Apache Kafka® is an open-source distributed event streaming platform used by 80% of Fortune 100 companies as well as thousands of small-to-midsize businesses (SMBs) for implementing high-performance data pipelines, streaming analytics, data integration, and mission-critical applications. Event streaming architecture is commonly used in robotic manufacturing, self-driving vehicle navigation, IoT network device monitoring, real-time shipping logistics, and millions of other forms of custom analytics for businesses and enterprises.
When implementing a Kafka-based event streaming architecture, IT teams face two major challenges: 1) building and maintaining the Apache Kafka infrastructure; and 2) adding custom code to implement event messaging across existing products, services, and operations. The scale of the event messaging system depends on the web/mobile traffic or device requirements. There are two common approaches to address this challenge—deploy, scale, monitor, and maintain the architecture in-house or pay for a Managed Kafka solution that handles this for them. Deciding between do-it-yourself(DIY) or a managed cloud approach depends on a multitude of factors including resources, budget, timeline, and special project requirements. This article discusses how to choose whether a managed cloud event streaming platform or building it yourself is the best option for your team.
In this guide, we will:
- Review the market landscape for prominent Managed Apache Kafka Solutions
- Discuss DIY event streaming solutions including Apache Kafka as well as suites of tools from Cloud Service Providers
- Compare the benefits vs. drawbacks of using a Managed Kafka solution vs. building event streaming infrastructure in-house
- Learn which Apache Kafka event streaming solution is recommended for the different requirements of SMB and enterprise organizations in support for web, mobile, & IoT.
Managed Apache Kafka Cloud Solutions: Marketplace
Distributed cloud architecture spans more than one data center in a similar manner to the way that elastic cluster servers extend the traditional vertical stack model of hardware. In both instances, the virtualization of hardware resources through virtual machines (VMs) and containers is assisted by software-defined networking (SDN) and APIs so that data from hundreds or thousands of microservices can be combined in the construction of custom web/mobile application runtimes.
Within the different layers of abstraction in data center operations, there are now many major IT companies and startups offering software and hardware products, as well as contracting, development, and integrator services. Event streaming solutions built on Apache Kafka form their own development ecosystem, where there is a wide variety of features and functionality that is increasingly being launched in managed cloud products to fit the requirements of DevOps teams. This includes production monitoring and network analytics.

The main advantage of managed Apache Kafka platforms is that the companies all include teams of leading data center technicians with years of experience in enterprise best practices. It can be especially expensive for SMBs to staff and provision infrastructure internally for 24/7/365 on-prem management of event streaming resources in data centers. These products help SMBs to jump-start using Apache Kafka event streaming with a quicker time-to-implement and at an affordable price without absorbing the risk of having to build and manage it themselves.
The pricing on managed cloud plans varies with some offering a monthly/annual subscription model and others being calculated under the “pay-as-you-go” billing model. Metered billing is typically based on the amount of compute, bandwidth, and storage consumed by the event streaming resource requirements. Keen offers monthly subscriptions starting as low as $149 for a set amount of events captured and queried. When comparing pricing for the various options, it is important to keep in mind the full scope of services including customer support, premium features, and features offered by some solutions but not others. For example, Keen and Confluent offer solutions for storage and analytics while this would require additional configuration with tools like Aiven, CloudKarafka, and Instaclustr.
Apache Kafka and Cloud Platforms Event Streaming Solutions: Public Cloud
In the enterprise solutions marketplace, there is little fundamental difference in the operational functionality of software between private and public cloud platforms. AWS Outposts, Google Anthos, and Microsoft Azure Stack allow businesses to run the same stack software on-premises as in the cloud to take advantage of the most recent industry innovation in data center management. These products make hybrid and multi-cloud architecture operate seamlessly with automated elasticity to support the requirements of high-performance computer networks.
DIY approaches to event streaming architecture can be implemented in a wide range of methods on both public and private cloud hardware. When building with Apache Kafka, teams have the advantage of being able to leverage the open-source development community and the Apache Software Foundation where programmers from thousands of different companies work together towards the goal of vendor-agnostic interoperability. Proprietary DIY streaming solutions are also available from the major cloud service providers. Although the focus of this article is to compare Kafka-based event streaming solutions, the below public cloud solutions should also be considered for a DIY implementation.
Public Cloud Solutions – Event Streaming Architecture:
- Google Cloud Platform Dataflow allows developers to build stream analytics with real-time AI/ML processing on TensorFlow TPUs using the Apache Beam SDK.
- Microsoft Azure Event Hubs supports millions of events per second with Kafka APIs that direct data to blob or data lake storage to build streaming analytics on Azure hardware.

Comparing these solutions is outside the scope of this article, but we do cover why we chose Apache Kafka over Amazon Kinesis to build the Keen platform.
SMBs with advanced IT departments have various degrees of difficulty managing their event streaming service layer in support of apps and services. Many enterprise corporations have already committed to event messaging systems as their data-driven operations’ central nervous system. Digital-native and cloud-native standards help organizations adopt data-driven methodologies across verticals and eliminate data silos. IT teams should determine the ideal solutions.
Many businesses choose DIY approaches to save money on software development, application runtime support, batch processing, and expensive managed cloud subscription plans. Other organizations choose DIY methods to advance custom configurations for application support that managed services will not provide. DIY methods allow IT departments to use their preferred choice of hybrid and multi-cloud solutions to build event streaming architecture.
Managed Apache Kafka vs. DIY: How to Choose?
Any organization considering adoption of Apache Kafka as an event streaming solution is recommended to first start with a complete audit of all IT resources. There are different requirements of SMB and enterprise in support for websites, mobile apps, & IoT. Many complex organizations are using Kafka event streaming as their corporate CNS, integrating all products and services in real-time analytics.
It is important to consider the way that API data will be generated from software applications, devices, and users to create event records. Each IT department will need to build a strategy for which platform events will be recorded as data points and build additional processing pipelines for the data to be used in interactive constructs like DXPs or real-time logistical search. The total cost of implementation includes programming custom software to support event streams.
After the stream events are programmed, IT managers will be able to calculate the expected message queue processing requirements based on the web/mobile application or IoT products that are being supported. Create estimates for the total volume of events per second, minute, hour, etc. that are expected on the network. From this estimate, it should be possible to begin to determine the level of hardware support required for real-time processing of event streams from all applications and the persistent storage capacity that is needed over time to store the data.
Managed Apache Kafka vs DIY: Pros & Cons
After conducting an IT audit, a business should have a clearer understanding of the budget, time, and resources needed to implement usable event streaming infrastructure and analytics. Keeping this information in mind, the next step is to evaluate the trade-offs between the event streaming implementation options.
Managed Cloud solutions are ideal for businesses with smaller IT teams who don’t have the time or resources to deploy and maintain custom event streaming infrastructure. Instead, they can pay for a monthly subscription and have experts deploy, scale, log, and monitor their infrastructure. Subscription plans at Keen start at $149 per month. Managed event streaming platforms also offer APIs and SDKs for streaming and analytics that allow development teams to get up and running in weeks. DIY approaches, on the other hand, can take months or even years to implement but allow for more flexibility in configuration.
Trade-offs – Managed Cloud Event Streaming Architecture:
- Managed cloud services help SMBs adopt Apache Kafka event streaming architecture on an organizational level more quickly, affordably, and efficiently for engineering teams without the risk of building in-house.
