Introduction

While I was doing engineering, one of my teachers encouraged me to learn about AWS (Amazon Web Service). That was the time when my journey to learn more about AWS started. During my research, I learned about Amazon Elasticache, and the concept of Elasticache amazed me so much. So today, I will be sharing all the valuable details about it. 

In this article, we will discuss the definition of Amazon Elasticache, its types, benefits, and working. Further, we will look at Amazon ElastiCache for Redis Global Datastore.

Amazon Elasticache

Amazon Elasticache is a service that permits you to create, operate, and scale open-source well-matched in-memory data stores within the cloud easily. Simply, it means that this removes the complexity of setting up and handling a distributed cache environment. The technology itself is made to enhance the overall performance of web-based apps by reducing the database load via a quick retrieval of data from high throughput and low latency in-memory data stores. You can think about it as a high-performance caching machine that facilitates demanding web apps requiring a fast response.

Types of Elasticache

ElastiCache Memcached

Amazon ElastiCache for Memcached is a Memcached-well matched in-memory key-value store service that may be used as a cache or a data store. It provides performance, ease of use, and simplicity of Memcached. ElastiCache for Memcached is completely secure, scalable, and managed- making it a perfect candidate for use cases in which frequently accessed data must be in-memory. It is a famous choice for use cases inclusive of Mobile Apps, Web, Gaming, E-Commerce, and Ad-Tech.

ElastiCache Redis

AWS ElastiCache is a controlled caching service well suited to both Redis and Memcached. When it comes to Redis, ElastiCache provides a wholly managed platform that makes it easy to operate, deploy, and scale a high-performance distributed in-memory datastore cluster. These abilities can notably decrease the operational overhead in maintaining machines, software patching, backups, failure recovery, and monitoring.

AWS ElastiCache is completely compatible with the standard Redis data structures, clients, and APIs, permitting your current applications that already use Redis to start using ElastiCache without any code changes. It supports both Redis cluster and non-cluster modes, offering improved high availability and reliability, with automated failover scenarios throughout availability zones.

Benefits of Amazon Elasticache

  • Easily Scalable: Amazon ElastiCache permits you to start small and then progressively scale up your abilities as the application grows. You can, for instance, amplify your Redis cluster environment to as much as 500 shards and 500 nodes, plus probably even increase your cluster’s in-memory data up to 340TB. Then in case you want to reduce costs, you can scale down the resources without experiencing any form of downtime.
  • Completely managed: ElastiCache is a completely-managed cloud-based solution. This means that when you experience the advanced caching capabilities, you don’t have to worry about failure recovery, backups, monitoring, setups, configuration, software patching, and hardware provisions. The service will deal with all that while, at the same time, continuously monitoring your clusters to maintain your Redis operating efficiently.
  • Highly available: AWS ElastiCache achieves high availability via automatic failover detection and mitigation. Primary node failures are instantly resolved by standby replicas. The same applies to reading operations; if the primary one is busy, then the read replicas will come into action to serve the data and maintain your software running smoothly.

It works as a real-time application in gaming, media-streaming, ride-hailing, and social media, which needs fast access.

The data is further kept in the database that is blazing rapid and used for the database, message broker, queue, and cash. The consumer also can Store temporary data in memory for a sub-millisecond response.

The output is impressive as it is reliable, durable, scalable, and flexible.

Amazon ElastiCache for Redis - Global Datastore

Source-Link

Global Datastore for Redis functionality allows you to work with completely managed cross-region replication quickly, securely, and reliably. Each Global Datastore is a group of one or more than one clusters that replicates data with each other. To use cross-region replication, you have at least 2 clusters, i.e., Primary and Secondary, or Active and Passive, respectively configured. The primary cluster is read/write; simultaneously, the cluster secondary is just read and has to be in any other region.

Frequently Asked Questions

What type of service is Elasticache?

Amazon ElastiCache is a completely managed in-memory data store and cache service by AWS. The provider improves the overall performance of web applications by retrieving data from managed in-memory caches in place of relying totally on slower disk-based databases.

How do I enable ElastiCache in AWS?

Open the AWS Management Console in your browser and navigate to ElastiCache. Click the blue “Create” button towards the center of the page. For this cluster, we can choose the Redis engine and enable Cluster-Mode. Next, give your cluster a name and description.

What is an ElastiCache node?

The smallest building block of an Amazon ElastiCache deployment is known as the Elasticache node.
