The demands of the current market necessitate constant adaptations for companies. To remain competitive, they must adapt to the ever-evolving landscape of cloud computing. A robust and secure architecture is essential for the seamless operation and scalability of applications.
This blog demonstrates how the restaurant industry can gain a competitive edge through the power of technology, specifically by utilizing AWS cloud architecture. We will highlight the benefits of high availability and scalability in this context.
The subnet architecture includes a single EC2 instance that services both the front and back end. Additionally, there are separate EC2 development instances dedicated to evolving the platform, enabling seamless integration of new features. A Gateway is in place to facilitate communication between these instances, ensuring that the environment, even with a single EC2, can receive necessary updates and patches efficiently.
The primary goal of this enhancement is to significantly boost the platform's availability and lay the groundwork for scalable integrations in the future.
Transition to Advanced Architecture:To enhance system functionality and achieve the desired quality attributes,
we are progressively transitioning to a new architecture. Figure 2 illustrates the transformative
journey to this final version.
Our updated setup retains a private subnet hosting RDS databases. This includes one for production, handling user data, and another for development purposes to facilitate testing and modifications. These databases are configured for Multi-AZ Deployment, ensuring high availability and failover support - critical elements for the robustness of our business operations.
ASGs play a pivotal role in managing front-end and back-end production instances across multiple availability zones. This structure not only enhances scalability but also bolsters resilience against potential disruptions.
The environment's vanguard features two ALBs, distributed across multiple zones. These ALBs efficiently distribute incoming application traffic among multiple instances. This approach optimizes performance, ensures fault tolerance, and enhances overall availability.
In this architecture, security is of paramount importance. We employ Key Management Service (KMS) for meticulous key management, underscoring our commitment to security best practices. Additionally, to prioritize secure communications, a TLS Certificate has been deployed to encrypt data in transit. For added protection, integrating a Web Application Firewall (WAF) is a strategic move to shield the application from web-based threats.
The final component involves utilizing Route 53 Hosted Zone service for efficient domain name management and DNS routing. This service is essential for translating friendly domain names into IP addresses, ensuring continuous online visibility and accessibility.
The recent architecture upgrade marks a significant milestone in our platform's evolution. This enhancement not only empowers our developers to innovate and add new features seamlessly but also significantly reduces downtime. We've achieved this through a scalable process that smoothly integrates new services into the architecture, ensuring continuous operation and service availability for our users.
Key to this upgrade has been the implementation of robust practices aimed at safeguarding sensitive information while maintaining uninterrupted service. The AWS architecture we've adopted reflects a meticulously planned approach to cloud infrastructure design. This design cleverly balances the need for development agility with the requirements of production stability.
By leveraging a suite of AWS services, we've created an environment that is not only secure and scalable but also boasts high availability. This architecture is not just about meeting the current needs of our application; it's a forward-thinking solution that supports our platform's ongoing growth and expansion, preparing us for the challenges and opportunities of the future.
