Beyond the lessons

Assess, practise, pass the proof

Reading a lesson confirms nothing. A skill is confirmed by a passed quiz, practised in a guided lab, and put to the test by a challenge or a mission; an imported lab result is not verified by the site.

Assess yourself

4 quizzes

At the end of the lessons: passed at 70%, they confirm the skill.

Proof

1 practical proof

• Challenge 1: an architecture on a tight budget

A practical proof is a challenge, a capstone or a declared lab.

Going further

• Régions et zones de disponibilité cloud : comprendre et choisir (in French)

Reference pages: they support the skill without teaching it, and do not count in your journey.

Prepare the environment

• Feint: learn, develop and test the cloud without a cloud account
• Installing Feint: verified release, Homebrew, mise or container
• Wiring the official Scaleway, Outscale and Exoscale CLIs

To do before the labs: these pages do not teach the skill, they set up what you need to practice it.

Same block · Design a cloud environment without depending on the provider

• Choose a workload's service and deployment model and split responsibilities
• Design a cloud environment's private network: addressing, a regional network attached in several zones, routing and default-deny filtering
• Choose a workload's compute model and size it from measurements
• Choose a workload's storage family and class from access, measured performance, durability and cost
• Choose a data service, managed or self-managed, and connect it privately, replication and failover included
• Choose the interconnection and network pattern of a hybrid environment: VPN, dedicated link, BGP, DMZ and hub-spoke
