Serverless Computing Examples, Features And Use Cases

We’ll talk about the serverless computing Examples, use cases, such as API integration, automated backups, and scalable applications. Improve your cloud approach right now.

Important Features

Let’s examine the main terms used in serverless computing before moving on to the main features that set it apart from other conventional cloud models.

  • Function: This type of code is made to carry out a certain operation, such uploading files, handling HTTP requests, or something else. Every function is made to respond to an event and is independent of the others. A function is invoked to perform a specific activity or to execute code in response to an event.
  • Duration: The time a function takes to run from call to result.
  • Cold Start: The time a serverless platform spends allocating resources before a function runs.
  • The maximum number of instances a function can execute concurrently in response to requests and events is known as the concurrency limit.
  • Timeout: This is the longest a function can run before the serverless platform ends it.

Serverless computing examples

Serverless computing examples

Top cloud providers including AWS Lambda, Google Cloud Functions, Microsoft Azure Functions, and IBM Cloud Code Engine offer popular serverless computing platforms and services. A cloud provider provides the necessary resources for each of these serverless services. The servers are not visible to or accessible by developers in any way.

Serverless Computing Use Cases

Websites and APIs

REST APIs and web apps are developed using serverless computing. The intriguing aspect is that serverless infrastructure is used to build apps, which automatically scale in response to user demands, enhancing the user experience.

Media processing

Media processing is made easier with serverless architecture. The platform handles a single function that satisfies each user’s request without degrading application performance, and users can upload media content from a variety of devices and sizes. For instance, an AWS Lambda function can be used to add a watermark or thumbnail to a picture when a user uploads it using an S3 bucket.

Chatbots

With serverless architecture, developers may create a chatbot that answers consumer enquiries and only pays for the resources it needs. For instance, Slack employs serverless architecture to manage the many requests made by bots in order to prevent underutilization of bandwidth because customer needs change on a daily basis.

Webhooks

Through a webhook HTTP endpoint that gets notifications and completes tasks, you can communicate with SaaS vendors using a serverless platform. For the built-in webhook, this provides automatic scaling, cheap expenses, and little maintenance.

IoT

Coca-Cola’s Freestyle vending machine leverages serverless architectures to let users order, pay, and get payment alerts for their drinks. Coca-Cola stated that after installing serverless architectures on their vending machines, their annual operating costs dropped from about $13,000 to $4,500.

Data processing

Statcast, a product of Major League Baseball Advanced Media, was developed using a serverless architecture to give customers precise and up-to-date sports metrics. It processes data and provides users with baseball game insights using serverless computing.

Event-driven applications

Serverless architecture is used for applications that are event-driven, meaning that a service is triggered when a state or event changes. Serverless platforms can be used to monitor database changes and compare them to quality criteria.

Risks Of Serverless Computing

Risks Of Serverless Computing

Because serverless architecture is distributed, it might be challenging for organizations to secure. Traditional security methods become ineffective as a result of the architecture’s increased flexibility and scalability. Rather than safeguarding the apps themselves, organizations should concentrate on protecting the event-driven and loosely connected parts of applications.

Serverless computing can lead to programs being deployed to production before security teams can solve visibility issues as developers take the lead. The program may be vulnerable to SQL injection, remote command execution, and cross-site scripting.

In serverless computing, data storage and transit also pose security and regulatory risks. Instead of being kept in memory, which could leak when transferred to external sites, data stored in stateless and serverless operations stays cached.

Role of serverless computing in digital transformation

A key component of the digital transformation is serverless computing. First of all, it frees developers from worrying about the underlying infrastructure that will support the code, allowing them to concentrate on building code that provides business value and increase productivity. By removing management overhead, a serverless computing approach can boost developer productivity regardless of the size of the business or vertical industry.

The following are characteristics of a software development environment for serverless computing:

  • Controlled integrated security
  • Autoscaling to accommodate fluctuating traffic demands
  • zero server management

What to look for in a serverless architecture

In order to develop apps from start to finish, organizations should seek for serverless platforms that enable them to access databases, storage, messaging, data analytics, machine learning, and smart assistants.

While some serverless cloud services offer cost savings and scalability, they can also introduce new complications, like vendor lock-in or restricted runtimes, so that’s another crucial factor to take into account when selecting a serverless architecture.

Developers frequently have to choose between the flexibility and portability of containers and the simplicity and speed of serverless computing. For this reason, instead of restricting serverless to compute operations, the majority of organizations gain from a full-stack strategy.
