- OK, that concludes Domain Five, Defining Operationally Excellent Architectures. In this module, we applied the skills we have learned thus far to select and combine AWS services together to create a highly available website. First, we defined a solution design, based on the requirements that we were given. Then, we implemented our solution in the AWS console, setting up EC2 instances in multiple AZs, setting up an Elastic Load Balancer, and creating an ALDO scale group. We implemented Amazon CloudWatch alarms and triggers, then we reviewed our solution architecture looking for possible improvements and optimizations. And we ended on deciding to implement the Amazon Aurora Database service to optimize for high availability. We identified that automation could be another optimization we could introduce to our solution to create the most operationally excellent architecture possible. We then learned to recognize and explain some of the AWS deployment services available by completing two hands-on labs. First, we deployed a highly available solution using AWS CloudFormation. Then we ran a controlled deployment using AWS Elastic Beanstalk. OK, that concludes domain five of the solution architect associate learning path. Thanks for your attention and we'll see you in the final learning path summary.
