Do you know what is Apache web server and how it works?

Well if you don’t know about it then no need to be worried anymore.

I bet you will get some fantastic knowledge in this article about your desired topics.

What is Apache Web Server?

It was developed by a group of 20 programmers.

Its first version was released in 1995. It runs on more than 65% web servers all over the world.

The most common reason for its popularity is that it is free and reliable.

Word press supports many other servers also, but this the most preferred one.

It consists of a library in which add-ons are present. It runs on many platforms.

These are the most common web server

1. HTTP server
2. Tomcat

What is a Web Server?

It uses hypertext transfer protocol to respond to the client’s request.

In this process, the client/server model is involved. It is necessary for a computer to have a server that intends to host a website.

Some of the most common ones are:

• IIS (Internet information server)
• NGINX
• Google server

While choosing a server, first see its workings. How well it works is quite essential.

Web servers support PHP and many other scripting languages.

Each of them has a load limit. It can handle a specific amount of load from the client at a time.

In the case of overload, there is a delay in the processing of the request.

Thus it becomes essential to manage network traffic.

What is the Client-Server Model?

In the client-server model, a server provides its services to one or multiple clients.

Some common examples include:

• Mail servers
• File servers

Explanation:

The client sends the server a request.

The server upon receiving the client’s request uses a protocol to build the connection with that client.

For example, while sending an email, first the email client sends a connection request to the mail server so that it may send the email.

Then the mail servers ask for authentication from that client.

This authentication may include the login details such as the username password. When the authentication succeeds, then the server sends an email to the recipient.

Use of Distributed Computing:

Now the servers have to provide their services to multiple clients with an increasing amount of traffic.

Many popular service providers currently use the distributed computing to make the work go smoothly.

What Does Apache Mean?

This name was chosen by an American Indian tribe because of their outstanding strategic skills of war and their endurance.

They came to South America many centuries ago.

They divided themselves into a group of people and fought for their independence.

They were composed of independent groups. Their politics, society, and culture were just awesome.

That’s why the group of programmers who developed this was also named as Apache group which is a Spanish word which meaning ‘enemy.’

HTTP Server:

One of the popular web servers. It provides many features to its users. Some of them are:

• It supports Windows, Linux, and many other operating systems. It supports many programming languages and is used to provide virtual hosting.
• Used by more than 55% websites.
• An Apache installation can host many websites.
• Comfortable with many graphical user interfaces.
• It works for both static and dynamic websites.
• Extensible, efficient and customization.
• It has the straightforward format of its configuration files.
• Reliable and stable.

What is HTTPd?

You would have also come across this word. Its full form is hypertext transfer protocol daemon. It is none other than the Apache HTTP server.

What is httpd.conf?

It is a configuration file in which different configuration properties are kept. The server looks for the features here. You can easily find it in settings.

What Does Apache HTTP Do?

This open source software has the majority of instances running on Linux distribution. The current ones run on Windows and Unix.

It has marvelous modules which increase the functionality. Some of its top features include:

• Server-side programming
• Authentication schemes
• SSL and TLS
• Proxy
• Filtering support

There are several compression methods on Apache too that serve for the size reduction of Web pages loaded over HTTP.

The code of the powerful software is freely available online and helps for a variety of complex needs with its beautiful addons.

Multiprocessing Modules:

Unlike other popular web server software, Apache doesn’t use a single architecture and provides brilliant Multiprocessing modules which make it run smoothly according to the requirements.

It is a reliable source for server-side work as it increases throughput, lowers the latency and handles a large number of requests at a time.

Tomcat Server:

Its connector component is the coyote. Tomcat’s JSP engine is JASPER.

A component in Tomcat performs the role of managing the large application. That component is known as a cluster. It has incredible availability features that look for the scheduling of system upgrades.

Tomcat is written in Java whereas HTTP server is in C. It provides services to Java technologies. If you are making any java application, then your first preference should be tomcat.

What is Apache Spark?

A data processing framework developed in 2009.

• Gives its user a comprehensive framework for data processing.
• Speeds up the writing of Java applications and helps to write Java application quickly.
• Quickly optimizes big data queries.
• A general purpose engine used for data processing.
• JVM language.
• Best for interactive analysis.
• Flexible in solving transformation problems.
• Provides I/O functionalities also.
• With Apache Spark, developers can quickly make applications.
• Very easy to use and runs everywhere.

It contains many libraries.

Some of them are:

• Spark SQL
• Spark Streaming
• Spark GraphX

Thus it’s a unified engine and is much easy to run on your machine. After its installation, you will have to connect to it through Spark shell. Its speed is faster than other.

Apache Camel:

It is a Java framework that provides services for its user to write Java applications efficiently and smoothly. It provides connectivity to many API’s.

It provides you with debugging tools also. It consists of Java libraries, is simple and is that’s why very easy to use. It also helps in transformation and monitoring.

By default, there is a set of components in this framework and is best for you if you intend to integrate applications with different protocols. It has excellent error handling. It has superior automatic testing services.

What is Apache Storm?

• For many years it was not more than an idea but now has become very popular because of its useful features.
• Its framework is also attractive.
• A computation system.
• Used for real-time processing.
• It integrates with your database technologies.
• Easy to grasp.
• Used for analyzing big data.
• Flexible and can be used with any programming language
• It also plays a vital role in telecommunication.
• It provides an impressive data processing platform to its users.
• Easy to use and operate.
• It helps in normalizing and analyzing a significant amount of data.

There are two types of nodes on storm cluster. These are:

1. Master node
2. Worker Node

Storm uses the unique library for inter-processing communication. The entry point in stream tool is called spout. It is used in connection with the data source.

PHP:

Its full form is hypertext preprocessor. It is a server-side scripting language which is primarily used on Linux.

It works as an alternative to ASP technology of Microsoft.

The PHP code is embedded in HTML code of a page.

It’s syntax matches with many other languages. Some of them include C and Perl.

Conclusion:

Now you know what Apache is and how it works.

Thus this invention is serving its users in the best possible way and in its every project it produces something for the ease of its user.

This technology has been serving people for years, and this will continue in making the life of developers easier.
