How do you like to learn new tactics and tools?

I'm investigating ways to improve how systems engineers take on the breadth of their role.

One of the ways I'm looking at this is through learning design.

Looking at microlearning as one avenue for time-poor individuals.

So, my question to you is how do you prefer to learn new tactics and tools?

Pick as many types as you find useful.

How to choose the correct PATH to get into DevOps from Ops...

Hello, my friends

After a long journey and many interviews, I have got a job position as a Junior Application Operations (my first Ops role) and I will start it in September. I have only 1 year 8 months of experience as a Quality Assurance Technician (in the gaming industry/game tester). I love improving myself and I have a great passion to become a DevOps engineer in the future. I would like to read here Advice/Tips from DevOps engineers, especially those who come from an Ops background. I want to know what kind of courses should I follow in Udemy, Coursera, or in other platforms? Tbh, I'm a Business Management student with a master's degree who doesn't have an IT background. Right now I am following Shell/Bash scripting course for myself and I hope this is a good start. I wouldn't want to skip your advice here. Thanks everyone in advance!

Ansible - start at specific role

I have a playbook that only calls roles. This is what it looks like: (there are about 20 roles in it)

---
- hosts: prod1234
roles:
- role1
- role2
- role3

Sometimes, a role fails, and I don't want to start over as each role is huge and I would just like to start at that point or the next one.

With tasks, I know there's a flag for --start-at-task="task-name". Is there something similar I can do with roles?

My current solution is to comment out all the lines I don't need and run it again..

Thanks ahead!

advice to handle work

hey guys, so i was selected as a trainee for the role of devops. This is like my first experience of doing any job and its been almost 2 and a half months since i joined. At first i was told to study git, gitlab , docker jenkins and all those basics related to devops.

after a month i was asked to work on puppet on which i had no clue about.. i did up to puppet installation and some configuration and establishing some connection... i took some time to do this stuff since i had no clue in the beginning and got a lot of errors while proceeding.

so, i was aked to stop it and do another task related to running a flask on docker. i did it and after that i was asked to run flask using tensorflow algoirithm on containers again.. I have know prior coding knowledge and tensorflow is totally different.. i took like 3-4 days and then he told me this is getting compliacated so do work on site realibility engineering. so i stopped tensorflow with docker and started reading about sre.

i had to read a lot of sre related stuff and tried to understand what and why we need it. took me 3 days( could have taken less time) . then i was asked to implement sre in my organization which again i have no clue... i dont even know how to approach and tried for few days and told him i need more time..

again, he told me to chuck it and start looking at prtg which is a network monitoring tool.

today in the daily meeting we had, he told me that i just raise my hands when asked if someone could do a particular task but do nothing about it. And i need to be committed and stuff. he said i dont do anything so why bother giving me a task.

​

i was like shocked and it aint going out of my mind no matter how i try. this is like my first time doing a job and it totally broke my confidence..

i just did what he told me to. i didnt even ask him why we are doing and stuff. i just said ok to him whatever he told. Now he says i didnt do anything.

​

could you guys tell me what went wrong and then how to actually talk, act and stuff realted to being in an office.. all suggestions would be helpful.

thank you

What does the future of DevOps look like?

I'm beginning my transition of Sysadmin to DevOps. Still got a long way to go as I've not used some of the key tools before. What does the future of DevOps look like in the next 5 years or so? Do you think it will become more and more in-demand? Personally I don't think it's going anywhere anytime soon, but as I've got a long way to go to get to my goal it's something that has crossed my mind.

Creating Subdomains on AWS Route 53 with the original domain on GoDaddy

The thing started with wanting to route the traffic through AWS by creating a hosted zone on Route 53 and copy the name servers it generates to GoDaddy. When I checked the existing name servers on my GoDaddy domain before doing anything I found some name servers that belong to Nginx and I'm not sure if adding Route 53's NSs to the existing name servers in general would result in any consequences since the domain has traffic and it's operating!

Also, I want to know which is a better practice, whether to create the subdomains on AWS Route 53 (since I'm using many AWS services) with my domain itself being on GoDaddy or create the subdomains from GoDaddy and just route the traffic through AWS by creating a hosted zone on Route 53 and copy the name servers it generates to GoDaddy.

A serverless platform for running containers globally - feedback?

Hi r/devops

We are validating a new serverless product to deploy and manage containers globally (seaplane.io, the website needs updating). We are looking for feedback.

