Scenario 1:
You have to tell me the tradeoff, options
You are working for a growing eCommerce company. Their current application is a large monolith application running on VM or Ec2. Their deployments are manual, slow, which results into frequent production issues and required lengthy rollbacks. This severely impacting the tendency of team to release new features. As a solution architect, how would you redesign the deployment and infrastructure architecture for operational excellence.
Q: What is AWS Xray?
Q: How can we do blue green strategy with cloud platforms, say example Azure?
Q: What is regression testing.
Q: What is penetrating testing. how I can test regression and penetration testing.
Q: How you can plugin multiple testing in azure pipeline?
Q(Imp): Consider the above application is also having the database to persist the data, as part of deployment there are changes in databasea as well, now if you have to roll back. What will be your strategy to roll back the database changes?

Scenario 2:
There is big logicstic company which runs a shipment tracking application, that need to be available 24X7. Their current architecture is deployed on single AWS/ Azure region. They ahve business requirement of RTO less than 10mins and RPO less than 1 min. As an architect tell me the strategy you will plan it for this type of requirement.
Q: What are the different ways by which we can work on RPO and RTO.
Q: What is AWS X-Ray?
Q: TEll me the ways by which you can scale the relation database?
Scenario 3: A startup hosted a application in AWS, their monthly bill going very high and its not in propotion to the growth of users on their application. They are running the entire workflow on stateless webapps/ microservices, databases, and tehre many nightly batch process jobs. All of these are running on on demand Ec2 Instances. Propose an strategy to optimize the cost without performance and liability of existing application.
Scenarion 4: There is again an ecommerace application. Where they have two pages 1) product displahy page, where user can go check about the details of the product. check photos etc. On this page we also show the inventory of the product, how much product is left in inventory, but this value could be worng and it need not be actual value. The page must response very fast. Performance is the key on this page.
2nd is the checkout page, where users will select the product and do the payment. Here the information of the inventory count must be correct and 100% accurate.
As a solution architect how will you design the system which satisfy both the requirements and how you will manage the dataflow between these two components. wahat type of consistency model you will choose for both the components,
