Today’s organizations must carefully select the right combination of components in order to achieve their business goals. This includes considering operational cost, efficiency, speed, and speed. A caching solution is also a great option for cloud-native apps. Implementing AWS ElastiCache or Redis can make a significant difference in providing better performance and a great user experience.
What is ElastiCache Server?
Amazon ElastiCache, a web service, is used to deploy, scale, and manage an in-memory cache inside the cloud. It offers a high-performance, resizable and efficient in-memory cache and removes the complexity associated with managing a distributed cache environment.
It supports two cache engines in-memory:
Memcached is an ASCII text file object caching system. ElastiCache can be used with Memcached protocol compliant. All tools that are compatible with existing Memcached environments may be used with ElastiCache.
Redis is an open-source, in-memory key/value store that supports information structures such as lists and sorted sets. AWS ElastiCache conjointly offers master/slave replication as well as multi-AZ. This will allow for cross-AZ redundancy.
This improves web application performance because data is retrieved from fast, managed-in-memory caches instead of slow disk-based databases. AWS ElastiCache also detects and replaces failed nodes. This reduces overhead and reduces the risk of overloaded databases that could cause slow website or application load times. AWS CloudWatch allows users to view key performance metrics for their Memcached and Redis nodes by de-segregating them.
Redis vs. Memcached

Simple steps to start an ElastiCache Redis Server
Sign in to the AWS Management Console, and open the ElastiCache console at https://console.aws.amazon.com/elasticache/.

Select the Subnet Groups from the navigation menu.
Select Create Subnet Group.
Do the following in the Create Subnet Group wizard. Once you have made all settings as you wish, click Yes to Createa. Type a name for the subnet group in the Name box. In the Description box, enter a description of your subnet group. In the VPC ID box select the Amazon VPC you createdc. Select your private subnet’s Availability Zone or Subnet ID list, then click Add
Click on Create in Subnet Group
Click on ElastiCache Dashboard to Get Started
Select Redis from the navigation panel
Select Create.
Redis is the best choice for Cluster engine. Make sure you have cleared the Cluster-Mode enabled box
Complete the remaining steps based on the requirement
Launch an EC2Note : In the ElastiCache security groups, the instance security group should open on port 6379
Install Redis-cli from the $ sudo apat install redis1$ suo apt installer redis
Run the following command$ redis-cli -h redis-primary-endpoint -p 63791$ redis-cli -h redis-primary-endpoint -p 6379
Benefits of ElastiCache Server
Simple to deploy:
It deploys a Memcached and Redis-compliant environment with the help of Amazon web Services Console. It can be deployed without worrying about infrastructure provisioning, installing, or maintaining cache software.
Managed:
ElastiCache automates the tedious management tasks such as patch management, recovery and failure detection. This allows users to concentrate on application development.
Compatible:
ElastiCache gives native access to in-memory cache environments such as Memcached and
