DevOps (1) * What’s DevOps?

Mulodo Vietnam Co., Ltd.

What’s DevOps?DevOps is … Collaboration of

‘Development’ and ‘operation’. Philosophy, Policy, the way of thinking

Dev: Innovative … Sometimes, it’s disruptive. Ops: Stable … Sometimes, it’s conservative.

What’s DevOps?DevOps is … Collaboration of

‘Development’ and ‘operation’. Philosophy, Policy, the way of thinking

DevOps is NOT …

Automation Build and Release Infrastructure Development System Administration

They are only tools for DevOps.

(BTW) How to think about XXX?

At first, Think about our problems and cause.

1. What is the problem and what is the goal.

2. Think about the cause of for each problems.

3. Set priority for each problems.

4. Get solutions for each problems.

(BTW) Example for bad case.

We have many problems at release timing..I found the solution ‘DevOps’

What’s this?

It will make installation / release operation more easy.

How do we do DevOps?

The way is 1. xxx, 2.xxxx….

It’s NOT clear what is solved by the solution. They haven’t understood what is the solution itself.

What are our problems?Problems.

Well, It works on my machine..

It’s not server, It’s your code.

Sorry, please see the server setting by yourself, I don’t know detail.

We should use same environment local and Live environment, and guarantee easy installation.

GoalsWe should make environment as…

1. Same environment Live and Local.

2. Auto deployment and test to make installation more easily.

3. Auto checking status of the system.

What’s DevOps? (again)Think again about DevOps..

“DevOps is an approach to bridge the gap between agile software development and operations.”

Collaboration mindset of Devs and Ops.

C.A.M.S.

Culture

Sharing

DevOps: CultureRelationship and Communication

Bust Silos and stop finger-pointing

Talk directly

Don’t say “No”

Involve all members

DevOps: AutomationXXXX as Code

Infrastructure as Code Deployment as Code Test as Code

- Machines are good at doing same things many times.

- Make XXXX clearly. Make it automatic.

build, deploy, test, report, monitoring..

- Save time and make tasks efficiently.

DevOps: MetricsMonitor/report status

Build/test report, server status. Find failure

Getting error when it occur. Improve

Analysis status and make proper structure.

Make a plan Find the point to make it better from status, and make new design.

DevOps: SharingShare design of infrastructure. (Ops->Dev)

Infrastructure design and authorization for shell access of servers.

Share changes and new functions (Dev->Ops)

What is the point of this release and what kind of technology we use.

Share metrics.

check status and find failure.

The scope of this study

1. Same environment Live and Local.

2. Auto deployment and test to make installation more easily.

3. Auto checking status of the system.

* ’Gray text’ will be next time…

Preparation for next study

1. Install applications

2. Download box image

3. research and learn of key technology in this paper.
