appreciate everyone's advice and help. I am trying to avoid working at Wal-Mart at this point as I am running out of cash and time.. I know I may go for A+ help desk cert, but feel it would be a waste if I could get into something more lucrative like DevOps, esp with my developer background.

Question about blue/green deployments with databases

I'm unable to fully comprehend best method to implement database migration between the two environments. Wouldn't there be data discrepancies between blue and green? Should I be using database replication between these two so the data is always up-to-date? Most blue/green strategies I read deals with applications deployment but lacks on how to deal with data. Any input is appreciated.

What can a DevOps engineer do for mobile & web app development, that Azure App Center can't?

I must not entirely understand the full scope of DevOps, because it seems to me like app center or something similar would do everything it needed to. Am I wrong?

Would love some advice

Hey all,

I am a self-though Python programmer and currently, I am not working as a programmer.
I started learning Python about a year ago and so far I have built various self-projects such as APIs and web-apps using Flask, desktop GUI applications to automate my work (30 people on my team are using it regularly on a daily basis), and more cool stuff.

I have given the option to participate in a 2 months free course that teaches the following:

Methodologies - Branching patterns,
SASS, and Product CI/CD patterns
Release and Lifecycle management.
DevOps Foundations - Bash, Scripting, Networks, Certificate management. Source control - Git, Gitlab, Github. Build & CI tools - Maven, Npm, Jenkins, Gitlab CI, Artifactory. Containerization - Docker, Kubernetes. Public clouds - AWS, GCP.

The course is full-time, meaning I will not be able to work during this time.

At the end of the course, (only in case I finish it successfully) I will be given the option to work for the company that gives it.

The advice I need-
I have a great passion for technology and programming and as someone without a college diploma, I know that my chances of finding a job as a programmer are (not zero but) pretty low and I know for a fact that I want to write code for a living and I strongly believe that I am capable of doing it.

I am at this point where I need to decide whether to leave my current 3 years job and do this course for the chance to be a DevOps engineer.

Do you think it will be worth it? Do you think that DevOps will be the right thing to go for?

Cloudbees CI or Github Actions?

Hey guys.
I have been asked to do an analysis on which one is better among these.
We already have cloudbees jenkins enterprise in our environment.
I have little knowledge on Github Actions.
And security is a priority.

Patch level monitoring dashboard for both RedHat/Ubuntu

Hi guys,

​

I am looking for an open source dashboard that can monitoring and updated patches/packages in RedHat/CentOS/Ubuntu, tools such as fedora's cockpit (which actually fits perfectly) or RedHat's Sattelite...

But I want to here about more (free/prefably opensource) tools

centralizing group information

We're writing an increasing number of inhouse applications that do SSO against a source that only provides us with authentication of the user but doesn't have a way for us to create groups.

In our pre-cloud days we could have used AD to store this information but I don't want to try to make LDAP calls across the internet.

How are people centralizing group information and what applications people have access to that can be available via API? We could probably use a database to do this, but if something already exists I'd love to hear about it.

Team planning

Hello,


I'm working as an OPS & scrum master in medium sized team (\~ 15 people atm, and 5+ to come in january). Apart from the usual .ods/xls how do you guy manage the team planning/agenda?


Is there any decent (free and OSS if possible) software that would make my life easier? I'm also the administrator on our jira & confluence if you guys know of a specific plugin that would also do the trick.


Thanks !

What about a business changes to align on a common platform?

Everywhere I’ve worked has been a mix of physical and virtual machines, on-prem and cloud. Every product had very different development processes for the next product. Most of these companies were mid startup or post startup. As such, few places had any consistency or a common platform to enable product development.

I would love insights from others who have experienced a workplace transition from similar beginnings that transitioned to a common platform.

Any insights into what about the business changes to align interest would be welcome:
size of product development
regulatory requirements
specializations
???

Golang or Python After Powershell

I am pretty a MS sys admin who transitioned into cloud engineering and now Dev-Ops. As I go higher the stack, I see a need to break away from my dependency on Microsoft Technology.

I have been learning more about orchestration, containerization and I a C, playing with Linux and I am pretty good with PowerShell.

Since I am in the world of automation, it makes sense to learn another language to improve my automation skills cross-platform, I have been looking at python for a while, but I seem to be taking a good look at GO as most Server-side automation tools seem to be built with it.

​

I am looking at focusing on one for the new year and will appreciate more insight from people who have had similar experiences.

I'd like to know what differences exist between the two as regards to dev-ops and automation. Thanks

One Sentence for Every AWS Instance Type

Every time I'm starting a new service to run internally or reviewing something we have going, I find myself struggling to find the right instance type for the needs. For instance, there are three families (r, x, z) that optimize RAM in various ways in various combinations and I always forget about the x and z variants.

So I put together this "cheat sheet" for us internally and thought I'd share it for anyone interested. Pull requests welcome for updates: https://github.com/wrble/public/blob/main/aws-instance-types.md

Did I miss anything?

Are developers going to rule the next coming years....

In the long run meaning at least like 5 years from now, do DevOps and SREs roles merge into Software Development, the reason i am asking this is, i am seeing SDE and programmers in general(SQL developers, frontend/backend devs) have already started taking on job duties of DevOps and SREs folks, devs in our org are doing CICD pipelines, IaC, developing custom pages/apps using APIs, watching APM alerts and figuring out performance issues, implementing security best practices etc. I know more than often businesses require dedicated Application and DevOps/SRE teams. But if one has to invest in learning and keeping up with advancements/changes in tech industry, would it help to start leaning towards SDE skillset, when it comes to skilling up and career path. I feel like companies have already started hiring developers with DevOps/SRE skillset (or train them if they are lacking). Just spit balling here, feel free to share your opinions...
