An organization is deploying a web application on a scalable cloud infrastructure. They need to ensure all communications between the web browsers of their clients and the servers are encrypted. Which approach would be the MOST appropriate to guarantee encryption of the data being transmitted over the internet?
Incorporate a key management service to generate encryption keys used to manually encrypt data before transmission over the internet.
Provision, manage, and automate the renewal of SSL/TLS certificates for deploying on load balancers and content delivery networks.
Implement custom encryption in the application code to handle encryption before sending data over the network.
Utilize automated server-side encryption in the storage layer to secure data before it leaves the cloud environment.
