Amazon CloudSearch vs ElasticSearch

• CloudSearch is a managed service
  • no agents to install
  • no servers to manage
• Elastic Search
  • requires ElasticSearch agent
  • runs on EC2 instances

Amazon Inspector

• automated security assessment
• network assessment check does not require agent install

Kinesis Data Streams Performance

• develop code using Kinesis Producer Library to put data onto the streams
• use a Small Producer with the Kinesis Producer Library
  • but use PutRecord operation
• Check Service Limits
  • GetShardIterator
  • CreateStream
  • DescribeStream
• Always use the KPL when writing code for Kinesis, where possible
  • Benefits: Performance, Monitoring, Asynch Performance

Kinesis Stream Re-Sharding Error

• scaled stream by increasing consumers (KCL) and re-sharding the stream
• after re-sharding an extra shard was produced
  • this sometimes occurs when size of a shard is very small, like '1'
• resolve by merging small shard with adjacent shard
• the difference between StartingHashKey and EndingHashKey is normally large
