What Does a Cloud Engineer Do Daily?

AK Ankit Kaushik · Lead Trainer, Data Engineering & AI | Updated 7 November 2026 | 16 min read Free · Career Guide

A cloud engineer monitors systems, provisions infrastructure as code, secures accounts and optimises cost.

Quick summary — what does a cloud engineer do

What does a cloud engineer do? They design, build, monitor and secure the cloud infrastructure apps run on. A typical day includes checking alerts and dashboards, provisioning resources with code such as Terraform, reviewing access and security settings, helping developers deploy, fixing incidents and keeping costs under control. Linux, networking, one cloud platform and scripting are core skills.

In this guide you will learn:

A typical day — what a cloud engineer does hour by hour.
Core responsibilities — monitoring, provisioning, security and cost.
Tools and skills — what you need to learn.
Work templates — runbooks and checklists used on the job.
Getting started — how freshers can enter the role.

SECTION 01A typical day in the life of a cloud engineer

No two days are identical, but most follow a pattern: start by checking system health, spend the middle of the day building or improving infrastructure, and finish with reviews and documentation. Incidents can interrupt any part of the day.

Time	Activity	Example task	Skill used
Morning	Health check and alerts	Review overnight alarms and dashboards	Monitoring, troubleshooting
Late morning	Team stand-up and tickets	Plan a new database for a feature	Communication, planning
Afternoon	Build and automate	Write Terraform for a new environment	Infrastructure as Code
Evening	Review and document	Update a runbook; review a cost report	Documentation, cost awareness

# Quick morning health checks with the AWS CLI
aws cloudwatch describe-alarms --state-value ALARM \
    --query "MetricAlarms[].AlarmName"
aws ec2 describe-instance-status \
    --filters Name=instance-status.status,Values=impaired
aws ce get-cost-and-usage \
    --time-period Start=2026-11-01,End=2026-11-07 \
    --granularity DAILY --metrics UnblendedCost

Daily stand-up (2 minutes each)
Yesterday: Finished staging VPC in Terraform; fixed disk alarm
Today:     Add RDS module; review IAM request from dev team
Blockers:  Waiting for approval on production change window

morning-checks.sh

Key insight: Much of a cloud engineer's value is preventing problems — good monitoring means fewer late-night emergencies.

SECTION 02Core responsibilities explained

Cloud engineering roles vary by company, but four responsibilities appear in almost every job description. Understanding them helps you focus your learning on what teams actually need.

Responsibility	What it means	Typical tools	Example
Provisioning	Creating servers, networks, databases	Terraform, CloudFormation	Spin up a test environment
Monitoring & incidents	Watching health, fixing outages	CloudWatch, Prometheus, Grafana	Respond to a high-CPU alert
Security & access	Protecting accounts and data	IAM, KMS, security groups	Grant least-privilege access
Cost optimisation	Avoiding waste	Cost Explorer, budgets, tagging	Shut down idle instances

# Alarm when average CPU > 80% for 10 minutes
aws cloudwatch put-metric-alarm \
  --alarm-name web-high-cpu \
  --namespace AWS/EC2 --metric-name CPUUtilization \
  --dimensions Name=InstanceId,Value=i-0123456789abcdef0 \
  --statistic Average --period 300 --evaluation-periods 2 \
  --threshold 80 --comparison-operator GreaterThanThreshold \
  --alarm-actions arn:aws:sns:ap-south-1:123456789012:ops-alerts

# A tagged EC2 instance - tags help track cost by team
resource "aws_instance" "web" {
  ami           = var.ami_id
  instance_type = "t3.micro"
  subnet_id     = var.subnet_id

  tags = {
    Name        = "web-staging"
    Team        = "payments"
    Environment = "staging"
  }
}

cpu-alarm.sh

Tip: Tag every resource with owner, team and environment. Tags make cost reports and clean-ups far easier.

SECTION 03Tools and skills a cloud engineer needs

The job blends system administration, networking, automation and communication. You do not need everything on day one, but this is the skill set teams look for in junior cloud engineers.

