What is Serverless Computing?

Serverless computing is a way to use the cloud where the cloud provider takes care of the server and resources. Developers can make and run apps without handling servers or databases. This lets developers focus on coding and adding features, not on the tech stuff.

The Origins of Serverless

Google started serverless computing in 2008 with Google App Engine. This platform helped developers make and host web apps in Google’s data centers. The term “serverless” came up in 2012.

Then, in 2014, Amazon launched AWS Lambda. This was the first serverless platform. It let developers run code when certain events happened, without managing servers. Big names in serverless include Microsoft Azure Functions, Google Cloud Functions, IBM Cloud Code Engine, Oracle Cloud Infrastructure (OCI) Functions, Cloudflare Workers, and Alibaba Function Compute.

Serverless and FaaS

Serverless computing is also known as Backend-as-a-Service (BaaS) or Function-as-a-Service (FaaS). FaaS is when developers write custom apps that run in managed containers. Big cloud companies like AWS, Azure, Google, and IBM offer FaaS options like AWS Lambda and Azure Functions.

Serverless Databases and Storage

Serverless also covers databases and storage. Serverless databases and serverless storage are cloud services that handle scaling and management automatically. This lets developers focus on data and apps, not the tech. Examples are Amazon DynamoDB, Azure Cosmos DB, and Google Cloud Datastore.

The Serverless Ecosystem

The world of serverless computing is more than just function-as-a-service (FaaS) platforms. It includes many services and technologies that help make Cloud-Native Applications and Containers. These tools work together to make it easier to develop and use serverless computing.

API Gateways

API gateways are a big part of the serverless world. They act as middlemen between web apps and serverless functions. They manage things like HTTP routes, client info, and limits on how much data can be used. This makes sure apps can safely and quickly talk to serverless functions.

Serverless and Event-Driven Architecture

Serverless computing is great for event-driven and stream-processing tasks. It uses stateless functions that handle one event at a time. This makes it perfect for event-driven architecture, which is all about handling events efficiently.

With serverless, developers can make apps that scale well and respond fast. These apps can react to different events in real-time.

Serverless Platform Key Features
AWS Lambda – Started serverless computing in 2014 at re:Invent
– Lambda@Edge for running functions at the CDN edge
– Lambda Layers for sharing code and settings
Oracle Cloud Functions – Supports various programming languages like Go, Java, Python, and Node
Alibaba Cloud Function – Offers fee-free services for 400,000 CU-second computations and 1,000,000 invocations per month

The serverless ecosystem is always getting better. Cloud providers and open-source projects are working to make it easier for developers. They aim to improve performance and open up more uses for Cloud-Native Applications and Containers.

Comparing Serverless to PaaS, Containers, and VMs

The cloud computing world is always changing. Many models help with making and deploying apps. Serverless computing, PaaS, containers, and VMs each have their own role. It’s key to know their strengths and weaknesses for making good choices in cloud-native apps.

Edge Computing, AI in Cloud Computing, and Machine Learning in Cloud are big areas where these models matter. Serverless has many benefits that make it stand out.

Serverless is great because it starts up fast, in milliseconds. This is way quicker than PaaS, containers, and VMs. This quick start helps make apps work better and faster, with less work for admins.

Serverless also scales automatically, adjusting resources as needed. This means you don’t have to plan for capacity. Plus, the cloud service provider takes care of upkeep, making your setup reliable and cheap.

Feature Serverless PaaS Containers VMs
Provisioning Time Milliseconds Minutes to Hours Minutes to Hours Minutes to Hours
Administrative Burden Low (CSP manages) Moderate Moderate High
Autoscaling Automatic (including scaling to zero) Automatic Manual Manual
Maintenance 100% by CSP Shared between CSP and customer Shared between CSP and customer Customer responsibility
Billing Pay-per-use, more favorable pricing Monthly subscription, less flexible Per-container, more granular Per-VM, less flexible

Also, serverless apps don’t keep track of their own state, which makes them simpler and more resilient. This, along with the CSP’s high availability and disaster recovery, makes serverless great for many uses. This includes Edge Computing, AI in Cloud Computing, and Machine Learning in Cloud apps.

But, serverless also has its downsides, like the risk of being tied to one provider and worries about security and costs. Still, as cloud computing keeps changing, serverless is set to become more important. It might even beat traditional PaaS, containers, and VMs in some ways.

Serverless Computing

Serverless, Kubernetes, and Knative

The world of cloud computing is always changing. Now, serverless tech and container platforms are coming together. Kubernetes is a big name in making and managing cloud-native apps. Serverless computing lets developers build apps without worrying about servers.

Serverless apps run in containers, and Kubernetes can manage these apps. But, you need special software to link Kubernetes with a cloud’s serverless platform. That’s where Knative comes in. It’s an open-source tool that makes any container run as a serverless app on any Kubernetes cloud.

Knative makes managing the cloud’s behind-the-scenes stuff easy. It handles things like network routes, event triggers, and making apps grow or shrink as needed. This makes making cloud-native applications easier for developers. They can just write code without worrying about the tech stuff.

Using Knative with Kubernetes has many perks. It uses Kubernetes to manage serverless workloads in a way that’s native to Kubernetes. This means it helps avoid being tied to one cloud provider. It lets companies run serverless apps on different clouds, including hybrids and multi-cloud setups.

Knative has cool features like making apps grow or shrink on their own, managing settings and versions, building images in the cloud, splitting traffic, and an event system. These features make making, deploying, and managing cloud-native applications easier. It’s a great choice for companies going serverless.

As more companies want fast, flexible, and affordable cloud-native applications, the mix of Kubernetes and Knative is key. It’s set to change the future of Containers and serverless computing.
