Software configuration management system open source

This is a comparison of notable free and open-source configuration management software , suitable for tasks like server configuration, orchestration and infrastructure as code typically performed by a system administrator. Depending on the management software these agents are usually deployed on the target system or on one or many central "controller" servers. Consider the impact if an agent-less tool loses connectivity to a node while making critical changes—leaving the node in an indeterminate state that compromises its production? It should also be listed as a supported platform on the project's web site. Not all tools have the same goal and the same feature set.

Software Configuration Management

Configuration management CM usually includes the updates and the versions that have been applied to software packages, as well as locations and network addresses of hardware devices. When a system needs a software or hardware upgrade, the user can access the CM program and database to see what is currently installed and then make a more informed decision about the upgradation needed.

Chef is one of the most popular SCM tools. It is basically a framework for infrastructure development. It offers libraries for building up an infrastructure, which can be deployed easily. It produces consistent, shareable and reusable components, which are known as recipes and are used to automate infrastructure. It comprises the Chef server, workstation, repository and the Chef client.

This is the central registry or brain of the entire process and acts as a hub. It carries information about the infrastructure and the cookbooks, which are used to instruct Chef on how each node must be configured. This is installed on the nodes; it contacts the Chef server, fetches cookbooks and executes them on the nodes.

The chef-client does the actual configuration. Chef provides various tools for designing the infrastructure. These are based on high-level programming languages such as Python and Ruby. Another SCM tool commonly used is Puppet. It was first introduced in as an open source configuration management tool. It is written in Ruby. This CM system allows defining the state of the IT infrastructure, and then automatically enforces the correct state. This information is stored in files known as Puppet manifests.

It discovers system information through a utility called Facter and compiles it into a system-specific catalogue containing resources and their dependencies, which are applied against the target systems. It ensures stability, reliability and consistency. It also aids close collaboration between developers and sys admins, enabling more efficient delivery of code.

Once Puppet is installed, every node physical server, device or virtual machine in the infrastructure will have a Puppet agent installed on it. There will also be a server known as Puppet Master. Implementation takes place during Puppet runs as per the steps shown in Figure 2. CFEngine is one of the most popular open source and fully distributed CM systems and provides automated configuration compute resources.

In addition, it provides cohesive management and monitoring of physical or virtual machines, tablets, embedded devices, cloud and mobile smartphones, and can be called an IT infrastructure automation framework. It is available in open source and commercial flavours. CFEngine is based on policies, which are used to deploy or patch up systems and are made up of promises. The latter are verified frequently to ensure full compliance with a desired state.

Bringing resources into the desired state for compliance with policies is known as convergence. All policies are made available to all resources with the use of the policy server. This server monitors compute resources across the IT network, based on policies. Client hosts need to ensure that they continuously fetch the latest and most up-to-date policies from the policy server and that they remain compliant based on the set of instructions available in the policy language.

Its responsibility is to execute and collect the output of cf-agent and send email notifications to the configured email addresses. It allows an authorised cf-runagent to start a cf-agent run. It provides a line of communication between the hosts.

It keeps the promises available in common and monitor bundles. It is the core of the CFEngine that manipulates resources based on policies. It commands cf-serverd to execute the cf-agent with its active policy and hence is responsible for the instant deployment of updated policy.

Juju is an open source configuration management and orchestration management tool. It enables applications to be deployed, integrated and scaled on various types of cloud platforms faster and more efficiently.

The main mechanism behind Juju is known as Charms that can be written in any programming language, whose execution is supported via the command line. They are a collection of YAML configuration files. Clients are available for Ubuntu, Windows and Mac operating systems. Juju supports the GUI as well as the command line. It has a more feature-rich command line in comparison to what can be achieved via the GUI, which supports the drag and drop feature to create a software stack.

Juju is limited to Ubuntu on the server side. Its Python version has a community patch to support CentOS. Rudder is an open source CM tool for managing IT infrastructures. It is written in Scala and works on top of the CFEngine. Rudder provides features such as host inventory, a Web interface, reusable policies, a policy editor, generation of per-host policies, API, change requests, etc.

CM applies rules on nodes. Rudder uses the asset management function to identify nodes for configuration management. Ansible is an open source platform for CM, orchestration and deployment of compute resources. It is built on the popular Python language.

It is possible to install Ansible by using the Git repository clone of a master server. Ansible is agentless. Its design goals are consistent, secure, minimal in nature and highly reliable, and it is easy to learn.

Its main features are:. Ansible has a collection of modules to manage resources on various cloud platforms such as Amazon EC2 and OpenStack. It also supports deployment of Big Data and analytics environments such as Hadoop, Riak and Aerospike. Salt is an open source multitasking CM and remote execution tool. It has a Python-based approach to represent infrastructure as a code philosophy. The remote execution engine is the heart of Salt. It creates a high speed and bi-directional communication network for a group of resources.

A Salt state is a fast and flexible CM system on top of the communication system provided by the remote execution engine. It is a CLI-based tool. You can use Git to install it. It provides an asynchronous file server to speed up file serving. Halite is a Web UI of Salt. Salt has a highly modular and extensible design to support diverse applications. The Salt system has different module types to manage specific actions such as remote execution and state management behaviour.

The dependencies required to run Salt are Python 2. Vagrant is an open source CM tool for building and managing easy-to-configure, reproducible and portable virtual development environments. It provides support for the libvirt plugin named vagrant-libvirt. Vagrant isolates dependencies and configuration within a single disposable, efficient and consistent environment.

It also provides consistent workflow for developing and testing infrastructure management scripts. It has a central configuration model that enables administrators to manage the configuration of compute resources efficiently. Bcfg2 uses the XML model for configuration specification. Thus, Bcfg2 uses XML schema validators and the custom schemas included in Bcfg2 to validate configuration specifications. It enables consistent, repeatable and verifiable descriptions of the target environment.

Bcfg2 has client-server architecture. It is used to manage configuration, deployment and orchestration of various distributed components that comprise a robust system. A prototype-based object-oriented language or domain-specific language is used for component configuration. It encapsulates systems in such a way that it is easy to manage components, to install them automatically and to de-provision.

If you're not sure why Software Configuration Management Tools are important, then here's why. Sometimes the frequent introduction of a large number of changes during the development process puts developers in an ambiguous and complicated situation, making the wrong choice between various modified versions of a software product, thereby delivering previous or different versions. This behavior will produce various wrong results, such as successfully passing the software test, finding fewer defects, etc. To avoid this situation, software configuration management is required.

Michael K. Software configuration management must be practiced for any software system from the moment any work on the software system begins to when support ceases for that system. In the E-World, which is an expression used to describe the environment in which web applications are developed and utilized, effective and time-efficient software configuration management must be practiced such that baselines are identified and changes are tracked to those baselines. However, this software configuration management effort must not impede development and must be clearly understood from a functional basis. The overwhelming time to market requirement for E-World development efforts can not tolerate any impediments to development time and responding to client needs.
