Introduction into Git

• Git is currently the most popular implementation
  of a distributed version control system.
• Git originates from the Linux kernel development
  and was founded in 2005 by Linus Torvalds.
  Nowadays it is used by many popular open source
  projects, e.g., the Android or the Eclipse
  developer teams, as well as many commercial
  organizations.
• The core of Git was originally written in the
  programming language C, but Git has also been
  re-implemented in other languages, e.g., Java,
  Ruby and Python.

Introduction into Jenkins

• Continuous Integration, also know as CI, is a
  cornerstone of modern software development. In
  fact it is a real game changerwhen Continuous
  Integration is introduced into an organization,
  it radically alters the way teams think about the
  whole development process.
• It has the potential to enable and trigger a
  series of incremental process improvements, going
  from a simple scheduled automated build right
  through to continuous delivery into production.
• A good CI infrastructure can streamline the
  development process right through to deployment,
  help detect and fix bugs faster, provide a useful
  project dashboard for both developers and
  non-developers, and ultimately, help teams
  deliver more real business value to the end user.
  Every professional development team, no matter
  how small, should be practicing CI.

6
Features

• Free Open-Source Tool
• Integrate all your DevOps stages with the help of
  around 1000 plugins
• Script your pipeline having one or more build
  jobs into a single workflow
• Easily start your Jenkins with its WAR file
• Provides multiple ways of communication
  web-based GUI, CLI and REST Api

7
Introduction into Docker

• Docker is a tool that enables you to create,
  deploy, and manage lightweight, stand-alone
  packages that contain everything needed to run an
  application (code, libraries, runtime, system
  settings, and dependencies). These packages are
  called containers.
• Each container is deployed with its own CPU,
  memory, block I/O, and network resources, all
  without having to depend upon an individual
  kernel and operating system. While it may be
  easiest to compare Docker and virtual machines,
  they differ in the way they share or dedicate
  resources.
• Containers help expand your Linodes
  functionality in a number of ways. For example,
  you can deploy multiple instances of nginx with
  multiple stagings (such as development and
  production). Unlike deploying multiple virtual
  machines, the deployed containers will not tax
  your Linodes resources.

8
Features

• Use Docker container with any language
• Ship the container wherever you want, be it QA,
  your team or even the cloud
• Scale up to 1000s node
• Update with zero downtime

9
Introduction into Puppet

• Puppet is the most popular and de facto standard
  for configuration management with more than
  36,000 organization across the globe with 75 of
  Fortune 100 companies using Puppet. Puppet is
  popular for configuration management in
  automating the delivery and management of hybrid
  infrastructure.
• With Puppet, the system administrators will be
  able to control and enforce consistency across
  infrastructure using a common easy to read
  language. Sharing, Testing and enforcing the
  changes across cloud platforms and data center is
  not going to be breathtaking tasks anymore when
  Puppet is used.

10
Features

• Based on master-slave architecture
• Open-source tool
• Long commercial track record

11
Introduction into Ansible

• Ansible is a general purpose automation tool
  that may be used for configuration management or
  workflow automation. Configuration management is
  an "infrastructure as code" practice that
  codifies things, e.g. what packages and versions
  should be installed on a system, or what daemons
  should be running. Workflow automation may be
  anything from provisioning cloud infrastructure
  to deploying software.
• This article starts with a feature overview, a
  description of how Ansible fits with Chef or
  Puppet, and technical examples of configuration
  management and workflow automation. This article
  will give you a feel for what Ansible can do, and
  the high-level topics for further learning.

12
Features

•  Open source configuration management tool
•  Supports push configuration
• Based on master-slave architecture
• Completely agentless and uses simple syntax
  written YAML

13
Introduction into Nagios

• Although there are many proprietary monitoring
  tools out there to select from depending upon the
  requirement, no proprietary tool can provide the
  peer review, source code modification, and
  version iterations that an open source tool
  provides.
• Nagios is an open source server and network
  monitoring tool that provides all those
  capabilities we discussed above in one package.
  Nagios monitors the servers and network
  devices(in fact i must say any network device
  which is accessible with an IP address can be
  monitored using Nagios) and alerts you when a
  particular service that's being monitored goes
  wrong, and also will alert you when the service
  comes back to normal required state. Nagios is
  capable of doing the following things

14
Features

• Monitors and troubleshoot server performance
  issues
• Plan infrastructure upgrades before outdated
  systems cause failures
• Automatically fix problems when detected

15
Introduction into Selenium

• Selenium is a free (open source) automated
  testing suite for web applications across
  different browsers and platforms.
• It is quite similar to HP Quick Test Pro (QTP
  now UFT) only that Selenium focuses on automating
  web-based applications. Testing done using
  Selenium tool is usually referred as Selenium
  Testing.

16
Features

• Free Open-Source Tool
• Create robust, browser-based regression
  automation suites and tests
• Write test scripts in multiple languages like Java
  , Python, C, Ruby, Perl, Php, JavaScript
• Supports Multiplatform for testing like ios and
  Android
• Easy to build a keyword driven framework for a
  WebDriver

17
Introduction into Chef

• Make the testing and deployment of your projects
  fast, painless, and inexpensive.
• Treating infrastructure as code refers to writing
  code, via any descriptive language, to manage
  server provisioning and configuration process in
  addition to deployment of actual application
  code. It involves adopting automated testing and
  related practices that are already used in modern
  application development, such as version control,
  integration testing, small deployments, use of
  design patterns etc.
• Following those practices and rules means writing
  code to provision and manage the configuration of
  your servers. By doing that you will gain safe,
  repeatable and automated processes.

18
Features

•  Another open-source configuration management
  tool
• Supports multiple platforms like AIX,
  RHEL/CentOS, FreeBSD
• Easy to integrate with cloud-based platforms
•  Active, smart and fast-growing community support

19
Introduction into Splunk

• Splunk is a powerful platform for analyzing
  machine data, data that machines emit in great
  volumes but which is seldom used effectively. The
  fastest way to understand the power and
  versatility of Splunk is to consider two
  scenarios one in the datacenter and one in the
  marketing department. 
• Splunk produces software for searching,
  monitoring, and Splunk gathered all of the
  relevant information into a central index that
  you could rapidly search. Splunk can provide a
  detailed window into what is happening in your
  machine data. Splunk can also reveal historical
  trends, correlate multiple sources of
  information, and help in thousands of other ways.

20
Features

• Store, search, analyze and visualize
  the machine-generated data
• Ingest data in multiple file format
• Create knowledge objects for operational
  intelligence
• Monitors business metrics to get log insights
• Best DevOps Training institute

21
Introduction into ELK Stack

• The products we build often rely on multiple web
  servers and/or multiple database servers. In such
  cases, we often dont have centralized tools for
  analyzing and storing logs. Under such
  circumstances, identifying different types of
  events and correlating them with other types of
  events is an almost impossible mission.
• A single exception condition, somewhere in the
  middle of the system, can be disastrous for both
  the end user and the development team. A user may
  end up looking at a blank page after submitting
  payment for your service, or a large packet-loss
  can occur within your network, resulting in
  stretching a simple 10-minute job into a 10-hour
  headache.

22
Features

• Open Source tool with multiple plugins
• Lightweight tool, easy to deploy
• Perform search in near-real time
• Collects and Analyse logs from an excel file to a
  database or server
•  Active and Supportive discussion forum