Skill area	What to learn	Why it matters	How to practise
Linux	Shell, processes, logs, permissions	Most cloud servers run Linux	Run a Linux VM daily
Networking	IP, subnets, DNS, load balancers	Most outages involve networking	Build a VPC from scratch
One cloud deeply	AWS or Azure core services	Depth beats breadth early	Hands-on labs + a certification
Automation	Terraform, Python or Bash scripts	Repeatable, reviewable changes	Rebuild your lab entirely from code

# List running EC2 instances missing a 'Team' tag (pip install boto3)
import boto3

ec2 = boto3.client("ec2", region_name="ap-south-1")
pages = ec2.get_paginator("describe_instances").paginate(
    Filters=[{"Name": "instance-state-name", "Values": ["running"]}])

for page in pages:
    for res in page["Reservations"]:
        for inst in res["Instances"]:
            tags = {t["Key"]: t["Value"] for t in inst.get("Tags", [])}
            if "Team" not in tags:
                print(inst["InstanceId"], "missing Team tag")

Junior cloud engineer readiness
[ ] Linux commands and log reading
[ ] Subnets, routing, security groups
[ ] EC2, S3, IAM, VPC, RDS hands-on
[ ] Terraform: plan, apply, modules, state
[ ] One scripting language (Python or Bash)
[ ] Monitoring and alarms
[ ] Clear written runbooks

untagged_instances.py

Key insight: Clear communication is a core skill. Cloud engineers explain risks, write runbooks and work with many teams every day.

SECTION 04Work templates cloud engineers use

These templates mirror real documents from cloud teams. Practise filling them during your learning projects.

Runbook: High CPU on web servers
Trigger: Alarm 'web-high-cpu' in ALARM state
1. Check CloudWatch: is it one instance or all?
2. If one: check app logs, restart service if hung
3. If all: check traffic spike in load balancer metrics
4. Scale out: increase Auto Scaling desired capacity
5. Note findings in the incident channel
6. After recovery: open a ticket for root-cause review

Change request
Title: Add read replica to orders database
Reason: Reporting queries slowing the main database
Plan: Terraform change, reviewed in pull request
Risk: Low; no downtime expected
Rollback: Remove replica via Terraform
Window: Thursday 22:00 IST
Approver: Team lead

Weekly cost review
[ ] Compare spend with last week (Cost Explorer)
[ ] Idle or stopped instances with attached volumes?
[ ] Unattached EBS volumes and old snapshots?
[ ] Oversized instances (low CPU for weeks)?
[ ] Untagged resources - find owners

SECTION 05Tips to become a cloud engineer

How freshers and career-switchers can move into the role:

Start with Linux and networking — these two areas come up in nearly every cloud interview.
Go deep on one platform — AWS or Azure; master core services before adding a second cloud.
Build everything as code — a GitHub repo of Terraform projects shows real-world habits.
Practise troubleshooting — break your lab on purpose and fix it, then write a runbook.
Consider support or operations roles first — they are common entry points into cloud engineering.

Pro tip: In interviews, describe one incident you solved in your lab — what broke, how you found it and how you prevented it. It shows the exact thinking teams need.

SECTION 06Interview Q&A — Cloud engineer role

Q1What is the difference between a cloud engineer and a DevOps engineer?

Cloud engineers focus on designing and running cloud infrastructure. DevOps engineers focus on delivery pipelines and collaboration practices. The roles overlap a lot in many companies.

Q2What is Infrastructure as Code?

Managing infrastructure through code files, using tools like Terraform, so changes are versioned, reviewed and repeatable.

Q3What is auto scaling?

Automatically adding or removing compute capacity based on demand, so applications stay responsive while avoiding paying for idle servers.

Q4How do you troubleshoot an unreachable EC2 instance?

Check instance status checks, security group and network ACL rules, route tables, the instance's public IP or load balancer, and the service and logs on the instance.

Q5What is a runbook?

A documented set of steps for handling a specific situation, such as an alert, so anyone on the team can respond consistently.
