Serverless Services & Deployment v1

Serverless computing is the most efficient way to design new applications. It is a cloud computing model that enables developers to build and run the application code without managing the backend infrastructure required for the deployment and hosting of the website. Serverless does not mean ‘no servers’, it simply means that the backend is provided by the cloud service provider and the front end is developed by the developers. It allows the developers to focus more on the front end and the business logic for the application. The application code is written by developers is deployed to the containers provided by the cloud service provider. In serverless computing the organization does not pay for the idle time, the pay-as-you-use model gives businesses huge cost savings as the backend is provisioned on demand.

About Serverless As A Service

In the serverless computing model, the cloud service provider handles the provisioning of cloud infrastructure, which is required to run the application code, scaling infrastructure up or down based on demand. They are also responsible for the routine infrastructure management and maintenance of an operating system that includes upgrades and patches, capacity planning, system monitoring, and more.

The biggest advantage of the serverless model is the companies never have to pay for the idle capacity. The CSP spins up and provides the required computing resources on-demand when the code executes and scales it ‘back to zero’ when the execution stops.

Examples Of Serverless Application Development

The growing popularity of cloud computing and microservices combined with the demand for greater innovation and agility without increasing costs has contributed significantly to the prevalence of serverless applications. Notable use cases include:

Slack:

Serverless is ideal for independent task-based applications such as chatbots and can save on operational costs since billing is based on the actual number of requests. Slack, a popular, cloud-based business communication platform, uses a serverless application called marbot to send notifications from Amazon Web Services (AWS) to DevOps teams through Slack.

HomeAway:

Reducing development time and server costs while simplifying the build process are goals that universally appeal to business teams and IT teams. HomeAway relied on Google Cloud Functions to develop an app that allowed users to search and comment on the recommendations of travelers in real time, even in areas without an internet connection. The cloud services available through Cloud Firestore and Cloud Functions made it possible to set up the infrastructure within minutes and deploy the app within six weeks with just one full-time developer.

GreenQ:

Garbage pick-up and disposal is an industry that may not seem to require innovative technology, but GreenQ took a sophisticated approach to streamline and improve waste management by using IBM OpenWhisk to create an Iot platform that uses hardware installed on garbage trucks to collect key metrics such as pickup time, location, and load weight. The auto-scaling available through serverless
was particularly valuable due to the fluctuation of infrastructure demands based on the number of customers and
trucks at any given time.

Coca-Cola:

Soft drink giant Coca-Cola has enthusiastically embraced serverless after its implementation in vending machines resulted in significant savings. Whenever a beverage is purchased, the payment gateway makes a call to the AWS API Gateway and triggers an AWS Lambda function to complete the transaction. Since vending machines must communicate with headquarters for inventory and marketing purposes, the ability to pay per request rather than operating at full capacity had a substantial impact on reducing costs.

Benefits Of Serverless Computing Model

The serverless computing model offers numerous technical and business benefits to the development teams in an organization or individual developers working on an independent project:

Versatility

Serverless is a polyglot environment, which means the developers can code in any language or framework – Python, Java, Node.JS, React.JS, or any other preferred language.

Pay for Execution Only

The counter starts when the request is made and it is turned off when the execution is complete. If we compare this to the traditional cloud models like IaaS (Information as a Service) in which the teams have to pay for the infrastructure, Virtual Machines & other resources needed to run the application, the cost savings are huge.

Optimized Developers’ Time

As the development teams focus on the front end without worrying about the infrastructure they can achieve major breakthroughs in designing business logic as they can focus more on the business problem rather than the technical challenges.

Cost-Effective

For dynamic workloads, parallel processing, stream processing, and data processing tasks, the serverless model can be both fast and cost-effective as compared to other models

Streamlined DevOps Cycles

Serverless helps to simplify the deployment of an application and simplify the DevOps as developers no longer spend time configuring and defining the infrastructure needed to integrate, test, develop and deploy the code.

Quick Turnaround

As serverless works as FaaS (Function as a Service) and more, it works like an API call which is much faster than the traditional ways. It significantly cuts down the time to market.

Frequently Asked Questions

What is Serverless Computing?

Although ‘Serverless’ explicitly means ‘no server’, its technical meaning is servers which are managed by Cloud Service Providers (CPS), thereby being invisible to the clients. Serverless is a cloud computing application development and execution model that enables developers to build and run application code without provisioning or managing servers or backend infrastructure. It enables businesses to prioritise front end development. The only remaining requisite for developers is to then write/update code, which is then exported to containers, manager by CPS.

How does serverless computing aid the business financially?

Most of the businesses operating their services using on-premise architecture often use only a marginal( Usually 20-30%) portion of their total server capacity. This is often due to the recruitment of servers for Disaster Recovery Requirements and high availability of other servers. On top of that, owing to the inclusion of most of the networking, security, and DevOps management tasks in the CPS’s cost of service, serverless computing can lower the total cost of ownership.

What are the security and integrity features provided by Serverless Computing?

The modularity of serverless applications can increase the attack surface. Furthermore, because data is constantly transferred between third-party components and serverless functions, it is vulnerable to interception. Different CPS clients provide different security models for their serverless clients. CPS clients manage many additional layers of infrastructure, such as operating systems and networking, with serverless. If you follow the principles of least privilege and best practises for securing a serverless application, you can secure each resource with granular permissions using familiar tools like AWS IAM, which can help you give your serverless applications a robust security posture.
