Building a scalable frontend deployment pipeline with automated CI\/CD, custom domains, and global delivery<\/strong><\/p>\n

Introduction<\/strong><\/h2>\n

Frontend applications of today need fast deployments, scalability, global reach, and low operational overhead. But plenty of organizations still use traditional server-based hosting where deployments require manual configuration, SSH access, server maintenance, SSL handling, and cache management.<\/p>\n

As frontend applications scale across multiple environments, maintaining frontend infrastructure using EC2 instances, NGINX, and load balancers becomes increasingly difficult and expensive to maintain.<\/p>\n

We created a frontend deployment architecture to make frontend hosting easier and deployments consistent:<\/p>\n

    \n
  • AWS Amplify<\/li>\n
  • Amazon S3<\/li>\n
  • Jenkins CI\/CD<\/li>\n
  • Route53<\/li>\n
  • ACM Certificates<\/li>\n<\/ul>\n

    Problem Statement<\/strong><\/h2>\n

    Before we moved to Amplify-based hosting, we had a couple of operational issues with the frontend deployments:<\/p>\n

      \n
    • Manual deployment tasks<\/li>\n
    • Nginx and EC2 Dependency<\/li>\n
    • Flush Cache Manually<\/li>\n
    • Complexity of SSL Certificates Management<\/li>\n
    • Scaling of infrastructure overhead<\/li>\n
    • Environment config mismatch<\/li>\n<\/ul>\n

      As deployments to multiple environments became more frequent, it became harder and more time consuming to keep things consistent.<\/p>\n

      The objective was to develop a deployment architecture that could:<\/p>\n

        \n
      • Automation of Front-end Deployments<\/li>\n
      • no need to host it on a server<\/li>\n
      • Easier domain and SSL management<\/li>\n
      • Handle multiple environments cleanly<\/li>\n
      • Works well with existing Jenkins based CI\/CD workflows.<\/li>\n<\/ul>\n

        Why We Chose AWS Amplify<\/strong><\/h2>\n

        AWS Amplify is a fully managed service for hosting the frontend of modern web applications.<\/p>\n

        Key features include:<\/p>\n

          \n
        • Front end hosting administration<\/li>\n
        • Global delivery CDN Powered<\/li>\n
        • SSL certificate installation<\/li>\n
        • Deployments from branches<\/li>\n
        • Deployment History Tracking<\/li>\n
        • Support for custom domains<\/li>\n
        • Monitor Requests and Logs<\/li>\n<\/ul>\n

          One of the big benefits<\/strong> of Amplify was that CDN management<\/strong> was handled automatically internally<\/strong>. The CloudFront distribution, cache invalidation, and SSL integration are not manually provisioned or managed separately.<\/p>\n

          Why We Used S3-Based Deployment Instead of Git-Based Amplify<\/strong><\/h2>\n

          AWS Amplify makes it easy to deploy directly from GitHub, GitLab, BitBucket and AWS CodeCommit. But in our case, we deliberately employed S3-based deployments integrated with Jenkins pipelines.<\/p>\n

          This approach resulted in improved control of:<\/p>\n

            \n
          • Deployment to multiple environments<\/li>\n
          • Deployment of multiple accounts<\/li>\n
          • Deployment Permissions<\/li>\n
          • Custom CI \/ CD pipelines<\/li>\n
          • Managing Environment-Specific Configurations<\/li>\n<\/ul>\n

            Jenkins was already being used as the centralized CI\/CD platform so adding Amplify deployments to existing pipelines helped keep the consistency across environments.<\/p>\n

            \"text\"<\/p>\n

            \"test\"\"\"<\/p>\n

            Architecture Overview<\/strong><\/h2>\n

            The process for deployment is:<\/p>\n

              \n
            • Git repositories storing source code<\/li>\n
            • Jenkins Pipelines for CI\/CD Automation<\/li>\n
            • Artefact deployment to S3 buckets<\/li>\n
            • AWS Amplify for hosting the frontend<\/li>\n
            • Route53 for DNS management<\/li>\n
            • ACM for SSL certificates<\/li>\n<\/ul>\n

              \"test\"\"\"<\/p>\n

              Step 1: Jenkins for CI\/CD Automation<\/strong><\/h2>\n

              A Jenkins pipeline was configured to standardize deployments across environments.<\/p>\n

              pipeline processed:<\/p>\n

                \n
              • Git checkout<\/li>\n
              • getting environment config<\/li>\n
              • S3 sync for frontend build generation<\/li>\n
              • Scale deployment trigger<\/li>\n<\/ul>\n

                \"test\"\"\"<\/p>\n

                By automating this, we removed:<\/p>\n

                  \n
                • Manual deployment<\/li>\n
                • Deployment actions over SSH<\/li>\n
                • Manually clearing the cache<\/li>\n<\/ul>\n

                  \"test\"\"\"<\/p>\n

                  Step 2: Amplify Branches for Environment Management<\/strong><\/h2>\n

                  Dedicated Amplify branches were created for each environment to keep deployments isolated and easier to manage.<\/p>\n

                  Some examples are:<\/p>\n

                  QA UAT Production<\/p>\n

                  Each Amplify branch was a separate deployment environment, which made testing, validation, and release management easier.<\/p>\n

                  This was good for:<\/p>\n

                    \n
                  • Isolation of the environment<\/li>\n
                  • Independent releases of the front-end<\/li>\n
                  • Better deployment tracking<\/li>\n
                  • Optimized testing workflows<\/li>\n<\/ul>\n

