.NET Shop, Tools for Performance Analysis

Hello everyone,

I'm fairly new to performance in general, but I see tons of resources on performance analyzing via perf tools in linux like from Brendan Gregg.

In a dotnet shop, how would I go utilizing tools that are equivalent to this for gathering performance related data that can help me debug performance bottlenecks?

I was thinking either gaining access to the actual server and running CLI commands that .NET already has or running a container in linux that has the APIs hosted there, but I assume that wouldn't be accurate performance analysis due to the varying environment differences.

I've been learning how to utilize perfview/WPA and just using the stack trace that is gathered on Application Insight.

Some tools we use for monitoring/logging are:

\- Azure/Application Insight

\- Splunk

I'm quite lost on which direction to go, but if anyone can help. Thank you!

How are SaaS Companies typically hosted

Hey,


I currently host my SaaS as an Azure App service for the backend and Azure Static Web Apps for the frontend, if anyone else here is on Azure, how do you host your frontend & backend? The issue is switching to NextJS so site will no longer be static and will require SSR with the frontend.

Best,


NoWeakness

Where to go after DevOps?

I have been in technology long enough to have experienced the early days of the traditional sysadmins with in house servers, networking, then DevOps, SRE and most recently platform engineering, understanding they are not exactly the same thing. This path brought me a lot of knowledge and professional satisfaction to a certain degree, however, I think I am in a pivotal point where i don't know what makes sense for me to be the next step.

I would like to capture some impressions from people who had transit a similar path, what was next for you?

Deploying uWSGI without NGINX (or webservers)

I am currently designing a deployment for a financial app managing 100k pay points.

Options are below
haproxy (load balancer) => nginx/uwsgi/django
or
nginx (load balancer) => uwsgi/django
or
haproxy (load balancer) => uwsgi/django

To reduce latency, I am leaning towards the last option which is removing NGINX and making uWSGI to ask as the reverse proxy as well as the wsgi.

What are the cons, or issues with the option?

How much should I ask for to move be on-call?

Hope this isn't too much of a 'career' question for this sub, let me know and I'l delete:

I'm working on salary at a small shop, just me and one SRE on incident response, and to close a large new client they're asking that we have an on-call policy. Previously it was pretty casual, now I'm being asked to cover half the calendar. We generally have less than one incident per week, but there were queueing issues late last year where there were incidents every day.

My manager, who is great, asked me to pick a number for compensation for on-call and I really don't know what to ask for. I like this job so I'm not going to quit or threaten to quit over this, just want some advice.

US salaried employee, making industry median if that's helpful.

Mac in cloud replacement

Hi everyone, we are currently using mac in cloud services in order to run a dedicated mac server, as we have crucial software that is available only on IOS.

We have multiple users login via VNC in order to work simultaneously, and currently we are experiencing some issues with mac in cloud.

I am looking for a new mac server cloud provider, and looking for recommendations.

I saw macstadium and macweb, anyone have any previous experience with them?

GitOps - how to generate manifests in CI step and apply in CD step?

I'm learning CICD with ArgoCD and Argo Workflows, and I want to set up a system for devs where they can deploy new apps just by providing a link to a repository.

The workflow I have in mind is:

1. Build an image for the code and push it to a registry
2. Generate manifest files for a new deployment
3. Push the files to the ArgoCD repository.
4. Let ArgoCD reconcile the manifests and deploy the app.

What I'm not sure about is how to proceed with steps 2 and 3. I've searched a lot and found many examples for updating an image tag in an existing manifest with things like ArgoCD image updater, but nothing about adding new manifests

What would be the best way to do this? Am I supposed to have the workflow commit the manifests to git? Something like this?

- name: Prepare Kubernetes manifests
run: |
# Example: Dynamically creating a Helm values file if it doesn't exist
if ! -f "chart/${{ matrix.app }}/values.yaml" ; then
echo "image: myregistry/${{ matrix.app }}:${{ github.sha }}" > chart/${{ matrix.app }}/values.yaml
fi


- name: Commit and push changes
run: |
git config user.name 'GitHub Actions'
git config user.email '[email protected]'
git add .
git commit -m "Deploying new version of ${{ matrix.app }} - ${{ github.sha }}"
git push

DevOps School Encourages To Fake Experience

Hello, there is a DevOps school in Chicagoland that encourages the students to fake their experience I mean they literally tell you to pick a company and add 5-8 years of fake experience. They have a fake staffing company with the backup numbers in case when the companies are trying to verify the experience. Are there any ways to stop this nonsense?
Don't get me wrong but it creates a lot of unfair condition to the people who just starting in devops or don't want to fake on their resumes.

Which Cloud provider offer free credits on GPU Nvidia instances?

I want to test and train my AI model on GPU VM but when trying Azure or Google Cloud, they doesnt allow to use free credits on GPU instances (at least those in which I'm interested in). Is there any provider I could use or I will need to pay for this kind of machines from my wallet?

How to practice CI/CD?

Hello, I am new to devops. I have been watching some video on Youtube on how to get starterd (mostly videos on Gitlab). So far I watched TechWorld with Nana 1 hour video and Automation Step by Step playlist on Gitlab. My question is how should I practice CI/CD. And any other resources preferrably free.

Where do I draw the line between Mid- and Senior-level effort, so that I don't do more work than I'm being paid for?

I recently applied to a senior level role at a company. They ended up making me an offer but at a lower salary than I was expecting (It's a pay cut but it's not exactly crap pay either). I also noticed that my title in HR System does not include senior.

I'm the only full-time infra engineer.

I'm totally capable of going into the company and leading all efforts for their current and future needs, but they're not titling nor paying me to do so apparently.

I've been trying to read through generalized engineering levels on the internet, but most are written about software developers.

So, I'm asking here, too:

How much effort and responsibility would you limit yourself to? and what boundaries would you hold? in order to make sure you weren't doing senior level work for mid pay and title. Thanks!

Should I monitor my monitoring stack?

(🤯)
How do you ensure that your monitoring stack is working as expected and you didn't messed up the config?

If you're using a Saas (Grafana cloud, datadog, whatever) do you have another solution that will alert you in case of an outage?

Maybe it's just that there's no simple solution that's worth the effort. ¯\\_(ツ)_/¯
