How does your team promote your products? Which channel?

Hi all, I’m curious about how web developers and their teams promote their own products or tools.

Do you mainly use email marketing to reach your audience or do you rely more on social media, blogs, or other channels?

Help! My side project is burning cash on Google Cloud SQL 😅need a free database host

I’ve deployed my machine learning web app on Google Cloud, but I’ve started incurring charges. I’m now looking for a free alternative for hosting.

The app consists of:

* A frontend hosted on Vercel
* Two APIs (one for data processing and another for connecting to the ML .pkl model)
* A MySQL database that stores all the data used by the APIs

From what I understand, the costs are coming from the MySQL database hosted on Cloud SQL. It’s already cost me around $3 in just a week, which is not sustainable since the app doesn’t generate any income.

I’m looking for a free MySQL hosting option (or something similar) that can work with my current setup. I’ve tried alternatives like CockroachDB and Firebase, but I found them a bit confusing. Before committing to another platform, I wanted to ask for recommendations.

Thanks in advance!

We’re building a small fintech app – AWS vs Azure? Need advice on structure, security, and cost

Hey everyone,

I’m part of a small team building a mobile app (iOS & Android) for home financing. The app’s purpose is to let users create a profile, go through a credit evaluation via a third-party integration, and eventually manage parts of their financing process in a secure and compliant way.

We’re at the stage where we need to decide on the overall backend and authentication setup, and I’d really appreciate some insight from people who’ve been there before.

Here’s what we care about:

- Keeping costs low, especially early on (MVP phase).

- Minimizing our data responsibility – ideally, we don’t want to directly handle sensitive personal data due to GDPR.

- Maintaining a secure and scalable architecture.

- Using something our team (mostly .NET/C# devs) can work with comfortably.


We’ve been comparing three main approaches:

1. AWS (Cognito + API Gateway + Lambda + DynamoDB)

- Super low cost for early usage (Cognito free up to ~10k MAU, Lambda pay-per-use).

- Easy to scale, and no server maintenance.

- .NET 8 works great with Lambda now.

- Slightly less integrated if we ever need to connect with Microsoft services later.

2. Azure (Entra ID B2C + Azure Functions + CosmosDB)

- Strong enterprise-level security and compliance.

- Better if we end up needing Office 365 / Power BI / MS ecosystem integration.

- B2C is free up to 50k users, but setup and maintenance seem more complex.

- Costs and admin overhead might ramp up faster.

At this point, I’m leaning toward AWS because it seems cheaper, easier to maintain, and gives us a clean, serverless architecture with minimal ops.

But I’d love to hear your experiences:

- Have you built similar apps (fintech, identity-heavy, serverless)?

- How have you handled user authentication and third-party integrations securely?

- Any surprises or gotchas you’ve faced with Cognito, Entra B2C, or Auth0?

- Would you choose differently if you had to start over?


Any advice, lessons learned, or real-world insights would be massively appreciated 🙏

Thanks!

No Kubernetes experience, Am I cooked?

Currently in a role which everything is deployed via AWS ECS Fargate containers. I have been supporting these applications for a little bit now. There is not a TON of net new things to work on and learn. Just browsing roles or Job Denoscriptions I am seeing a ton of companies asking for Kubernetes experience. It seems like 80-90% of the roles want this for a mid level engineer. Are this many companies actually using Kubernetes, whether it be AWS EKS or Azure AKS, or googles Kubernetes offering.

having no experience and frankly, Kubernetes for my current work application is overkill. So I wouldn't be able to gain on the job experience. That said, am I cooked in this Job market(outside of the Market already being doo-doo in general). I have come across posts of folks who study for the cert but seem to not have hands on experience - which I DONT want to go down this route, not sure what the though process is on that lol.

Thought about doing it on my spare time but kids and wife take a good majority of my weekend, and not sure what the best method is to learn about Kubernetes and which learning method would be the most effective which the community recommends.

Octopus Deploy vs speed/safety tradeoffs

One of the biggest tensions in DevOps is shipping faster vs shipping safer. Octo⁤pus Deploy gives us approvals, audit logs, and runbooks, but those can also slow things down if overused.

How do you balance speed and safety in Octo⁤pus Deploy? Feature flags? Progressive deployments? Manual approvals only in certain environments? Would love to hear how other teams approach this.

Apple's new container runtime vs Docker Desktop

Hi everyone

I was curious how Apple’s new container system compares to Docker Desktop, so I ran some benchmarks.
I tested CPU, memory, disk I/O, and startup time.

|Category|Docker|Apple|Units|
|:-|:-|:-|:-|
|CPU 1 thread|10939.81|11080.05|events/s|
|CPU all threads|53881.70|55415.57|events/s|
|Memory|81634.45|108588.00|MiB/s|
|Startup time|0.21|0.92|seconds|

Full charts and results, are available here: Full Benchmark

Let me know if you’d like me to run additional tests

DevOps engineers: What Bash skills do you actually use in production that aren't taught in most courses?

I'm a DevOps Team Lead managing Kubernetes/AWS infrastructure at an FDA-compliant medical device company. My colleague works at Proofpoint doing security automation.

We've both noticed that most Bash courses teach toy examples, but production Bash is different. We're curious what real-world skills you wish you'd learned earlier:

* Are you parsing CloudWatch/Splunk logs?
* Automating CI/CD pipelines?
* Handling secrets management in noscripts?
* Debugging production incidents with Bash one-liners?
* Something else entirely?

What Bash skills have been most valuable in your DevOps career that you had to learn the hard way?

Do I build "api-core" layer as an always-on container (App Runner / Fargate) — or as event-driven Lambda functions?

