Why We Chose AWS S3 for Storing Interview Conversation Audio While Building Recroo AI

Building Recroo AI, an end-to-end AI interviewing platform, required several critical decisions regarding interview conversation audio storage. We did a decent amount of homework in this regard through research and deliberation, after which we zeroed in on AWS S3 as our primary solution for storage. Here's why.

Scalability

AWS S3 stands for Simple Storage Service, and in terms of scalability, it's internationally recognized. As the growth continues at Recroo AI, its audio data increases geometrically. Therefore, the close-to-unlimited storage offered by AWS S3 means that this kind of growth is not going to be a problem, with no questions of reaching the storage limit or degraded performance.

Durability and Reliability

One has to be very sure of the durability of the data, especially when the information in the interviews is of a critical nature. AWS S3 offers very strong durability of 99.999999999%, which is literally going to keep our audio files quite safe. This durability is attained through automated replication across numerous data centers that are geographically dispersed, hence reducing the possibility of loss.

Security

Security is an area of huge concern, especially for institutions that deal with handling sensitive interview data. The following are brilliant security features of AWS S3:

• Encryption: S3 offers both server-side and client-side encryption. It provides end-to-end security by ensuring that data is encrypted in transit and at rest.

• Access Control: Fine-grained access control policies allow the specification of who can access and manipulate our data.

• Audit Logs: Detailed logging of all requests against S3 is done in AWS CloudTrail to ensure complete transparency and accountability.

Cost Effectiveness

One of the very first considerations in this startup is cost management. AWS S3 has one of the best, if not the best, scalable pricing models in the market today. We only pay for what we store, and for their other storage classes, cost-optimized approaches can be pursued depending on how frequently data will be accessed and by any other requirements around a data lifecycle.

Integration with Other AWS Services

Another principal advantage of AWS S3 is the convenience of integration with many other services offered by AWS. For example, the processing of audio files in real-time is significantly helped by AWS Lambda. For instance, it will transcribe the audio into text or analyze what was discussed during the interview. AWS Transcribe will turn audio interviews into text for further analysis.

• AWS CloudFront: Distributes our content with high availability, low latency, and high transfer speed for a good user experience.

Global Reach

AWS has a vast infrastructure laid all over the world, and S3 is spread across many regions. This allows us to store data closer to customers, avoiding latency and thus providing better access times. It also helps ensure that appropriate compliance regarding data residency requirements is maintained—something of real importance in international operations.

Simplified Management

Managing huge volumes of data can become totally impossible, but AWS S3 does this with features like versioning, lifecycle policies, and cross-region replication. All of these create automation for tasks involved in management, reducing the load on the operations team. For example, archiving old audio files or keeping multiple versions of an interview means less operational overhead on our side.
