Looking for an Business Partner with IT experience

Hi,

I am in the process of development of this app idea and looking for an experienced IT business partner to handle the technical side of things. Both of us will be cofounders in contract and I'll bear the costs of the project. Please let me know if anyone is interested.

What is DevOps | Easy Explained | How is DevOps used in Netflix?

So, what exactly is DevOps? So, in this article, I'm going to answer that question from a perspective that you might be able to relate to, assuming that if you're reading this, you've heard the term DevOps somewhere and it sounds interesting to you, but you want to get past the theory and the political agenda and the eight-hour dissertations and the people trying to sell you stuff and just figure out, what do you actually do for DevOps? more

Got a year of spare time to learn. The catch: I don't have any internet access.

Every month, I "work" for 18 days at a military base and then get a 10-day holiday where I get to go home and have access to the internet. The 18 days I spend at the military involve me siting at a computer desk working on administrative stuff for 1 hour, then spending the other 6 hours doing nothing. I'm already two months in and I feel I've forgotten some of the CS stuff I learned in my MIS degree.

Anyways, I want to get into DevOps so I was thinking of buying some PDF textbooks, putting them on a USB stick and then reading them on the computer at the military branch I work in during those 18 days.

The problem is I don't know what's better for me long term: slowly studying CS during this whole year, or learning DevOps so I can find a job when I finish my service by the end of the year.

1. CS route: I would study from the books mentioned on the highly recommended teachyourselfcs site. Thing is, I don't know if I need to know all of this if I want to work in a DevOps role or even a backend role?

2. DevOps route: I've come across the DevOps roadmap recommended often on here and was thinking of buying books for each category (Python, Linux Admin, Networking, IaC, Docker, Cloud). This great comment mentioned by u/jacurtis perfectly illustrates what I mean.

My concern is how feasible would it be to learn these things without internet and without a code editor to practice on for 18 days/month. I'm literally running on stock windows pc with no internet or admin priviglies at the place I'm working in, hence the need for text-based pdf books to study from.

I need some guidance on what you guys think will be good for me in the long term. Which route should I take? Or should I combine a little of both? How do I go about doing this knowing I have 3 weeks no internet access/1 week internet access per month? Please help a lost soldier out...

Note: I have some programming background in C++ and Python, as well as some frontend internship experience. I also took several CS and IS courses in my MIS degree.

Kubernetes, Jenkins, Docker/Packer, and dynamic kickstart server.

I'm running a bare metal k8s cluster with Jenkins as my CI/CD tool and using Proxmox as a hypervisor for all of the x86 nodes. I'm trying to use Packer to build a Gold Image for immutable infrastructure and Terraform and whatnot. It all works by hand in that if I log on to a node that has Packer installed, I can type packer build template.pkr.hcl and a few minutes later, I have my image template ready to go on my Proxmox server.

However, now I'm trying to migrate the code to Jenkins. I'm using a containerTemplate so that I can use the hashicorp/packer Docker image to perform the build. While I could simply install Packer on each of the nodes, I'd rather not. I'd rather just utilize Docker images for my build steps.

The problem is that when Packer runs, it stands up a tiny webserver to serve the kickstart file. My kickstart file is dynamic (in that I generate the ssh_password on every build and have to inject the encrypted password into the kickstart file so the provisioning step can run and get the cloud-init packages installed and so on). But, that tiny webserver not only has a dynamically assigned port number, that tiny webserver ends up attached to the service CIDR address of the k8s-instantiated Docker image which means that Proxmox doesn't have a route.

For instance, Proxmox is running on 192.168.121.5, but the kickstart server is running on 100.65.20.2 which means that Proxmox doesn't have a route into the service CIDR (nor do I want a route for obvious reasons).

Has anybody else faced this same problem and solved it?

One option that I've considered is that I can dynamically update the kickstart file, upload it to a Nexus repository server, inject that Nexus server URL into the pkr.hcl boot command as an environment variable, and delete the kickstart file upon completion, but I was hoping there might be a more elegant solution.

How would you setup multi AWS environments for your team?

