Amazon ElastiCache vs Amazon Redshift: What are the differences?

Introduction

Amazon ElastiCache and Amazon Redshift are two widely used services provided by Amazon Web Services (AWS) for managing data storage and processing. While they both serve different purposes, there are key differences between the two that make them suitable for specific use cases.

  1. Scalability and Performance: Amazon ElastiCache is a fully managed in-memory data store that provides high performance and low-latency access to frequently accessed data. It is designed for caching and real-time data processing, making it ideal for use cases where low latency is crucial, such as real-time application dashboards or session management. On the other hand, Amazon Redshift is a fully managed data warehousing service that allows users to query and analyze large datasets with high performance. It is optimized for online analytical processing (OLAP) and provides the ability to run complex queries across petabytes of data.

  2. Data Persistence: ElastiCache is primarily an in-memory data store and is not suitable for persistent data storage. It uses a cache eviction policy to manage the data in memory, which means that data may be evicted based on predefined rules. On the other hand, Amazon Redshift provides persistent storage for large datasets and can retain data over a longer period. It uses columnar storage and compression techniques to optimize storage and query performance.

  3. Data Structure and Querying: ElastiCache supports key-value-based data structures like Redis and Memcached, making it suitable for applications that require simple data retrieval and caching. It does not provide advanced querying capabilities. On the other hand, Amazon Redshift supports SQL-based querying, allowing users to perform complex queries and aggregations on structured data. It provides a rich set of SQL functions and extensions to optimize analytical workloads.

  4. Data Consistency and Durability: ElastiCache does not provide built-in durability and replication mechanisms. It relies on replication techniques provided by Redis or Memcached to ensure data availability and reliability. In contrast, Amazon Redshift automatically replicates data across multiple nodes within a cluster to ensure high availability and durability. It provides built-in backup and restore mechanisms to support data recovery.

  5. Cost Structure: ElastiCache pricing is based on the size of the cache nodes and the amount of data transferred in and out of the cache. It is typically priced on an hourly basis. On the other hand, Amazon Redshift pricing is based on the compute resources consumed and the amount of data stored. It is typically priced per hour and per terabyte of data stored.

  6. Use Cases: ElastiCache is commonly used for caching frequently accessed data, reducing database load, and improving application performance. It is suitable for use cases such as session management, real-time analytics, and high-traffic websites. Amazon Redshift, on the other hand, is designed for large-scale data warehousing and analytical workloads. It is suitable for data analysis, business intelligence, and data exploration.

In summary, Amazon ElastiCache is a high-performance in-memory caching service suitable for real-time data processing and low-latency access, while Amazon Redshift is a scalable data warehousing service optimized for querying and analyzing large datasets.

Needs adviceonAmazon EC2Amazon EC2TableauTableauPowerBIPowerBI

We need to perform ETL from several databases into a data warehouse or data lake. We want to

  • keep raw and transformed data available to users to draft their own queries efficiently
  • give users the ability to give custom permissions and SSO
  • move between open-source on-premises development and cloud-based production environments

We want to use inexpensive Amazon EC2 instances only on medium-sized data set 16GB to 32GB feeding into Tableau Server or PowerBI for reporting and data analysis purposes.

Detailed Comparison

Amazon Redshift
Amazon Redshift
Amazon ElastiCache
Amazon ElastiCache

It is optimized for data sets ranging from a few hundred gigabytes to a petabyte or more and costs less than $1,000 per terabyte per year, a tenth the cost of most traditional data warehousing solutions.

ElastiCache improves the performance of web applications by allowing you to retrieve information from fast, managed, in-memory caches, instead of relying entirely on slower disk-based databases. ElastiCache supports Memcached and Redis.

Optimized for Data Warehousing- It uses columnar storage, data compression, and zone maps to reduce the amount of IO needed to perform queries. Redshift has a massively parallel processing (MPP) architecture, parallelizing and distributing SQL operations to take advantage of all available resources.;Scalable- With a few clicks of the AWS Management Console or a simple API call, you can easily scale the number of nodes in your data warehouse up or down as your performance or capacity needs change.;No Up-Front Costs- You pay only for the resources you provision. You can choose On-Demand pricing with no up-front costs or long-term commitments, or obtain significantly discounted rates with Reserved Instance pricing.;Fault Tolerant- Amazon Redshift has multiple features that enhance the reliability of your data warehouse cluster. All data written to a node in your cluster is automatically replicated to other nodes within the cluster and all data is continuously backed up to Amazon S3.;SQL - Amazon Redshift is a SQL data warehouse and uses industry standard ODBC and JDBC connections and Postgres drivers.;Isolation - Amazon Redshift enables you to configure firewall rules to control network access to your data warehouse cluster.;Encryption – With just a couple of parameter settings, you can set up Amazon Redshift to use SSL to secure data in transit and hardware-acccelerated AES-256 encryption for data at rest.<br>
Support for two engines: Memcached and Redis;Ease of management via the AWS Management Console. With a few clicks you can configure and launch instances for the engine you wish to use.;Compatibility with the specific engine protocol. This means most of the client libraries will work with the respective engines they were built for - no additional changes or tweaking required.;Detailed monitoring statistics for the engine nodes at no extra cost via Amazon CloudWatch;Pay only for the resources you consume based on node hours used
