Which of the following can an AWS customer use to launch a new ElastiCache cluster select two?
Clusters are simple to create, using the AWS Management Console, Amazon ElastiCache APIs, or Command Line Tools. To launch a cluster using the AWS Management Console, click on the "Create" button in either the “Memcached” or “Redis” tab.
Does ElastiCache for Redis support multi AZ?
You can enable Multi-AZ using the ElastiCache console when you create a new Redis cluster or by modifying an existing Redis cluster with replication. Multi-AZ is enabled by default on Redis (cluster mode enabled) clusters.
What type of AWS service is ElastiCache an example of?
Amazon ElastiCache is a fully managed, in-memory caching service supporting flexible, real-time use cases.
Which AWS tools can be used for automation?
AWS OpsWorks is a configuration management service that uses Chef, an automation platform that treats server configurations as code. OpsWorks uses Chef to automate how servers are configured, deployed, and managed across your Amazon Elastic Compute Cloud (Amazon EC2) instances or on-premises compute environments.
How do you use cache in Java?
To create a cache, we can simply use a map / dictionary data structure and we can get the expected result of O(1) for both get and put operation. But, we can't store everything in our cache. We have storage and performance limits.
How to retrieve data from cache in Java?
You can fetch a custom object from the cache using various overloads of the Get() method by specifying the key of the cache item. The object is retrieved as a template, so it needs to be type-cast accordingly if it is a custom class object.
