What types of servers are used to send messages within Amazon SQS?
- Requesting server/worker server.
- Alternating server/planner server.
- Performance server/slacker server.
- Available server/negative server.
Which Amazon service can you use in conjunction with SQS to fan out SQS messages to multiple queues?
15 You can use SNS in conjunction with SQS to fan a single message out to multiple SQS queues. 16 Unlike Cloud Formation, the use of Elastic Beanstalk is not free.
When using Amazon SQS how much data can you store in a message?
SQS messages have a maximum storage size of 256 kb.
Why do we use Amazon SQS?
Use Amazon SQS to transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be available. SQS lets you decouple application components so that they run and fail independently, increasing the overall fault tolerance of the system.
How buffer is used in Amazon Web Services?
Buffer helps to synchronize different components, which gets requests and processes it in an unsynchronized way. It manages the balance between various components in order to maintain the speed and provide a faster service. In AWS buffer also ensures efficiency over traffic or load.
Can SQS have multiple consumers?
You can have multiple consumers, but you have to remember that each message can be processed only once. It means that you can have multiple instances of the same consumer, but you can’t read the same message from one queue in two different components. Each of these components should use a separate SQS queue.

Reliability – Amazon SQS locks your messages during processing, so that multiple producers can send and multiple consumers can receive messages at the same time. Customization – Your queues don’t have to be exactly alike—for example, you can set a default delay on a queue.
How do I use Amazon SQS with AWS KMS?
You can use Amazon SQS to exchange sensitive data between applications using server-side encryption (SSE) to encrypt each message body. Amazon SQS SSE integration with AWS Key Management Service (KMS) allows you to centrally manage the keys that protect SQS messages along with keys that protect your other AWS resources.
How does Amazon SQS keep track of the message deduplication ID?
Amazon SQS continues to keep track of the message deduplication ID even after the message is received and deleted. The producer should provide message deduplication ID values for each message in the following scenarios:
