Reduce the cost of architecture
*Different types of Amazon EC2 families *Similar types of Amazon Ec2 family *Database on Amazon RDS |
*Compute Saving Plans
*Instance Saving Plans *Reserved instances for DB |
|
Disaster solution with EC2 instance
|
Create AMI of EC2
Copy to another region |
|
If you hibernate EC2 what happen with IPv4, IPv6 private and public?
|
Only public IPv4 addresses are assigned with new IP addresses. Private IPv4 and any IPv6 address are retained.
|
|
Security groups
*Inbound traffic *Outbound traffic |
*Inbound traffic - Blocked by default
*Outbound traffic - Allowed by default |
|
NACL
|
Network Access Control List is an optional layer of security.
|
|
EC2 in autoscaling group.
Database servers need to accept traffic from EC2 |
Ensure that the EC2 security group is placed as the source for the incoming rules in the database server security groups.

UD: Bootstrat script
Metadata: data about EC2 intances |

ENI
ENA EFA |
ENI: Possible a separate network
ENA: Speed between 10 to 100 Gbps --ena-support EFA: High Performance Computing (HCP) Machine learning applications or OS-bypass. |
|
EFA Limitations
|
*No supported on Windows instances
*Must be a member of security group that allows inbound and outbound traffic to and from security group itself. |

Placement Groups
|
Cluster: Not multiple AZ, Low network latency, high network throughput.
Spread: Multi AZ, individual critical EC2 instances. In different racks. Different types and size of instances. Partition: Multi Az, Multiple EC2 instances, HDFS, HBase and Cassandra. Similar types and size of instances. |
|
If you want a high-performance networking for their VPCs to operated based on SLAs. What do you suggest to accomplish?
|
A cluster placement group is appropriate for this use case because of a higher per-flow throghput limit of up to 10 Gbps except for the traffic over AWS Direct Connect to on.premise resource.
You can migrate an instance from one placement group to another but cannot merge placement groups. |
