AWS Lambda vs Azure Service Fabric: What are the differences?
- Deployment and Scaling: AWS Lambda is a serverless computing service where the infrastructure is managed by AWS, allowing developers to focus on writing code without worrying about server management. Azure Service Fabric, on the other hand, is a microservices platform that provides more control over deployment and scaling, making it suitable for complex applications that require fine-tuning of resources.
- Programming Languages: AWS Lambda supports a variety of programming languages such as Node.js, Python, Java, and C#, while Azure Service Fabric has wider language support due to its ability to work with any language that can be compiled to a .NET assembly, giving developers more flexibility in language choice.
- Pricing Model: AWS Lambda follows a pay-as-you-go pricing model based on the number of requests and execution time, making it cost-effective for sporadic workloads. In contrast, Azure Service Fabric requires a monthly fee per virtual machine, potentially resulting in higher costs for sustained and resource-intensive applications.
- High Availability: AWS Lambda automatically scales the infrastructure to handle incoming requests, ensuring high availability without user intervention. Azure Service Fabric provides high availability through its built-in stateful and stateless services, allowing developers to design applications that can withstand failures and maintain uptime.
- Development Environment: AWS Lambda provides a simple development environment with limited debugging capabilities, making it suitable for quick prototyping and testing. Azure Service Fabric offers a more comprehensive development environment with rich debugging tools and integration with Visual Studio, ideal for complex applications that require thorough testing and debugging.
- Integration with Other Services: AWS Lambda seamlessly integrates with various AWS services such as S3, DynamoDB, and API Gateway, enabling developers to build serverless architectures. Azure Service Fabric integrates well with other Azure services, providing a cohesive ecosystem for building and deploying applications that leverage Azure's infrastructure.
In Summary, AWS Lambda is a serverless computing service with automated scalability, while Azure Service Fabric is a microservices platform offering more control over deployment and scaling.
When adding a new feature to Checkly rearchitecting some older piece, I tend to pick Heroku for rolling it out. But not always, because sometimes I pick AWS Lambda . The short story:
- Developer Experience trumps everything.
- AWS Lambda is cheap. Up to a limit though. This impact not only your wallet.
- If you need geographic spread, AWS is lonely at the top.
Recently, I was doing a brainstorm at a startup here in Berlin on the future of their infrastructure. They were ready to move on from their initial, almost 100% Ec2 + Chef based setup. Everything was on the table. But we crossed out a lot quite quickly:
- Pure, uncut, self hosted Kubernetes — way too much complexity
- Managed Kubernetes in various flavors — still too much complexity
- Zeit — Maybe, but no Docker support
- Elastic Beanstalk — Maybe, bit old but does the job
- Heroku
- Lambda
It became clear a mix of PaaS and FaaS was the way to go. What a surprise! That is exactly what I use for Checkly! But when do you pick which model?
I chopped that question up into the following categories:
- Developer Experience / DX 🤓
- Ops Experience / OX 🐂 (?)
- Cost 💵
- Lock in 🔐
