Quick Answer
The answer is AWS Auto Scaling. This service is the correct choice because it dynamically adjusts the number of SAP application server instances based on real-time demand, using scaling policies tied to metrics like CPU utilization or memory, which directly addresses the need to handle sudden user load spikes without manual intervention. On the AWS Certified SAP on AWS Specialty PAS-C01 exam, this question tests your understanding of elastic SAP deployments and the distinction between AWS Auto Scaling and related services like Elastic Load Balancing or EC2 Auto Scaling groups—a common trap is confusing the service that triggers scaling (AWS Auto Scaling) with the underlying compute resource (EC2). Remember, AWS Auto Scaling is the orchestration layer that applies scaling plans across multiple resources, while EC2 Auto Scaling is just one component. A useful memory tip: think of AWS Auto Scaling as the "brain" that decides when to scale, and EC2 Auto Scaling as the "muscle" that executes it.
This PAS-C01 practice question tests your understanding of design of sap workloads on aws. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is deploying SAP Business Suite on AWS. They need to ensure that the SAP system can handle a sudden increase in user load without manual intervention. Which AWS service should be used to automatically scale the SAP application servers?
AWS Lambda
Why wrong: Lambda is for event-driven code execution, not for scaling EC2.
Amazon Elastic Container Service
Why wrong: ECS is for containerized applications, not typical SAP NetWeaver.
Elastic Load Balancing
Why wrong: ELB distributes traffic but does not automatically scale instances.
AWS Auto Scaling
Auto Scaling adjusts the number of EC2 instances automatically.

Correct answer & explanation
AWS Auto Scaling
AWS Auto Scaling is the correct service because it automatically adjusts the number of SAP application server instances based on demand, using scaling policies tied to metrics like CPU utilization or memory. This ensures the SAP system can handle sudden user load spikes without manual intervention, which is a core requirement for elastic SAP deployments on AWS.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
AWS Lambda
Why it's wrong here
Lambda is for event-driven code execution, not for scaling EC2.
Amazon Elastic Container Service
Why it's wrong here
ECS is for containerized applications, not typical SAP NetWeaver.
Elastic Load Balancing
Why it's wrong here
ELB distributes traffic but does not automatically scale instances.
AWS Auto Scaling
Why this is correct
Auto Scaling adjusts the number of EC2 instances automatically.

Common exam traps
The trap here is that candidates often confuse Elastic Load Balancing with auto-scaling, thinking that load balancing alone provides elasticity, but ELB only distributes traffic and does not manage instance count.
Detailed technical explanation
AWS Auto Scaling for SAP uses dynamic scaling policies that can react to CloudWatch alarms based on SAP-specific metrics (e.g., SAPS or dialog step response time) or custom metrics. Under the hood, Auto Scaling launches new EC2 instances from a pre-configured AMI and registers them with the load balancer, ensuring the SAP application layer can scale out within minutes. In real-world scenarios, you must also configure the SAP start profile and host auto-registration to ensure new instances join the SAP system landscape automatically.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
