Amazon Elasticsearch Service
for Real-time Data Analysis and
Visualization
Amazon Elasticsearch Service
What to Expect from the Session
• Context: Managing your growing data
• Introducing Amazon Elasticsearch Service (Amazon ES)
• Configuring, securing, connecting, monitoring, and
scaling your Amazon ES cluster
Your data is constantly growing
Product usage
Your data is constantly growing
System logs
Your data is constantly growing
Customer conversations
That’s a lot of data!
“Big data is not about the data”- Gary King, Harvard University, making the point that while data is
plentiful and easy to collect, the real value is in the analytics.
So what can you do with all this data?
• Share information
• Extract insight
• Recognize patterns
• Track performance
Ultimately, make better business,
technical, and operational decisions
Scenario 1: Full-text search
Knowledge Sharing Systems
• Your team is constantly generating
content
• You are tasked with making this
knowledge base searchable and
accessible
• You need key search features including
text matching, faceting, filtering, fuzzy
search, auto complete, and highlighting
Scenario 2: Streaming data analytics
Intrusion detection
• You have to protect your system from
attacks
• You need easy to use, yet powerful
analytics and data visualization tools to
detect issues in near real-time
• Easy and flexible data ingestion is
important to capture information from a
variety of key data sources
Scenario 3: Batch data analytics
Usage Monitoring
• You are a mobile app developer
• You have to monitor/manage users
across multiple app versions
• You want to analyze and report on
usage and migration between app
versions
What options do you have?
How Elasticsearch can help
A powerful, real-time, distributed, open-source search and
analytics engine:• Built on top of Apache Lucene
• Schema free
• Developer friendly RESTful API
How Elasticsearch can help
Combined with Logstash and Kibana, the ELK stack
provides a tool for real-time analytics and data visualization
Operating Elasticsearch is time-consuming
“Elasticsearch allows us to easily and quickly build bleeding edge big data
and analytics applications using the ELK stack. By offering direct access
to the Elasticsearch API while offloading administrative tasks, Amazon
Elasticsearch Service gives us the manageability, flexibility and control we
need ”
Sean Curtis, SVP Engineering at Major League
Baseball Advanced Engineering
Introducing Amazon Elasticsearch Service
Amazon Elasticsearch Service is
a managed service from AWS that
makes it easy to set up, operate,
and scale Elasticsearch clusters
in the cloud.
Key benefits

Monitoring
What should I monitor?
• FreeStorageSpace – monitor and alarm before the
cluster runs out of space
• CPUUtilization – alarm at 80% CPU to signal the need to
scale up
• ClusterStatus.yellow – check whether replication
requires additional nodes
• JVMMemoryPressure – check instance type and count
for sufficient resources
• MasterCPUUtilization – monitoring for master nodes is
separated from data nodes
Snapshot and
restore for data
durability
Daily automated snapshots
• No additional charges
• Snapshots retained for 14 days
