aws iot car connected solution

First of all sorry for my bad english! I'm planning to make my own project called "Car connected iot device" I'm planning to use AWS IoT service to combine all the services that I want to use e.g. Amazon dynamoDB, Amazon S3 and or so. The whole schematic of my project is seen below 1. Data logger Using Elm327 or STN1110 OBD2 auto detect protocol module with mpu6050 GYRO sensor and SD card module(for logging the data e.g. rpm, engine coolant temp, etc) I already have device to iot starter kit made of Wiznet (you can find it on github) to connect with AWS iot server. However, it would be more proper to use ESP32 board with bg96 module to connect to AWS iot server ,since ESP32 board has dual core processor so that I can handle the process of dealing the Car receiving data seperated from the lte [login to view URL] module processing. 2. Cloud backend infra Actually I have done receiving data from car and calculate specific data. Step2 would be my major requestion. I'm not familiar with wirless connection e.g. bluetooth,wifi,lte also I'm not major of this kind of sector. It would be good to give me a detailed explanation about aws iot cloud service deal with my own project. Actually I've found quite similar solution compared to my project, called "AWS connected car solution" - link -> [login to view URL] [login to view URL] For this step, It's hard to pick which board should I use and what would be appropriate to organize total hardware of my project 3. user interface If the previous step is totally complete , I'm gladly willing to pay additional fee for this process.
