Apache is open source software owned by the Apache Software Foundation (ASF) that guarantees the performance, stability and security of a web server. It has become very popular with programmers due to its modularity and constant updating by the community, which actively contributes to the high capacity of this tool. Ivan de Souza Feb 14, 20 | 7 min read apache server how it works Initially, you may be curious about the name of the Apache server , which refers to the tribe of Native Americans known for their great resistance in combat and the superiority of their war strategies. Some say that the reference is related to a specific and more important characteristic of the software: being open source , it is free of private interests and immune to vulnerabilities and threats , since it is constantly updated. Furthermore, it can be considered a patchy server, that is, a server “patched” by numerous patches.
The software remains extremely stable and capable of handling various requests on the web. But what really intrigues is the success of this software, used by 43% of all websites we know of. Giants such as Netflix, Airbnb, eBay, Cisco, BBC, IBM, Nike, Microsoft, among many, are just some examples that take advantage of the functionalities of this server that responds to requests for access to content from multiple users simultaneously. Now, do you want to know more about it? Keep reading! Since in this article, you can learn:What is Apache? How does Apache work? What are the disadvantages of Apache advantages over other web servers? Why use Apache? Good reading! What is Apache? Apache Software Foundation (ASF) or Apache Foundation is a non-profit organization that, according to the Apache.org website :“(…) Develops, guides and incubates hundreds of enterprise-level projects, available for free, that serve as the backbone of some of the most visible and widely used applications in computing today. Through the ASF merit-based process known as “The Apache Way,” more than 730 individual volunteer members and more than 7,000 code contributors on six continents are successfully collaborating on innovations in Artificial Intelligence and Deep Learning, Big Data, Data Management. Build Data, Cloud Computing, Content Management, DevOps, IoT and Edge Computing , Mobile, Servers and Web Frameworks , among other categories ”. Apache was created in 1995 and is the core technology responsible for the initial growth of the Internet .
In short, it is open source software, that is, it receives contributions from developers around the world , since the original source code is available for free for your viewing and collaboration. For this reason, it has become very popular among programmers , who configure their own modules, apply specific functionalities and improve their resources to work on various projects in the technology area. According to the site itself, they are: more than 200 million lines of code in administration; 1,058,321,099 lines of code confirmed; 3,022,836 code confirmations; 730 individual ASF members; 7,000 Apache code checkers; active community of volunteers; more than 350 projects and initiatives; more than 300 top-level projects; 52 projects in the Apache incubator. Together with other components (LAMP —Linux, Apache, MySQL and PHP—), it acts to provide content on the web . Its integration goes as follows: While Linux is the operating system that performs the operations, Apache is the software that processes requests over HTTP. On the other hand, MySQL is a database, which stores all the processed information in an intelligible format and PHP is the programming language that creates dynamic content. Most applications run from LAMP components, especially since it is easy to create and free of charge.
Apache communicates on the network using the TCP / IP or HTTP / S (Hyper Text Transfer Protocol Secure) protocol, which defines how messages are formatted and transmitted from requests and commands at gate 443. How does Apache work? The process of running Apache is simple and basically comprises the following steps:obtaining the IP address of the domain from the cache search or through the DNS (Domain Name System) server —all sites receive an IP address when they are first created on the web server—;request for the full URL by the browser; response from the server, which sends the requested pages or an appropriate message to the user, in cases where the pages do not exist ( 404 error message ) or in the occurrence of another error (401 error, for example, which occurs when access is denied due to lack of credentials). Advantages and disadvantages of Apache over other web serversNGINX vs Apache NGINX software was created to solve the problem of processing failure when more than 10,000 user connections occurred simultaneously (c10k) and has also gained popularity. Basically the biggest advantage of NGINX over Apache is that it handles one request at a time from a single process and therefore performs better when faced with a higher volume of requests. In contrast, Apache is easier to configure and more user-friendly. Tomcat vs Apache Tomcat was created by the ASF itself and therefore its official name is Apache Tomcat. Like Apache, it is an HTTP server , but it serves Java- like requests rather than static websites.
Apache’s superiority over Tomcat is that it understands other programming languages, being more flexible. Also, Tomcat has a more difficult setup, especially if the demand is to run a website or landing page on WordPress , regardless of whether it was created alone or through Rock Stage . Why use Apache? Price Apache is open source software, which means that it is available for download or modification by anyone, free of charge . Its source code can be adapted to meet the individual needs of each business. This allows Apache to have a significant advantage over other servers: there is no need to sacrifice resources, no software license fees or support fees are charged to maintain continuity for programs that use it as a web server . Means Apache is a powerful tool, with features that compare to its high-value competitors . The software includes: administrative control panel; I send personalized error messages; authentication schemes; virtual host module that allows multiple sites to run simultaneously; domain name service; SMTP (Simple Mail Transfer Protocol); FTP (File Transfer Protocol). In addition, there are other third-party added features that can be installed, so that it is possible to customize the web server. This is because the Apache developer community constantly updates the code, without restricting access to resources and security patches for other users.
