Apache: -
Apache is an open-source web server. It was developed by Apache software foundation group and released on 1995. Apache is an open-source web server. It is a process-based web server application that creates a new thread. It provides a database. Apache is the most widely used web server application in the world. Apache have an process driven architecture. It is widely used and historically dominant. Apache's modular architecture allows for dynamic loading of modules, which can be configured per server or per directory. Highly flexible and customizable, can handle dynamic content well. supports load balancing with modules like mod_proxy_balancer, but not as feature-rich or efficient as Nginx. Large and active community with extensive documentation and a wide range of third-party modules and plugins. Broad support available through community forums, mailing lists, and commercial support options. Apache servers’ power around 30% of websites worldwide. Apache server is popular for its module system that provides high performance and flexibility.
Administrators frequently opt for Apache due to its remarkable flexibility, robust performance, and widespread compatibility. Its dynamic module system allows for extensive customization, making it adaptable to various needs and environments. Furthermore, Apache's ability to directly serve scripting languages like PHP, without the need for extra software, adds to its convenience and efficiency. This versatility and ease of integration make Apache a go-to choice for many web server setups.
Mpm prefork: -
The mpm_prefork module in Apache works by creating processes, each with a single thread, to handle incoming requests. This means each process can only manage one connection at a time. It's very efficient as long as the number of requests doesn't exceed the number of available processes. However, once the requests surpass the number of processes, performance drops significantly, making it less suitable for high-traffic scenarios. Additionally, because each process consumes a lot of RAMS, scaling can be challenging. Despite these drawbacks, mpm_prefork is a good option when using components that don't work well with threads, such as PHP, which isn't always thread-safe. This makes it a reliable choice for working with the mod_php module in Apache.
Mpm worker: -
The mpm_worker module in Apache improves efficiency by spawning processes that can each manage multiple threads. Each thread is capable of handling a single connection, making this module more scalable compared to mpm_prefork. With more threads available than processes, new connections can quickly grab an available thread instead of waiting for a free process, enhancing performance and responsiveness. This threading approach significantly boosts scalability and resource management.
Mpm event: -
The mpm_event module in Apache works similarly to the mpm_worker module but has optimizations for handling keep-alive connections. In the worker module, a thread remains occupied by a connection for the entire duration it's kept alive, even if no request is being processed. The event module, however, uses dedicated threads specifically for managing keep-alive connections and transfers active requests to other threads. This approach prevents the system from being slowed down by idle keep-alive requests, ensuring faster and more efficient processing of active requests.
Apache can handle dynamic content by embedding the necessary language processors directly into its worker instances. This means it can execute dynamic content, like PHP, within the web server itself, eliminating the need for external components. These processors are enabled through dynamically loadable modules, making setup and customization straightforward.
This capability significantly contributed to the popularity of LAMP (Linux-Apache-MySQL-PHP) stacks, as Apache can natively execute PHP code, streamlining the process of serving dynamic web content.Virtual hosting in Apache allows you to run multiple websites on a single server. Each website, known as a virtual host, has its own domain name or IP address and is treated as if it has its own server. This is useful for shared hosting environments or when you want to host multiple websites on a single server. To set up virtual hosts in Apache, you typically create separate configuration files for each virtual host in the Apache configuration directory. Each virtual host configuration specifies the domain name or IP address it should respond to, as well as the document root where the website files are located. Apache then uses this information to route incoming requests to the appropriate virtual host.
You should choose Apache if you have:
Nginx: -
Nginx is a web server that was developed by Igor Sysoev and later Nginx Inc and released on 4 October 2004. Nginx server is event driven, asynchronous based architecture. it is rapidly growing by its high-traffic sites. It is especially popular for high-traffic sites. Nginx can also be used as a reverse proxy server which revises the request from the client and sends the request to the proxy server. It improves content and application quality and security. it is an open-source fast, lightweight and high-performance web server. Uses an asynchronous, non-blocking event-driven architecture that allows it to handle multiple connections within a single process. Excellent performance and resource efficiency, especially with static content and high concurrency. Handles more connections with less memory. Extremely efficient, designed to serve static content with high performance. Excellent load balancing capabilities with advanced features like health checks, session persistence, and dynamic reconfiguration. Basic security features included, but often relies on external modules or additional configuration for advanced security needs. Growing community with good documentation. Rapidly gaining popularity in the developer community.
Nginx has become more popular than Apache because of its lightweight design and ease of scaling on minimal hardware. It is highly efficient at serving static content quickly and includes a robust module system. Additionally, it can proxy dynamic requests to other software seamlessly. Administrators often choose Nginx for its efficient use of resources, responsiveness under heavy loads, and its simple configuration syntax. Nginx was developed with a keen understanding of the concurrency challenges faced by large-scale sites. It uses an asynchronous, non-blocking, event-driven architecture to manage connections efficiently. Nginx spawn’s worker processes, each capable of handling thousands of connections by using a fast-looping mechanism to check for and process events. In this system, each connection is managed within an event loop, where events are processed asynchronously. This means a worker process only deals with a connection when an event occurs, allowing for non-blocking operations. When a connection is closed, it is simply removed from the loop. This approach enables Nginx to scale effectively with minimal resources. Unlike other servers that spawn new processes or threads for each connection, Nginx maintains consistent memory and CPU usage, even under heavy load. This makes it highly efficient and reliable for high-traffic websites. Nginx cannot process dynamic content on its own. Instead, it forwards requests for dynamic content, like PHP, to an external library for execution and waits for the output to return, which it then sends to the client. These requests are exchanged using protocols that Nginx supports, such as HTTP, Fast CGI, SCGI, uWSGI, or Memcached. In most cases, PHP-FPM, a Fast CGI implementation, is used as a simple solution. Unlike some servers, Nginx isn't tightly integrated with any specific language, making it versatile for various applications.
Nginx was designed to function as both a web server and a proxy server, focusing on URIs rather than filesystem paths. This is reflected in its configuration files, where you configure how URIs are handled instead of setting up filesystem directories.In Nginx, the main configuration blocks are the server and location blocks. The server block specifies the host being requested, while the location blocks define how different parts of the URI should be processed. This means that Nginx interprets requests based on their URIs first, rather than their physical location on the server's filesystem. In Nginx, virtual hosting is achieved using server blocks within the main configuration file. Each server block represents a separate virtual host, allowing you to run multiple websites on a single server. Here's how it works:
You should choose NGINX if you have:
Sr No. | Apache | Nginx |
| 1. | Uses a process-driven model, with one thread per request. | Uses an event-driven model, handling multiple requests within one thread. |