I have the privilege of setting up AWS infra for my team. We currently have everything in one account and my initial thoughts are to make this catch-all account a service account and then have it reach into a dev, stage, and prod aws account for deploys. Are there better patterns?

Alternatively, should I just use the control tower account factory capability of terraform mentioned here? If you have used it, please could you chime in? Or if you've done something similar with AWS CDK, I'd like to hear from you too. Thanks!

Being able to design right cloud solution for given software

I am software engineer with 2+ years of experience. I wear multiple hats in projects I work on and one of those hats is designing cloud architecture based on technical requirements and deploying project based on that architecture. The problem is that I have a hard time designing such architectures, as I don't know how to choose a right solution from a right vendor for implementing a specific requirement in project. For example: I have to implement image/video upload & retrieval - I search for the services and learn about the following possible options:

- Use Cloud Storage
- Use AWS S3
- Use DigitalOcean Spaces
- Use AWS EC2 VM as file system for those files
- Use Compute Engine VM as file system for those files
- Use DigitalOcean Droplet as file system for those files

but I can't choose a right solution which will be scalable, reliable, and affordable (important!) among all those vendors and all their services, and hidden costs of each service which becomes visible after scaling up.

What specific skills do I have to learn? What am I doing wrong?

How do you use Go in your DevOps job?

I'm pretty proficient with a few languages, however Go has recently caught my eye and im learning the basics.

I know they say Go is up their with Python as the big language for DevOps Engineers.

What are some ways you are using Go in your job?

(I know popular tools like Terraform, Docker and k8s are written in Go. I'd like to exclude these, as it isn't very relevant what language these tools are written in unless you are a contributor to those projects)

Developing is hard

I am slowly starting to appreciate all the apps and websites i use more and more lately. The fact that everything works almost perfectly without breaking is very impressive. Reddit is a huge feat. The iOS is a remarkable piece of technology. I appreciate every single one of you. Our work is literally shaping the world.


Good stuff everyone.

Today I learned "Signoz architecture is more simpler than Prometheus+Cortex"

One of my AWS client's (a gaming company) was searching for APM and decided to do POC with DataDog, after reading /researching a couple of days I understood DD has more complex & heavy pricing. So I turned towards open-source mainly Prometheus and Grafana, but since it isn't the case of "one-size-fits-all" I was still diving deeper in open source and came across Signoz an open-source APM based on OpenTelemetry component. If anyone has used Signoz please let me know your views about it.

What do you do (as a junior) when you're new and cannot learn the systems without help but your entire team is too busy?

I'm the only junior in a team of nearly 10.

Been here for almost 2 months on my team. I've learned a few things about our systems. I was new to the vast majority of the technology. I've had about 4 short sessions 1 on 1 for anywhere from 10 mins to about an hour. The problem is that the complexity of this system takes at least 5 or 6 months (according to team)...and that's for more experienced people than myself. And no one really tells me to do anything or helps unless I ask and manage to find a free slot in their schedule.

I feel like I'm not doing much a lot of the time. I look over the ticket I'm working on but I've reached the farthest point I could get to without guidance. The other team members are working on much more important things than this ticket.

At this rate, I'll never learn enough to contribute, learn our systems and function independently. Not sure what to do.

EC2 vs Lightsail

If my plan is to have a Wordpress blog with 20-40 multi sites each with a few plugins, do I go all in on EC2?

The first multisite is already bogged down on crappy $7/mo shared hosting. Is lightsail going to be enough of a step up today? Is it going to be very expensive to switch from lightsail to ec2 in 5 months with 5 or so multisites up and running?

Can somebody link me to an article as to how I can learn about server usage? They talk of on demand hourly rates and network performance in gb’s used.


Hoping to learn a bit today! Love resources if you can point me the right direction!

Bachelors in IS or CS

Hey all,

I'm looking at continuing education. I currently have an Associates in Computer Systems Administration and have been a DevOps Engineer/SRE for the past 5 years. I was wondering if I should continue down the IS path or branch out and go down the CS path.

I want to continue working in the SRE/Cloud space but I do know my shortcomings are around development (Python, Go).

Would love to hear everyone's feedback.
