IOT has been a reality for a while and connected automobile technology in the Travel & Transport industry is growing at a fast pace. To remain competitive, start-ups need modern solutions for modern world problems. Deploying solutions on Cloud is now not enough, robust solutions are required which are available, scalable, and at the same time offload the hassle of managing resources.
This blog brings you a perspective about adopting a serverless architecture on AWS to meet business needs without worrying about resources management.
Traditional vs Serverless
The below illustration will describe a common monolithic architecture and recommended serverless architecture for deploying a connected automobile solution on Cloud.
Traditional 3-tier architecture
The web server serves the front-end of the application and connects to application servers Business logic and authentication are processed by the application server Database servers store and process the user's data Load balancer, auto-scaling, and firewall managing the incoming traffic security and load balancing
The Traditional architecture has a monolithic application which prevents the independent scaling of the layers resulting in inefficiencies and resource overutilization
AWS serverless architecture also consists of a three-tier implementation -
The above multi-tier architecture enables a general framework to ensure decoupled and independently scalable application components(services) can be separately developed, managed, and maintained. In the above-mentioned architecture, each of the application services is decoupled and independently deployed and operated. AWS native serverless services have simplified the process of deploying such applications to production and removing the overhead associated with traditional server management. Amazon API Gateway is used for creating and managing APIs, and AWS Lambda, a service for running arbitrary code functions
The key benefits that this architecture brings are
No server management Developers are only charged for the server space they use, reducing the cost Serverless architectures are inherently scalable Quick deployments and updates are a reality Code can run closer to the end-user, decreasing latency Best practices
Now that we’ve shown you how to build a connected automobiles solution on AWS with a Serverless pattern, make sure you follow these best practices to effectively build, deploy, and monitor the solution stack:
Infrastructure as Code (IaC).
A well-defined, repeatable infrastructure is important for managing any solution stack.
AWS CloudFormation allows you to treat your infrastructure as code and provides a relatively easy way to model a collection of related AWS and third-party resources.
AWS Serverless Application Model (AWS SAM).
An open-source framework.
Use it to build serverless applications on AWS.
AWS CodePipeline is a fully managed continuous delivery service that automates your release pipelines for fast and reliable application and infrastructure updates.
AWS CodeStar. Allows you to quickly develop, build, and deploy applications on AWS. It provides a unified user interface, enabling you to manage all of your software development activities in one place.
AWS Well-Architected Framework.
Provides a mechanism for regularly evaluating your workloads, identifying high-risk issues, and recording your improvements.
Serverless Applications Lens.
Documents how to design, deploy, and architect serverless application workloads.
AWS provides many services that help you monitor and understand your applications, including Amazon CloudWatch, AWS CloudTrail, and AWS X-Ray. Conclusion
In this blog post, we described how serverless architecture can be used to benefit the automobile industry with a connected solution
