Rather the cost of vSphere is due to its value. When you buy vSphere you get value that has grown over the years, and in fact will continue to grow. It is not a tax since you do not have to buy vSphere. But if you want the value of vSphere you need to pay for it.
I have started to hear a lot of people talk about how the cost to vSphere is a tax. Here is a list of things I think is the value of vSphere and why it is worth paying for.
- Distributed Resource Scheduler (DRS) – this has two components – the initial placement means when a VM is powered up, it is placed where has the resources it needs. The second component scans the cluster and will ‘re-balance’ as necessary by moving workloads so that all VMs have the resources needed.
- High Availability (HA) – If a host dies, all of the VMs on that host will be restarted on other hosts. You can even control priority if necessary.
- Fault Tolerance (FT) – this allows you to have a VM running in sync with another VM on a different host. If the first one dies the second one continues working.
- VMware Update Manager (VUM) – The ability to upgrade your vSphere hosts without an outage for your virtual machines. It will even update firmware for some host types.
- Shared Memory – If you have a handful of VMs that have the same operating systems, only one copy of the instructions will be in memory and the memory savings will be huge. The VMs without their instructions in memory will have pointers to use the first VM’s memory.
- Flexible Virtual machine architecture – you can have virtual machines with a wide range of operating system and versions as well as RAM, networking, and CPU.
- Predictive Distributed Resource Scheduler – this is very similar to DRS, but it requires vRealize Operations and it helps DRS become predictive so it moves VMS before they have issues.
- vMotion – this is the ability to move a VM from one host to another without an outage (for that VM). It is used by DRS, but also VMware Update Manager to support putting hosts in maintenance mode so they can be patched and restarted.
- Storage vMotion – this is the ability to move a VM from one datastore to another without an outage for that VM.
As well, once you use vSphere, there is other things that you can buy that provide value such as:
- vRealize Automation (vRA) – this is a very powerful and flexible automation tool. It would support a portal system very nicely.
- Horizon View – this delivers virtual desktops and apps to end users. It has a range of desktop clients as well such as iPad which works quite well.
- Runecast – this product automatically checks your infrastructure against KB articles, best practices, HCL and security standards and alerts you to things you need to know. Works really well.
- Veeam Availability Orchestrator (VAO) – this is a DR orchestration tool that is one of the best. And it can save your business when your data center dies.
So I think that vSphere provides pretty darn good value, and they are working on the next major release and I wonder what value it will bring – I am looking forward to it.
I really do not understand why people consider paying for vSphere as a tax. But I hope that this quick article helps some people to understand the value.
