Explain the common technical complexities and patterns in integration development18% of the exam
Cloud, hybrid and on-premises deployment architectures
How cloud, hybrid and on-premises architectures differ in where management and runtimes run, who supplies and patches the infrastructure, and where data stays, and why hybrid is the usual middle ground.
Describe the differences between cloud, hybrid, and on-premise deployment architectures.
~6 min read · 3 practice questions ·
What the exam expects
- Classify a deployment as cloud, hybrid or on-premises from where its management layer and its runtimes run.
- Compare the three on control, data location, infrastructure effort and who applies security updates.
- Explain why hybrid integration suits companies that keep legacy systems and sensitive data inside the firewall while adopting SaaS.
- Recognize when regulation rules out every cloud component, including the management console.
Key terms:
- Control plane: the management layer where you design, deploy and manage APIs and apps.
- Runtime plane: where the apps actually run, including the Mule runtime engine.
- Cloud (MuleSoft-hosted): MuleSoft supplies and runs the servers.
- Hybrid: a cloud management console runs apps on the customer's own servers.
- Fully on-premises: management and runtimes both sit in the customer's environment.
Key facts
Planes are independent
- Detail
- Control plane location, runtime option and runtime region are separate choices
CloudHub hosting
- Detail
- No hosting environment to configure; resources set by contract
Hybrid setup
- Detail
- Register servers with the Runtime Manager agent, then deploy
Hybrid data to cloud
- Detail
- Only agent metadata by default; no application data
Hybrid patching
- Detail
- Runtime security updates applied manually
PCE purpose
- Detail
- Strict regulatory or compliance limits on cloud use
PCE connectivity
- Detail
- No external interactions or internet connectivity required
Standalone on-premises runtime
- Detail
- No control plane connection; suits air-gapped sites
- Why might a team planning PCE need another messaging option?
- When you move from CloudHub to hybrid, who applies runtime security updates?
- How often does CloudHub update Mule for a running app?
- Which Kubernetes platforms does PCE 4.x run on?
The questions are free to read. Answers with their sources and self-grading are included with the pack.
