It's the little things that matter in Amazon Redshift upgrade

The company has improved its data warehouse service for the third time this year

Amazon Web Services has increased the number of simultaneous queries its hosted data warehouse Redshift can handle, improving performance in cases where many small queries are now forced to wait.

Amazon contends that Redshift lowers the bar for implementing and managing a data warehouse. The company provisions the infrastructure and tasks such as backups and patching are automated.

The latest upgrade lets users execute up to 50 queries at the same time, compared to a maximum of 15 before.

The ability to execute more queries is useful when a data warehouse has to handle lots of small queries. A queue that is configured to handle many queries has less memory for each one, but that is offset by the fact that smaller queries require less memory, according to Amazon.

Users can speed up transfers from Amazon's Hadoop-based Elastic MapReduce clusters by loading data in parallel.

Redshift data warehouses are made up of clusters of so-called Dense Storage nodes or Dense Compute nodes. The storage nodes allow enterprises to build very large data warehouses using hard disk drives for a low price per gigabyte, while the compute nodes let enterprises configure high-performance data warehouses using faster CPUs, large amounts of RAM and SSD storage.(The compute nodes are ideal for enterprises which have less than 500GB of data in their warehouse or whose primary focus is performance. The storage nodes are a better fit when performance isn't as critical and storage demands are high but the budget isn't, according to Amazon.

The storage nodes cost from US$0.850 per hour and the cheapest compute node is priced at $0.250 per hour.

The compute nodes were announced in January; in February Redshift was integrated with CloudFormation, which lets developers and systems administrators create and manage a collection of related resources.

Among competitors to Amazon Redshift are Microsoft, which lets enterprises run a customized version of SQL Server for data warehousing on Azure. The customization is based on the company's Fast Track reference hardware configurations for on-premise installations.

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
