A company’s ability to scalable infrastructure support a high volume of simultaneous accesses to its online platforms has become an essential competitive differentiator. Scalability of IT infrastructure is not just a luxury, but a necessity to ensure the availability and optimal performance of applications, regardless of the volume of traffic.
This article will guide you through building a scalable infrastructure on AWS using a proven architecture that includes EC2 instances, RDS MySQL with read replica, WAF, Load Balancer, , CloudFront with S3 Bucket, Lambda, API Gateway, and Cloudflare for DNS and cache management.
1. EC2 Instances for Application Hosting
EC2 instances provide the flexibility to scale compute resources vertically and horizontally. Instance type selection is critical, with options ranging from compute-, memorynstances depending on specific application .
Using Auto-Scaling Groups allows the number of EC2 instances to automatically increase or decrease on metrics such as CPU usage or network traffic, ensuring that the application remains resilient during variations in demand.
2. RDS MySQL with Read Replica
Amazon RDS makes it easy to set up, operate, and scale relational databases in the cloud. When you use RDS MySQL with read mexico phone number list replicas, you not only take advantage of asynchronous replication to distribute the read load between the primary instance and replicas, but you also increase database availability.
This allows you to perform maintenance and backups on the primary instance without interrupting service, as the replicas can continue to serve read requests.
3. Protection with WAF and Load Balancer
AWS WAF lets you create custom rules that block common and specific attack patterns, protecting your application essential guide to successfully planning and implementing your online store from vulnerability exploits and DDoS attacks. When with Application Load Balancer (ALB) or CloudFront, WAF becomes an essential security layer.
ALB intelligently distributes traffic across EC2 instances, improving performance and fault tolerance. It can be to perform health checks, directing traffic only to healthy instances, thus ensuring high availability.
4. Redis for Session Management
Using Redis, an in-memory data structure store, to manage sessions allows extremely fast access to this data, crucial for applications that depend on personalization and agility in retrieving session information.
ElastiCache for b2b phone list provides a service that makes it easy to deploy, operate, and scale an in-memory data store in the cloud, removing the complexity of managing a high-performance caching environment.

5. Cloudflare and CloudFront with S3 Bucket for Content Delivery
Cloudflare acts as a CDN (Content Delivery Network) in front of your AWS architecture, managing DNS and providing content caching to latency and traffic to your origin servers.
Amazon CloudFront, with Amazon S3, provides a globally content delivery network that caches copies of static and dynamic content. This minimizes latency by serving content that is geographically closest to the end user, while the load on application servers.
6. Lambda and API Gateway for Mobile Applications
AWS Lambda lets you execute code in ! response to events without having to provision or manage servers! ideal for specific tasks that require rapid response, such as transaction processing or real-time data manipulation.
