Ops? You’ve said Ops?

• Ops stands for “IT Operations”• Ops are responsible for the smooth functioning

of the infrastructure and operational environments that support application deployment such as:

• network infrastructure; • server and device management; • computer operations; • IT infrastructure library (ITIL) management; • help desk services for an organization.

The Definition, finally!

Put simply, DevOps is the culture, principles, and processes that automate and streamline the end-to-end flow from code development to delivering the features/changes to users in production.

CD Processes and Practices

• Monitor everything• Put all production artifacts into version control• Developers to continually integrate new changes• Automated tests• Automate the configuration of environments• Code Review• Release smaller changes• Institute blameless postmortems• Use dashboards to promote communication

#

Monitoring tool: Elastic Stack

• Reliably and securely take data from any source, in any format, and search, analyze, and visualize it in real time.

#

Elastic Stack Components (Kibana)

• Kbania is a visualization tool for data on top of elasticsearch.

#

Elastic Stack Components (Elasticsearch)

• Distributed, JSON-based search and analytics engine designed for horizontal scalability, maximum reliability, and easy management.

• It centrally stores your data so you can discover the expected and uncover the unexpected.

#

Elastic Stack Components (Logstash)

• Is a data processing pipeline that ingests data (events and logs) from a multitude of sources simultaneously, transforms it, and then sends it to Elasticsearch.

• As data travels from source to store, Logstash filters parse each event, identify named fields to build structure, and transform them to converge on a common format.

#


• Example of Logstash Configuration File:

#


• Assume the following log line from Apache:127.0.0.1 - - [11/Dec/2013:00:01:45 -0800] "GET /xampp/status.php HTTP/1.1" 200 3891 "http://cadenza/xampp/navi.php" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:25.0) Gecko/20100101 Firefox/25.0

• Result of the parsing:

#

Elastic Stack Components (Beats)

• Platform for sending data from edge machines to Logstash and Elasticsearch.

• Installed on your servers as lightweight agents and send data to Logstash (for transformation) or Elasticsearch.

#

Elastic Stack Component (X-Pack)

• Extends Elastic Stack:• Security• Alerting• Monitoring• Graph• Reporting
