Azure Virtual Machines vs. IBM PowerVM

If you want to host a dedicated Windows server on the cloud, and especially if you want to integrate it with your on premises Active Directory, Azure Virtual Machines should be your first choice. Obviously running Linux on Azure works very well too, but given Azure's pricing is not the cheapest, there are other providers out there that have a better cost-benefit ratio for Linux. That said, hosting Windows on Azure can be affordable (especially when compared to other providers) if you plan your licensing, topology, and application architecture correctly.

IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).

• When demand is high, we scale the service out, eg During a Football Match.
• When a football match is over and the throughput of data from OPTA drops we save by the service scaling back in.
• Our App Service Plans along with the Clean C# code are lightening fast giving a good customer experience.
• When producing the TV Guide information and a program overruns its scheduled time, a client can instantly be updated to the new programming schedule as our change is instant and its in the right place for all the clients to download and adjust their television guides appropriately to send out to the public giving a 24x7 uptime service that is precise and accurate and resilient to outages due to failover zones around the world.

• IBM PowerVM is used for virtualization on IBM Power series hardware to utilize the hardware resources more efficiently like micro partitioning for CPU, NPIV for fibre port...etc
• IBM PowerVM provides the feature of live partitioning mobility (LPM), which allows moving the running virtual machine from one hardware to another hardware without any disruption on a virtual machine.
• IBM Power VM provides the feature of Integrated virtual manager (IVM), which helps to manage the single IBM Power hardware. There is no need to purchase a separate hardware management console to manage the Power hardware. This works well for small organizations having small environments.

• Pricing can be a concern if you are truly agnostic to which cloud you are building your particular solution in.
• The UI, as is the case with any cloud provider, is crowded.
• As with any cloud provider, it can be difficult to tune in exactly the right amount of servers for your needs...you might find yourself under/overprovisioning.

• The ability to run Windows. Hardware architecture does not allow this, but it is a limiting factor.
• More performance monitoring and management could be built in.
• Sometimes is marketed and packaged in some rather unusual ways

The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.

No VM console, weak management interface, changing CPU/memory is not straightforward. On the positive side, basic RDP functionality is good to have. As long as things are working, the ability to host Windows VMs is appreciated.

Since it is built into the firmware (hardware) it requires no separate installation (except for the Virtual I/O servers, if you need those). Both HMC and Novalink (with PowerVC) support IBM PowerVM well and offer a user-friendly interface to setting up LPARs and making changes, most on the fly. Modern systems also give insights into performance, power consumption etc. A lot of separate tools exist to show more details, like LPAR2RRD, IBM Instana, IBM Turbonomic etc.

I give the overall support for Azure Virtual Machines a 7 because I think while the overall support do a great job there are still areas that it could improve on such as efficiency and speed. So while I only give it a 7 and it has some issues it is still better than the overall support at Amazon EC2 Auto Scaling.

Azure Virtual Machines offer unparalleled flexibility in provisioning, managing and upgrading the VM instances, both manually and programmatically. AVM offer very granular billing options and enables high costs optimisations (while still being costly). The other competitors I mentioned are very good at offering dead-cheap VMs. But if you need anything beyond that, especially for big computing, you need Azure Virtual Machines.

Our company utilizes VMware and PowerVM. VMware is very user friendly from an IT support view and makes supporting Windows OS easier. PowerVM is moving in that direction. PowerVM is better in that you can prioritize workloads across different VMs and be granular in your reservation of cores and virtual CPUs. PowerVM allows you to modify VM characteristics while the VM is up and running

• It's so easy to spin up new instances, that it becomes also to easy to have to many of them to manage. Many teams end up with a couple of hundreds of VMs after a short while, making the whole thing very hard to maneuver
• Azure VMs are the next step for us to rely on Onprem servers, and leaving the management of the infrastructure to the professionals
• The ease of use, is also important when our main focus is to deliver new applications and integrations fast, and not having to worry about infrastructure. We sell bottles, not CPUs

Incentivized

• We are able to run several LPARs on one frame, which means we do not need to buy as many physical servers. That saves on floor space, power, and heating and cooling of the data center, among other things.
• Using LPM allows us to do maintenance on a frame without impacting the LPARs, giving us greater uptime.
