Pros
Pro Good API
DigitalOcean has an API for creating and destroying droplets and replicating droplet control panel functionality. The API is RESTful, uses oAuth, supports IPv6 and comes with an extensive documentation.
Pro Beginner-friendly
DigitalOcean has a control panel that's intuitive and easy to use, new servers (Droplets) can be spun up in under a minute and they offer stock "apps" (LAMP, RoR, Wordpress) that can be deployed instantly. There's also an extensive documentation for people new to VPS.
Cons
Con No DDoS protection
When Digital Ocean detects what they think may be a DoS attack, they will cut traffic to the droplet to avoid performance drops to neighbors etc. This means if your droplet comes under attack, or appears to be under attack, it will be disconnected from the network, effectively down.
