About project

The application that we developed in this project is a fitness lesson management system. There are two user roles in the system: the instructor and the student. The instructor can register the lesson, and the student can participate in the lessson and send tips to the instructors via this system.

The system consists of an Android app, an iOS app, and an admin page. Here are some of the system’s main features:
-　Create lesson, join lesson
-　Search lesson, search instructor
-　Review/rate lesson
-　Share lesson
-　Send tips to instructor (student)
-　Withdraw tips to bank account (instructor)

Challenges

The operation of this application raises certain technical requirements.

Since this application has payment functions, security is put on top priority. The system must be restricted from unauthorized accesss and cyber-attacks. The system must have good load capacity in case the number of concurrent users increases. The system needs to store all users’ necessary data such as photos, lessons’ images, while maintaining high access speed and prevent data loss.

Despite the requirements, the operation cost still needs to be at a reasonable level. We evaluated many server options, including physical server purchase and server renting services from various providers. We could not balance all elements until we chose AWS as the solution for this project.

Solutions

In recent years, Kaopiz has switched our business strategy. We now focus the most on every project’s customer satisfaction. Therefore, we are introducing AWS into many more projects. The experienced (especially in AWS solutions) infrastructure engineers at Kaopiz designed a structure that complies all requirements provided.
1.　Amazon Elastic Compute Cloud (Amazon EC2) was used to run web server and API server.
2.　We also used Amazon Virtual Private Cloud (Amazon VPC) which lauches and isolates AWS resources in a virtual network so as to enhance security, prevent unauthorized access.
3.　In order to prevent the system from being overload in case the system has high level of active access, we combined Auto Scaling to the　infrastructure design.
4.　We incoporated Amazon Simple Storage Service (Amazon S3) and Amazon Relational Database Service (RDS) for their high performance and quick recovery after unexpected incidents.
5.　Amazon CloudWatch helps us watch and follow how resources’ usage and alerts when there are any trouble with the system.

Benefits

Compared to other cloud services, carrying out a project on AWS helped us reduce significantly the number of man-hours and costs related to configuration and server management. We were thus be able to quickly proceed with infrastructure construction.

Since the start of its operation, the system has been stable and have not had any downtime. Since AWS provides an advantageous environment for developing and operating applications, our problems are thoroughly solved by using services from AWS.

System administrators can easily control, summarize and analyze data of resources launched on AWS. The application components’ storage, the infrastructure (RAM, disc, etc.) and used services, all are closely monitored.

Other than that, with the help of AWS services, our application is easier to operate, has stronger security, and delivers better user experience.
