Preparing for the AWS Certified SysOps Administrator – Associate (SOA-C02) exam requires in-depth knowledge and practical experience with various AWS services. In this article, we’ll explore the process of scheduling automated tasks using AWS services such as EventBridge and AWS Config.
1. Scheduling Automated Tasks with AWS EventBridge
AWS EventBridge is a serverless event bus that connects your applications with data from a variety of sources. EventBridge is deeply integrated with AWS infrastructure, making it simpler to build event-driven applications.
Consider a standard user scenario where you want to schedule a Lambda function to run at a specific time every day. Here’s how you might set this up with EventBridge:
- Create a new rule in EventBridge.
- For the event pattern, choose “Schedule”.
- Specify the frequency (for instance, “cron(0 12 * * ? *)” to run the function everyday at 12 PM UTC).
- In the Targets section, select “AWS Lambda function” and choose the appropriate function.
Once the rule is set up, your Lambda function will be invoked according to the schedule you specified.
2. Automating Compliance Checks with AWS Config
AWS Config is a service that lets you inspect, evaluate, and audit your AWS resources according to desired configurations. This becomes particularly useful in scenarios where you need to enforce certain standards or compliance regulations.
For example, you can use AWS Config to ensure that all your Amazon S3 buckets block public access. Here’s a simple set of steps to achieve this:
- Set up AWS Config and select the S3 bucket resource type.
- Create a Config rule that checks whether all S3 buckets have the ‘Block all public access’ setting enabled.
- If a bucket doesn’t meet this condition, AWS Config flags it as non-compliant.
AWS Config offers a variety of managed rules for compliance checks, but you can also create custom rules using AWS Lambda.
3. Comparing EventBridge and AWS Config
| EventBridge | AWS Config | |
|---|---|---|
| Purpose | To schedule automated tasks and connect applications with data from various sources | To evaluate the configuration of AWS resources and evaluate compliance |
| Use Cases | Time-based scheduling, event-driven application development | Compliance checks, resource tracking, configuration audits |
| Integration | Deep integration with AWS resources and third-party SaaS applications. | Works with AWS resources |
In conclusion, scheduling automated tasks and managing configuration compliance are key competencies for the AWS Certified SysOps Administrator – Associate (SOA-C02) exam. Through the use of AWS services like EventBridge and AWS Config, you can efficiently automate and manage your tasks, ensuring optimum resource utilization and regulatory compliance.

True or False: AWS Config helps you schedule tasks by triggering Lambda functions at specified intervals.
- True
- False
Answer: False
Explanation: AWS Config does not schedule tasks or trigger Lambda functions. It primarily provides a detailed view of the configuration of AWS resources.

- a) AWS EventBridge
- b) AWS Config
- c) Amazon S3
- d) AWS CloudWatch
Answer: a) AWS EventBridge
Explanation: AWS EventBridge can make this possible by providing a cron-like functionality to execute scheduled tasks such as Lambda functions.
True or False: AWS Config supports auditing and evaluating the configurations of your AWS resources.
- True
- False
Answer: True
Explanation: AWS Config helps you assess, audit, and evaluate the configurations of your AWS resources.
