# Amazon SQS collects and organizes aws sqs documents and uses Ruby demos
# Amazon simple Queue Service (SQS) is a scalable and reliable message delivery framework that allows you to easily create, store, and retrieve text messages. You can use it to build Amazon Web Services-based applications. Using
First, SNS = simple Notification Service,sqs = simple Queue ServiceWhat is the difference between SNS and SQS?(REF:HTTPS://STACKOVERFLOW.COM/QUESTIONS/13681213/WHAT-IS-THE-DIFFERENCE-BETWEEN-AMAZON-SNS-AND-AMAZON-SQS)SNS is a distributed publish-subscribe system, and once publisher publishes it, subscriber can receive it immediately .The SNS Subscriber (end point
redundant architecture provides extremely high availability for concurrent access. It also ensures message delivery (at least once ).
You must pay only based on your usage. For Amazon SQS, this means you pay $0.000001 for each message. AWS currently provides a free tier, with the first 100,000 messages per month beingFree. Remember that bandwidth fees are priced at gigabytes, which is common to all
SQS is the simple queue service, which is a distributed Message Queue Service. It is very simple to use. The Message Queue Service can be used for buffer burst, so that the entire service can be processed asynchronously and components are not always available. When using Amazon SQS, developers only need to use five APIs: Createqueue, sendmessage, receivemessage, changemessagevisibility, and deletemessage.

Designing highly available applications is an important goal of architects. However, Designing highly available applications based on cloud computing platforms is different from designing traditional platforms. When cloud computing brings many new design challenges to architects, it also brings many new design concepts and available services. How to make full use of the features of the cloud platform when designing applications is an important condition for cloud computing-based design. In this

While AWS's limited preview service in China (Beijing) region was being launched, many customers demanded AWS Support. When AWS customers deploy systems to the cloud, daily operation and maintenance, and key project implementation, they need to quickly respond, customize on demand, and provide professional and trusted cloud technical support services at different levels.

Just put, it was two years ago that I used AWS for the first time. This was two years since the rapid development of cloud computing and big data technologies. During this period, the freetier instance has been running for nearly a year and will immediately enter the billing cycle. Although I have used a piece of aliyun product in the middle (A Lot Of Money), and now I contribute $5 to digitalocean every month, only

AWS provides a wide variety of mirrors for users, but in most cases the AMI provided in the community do not fully meet our needs, such as the more disgusting some mirrored root partitions are only 10g, so we generally use the community's public image to create a EC2, And then configure her, and then hit a mirror for the project, Packer can make us more automated to generate AMI, we can write the original image and all the configuration of the content
