Hands-On: Step-by-Step Tutorial

Let's deploy a simple "Hello, World!" Java application using the IBM Cloud CLI.

Prerequisites:

IBM Cloud account
IBM Cloud CLI installed and configured (https://cloud.ibm.com/docs/cli?topic=cli-install-configure)
Docker installed

Steps:

Create a Java Application:

   public class HelloWorld {
       public static void main(String[] args) {
           System.out.println("Hello, World!");
       }
   }

Compile the code: javac HelloWorld.java

Create a Dockerfile:

   FROM openjdk:17-slim
   COPY HelloWorld.class /app
   WORKDIR /app
   CMD ["java", "HelloWorld"]

Build the Docker Image:

   docker build -t my-hello-world .

Login to IBM Cloud Container Registry:

   ibmcloud cr login

Tag the Docker Image:

   docker tag my-hello-world us-south.cr.cloud.ibm.com/your-namespace/my-hello-world

(Replace your-namespace with your IBM Cloud namespace)

Push the Docker Image:

   docker push us-south.cr.cloud.ibm.com/your-namespace/my-hello-world

Provision "Get Started Java" (using CLI - simplified example):

   ibmcloud resource service-instance-create get-started-java-instance starter -p '{"version":"1.0"}'

(This is a simplified example. The actual command may vary based on your region and configuration.)

Deploy the Application: (This step involves creating Kubernetes deployment and service configurations, which are beyond the scope of this simplified tutorial. Refer to IBM Cloud documentation for detailed instructions.)
Test the Application: Access the deployed application through the exposed endpoint.

Pricing Deep Dive

"Get Started Java" utilizes a pay-as-you-go pricing model. You are charged based on the resources consumed, including:

Compute: Based on the size and number of Kubernetes worker nodes.
Storage: For storing container images and application data.
Network: For data transfer.

Example:

A small development environment with 2 vCPUs and 4GB of RAM might cost around $50-$100 per month. A production environment with higher resource requirements will cost more.

Cost Optimization Tips:

Right-size your resources: Choose the smallest instance size that meets your application's needs.
Auto-scaling: Automatically scale resources up or down based on demand.
Reserved Instances: Consider purchasing reserved instances for long-term workloads.
Monitor resource usage: Identify and eliminate unused resources.

Cautionary Notes:

Network egress charges can be significant. Optimize data transfer to minimize costs.
