Autoscaling plan for IoTDB (e.g. on Azure)

**Is your feature request related to a problem? Please describe.**

At our company, we want to have most of our services as managed services. This makes maintenance very effective on our side as we do not have to employ more people to keep the infrastructure running. Currently this is a blocker for integrating IoTDB, as everything around this database would have to be managed and scaled manually.

**Describe the solution you'd like**

A part of the documentation, describing an example of how to set up IoTDB by using only auto-scaling modules of a cloud provider - for me Azure would be the best example.

**Describe alternatives you've considered**

The documentation already has something about a Hadoop Cluster, which I could find as managed solution on Azure, but I don't know if it's a good solution (price-vise) and if it will scale automatically with our demands.

**Additional context**

Any hint is also very welcome!

As I understand, integrating the storage as a managed storage would already be a huge improvement - like a storage abstraction which is compatible with Azure Storage.

For the IoTDB instance itself my first thought was to set up a VM scale set, which will add new VMs to a cluster as certain limits (e.g. in CPU usage) are reached. If this whole idea of mine is just not the right way, I'm thrilled to get your input.

Bắt đầu với tài liệu Hadoop Cluster hiện có và nghiên cứu các phương án thay thế do Azure quản lý, bao gồm VM scale sets và bộ nhớ lưu trữ được quản lý. Xác định liệu một triển khai IoTDB có autoscaling có khả thi hay không, và ghi lại một ví dụ cụ thể trên Azure, bao gồm phương án lưu trữ, hành vi scaling và các đánh đổi liên quan.
