Now that 2018 is here it is an ideal time to clean up your estate. The problem is that rightsizing and cleaning up the estate isn’t always a straightforward proposition, especially when done by hand.
Correctly rightsizing a VM is a black art. You can look at a point in time or a week but that server may not peak until one or two specific points in a single month. It takes skill and time. The other big issue is that doing such profiling in a large estate by hand doesn’t stack up financially.
Out of the box most hypervisor platforms don’t really have rightsizing functionality / reporting built in. The story doesn’t stop there. Buying in a solution takes time and obviously costs money to run.
Recently I have written a lot about Embotics. As well as being a pretty good CMP (Cloud Management Platform) it installs really quickly. I setup a POC inside thirty minutes.
So what? It means that within a very short time the administrator can see what is oversized or conversely undersized and give suggestions on rightsizing. Obviously, the longer it is left to collect statistics the more accurate it will be. I’d suggest a month at least to get a good grounding.
Sure there are other solutions but I like an easy life. It is simple to install, use and will even do the resize for you if you so desire! Other systems can do this but they aren’t as quick to install and certainly aren’t as easy to use.
Check out the video I did and see just how easy it is, honest. Doing a rightsizing exercise is the way to go with any decent sized estate. It had been known for Embotics to be run in a brownfield site and recover enough resource to actually pay for the Embotics licences and support for the year.
So I was having lunch with a ex work colleague last week who now works for one of the major cloud providers and we started chatting about companies who just don’t get a very major cloud related point….
Cloud is not about servers, but services.
It may seem a somewhat obvious statement but there is still a huge element of “I want to own everything I use.” The way to look at cloud beyond a quick VM here or there is that most cloud providers already provide the services for your application requirements already…. Database, check. Web services, check. Service x, check. Have you ever seen how many services Amazon has? A lot.
The point is recreating everything from on-premises in IAAS, standing up your own virtual servers is overkill, kills the value proposition and misses the point.
Sure there are some specific cases (Security, compliance, contractual obligations and such) where an administrator will need to keep everything on “infrastructure” they control and manage. If that’s not the case, your doing it wrong and in a very expensive, long winded, re-inventing the wheel fashion.
Why stand up a full SQL server when you can get a DB service for a fraction of the cost and without any of the management overhead but the same (or better performance).
So I was fortunate enough to be given the opportunity to attend the NSX test drive experience. It was very worthwhile. So what’s it all about?
Firstly, Dell/EMC/VMware looked after us very well. I certainly wasn’t expecting bacon and egg sarnies in the morning ;). Anyhow… the course.
The class size was 16 (The maximum) and was delivered at EMC Manchester. Essentially it was quality as well as quantity 🙂
So it was described by several of the trainers as the ICM (Install, Configure & Manage) without the fluff. To be sure, it truly is a techie course for techies. No marketing slides to be seen (Mr VMware, please don’t take that as a hint 😉 )
The whole point of the course is to help people understand NSX and the advantages it brings and how NSX works under the covers. There are too many advantages to list in this short shout out but the way the course was delivered it absolutely made sense.
Day one was how VXLAN works, how to install and configure NSX and the theory. It was almost identical to those courses that you beg management to send you on.
Day two delved even deeper into the whole security setup and how the whole security functionality in NSX works. It may seem simple on the surface but there is a huge hidden layer of complexity if you want to dive that deep.
Other items included touching on Orchestration and how to setup NSX in a multi-vcenter environment.
These courses are free. If you have a good account manager just ask. I went from knowing a little about NSX to understanding the vast majority of how a basic NSX setup works.
I found it provided an excellent opportunity to the question of “Where do I even start” with NSX.
For anyone that is interested in a course 101 tour of setting up NSX I will be be writing an article that will be appearing on SearchVMware soon.
It would be remiss of me to not just say a big thanks to Mike, Phil and Kaela for making it happen. You guys rock!
