PROJECTProduct

Service

OPERATIONS

• Deployment (infrastructure & software)

• Monitoring (Services up/down, capacity)

• Patching, Upgrades, Backups, DR• Making sure – Applications are

running and used by End Users (SLA… some number of 9’s)

• Project Managers• Architect – Design,

POC• Developers • QA Engineers• Usability Engineers

Non-Collaborative Environment in Teams

• Delays in Delivery• Delays in Deployments • Versions, Patches, OS conflicts• Manual Work or semi-Automation

How Innovation Happens? People Issues – New Innovation Happens

New Product Born May be new Frameworks, Techniques Born Systems Administration Job: Many tasks are thankless,

right? Developer/QA Engineer: Do they need to know reverse

proxy? So new Roles introduced To business happen, Different ways of collaboration adopted

(DevOps born) Technology Issues – New Innovation Happens

Programming Languages (many – people are differently skilled) New Frameworks (to save time, to aggregate skills, discipline,

right?) Need was: Focus on Business, why waste time on Technology?

(Cloud Born)

• OS Installations, Patches, Hardening• Application Deployment • Application Patches, Upgrades• Monitoring

• Application• OS (for default attributes e.g. Disk)

• Capacity Planning

Answerable• Business Owners• Application Users• Developers• Sales, QE, UX ….

ALMOST EVERYONE

Developers and OthersDevelopment Infrastructure • Develop Software, Design Software

• No, do not have to worry about production• Checkin/Checkout Code from Repository

• Repositories are managed by others• Build Application – but has special skilled people

Answerable• Business Owners• Application Users• Developers• Sales, QE, UX ….

EVERYONE – DEFINITELY NOT

DevOps Help Manage Software by

• Collaboration Framework

• Automation

Configuration Management Chef, Puppet, Custom Configuration Management using Trac, Subversion

Log Management Splunk and Logstash Google Search Appliance, - Search Appliances

Application Performance Management NewRelic

Monitoring Tools NagiosXI Developed Many Plugins to meet Application Monitoring Requirements Tools around "htmlunit" Java library (simulation of browser user) Auto-Restart Services (using tools like Fabirc)

Deployement Tools "Ansible” (Python and Any other Scripting Programming) "Fabric” (Python Programming) "RunDeck” (previous version was ControlTier – that’s Java, Python or other scripting

Langs) Job Execution

Restart Complete Data Center Applications (Fabric) Support Engineers can pull log files, execute ad-hoc tasks (ControlTier with Liferay Portal)

Infrastructure Vagrant, Docker, vSphare, VPN tunneling (to support remote)
