numberOfBrokers: 1, // 3 whole brokers (1 per AZ)
instanceType: 'specific.m7g.massive',};export const deploymentConfig: DeploymentConfig = { companies: [ { topics: 2, partitionsPerTopic: 6, instances: 3, messageSizeBytes: 1024 }, ]};

Step 2: Redeploy with vertical scaling

// Redeploy: Check vertical scaling impression
export const mskBrokerConfig: MskBrokerConfig = {
numberOfBrokers: 1, // Identical dealer rely
instanceType: 'specific.m7g.xlarge', // Bigger cases
};

// Maintain identical workload configuration to check outcomes

Step 3: Redeploy with horizontal scaling

// Redeploy: Check horizontal scaling impression
export const mskBrokerConfig: MskBrokerConfig = {
numberOfBrokers: 2, // 6 whole brokers (2 per AZ)
instanceType: 'specific.m7g.massive', // Again to authentic measurement
};

// Maintain identical workload configuration to check outcomes
