DigitalOcean vs AWS Lightsail vs Azure for a small financial analytics company?

Hello, Id like to ask some advice from people with experience in this area. Which would you choose for this use case: Im not an expert in hosting. I run a very small company focused on finance, accounting and business analytics.Thanks in advance for your help! I already have a working Python system for: Accounting/financial Data analytics ETL, EDA, etc Automated reports Financial analysis Right now everything runs from my personal OneDrive. That was fine during development, but now other companies are interested in using the same system, so I need proper cloud infrastructure. This is what we basically need. Separate each client's data securely Run Python pipelines Store data in a database Allow AI tools/agents to connect to the data and analyze it (chatgpt business allows to remotely connect via ssh) Keep infrastructure simple and inexpensive Be able to scale later I've been looking at DigitalOcean, AWS Lightsail and Azure. DigitalOcean looks simple and affordable. Lightsail caught my attention because it seems similarly simple but gives me a path into the AWS ecosystem. Azure looks powerful for data/AI, but maybe overkill at this stage. Which would you choose for this use case, and why?
