du -sh /var/log/*                # Size of each directory in /var/log

The goal is not to memorize commands. It is to be comfortable troubleshooting a Linux server when something breaks — because in cloud engineering, something always breaks, and the first thing you do is SSH into the instance and check logs.

Networking Fundamentals (4 weeks):

Cloud networking is TCP/IP networking with a different interface. These concepts map directly to AWS/Azure/GCP:

Build a home lab: set up two VMs on the same virtual network. Configure static IPs, set up a DNS server (dnsmasq), configure iptables firewall rules, and set up Nginx as a reverse proxy. This exercise teaches you what a VPC does before you ever log into AWS.

Handling Internet Connectivity Challenges

I know the reality. Power goes out. Internet drops. MTN throttles at peak hours. Airtel is faster in some areas, slower in others. This is not a blocker — it is a constraint you plan around.

Practical solutions that work in 2026:

• Starlink: Available in Nigeria, Kenya, and South Africa as of 2025. $50/month residential plan provides 50-200 Mbps. If you can afford it, this eliminates connectivity as a bottleneck.
• Dual ISP: Use two different ISPs (e.g., Spectranet + MTN in Lagos, Safaricom + Zuku in Nairobi). Configure your router for automatic failover. Cost: $40-80/month total.
• Generator or solar + battery: For areas with unreliable power. A 1 KVA inverter with battery backup costs 200K-400K NGN and provides 4-6 hours of backup for a laptop and router.
• Co-working spaces: Lagos (CcHub, Andela Learning Community spaces), Nairobi (iHub, Nailab), Accra (Impact Hub). Reliable power and internet, $50-150/month.
• Offline study: Download AWS documentation as PDFs (docs.aws.amazon.com has a "Download PDF" button on every service guide). Download video courses for offline viewing. Study AWS whitepapers offline. Practice CLI commands on a local Linux VM.

AWS Free Tier and Cost Management:

AWS Free Tier gives you 12 months of limited access to 85+ services. Specific limits that matter for learning:

EC2: 750 hours/month of t2.micro or t3.micro (Linux)
S3: 5 GB storage, 20,000 GET requests, 2,000 PUT requests
RDS: 750 hours/month of db.t2.micro or db.t3.micro
Lambda: 1 million requests/month, 400,000 GB-seconds
DynamoDB: 25 GB storage, 25 read/write capacity units
CloudWatch: 10 custom metrics, 10 alarms, 1 million API requests

Set a billing alarm immediately after creating your account:

aws cloudwatch put-metric-alarm \
  --alarm-name "BillingAlarm-10USD" \
  --metric-name EstimatedCharges \
  --namespace AWS/Billing \
  --statistic Maximum \
  --period 21600 \
  --threshold 10 \
  --comparison-operator GreaterThanThreshold \
  --dimensions Name=Currency,Value=USD \
  --evaluation-periods 1 \
  --alarm-actions arn:aws:sns:us-east-1:ACCOUNT_ID:billing-alerts

I have seen students in Lagos receive $200 AWS bills because they left an RDS Multi-AZ instance running for a month. Set the alarm. Check the billing dashboard weekly.

Phase 2: Cloud Platform Mastery (Months 4-6)

Pick One Cloud First

Do not try to learn AWS, Azure, and GCP simultaneously. Pick one, get certified, get hired, then expand. Here is how to choose:

• AWS if you want the most job opportunities globally. AWS has 32% of the global cloud market and dominates African enterprise deployments. The SAA-C04 certification is the most recognized credential in cloud engineering.
• Azure if you work in or target enterprises that use Microsoft products (Active Directory, Office 365, SQL Server). Many African government agencies and financial institutions use Azure.
• GCP if you are interested in data engineering, machine learning, or Kubernetes. Google's BigQuery and Vertex AI are industry-leading.

For most African engineers, I recommend starting with AWS. The job market is largest, the documentation is deepest, and the certification is most recognized.

AWS Certification Path for African Engineers

Month 4-6: AWS Solutions Architect Associate (SAA-C04)
  → Exam cost: $150 USD (~230,000 NGN, ~19,500 KES, ~2,700 ZAR)
  → Study: 10-12 hours/week for 8 weeks
  → Pass rate (with structured study): 78%

Month 7-9: AWS Developer Associate or SysOps Administrator
  → Choose Developer if you write application code
  → Choose SysOps if you manage infrastructure
  → Exam cost: $150 USD each

Month 10-12: Terraform Associate (HashiCorp)
  → Exam cost: $70 USD
  → Cross-cloud skill, highly valued
  → Study: 4-6 weeks at 8 hours/week

The certification exam costs are significant in local currency. Strategies to reduce cost:

• AWS re/Start program: Free 12-week cloud training program with exam voucher. Available in South Africa and expanding to other African countries.
• AWS Community Builder program: Apply at aws.amazon.com/developer/community/community-builders. Accepted members receive exam vouchers and credits.
• AWS User Groups: Lagos AWS User Group, Nairobi AWS User Group, Accra AWS User Group. Active communities that sometimes distribute exam vouchers at events.
• Employer sponsorship: Many employers will pay for certification exams if you pass. Negotiate this during hiring.

Building a Portfolio That Gets Interviews

Certifications open doors. Portfolios close deals. Here is what hiring managers actually look at:

Project 1: Deployed Web Application (Week 1-2) Deploy a three-tier web application on AWS. VPC with public/private subnets, EC2 instances behind an ALB, RDS PostgreSQL database, S3 for static assets, CloudFront for CDN. Document the architecture with a diagram. Write a blog post explaining each decision. Push the infrastructure code (Terraform or CloudFormation) to GitHub.

