It’s no secret that this is a feature that I’m very excited about. This feature although very useful on it’s own is going to open up the door for many new exciting capabilities with out VMware products in the future.
Resource contention is one of the most critical issues in any virtualized environment. When contention occurs, applications slow down and your users are affected. Up until now two different methodologies have been employed to mitigate the risk of contention, with varied results. But now I want to introduce you to the new “game changing” method available from VMware: Predictive DRS! But first a bit of a history lesson on the original two methods.
The first of these is the Reactive Method which focuses on resolving unexpected resource demand. The most widely used example of a reactive solution is VMware’s Distributed Resource Scheduler, or DRS. As the day progresses, workloads may need more resources, which can lead to contention on the host. The reactive method moves VMs around to ensure all workloads get the resources they need and applications remain healthy. Note this method needs only a minimal amount of VMs to be moved in order to be effective, which means minimal overhead. The reactive method only moves VMs when contention approaches, so it’s possible (however remote) for users to feel some effects of the contention before it’s resolved.
Learn more about the other methods available with predictive DRS in the original article on VMware Cloud Management blog site.
Many of you may have already seen the news, but I like to create a roll up to make it easy to see what’s been newly released. Yesterday Tuesday August 23rd 2016 VMware released a number of much awaited Management product updates. See below for a breakdown of the updates per product.
vRealize Automation 7.1
vRealize Automation 7.1 is optimized for growing clouds thanks to significant improvements in the automated installation experience.
vRealize Automation 7.1 continue simplifying the primarily and secondary setup process by adding ability to automate the setup process among similar deployments leveraging the new Silent Installer. Cloud Admins are now able to scale out existing vRealize deployment by adding more vRA components and manage them automatically though the new Command Line(CLI) interface.
vRA 7.1 release is also equipped with a brand new Migration tool which allows you to perform safe and sound side by side upgrade (migration) existing vRealize Automation systems 6.2.X to the latest and greatest release. During the migration process the source production environment remains intact which guarantees a minimum downtime of the production environment.
Over the weekend Roman, Grant, John and I released a significant update to the platypus project, which is essentially a very simple and elegant way to provide a Swagger based documentation of several VMware Products. This project started out by providing a quick way to consume the vRealize Automation 7 API, but it has grown a healthy set of legs.
