Dynamics 365 Finance / SCM Tier1 sandbox environments are heavily used by partners for development and building Dynamics 365 Finance / SCM applications. Microsoft-hosted Tier 1 environments were a great deal because we got well sized VMs with 28 GB RAM and 4 Cores plus SQL Server, Visual Studio and Dynamics 365 Finance pre-installed for a very small fixed price per month available 24/7. Now Microsoft recently announced that they will no longer include Microsoft-Hosted Tier1 Sandbox environments with the Dynamics 365 Financen / SCM license and we will no longer be able to purchase additional Tier1 sandbox Addons. The preferred solution is to use Cloud-Hosted environments instead.

Microsoft-Hosted vs. Cloud-Hosted
From a technical standpoint there is no difference between a Microsoft-Hosted or a Cloud-Hosted environment. Both solutions deploy a Windows Server VM in Azure. In both cases the deployment is managed via Lifecycle Service (LCS).

However, there are 3 major aspects to consider:
One big difference is the pricing model. Microsoft-Hosted environments (or Addons) come with a fixed (!) price per month while Cloud-Hosted environments deploy on an Azure subscription and therefore are billed like a classic IaaS (aka. virtual Machine in Azure). Make sure to calculate the costs (!) and turn of the environments if not needed.
Another difference is the ability to choose the sizing of the deployed environment. In contrast to Microsoft-Hosted Tier 1 environments, you are now free to choose a sizing that fits your needs e.g. more (or less) RAM, CPU, Premium SSD storage, etc.
Moreover, in contrast to Microsoft-Hosted environments, we now get an Admin account on our machines. It was understandable that Microsoft tried to lock down the cheap VMs to prevent the misusage with anything else then Dynamics 365. Since we own and pay the VM in a Cloud-Hosted environment its more than fair to have Admin access on the machine.
