SDLC Automation

SDLC Automation is the most asked domain in AWS Certified DevOps Engineer-Professional Exam and it covers 22% of the exam. This domain mainly revolves around automating the Software Development Lifecycle.

SDLC domain supports one of the core principles of DevOps of removing the difference between developers and operators with the intent of performing automation as much as possible. The main idea behind Automation is to set up, configuration, deploy, and support infrastructure and the applications that run on it. With the help of automation, you can set up environments more rapidly in a standardized and repeatable manner. The removal of manual processes is key to a successful DevOps strategy. The advantage of automation is critical to realizing the full benefits of the cloud.

Continue to read further and know more in this blog on - SDLC Automation: Everything You Need To Know, to get an overview and to understand the benefits, services, and concepts that plays important role in SDLC Automation.

Want to Find A More Niche IT Career.. Considering Switching from Software Development to DevOps.. Non-Networking/Non-Operations Background.. How Hard And Long to Achieve?

I am getting pretty burned out trying to prepare for full stack web job interviews.. I spent a majority of my career doing desktop development. Some of my skill sets have become dated, although I really am picking up all the new technologies easily and have migrated to web development. I have spent the last 3 years developing web software and learning a lot of the technologies. However, I am getting so burned out. Whereas back in the day , there was a lot of jobs separated by skills, back-end, data architect , front-end, web designer, etc , these days it seems like with full stack web development they want you to be a master at every area in development. Even some places want you to be a DevOps/WebDesigner/Database Dev. Just nutty requirements. Companies are trying to cut costs thinking they can find a one-fits-all unicorn web dev. I think a lot of people BS their way in and probably are more skilled in one area.

​

I am just sick of it. I like DevOps in that it is focused on specific tools and skills and that I can fine-grain what I am learning. As well, web- development has become so saturated. So many people who were plumbers, hairstylists, every kid at the shoe store go to a 3 month bootcamp and then start listing themselves as full stack web developers. The field is so saturated and even many web jobs are being off-shored now everything is virtual. It really has become a rat-race and trying to master javascript frameworks, back-end frameworks, database frameworks, etc is really over-the-top. It takes away the joy having to spend so much time learning every kind of framework, etc.

​

Basically, I am looking to switch to a field in IT where I Can utilize my 20 years of software experience and smaller amount of systems knowledge (use to spend time with Windows machines). Do you think DevOps is pretty lucrative field that with maybe 4-5 months of long hours of study that I can break into? I was thinking about dumping all my React and javascript stuff I don't even like studying and jumping into learning networking, linux and going for AWS and Azure certs. I feel like DevOps is in high demand, pays well and is something i can pick up. I know there are different types of DevOps. Do you think I can pick up a lot of requirements to get into a junior (maybe even mid) position with rigorous study (like 70+ hrs a week) for the next 3-4 months?

​

I am just burned out with web development and don't love it. I just feel I may need 6 months or more to prepare for full stack web dev interview and its not where I want to go in life.. I lost my dental software business with Covid (it stopped making enough money to survive) and have not had to interview in 15+ years. Also, I am still learning the ins and outs of interviewing at these big corporations.

Being a corporate web programmer is not what I desire. If I could go back in time I would probably pick a different profession like AI, ML or some other area. But, in addition to not having a deep foundation in algorithms, data learning, etc. I also would like to eventually get into consulting. I figure DevOps, Cloud engineering and getting into a solutions architect role could be a pathway to that. It would be great to learn about how the SDLC , infrastructure and architecture of a corporate software system operates. The knowledge I could learn in DevOps I think would be valuable too. I've also found I am much more fascinated with handling servers, managing infrastructure, networking and systems related stuff than programming in Javascript. Web browser programming utterly disgusts me. The only exception is programming in Blazor Web Assembly (C# on the front-end), but I don't see that as being a lucrative career option. I do like back-end programming, but a majority of web jobs require considerably more front-end stuff and even web design.

​

I

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.

​

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
