Everyone, please provide your suggestions.
Does anyone have experience with hybrid cloud?

You can check the recommended resource configuration for deployment nodes on the official website.

After deployment, make sure to conduct compatibility and performance verification tests for the business. Generally, these tasks need to be done in advance when launching new business in a new environment.

If it’s on Alibaba Cloud: It is recommended to choose local NVME storage for TiKV, with at least 3 nodes. Unless you know how to use labels, you can deploy it on a bare metal host; TiDB and PD do not have high disk requirements.

Hybrid Cloud: You need to consider network costs, with latency not less than 100ms, which can be quite resource-intensive for the network; if you are setting up a primary-backup configuration, there are no significant requirements.

How do you handle your hot and cold data?

I/O optimization is what performance

I haven’t seen such a large local SSD on Alibaba Cloud. The largest one is just 1.8T.

The configuration is pretty good.

The official documentation has standard deployment configuration instructions:

I just thought of a key point: when deploying virtual machines, ensure that the virtual machines are not on the same physical machine. If the hardware fails, everything will be affected.

You can pay attention to storage costs. I haven’t calculated the price of Alibaba Cloud ESSD compared to adding disks directly on bare metal (on another cloud, once it exceeds 3T or 4T, the price of cloud disks directly surpasses that of the machine itself :joy:).

This budget is quite high, isn’t it?

What was the previous cluster configuration? Please share it as well. Without a comparison, we can’t tell if there has been any cost reduction.

This price… 5370.77*12=64,449.24

Cloud server storage is relatively expensive.

Alibaba Cloud has just experienced a large-scale service disruption.
