- Getting Involved
- About the Program
- Responsible for systems (typically servers) running code, applications,
- Keeping applications running (they crash, sometimes a lot)
- Updates, Security
- Monitoring, Logging
- Automates significant amounts of work with infrastructure
- This enables a small team to administer hundreds or thousands of servers
- Involved in infrastructure architecture and decisions
- Can be involved in QA/Development work as well
- Responsible for creating the platforms code is run on
- Work at a lower-level
- Generally make infrastructure decisions for others
- Often have expertise with some particular sub-system (networking, filesystems, etc)
- Not necessarily on-call, but can be
- Sometimes intermixed with Systems Administrators who want Engineer in their title
- Mix of Systems (Operations) and Development work
- Involved where the application and its platform meet
- Responsibilities include a mix of both Ops and Dev, usually:
- General infrastructure/automation
- Continuous Integration and Testing
- Developer Environments/Workflow
- Often on-call
- SRE and DevOps Engineers share the same foundational principles
- SRE is viewed as a “specific implementation of DevOps with some idiosyncratic extensions”
- SRE was originally created at Google as a process to improve managing their services
- Most large tech companies now follow SRE processes
DevOps can mean a lot of thing to a lot of people, and in the grand scheme of Computer Science it’s a relatively new term. One definition you can always get a way with is this:
DevOps is a field which takes skills from Software Development and Operations Engineering to create and run applications more effectively.
TLDR: Development + Operations == Better Services
DevOps defines 5 key pillars of success:
- Reduce organizational silos
- Accept failure as normal
- Implement gradual changes
- Leverage tooling and automation
- Measure everything
- In a pre-DevOps world the jobs of Devs and Ops were separate:
- There was a clearly defined and relatively standardized interface between the two.
- Workflows were slower, meaning there was more time to troubleshoot and debug.
- In a Post-DevOps world we have a new hybrid job:
- Software is released faster via Agile Development.
- Larger scale services means companies need many identical servers, spawning Configuration Management tools.
- Devs need to know ops skills to better tests their projects and to anticipate issues when it comes to deploying the application.
- Ops need to know development skills to minimize wasted resources and to improve security of the applications and the servers those apps run on.
TLDR: Couch to DevOps in 1 school year
- DOBC is a free education program offering:
- Mentors teaching DevOps related tools and concepts.
- A challenge for anybody willing to put in the effort.
- One-on-one Apprenticeship.
- Hands-on training and lectures
- Free and Open Source course materials!
DOBC will meet about twice monthly for in-person lectures and hands-on activities. All course materials are available from the start for those who are self-guided and want to work ahead.
Check the schedule for more information.
- DevOps BootCamp is not:
- A for-credit OSU class
- A Student job
DOBC is a free course for all types of students. If you want to attend online, in person, or just want help on IRC you are welcomed and encouraged to participate.
While the course does not go on your academic transcript, the skills you learn and the course itself can (and should) go on you Resume. The many benefits of DOBC will be discussed and brought up throughout the course.
- DOBC was created because the OSU OSL:
- Merged with the school of EECS.
- Wanted to help students meet Company demands and expectations of recent graduates.
- Needed to bridge the “Skills Gap” of the OSU EECS curriculum.
- Wanted to build a DevOps Learning community.
The OSU Open Source Lab has become part of the OSU School of EECS so this program was created in an effort to contribute directly to the learning community by sharing our knowledge in a useful and constructive way.
In teaching OSU Students (and anybody else who wants to learn) we hope to give more people a chance reach employment in the growing and exciting industries around DevOps.
- You will Learn:
- Linux systems
- Software development
- Tools and why they matter
DOBC focuses on teaching conceptual understanding over wrought memorization of commands to get a particular job done. This means that we will be addressing the why and what am I doing much more often than the how and what do I type.
- You will build:
- Functioning applications on the cloud
- Cloud infrastructures
The tools of industry change every year, but the way we tackle problems changes much more slowly. DOBC focuses on learning how and why in problem solving over the what. That doesn’t mean we won’t mess with code and servers, it just means we’ll talk about what and why we’re doing something too!
- The teachers of DOBC include:
- OSL Students
- OSL Faculty
- Guests from The Industry
The OSL employs ~20 part-time students who are all equipped to answer questions and teach this course. Many of your lecturers and activity assistants were once DOBC students and are now gainfully employed by the OSL.
We also bring in guest speakers in from time-to-time to talk about a specific topic. These guest lectures may not be as interactive as other lessons, but meeting and talking with industry experts is a valuable experience you should take.
We also encourage asking questions and students contributing to the course. If you learned something interesting share it with your peers and during class. At the very least ask questions; you’re not the only one who’s confused.
- You get out what you put in.
- DOBC is not meant to be easy. Stick with it, persistence is rewarded.
- Student Benefits:
- A free education on industry topics, tools, and concepts
- Student Responsibilities:
- Show up if you can, keep up if you cannot, put forth effort, and don’t forget to have fun.
- Give us feedback.
- There will be a survey you, should take it.
- Honesty is the best policy.
- Linux Basics and Environment Setup
- Operating Systems
- Documentation, and Getting on Slack & IRC
- Shell Navigation
- Users, Groups and Permissions
- Packages, Software, Libraries
- During the winter term, we’ll be covering additional lessons each month (likely in 2 hour blocks)
- Lessons will likely happen during the week in the late afternoons (day, time and location TBD)
- Registrations for each monthly workshop will be required for attendance
- Depending on the level of interest, we’ll continue doing each lesson through the Spring term
