An API is being developed for use in Android and iOS apps.

What kind of API architecture would be suitable for an API that needs to support HTTPs, minimize bandwidth cost, and integrate easily with mobile apps?

Your application runs smoothly when tested on a local environment, but its performance significantly degrades when deployed on a Compute Engine instance. Your task is to identify the root cause of the issue.

What actions do you think are appropriate?

The organization you are working for manages an ecommerce site, and the application is deployed behind a global HTTP(S) load balancer. You are required to test a new product recommendation algorithm, and to determine the new algorithm's effect on sales in a randomized way, you plan to use A/B testing.

What is the recommended way to conduct testing for this feature?

The case study involves Azgomi, a community application used for event planning, organizing sporting events, and for businesses to connect with their local communities. It has recently launched in a few neighborhoods in Dallas and is rapidly growing into a global phenomenon. Its unique style of hyper-local community communication and business outreach is in demand around the world.

The executive statement is to take the local community services global, with the venture capital investors wanting to see rapid growth and the same great experience for new local and virtual communities that come online, whether their members are 10 or 10000 miles away from each other.

Azgomi wants to expand their existing service with updated functionality in new regions to better serve their global customers. They plan to hire and train a new team to support these regions in their time zones. They also need to ensure that the application scales smoothly and provides clear uptime data.

Azgomi's existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. They have limited experience in global-scale applications.

The business requirements are to expand the availability of the application to new regions, increase the number of concurrent users that can be supported, ensure a consistent experience for users when they travel to different regions, obtain user activity metrics to better understand how to monetize their product, ensure compliance with regulations in the new regions, reduce infrastructure management time and cost, and adopt the Google-recommended practices for cloud computing.

The technical requirements are that the application and backend must provide usage metrics and monitoring, APIs require strong authentication and authorization, logging must be increased, and data should be stored in a cloud analytics platform. They must move to serverless architecture to facilitate elastic scaling and provide authorized access to internal apps in a secure manner.

What is the most suitable method for Azgomi to store their application state to fulfill their business needs?

A stateless web application for a marquee is being developed for Google Cloud. It is expected that the incoming user traffic will be unpredictable, with some days having no traffic while other days will have large spikes. The application should be able to automatically scale up and down, while minimizing the cost associated with running the application.
