Case Study on Amazon SQS

What is Amazon SQS??

Amazon Simple Queue Service (SQS) is a managed message queuing service technical professionals and developers use to send, store and retrieve multiple messages of various sizes asynchronously.

The service enables users to decouple individual microservices, distributed systems and serverless applications from one another and to scale them without requiring the user to establish and maintain their own message queues.

Features of AWS SQS

The following features make AWS SQS a popular message management solution among developers:

• Durability: Amazon SQS relies on multiple servers to store your messages safely. Moreover, its Standard Queues & FIFO Queues operate on an at-least-once & exactly-once message delivery system.
• Availability: Amazon SQS leverages redundant infrastructure to generate high speed concurrent messaging. This way, it ensures that you experience an increased availability of messages for both production and consumption.
• Scalability: Amazon SQS offers you high scalability as it can independently process all the buffered message requests. Furthermore, it can scale transparently in sudden load spikes and does not need any prior instructions.
• Reliability: Amazon SQS uses a message locking mechanism during the processing phase. This allows multiple producers to send messages simultaneously to various consumers.

Benefits of using AWS SQS

1. Eliminate Administrative Overhead

AWS manages all in progress operations and underlying infrastructure required to produce an extremely accessible and scalable message queuing service.

With AWS SQS, there’s no direct value, no ought to acquire, install, and assemble messaging package, and no long build-out and maintenance of supporting infrastructure.

Amazon SQS queues are dynamically created and scale automatically, therefore, you’ll be able to build and grow applications quickly and with efficiency.

2. Reliably Deliver Messages

Use AWS SQS to transmit any volume of data, at any level of output, while not losing messages or requiring alternative services to be accessible. Amazon SQS helps you to decouple application parts in order that they run and fail severally, increasing the fault tolerance of the system.

Multiple copies of each message area unit hold on redundantly across multiple accessible zones in order that they’re out there whenever required.

3. Keep Sensitive Information Secure

You can use Amazon SQS to exchange sensitive data between applications using server-side secret writing (SSE) to inscribe every message body.

The AWS SQS compass point integration with AWS Key Management Service (KMS) permits you to centrally manage the keys that defend SQS messages together with keys that defend your alternative AWS resources.

AWS KMS logs each use of your encryption keys to AWS CloudTrail to assist meet your restrictive and compliance wants.

4. Scale Elastically and Cost-Effectively

AWS SQS leverages the AWS cloud to dynamically scale supported demand. Amazon SQS scales elastically together with your application. Therefore, you don’t have to worry regarding capability designing and pre-provisioning.

There’s no limit to the number of messages per queue, and commonplace queues offer nearly unlimited output. Prices area unit supported usage that provides important value saving versus the “always-on” model of self-managed electronic messaging middleware.

Case Study

redBus using AWS SQS

redBus is an Indian travel agency that specializes in bus travel throughout India by selling bus tickets throughout the country. Tickets are purchased through the company’s Website or through the Web services of its agents and partners. The company also offers software, on a Software as a Service (SaaS) basis, which gives bus operators the option of handling their own ticketing and managing their own inventories. To date, the company says they have sold over 30 million bus tickets and has more than 1750 bus operators using the software to manage their operations.

Challenge:

The company previously ran its operations from a traditional data center by purchasing and renting its systems and infrastructure. In addition to the expense, several logistical problems evolved from this arrangement. The biggest problem was that the infrastructure could not effectively handle processing fluctuations, which had a negative impact on productivity. Additionally, the procurement of servers or upgrading the server configuration was an extremely time-consuming endeavor. Over time, redBus realized that a better solution was imperative — a solution that offered scalability to handle the company’s processing fluctuations. redBus looked to Amazon Web Services (AWS) for a solution.

Benefits:

Since migrating to AWS, redBus has seen measurable improvements in the bottom line. Padmaraju says, “By scaling up and down dynamically based on the load, we maintain performance as well as minimize cost. With the time savings that the IT and development staffs obtain from the AWS solution, AWS gives us an overall cost benefit of about 30–40%.” He adds, “By hosting at [the AWS Asia Pacific (Singapore) region], redBus.in gained significantly in terms of website performance by way of reduced latency (about 4x). This is a great advantage when the customers are from India.”

Of the many excellent characteristics of AWS, perhaps the most significant to redBus is the ability to “instantly replicate the whole setup on demand for testing by creating and destroying instances on demand for experimentation, thereby reducing the time to market.” Less time to market translates to increased profitability and success.

The travel agency anticipates expanding the AWS solution to include Amazon Simple Notification Service (Amazon SNS) and Amazon Simple Queue Service (Amazon SQS) for monitoring, alerts, and intercommunication. “Amazon SQS is an especially good solution for enabling messaging between external applications and our applications,” says Padmaraju.

Since joining forces with AWS, redBus has gained the freedom to experiment on new solutions and applications at minimal cost, increased the efficiency of its operations, and improved its profitability.
