An application ingests a large number of small messages and stores them in a database. The application uses AWS Lambda. A development team is making changes to the application's processing logic. In testing, it is taking more than 15 minutes to process each message. The team is concerned the current backend may time out.
Which changes should be made to the backend system to ensure each message is processed in the MOST scalable way1?
In a move toward using microservices, a company’s Management team has asked all Development teams to build their services so that API requests depend only on that service’s data store. One team is building a Payments service which has its own database; the service needs data that originates in the Accounts database. Both are using Amazon DynamoD
B.
What approach will result in the simplest, decoupled, and reliable method to get near-real time updates from the Accounts database?

What is the SAFEST way to meet these requirements?
A Developer must build an application that uses Amazon DynamoD
B.
The requirements state that items being stored in the DynamoDB table will be 7KB in size and that reads must be strongly consistent. The maximum read rate is 3 items per second, and the maximum write rate is 10 items per second.How should the Developer size the DynamoDB table to meet these requirements?
An on-premises legacy application is caching data files locally and writing shared images to local disks.
What is necessary to allow for horizontal scaling when migrating the application to AWS?
An application deployed on AWS Elastic Beanstalk experiences increased error rates during deployments of new application versions, resulting in service degradation for users. The Development team believes that this is because of the reduction in capacity during the deployment steps. The team would like to change the deployment policy configuration of the environment to an option that maintains full capacity during deployment while using the existing instances.
Which deployment policy will meet these requirements while using the existing instances?
A company has a web application that uses an Amazon Cognito user pool for authentication. The company wants to create a login page with the company logo. What should a developer do to meet these requirements?
