Use Amazon CloudWatch to monitor your workload and get insights into performance so that your application runs and responds effectively. Complement this with Step Functions to orchestrate your serverless workflow, handle errors automatically, and maintain consistency in processing. These services give you the observability and control you need to proactively identify and resolve issues.

Utilize Cognito to authenticate users and authorize access to your resources. Pair this with CloudFront to securely deliver your content globally, with built-in distributed denial-of-service (DDoS) protection from AWS Shield Standard. These services ensure only valid users can access your application while safeguarding your data.

Amazon S3 stores your videos, images, and other media objects with high availability and durability, minimizing the risk of data loss or downtime. It also supports features like versioning, cross-Region replication, and lifecycle policies, contributing to the integrity and availability of your data. Use this with CloudWatch to monitor your application and automatically respond to incidents when thresholds are breached. Finally, use Step Functions to orchestrate your serverless workflows, with built-in error handling and retry mechanisms that support consistent processing and fault tolerance.

Optimize your application's performance by taking advantage of serverless computing with Lambda. You can use this in tandem with Amazon Bedrock for high-performing machine learning inference, and benefit from the global reach of CloudFront to deliver content with low latency. These services work together to scale your application efficiently and deliver a responsive user experience.

Optimize costs by using Amazon S3 Intelligent-Tiering and Amazon S3 Lifecycle configuration to automatically store your media in the most cost-effective manner. Amazon S3 Lifecycle transitions files to cheaper storage tiers or deletes them based on rules, keeping your costs low. Lambda and Amazon Bedrock also help, as you only pay for the resources you use without provisioning servers. Lambda scales on demand, charging only for compute time used, and Amazon Bedrock is invoked as needed, avoiding idle infrastructure costs.

Lambda scales dynamically based on demand, improving efficiency and eliminating constant server provisioning. It also supports event filtering for Amazon SQS to reduce traffic to your Lambda functions. Complement this with Amazon S3 Intelligent-Tiering and Amazon S3 Lifecycle, which automatically shift data to the most suitable storage tiers based on usage. This minimizes expensive storage and unnecessary data. Finally, CloudFront caches content closer to users, lowering network traffic and energy consumption for data transfers.
