Q11: AWS Data Lifecycle Manager (DLM)
AWS Data Lifecycle Manager (DLM) is a service provided by Amazon Web Services (AWS) that enables users to automate the process of creating, retaining, and deleting backups of their Amazon Elastic Block Store (EBS) volumes and Amazon EC2 instances. DLM provides a simple, automated way to manage the lifecycle of your AWS resources by defining policies that automate snapshot management.
Q12: AWS Aurora Read replicas
Amazon Aurora is a MySQL and PostgreSQL-compatible relational database built for the cloud, that combines the performance and availability of traditional enterprise databases with the simplicity and cost-effectiveness of open source databases. Amazon Aurora Replicas increase compute capacity within your Aurora MySQL DB cluster. They help in distributing read workload (read scaling) within the region and also act as failover targets. This means that if your primary DB instance fails, an Aurora replica is then promoted to the primary instance.
Q14: AWS Fargate
AWS Fargate is a compute engine for Amazon ECS (Elastic Container Service) and Amazon EKS (Elastic Kubernetes Service) that allows you to run Docker containers without having to manage the underlying infrastructure.
Q15: ecs autoscaling target tracking policy
An ECS autoscaling target tracking policy is a type of policy that is used to automatically adjust the size of an ECS cluster based on a predefined target metric . This type of policy is often used to maintain a specific level of resource utilization, such as CPU or memory, in order to ensure that the cluster is able to handle the workload efficiently without being over-provisioned.
Q16: AWS DataSync
AWS DataSync is an online data transfer service that simplifies, automates, and accelerates moving data between on-premises storage systems and AWS storage services. DataSync can copy data between Network File System (NFS) file servers, Server Message Block (SMB) file servers, Hadoop Distributed File System (HDFS).
it also provides scheduled synchronisation
Q16: AWS Glue
it is an ETL service
Q17: AWS FSx Lustre
Amazon FSx for Lustre is a high-performance file system optimized for computing-intensive workloads, such as machine learning, high-performance computing (HPC), and video processing. It is built on Lustre, an open-source parallel file system , and is designed to provide high throughput, low latency, and high input/output (I/O) operations per second (IOPS) for large-scale data processing.
Q18: AWS WAF
AWS WAF (Web Application Firewall) is a managed service that provides protection for your web applications against common web exploits and attacks. It allows you to create custom rules to block specific web traffic that is malicious or undesirable, such as SQL injection, cross-site scripting (XSS), and bot attacks. AWS WAF can be used to block specific patterns or signatures in the HTTP request or response, such as known DDoS attack vectors. You can configure AWS WAF to block traffic from known malicious IPs or IP ranges, and also use rate-based rules to limit the number of requests per IP address.
Q20: DynamoDB
provides near real-time performance and milisecond responsiveness
