Understanding of SES-SQS
-The full form of AWS SES is Simple Email Services.
-To send email with SES is too easy and straightforward.
-To prevent spamming by default its only provides us a sandbox environment.
-In free tier (sandbox) account, you can send and receive emails from verified email addresses only.
-Please find below steps to configuration with screenshot.
– You can send simple text email or email with specific template.
– We are using Node AWS SDK to show you sample code to send email with AWS SES and NodeJs.
Installation
– npm install node-ses
Small example
var ses = require(‘node-ses’);
let client = ses.createClient({ key: ‘key’, secret: ‘secret’ });
// Give SES the details and let it construct the message for you.
client.sendEmail({
to: ‘Email Address’
, from: Email Address’
, cc: ‘Email Address’
, bcc: [‘ Email Address’, ‘ Email Address’’]
, subject: ‘AWS SES TEST EMAIL’
, message: ‘your <b>message</b> goes here’
, altText: ‘plain text’
}, function (err, data, res) {
});
//OR use sendRawEmail
client.sendRawEmail({
, from: ‘somewhereOverTheR@inbow.com’
, rawMessage: rawMessage
}, function (err, data, res) {
// …
});

SQS(Simple Queue Service)
– The full form of SQS is Simple Queue Service.
– SQS is used to send, store, and receive messages between software components, without losing messages or its not requiring other services to be available.
– Queuing service enables you to decouple and scale distributed systems, microservices and serverless applications.
Benefits
- ELIMINATE ADMINISTRATIVE OVERHEAD
- RELIABLY DELIVER MESSAGES
- KEEP SENSITIVE DATA SECURE
- SCALE ELASTICALLY AND COST-EFFECTIVELY
Types of que
-Standard Queue
– FIFO Queue
Standard Queue
– TPS(Transaction Per Limit) is nearly unlimited.
– Message will be delivered at least once, occasionally it might be delivered in an order different from which they were sent.
– Send data between applications when the throughput is important, for example:
- It will decouple live user requests from intensive background work: let users upload media while resizing or encoding it.
- Allocate tasks to multiple worker nodes: process a high number of credit card validation requests.
- Batch messages for future processing: schedule multiple entries to be added to a database.
FIFO Queue
– This type of queues support up to 300 messages per second (receive, send or delete).
– When you batch 10 messages per operation (maximum), FIFO queues can support up to 3,000 messages per second.
– You can raise a support request to increase limit.
– The order is strictly preserved to messages sent and receive.
– Once message is delivered remains available until a consumer process and deletes it.
– Send data between applications when the order of events is important, for example:
- Need ensure that commands are executed in the right order.
- Display the correct product price by sending price modifications in the right order.
- Prevent a student from enrolling in a course before registering for an account.
