Q7: Good practice for HA

Answer 2

HA can be achieved using multiple AZs within the VPC. webapps runs on public subnet and databases run on private subnets. Autoscaling Groups help to launch new instances and load balancer helps distribute load across multiple AZs

Question 3

Q9: SQS best practice

Answer 3

AWS recommends using multiple queues when doing prioritization, sqs by itself can not proivide logic , therefore it needs to be implemented at the application layer

Question 4

Q10: Route 53 routing policies

Answer 4

1- Simple Routing: This is the default routing policy, where traffic is routed to a single endpoint. It is useful for applications that have a single endpoint, such as a website or an API.

2- Weighted Routing: With this policy, traffic is routed to different endpoints based on the weight assigned to each endpoint. For example, if you have two endpoints and you assign a weight of 60 to one and 40 to the other, 60% of the traffic will be directed to the first endpoint, and 40% to the second.

3- Latency-based Routing: This policy routes traffic to the endpoint that has the lowest latency, based on the geographic location of the user. This is useful for applications that require fast response times, such as gaming or video streaming.

4- Geolocation Routing: With this policy, traffic is routed to different endpoints based on the geographic location of the user. For example, if you have endpoints in the US, Europe, and Asia, you can route traffic to the nearest endpoint based on the user’s location.

5-Failover Routing: This policy is used to route traffic to a secondary endpoint when the primary endpoint is unavailable. It is useful for applications that require high availability and need to switch to a backup endpoint in case of a failure.
