Different cloud computing models have been in the market for a little while now and are winning over conventional application development systems. Because conventional models require application developers to supervise, maintain, and scale the server setups as per the requirements. These factors eventually create useless overhead for startups or medium-sized organizations that in certain situations get challenging to deal with, particularly with strict budgets and tight deadlines. So, to address these issues, the majority of custom application development service providers nowadays opt for cloud computing models.
And serverless architecture is one of the top cloud computing models gaining immense popularity these days. Also, the serverless web app is the newest kid in the line. With every significant cloud provider focusing on serverless architecture, and significant campaigns being run around the smoothness of the architecture, you must be wondering what these web apps are.
So, serverless web apps are one of the widely accepted models in the cloud engineering realm and have been since the inception of AWS Lambda. Today, these serverless web apps allow development teams to optimize efficiency, scalability, and agility for client-centric apps.
To know more, let’s dive in!
What is a Serverless Web Application?
The serverless web app’s structure is highly based on the Functions as a Service (FaaS) model, enabling different cloud platforms to utilize application code without the entire infrastructure. FaaS also referred to as Compute as a Service (CaaS), is a cutting-edge, fully managed by the providers of cloud services. The code emphasizes business intelligence and then determines an event that drives the work to be done, like an HTTP request. The cloud provider then utilizes the code and sends the findings to the web apps for users to examine.
Some renowned examples of cloud-based service providers include Apache OpenWhisk – IBM Cloud Functions, AWS Lambda, Microsoft Azure Functions, and Google Cloud Functions.
Why Serverless Web Apps?
The following are some significant advantages of serverless web applications:
- Serverless Is Simple To Accomplish
You can easily establish your serverless mode completely. So, if need to examine the app instantly, using no server is the best solution. Because with the help of serverless architecture, you can turn the weeks and months for app utilization into hours and days.
- Minimal Price
Not utilizing the server is the best way to minimize expense. And why? Because it helps eradicate the responsibilities of handling servers, data, and other logical stuff. Without any real expense, serverless architecture takes up little to less computer power and human resources.
- Productive Extensibility
If you plan to be the next conglomerate, you must consider whether your server can support such a load having scalable cloud storage. Hence, opting for a serverless architecture for your apps supports extensive data.
- Enhanced Latency
Serverless architectural functions usually have proper access to international levels. It is seamless to manage customers from every corner of the world. And in this way, you can also measure the performance without interfering with your application.
- Satisfied Clients
This benefit usually relies on the organization in doubt. Serverless properties can result in more happy and satisfied clients. So, any organization that can quickly develop new servers and robust web application elements can easily access the new features and functionalities.
How to Build Serverless Web Apps?
The best way to develop a serverless app is by merging different AWS services. Each service is managed entirely and needs no management or provisioning of servers from your side. So, let’s not see how to build a serverless web app in AWS.
1. Choose Your Web Hosting Provider
To set up an S3 bucket, AWS cues you to submit the mentioned information, including the bucket name – The bucket name should be specific and has not been used previously on Amazon S3 buckets. Therefore, always try to customize the bucket name.
2. Choose a Serverless Backend Service
You can find the availability of Lambda functions in different programming languages, including Ruby, Python, C#, Node.js, PowerShell, Go, and Java. So, when it comes to Lambda, Amazon offers different choices for building Lambda functions.
3. Select a RESTful API
Amazon API Gateway is a supported Amazon service that allows you to design, release, and manage secure APIs.
4. Choose a Database
Amazon DynamoDB is a scalable, highly productive NoSQL-supported cloud database that also manages multiple key-value and document storage types. You can easily host your infrastructure at this level; however, you must ensure the safety of your data and services.
5. Choose a Service to Manage Privileged Access
IAM here helps you manage access to AWS resources and services securely. It allows you to accomplish and support AWS users and groups, granting and denying them access to AWS resources with permissions.
6. Choose a User Administration Service
You can opt for Amazon Cognito, as it’s a management service that allows one to incorporate user sign-up and data synchronization into your web application. Hence, it helps handle user authentication and management for your backend API.
Summing Up!
Serverless architecture is gaining increased prominence in current times. At the same time, the solutions integrated with serverless architecture encounter dynamic shifts and development. Also, utilizing these kinds of web app solutions needs good know-how, new skills, and multiple methodologies in different areas, such as developing, designing, testing, and managing applications. Moreover, it also provides new opportunities for developers to make their work and lives easier.
Here, you can also opt to partner with a trusted web application development company, because, with the right expertise and knowledge of tools in your arsenal, they ensure the success of your serverless app. The experts will help you deliver crucial insights into managed service data, providing you with an extensive view of your serverless web application.
