Couchbase Server and Couchbase Mobile can be effectively deployed using Amazon's AWS Free Tier program, which provides 12 months of free AWS access. This guide explains how to install the Couchbase AMI on Amazon EC2, allowing users to leverage Couchbase Server and Couchbase Sync Gateway software. It starts with creating a new AWS account and selecting the Basic (Free) support plan, followed by accessing the AWS Marketplace to choose the "Couchbase Server & Couchbase Sync Gateway Community Edition" AMI. Once selected, users configure the EC2 instance, create a key pair, and accept terms to launch the AMI on EC2. After launching, users can access the Couchbase web console via a specific URL and log in with credentials found in the EC2 Console. The blog concludes with a preview of the next steps involving the integration of Sync Gateway with Couchbase Server to enable data replication for a Couchbase Mobile application.
