关于客户

Heluna is a cloud-based anti-spam service provider that has been in operation since 2004. The company offers a unique SaaS-based solution that integrates seamlessly with existing email infrastructures to filter out spam and deliver clean messages efficiently. Heluna's service is trusted by its customers to filter out approximately 78% of all email messages, which are typically spam, while ensuring timely delivery of legitimate emails. The system benefits from years of experience and automated learning, allowing it to adapt and improve its spam detection capabilities continuously. Heluna's commitment to providing a reliable and effective anti-spam solution has made it a trusted partner for businesses seeking to protect their email communications from spam and other malicious content.

挑战

Heluna faced a significant challenge in scaling its anti-spam service to meet the growing demand for processing millions of email messages daily. The existing platform, which relied on legacy technologies like Sendmail, Perl, and C, was unable to scale horizontally to accommodate the increasing volume of emails. This lack of scalability threatened the reliability and performance of Heluna's service, prompting the need for a more robust and scalable solution. The founder and chief architect, Mark Beeson, recognized that the current architecture was untenable for long-term growth and sought to improve the system's scalability, performance, and operational visibility.

解决方案

To address the scalability challenges, Heluna adopted the Typesafe Platform, which includes Scala, Akka, and Play Framework. Scala, a general-purpose programming language, was chosen for its ability to distribute computation across multicore servers and datacenters, making it ideal for modern cloud-computing workloads. Akka, a toolkit for building concurrent and distributed applications, simplified the concurrency problem by providing a higher level of abstraction through its Actor-based model. This allowed developers to focus on business logic rather than low-level tasks. The Play Framework, with its lightweight and stateless architecture, ensured minimal resource consumption for highly scalable applications. The new architecture consisted of three main components: Mail Accepter, Mail Filtering, and Mail Delivery. The Mail Accepter processed incoming emails using a Scala application, while the Mail Filtering component utilized Akka actors for high-level filtering and anti-spam systems. Finally, the Mail Delivery component used Akka actors to send emails to client systems. This flexible architecture allowed Heluna to scale its operations easily, leveraging Amazon's EC2 infrastructure for additional nodes as needed.
