@twtayaan Thanks bro I actually used it.

@PJrArthur1 Glad it helped 🙌

Prometheus Architecture Explained: 🔍 Step 1 → Retrieval & Service Discovery: Automatically discovers targets in dynamic environments like K8s to pull metrics. Step 2 → Prometheus Server: The central engine that scrapes data, handles logic, and manages the storage lifecycle. Step 3 → TSDB: An efficient time-series database that stores metrics for fast real-time and historical querying. Step 4 → Pushgateway: A specialized component that captures metrics from short-lived jobs before they exit. Step 5 → Exporters: Translators that expose metrics from third-party apps and systems for Prometheus to ingest. Step 6 → Alertmanager: The watchdog that triggers notifications to Slack or Email based on your defined thresholds. Step 7 → PromQL & Grafana: Use advanced queries to feed data into the Prometheus UI or build custom dashboards in Grafana. Prometheus is the gold standard for full-stack observability in distributed, cloud-native systems. Source Repo: github.com/iam-veeramalla…

@QuietFSoftware Why do you need an app?

Any good calisthenic workout app recommendations? Most of the ones I see all really need a subscription 😑

Reminder for anyone learning DevOps: You don't have to know everything. Linux, Docker, Kubernetes, Terraform, AWS, GCP, CI/CD, service mesh, eBPF, GitOps, SRE, observability... Nobody knows all of it. Not even the people who tweet as experts. Pick a direction. Go deep. The breadth comes naturally over time. What's the one area you're going deep on right now?

@fromcodetocloud Thanks 🙏

@PJrArthur1 well done

Finally, I got to understand storing a terraform state file in an S3 bucket coupled with dynamodb state locking.

Right now I am also on monitoring and observability more specifically with Prometheus and Grafana. Update incoming....

This was a simple terraform project to understand variables, modules and .tfvars.

@devops_nk Yeah I did not recall it correctly. I just took a look at my projects and realized it. Thanks!

@PJrArthur1 Let me tell you: test is terraform resource name test-lb-tf will be created in aws

Which name is going to be created in AWS out of these two? This question asked to me in last DevOps interview.

@brankopetric00 This has been true for me.

claude opus is fairly dumb these days

I even deleted Nano just to get rid of the reflex use it and create a new reflex for Vim😁.

@livingdevops Yeah! I missed that part

@PJrArthur1 Yet people do it, specially when people use cicd for terraform

When you accidentally run terraform destroy - - auto-approve On prod environments instead of training env And realise the mistakes after 5 min

@__karnati I most often open a text editor for this.

🔧 Linux bit: echo 'hello' > file.txt ← overwrites the file echo 'hello' >> file.txt ← appends to the file One extra > is the difference between adding a log line and deleting your entire log. Slow down before you type that redirect. Always.

@devops_nk Jenkins so far!

Jenkins or GitHub Actions Which one you are using in your project ?

@devops_nk Hi

Twitter is cool. But it hits differently when your timeline is full of DevOps Engineers, Software Engineers, SREs, and Cloud Engineers shipping reliable systems. If you're into AWS, Kubernetes, CI/CD, Automation, Site Reliability, or Tech Content Creation say hi 👋

@cloclodma B

Interview question. In AWS, which load balancer offers lower latency and why? A - Application load balancer B- Network load balancer

Decided to create a full EC2 infrastructure with this network and SG setup.
