Is serverless just a stopover for event-driven architecture?

Click for: original source

I recently reviewed the State of Cloud Native Development report by SlashData supported by the Cloud Native Computing Foundation that shows a decline in cloud native technologies from the first quarter of 2020 to the first quarter of 2021. By Mark Hinkle.

This makes me think that the hype around serverless has died down, though that doesn’t mean that serverless isn’t going to be around for a long time.

Perhaps as CNCF CTO Chris Aniszczyk told SDX Central, “The trend reflects growing concern that serverless technologies lack the flexibility needed for widespread adoption and a reluctance among organizations to commit to specific technologies or providers.”

The article main content then focus on:

  • Serverless isn’t a failure, it’s an implementation detail
  • Event-driven architecture in cloud native computing
  • Event-driven data syncs and workflows

We are moving toward an event- and data-driven future, where the ability to act in real time on data is becoming a requirement for doing digital business. The first part of the equation requires data streaming technologies that are similar to AWS Kinesis but not specific to a single vendor. Apache Kafka and Apache Pulsar fit the bill as open source, cloud-agnostic ways to put data in motion. Then the next step is to adopt publish-subscribe communication across microservices rather than making REST calls to APIs.

The future of the cloud is not necessarily all-in-one vendors. We’ve been down that road before where users have sacrificed the freedom to choose the best-in-class solution for the convenience of a preassembled stack from one vendor. The future is composable systems of best-of-breed technologies rather than stacks from a single vendor. The new design pattern for cloud native users is composable infrastructure and consequently composable applications that are an amalgamation of various vendors and connected via event streams that are used to create automated workflows.
