مخرجات التعلم

  1. Distinguish IaaS, PaaS, SaaS, and managed services by what the customer still operates.
  2. Apply the shared-responsibility model to security and operations for each model.
  3. Choose a service model per component based on control, operational burden, cost, and lock-in.

Lab

ARC-011-LAB1 · Service-model matrix

Outcomes: 1–3 · Time: ~2.5 h

  1. List every Larkspur component (storefront, order service, search, payments, databases, media, email, identity, monitoring, ERP adapter, reporting).
  2. Choose IaaS, PaaS, SaaS, or managed service for each, with a one-line reason.
  3. Fill a "who operates what" table: provider, Larkspur team, vendor, per concern (patching, scaling, backup, security, incident response).
  4. Add lock-in kind and exit consideration for each choice.
  5. Highlight responsibility gaps and assign an owner to each.

Acceptance: responsibility gaps identified and assigned.

Exercises (case-based; six exercises)

IDOutcomeTask
ARC-011-EX011Larkspur proposes running its own database on VMs. List what its team would operate that a managed database removes.
ARC-011-EX021Classify five tools Larkspur uses (CRM, payment gateway, container platform, VM, managed queue) as IaaS, PaaS, SaaS, or managed service.
ARC-011-EX032For the SaaS CRM, write the shared-responsibility split for identity, data, availability, and incident response.
ARC-011-EX042A bucket of product invoices was exposed by a configuration error. Whose responsibility is that, and which controls prevent it?
ARC-011-EX053The platform lead wants "full control" with VMs for all services. Write a short note recommending a service model for the order service.
ARC-011-EX063Write an exit assessment for the managed search service: lock-in kind, exit effort, mitigation.
أظهر الحلول
  • EX01 OS and engine patching, backup jobs and restore tests, failover setup, replication, disk growth, monitoring agents; they would still own schema, access, and tuning.
  • EX02 CRM: SaaS; payment gateway: SaaS; container platform: PaaS (or managed service); VM: IaaS; managed queue: managed service.
  • EX03 Vendor: platform availability, infrastructure security. Larkspur: user accounts, SSO, roles, data classification and export rights, deciding the response to a data issue. Incident response is shared with a defined contact path.
  • EX04 Customer side: configuration is always the customer's. Controls: block public access by default, policy guardrails, access reviews, detective checks for public buckets.
  • EX05 Recommend managed containers or PaaS: the team is small, workload is standard, no OS-level need. Control gained from VMs is unused; operating burden and patch risk grow. State when VMs would be justified.
  • EX06 Lock-in: query API and index format. Exit: re-index from the source database in weeks. Mitigation: source of truth stays in the relational store; abstract search behind an internal interface only where cheap.

  1. 1Larkspur rents virtual machines and installs its own runtime. Which model is this?O1
  2. 2A team deploys a container image and the provider patches the OS and runtime. This is closest to:O1
  3. 3With a managed database, which task is still the customer's?O1
  4. 4In every service model, who always owns the data and its access settings?O2
  5. 5An exposed storage bucket caused by a misconfiguration is usually:O2
  6. 6Moving up from IaaS to SaaS, the customer's operational duties generally:O2
  7. 7A small team with a standard web workload should default to:O3
  8. 8Which is a hidden cost of IaaS by default?O3
  9. 9The most honest way to treat lock-in is to:O3
  10. 10"Managed means no operations" is wrong because:O3

الجزء العملي

Matrix review of the ARC-011-LAB1 service-model matrix plus exercises ARC-011-EX01 to EX06. Pass: quiz at least 8/10, at least five of six exercises correct, and every responsibility gap in the matrix assigned to an owner.

أخطاء شائعة

IaaS by default; assuming managed means "no operations".
