Amazon Web Services (AWS) is a cloud computing platform provided by Amazon.com that offers a wide range of cloud-based services for businesses and individuals. AWS provides a flexible and scalable infrastructure for hosting websites and applications, storing and analyzing data, running virtual machines, and more. Some of the popular AWS services include Amazon S3 for object storage, Amazon EC2 for virtual machines, Amazon RDS for relational databases, and Amazon Lambda for serverless computing. AWS also offers tools for monitoring, security, and management of cloud resources, making it a comprehensive solution for cloud computing needs.
Multiple Linux Amazon EC2 instances running a web application for a firm are being used, and data is being stored on Amazon EBS volumes. The business is searching for a way to provide storage that complies with atomicity, consistency, isolation, and durability while also increasing the application’s resilience in the event of a breakdown (ACID). What steps should a solutions architect take to fulfill these demands?
To fulfill the demands of ACID while increasing the resilience of a web application running on multiple Linux Amazon EC2 instances and storing data on Amazon EBS volumes, a solutions architect can use a database that supports ACID, create a database replica for read scalability and failover, use AmaRead more
To fulfill the demands of ACID while increasing the resilience of a web application running on multiple Linux Amazon EC2 instances and storing data on Amazon EBS volumes, a solutions architect can use a database that supports ACID, create a database replica for read scalability and failover, use Amazon EBS snapshots for backup and disaster recovery, use Amazon S3 for object storage, use Amazon Route 53 for DNS failover, and use Amazon CloudWatch for monitoring.
See lessOn an EC2 instance, an application of yours is active. Once the CPU usage on your instance hits 80%, you must reduce the load on it. What strategy do you use to complete the task?
To reduce the load on an EC2 instance when its CPU usage hits 80%, one can add more instances, use auto-scaling, use throttling, optimize the application, or use caching. The strategy used will depend on the specific requirements and constraints of the application and environment.
