A web-startup runs its very successful social news application on Amazon EC2 with an Elastic Load Balancer, an Auto-Scaling group of Java/Tomcat application-servers, and DynamoDB as data store. The main webapplication best runs on m2 x large instances since it is highly memory- bound Each new deployment requires semi-automated creation and testing of a new AMI for the application servers which takes quite a while ana is therefore only done once per week. Recently, a new chat feature has been implemented in nodejs and wails to be integrated in the architecture. First tests show that the new component is CPU bound Because the company has some experience with using Chef, they decided to streamline the deployment process and use AWS Ops Works as an application life cycle tool to simplify
management of the application and reduce the deployment cycles. What configuration in AWS Ops Works is necessary to integrate the new chat module in the most cost-efficient and flexible way? A. Create one AWS OpsWorks stack, create one AWS Ops Works layer, create one custom recipe B. Create one AWS OpsWorks stack create two AWS Ops Works layers create one custom recipe C. Create two AWS OpsWorks stacks create two AWS Ops Works layers create one custom recipe D. Create two AWS OpsWorks stacks create two AWS Ops Works layers create two custom recipe
