# The Technical Data Guidance

## EN

The  following key words about network are the technologies that I had study and used. And now I'm studying the fourth generation of web application technologies and the Firebase dynamic database, after I  fully understand  and can use these technologies, I will sort out them again

### The keywords for third generation web platform

#### **Compute Engine:** Google Cloud based on United States(us-west2-a)

> Supplement: GCP is for formal plan. After I test Alicloud, Tencent Cloud, Amazon Cloud, I found GCP is the best choice.

#### **IP:** Google Anycast IP + Premium Host IP

| Category         | **Premium**                                                                                            | Standard                                                                                                    |
| ---------------- | ------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------- |
| Network          | High performance routing                                                                               | Lower performance network                                                                                   |
| Network Services | Network services such as Cloud Load Balancing are global (single VIP for backends in multiple regions) | Network services such as Cloud Load Balancing are regional (one VIP per region)                             |
| Service Level    | High performance and reliability, Low latency, Global SLA                                              | Performance and availability comparable to other public cloud providers (lower than premium), no Global SLA |
| Use Case         | Performance, reliability, global footprint and user experience are your main considerations            | Cost is your main consideration, and you’re willing to trade-off some network performance                   |
