Here's a comprehensive list of serverless computing alternatives offered by various cloud platforms, including on-premises solutions that leverage open-source or private cloud technologies for serverless capabilities.

```mediawiki

• AWS Lambda: A serverless compute service that lets you run code without provisioning or managing servers.
• Amazon API Gateway: Allows you to create, publish, maintain, monitor, and secure APIs at any scale.

• Azure Functions: Enables you to run event-driven code without having to explicitly provision or manage infrastructure.
• Azure Logic Apps: Helps you automate workflows, integrate apps, data, services, and systems.

• Google Cloud Functions: A lightweight, event-based, asynchronous compute solution that allows you to create small, single-purpose functions.
• Google App Engine: A fully managed, serverless platform for building highly scalable web applications and APIs.

• IBM Cloud Functions: Based on Apache OpenWhisk, it provides an event-driven compute service for executing code in response to events or direct invocations.

• Oracle Cloud Functions: A managed, multi-tenant, scalable, on-demand, compute environment that runs code in response to events or direct invocations.

• Knative: An open-source Kubernetes-based platform to build, deploy, and manage modern serverless workloads.

• While VMWare traditionally focuses on virtualization, with VMware Tanzu, it steps into the Kubernetes ecosystem, potentially paving the way for serverless capabilities on Kubernetes clusters.

• Alibaba Cloud Function Compute: A fully-managed event-driven compute service that allows you to build applications without thinking about servers.

• As of my last update, DigitalOcean hadn't announced a native serverless compute service, but its cloud computing platform supports deploying applications that can benefit from serverless architectures.

• Huawei Cloud FunctionGraph: A fully managed, event-driven compute service that helps you focus on your code without managing servers.

• Tencent Cloud Serverless Cloud Function (SCF): An event-driven, fully managed computing service that enables you to focus on writing and uploading code without managing servers.

• On-premises environments can leverage open-source projects like OpenFaaS, Kubeless, and Fission for serverless computing capabilities, running on top of Kubernetes for orchestrating containerized applications.

```

This list showcases the diverse range of serverless computing options available across major cloud providers and technologies, enabling organizations to deploy applications without the hassle of managing servers, focusing solely on writing code that scales automatically and efficiently.

Cloud Serverless Best Practices

Implementing best practices for serverless computing can significantly enhance the efficiency, reliability, and security of your serverless applications. Here’s a structured guide on optimizing serverless architecture.

```mediawiki

Understanding and implementing best practices in serverless computing is crucial for leveraging the full potential of cloud serverless architectures, ensuring applications are scalable, cost-effective, and secure.

Design your functions to be stateless, allowing them to scale horizontally without relying on any particular instance of a function.

Keep your function execution time as short as possible to reduce latency and costs. Profile and optimize your code to remove any unnecessary processing.

Utilize asynchronous invocation for functions that don't require immediate responses, improving system throughput and efficiency.

Design robust error handling within your functions, including retries and dead letter queues, to manage transient and persistent errors gracefully.

Apply the principle of least privilege by granting minimal permissions needed for your functions to execute, reducing the potential impact of security breaches.

Optimize dependencies and the size of your deployment package to reduce cold start times, ensuring faster function execution, especially for critical applications.

Use caching for frequently accessed data within your serverless applications to minimize database hits and improve response times.

Architect your serverless applications to handle variable workloads efficiently, utilizing the auto-scaling capabilities of serverless platforms.

Implement comprehensive monitoring and logging to track the performance and health of your serverless applications, facilitating easier debugging and optimization.

Deploy API gateways in front of your serverless functions to manage access, monitor traffic, and offload authentication.

Carefully manage dependencies to keep your functions lightweight and to reduce the time taken to start and execute your functions.

Break down large, monolithic functions into smaller, composable functions to improve maintainability, scalability, and deployment flexibility.

Version your serverless functions and configurations for better manageability and to support rollback in case of issues.

Store configuration and secrets in environment variables, not in function code, to enhance security and simplify configuration changes.

Continuously review your serverless architecture against evolving best practices and application requirements to ensure optimal performance.

Ensure your serverless functions are idempotent where possible, especially for operations that may be retried, to prevent unintended side effects.

Use custom domains with your serverless applications to provide a branded and professional user experience.

Be mindful of the pricing model of serverless services and design your applications to minimize unnecessary executions, data transfers, and storage.

Adhering to these cloud serverless best practices will help organizations build efficient, secure, and highly scalable serverless applications. Continuous evaluation and adjustment of these practices are key to maximizing the benefits of serverless computing. ```

These guidelines provide a roadmap for building and managing serverless applications in the cloud, focusing on performance, security, and cost optimization to fully leverage the serverless model's advantages.

Snippet from Wikipedia: Serverless computing

Serverless computing is "a cloud service category in which the customer can use different cloud capability types without the customer having to provision, deploy and manage either hardware or software resources, other than providing customer application code or providing customer data. Serverless computing represents a form of virtualized computing." according to ISO/IEC 22123-2. Serverless computing is a broad ecosystem that includes the cloud provider, Function as a Service, managed services, tools, frameworks, engineers, stakeholders, and other interconnected elements, according to Sheen Brisals.
