Direct Connect
AWS Direct Connect is a service that lets companies create a private, dedicated connection between their local offices or data centers and Amazon's cloud services. Think of it like having a private highway between two locations instead of using the public internet. Companies choose Direct Connect because it's more reliable, secure, and faster than regular internet connections. It's especially important for businesses that need to move large amounts of data to and from the cloud or require very stable connections for their applications.
