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 atomicity, consistency, isolation, and durability (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 take the following steps:

  • Use a database that supports ACID: The first step is to choose a database that supports ACID. Amazon RDS provides managed database services for several popular relational database engines that support ACID, including MySQL, PostgreSQL, and Oracle.
  • Use a database replica for read scalability and failover: Create a database replica to offload some of the read traffic from the master instance, reduce the load on the master instance, and improve its performance. The replica can also be used for failover in case of a breakdown. Amazon RDS provides managed database replication for MySQL, PostgreSQL, and Oracle.
  • Use Amazon EBS snapshots for backup and disaster recovery: Amazon EBS snapshots can be used to back up EBS volumes and restore them in case of failure. Snapshots can also be used to create new EBS volumes, making it easy to replicate data across multiple instances.
  • Use Amazon S3 for object storage: Amazon S3 provides a durable and scalable object storage service that can be used to store static content, such as images, videos, and files. S3 is designed to provide 11 nines of durability, meaning that data is stored across multiple devices in multiple facilities, making it highly resilient in the event of a breakdown.
  • Use Amazon Route 53 for DNS failover: Amazon Route 53 provides a DNS failover service that can be used to route traffic to healthy instances in the event of a breakdown. Route 53 can monitor the health of EC2 instances and automatically route traffic to alternate instances in case of a failure.
  • Use Amazon CloudWatch for monitoring: Amazon CloudWatch can be used to monitor the health of EC2 instances, EBS volumes, RDS instances, and other AWS resources. CloudWatch provides metrics, logs, and alarms that can be used to identify and respond to issues in real time.
