How can you change tomcat apache port number?
To change the port number of Apache Tomcat, locate the server.xml file in the conf directory of your Tomcat installation (e.g., TOMCAT_HOME/conf/server.xml). Open the file and find the <Connector> element that specifies the current port (usually 8080). Change the port attribute to your desired number, save the file, and then restart Tomcat for the changes to take effect.

Microsoft Internet Information Services (IIS)IIS is, at the time of writing, the second most popular web server on the web. It is however, gaining market share, and if the current trend continues, it won't be long before it overtakes Apache.IIS comes as an optional component of most Windows operating systems. You can install IIS by usingAdd/Remove Windows Components from Add or Remove Programs in the Control Panel.

1. Confirm That It's a Bandwidth Problem
As was stated above, not every report of a slow network connection is due to a bandwidth issue, but just about every bandwidth issue results in slow network performance for at least some users. So, if the initial report is slow network performance, we must first determine if it's related to bandwidth oversubscription or not. Fortunately, with the wide range of choices out there for network monitoring solutions, some based on flow-based technologies (NetFlow, sFlow, etc.) and some that are packet-based, correlating a problem report with overall network activity has become fairly straightforward. One simply needs to "rewind" the network activity to the period of time where slow network performance was reported, isolate the flow where the event was experienced, and then expand the view to include data collected at the router or switch level for the flow to see if the network link was oversubscribed. If so, a bandwidth issue of some sort is probably the cause, and a more detailed investigation is in order. Alternatively, most network monitoring solutions provide flexible alarms and notifications based on measurements like percentage of bandwidth utilization on a link. If a triggered alarm corresponds to the time of the report of poor performance, you've already answered the first question.
2. Determine If It's a One-Time Event
If your network monitoring solution indicates that a bandwidth threshold has been exceeded, the next thing to determine is the frequency of such an event. Is this the first time, or have similar incidents occurred in the recent past? If it is the first occurrence, and especially if it is still ongoing, you should dig in quickly to see who the top talker is. Though the event could be benign, like too much video being downloaded by too many users on the day of a popular event, it could also be an indication of something serious, like a distributed denial of service attack or a worm infection. Regardless of the cause, a spike in bandwidth that is unpredicted and outside of the norms for your network should be taken seriously and addressed immediately.
If similar bandwidth spikes have occurred before, or if you've already determined that certain spikes are part of the norm (eg. order processing spikes first thing in the morning when the operations department starts their day), make sure that the current spike conforms to one of these norms. The best way to determine this is to have current baseline measurements of typical network usage, since it is highly unlikely that network usage is constant throughout the day. Understanding what the load is at different times of the day, and what the peak historical usage has ever been, will help you tremendously in determining the severity of the next spike in bandwidth usage.
3. Remove Unnecessary Traffic
More often than not, bandwidth problems come from unnecessary traffic on the network, like real-time video streaming during the 7th game of the World Series. By pruning your WLAN traffic and removing or reducing superfluous demands through the use of bandwidth shaping technologies you can better control overall bandwidth usage and ensure that adequate bandwidth is always available for your mission critical applications.
These three steps should help you determine when and where bandwidth issues occur and how you can better manage your network to stop slow network performance caused by network bandwidth spikes.
What is the difference between the application server and internet information server?
An application server is a server program in a computer in a distributed network that provides the business logic for an application program. The application server is frequently viewed as part of a three-tier application, consisting of a graphical user interface (GUI) server, an application (business logic) server, and a database and transaction server. More descriptively, it can be viewed as dividing an application into:
A first-tier, front-end, Web browser-based graphical user interface, usually at a personal computer or workstation
A middle-tier business logic application or set of applications, possibly on a local area network or intranet server
A third-tier, back-end, database and transaction server, sometimes on a mainframe or large server
As Internet Information Server is a group of Internet servers (including a Web or Hypertext Transfer Protocol server and a File Transfer Protocol server) with additional capabilities for Microsoft's Windows NT and Windows 2000 Server operating systems. IIS is Microsoft's entry to compete in the Internet server market that is also addressed by Apache, Sun Microsystems, O'Reilly, and others. With IIS, Microsoft includes a set of programs for building and administering Web sites, a search engine, and support for writing Web-based applications that access databases. Microsoft points out that IIS is tightly integrated with the Windows NT and 2000 Servers in a number of ways, resulting in faster Web page serving.
