Amazon ElastiCache is a fully managed in-memory caching service that increases application performance by reducing latency and the load on databases. ===================================== 2).What is the difference between RDS Read Replicas and Multi-AZ deployments? Read Replicas are read-only copies of a database, useful for scaling read-heavy applications and offloading workloads like reporting. Multi-AZ deployments, however, provide high availability by creating synchronous replicas in another availability zone, ensuring failover support during outages. 3).30. What is the AWS Shared Responsibility Model? The AWS Shared Responsibility Model states the division of responsibility between the customer and the provider. Thus, AWS looks after the infrastructure, hardware and network security related to the cloud, while clients secure their information, applications and user access. 4).35. What is AWS OpsWorks? AWS OpsWorks is a configuration management service that simplifies the deployment and management of applications using Chef or Puppet. It is especially useful for setting up and managing multi-tier architectures. 5).What is Amazon EMR, and when should it be used? Amazon EMR is a big data processing service that uses frameworks like Hadoop and spark. It is Suitable 6).How does Amazon Redshift support data warehousing? Amazon Redshift is a managed data warehouse service that utilizes columnar storage and compression for rapid queries and optimal storage, allowing businesses to swiftly analyze vast datasets such as local sales information.
 7).How does AWS implement CI/CD pipelines? AWS utilizes CodePipeline, CodeBuild, and CodeDeploy to automate the processes of building, testing, and deploying. Developers upload code to GitHub, while CodePipeline streamlines the testing and deployment process, guaranteeing smooth updates to production. 8).What is the purpose of S3 Access Points? S3 Access Points make it easier to manage data access in shared environments. They permit distinct access settings for various users or applications while maintaining security. They are beneficial in multi-tenant settings, offering regulated access according to network or user needs. 9).cWhat is S3 Intelligent-Tiering? S3 Intelligent-Tiering dynamically moves objects among two access tiers: frequent and infrequent based on usage patterns. This saves storage costs without human intervention, making it ideal for data with unpredictable usage patterns. 10).How do you troubleshoot access-denied errors in S3? Review IAM policies, bucket policies and ACLs for proper permissions. Verify that the requesting party has the proper access privileges and check the correct resource path and actions. 11).What is Amazon Aurora, and how does it differ from other RDS engines? Amazon Aurora is a managed relational database that works with MySQL/PostgreSQL, providing superior performance, automatic backups, replication, scalability, and cost-effectiveness in comparison to regular RDS engines. 12).What is Amazon DynamoDB, and what are its use cases? Amazon DynamoDB is a managed NoSQL database that provides excellent performance and minimal latency for applications such as mobile, gaming, and IoT, featuring automated scaling and secure data access. 13).How does Multi-AZ improve database availability in RDS? Multi-AZ in RDS enhances availability by duplicating data to a standby instance located in another Availability Zone, allowing for automatic failover and ongoing application uptime. 14).What is Amazon Redshift, and what are its key features? Amazon Redshift is a flexible data warehousing solution featuring columnar storage, data compression, and parallel query processing, facilitating rapid and effective analysis of large datasets. 15).What is ElastiCache, and how does it improve performance? Amazon ElastiCache is a memory-based data store that stores frequently accessed information, lowering database strain and enhancing response times for real-time applications and high-performance situations. 16). What is Amazon DocumentDB used for? Amazon DocumentDB is a managed NoSQL database that is compatible with MongoDB. It assists applications requiring adaptable data structures, such as content management and real-time analysis. 17).How do you implement DynamoDB Streams? Enable DynamoDB Streams on tables to log changes. Utilize AWS Lambda or Kinesis for immediate processing of data modifications (insertions, updates, deletions). 18).What is Amazon Neptune, and what is it used for? Amazon Neptune is a fully managed graph database designed for storing and querying interconnected information, beneficial for recommendation systems, fraud detection, and knowledge graphs 19).How do database snapshots work in AWS? AWS database snapshots serve as backups from a specific moment in time. Both automated and manual snapshots can be recovered in Amazon RDS for the purpose of data consistency and recovery. 20).
