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. [...]

EBS – SSD vs HDD

2024-01-25T07:23:57+00:00

On a given volume configuration, certain I/O characteristics drive the performance behavior for your EBS volumes. SSD-backed volumes, such as General Purpose SSD (gp2) and Provisioned IOPS SSD (io1,io2), deliver consistent performance whether an I/O operation is random or sequential. HDD-backed volumes like Throughput Optimized HDD (st1) and Cold HDD (sc1) deliver optimal performance only when I/O operations are large and sequential. In the exam, always consider the difference between SSD and HDD as shown on the table below. This will allow you to easily eliminate specific EBS-types in the options which are not SSD or not HDD, depending on [...]

Security Group vs NACL

2024-01-25T05:34:33+00:00

Security Group Network Access Control List Acts as a firewall for associated Amazon EC2 instances. Acts as a firewall for associated subnets. Controls both inbound and outbound traffic at the instance level. Controls both inbound and outbound traffic at the subnet level. You can secure your VPC instances using only security groups. Network ACLs are an additional layer of defense. Supports allow rules only. Supports allow rules and deny rules. Stateful (Return traffic is automatically allowed, regardless of any rules). Stateless (Return traffic must be explicitly allowed by rules). Evaluates all rules before deciding whether to allow traffic. Evaluates rules [...]

AWS CloudTrail vs Amazon CloudWatch

2023-06-27T01:45:43+00:00

AWS CloudTrail vs Amazon CloudWatch Cheat Sheet CloudWatch is a monitoring service for AWS resources and applications. CloudTrail is a web service that records API activity in your AWS account. They are both useful monitoring tools in AWS. By default, CloudWatch offers free basic monitoring for your resources, such as EC2 instances, EBS volumes, and RDS DB instances. CloudTrail is also enabled by default when you create your AWS account. With CloudWatch, you can collect and track metrics, collect and monitor log files, and set alarms.
