Apache HTTP Server, often referred to simply as “Apache,” is free, open-source, cross-platform web server software. It is released under the permissive Apache License 2.0 and developed and maintained by a collaborative community of developers under the guidance of the Apache Software Foundation.
This project is jointly managed by a group of volunteers worldwide, who leverage the Internet and the Web to seamlessly communicate, plan, and develop the server and its related documentation.
Apache HTTP Server is a robust, cross-platform solution offering smooth operation across many operating systems. It supports Unix-like systems, including macOS, Linux, and FreeBSD, as well as Windows. Approximately 92% of Apache HTTP Server instances run on Linux distributions.
This project is a collaborative software development effort to create a robust, commercial-grade, feature-rich, and freely available source code implementation of an HTTP web server.
This project is part of the Apache Software Foundation, a community-driven organization that fosters open-source software development. Hundreds of users and developers have contributed to this project, sharing their ideas, code, and documentation. The Apache Software Foundation aims to provide robust and commercially viable implementations of various software types. This foundation serves as a vital platform, empowering both individuals and institutions to build highly reliable systems for experimental research and mission-critical applications.

Minimum System Requirements
Management Server, Database, and Storage System Requirements
Machines running the Management Server and MySQL database must match the needed requirements. These machines may handle primary and secondary storage through local disk or NFS. The Management Server may be placed on an Instance.
- Operating system:
- Preferred: EL8+ or Ubuntu 22.04 or higher
- 64-bit x86 CPU (more cores result in better performance)
- 4 GB of memory
- 250 GB of local disk (more results in better capability; 500 GB recommended)
- At least 1 NIC
- Statistically allocated IP address
- Fully qualified domain name as returned by the hostname command
Host/Hypervisor System Requirements
Host is where cloud services appear as guest virtual machines. Each host is one machine that meets the following requirements:
- Must support HVM (Intel-VT or AMD-V enabled).
- 64-bit x86 CPU (more cores result in better performance)
- Hardware virtualization support is required
- 4 GB of memory
- 36 GB of local disk
- At least 1 NIC
- Latest hotfixes applied to hypervisor software
- When you deploy CloudStack, the hypervisor host must not have any VMs already running.
- All hosts within a cluster must be homogeneous. The CPUs must be of the same type, count, and feature flags.