Such as user auth, billing, usage. Think core business logic that my webapps will call about my customers (B2C/B2B)

Where the api-core is like an internal service, with its own ci/cd pipeline

Taking the CKAD exam this week after CKS and CKA. Any advice?

Hi All!

I am taking the CKAD exam next week. I was urged to be a KUBERSTRONAUT by my co-workers. Any advice for me? I am yet to do the Killrsh practice tests (I want to do it just before the exams).

My past experiences with the exam have been that the questions are really not what you expect. Is it going to be the same with CKAD? I am going in with just a week's prep so I am feeling a bit unprepared. Should I work for another week?

Any particular topics that I should focus on?

Thanks in advance for all your help!

Does every DevOps role really need Kubernetes skills?

I’ve noticed that most DevOps job postings these days mention Kubernetes as a required skill. My question is, are all DevOps roles really expected to involve Kubernetes?

Is it not possible to have DevOps engineers who don’t work with Kubernetes at all? For example, a small startup that is just trying to scale up might find Kubernetes to be an overkill and quite expensive to maintain.

Does that mean such a company can’t have a DevOps engineer on their team? I’d like to hear what others think about this.

Is there a way to get notified when a CVE in your container image is actually being exploited in the wild?

Getting tired of patching every theoretical CVE that scanners throw at us. Half of them never see real exploits but still create noise and patch fatigue.

Anyone know of tools or feeds that can tell you when a CVE in your container images is actually being exploited in the wild? Not just CVSS scores or theoretical impact, but real threat intel showing active exploitation.

Would love to prioritize patches based on actual risk instead of just severity numbers.

How do you write your first post about a new habit-building app?

I’ve recently finished developing my first product app that helps users build habits and achieve their goals step by step. Since I don’t have prior marketing experience, I’m planning to start with zero-cost marketing and rely mainly on organic posts. My goal is to share the story behind the app and invite feedback, but I’m unsure how to write that first post without sounding like I’m trying to sell something.

For those who’ve launched a product before, how did you craft your first post to make it feel authentic and engaging? What elements or structure helped you get genuine feedback instead of just promotional nois

Stuck between honesty and overselling.

I’ve been working in DevOps for about 12 years now. Covering most aspects over the years: build and release management, infra provisioning and maintenance (cloud and on-prem), SRE work, config management, and a bit of DevSecOps too.



Here’s where my dilemma starts. Like most DevOps engineers in large orgs, I haven’t personally set up every layer of the stack. For instance,

* I know Kubernetes well enough to manage deployments, troubleshoot, and maintain clusters, but I wasn’t the one who built them from scratch.
* Same with Ansible, I write and manage playbooks daily, but I didn’t originally architect or configure the controller host.
* Similar story with Terraform, cloud infra setup, and WAF/network administration, I understand the moving parts and can work on them, but I didn’t create everything ground-up.

In interviews, when I explain this honestly, I can almost feel the interviewer’s interest drop the moment I say “I haven’t personally set up the cluster or administer it” or “I wasn’t responsible for the initial infra design.”

Yet, I see people who exaggerate their contributions land those same roles. People who, frankly, can’t even write solid production-ready manifests or pipelines. There are people who write manifests in Notepad++ who are hired in Lead DevOps role(same as me). It's frustrating working with these people.



So, here’s my question:

* Is it time I start “selling” myself more aggressively in interviews?
* Or is there a way to frame my experience truthfully without underselling what I actually know and can do?



I don’t want to lie, but I’m starting to feel that being 100% transparent is working against me. Has anyone else faced this? How do you balance credibility and confidence in technical interviews; especially in senior DevOps/SRE roles?

I don't like the feeling of getting rejected in final round of interviews. Or am I just overestimating my skills/capabilities and I'm far behind market/job expectations. What is it that I'm doing wrong?

Fresher DevOps Engineer (3 months in) — how can I best use my free time to upskill for a better WLB + higher paying role later?

Hey folks 👋

I joined 3 months ago as a Junior DevOps Engineer (fresher). My CTC is 3 LPA and there’s a 2-year bond (₹1L if I break it). The work is super light, so I get a lot of free time in office.

Here’s what I have access to:

Ubuntu VM with sudo access

ChatGPT

2 weekly offs (Sat & Sun)

Right now I know a bit of Linux, Jenkins, GitLab, SVN, and WinSCP.
My goal is to upskill in DevOps + Cloud, build hands-on projects, and later move to a remote or Hyderabad-based role with better pay + WLB.

My goal:
👉 Build solid DevOps + Cloud skills
👉 Create hands-on projects I can show later on GitHub
👉 Prepare for a better-paying role after my bond (ideally remote or Hyderabad-based)
👉 Maintain a good work-life balance

Can you suggest:

What should I focus on learning next (AWS, Docker, Kubernetes, Terraform, etc.)?

Any project ideas I can do on my Ubuntu VM?

Free resources, YouTube channels, or courses worth following?

How to plan a practical roadmap using ChatGPT + self-practice?

Stuck between a great PhD offer and a solid DevOps career any advice?

I’m currently working as a DevOps Engineer with a good salary, and I’m 27 years old.
Recently, I received an offer to pursue a PhD at a top 100 university in the world. The topic aligns perfectly with my passion — information security, WebAssembly, Rust, and cloud computing.

The salary is much lower than my current salary, and it will take around 5 years to finish the program, but I see this as a rare opportunity at my age to gain strong research experience and deepen my technical skills.

I’m struggling to decide is this truly a strong opportunity worth taking, or should I stay in the industry and keep building my professional experience?
Has anyone here gone through a similar situation? How did it impact your career afterward whether you stayed in academia or returned to industry?


After having a phd in information security, what are the opportunities to come back to the industry?
