47. What is the difference between Scalability and Elasticity?
Scalability is the ability of a system to increase its hardware resources to handle the increase in demand. It can be done by increasing the hardware specifications or increasing the processing nodes.
Elasticity is the ability of a system to handle increase in the workload by adding additional hardware resources when the demand increases(same as scaling) but also rolling back the scaled resources, when the resources are no longer needed. This is particularly helpful in Cloud environments, where a pay per use model is followed.

Instance performs a regular shut down when it is stopped. It then performs transactions. As the entire EBS volumes remain present, it is possible to start the instance anytime again when you want. The best thing is when the instance remains in the stopped state, users don’t need to pay for that particular time.
Upon termination, the instance performs a regular shutdown. After this, the Amazon EBS volumes start deleting. You can stop them from deleting simply by setting the “Delete on Termination” to false. Because the instance gets deleted, it is not possible to run it again in the future.

35. Your company’s branch offices are all over the world, they use a software with a multi-regional deployment on AWS, they use MySQL 5.6 for data persistence.
The task is to run an hourly batch process and read data from every region to compute cross-regional reports which will be distributed to all the branches. This should be done in the shortest time possible. How will you build the DB architecture in order to meet the requirements?
Explanation: For this we will take an RDS instance as a master, because it will manage our database for us and since we have to read from every region, we’ll put a read replica of this instance in every region where the data has to be read from. Option C is not correct since putting a read replica would be more efficient than putting a snapshot, a read replica can be promoted if needed to an independent DB instance, but with a Db snapshot it becomes mandatory to launch a separate DB Instance.
