What is Chef?
Chef is an open source systems management and cloud infrastructure automation platform. Opscode created the Chef configuration management tool, and the company later changed its name to Chef. Chef transforms infrastructure into code to automate server deployment and management. It can also be termed as programmable infrastructure. Chef uses a pure-Ruby, domain-specific language (DSL) for writing system configurations. Below are the types of automation done by Chef, irrespective of the size of infrastructure:
- Infrastructure configuration
- Application deployment
- Configurations are managed across your network
Chef supports multiple platforms like AIX, RHEL/CentOS, FreeBSD, OS X, Solaris, Microsoft Windows and Ubuntu. Additional client platforms include Arch Linux, Debian and Fedora. Chef can be integrated with cloud-based platforms such as Internap, Amazon EC2, Google Cloud Platform, OpenStack, SoftLayer, Microsoft Azure and Rackspace to automatically provision and configure new machines.
What is the use of Chef?
Chef tool helps in speeding up the deployment process and software delivery. Being a DevOps tool it helps in streamlining the configuration task and managing the company’s server.
In other words, Chef manage the configuration or infrastructure by having a command code in its server.
For example – Our 100 systems needs new update and our users are not aware of latest versions. so Instead of them or system administrator, Chef will update the latest configuration into all systems automatically by having a code in its server like we have to install linux in all systems or install new apps or update apps with latest versions, so we will write a code with all details related to linux and update or about apps and push them in server. So now Chef will push a notification with all latest updates in all systems and you have to install. The work that would take 1 week to be finished, now its done in just 10 mins. This is the use of Chef tool.
