Get DevOps done using job tasks and projects based on job tasks defined by professional certification


Overview

Most job descriptons for DevOps roles focus on vendor product offerings (GitHub, Jenkins, etc.).

azure-devopsexpert-230x258-7173.jpg However, this page lists the contributions, achievements, and outcomes from working DevOps (DevTestSecOps or DevXOps), based on Job Task Analysis done for the Implementing Azure DevOps Solutions exam AZ-400 which fuilfills requirements to be designated a Microsoft Certified: Azure DevOps Engineer Expert. Expand all (click on) these high-level statements of contributions:

  1. Design a DevOps strategy
  2. Implement DevOps development processes
  3. Implement continuous integration
  4. Implement continuous delivery
  5. Implement dependency management

Amazon’s DevOps Professional Exam

Compare against the “domains” in Amazon’s AWS Certified DevOps Engineer – Professional Complete Exam: DOP-C00 (since December 2018):

  1. SDLC Automation : CodeCommit, CodeBuild, CodeDeploy, CodePipeline ((22%)
  2. Configuration Management and Infrastructure as Code : CloudFormation, Elastic Beanstalk, AWS Config, ECS, Lambda, OpsWorks (19%)
  3. Monitoring and Logging “ CloudWatch, X-Ray (15%)
  4. Policies and Standards Automation : Service Catalog, Trusted Advisor, Secrets Manager, Organizations, Macie, Cert Manager (10%)
  5. Incident and Event Response : Guard Duty, Inspector Kinesis (18%)
  6. High Availability, Fault Tolerance, and Disaster Recovery : SSO, CloudFront, AutoScaling, Route53, RDS, Aurora, DynamoDB (10%)

The above I also call “processes” addressed by products.

Testing and other habits (values)

The word “testing” is not among the above, perhaps because testing is pervasive, along with other “habits”:

  1. Team Autonomy and Enterprise Alignment
  2. Rigorous Management of Technical Debt
  3. Focus on Flow of Customer Value
  4. Hypothesis Driven Development
  5. Evidence Gathered in Production
  6. Live Site Culture (remediate immediately and drive to root cause)
  7. Manage infrastructure as flexible resources

DevOps practices

But testing is a separate item among VIDEO: 7 DevOps practices as defined by Microsoft’s Sam Guckenheimer:

  1. Configuration management [Course 4]
  2. Release management
  3. Continuous integration [Course 3]
  4. Continuous deployment [Course 3]
  5. Infrastructure as Code [Course 2]
  6. Test automation [Course 5]
  7. Application performance monitoring [Course 7]

All but “release management” track with Microsoft’s curriculum (below).

DevOps Courses

To obtain skill to make contributions listed above, there is a 10-course Microsoft Professional Program (MPP) in DevOps on Edx.org:

  1. Introduction to DevOps Practices
  2. Infrastructure as Code
  3. Continuous Integration and Continuous Deployment
  4. Configuration Management for Containerized Delivery
  5. DevOps Testing
  6. DevOps for Databases
  7. Application Monitoring and Feedback Loops
  8. DevOps for Mobile Apps
  9. Architecting Distributed Cloud Applications
  10. Microsoft Professional Capstone : DevOps

QUESTION: Is AZ-400 the same as exam: Implementing Microsoft Azure DevOps Solutions 70-538 “coming soon”.

Categories for technology management

A dashboard displaying progress toward DevOps implementation would instead be grouped by categories of technology:

A. Security
B. Networks
C. Persistance (storage, databases)
D. Compute (virtual machines)
E. Management (monitoring)
F. DevOps (development to operations)
G. Integration (messaging)
H. Analytics (BI, Visualization, Machine Learning & AI)

The above list is often used to also define organizational boundaries, where technicians report to a manager in charge of each category (such as the department of Networking, etc.). The concern with such an approach is that each category is dependent on others to be setup at the same time. Each of the above needs to be a part of each application.

But traditional enterprise communication tends to be funneled up through category managers rather than directly among workers.

“Agile” teams aim to put skills that address ALL categories into each small team. That’s a tall order considering the staggering number of technologies implemented, especially in companies which have relegated each employee to a very specific role for years and don’t make it easy to hold a job which spans all these categories, even in the course of an entire 40-year career.

Here is where culture, collaboration tools, and automation may help.

PROTIP: The hope is that, eventually, advances in automation would enable small Agile teams to work like a start-up on their own, addressing all aspects of a traditional data center without ceremonies to get permission and clearance through various management ranks. So the futuristic view of the job tasks below would be how to get a computer to do each on its own with minimal human interaction.

But, for now, people are involved in its setup, configuration, and maintenance, so they need to learn the specific skills below, both manually in the GUI and in automation scripts such as Bash, Python, PowerShell, and other scripts.
