The state of serverless computing and occasion streaming in 2024

The mix of occasion streaming and serverless computing usually leads to a cheap resolution for dealing with streaming information that considerably reduces the complexity of infrastructure administration and upkeep. This synergy permits builders to focus extra on software logic and fewer on core operational issues, leading to quicker growth.

Not way back, serverless occasion streaming meant utilizing an occasion streaming platform and stream processing engine (managed by a vendor or internally), supplemented by Operate-as-a-Service (FaaS) know-how the place applicable (akin to with short-lived and stateless) overheads. the job). It’s maybe beneficiant to name such a setup “serverless” contemplating that FaaS is the one serverless element.

Nonetheless, as a result of advances in serverless applied sciences, we not rely completely on FaaS. Different options, akin to serverless container-as-a-service (CaaS) instruments, are more and more getting used as the idea for occasion streaming use circumstances.

The present state of serverless computing

Serverless computing is on an upward trajectory. In accordance with Datadog’s 2023 State of Serverless report, all main cloud suppliers are seeing heavy adoption of serverless companies:

“Over the previous 12 months, serverless adoption has elevated by organizations operating in Azure and Google Cloud by 6% and seven%, respectively, and AWS has seen a 3% progress price. “Greater than 70% of AWS prospects and 60% of Google Cloud prospects at present use a number of serverless options, adopted by Azure at 49%.”
– Serverless State, Datadog, 2023

The rising reputation of serverless is comprehensible. Many organizations spanning each business are adopting serverless computing, enticed by the promise of value effectivity, on-demand scalability, decreased operational overhead, and quicker time to market.

Serverless adoption can be being fueled by the emergence of a various ecosystem of instruments. Along with FaaS (akin to AWS Lambda, Microsoft Azure Capabilities, and Google Cloud Capabilities), the serverless panorama has expanded to incorporate a wider vary of companies and capabilities, together with:

  • Serverless software platforms, akin to Netlify and Vercel.
  • Serverless databases akin to MongoDB Atlas, FaunaDB, and InfluxDB Cloud.
  • Serverless API administration platforms, together with AWS API Gateway and Azure API Administration.
  • Serverless frameworks like Zappa, Serverless Framework, Claudia.js, and Ruby on Jets.
  • Serverless CaaS options, for instance, AWS Fargate and Knative.

Serverless Strategy: FaaS vs. CaaS

Amongst FaaS options, serverless CaaS is quickly rising in significance. Datadog’s 2022 State of Serverless report exhibits that in 2022, Google Cloud Run was the quickest rising strategy to deploy serverless purposes in Google Cloud. The 2023 report signifies that serverless CaaS adoption has continued to extend throughout all main cloud suppliers.

The emergence of serverless CaaS is no surprise, because it supplies extra flexibility and eliminates a number of the inefficiencies of FaaS:

These variations between FaaS and CaaS are notably essential within the context of occasion streaming purposes. General, the CaaS mannequin is a extra dependable, versatile and appropriate strategy for dealing with high-frequency information flows.

The present state of the move of occasions

Occasion streaming (or information streaming) has change into an integral a part of trendy architectures, enabling organizations to gather, course of, retailer, and analyze information in actual time. Per Confluent’s “2023 Information Stream Report” Information move is excessive on the IT funding agenda:

“89% of respondents say investments in information move are essential, whereas 44% cite it as a high strategic precedence.”
— Information Stream Report, Confluent, 2023

The Confluent report notes that adopting information move applied sciences results in constructive enterprise outcomes, akin to elevated effectivity and profitability, improved responsiveness, enhanced buyer expertise, and quicker operational decision-making.

Organizations trying to embrace information move have loads of options to select from. As a consequence of its confirmed reliability, scalability, excessive efficiency, and wealthy ecosystem, Apache Kafka is normally the primary title that involves thoughts. However it isn’t the one choice. Different notable occasion streaming platforms embrace Amazon Kinesis, Google Cloud Pub/Sub, Apache Pulsar, and Azure Occasion Hubs. If you happen to’re involved in seeing how Kafka compares to a few of these options, try our comparisons of Kafka vs. Pulsar, Kafka vs. Redpanda, and Kafka vs. Kinesis.

Occasion streaming platforms complement a wide range of stream processing applied sciences, akin to Apache Flink, Apache Storm, Apache Samza, Apache Beam, Kafka Streams, ksqlDB, and Faust, every with their very own strengths. For instance, Beam supplies a single, unified API for dealing with each batch and streaming information, whereas ksqlDB simplifies the method of growing streaming purposes that rely solely on SQL queries.

There isn’t any doubt that occasion streaming is right here to remain and continues to develop in significance. Nonetheless, it may be troublesome to deal with the info move. A lot of the streaming applied sciences accessible at the moment are troublesome to make use of, and managing a streaming infrastructure at house shouldn’t be for the faint of coronary heart or these on a restricted price range. For instance, I touched on the various challenges of internet hosting and managing Kafka in a earlier article; Learn it to search out out what’s concerned.

The intersection between serverless streaming and occasions

In 2019, Neil Avery (previously a technologist within the CTO workplace at Confluent) printed a weblog submit analyzing the connection between occasion streaming and serverless computing. Neil’s submit discusses how FaaS suits into occasion streaming. The give attention to FaaS is smart, contemplating that FaaS was on the time the dominant type of serverless computing. Neil’s article is an effective learn, because it explains how FaaS can be utilized to enrich occasion streaming, in addition to its limitations, akin to chilly begin and lack of suitability for stateful stream processing.

