Hello, Cloud Gurus and welcome to another episode of AWS this week, where we process the going ons of the last week to bring you only the finest in AWS news. This week, we'll be covering Amazon OpenSearch can now search across regions, AWS cost allocation tags now have API support, EC2 introduces the new R6id instance type, and a brief about some of the upcoming AWS events. Amazon OpenSearch now supports cross-region searches. OpenSearch's previously supported the ability to search across domains within the same region. But this comes with some limitations in practice. Many companies will deploy their resources, including OpenSearch clusters, across different regions, to meet architectural requirements such as data sovereignty.

This new feature enables cross cluster searching for both OpenSearch and versions of ElasticSearch after 7.10. Now beyond the version restrictions, there are a couple of limitations to be aware of, most notably that you can't mix and match domains running OpenSearch and ElasticSearch, and that you can't use this feature with any self-managed clusters, just due to how the feature operates. There are some more limitations to be aware of, but they are well covered in the AWS documentation. If you're using OpenSearch within your organization, especially across regions, this might just make your life a little bit easier. Cost allocation tags are a super important part of managing our costs in AWS, especially in large enterprises where we need to be able to apportion the costs of resources to individual departments often at enormous scales.

But what doesn't scale quite so well is managing those cost allocation tags. After you've decided on the tags you want to use up until now, you've had to log into the AWS management console and activate each tag in the billing console with multiple AWS accounts, you may need to perform this multiple times. With this release, AWS have made it possible to manage your cost allocation tags through the AWS API, including its various SDKs and the command line. If you're managing a large AWS organization with complex cost allocations, this gives you the opportunities to better manage these tags and remove some of those headaches with this feature. Now being available in all regions. A new family of EC2 instances have entered general availability with new memory optimized R6id instances.

Running the same Intel Xeon processors as the rest of the R6i family, the new R6ids also include a huge amount of local NVme SSD storage. Compared with the previous R5d series, you're paying about 5% more for on demand, but with the substantial boost in the relative amount of instant storage available and performance for both the networking interface and for the EBS storage as well. It's fair to call out that the R6GD instance family, powered by AWS's ARM based graviton2 processors are still available, and at up to 24% lower on demand costs than the new Intel Xeon powered R6id counterparts. To do this though your workload wouldn't need to be able to run on an ARM based processor, and for this reason, you may find it better using these new R6id instances with their X86-64 architecture. So if you're pushing the limits of instance storage in your current configuration, this may help you scale more effectively.

The R6ids are currently available in the north Virginia, Ohio, Oregon, and Ireland regions, with more to follow. AWS are hosting a number of events over the next few weeks, which kicks off this week with Amazon re:Mars. Re:Mars is a conference in Las Vegas, bringing together many of the biggest minds in machine learning, automation, robotics, and space technologies. Sessions are covering everything from using AI for clinical medicine, managing fleets of autonomous vehicles, and measuring carbon emissions using satellites and machine learning. So attendees really are in for a treat. If you're interested,

you can also watch the keynote talks online through the livestream. Beyond this, AWS Summits are also kicking off this week in Milan and Toronto, continuing to circle the globe. These are great opportunities to connect with your local tech community and spend the day immersed in learning more about AWS. For a full list of locations and dates and further information, check the resources in the description of this video. That's it for the news this week. We hope you've enjoyed it.
