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.
This is super exciting news. There are two features in particular that I am very excited to see in vSphere 6.5.
vSphere Integrated Containers – Run docker containers natively (well almost) on top of vSphere. VIC as it has been coined allows you to use the Docker API to spin up Docker containers inside a vSphere VM container. The vSphere VM container runs a super small version of PhotonOS that allows the container to run inside the VM container. This now allows you to run Docker containers with all the benefits of vSphere VM’s with the exception of NSX at the moment. However your containersa can take advantage of another new much anticipated feature.
vSphere Predictive DRS – Predictive DRS is a game-changing new technology that leverages self-learning and predictive analytics provided by vRealize Operations. It learns your environment and based on usage patterns, preemptively rebalances your workloads in advance of upcoming demands and spikes. This ensures your applications remain performant and your workloads get all the resources they need.
These aren’t the only exciting new features, but they are certainly two of my favorites. Among the other new features are:
- Scale Enhancements – New configuration maximums to support even the largest app environments
- VMware vCenter Server® Appliance – The single control center and core building block for vSphere
- vCenter Server® High Availability – Native vCenter Server high availability solution
- vCenter Server Backup and Restore – Native vCenter Server Backup and Restore
- vCenter Server Appliance Tool – Single step migration and upgrade of existing vCenter Server to vCenter Server Appliance
- REST APIs – Simple, modern developer-friendly APIs
- vSphere Client – HTML5-based GUI that ensures fast performance and cross-platform compatibility
- Security-at-Scale – Policy-driven security that makes securing infrastructure operationally simple
- Encryption – VM-level encryption protects unauthorized data access both at-rest and in-motion
- Audit-quality logging – Enhanced logging that provides forensic information about user actions
- Secure Boot – Protection for both the hypervisor and guest operating system by ensuring images have not been tampered with and preventing loading of unauthorized components
- Cross-Cloud vMotion® –Live migrate workloads between VMware based clouds ( Handy feature for the new Amazon and VMware partnership)
- Virtual Volumes™ Replication – Native array virtual volumes replication
