Amazon Elastic Compute Cloud (Amazon EC2) is a web service offered by Amazon Web Services (AWS) that provides resizable compute capacity in the cloud. EC2 allows users to launch and manage virtual machines.

❗️ 𝗗𝗼'𝘀
✔️ 𝗣𝗹𝗮𝗻 𝗔𝗵𝗲𝗮𝗱 📝
Map your requirements and select the right instance type to optimize performance and costs.
✔️ 𝗦𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗙𝗶𝗿𝘀𝘁 🔐
Prioritize security groups, IAM roles, and key pairs to safeguard your EC2 instances.
✔️ 𝗕𝗮𝗰𝗸𝘂𝗽𝘀 𝗠𝗮𝘁𝘁𝗲𝗿 💾
Regularly back up your data to S3 or use automated snapshots for peace of mind.
✔️ 𝗠𝗼𝗻𝗶𝘁𝗼𝗿𝗶𝗻𝗴 & 𝗔𝗹𝗲𝗿𝘁𝘀 📊
Set up CloudWatch for real-time insights into your instances and establish alerts for critical metrics.
✔️ 𝗦𝗰𝗮𝗹𝗶𝗻𝗴 𝗦𝗺𝗮𝗿𝘁𝗹𝘆 ⚖️
Use Auto Scaling to adjust capacity based on demand, saving costs during lulls.

❗️𝗗𝗼𝗻'𝘁𝘀

❤️‍🔥6 Most Confusing GIT Commands 👇

🟡 Simplified and concise illustration of commands for better understanding

𝟭. 𝗴𝗶𝘁 𝗺𝗲𝗿𝗴𝗲 𝘃𝘀 𝗴𝗶𝘁 𝗿𝗲𝗯𝗮𝘀𝗲:
- 𝘨𝘪𝘵 𝘮𝘦𝘳𝘨𝘦 combines branch changes with new merge commits
- 𝘨𝘪𝘵 𝘳𝘦𝘣𝘢𝘴𝘦 moves branch changes on top, creating a linear history

𝟮. 𝗴𝗶𝘁 𝗿𝗲𝘀𝗲𝘁 𝘃𝘀 𝗴𝗶𝘁 𝗿𝗲𝘃𝗲𝗿𝘁:
- 𝘨𝘪𝘵 𝘳𝘦𝘴𝘦𝘵 undoes changes and moves the branch pointer, discarding subsequent commits
- 𝘨𝘪𝘵 𝘳𝘦𝘷𝘦𝘳𝘵 creates new undo commits, preserving history

𝟯. 𝗴𝗶𝘁 𝗳𝗲𝘁𝗰𝗵 𝘃𝘀 𝗴𝗶𝘁 𝗽𝘂𝗹𝗹:
- 𝘨𝘪𝘵 𝘧𝘦𝘵𝘤𝘩 downloads remote changes without auto-merging
- 𝘨𝘪𝘵 𝘱𝘶𝘭𝘭 fetches and auto-merges remote changes

In short,
git pull = git fetch + git merge
–
DevOps is the most happening and integral part of almost all organizations.

🌟 Azure vs AWS vs GCP

Lately, I've been noticing a surge in discussions comparing different cloud services across various providers.🌩🔍

It sparked my curiosity, and I thought, "Why not create my own comparison?" 🤔

So, after diving deep and gathering insights, I've put together my version. 🚀

kubectl get pods --all-namespaces -o jsonpath="{.items[*].spec.containers[*].image}" | sort | uniq -c

➡️ Dive deeper into your Kubernetes clusters with this power command! It lists all container images used by your pods across all namespaces, sorts them, and gives you a count of each unique image. It's a great way to audit and manage your container images and ensure consistency across your deployments.

𝐏𝐫𝐨 𝐓𝐢𝐩: Mastering jsonpath with kubectl can unlock powerful ways to query and manipulate your Kubernetes resources directly from the command line.
