You have an application that you need to deploy to Google Cloud. The application communicates via TCP and performs read and write operations on the filesystem. This application does not support horizontal scaling, meaning it cannot be distributed across multiple instances to handle increased traffic. The application requires exclusive control over the filesystem data to prevent data corruption due to concurrent access. While the business can tolerate some downtime during incidents, the application needs to be operational 24/7 to support ongoing business activities. How should you design the architecture for this application on Google Cloud?
