Agenda

• “Enterprise” DevOps• Deutsche Telekom’s DevOps Journey– Pipeline and key components – Jenkins, Chef & Ravello– Best practices & lessons learned

• Ravello’s nested virtualization – VMware & AWS– Live Demo

• Enterprise DevOps: Infrastructure Maturity Model


Enterprise DevOps Debate Rages On

• Enterprise multi-tier architecture

• Enterprise-grade appliances (eg: F5 load balancer)

• Production running on VMware in the data center

• Security

Enterprise DevOps Needs Best Of Both Worlds

• Scale on demand

• Never run out of capacity

• Developer self-service

• Advanced configuration management

• Continuous integration/ continuous delivery

Enterprise Requirements: Rock solid

DevOps Requirements: Extreme agility

Developer self-service for dev/test environments

Dev/QA always provision clones of latest production environment – always run on the latest code

DevOps Tackles Several Issues

How Do You Eat An Elephant? One Bite At A Time…

Auto-provision and deploy full-stack production clones in any cloud on-demand.

Trigger changes using single repository with frequent builds. Automated continuous integration testing on production clones

Manage and maintain complex configurations and frequent configuration changes

How Deutsche Telekom Went To The Next Level Of Agility With Ravello

04/10/2023 13

Enhancing Integration Testing With Ravello

• Integration tests – need to give developers a full environment and not just a small sandbox

• Giving every developer a full environment - a challenge with private cloud

• Public cloud not identical to private cloud – would require the extra mile of “migration”

Ravello Systems, Inc.

Ravello as an extension of the

datacenter


How Deutsche Telekom Used Ravello With Chef & Jenkins

• Created a blueprint of our environment in Ravello

• Chef zero on that environment – it pulls all the latest updates from git

• Spin up mini environments in Ravello using blueprint

• Bootstrap magic happened on the Ravello side


Team Structure


DT Team Structure & Collaboration

• Certified Scrum Master– DevOps team was part of the scrum– Used the same sprint

methodologies in the DevOps team

• Borrowed developers way of developing into the operations world = “classic Dev+Ops”

DevOps should be integral part of the agile team

Software-defined storage

Binary translation to ensure your native

VM remains unmodified

Storage allocation for your VMs in the selected cloud

Fenced L2 network to ensure your static IPs, DNS, subnets

remain unmodified

Online SaaS portal – nothing to download

or install

Private or public cloud: AWS, Google, HP Cloud, Rackspace etc

environments in AWS/Google2. Creating just in time environments

3. Integrations with Chef & Jenkins (if required)



SummaryEnterprise DevOps: Infrastructure Maturity Model


Base Beginner Intermediate Advanced Expert

Enterprise DevOps:

Infrastructure Maturity Model

TestInfra.

Infra. Capacity

Software Delivery Agility

Cross-Team Collab.

Shared, static, scaled down test environments

Shared test environments similar to prod.

Each QA person has access to a static prod. clone

Dynamically auto-provision & deploy prod. clones as needed

Zero-touch continuous parallel testing on prod. replicas

Limited data center capacity. Not fully virtualized

Separately managed private and public cloud environments

Seamless, normalized infrastructure across private & public clouds

Hybrid cloud mgmt. with heterogeneous environments

Fully virtualized data center and possibly colo capacity

1-2 year software release cycle, usually waterfall model

Annual release cadence with some agile processes

Continuous deployment and delivery

Continuous integration – automated builds

6 month or lesser release cycle with fully agile dev/QA

Dev/QA teams send ad-hoc request to IT Ops

Streamlined process for dev/QA to send Ops requests

Dev & Ops teams are fully integrated

Ops team enables self-service for Dev/QA teams

Dedicated Dev & Ops team members

Config Mgmt

Manual tracking using documents

Well-defined change mgmt. process

Scripting to manage config changes

Chef/Puppet etc integrated with infrastructure

Infrastructure managed like code
