DigitalOcean's commitment to simplifying cloud computing and providing an excellent experience for its customers is at the forefront of all it does, particularly in supporting startups and small businesses. The company uses Let's Encrypt, a Certificate Authority built by the Internet Security Research Group, to provide free, automated certificates for its customers. This integration has been expanded over time to include features such as wildcard domains, support for managed MongoDB connections, and automatic certificate renewal, which is done every four hours to ensure that certificates are renewed before they expire. The company's migration to using ECDSA keys instead of RSA with 2048-bit keys has also improved performance by reducing CPU usage by up to 30%. Additionally, DigitalOcean provides tutorials and a Marketplace app for customers who need Let's Encrypt certificates in their Docker containers.
