Focus Track

Cloud & Networking

From fibre and peering to edge and cloud: build fast, secure systems that work for South Africa.

The Internet

Networks linked by undersea cables, terrestrial fibre, peering, and IXPs moving packets between providers.

Domains & Routing

IP addresses, DNS, BGP routing; latency shaped by path choices and distance.

Web Basics

HTTP/HTTPS over TLS for secure delivery; CDNs cache at the edge to reduce latency.

Load & Scale

Load balancers spread traffic; autoscaling and caching keep apps responsive.

South African Reality

AWS launched its Africa (Cape Town) Region in 2020.
Latency matters: Cape Town vs Johannesburg vs overseas routes.
Local ISPs and peering shape student experience on campus networks.
CDNs (Cloudflare, AWS, Google, Microsoft) bring content closer to Africa.
Undersea Cables & IXPs

Africa connects via submarine cables and IXPs; peering reduces hops and latency.

Edge & CDN

Serve static assets and APIs closer to Cape Town/JHB to cut round trips.

Compute Choices

Mix serverless, containers, and VMs; right-size for cost and performance.

Security

TLS everywhere, WAFs, secrets management, network segmentation.

Data & Backup

Replicate data, test restores, and respect residency where required.

Observability

Logs, metrics, traces, and synthetic tests for uptime and latency.

Tools & Practices

  • Docker for packaging; Kubernetes basics for orchestration.
  • Terraform/IaC for repeatable environments.
  • Cloud providers: AWS, Azure, GCP; CDN/edge via Cloudflare.
  • CI/CD: GitHub Actions; automated tests and linting before deploy.
  • Monitoring and logging: metrics, traces, uptime, error budgets.
  • • Design for latency: cache, edge, and regional placement.
