A Network Engineer is provisioning a subnet for a load balancer that will sit in front of a fleet of application servers in a private subnet. There is limited IP space left in the VPC CIDR. The application has few users now but is expected to grow quickly to millions of users.
What design will use the LEAST amount of IP space, while allowing for this growth?
A company has multiple AWS accounts. Each account contains one or more VPCs. A new security guideline requires the inspection of all traffic between VPCs.
The company has deployed a transit gateway that provides connectivity between all VPCs. The company also has deployed a shared services VPC with Amazon EC2 instances that include IDS services for stateful inspection. The EC2 instances are deployed across three Availability Zones. The company has set up VPC associations and routing on the transit gateway. The company has migrated a few test VPCs to the new solution for traffic inspection.
Soon after the configuration of routing, the company receives reports of intermittent connections for traffic that crosses Availability Zones.
What should a network engineer do to resolve this issue?
A company is planning to use an AWS Transit Gateway hub and spoke architecture to migrate to AWS. The current on-premises multi-protocol label switching (MPLS) network has strict controls that enforce network segmentation by using MPLS VPNs. The company has provisioned two 10 Gbps AWS Direct Connect connections to provide resilient, high-speed, low-latency connectivity to AWS.
A security engineer needs to apply the concept of network segmentation to the AWS environment to ensure that virtual routing and forwarding (VRF) is logically separated for each of the company's software development environments. The number of MPLS VPNs will increase in the future. On-premises MPLS VPNs will have overlapping address space. The company's AWS network design must support overlapping address space for the VPNs.
Which solution will meet these requirements with the LEAST operational overhead?
