another user's alternate docroot. In order for glassfish to get users' alternate docroots we open users' folders (/home/user1, /home/user2) for glassfish. So it's the place where he wants to have alternate docroot(s) to keep his data. Every user has access only to his home folder. and runs as 'glassfish' linux user.ДЄnd every user(client) wants to have an alternate docroot(s). Glassfish is installed in /usr/glassfish.

Every user has his user folder in /home (/home/user1, /home/user2). Let's suppose we give to different users(clients) different domains (one domain for one user) in our glassfish application server for their work.
