DigitalOcean is a platform that offers its customers an easy way to deploy their solutions on the cloud. Why easy? Because most of the services are configured for you by default and you only have to use the online portal to add your data—DigitalOcean also supports a command-line interface that can be used to automate jobs. Storage services, domain servers etc. are all configured as a part of the platform.
I have a friend who works with a client powering an advertisement system on DigitalOcean with millions of requests being served each day! So the platform has a good potential, and as a beginner you would not worry about configuring a virtual network, mapping system configurations, etc. you will just need to worry about how to get your application’s source code on the cloud.
Now, for a beginner, it can be a good choice and can not be a good choice and it depends. It is a good choice, because it has a clear UX that can help you just get started. No clutter and clear pricing models help you understand your commitment with DigitalOcean.
It is not good for beginners, because most of the services require some advanced concepts to be known, for example Droplets created are basic Linux VMs, so you need to know how that works, also Kubernetes engine requires prior knowledge of Kubernetes.
If you are a beginner in software development, then I would recommend exploring free credits and trying out the platform before working out the production environment on DigitalOcean.
