Amazon his week made enhancements and added features to its Amazon Simple Storage Service (S3) and its Amazon Aurora relational database. The S3 has been upgraded with more event notifications along with support for bucket-level Amazon CloudWatch metrics while Amazon Aurora now comes with zero-downtime migration.
Customers now can get notifications when an object has been deleted from an S3 bucket. The company launched its event notifications model last year, with support for when objects are created through Puts, Posts and Copy.
Amazon has been reducing prices on its cloud storage and added features such as reduced redundancy storage model, VPC endpoints and cross-region replication. The event notifications are its latest improvements.
“You can now arrange to be notified when an object has been deleted from an S3 bucket,” according to the AWS blog. “Like the other types of notifications, delete notifications can be delivered to an SQS queue or an SNS topic or used to invoke an AWS Lambda function. The notification indicates that a Delete operation has been performed on an object, and can be used to update any indexing or tracking data that you maintain for your S3 objects.”
The Amazon CloudWatch is designed to track metrics for AWS services and for customers’ applications. Customers now can monitor and set alarms on their S3 storage usage. The CloudWatch allows customers to set alarms to trigger when a metric reaches past a specified limit.
“Available metrics include total bytes (Standard and Reduced Redundancy Storage) and total number of objects, all on a per-bucket basis. You can find the metrics in the AWS Management Console,” according to the AWS blog.
Amazon also unveiled enhancements to its Amazon Aurora, which is designed for high performance and scales up to 64 TBs of storage. The Aurora is a MySQL database engine for Amazon. The database was launched last year and Amazon is enhancing the product based on customers’ input. Amazon has added zero-downtime migration to Aurora.
“Immediately after you migrate, you will begin to benefit from Amazon Aurora’s high throughput, security, and low cost,” according to the blog. “You will be in a position to spend less time thinking about the ins and outs of database scaling and administration, and more time to work on your application code.”
The Amazon Aurora also has been enhanced with replication capabilities. Each Amazon Aurora instance can have up to 15 replicas that add additional read capacity.
“It means that Amazon Aurora is able to handle far more concurrent queries (both read and write) than other products,” according to the blog. “Amazon Aurora’s unique, highly paralleled access to storage reduces contention for stored data and allows it to process queries in a highly efficient fashion.”
Amazon also is launching this in the East and West regions in North America and Europe regions, and intends to expand to other locations over time.
Amazon’s announcement comes on the heals of Google’s launch of its Google Cloud Storage Nearline archiving service, which is a sign that Google is making an aggressive run at AWS and Microsoft Azure. Google Cloud Storage Nearline currently is in beta and its low-cost archive cloud boasts a data-retrieval of three seconds, while Amazon Glacier has a restore time ranging from three hours to five hours.
