Summary

In this chapter, you learned how to review and analyze many log files using native tools found in AWS.

You also had a brief overview of how costs can affect your decisions when choosing the correct storage solution for your long-term log storage for your account and your organization. This overview was presented through the different tiers of storage available in the S3 service and their durability and reliability ratings.

Next, you explored how to move logs out of CloudWatch Logs using subscription filters. You learned that combining CloudWatch subscription filters with the Kinesis Data Firehose service allows you to take incoming logs to CloudWatch Logs and push them into an S3 bucket where they could be stored at lower costs and then be queried by the Amazon Athena service.

You also examined how you could use Kinesis Data Firehose to stream the logs to Amazon OpenSearch, the fast search engine with custom visualizations based on Elasticsearch.
