Introduction to DevOps

DevOps is a relatively new term in the technology industry, and it is often used to describe a set of practices and tools that enable software development teams to work more collaboratively and efficiently. In simple terms, DevOps is the combination of software development and IT operations, with the goal of streamlining the entire software development life cycle.

DevOps is an ever-evolving field and requires professionals to have a wide range of skills and knowledge. Professionals must be well-versed in both development and operations and must be able to apply their technical expertise to process improvement and automation.

Common DevOps Roles and Responsibilities

DevOps professionals may have a variety of roles and responsibilities, depending on the organization they work for. Generally, they are responsible for developing, deploying, and managing software applications, as well as automating processes, monitoring systems, and responding to incidents and issues.

Here are some of the most common DevOps roles and responsibilities:

• Developing and maintaining continuous integration and continuous delivery pipelines
• Automating software deployments
• Configuring and managing cloud infrastructure
• Implementing and managing security protocols
• Developing and managing test environments
• Analyzing system performance and identifying areas for improvement
• Developing and maintaining system and application monitoring
• Responding to incidents and outages

• Accessibility. This software is open source. This means that it can be used or modified by anyone for free. Developers around the world create configurations and web server modules for their specific needs. For the same reason, Apache regularly receives useful additions that extend its basic functionality.
• Configuration flexibility. Apache uses several configuration files to manage the web server. This allows the software to be customized for specific tasks.
• Functionality. Apache has a dynamic modular structure. You can quickly connect additional functionality in the form of downloadable modules, even without recourse to external sources. This allows you to solve a whole set of critical tasks in the area of security, caching, URL editing, load balancing. Thanks to the hybrid MPM modules, Apache can handle static and dynamic content equally well. It’s possible to quickly disable unnecessary modules and speed up the web server.
• Cross-platform. Apache works on Windows as well as all Unix-like systems. Administration of the web server has no major differences in different operating systems. Individual only the installation process and the location of the directory with the program files.
• Compatibility. Apache works on the basis of scripting or web-oriented languages (PHP, Python, Tcl, Ruby, Perl, ASP), which makes it compatible with the widest range of databases and server software. Many web applications and tools come ready to run from under Apache as a PHP module. The web server supports FastCGI and CGI technologies, allowing you to use software products in the object-oriented languages Java, sh, C, C++.
• Scalability. Suitable for web resources of any size. Apache works well for a single-page site (landing page) as well as for a multi-page site with tens of thousands of daily visitors.
• User support. Apache has been a leader in popularity among web servers since 1996. During this time it has developed an extensive base of documentation, both official and from third party developers. Ready-made, detailed manuals can be found for almost any scenario.

Cons

• Performance. Apache’s request processing speed is somewhat slower compared to its competitors. The flexibility of the web server hurts performance in some cases. For example, Apache has to read several configuration files on the server each time, consuming system resources and time. But this and many other factors can be fixed by disabling unnecessary options. However, in this case Apache functionality will not differ much from other web-servers.
• A complex configuration increases vulnerability. The ability to plug modules into Apache is not always an advantage. The more modules there are, the more complex the configuration becomes. Accordingly, there are more chances of allowing critical gaps in the security loop.
• The syntax of the config files. A variety of variables are used in the program’s parameter files, so setting up and managing a web server can seem complicated for newcomers. You can simplify the administration of Apache by using the free Apache GUI tool.
• Superfluous functionality. Even without additional modules Apache provides users with a lot of opportunities. True, most use only a small part of the basic functionality of the application. Therefore, it is often necessary to spend time after installation to disable “unnecessary” modules.

Apache consists of a kernel and a dynamic module system. The system parameters are changed through configuration files.

Kernel

The Apache kernel is developed by the Apache Software Foundation in C. The main functions are handling configuration files, the HTTP/HTTPS protocol and module loading. The kernel may run without modules, but will have limited functionality.

Modular system

A module is a separate file, the connection of which extends the original functionality of the kernel. They can be included in the software during the initial installation or loaded later by changing the configuration file.

Most of them are responsible for some aspect of client request processing – support for different programming languages, security, caching, authentication, etc. Thus, a large task is broken up into several phases, each of which is handled by a separate, highly specialized module.

For Apache, there are more than 500 modules. Many popular web applications are also available as modules for Apache. Examples include ISPmanager and VDSmanager.

Apache Configuration

The Apache configuration system is based on text files with prescribed settings. It is divided into three levels, each of which has its own configuration file:

The server configuration level (httpd.conf file) is the main configuration file. It applies to the entire web server mechanism.

Directory level (.htaccess file) – additional configuration file. Its directives cover only the directory where the file is located, as well as subdirectories.
Virtual host level (httpd.conf> or extra/httpd-vhosts.conf file).
Normally, Apache configuration files are in the “conf” folder, and additional configuration files in the subfolder “extra”. You can make changes either by editing the file itself or by using the command line.

Virtual hosts

A web host is a server component responsible for serving a single object placed on it (a website, a virtual server). The Apache virtual host system allows you to run several projects from the same IP address at the same time.

In Apache you can set module and kernel settings, and set limits on server resource consumption (traffic, RAM, CPU) for each virtual host individually. This is the technological basis of the entire web hosting mechanism.
