What is serverless computing?
Serverless Computing
At ecom industries, we specialize in leveraging AWS services to
create robust, scalable, and cost-effective solutions for a
variety of business needs. From building Progressive Web Apps
(PWAs) and mobile applications to deploying machine learning
(ML) pipelines, we harness the full power of AWS's serverless
architecture alongside open-source tools to deliver cutting-edge
solutions. Let's dive deeper into how we utilize AWS and other
technologies in our stack to empower businesses.
Serverless computing allows developers to focus solely on their code and application logic, leaving the infrastructure management to cloud providers. Instead of managing servers, provisioning resources, or scaling manually, serverless services like AWS Lambda dynamically handle all these tasks. This approach aligns perfectly with modern DevOps practices and microservices architecture.
Why Choose AWS for Serverless Computing?
AWS leads the serverless revolution with services that provide scalability, flexibility, and cost efficiency. From compute to data storage, AWS offers an unparalleled suite of tools that seamlessly integrate, enabling developers to build end-to-end applications with ease.
Key advantages include:
Pay-per-use: Only pay for the compute and storage you use.Built-in scalability: Automatically adjusts to traffic demands.Rich ecosystem: Integrates with a wide array of AWS services for diverse use cases.How We Build Applications at ecom industries
Our approach to application development incorporates a
comprehensive stack of AWS services and open-source tools,
enabling us to address diverse business needs. Here's a look at
our architecture:
Backend and Data Processing
1. AWS Lambda: As a serverless compute service, Lambda allows us to execute code in response to events (e.g., API Gateway triggers, DynamoDB streams) without provisioning or managing servers.Key Use Case: Event-driven applications with DynamoDB Streams and Kinesis Streams for real-time data processing.Framework: We use the Serverless Framework to simplify deployments and enable infrastructure-as-code (IaC).2. Amazon DynamoDB: Our go-to NoSQL database for serverless applications. We optimize DynamoDB with advanced partition and sort key design for high efficiency and low cost.DynamoDB Streams: Paired with AWS Lambda, DynamoDB Streams enable real-time event-driven architectures.Kinesis Data Streams and Firehose: For machine learning pipelines, we use Kinesis to process and ingest data into S3 or Redshift for training models in SageMaker.3. Amazon SageMaker: Used for building, training, and deploying ML models. We leverage Jupyter Labs within SageMaker to collaborate on custom ML pipelines.4. Data Warehousing:
Amazon Athena: A serverless query service for analyzing data stored in S3 using SQL.Amazon Redshift: A fully managed data warehouse that integrates seamlessly with ML workflows and BI tools.Frontend Development
React.js: The cornerstone of our Progressive Web Apps (PWAs) and mobile applications.
Cross-platform applications: Coupled with APIs, React delivers native-like experiences on both iOS and Android.Infrastructure and Deployment
Infrastructure as Code (IaC):
AWS CloudFormation: Automates resource provisioning.Serverless Framework: Simplifies deployment pipelines, ensuring version control and repeatability.Continuous Integration/Continuous Deployment (CI/CD):
AWS CodeBuild: Handles build automation with ease.AWS CodePipeline: Automates the release process, ensuring a smooth deployment workflow.Security and Authentication
Amazon Cognito: Simplifies user authentication and authorization, supporting both enterprise-grade security and social logins.AWS Key Management Service (KMS): Provides robust encryption for sensitive data using RSA PKI and symmetric keys.APIs and Microservices
Amazon API Gateway: Facilitates secure, scalable APIs with built-in monitoring and throttling.OpenFaaS: For on-premise deployments, we use OpenFaaS to run
serverless functions in environments where AWS isn't an
option.Kubernetes (EKS): In hybrid scenarios, we leverage Kubernetes for container orchestration, ensuring portability and scalability.Diving Deeper: Advanced Use Cases
Machine Learning Pipelines
Our ML pipelines integrate real-time data processing using Kinesis Streams with SageMaker to train and deploy models. For instance:
Data ingestion: Kinesis Firehose streams data into S3.Training: SageMaker trains models on structured data stored in Redshift.Deployment: Models are deployed as endpoints for real-time inference.Blockchain and Immutable Ledgers
For industries requiring verifiable transactions:
Amazon QLDB: Ensures immutability for financial and compliance applications.IPFS Integration: We use IPFS for decentralized file storage, particularly in NFT and blockchain applications.Data Encryption and Compliance
Using AWS KMS and other encryption tools, we implement secure, compliant systems for sensitive applications, particularly in healthcare and finance.The Role of Open-Source and Hybrid Cloud
While AWS forms the backbone of our infrastructure, we extend its capabilities with open-source tools:
OpenFaaS: Ideal for on-premises serverless computing.Terraform: Used alongside CloudFormation for multi-cloud support.Kubernetes: Enables hybrid solutions for businesses transitioning from on-premises to cloud.Why ecom industries?
At ecom industries, we don't just build software; we create
scalable ecosystems tailored to your needs. By combining AWS
serverless services with open-source tools and deep expertise in
machine learning, blockchain, and data engineering, we deliver
solutions that are:
