Discovering AWS: Application Services

Simple Workflow Service (SWF)

It is a task coordinator and state management service for your applications in the Cloud. It has Deciders and Workers that we could configure as we need. SWF ensures tasks are executed in a reliable way, in order and without duplicate them. Deciders and Workers run in your infrastructure and SWF manage the state.

 CloudSearch

It is a fully-managed service that makes it easy to set up, manage, and scale a search solution for your website or application in the Cloud. It integrates a quick search and highly scalable functionality in your application. It escalates automatically. With a few clicks in the AWS Management Console, you can create a search domain, upload the data you want to make searchable to Amazon CloudSearch, and the search service automatically provisions the required technology resources and deploys a highly tuned search index. As your volume of data and traffic fluctuates, it seamlessly scales to meet your needs. You can easily change your search parameters, fine tune search relevance, and apply new settings at any time without having to re-upload your data.

Simple Notification Service (SNS)

It creates, operate and sent notifications. Publish a message from an application and distribute it immediately to all subscribers or to other applications. It includes now a Mobile Push Messaging service that enables you to push to mobile devices such as iPhone, iPad, Android, Kindle Fire and internet connected smart devices. It can also deliver notifications by SMS text message or email, to Amazon Simple Queue Service (SQS) queues, or to any HTTP endpoint.

 Simple Queue Service (SQS)

It is a fast, reliable, scalable, fully managed message queuing service. You can use SQS to transmit any volume of data, at any level of throughput, without losing messages or requiring other services to be always available. To prevent messages from being lost or becoming unavailable, all messages are stored redundantly across multiple servers and data centers.  Developers can get started with SQS by using only five APIs: CreateQueue, SendMessage, ReceiveMessage, ChangeMessageVisibility, and DeleteMessage. Additional APIs are available to provide advanced functionality.

 Simple Email Service (SES)

It is a bulk and transactional email-sending service. You can send transactional email, marketing messages, or any other type of high-quality content and you only pay for what you use. In the Cloud, servers can changes, IP addresses can changes (especially if you use AutoScaling) so a server can’t send mails itself. It needs to use SES to send mails. Important thing: this is not a spam tool.

 Elastic Transcoder

It is media transcoding in the cloud. It is designed to be a highly scalable, easy to use and a cost effective way for developers and businesses to convert (or “transcode”) media files from their source format into versions that will playback on devices like smartphones, tablets and PCs. It can be used for audio and video transcoding.

Amazon CloudFront

Amazon CloudFront is a content delivery web service. It integrates with other Amazon Web Services to give developers and businesses an easy way to distribute content to end users with low latency, high data transfer speeds, and no commitments. It is basically a Content Delivery Network (CDN) like Akamai. It supports video streaming and live streaming with Adobe FMS.
