Solutions Architect Professional (Page 105)

A Solutions Architect needs to migrate a legacy application from on premises to AWS.On premises, the application runs on two Linux servers behind a load balancer and accesses a database that is master-master on two servers.Each application server requires a license file that is tied to the MAC address of the server’s network adapter.It takes the software vendor 12 hours to send ne license files through email.The application requires configuration files to use static.IPv4 addresses to access the database servers, not DNS.Given these requirements, which steps should be taken together to enable a scalable architecture for the application servers?

A company runs a memory-intensive analytics application using on-demand Amazon EC2 C5 compute optimized instance.The application is used continuously and application demand doubles during working hours.The application currently scales based on CPU usage.When scaling in occurs, a lifecycle hook is used because the instance requires 4 minutes to clean the application state before terminating.Because users reported poor performance during working hours, scheduled scaling actions were implemented so additional instances would be added during working hours.The Solutions Architect has been asked to reduce the cost of the application.Which solution is MOST cost-effective?Read More →