We found that many engineering teams spend hundreds of hours building and maintaining infrastructure where they could be working on their core applications instead. We aim to solve those problems.

Our platform lets users deploy containerized workloads on a global compute cluster that runs on top of multi-cloud (AWS, Azure, GCP) and bare metal (Equinix, Hivelocity, OVH, etc.) and custom edge. The platform automatically senses your traffic and adjusts the infrastructure accordingly (much like a CDN does for content), scaling horizontally and adjusting where the compute runs to minimize latency.

Besides the compute, we also run a data layer currently supporting Postgres. The DB supports multi-region multi-writer in 400+ locations and is strongly consistent.

The goal is to give engineering and DevOps teams superpowers to build on top of strong infrastructure without worrying about zones, regions, clouds, redundancy, and anything else. The system takes care of all of that while still giving you a granular level of control.

Would you use a system like this? Anyone interested in providing feedback, we would love to hear from you!

Are managed Kubernetes and managed databases worth it for a one-man show?

Hey folks,

Making a webapp by myself and have very little ops experience (mostly do data engineering at my real job but I do some generalist stuff in my spare time like webdev and some backend).

I don't know jack about Kubernetes and was was wondering if paying for managed Kubernetes on DigitalOcean, Linode, or Oracle Cloud (my use case is extremely egress-heavy so I can't afford to use AWS/GCP/Azure) is worth it for me. If not, I was considering using Hashicorp Nomad instead (edit: feedback on this idea welcome).

Will be using Hashicorp stack ops-wise unless I use Kubernetes over Nomad.


Also -- would $15/mo for DigitalOcean's managed databases (because fuck paying for Oracle databases) be worth it for me time-wise? Or could I reliably back up a DB I set up myself with just a cron job?

Looking for Suggestions on git training courses for senior employees that need retraining

I'm looking for git training course suggestions:


The Situation:

I have been tasked with providing a plan for my companies migration from perforce to git; eventually moving our current process into bitbucket. Obviously part of this involves training employees on git, some of which have never used it. We are a small company, so in-house training from other employees would be too much of a time sink to be a viable solution for us.

I've been scouring the internet but i'm having trouble finding unbiased reviews of various git training courses.

Another consideration is that, ideally, there'd be some form of testing/interaction involved. Unfortunately, I'm worried that pure reading/video type courses will result in employees just clicking through it to get it done as quickly as possible and causing a knowledge gap.

What does your company give you for professional development?

Hello,

I'm a position where I can significantly influence the creation of a professional development policy for our company. We're roughly 400 people, majority of which are based in North America but we have a global presence.

I'm curious what everyone's companies are giving them in terms of professional development?

Specifically:

* Do you have a departmental, team, or individual budget? If so, how much?
* Do you have guidelines on how much your company reimburses vs the individual? For example, if someone wants to do some expense certification (i.e. in the thousands of $$), does the company reimburse up to a certain %?
* How does your company determine what is eligible?

There are mixed opinions about this internally so I'm try to collect some data points to justify a pretty generous policy in the spirit of retention. Thanks!

Is it true that the decision to choose a VDS/VPS hosting for a company is more influenced by engineers than managers?

I assume that behind any management decision on choosing a VDS/VPS hosting company, there is a consultation (past or present) with engineers.

How would you answer this Problem Statement

Roughly about a year when I had gotten my cloud cert, and was getting into devops I had an interview for a company for a junior devops engineer position. For the interview I had to explain and answer the following Problem Statement:

· The company is creating its new applications with an event driven microservices pattern.

· The company has already selected AWS

· The company has already selected Jenkins

· The microservices uptime should be 24/7

· The microservices need to be highly resilient, an hour of downtime will cost the company a million dollars in revenue.

Create a design for continuous delivery for these microservices from the branching strategy, through deployment, and the overall stability and scalability in a production environment. 

I don't remember the answer I gave, but I am curious how would someone with a lot of experience in the industry answer this question?

From AWS CloudFormation to Terraform: Migrating Apache Kafka

Every once in a while we found ourselves in a spot where it's no longer up to us — our infrastructure demands a change.


When it comes to Kafka, the high scale and the fact that it's the system bottleneck requires us to be dynamic, responsive and in control, especially when running in production.
But how can we deploy frequent changes, such as: security, hardware, monitoring, etc. and still be stable, version controlled, audited and with a growing demand to user independence?


Check out my new blog post to hear about how Riskified created it's new Kafka infrastructure with Terraform and how we performed our cluster migration with zero downtime and zero data loss.
