devops: What IS?

DevOps is the practice of operations and development engineers participating together in the entire service lifecycle, from design through the development process to production support.

DevOps is also characterized by operations staff making use many of the same techniques as developers for their systems work.

ToolS

Dev

JIRA

Jira is a proprietary issue tracking product, developed by Atlassian. It provides bug tracking, issue tracking, and project management functions.

Alternative: TFS, YouTrack

GitHUB

GitHub is a Web-based Git version control repository hosting service. It is mostly used for computer code. It offers all of the distributed version control and source code management functionality of Git as well as adding its own features

Alternative: GitLab, Bitbucket, Beanstalk

SLACK

Slack is a cloud-based set of team collaboration tools and services which support Bot and have Integration with other tools

Alternative: Flock, Hipchat

ChatOps integrates development and deployment tools into chat platforms to ensure that key DevOps functions can be run from within chat conversations.

For example:Slack lets you send commands directly to and receive data directly from GitHub,

Chatops

Jenkins: what is?

Jenkins is an open source automation tool  with plugins built for Continuous Integration purpose. Jenkins is used to build and test your software projects continuously making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build.

Alternative: Circle CI, Travis CI

Docker: WHAT?

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications.

You Have Package Contains:

               OS Configuration

               Service Configuration

               Hardening Configuration

Ansible

Infrastructure as A Code (IAC)

Process of managing and provisioning computer data centers through machine-readable definition files (scripts), rather than physical hardware configuration or interactive configuration tools

- Similar to programming scripts

- Automate important IT processes.

- Automate a series of static steps that must be repeated numerous times across multiple servers.

Ansible

You can use Ansible to automate three types of tasks:

• Provisioning: Set up the various servers you need in your infrastructure.
• Configuration management: Change the configuration of an application, OS, or device; start and stop services; install or update applications; implement a security policy; or perform a wide variety of other configuration tasks.
• Application deployment: Make DevOps easier by automating the deployment of internally developed applications to your production systems.

Ansible: Example

---
- hosts: webservers
  vars:
    http_port: 80
    max_clients: 200
  remote_user: root
  tasks:
  - name: ensure apache is at the latest version
    yum: name=httpd state=latest
  - name: write the apache config file
    template: src=/srv/httpd.j2 dest=/etc/httpd.conf
    notify:
    - restart apache
  - name: ensure apache is running (and enable it at boot)
    service: name=httpd state=started enabled=yes
  handlers:
    - name: restart apache
      service: name=httpd state=restarted

Apache HTTP

Monitoring

Zabbix

Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers. Zabbix uses a flexible notification mechanism that allows users to configure e-mail based alerts for virtually any event. This allows a fast reaction to server problems. Zabbix offers excellent reporting and data visualisation features based on the stored data.

LogStash and Kibana

Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana 3 is a web interface that can be used to search and view the logs thatLogstash has indexed.
