Jane (Interviewer): Thanks for coming, Peter.
Peter (Interviewee): Thanks for having me, Jane.
Jane: Let's start with AWS. What's the purpose of AWS SQS?
Peter: SQS is designed for message queuing, which means it is used to decouple and scale microservices, distributed systems, and serverless applications by allowing messages to be sent and received asynchronously.
Jane: How long are those messages retained? Is this configurable?
Peter: Messages in SQS are retained for up to 14 days. The retention period is configurable and can be set from a minimum of 1 minute to a maximum of 14 days.
Jane: Is it possible to scale that?
Peter: Yes, SQS scales automatically to handle large numbers of messages and high-throughput workloads. This means it can dynamically adjust to accommodate increased traffic and message volumes, allowing applications to process messages at their own pace.
Jane: How does SQS handle errors in message processing?
Peter: SQS provides a feature called Dead-Letter Queues (DLQs) for handling errors in message processing. If a message fails to be processed successfully after a specified number of attempts, it can be moved to a DLQ. This allows for further inspection and troubleshooting of problematic messages without affecting the processing of other messages in the main queue.
Vocabulary Section
Asynchronously

Sample Sentences:
The application handles requests asynchronously to improve performance and responsiveness.
Asynchronously processing data helps in managing multiple tasks efficiently.
Portuguese Translation: Assíncrono
High-throughput Workloads
Definition: Refers to tasks or processes that involve handling a large volume of data or requests within a given timeframe.
Sample Sentences:
The system is optimized to handle high-throughput workloads, ensuring smooth operation during peak times.
Managing high-throughput workloads requires robust infrastructure and efficient processing techniques.
Portuguese Translation: Alta capacidade
Accommodate
Definition: To adjust or adapt to fit the needs or requirements of something.
Sample Sentences:
The system can accommodate increasing amounts of data as demand grows.
We need to upgrade the server to better accommodate high traffic volumes.
Portuguese Translation: Acomodar
Troubleshooting
Definition: The process of diagnosing and resolving problems or issues that arise in a system or process.
Sample Sentences:
Effective troubleshooting is essential for maintaining system reliability and performance.
The IT team is troubleshooting the network issue to restore connectivity.
Portuguese Translation: Solução de problemas
At Their Own Pace
Definition: Refers to performing tasks or processing at a speed that suits the individual or system, without being rushed or constrained by external factors.
Sample Sentences:
Employees can complete their tasks at their own pace, allowing for better quality work.
The application allows users to process data at their own pace, avoiding bottlenecks.
Portuguese Translation: No seu próprio ritmo
Message Queuing
Definition: A method of communication in which messages are placed in a queue and processed asynchronously, allowing for decoupling of different system components.
Sample Sentences:
Message queuing helps in managing and processing messages between distributed systems efficiently.
By using message queuing, the system can handle incoming requests without immediate processing.
Portuguese Translation: Fila de mensagens
Decouple
Definition: To separate or disconnect components or systems so that they operate independently of each other.
Sample Sentences:
Decoupling services in the application allows for easier maintenance and scalability.
The microservices architecture helps to decouple different parts of the system.
Portuguese Translation: Desacoplar
Up To
Definition: Indicates the maximum limit or extent of something.
Sample Sentences:
The retention period for messages in SQS can be configured up to 14 days.
The system is capable of handling up to 1,000 concurrent users.
Portuguese Translation: Até
Configurable
Definition: Able to be adjusted or set according to specific requirements or preferences.
Sample Sentences:
The retention settings in SQS are configurable to meet different business needs.
We need a configurable solution to adapt to various user requirements.
Portuguese Translation: Configurável
Number of Attempts
Definition: Refers to the count of times an action or operation is tried or executed before achieving success or failure.
Sample Sentences:
The system will retry the message delivery a certain number of attempts before moving it to the Dead-Letter Queue.
The number of attempts can be configured to handle retries according to specific needs.
Portuguese Translation: Número de tentativas
Message Volume
Definition: The amount or quantity of messages being processed or handled within a given period.
Sample Sentences:
The application can manage high message volume during peak hours without issues.
We need to optimize the system to handle increased message volume efficiently.
Portuguese Translation: Volume de mensagens
Dead-Letter Queues
Definition: Specialized queues used to handle messages that cannot be processed successfully after a specified number of attempts.
Sample Sentences:
Dead-Letter Queues are used to store failed messages for further analysis and troubleshooting.
By configuring Dead-Letter Queues, you can ensure that problematic messages do not block the processing of others.
Portuguese Translation: Fila de mensagens mortas
Sample sentences
Asynchronously
The web application processes user requests asynchronously to ensure a smooth user experience.
By handling tasks asynchronously, the system avoids blocking operations and improves overall efficiency.
High-throughput Workloads
The database was optimized to handle high-throughput workloads during the company's busiest periods.
To support high-throughput workloads, the infrastructure was upgraded to include additional servers and storage.
Accommodate
The new software update was designed to accommodate the increasing number of users and data requests.
The server configuration needs to be adjusted to accommodate the new high-performance requirements.
Troubleshooting
The IT team conducted troubleshooting to identify and resolve the network connectivity issues affecting the office.
Effective troubleshooting techniques are essential for minimizing downtime and maintaining system reliability.
At Their Own Pace
Employees can complete training modules at their own pace, allowing them to fit learning into their schedules.
The software allows users to process their data at their own pace, preventing bottlenecks and enhancing productivity.
Message Queuing
Message queuing systems are essential for managing communication between different services in a distributed application.
Using message queuing helps to ensure that messages are processed in the order they are received, even under heavy load.
Decouple
By decoupling the front-end and back-end services, the development team could work on features independently and more efficiently.
Decoupling the data storage from the application logic allows for easier scaling and maintenance of the system.
Up To
The service can handle up to 10,000 requests per second, ensuring it meets high-demand scenarios.
The software's subscription plan allows users to store up to 100GB of data before requiring an upgrade.
Configurable
The system’s alert settings are highly configurable, allowing users to customize notifications based on their preferences.
Configurable parameters in the application help to tailor performance and functionality to specific use cases.
Number of Attempts
If the message fails to be processed after the specified number of attempts, it will be moved to a Dead-Letter Queue.
The retry logic in the system is designed to handle up to five attempts before flagging the request as failed.
Message Volume
The server was scaled to handle the increased message volume during the product launch event.
We need to monitor the message volume closely to ensure the system can manage peak periods effectively.
Dead-Letter Queues
Messages that cannot be processed successfully are moved to Dead-Letter Queues for further inspection and resolution.
Implementing Dead-Letter Queues helps in managing errors and prevents issues from affecting the processing of other messages.