Project 2: Serverless API (Week 3-4) Build a REST API using API Gateway + Lambda + DynamoDB. Add Cognito authentication. Implement CRUD operations. Deploy with SAM or CDK. Write automated tests. Document the API with OpenAPI/Swagger. This demonstrates serverless skills, which are increasingly demanded.

Project 3: CI/CD Pipeline (Week 5-6) Set up a complete CI/CD pipeline using GitHub Actions. On push to main: run tests, build Docker image, push to ECR, deploy to ECS Fargate. Include infrastructure provisioning with Terraform. This single project demonstrates containers, CI/CD, IaC, and AWS services.

Project 4: Monitoring and Alerting (Week 7-8) Instrument one of your applications with CloudWatch metrics, alarms, and dashboards. Set up SNS notifications for critical alerts. Create a CloudWatch Log Insights query that extracts error rates. Add X-Ray tracing to your Lambda functions. This demonstrates operational maturity that distinguishes you from other candidates.

Put all four projects on GitHub with clear README files, architecture diagrams, and deployment instructions. Link them from your LinkedIn profile.

Phase 3: Getting Hired (Months 7-12)

Remote Job Platforms That Hire from Africa

These platforms actively source cloud engineering talent from Africa:

The Interview Loop for Cloud Engineering Roles

Cloud engineering interviews in 2026 typically follow this structure:

Round 1: Technical Screen (45-60 min) - AWS/Azure/GCP service knowledge (scenario-based questions) - Linux troubleshooting (live terminal or described scenarios) - Networking questions (VPC design, DNS resolution, TLS) - Terraform/CloudFormation questions (state management, module design)

Round 2: System Design (60 min) - Design a multi-region, highly available architecture for a specific use case - Discuss tradeoffs: cost vs performance vs reliability - Draw architecture diagrams (use draw.io or Excalidraw) - Estimate costs using AWS Pricing Calculator

Round 3: Hands-On/Coding (60-90 min) - Write Terraform to deploy a specific architecture - Debug a failing CloudFormation template - Write a Python/Bash script to automate an AWS task - Troubleshoot a broken application on EC2/ECS

Round 4: Behavioral (45 min) - Incident response stories (describe a production incident and how you resolved it) - Collaboration and communication - How you handle ambiguity and make decisions under pressure

Prepare for these by practicing. Do mock system design sessions with other engineers. Write Terraform under time pressure. Practice explaining complex architectures clearly — this is especially important for remote roles where written communication is your primary medium.

Building Your Network from Africa

The cloud engineering community is one of the most accessible tech communities for African engineers. Here is where to start:

• AWS User Groups: Lagos, Nairobi, Accra, Johannesburg, Cairo all have active groups with monthly meetups. Attend consistently. Present a talk after 3-4 months of attending.
• HashiCorp User Groups: Several African cities have Terraform user groups.
• Cloud Native Computing Foundation (CNCF): KubeDay Africa and KubeCon have African-focused programming.
• Twitter/X: Follow AWS Heroes from Africa. Engage with their content. Share your own learning journey.
• Dev.to and Hashnode: Write about what you learn. "How I set up VPC peering in AWS" gets read by hiring managers who search for talent on technical blogs.
• Open Source Contributions: Contribute to Terraform providers, AWS CDK constructs, or Kubernetes operators. Even documentation PRs demonstrate competence and collaboration.

Navigating Time Zones

Africa sits between US and Asia time zones, which is an advantage for remote work:

WAT (Nigeria, Ghana): UTC+1
  → US East Coast overlap: 2 PM - 6 PM WAT (9 AM - 1 PM EST)
  → US West Coast overlap: 5 PM - 9 PM WAT (9 AM - 1 PM PST)
  → Europe overlap: 9 AM - 6 PM WAT (full business day)

EAT (Kenya, Ethiopia): UTC+3
  → US East Coast overlap: 4 PM - 8 PM EAT (9 AM - 1 PM EST)
  → Europe overlap: 10 AM - 7 PM EAT (full business day)

SAST (South Africa): UTC+2
  → US East Coast overlap: 3 PM - 7 PM SAST (9 AM - 1 PM EST)
  → Europe overlap: 9 AM - 6 PM SAST (full business day)

European companies offer the best time zone alignment for African engineers. US companies typically expect 3-4 hours of overlap with US business hours, which is feasible but means late afternoons or early evenings.

Phase 4: Leveling Up (Year 2 and Beyond)

Once you have your first cloud engineering role, your growth trajectory depends on specialization:

Path A: Cloud Architecture — Design enterprise-scale systems. Get AWS Solutions Architect Professional. Learn Well-Architected Framework deeply. Target: $150K-$220K remote.

Path B: DevOps/SRE — Build CI/CD pipelines, monitoring systems, incident response. Get CKA (Certified Kubernetes Administrator) and Terraform Associate. Target: $130K-$180K remote.

Path C: Cloud Security — Specialize in IAM, network security, compliance frameworks (SOC 2, HIPAA, PCI DSS). Get AWS Security Specialty and CCSP. Target: $140K-$200K remote.

Path D: Data Engineering — Build data pipelines on cloud platforms. Learn Spark, Airflow, dbt, and cloud-native data services (Glue, Dataflow, Synapse). Target: $130K-$190K remote.

Each path has strong demand in 2026, and all four paths are accessible from Africa with remote work.
