Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company stores its application logs in an Amazon CloudWatch Logs log group. A new policy requires the company to store all application logs in Amazon OpenSearch Service (Amazon Elasticsearch Service) in near-real time.
Which solution will meet this requirement with the LEAST operational overhead?

  • A. Configure a CloudWatch Logs subscription to stream the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service).
  • B. Create an AWS Lambda function. Use the log group to invoke the function to write the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service).
  • C. Create an Amazon Kinesis Data Firehose delivery stream. Configure the log group as the delivery streams sources. Configure Amazon OpenSearch Service (Amazon Elasticsearch Service) as the delivery stream's destination.
  • D. Install and configure Amazon Kinesis Agent on each application server to deliver the logs to Amazon Kinesis Data Streams. Configure Kinesis Data Streams to deliver the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service).

Zerotn3 is right! There should be a Lambda for writing into ES

Option A (Configure a CloudWatch Logs subscription to stream the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service)) is not a suitable option, as a CloudWatch Logs subscription is designed to send log events to a destination such as an Amazon Simple Notification Service (Amazon SNS) topic or an AWS Lambda function. It is not designed to write logs directly to Amazon Elasticsearch Service (Amazon ES).

that is not true, you can stream logs from CloudWatch Logs directly to OpenSearch

Selected Answer: C
The correct answer is C: Create an Amazon Kinesis Data Firehose delivery stream. Configure the log group as the delivery stream source. Configure Amazon OpenSearch Service (Amazon Elasticsearch Service) as the delivery stream's destination. This solution uses Amazon Kinesis Data Firehose, which is a fully managed service for streaming data to Amazon OpenSearch Service (Amazon Elasticsearch Service) and other destinations. You can configure the log group as the source of the delivery stream and Amazon OpenSearch Service as the destination. This solution requires minimal operational overhead, as Kinesis Data Firehose automatically scales and handles data delivery, transformation, and indexing.

Option A: Configure a CloudWatch Logs subscription to stream the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service) would also work, but it may require more operational overhead as you would need to set up and manage the subscription and ensure that the logs are delivered in near-real time. Option B: Create an AWS Lambda function. Use the log group to invoke the function to write the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service) would also work, but it may require more operational overhead as you would need to set up and manage the Lambda function and ensure that it scales to handle the incoming logs. Option D: Install and configure Amazon Kinesis Agent on each application server to deliver the logs to Amazon Kinesis Data Streams. Configure Kinesis Data Streams to deliver the logs to Amazon OpenSearch Service (Amazon Elasticsearch Service) would also work, but it may require more operational overhead as you would need to install and configure the Kinesis Agent on each application server and set up and manage the Kinesis Data Streams.

ANSWER A https://docs.aws.amazon.com/opensearch-service/latest/developerguide/integrations.html You can use CloudWatch or Kinesis, but in the Kinesis description it never says real time, however in the Cloudwatch description it does say Real time ""You can load streaming data from CloudWatch Logs to your OpenSearch Service domain by using a CloudWatch Logs subscription . For information about Amazon CloudWatch subscriptions, see Real-time processing of log data with subscriptions.""

In summary, the CloudWatch Logs → Kinesis Data Firehose → Amazon OpenSearch Service (option C) integration is the path recommended by AWS for this type of case. It allows for near real-time transmission, automatic scaling and relatively simple configuration, with the lowest operational overhead .

CloudWatch Logs subscription filter: This is the most straightforward way to stream logs from a CloudWatch Logs group to Amazon OpenSearch Service (Amazon Elasticsearch Service) in near real-time. It eliminates the need for additional components or complex configurations, reducing operational overhead. Direct integration: CloudWatch Logs can directly stream logs to OpenSearch Service without requiring intermediate services, making it a simple and efficient solution. Low operational overhead: Once set up, the subscription filter automatically forwards logs to OpenSearch Service with minimal maintenance.

C for sure Simplicity: Kinesis Data Firehose is a managed service that handles the task of capturing, transforming, and loading data into destinations like Amazon OpenSearch Service. This eliminates the need for complex configuration and management. Scalability: Kinesis Data Firehose can automatically scale to handle varying data volumes, ensuring that logs are ingested in near-real time. Cost-effectiveness: Kinesis Data Firehose is a pay-as-you-go service, making it a cost-effective option for log ingestion and analysis.

I think C is correct because the cloud watch subscription can't stream directly to OpenSearch, it is via Lambda, SNS, FireHouse,....

Correct Answer: C. Create an Amazon Kinesis Data Firehose delivery stream. Configure the log group as the delivery stream's source. Configure Amazon OpenSearch Service (Amazon Elasticsearch Service) as the delivery stream's destination. Explanation: Amazon Kinesis Data Firehose is a fully managed service for delivering real-time streaming data to destinations such as Amazon OpenSearch Service. It requires minimal setup and management, making it a low-overhead solution. By configuring the log group as the source for the Kinesis Data Firehose delivery stream and Amazon OpenSearch Service as the destination, logs can be delivered in near-real time with built-in reliability and scalability.
