Tutorial — Choose Your Hosting Plan¶

This Java tutorial section includes four complete plan tracks. Every track uses the same seven-step learning sequence so you can compare behavior and trade-offs with minimal context switching.

Which Plan Should I Start With?¶

    Start[I am building an Azure Functions Java app] --> Q1{Need scale to zero?}
    Q1 -->|Yes| Q2{Need VNet integration?}
    Q1 -->|No| DEDI[Dedicated ASP]
    Q2 -->|Yes| FLEX[Flex Consumption FC1]
    Q2 -->|No| CONS[Consumption Y1]
    FLEX --> Q3{Need always warm instances?}
    Q3 -->|Yes| PREM[Premium EP]
    Q3 -->|No| FLEX

Plan Comparison at a Glance¶

Feature	Consumption (Y1)	Flex Consumption (FC1)	Premium (EP)	Dedicated (ASP)
Scale to zero	Yes	Yes	No	No
VNet integration	No	Yes	Yes	Yes (tier dependent)
Deployment slots	Limited	No	Yes	Yes
Always warm instances	No	Optional	Yes	Yes
Billing model	Per execution	Per execution	Prewarmed instances	Reserved plan
Recommended Java runtime	17	17	17 or 21	17 or 21

Tutorial Tracks¶

Consumption (Y1)¶

Baseline serverless model with pay-per-execution billing and quick onboarding.

Flex Consumption (FC1)¶

Serverless plus networking and memory controls for modern production workloads.

Premium (EP)¶

Always-ready instances and advanced deployment patterns for low-latency systems.

Dedicated (App Service Plan)¶

Fixed-capacity hosting for teams already operating App Service footprints.

Seven-Step Learning Sequence¶

Step	Focus	Outcome
01	Local Run	Build and execute Java function app locally
02	First Deploy	Provision resources and deploy first release
03	Configuration	Set app settings and JVM options safely
04	Logging and Monitoring	Enable logs, traces, and core alerts
05	Infrastructure as Code	Reproduce platform with Bicep templates
06	CI/CD	Automate build, test, and deployment
07	Extending Triggers	Add queue, blob, timer, and event-driven patterns
