Latency Routing vs Geoproximity Routing vs Geolocation Routing

2023-04-10T03:27:57+00:00

  Latency Routing Geoproximity Routing Geolocation Routing Definition Lets Route 53 serve user requests from the AWS Region that provides the lowest latency. It does not, however, guarantee that users in the same geographic region will be served from the same location. Latency-based routing is based on latency measurements performed over a period of time, and the measurements reflect changes in network connectivity and routing. Lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources.  You can also optionally choose to route more traffic or less to a given resource [...]

EC2 Instance Health Check vs ELB Health Check vs Auto Scaling and Custom Health Check

2024-02-13T06:24:11+00:00

EC2 instance health check Elastic Load Balancer (ELB) health check Auto Scaling and Custom health checks Amazon EC2 performs automated checks on every running EC2 instance to identify hardware and software issues. Status checks are performed every minute and each returns a pass or a fail status.  If all checks pass, the overall status of the instance is OK.  If one or more checks fail, the overall status is impaired. Status checks are built into EC2, so they cannot be disabled or deleted. You can create or delete alarms that are triggered based on the result of the status checks. [...]

SNI Custom SSL vs Dedicated IP Custom SSL

2023-04-12T00:51:16+00:00

Server Name Indication (SNI) Custom SSL Dedicated IP Custom SSL Relies on the SNI extension of the TLS protocol, which allows multiple domains to serve SSL traffic over the same IP address. Offers the same level of security when using Dedicated IP Custom SSL. If you configure CloudFront to serve HTTPS requests using SNI, CloudFront associates your alternate domain name with an IP address for each edge location. The IP address to your domain name is determined during the SSL/TLS handshake negotiation, and isn't dedicated to your distribution. Some older browsers do not support SNI and will not be able [...]

Service Control Policies (SCP) vs IAM Policies

2023-04-12T00:38:41+00:00

Service Control Policies (SCP) IAM Policies SCPs are mainly used along with AWS Organizations organizational units (OUs). SCPs do not replace IAM Policies such that they do not provide actual permissions. To perform an action, you would still need to grant appropriate IAM Policy permissions. Even if a Principal is allowed to perform a certain action (granted through IAM Policies), an attached SCP will override that capability if it enforces a Deny on that action. SCP takes precedence over IAM Policies. SCPs can be applied to the root of an organization or to individual accounts in an OU. When you [...]