Quick ahead to 2023. As a consequence of current technical advances, there’s a higher and tighter synergy between serverless and occasion streaming, far past FaaS. Listed here are some rising instruments and tendencies that mix serverless computing (aside from FaaS) and occasion streaming.

Serverless stream processing

Conventional stream processing usually entails an structure with many transferring elements that handle the distributed infrastructure and makes use of a fancy stream processing engine. For instance, Apache Spark, one of the crucial widespread processing engines, is troublesome to deploy, handle, tune, and debug (learn extra in regards to the good, the unhealthy, and the ugly of utilizing Spark). Implementing a dependable and scalable stream processing functionality can take between a number of days and some weeks, relying on the use case. Furthermore, you additionally must take care of fixed monitoring, upkeep and enchancment. You might also want a devoted workforce to deal with these overheads. Typically, standard move processing is troublesome, costly and time-consuming.

In distinction, serverless streaming processing eliminates the effort of managing advanced structure and underlying infrastructure. It is usually less expensive, as you solely pay for the assets you utilize. Naturally, serverless streaming processing options are beginning to emerge. One instance is Spark on Google Cloud. Google claims that that is the business’s first serverless Spark launch, which fully removes handbook infrastructure provisioning and tuning.

You talked about that CaaS is on the rise as a serverless strategy. Typically, serverless CaaS stream processing options have the next traits:

  • Low, predictable latency, with minimal processing delay.
  • Excessive throughput (as much as 1000’s or thousands and thousands of occasions per second).
  • Appropriate for each stateless and stateful processing workloads.
  • Appropriate for real-time information processing, in addition to batch processing.
  • Finest fitted to long-running, computationally intensive operations or operations with variable or unpredictable workloads.
  • Able to dealing with a number of information processing duties concurrently (concurrency).
  • You haven’t any server infrastructure to provision, preserve, or scale.

Bytewax is one instance of a stream processing know-how that may be leveraged utilizing a serverless CaaS mannequin. Bytewax is an open supply Python library and distributed stream processing engine for constructing streaming information pipelines. Amongst different choices, you possibly can run Bytewax information flows utilizing containers. This implies which you could, for instance, run Bytewax information flows on Amazon Elastic Kubernetes Service (EKS) or Amazon Elastic Container Service (ECS). Then you possibly can deploy these containers on AWS Fargate, Amazon’s serverless compute engine. This fashion, you may profit from serverless streaming processing with out having to provision, configure, or scale clusters of servers for containers.

Quix Streams is one other open supply Python stream processing library that removes the complexities of growing streaming purposes and processing real-time information. Being cloud native, it may be deployed on any Kubernetes cluster. It can be paired with Quix Cloud, which falls into the serverless CaaS class. Below the hood, Quix Cloud is a totally managed platform that makes use of Kafka, Docker, Git, containerized microservices, and a serverless compute setting to host streaming purposes. The aim is to allow builders to construct, deploy, and monitor purposes whereas eliminating the operational overhead of configuring, managing, and scaling containers and infrastructure.

For instance, CKDelta, an AI software program firm, makes use of Quix’s serverless streaming processing capabilities. CKDelta makes use of Quix to ship an occasion streaming software that makes use of machine studying to course of 40GB of Wi-Fi information per day from 180 underground practice stations in Singapore. Particularly, the appliance continuously collects high-throughput information and performs predictive analytics to foretell crowd density at practice stations.

If you happen to’re involved in different kinds of serverless occasion streaming apps you possibly can construct with Quix, check out these interactive templates.

Serverless message brokers

Past serverless stream processing, serverless message brokers are beginning to emerge. One instance is Amazon MSK Serverless, which is a brand new cluster sort for Amazon MSK. Whereas common MSK requires handbook setup and administration of Kafka clusters and expenses for accessible capability (no matter utilization), Serverless MSK robotically manages and scales the Kafka infrastructure primarily based on demand, charging for precise utilization.

Apache EventMesh is one other instance of a serverless event-driven middleware. EventMesh was created at WeBank, and is now a top-level mission on the Apache Software program Basis. Though EventMesh remains to be in its infancy, it already has practically 1,500 stars and practically 600 forks on GitHub, which is an encouraging signal. It will likely be attention-grabbing to see how EventMesh develops and if comparable initiatives emerge.


Occasion streaming has change into a mainstay of recent software program architectures. In the meantime, serverless computing has made spectacular progress over the previous few years; Gone are the times when FaaS was the one expression of serverless.

Given how troublesome it’s to take care of occasion streams and that serverless computing tremendously simplifies the method of extracting worth from streaming information, it isn’t stunning to see serverless occasion streaming options rising (or being adopted by enterprises). Such instruments typically include a user-friendly pricing mannequin (you solely pay for what you utilize), and allow corporations to gather and course of information streams in real-time with out having to consider underlying infrastructure and capability planning.

In the present day’s rising development is the mixture of serverless CaaS and streaming processing. Serverless CaaS combines the scalability and suppleness of containerization with the simplicity and cost-effectiveness of serverless architectures. It is a strong basis for dealing with high-volume, high-frequency dynamic information streams, so I am trying ahead to seeing extra contenders on this area.
