The ability to transmit messages of trust Amazon Simple Queue Service
Amazon Simple Queue Service (SQS) provides access to infrastructure architecture ensures messages are used by Amazon. You can perform sending and receiving of messages from anywhere using simple HTTP requests based on REST. No need to install anything, no need to configure anything. You can create an unlimited number of queues and send an unlimited amount of messages. The messages are stored by Amazon across multiple servers and data centers to provide redundancy capability and reliability you need from the messaging system. Each message can contain up to 8KB of text data. Only use Unicode characters with the following principles must comply
# x9 | #xA | #xD | [# X20 to # xD7FF] | [# XE000 to #xFFFD] | [# X10000 to # x10FFFF].
Each queue can have determined format timeout period (term-time), which is used to control access to the queue ways by many different readers. Each application reads a message from the queue, messages will not be read by any other readers until the timeout period ends. The message will be repeated in the queue after a timeout period is defined then it is held by a processor other readers.
SQS integrates very well with other Amazon Web Sercives. It provides a way to build a separate system where your EC2 can be exchanged with other systems by sending messages to SQS and coordinate the workflow. You can also use the queues for building a self-healing infrastructure, automatically expand based on EC2 for your applications. You can make sure the messages in your queue prevent unauthorized access by using authentication mechanisms provided by SQS.
Handling data sets with Amazon SimpleDB
Amazon SimpleDB (SDB) is the service Web allows storing, processing and query data sets structured. There is not a relational database according to the traditional approach where a higher level in the form of diagrams, with less structured data stored in the cloud and in which you can use to store and restore the key value. Each set of key values must have a name a single item; the items are divided into different domain each. Each entry can hold up to 256 key-value pairs of data. You can execute queries based on your data set in each different region. The query is based on each domain is not supported by SDB.

The server provides the type of single-core x86 to eight-core x86_64 kind. You can replace the case in the different geographic patterns or in the area where the spot to ensure the site can fail. Amazon also directed the concept of IP addresses change allows working with dynamic address. Amazon Simple Storage Service (S3) to provide Web services interfaces for storage and data recovery. Data given in any category and can be stored and accessed from any location via the Internet.
