DevOps is the bridge between the development and operations excellence

It is an extension of the lean and Agile principles, which streamlines and helps rapid deployments

DevOps

"DevOps" is meant to denote a close collaboration and cross-pollination between what were previously purely development roles, purely operations roles and purely QA roles

DevOps Adoption

In organizations, many different settings may be in place like different tools for developers and operation teams, different working models and objectives

“DevOps defines the process which streamlines software development with feedback from production, thus improving the product life cycle”

DevOps Aspects and Inspirations:

ᗍ Culture: Get rid of cultural barriers

ᗍ Automation: Reduce the mundane tasks and automate

ᗍ Measurements: There must be well defined metrics with incentives

ᗍ Sharing: There must be a culture to share ideas, tools

Challenges

In traditional projects, software is specified and then programmed in stages and not in iterations. Very often the specifications change, bugs filed and it becomes difficult to align with the original project outline For software, it’s a long journey to the production

With Agile, programmers and testers became Developers and with DevOps, developers and operations became DevOps




The biggest business benefit of switching to DevOps is the increase in customer satisfaction.

DevOps Building Blocks

DevOps is about constant feedback and reducing the risk of release through improvement in flow of features from inception to their availability

This can be achieved by reducing the batch size of releases. Instead of deploying ten features every 3 months, better deploy 1 every few weeks

This will introduce new feature sooner in the market and also ease out the deployment in production with lesser chance of critical issues




Why DevOps is becoming a Pivotal Factor in New Data Centers?

DevOps is a software development method that uses automation to focus on communication, collaboration and integration between software developers and IT operations specialists.

The goal is to maximize the predictability, efficiency, security and maintainability of operational processes.




Tools for DevOps

1. Atlas: In addition to configuration management and service discovery, Atlas provides visibility into infrastructure, including servers, containers, and virtual machines. Atlas enables

2. Chef: Chef turns infrastructure into code. Chef helps to build, deploy, and manage your infrastructure so that your infrastructure becomes as versionable, testable, and repeatable as application code.

3. Docker: open platform for developers helps to build, ship and run any app, anywhere.

4. Puppet: used to deploy new servers, virtual machines, or services.

5. Saltstack

6. ScriptRock GuardRail

7. Splunk




Benefits of DevOps for IT and Business

Companies that incorporate DevOps practices get more done, plain and simple.

Technical benefits:

ᗍ Continuous software deliveryᗍ Less complex problems to fixᗍ Faster resolution of problemsᗍ Reduced Deployment Failures and Rollbacksᗍ Reduced Time to recover upon Failure

Business benefits:

ᗍ Faster delivery of featuresᗍ More stable operating environmentsᗍ More time available to add value (rather than fix/maintain)




DevOps Skills

DevOps is a bridge between the Operations and Development. The DevOps team needs the knowledge about both the environments

The team should understand the complexities of Enterprise setups including server farms, network devices and layouts, storage and BCP plans

It is also about development life cycle of a product, code reviews, deployment complexities and release changes

Scale of Infrastructure

ᗍ There can be thousands of servers, with complex network connectivity

ᗍ Scalable Architectures with various services and Application stacks

ᗍ There can be software's from multiple vendors and with different configurations for each team

ᗍ Some old code which now no one knows about
