Amazon RDS Performance Insights Supports Counter Metrics for Aurora PostgreSQL

By

Amazon RDS Performance Insights, an advanced database performance monitoring feature, now supports additional counter metrics on Amazon Aurora with PostgreSQL compatibility. With counter metrics, you can customize the Performance Insights dashboard to include up to 10 additional graphs that show a selection of dozens of operating system and database performance metrics. This information can be correlated with database load to help identify and analyze performance problems.

New AWS ParallelCluster Features

By

Three new features for AWS ParallelCluster, available today, will help customers further simplify the process of creating and managing HPC clusters on Amazon Web Services (AWS).

AWS Batch Support: Customers can now use AWS Batch as a job scheduler in AWS ParallelCluster and submit distributed computing jobs through AWS ParallelCluster to AWS Batch. AWS Batch enables developers, scientists, and engineers to easily and efficiently run hundreds of thousands of batch computing jobs on AWS. AWS Batch also supports scheduling multi-node parallel jobs, enabling customers to efficiently run single jobs that span multiple Amazon EC2 instances.

Amazon Elastic File System (EFS) integration: AWS ParallelCluster now supports native configuration for EFS to further enhance storage and file management features. Users can create and/or mount EFS directly from AWS ParallelCluster without a post-install script.

RAID Array Configuration Support: AWS ParallelCluster customers can now easily create a RAID 0 or RAID 1 array for use with their HPC cluster. RAID 0 combines multiple drives into a single drive to provide enhanced I/O performance, while RAID 1 combines multiple drives into a single drive for better fault tolerance. RAID arrays can be created from up to 5 Amazon Elastic Block Store (EBS) volumes.

AWS ParallelCluster is available at no additional charge, and you pay only for the AWS resources needed to run your applications. AWS ParallelCluster is released via the Python Package Index (PyPI). AWS ParallelCluster’s source code is hosted under the Amazon Web Services repository on GitHub .  Learn how to launch an HPC cluster using AWS ParallelCluster here .

New AWS Direct Connect locations in Silicon Valley and Stockholm

By

AWS Direct Connect is now live at two new locations in Silicon Valley and Stockholm. In Silicon Valley, AWS Direct Connect launched its third location at CoreSite SV2, Milpitas. This location is the first new location that offers logical redundancy over a single virtual interface (VIF) on a Direct Connect connection, a new capability launched last month. Logical redundancy can reduce downtime when a BGP peering session goes down due to a device failure or maintenance activity on the AWS side. CoreSite SV2, Milpitas can be found under its associated home region of US West (N. California). With Direct Connect Gateway and global public VIFs, customers can access their resources in any global AWS Region (except China).

Failed Space-X re-entry is a control triumph

By

Space-X’ launcher recovery recently failed, in a way that a friend pointed out showed a triumph of automated control. Famously, Space-X Falcon 9 booster stages bring themselves back from space and land in one piece ready to be used again, and again. However, CRS-16 last week had a problem on the way back – a hydraulic …

If a motor driver was ever made for Arduino and battery power

By

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB and 4xAA cells all covers, but sadly not 7.2V remote-control model battery packs. It is an …

3D printing a fan duct, and ‘blend’ in DesignSpark Mechanical

By

RS Component’s DesignSpark Mechanical v4 couldn’t have come at a better time as I my fledgling knowledge of 3D printing had just extended to understanding that my cheap 2nd-hand printer needed a bit more cooling to make the printing filament set quicker – known as ‘part cooling’. The cooling duct on the right does not …
