Question No. 1

A company runs a public-facing application that uses a Java-based web service via a

RESTful API in their on-premises data center. Use of the API is expected to double with a new

product launch. The business wants to migrate their application to Oracle Cloud Infrastructure

(OCI) to meet the scale and reliability requirements. In order to achieve this, they will divert only

40% of the traffic to the new Apache Tomcat web servers running on OCI and serve the

remaining 60% traffic through their on-premises infrastructure. Once the migration is complete

and application works fine, they will divert all traffic to OCI.

How can these requirements be met with the LEAST amount of effort?

AUse OCI Traffic management service with failover steering policy and distribute the traffic
between OCI and on premises infrastructure.

BUse OCI Traffic management service with Load Balancing steering policy and distribute the
traffic between OCI and on premises infrastructure.

CUse an OCI load Balancer and distribute the traffic between OCI and on premises
infrastructure.

DUse VPN connectivity between on premises Infrastructure and OCI and create routing tables
to distribute the traffic between them.

Show Answer

Correct Answer: B

Option A is incorrect because using OCI Traffic management service with failover steering policy will not distribute the traffic between OCI and on premises infrastructure.Failover steering policy will only route traffic to a secondary endpoint if the primary endpoint is unresponsive2. This is not suitable for a gradual migration scenario.

Option B is correct because using OCI Traffic management service with Load Balancing steering policy will distribute the traffic between OCI and on premises infrastructure based on a ratio or round robin algorithm2. This will allow you to control the percentage of traffic that goes to the new infrastructure in OCI and monitor the results.

Option C is incorrect because using an OCI load Balancer will not distribute the traffic between OCI and on premises infrastructure.A load balancer will only distribute the traffic among multiple compute instances within a single region in OCI2. This will not help you migrate from your on premises infrastructure.

Option D is incorrect because using VPN connectivity between on premises Infrastructure and OCI and creating routing tables to distribute the traffic between them will require more effort than using OCI Traffic management service.You will need to set up a VPN connection, configure routing rules, and monitor the network performance2. This will not be as simple and reliable as using a DNS-based solution.
