DevOps - Evolution in Information Technology and IT Operations

In 2007,  Patrick Debois worked  on a large data center migration as  in charge of testing. During this project, he realized that the frustrations experienced from the constant switching back and forth between the development side and operations side.

Later, in 2008 during an Agile conference held in Toronto, Canada, Andrew Shafer tried to put together a meetup session entitled “Agile Infrastructure” which did not happen. But, Patrick  hunted him down at the conference and had a talk with him.  They formed a discussion group on how to solve the divide between development and operations.

 In June of 2009, John Allspaw and Paul Hammond gave a talk entitled “10+ Deploys a Day: Dev and Ops Cooperation at Flickr.”

Patrick happened to watch the streaming video of that presentation and he realized this was a good  solution. He organized the event  names "DevOpsDays",  in the last days of October in 2009. This event was a success with practitioners from both fields and sparked lively debates over Twitter. On Twitter,  the hashtag DevOps became popular. From then on DevOps practices as well as tools built to aid these newly forming teams in organization emerged. DevOps had managed to achieve a grassroots following that was trying to use the new method of interaction between Dev and Ops teams.

In March of 2011, Cameron Haight of Gartner presented his forecasted trajectory of DevOps over the next few years and this increased visibility for DevOps practices and tools. Enterprises of all sizes began to adopt these new practices. DevOps had officially caught on as a big thing since Agile for the IT industry.

What is DevOps?

What is the Dev and what is the Ops in DevOps?

Operations responsibilities

IT buying
Installation of server hardware and OS
Configuration of servers, networks, storage, etc…
Monitoring of servers
Respond to outages
IT security
Managing phone systems, network
Change control
Backup and disaster recovery planning
Manage active directory
Asset tracking
Shared Development & Operations duties
Software deployments
Application support


Now a day  big serves are bought, virtualized and used as needed. Cloud hosting eliminates  the need to buy servers. Now cloud space is to be bought.

What part of the “Ops” duties are done by developers?

Be involved in selecting the application stack
Configure and deploy virtual or cloud servers (potentially)
Deploy their applications
Monitor application and system health
Respond to applications problems as they arise.


Developers who take ownership of these responsibilities can ultimately deploy and support their applications more rapidly.

DevOps processes and tools eliminate the walls between the Dev and the Ops teams and enables more agility for the business. DevOps  can enable the developers to potentially be responsible for the enter application stack from OS level.

DevOps lets the operations team focus on the infrastructure and IT policies while empowering the developers to exercise tremendous ownership from the OS level and up. Developers can own the application stack, build it, deploy it, and  support it. Development teams can use infrastructure on self-service basis independent of a busy centralized operations team. DevOps enables more agility, better efficiency, and ultimately a higher level of service to their customers.

The Pursuit of Productivity in  the data privacy and IT industry

In the data privacy and IT industry, there are processes set in place that allow for constant improvements in productivity and efficiency. Generally, there are three approaches that have been in practice by the IT and data privacy sector - DevOps, PrivacyOps and AIOps - What  are these approaches to productivity and how do they differ from one another?

SRE (Site Reliability Engineer) vs DevOps: What’s the difference?
Alex Golub
Jul 21

SRE (Site Reliability Engineering)) is  implementation of DevOps  objectivesa by finding and deploying automated approaches to work previously carried out by an ops team.

SREs are software engineers with a skillset focused on deployment, configuration management, monitoring, and metrics. The software developed by SREs provides a bridge to the developer team to ensure that the DevOps team can deliver a product/system that is updated, managed, and monitored effectively.”

SREs are “strong platform/cloud engineers with a good background in reliability engineering and a passion for ensuring that the Product is ALWAYS available, stable, and performant whilst understanding and enabling fast reliable releases to production.”

The SRE the role requires  knowing about “tools and processes that ensure that a system/platform/solution and its architecture is running as expected and providing the right functionality.”

DevOps Overview

The Oracle Cloud Infrastructure (OCI) DevOps service is an end-to-end, continuous integration and continuous delivery (CI/CD) platform for developers.

Use this service to easily build, test, and deploy software and applications on Oracle Cloud. The DevOps build and deployment pipelines reduce change-driven errors and decreases the time customers spend on building and deploying releases. The service also provides private Git repositories to store your code and supports connections to external code repositories.
