A hosting company is migrating to cloud-based solutions. Their customers share a physical firewall cluster, subdivided into individual logical firewalls for each customer. Projection data shows that the cloud service will soon deplete all the resources within the physical firewall. As a consultant, you must propose a scalable solution that continues to protect all the cloud customers while still securing the existing physical network.

In this scenario, which solution would you propose?

  1. Deploy a vSRX cluster in front of each customer’s servers while keeping the physical firewall cluster
  2. Deploy a software-defined networking solution
  3. Remove the physical firewall cluster and deploy vSRX clusters dedicated to each customer’s servers
  4. Replace the physical firewall cluster with a higher-performance firewall
