The blog post details the creation of a chatbot using a serverless architecture, specifically on the Viber platform, highlighting the benefits of serverless for handling sporadic and cyclic use. The author chose Viber due to its reliable communication features and simple, well-documented REST API. Using Azure Functions, the chatbot was developed in C# without a .NET SDK for Viber, necessitating direct REST API interactions via RestSharp. The chatbot can perform basic tasks like greeting users, providing metrics, and making Twitter recommendations by processing messages through simple if/else statements. Couchbase is used for logging and querying incoming messages, leveraging its compatibility with Viber's JSON-based API and ease of scaling. The post concludes by encouraging readers to explore various possibilities with chatbots and shares enthusiasm for potential future developments in this area.
