Upon evaluating TerramEarth's business requirements to minimize downtime, it was determined that a substantial amount of time-saving could be achieved by decreasing customers' wait time for parts. Consequently, the decision has been made to concentrate efforts on reducing the aggregate reporting time of three weeks. What changes to the company's processes would you suggest?

Your company has a service that needs to run on a fleet of identical instances and scales according to traffic patterns. You are tasked with setting up a Managed Instance Group (MIG) on Google Cloud Platform. The instances are created from an instance template and a startup script, which fetches the latest version of the application code from a Cloud Storage bucket every time an instance starts. However, your company wants to avoid any potential downtime when deploying updates to the application. Which strategy should you recommend?

Which Google Database should they use?

As a cloud architect, you set up the optimal combination of CPU and memory resources for nodes in a Kubernetes cluster. You want to be notified whenever CPU utilization exceeds 80% for 5 minutes or when memory utilization exceeds 90% for 1 minute. What do you need to specify to receive such notifications?

Your customer is planning to store a large amount of log data in Google Cloud. The customer has the following requirements:

• the data must be easily searchable and filterable
