Development is a process that requires focus and the availability of resources. No developers want to work for resource provisioning and operations management. A developer requires the ability to develop applications and services without having to care about the above-mentioned resource management.
Alibaba Cloud created Function Compute. It is a fully-managed compute service that doesn't require the user to work for any resources or O&M needs. Without the need for infrastructure management, developers can flexibly and reliably run your code.
Function Compute automatically adjusts the resources depending on the traffic demand incursion. For further performance acceleration, it uses a reserved instance. Alongside maintaining latency glitches, this reserved instance also helps with the online migration of applications to Function Compute.
| Programming Language | Support |
| C# | .Net Core 2.1 with HTTP triggers with .NET 2.0 |
| PHP | PHP 7.2 with runtimes HTTP triggers (PSR standard) |
| Node.js | Node.js 6,8, and 10 with HTTP triggers with Express |
| Python | Python 2.7 and 3 with HTTP triggers with WSGI |
| Java | Java 8 with HTTP triggers based on Servlet protocol |
| Custom Runtimes | Custom environments for Ruby, GO, and Lua are supported and can be migrated to Function Compute easily |
| Development Tool | Support |
| Visual Studio Code Extensions | Supports development, debugging, and deployment tools for VS Code |
| FunCraft – Application Development Tool | Supports installation of third-party dependencies, local debug, and resource creation. |
With Function Compute, you have to upload your codes, and the service backend will run it considering the level of elasticity needed. It will record metrics, such as performance, alarms, and query logs, for you to monitor. Since Function Compute is event-driven, whenever an event triggers the service, Function Compute automatically calls to process the event.
Triggers can be invoked with the Function Compute SDK, API, API Gateway, Object Storage Service (OSS), log service, or Table Store. The inclusion of these services gives developers all of the necessary tools and services to build elastic, reliable, and feature-rich applications.
Let's take a look at the Function Compute workflow to understand how it works:
Function Compute scales depending on your traffic peak data and delivers seamless deployment.
Serverless computing resources are a way of providing elastic resources to the developer without any intervention from the developer. Though physical servers are still used for the infrastructure, the developer has no part to play in provisioning any resource. The developer just needs to call the Function Compute service while uploading code with the trigger methods mentioned above.
Alibaba Cloud Function Compute is designed to improve efficiency and to reduce costs. This serverless model of application design lets you focus on the development environment and leave the deployment environment functionality on Function Compute.
With Function Compute, you do not need an answer to the prerequisites of the application or service. The fully-managed setup doesn't require manual intervention for resource provisioning, scales automatically to match the application or service requirement, manages loads automatically, scales the service dynamically, upgrades the server configuration automatically to match resource allocation, and automatically configures the operating system and network configurations.
Aliyun VSCode Extension is a development tool based on the Visual Studio Code (VSCode.) It is a graphical user interface-based tool that can be used for development, debugging, and resource-managing with Function Compute.
Make sure that you have Docker and Visual Studio Code installed before you start to install the VSCode extension.
Fun is a development tool for serverless applications. It works with Function Compute to seamlessly and efficiently provision cloud resources, such as API Gateway and others. It can be used to develop and deploy to Function Compute.
Function Compute offers a wide range of benefits without any of the hassles of typical computing or cloud resources. It is the next generation of fully-managed and event-triggered deployment engines that help the developer and businesses achieve better business continuity. Alibaba Cloud and its services have created a supreme overlay that bridges any gaps in services by integration at the core level. This ensures reliability and scalability to its true form. Understanding what you need and operating with ease is what Function Compute does.
In this article, we will be discussing the scenarios where Function Compute and serverless technology comes into play. We will explain the real-world applications of Function Compute and how to achieve a more integrated and productive system by using a serverless approach.
