Q

AWS Fargate

A
  • Fargate allocates the right amount of compute, eliminating the need to choose instances and scale cluster capacity.
  • You only pay for the resources required to run your containers, so there is no over-provisioning and paying for additional servers.
  • Works with EKS and ECS.

Q

EC2 vs. Fargate

A
  • EC2- instances will assist in launching containers, more management needed

  • a cost-effective, monthly plan.
23
Q

Network ACL

A
  • Firewall that controls traffic between subnets in a VPC,

- stateless

24
Q

Security Groups

  • firewall that is located near VM that controls access in and out of VM,
  • stateful
25
Q

Route 53

A
  • connects user requests to infrastructure running in AWS such as, Amazon EC2 instances, Elastic Load Balancing load balancers, or Amazon S3 buckets
  • can also be used to route users to infrastructure outside of AWS.
26
Q

Route 53- Routing Policies

A
  • Simple Routing
  • Weighted
  • Geolocation
  • Latency
  • Failover
  • Multivalue answer
27
Q

Route 53- Simple Routing

A

routing traffic to just one resource, such as a web server

28
Q

Route 53- Weighted

A

When you have multiple resources that do the same job, and you want to specify the proportion of traffic that goes to each resource. Ex. 2 or more EC2 instances

29
Q

Route 53- Geolocation

A

Route traffic based on the location of your users

30
Q

Route 53- Latency

A

When you have resources in multiple AWS regions and want to route traffic to the region that provides the best latency

31
Q

Route 53- Failover

A

Route traffic to a resource when the resource is healthy, or to a different resource when the first resource is unhealthy

32
Q

Route 53- Multivalue Answer

A

Route 53 will respond to DNS queries with up to 8 healthy records selected at random

33
Q

CloudFront

A

CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the request is routed to the edge location that provides the lowest latency (time delay), so that content is delivered with the best possible performance.

34
Q

CloudFront Key Features

A
  • Caching Content

- Edge Locations

35
