An organization has multiple applications running in VPCs across multiple AWS accounts. The network engineer has deployed a central VPC with a pair of software VPN instances that run IPSec tunnels with dynamic routing to VGWs of all application VPCs. This central VPC is connected to on-premises resources via a Direct Connect connection using a private VIF. What additional configuration is required to enable the applications in VPCs to communicate with each other and access onpremises resources?
A company is building a hybrid PCI-DSS compliant application that runs in the us-west-2 Region and on-premises.

An organization is migrating its on-premises applications to AWS by using a lift-and-shift approach, taking advantage of managed AWS services wherever possible. The company must be able to edit the application code during the migration phase. One application is a traditional three-tier application, consisting of a web presentation tier, an application tier, and a database tier. The external calling client applications need their sessions to remain sticky to both the web and application nodes that they initially connect to.

Which load balancing solution would allow the web and application tiers to scale horizontally independent from one another other?

A.
Use an Application Load Balancer at the web tier and a Classic Load Balancer at the application tier. Set session stickiness on both, but update the application code to create an application-controlled cookie on the Classic Load Balancer.
