Migration from a physical server on-premises to cloud server

1) Migration from a physical server on-premises to cloud server. Details- Right now, we have a box running 4 virtual machines under ESXi. One runs a Windows 2008 server with FoxPro Database and the other 3 run Windows 10Pro that we work from. The physical server is a Dell T330 with 64GB RAM, Intel Xeon E3-1220 v5 @3.0GHz, and 4 x 400GB SSDs configured in a hardware RAID producing 200GB, of which 85GB are in use. The files are mostly in 3 categories: - Database (3+ GB, shared access with multiple users making frequent changes concurrently to multiple files, high-speed access required for concurrency) - Images (11+ GB of which over half is archival. Mostly read-only access, except for original creation. Accessed occasionally, one at a time. High-speed access required only when searching or making bulk modifications. ) - Word-processing files and spreadsheets (20+ GB of which most is archival. Accessed by individual users who would each typically have 1 to 10 files open at a time. Disk access is only needed for opening each file, closing it, and periodic backup in the background.) The most important points for a service are: - Migrate to a Cloud based server/service. - Lean as possible, with a shared resources server to reduce overhead cost if possible - Security and redundancy is important 2) (Future project) Need to replace current Foxpro based custom application to SaaS based or cloud based custom inventory solution Details- We currently use FoxPro programs for virtually every aspect of the business: - Bookkeeping (*plan to replace with Quickbooks) - Processing leads and quotes* - Customer and supplier contact information* - Invoicing* (this could be done in the software and exported to QB, or done in QB based on exported data) - Tracking payables and receivables* - Purchase orders* - Database of product information - Cross referencing products to a database of pictures and brochures - CSV export of our product data to our websites and third party advertising Features we would like to have with this software: - Integrates with Quickbooks (marries our finance and inventory) - CRM information for products - Customizable to allow lots of different types of information on each product - Ability to easily see/cross-reference records in one database file to related to related data files, pictures and brochures - CSV export this data for upload on our websites and third party advertisers - We are open to suggestions for further improvement and efficiency so long as points above are satisfied.
