What is the best way to monitor the performance of each integration in a microservice-oriented architecture using Cloud Trace?

Azgomi is a popular community application that facilitates communication between people in close proximity. It is used for event planning, organizing sporting events, and connecting businesses with their local communities. Although it launched recently in a few neighborhoods in Dallas, it is rapidly expanding into a global phenomenon. The company's venture capital investors are looking for rapid growth and expansion into new regions, offering the same experience to users, regardless of their location.

Azgomi wants to expand its service to new regions, with updated functionality to better serve its global customers. They plan to hire and train a new team to support these regions in their respective time zones. It is essential that the application scales smoothly and provides clear uptime data, and that they analyze and respond to any issues that occur. The existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. The application runs on Compute Engine virtual machine instances hosted in GCP. State is stored in a single instance MySQL database in GCP. Release cycles include development freezes to allow for QA testing. The application has no logging. Applications are manually deployed by infrastructure engineers during periods of slow traffic on weekday evenings. There are basic indicators of uptime, and alerts are frequently fired when the APIs are unresponsive.

Azgomi's investors want to expand its footprint and support the increase in demand they are seeing. They require the following:

• Expand availability of the application to new regions.

• Support 10x as many concurrent users.

• 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 (for example, GDPR).

• Reduce infrastructure management time and cost.

• Adopt Google-recommended practices for cloud computing.

○ Develop standardized workflows and processes around application lifecycle management.

○ Define service level indicators (SLIs) and service level objectives (SLOs).

The technical requirements for Azgomi include:

• Providing secure communications between the on-premises data center and cloud-hosted applications and infrastructure.

• The application must provide usage metrics and monitoring.

• APIs require authentication and authorization.

• Implement faster and more accurate validation of new features.

• Logging and performance metrics must provide actionable information to be able to provide debugging information and alerts.

• Must scale to meet user demand.

What steps can Azgomi take to revamp their architecture in order to accommodate a significant surge in user traffic?

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 public API must be created that can authenticate, enforce quotas, and report metrics for API callers.

What is the recommended tool to use for finishing this architecture?
