AWS Database » Elasticsearch
by Abhinav Singh
2y ago
September 8, 2021: Amazon Elasticsearch Service has been renamed to Amazon OpenSearch Service. See details. We’re excited to announce the addition of a new target in AWS Database Migration Service (AWS DMS)—Amazon Elasticsearch Service. You can now migrate data to Amazon Elasticsearch Service from all AWS DMS–supported sources. With support for this new target, you can use DMS in your data integration pipelines to replicate data in near-real time into Amazon Elasticsearch Service. Amazon Elasticsearch Service is a fully managed service that makes it easy for you to deploy, secure, and operate ..read more

Serverless Scaling for Ingesting, Aggregating, and Visualizing Apache Logs with Amazon Kinesis Firehose, AWS Lambda, and Amazon Elasticsearch Service

Pubali Sen and Shankar Ramachandran are solutions architects at Amazon Web Services. In 2016, AWS introduced the EKK stack (Amazon Elasticsearch Service, Amazon Kinesis, and Kibana, an open source plugin from Elastic) as an alternative to ELK (Amazon Elasticsearch Service, the open source tool Logstash, and Kibana) for ingesting and visualizing Apache logs. One of the main features of the EKK stack is that the data transformation is handled via the Amazon Kinesis Firehose agent. In this post, we describe how to optimize the EKK solution—by handling the data transformation in Amazon Kinesis F ..read more

Send Apache Web Logs to Amazon Elasticsearch Service with Kinesis Firehose
AWS Database » Elasticsearch
by Jon Handler
5y ago
We have many customers who own and operate Elasticsearch, Logstash, and Kibana (ELK) stacks to load and visualize Apache web logs, among other log types. Amazon Elasticsearch Service provides Elasticsearch and Kibana in the AWS Cloud in a way that’s easy to set up and operate. Amazon Kinesis Firehose provides reliable, serverless delivery of Apache web logs (or other log data) to Amazon Elasticsearch Service. With Firehose, you can add an automatic call to an AWS Lambda function to transform records within Firehose. With these two technologies, you have an effective, easy-to-manage replacemen ..read more

Darin Briskman (@briskmad) is a technical evangelist at Amazon Web Services. So you’re working with Amazon Elasticsearch Service and you’re setting up a non-production domain, using it for a development, sandbox, test, or staging environment. (If you’re new to Elasticsearch, a domain is similar to what’s called a cluster for other computing systems. It’s a collection of servers, network, and software working as a single system.) You’ll initially want to throw some data at Elasticsearch, pop off a couple of commands using curl, and check in with Kibana. You know you should set up a secure env ..read more

James Huang is an enterprise solutions architect at Amazon Web Services. AWS recently announced support for Elasticsearch 5.1. The announcement mentioned a few important improvements in the open source software and in Amazon Elasticsearch Service (Amazon ES), the managed service.  Elasticsearch 5.1 includes three important changes: a new scripting language called Painless, significant improvements to indexing throughput, and a new ingest model, which is described in this blog post. Many operations teams use Logstash or homegrown pipelines of data transformation scripts and tools to modify lo ..read more

Get Started with Amazon Elasticsearch Service: How Many Shards Do I Need?
AWS Database » Elasticsearch
by Jon Handler
5y ago
Welcome to this introductory series on Elasticsearch and Amazon Elasticsearch Service (Amazon ES). In this and future articles, we provide the basic information that you need to get started with Elasticsearch on AWS. How many shards? Elasticsearch can take in large amounts of data, split it into smaller units, called shards, and distribute those shards across a dynamically changing set of instances. When you create an Elasticsearch index, you set the shard count for that index. Because you can’t change the shard count of an existing index, you have to make the decision on shard count before ..read more

Set Access Control for Amazon Elasticsearch Service
AWS Database » Elasticsearch
by Jon Handler
5y ago
Securing your Amazon Elasticsearch Service (Amazon ES) domain helps ensure your data cannot be accessed or altered by unauthorized users. Most customers want the security of IP address- or identity-based access policies, but choose open access out of convenience. Because a domain with open access will accept requests to create, view, modify, and delete data from the Amazon ES domain from any party on the Internet, this option is not appropriate for most customers. In an earlier blog post, How to Control Access to Your Amazon Elasticsearch Service Domain, we explored access control in depth. I ..read more

Get Started with Amazon Elasticsearch Service: How Many Data Instances Do I Need?

Welcome to the first in a series of blog posts about Elasticsearch and Amazon Elasticsearch Service, where we will provide the information you need to get started with Elasticsearch on AWS. How many instances will you need? When you create an Amazon Elasticsearch Service domain, this is one of the first questions to answer. To determine the number of data nodes to deploy in your Elasticsearch cluster, you’ll need to test and iterate. Start by setting the instance count based on the storage required to hold your indices, with a minimum of two instances to provide redundancy. Storage Nee ..read more

Indexing Metadata in Amazon Elasticsearch Service Using AWS Lambda and Python
AWS Database » Elasticsearch
by Amit Sharma
5y ago
Amit Sharma (@amitksh44) is a solutions architect at Amazon Web Services. You can use Amazon S3 to implement a data lake architecture as the single source of truth for all your data. Taking this approach not only allows you to reliably store massive amounts of data but also enables you to ingest the data at a very high speed and do further analytics on it. Ease of analytics is important because as the number of objects you store increases, it becomes difficult to find a particular object—one needle in a haystack of billions. Objects in S3 contain metadata that identifies those objects along ..read more

Implementing Alerting on Amazon Elasticsearch Data
AWS Database » Elasticsearch
by Yash Pant

Yash Pant is a solutions architect in Amazon Web Services Amazon Elasticsearch Service (Amazon ES) customers often ask how to implement alerting on information that is being indexed by their Amazon Elasticsearch domain. In this blog post, I will discuss the steps required to set up an alerting mechanism so that you can send near real-time alerts based on criteria you define. The Approach To set up alerting, we will use the scheduled event trigger in AWS Lambda, which allows a Lambda function to execute at a fixed rate (for example, every minute). Our Lambda function will contain Elasticsear ..read more
