In which 3 categories AWS shared responsibility model divider based on the ownership of administrative tasks
1.Fully Managed services (handle all operational tasks and in this fully man6db services only require customer to be responsible for designing data structures and managing access control)
2.Managed services(AWS handle like backup,patching, hardware provisioning tasks and customer take care of db configuration,query optimization and performance tuning decision)
3.Unmanaged service (customer responsible for config, patching, maintenance tasks,database security,backup,high availability setup n performance optimization e.g. MySQL installed on ec2 instance)
Which managed service support multi-AZ deployment and automated backups and multiple db instance types ,also using manually backup creationusing db snapshot
Amazon relational database service( RDS)
Which service provides security features like network isolation, encryption at rest and encryption in transit
Amazon RDS
Which db engines supported by Amazon RDS
Amazon aurora
MySQL
Postgresql
Microsoft SQL server
Mariadb
Oracledb
Select 4 benefit of Amazon RDS :
1.Scalability
2.Cost optimization
3.Multi-AZ Deployment
4.Performance optimization.
5 Security controls
2,3,4,5
Which process reduce pressure on your primary db by storing frequently accessed data in high speed ,easily accessible location
Caching :- data in caching layer stored in system’s memory instead of disk and reduce strain on backend databases by decreasing query volume
Which managed db service help to reduce unnecessary I/O operations and it’s benefits
Amazon aurora and benefits are:
1. High performance and availability(deliver 5 times throughout of std mysql and 3 times of postgresql ,used distributed storage system accross multiple nodes )
2. Automated storage and backup management (automatically storage grows from 10gb to 128tb based on actual data usage and provide continually backup ur db to S3 to provide point-in-time recovery
3. Advanced replication (replicate data across 3 AZ WITH 6 copies of data , provide 99.99percent availability) and fault tolerance
Which service provides automatically scaling with provisioned capacity and data encryption
Amazon Dynamodb
Which service is fully managed No sql db service for both document and key-vakue data structures and fast db option which use flexible schema
Amazon DYNAMODB (give scalability with provisioned capacity, consistent high performance and high availability and durability
Which AWS services support VPC gateway endpoint for a private connection from a VPC
Amazon Dynamodb and Amazon S3(S3 support interface gateway endpoint too)
Which service is fully managed in-memory caching service which used to reduce complexity of administrating in-memory caching systems and automatically detect n replaced failed nodes
Elastic Cache(benefits : high performance for reduce,valkey or Memcached instances
High availability
Replication across multiple availability zones
Data encryption)
Give practical usecases for Elasticcache
Session data management
Database query enhancement
Gaming leather board
Which db with full managed service design to handle semi structured data and compatible with Mongo-DB compatible database and perfect for application requiring frequent schema changes n document oriented data
Amazon DocumentDB(benefits:
MongoDB compatibility
Performance and scalability
Increased read throughput)
Which db service manager json like document with dynamic schemas
Amazon DocumentDB
Which service streamline data protection across AWS resources and on-premises deployments by providing single dashboard for monitoring and managing backups and eliminate complexity of managing multiple backup strategies by supporting multiple storage types including Amazon EBS volume, EFS
AWS backup(benefits:
Centralized backup management
Cross region backup redundancy
Streamlined regulatory compliance)
Which service is fully managed purpose built graph db service which managed highly connected data sets with millisecond latency and excel in understanding complex relationships
Amazon Neptune(benefits:
Purpose built for complex relationships
High performance and scalability)
What are the common tools for caching and while service support all those tools
Redis OSS
Valkey
Memcached
Elasticcache ( improve application performance by delivering microsecond latenctmy for data reads and offloading database queries
Which service used to handled semi structured data like product catalog
Amazon documentdb
Which db service provides enterprise level performance and reliability with cost effective solution by replacing high cost commerce db engines
Amazon Aurora
