AWS SQS Standard vs FIFO Queue SQS offers two types of queues – Standard & FIFO queues SQS Standard vs FIFO Queue Features Message Order Standard queues provide best-effort ordering which ensures that messages are generally delivered in the same order as they are sent. Occasionally (because of the highly-distributed architecture that allows high throughput), […]
Kinesis Data Streams vs SQS Purpose Amazon Kinesis Data Streams allows real-time processing of streaming big data and the ability to read and replay records to multiple Amazon Kinesis Applications. Amazon Kinesis Client Library (KCL) delivers all records for a given partition key to the same record processor, making it easier to build multiple applications […]
AWS SQS Standard Queue SQS offers standard as the default queue type. Standard queues support at-least-once message delivery. However, occasionally (because of the highly distributed architecture that allows nearly unlimited throughput), more than one copy of a message might be delivered out of order. Standard queues support a nearly unlimited number of API calls per second, […]
SQS FIFO Queues provide exactly once delivery, prevents duplicates and preserves message order within the message group
Amazon SQS Features Visibility timeout defines the period where SQS blocks the visibility of the message and prevents other consuming components from receiving and processing that message. Dead-letter queues – DLQ helps source queues (Standard and FIFO) target messages that can’t be processed (consumed) successfully. DLQ Redrive policy specifies the source queue, the dead-letter queue, […]
SQS provides fully managed, reliable, highly-scalable, hosted queue for storing messages in transit between loosely couple applications and requires no administrative overhead and little configuration.
SQS is a temporary data repository for messages and provides a reliable, highly scalable, hosted message queuing service for temporary storage and delivery of short (up to 256 KB) text-based data messages. supports a virtually unlimited number of queues and supports unordered, at-least-once delivery of messages. Ideal Usage patterns is ideally suited to any scenario […]
RDS Multi-AZ vs Read Replica RDS DB instances replicas can be created in two ways Multi-AZ & Read Replica, which provide high availability, durability, and scalability to RDS. Purpose Multi-AZ DB Instance deployments provide high availability, durability, and automatic failover support. Read replicas enable increased scalability and database availability in the case of an AZ […]
RDS Read Replicas RDS Read Replica is a read-only copy of the DB instance. RDS Read Replicas provide enhanced performance and durability for RDS. RDS Read Replicas allow elastic scaling beyond the capacity constraints of a single DB instance for read-heavy database workloads. RDS Read replicas enable increased scalability and database availability in the case […]
DynamoDB with VPC Endpoints By default, communications to and from DynamoDB use the HTTPS protocol, which protects network traffic by using SSL/TLS encryption. A VPC endpoint for DynamoDB enables EC2 instances in the VPC to use their private IP addresses to access DynamoDB with no exposure to the public internet. Traffic between the VPC and the […]