                    \"test\"<\/p>\n

                    Step 3: Serving Frontend Artifacts with S3<\/strong><\/h2>\n

                    One of the biggest limitations we see with S3 deployments is that there is no environment variable management from the Amplify UI.<\/p>\n

                    To work around this, environment configurations were externally managed by using a single S3 configuration bucket.<\/p>\n

                    The configuration files required were pulled by Jenkins dynamically during deployment.<\/p>\n

                    For instance:<\/p>\n

                    aws s3 cp s3:\/\/config-bucket\/uat\/docker\/next-app\/.env .env<\/pre>\n
                    This improved:<\/p>\n
                      \n
                    • Configuration consistency<\/li>\n
                    • Security<\/li>\n
                    • Isolation of the environment<\/li>\n<\/ul>\n
                      Amplify deployments were triggered when frontend build artifacts were uploaded to Amazon S3.<\/p>\n
                      One behavior seen during Amplify deployments was that AWS Amplify would automatically change the S3 bucket policy to allow access to the deployment artifact path for the Amplify service.<\/p>\n
                      The Bucket policy allows the Amplify specific<\/code> branch to list and read objects only from the specific<\/code> prefix in the bucket. It also enforces secure HTTPS-only access to the bucket.<\/p>\n
                      This reduced the need to manually set up additional S3 access permissions for Amplify deployments.<\/p>\n
                      Using S3 also provided:<\/p>\n
                        \n
                      • Using S3 also provided:<\/li>\n
                      • Highly durable storage<\/li>\n
                      • Automatic scalability<\/li>\n
                      • Better cost optimization<\/li>\n
                      • High uptime<\/li>\n<\/ul>\n
                        Step 4: Deploying with AWS Amplify and managing CDN<\/strong><\/h2>\n
                        We set up custom domains using Route53 instead of the Amplify generated domains.<\/p>\n
                        The setup was as follows:<\/p>\n
                        .com domain names .net domain names<\/p>\n
                        Subdomains specific to the environment<\/p>\n
                        \"text\"<\/p>\n
                        \"\"When setting up custom domains, Amplify will automatically create the DNS entries for domain validation and CDN routing. These needed to be added to Route53.<\/p>\n
                        \"text\"<\/p>\n
                        We can use both for integrating SSL:<\/p>\n
                          \n
                        • Amplify-managed certificates<\/li>\n
                        • Custom ACM certs<\/li>\n<\/ul>\n
                          Now one thing:<\/p>\n
                          Amplify custom domains (ACM certificates) need to be in us-east-1 because Amplify uses CloudFront distributions internally.<\/p>\n
                          If certs are created in a different region, domain validation may still be in progress.<\/p>\n
                          \"txt\"<\/p>\n
                          \"tech\"<\/p>\n
                          Security Headers<\/strong><\/h2>\n
                          AWS Amplify also supports custom HTTP headers for additional frontend security and browser protection.<\/p>\n
                          Headers may be set either:<\/p>\n
                            \n
                          • Directly from the Amplify UI<\/li>\n
                          • Using customHttp.yml file<\/code><\/li>\n<\/ul>\n
                            Example configuration:<\/p>\n
                            customHeaders:\r\n- pattern: \"**\"\r\nheaders:\r\n- key: Strict-Transport-Security\r\nvalue: max-age=31536000; includeSubDomains\r\n- key: X-Frame-Options\r\nvalue: SAMEORIGIN\r\n- key: X-Content-Type-Options\r\nvalue: nosniff<\/pre>\n
                            \"\"<\/p>\n
                            Monitoring + Logs<\/strong><\/h2>\n
                            AWS Amplify also gave us out-of-the-box monitoring capabilities that included:<\/p>\n
                              \n
                            • Requests monitoring<\/li>\n
                            • Data transfer monitoring<\/li>\n
                            • 4xx and 5xx error tracking<\/li>\n
                            • Domain-wise access logs<\/li>\n<\/ul>\n
                              \"txt\"<\/p>\n
                              These logs were helpful for:<\/p>\n

                                Challenges and Limitations<\/strong><\/h2>\n
                                While implementing Amplify hosting and integrating it with a custom domain, we faced several practical issues.<\/p>\n
                                Route53 DNS Propagation Delays<\/strong><\/h3>\n
                                Incorrect DNS entries may continue propagating temporarily even after correction.<\/p>\n
                                To avoid unnecessary issues:<\/p>\n
                                  \n
                                • DNS records should be validated carefully<\/li>\n
                                • Multiple rapid retries should be avoided<\/li>\n
                                • Domain configurations should be performed gradually<\/li>\n<\/ul>\n
                                  \"text\"\"\"<\/p>\n
                                  ACM Certificate Region Restriction<\/strong><\/h3>\n
                                  A common issue occurred when ACM certificates were created outside us-east-1<\/code>.<\/p>\n
                                  Because Amplify internally uses CloudFront:<\/p>\n
                                    \n
                                  • Certificates must exist in us-east-1<\/code><\/li>\n
                                  • Otherwise SSL validation may remain pending<\/li>\n<\/ul>\n
                                    Limitations of S3-Based Deployments<\/strong><\/h3>\n
                                    With deployment workflows built around S3:<\/p>\n
                                      \n
                                    • Amplify UI does not support native environment variable management<\/li>\n
                                    • Configuration management must be done externally<\/li>\n<\/ul>\n
                                      This required centralized CI\/CD-driven configuration management using Jenkins and S3.<\/p>\n
