Amazon S3 on Outposts now delivers strong consistency automatically for all applications

Have you ever struggled with propagating updates between the different copies of replicated items while working on the cloud? If you have, I am pretty sure you’d like to know that you are not the only one who faces that problem. I have something for you that may help you in overcome that challenge comfortably!

Introduction about Amazon S3

If you are not acquainted with Amazon Simple Storage Service, it is an object storage service. You can count on it when it comes to gaining industry-leading scalability, data availability, security, and performance too. It’s quite remarkable how customers of various sizes and industries can use Amazon S3. It helps them to store and protect any amount of data for a range of use cases. Some of the most commonly involved use cases are data lakes, websites, mobile applications, backup and restore, archive, enterprise applications, etc. This platform looks after the provision of management features. With the help of that, you can seamlessly optimize, organize, and configure access to your data. It will help you meet your specific business, organizational, and compliance requirements easily and make things only more convenient for you.

Until this service was announced, organizations worldwide had a difficult time finding, storing, and managing all of your data. Apart from that, they faced problems related to running applications and delivering content to customers. Even hosting high-traffic websites, or backing up emails and other files required a lot of storage was quite difficult. Not just that, even the maintenance of the organization’s repository was expensive. It was time-consuming for several reasons.

This service is packed with loaded features for auditing and more. They help you with managing access to your buckets and objects. Talking about the default settings, Amazon S3 buckets and the objects in them are private. It means that you have access only to the S3 resources that you create. In order to grant granular resource permissions that support your specific use case of your Amazon S3 resources, all you have to do is use the features. You can do the same when it comes to auditing the permissions also. You can easily look after logging and monitoring tools. This service allows you to monitor and control how your Amazon S3 resources are being used.

Amazon S3 makes it easier for you to store data with changing or unknown access patterns in S3 Intelligent-Tiering. Intelligent-Tiering is known for optimizing storage costs. It does so by automatically moving your data between four access tiers. This process is triggered when your access patterns change.

Announcement Details

Amazon has recently announced that Amazon S3 on Outposts now delivers strong consistency automatically for all applications. What does it mean and why is it important? Let’s find out.

Importance of the Announcement

Following the announcement, Amazon S3 on Outposts now comes with the support of delivering strong read-after-write and list-after-write consistency. These abilities are compatible with any storage request and that too at no additional cost.

With the help of Amazon S3 on Outposts, you can seamlessly meet your low latency and local data processing. You can also look after the data residency needs simply by storing data on AWS Outposts.

By utilizing the S3 APIs and their excellent features, you can conveniently store, secure, tag, retrieve, report on, and even control access to data that is stored locally in S3 on Outposts buckets.

Much to your comfort, every request to S3 on Outposts storage is now strongly consistent. Following a successful writer of a new object, or even an overwrite of an existing object, any subsequent read request will be treated with the immediately received the latest object. The service will also fulfill your need to have strong consistency for list operations. It means that after a write, the service users can immediately perform a listing of the objects in a bucket. Not just that, all the changes will be effectively reflected.

If you have worked with analytics applications before, then you know that they often require access to an S3 object immediately after a write. If the consistency is weak, there are chances you would need to insert custom code into these applications. Even if that doesn’t work, you would need to provision databases in order to keep objects consistent with any changes in S3 across all objects. But after the announcement of these features, S3 on Outposts object APIs are strongly consistent. Even the applications that require access to an object immediately after a write have the ability to do so directly. And like a cherry on the top, no custom code is required.
