In the past, if a particular host in a traditional on-premises infrastructure reached 30-40 percent utilization, this would be cause for alarm in the data center. The IT staff would frantically call meetings and questions would start flying:
- What will happen if demand goes up?
- How quickly can we get a larger server?
- Is there space and power in the data center?
- What about the budget? We aren’t due for a refresh for three years!
- How will we move the application(s) to the new server?
- Will the usage level back down; and, if so, what do we do with the new bigger server?
Basically, panic would set in.
But in today’s world of cloud computing, it will be OK! In fact, if an application is using LESS than 70%, I always say you’re giving away money to the cloud service provider. So there is no cause for alarm at all. Because with cloud, your outlook on the world looks different and you can approach your utilization with a calming Zen attitude.
It’s Time to Let Go of the Past
Let’s look back at the on-premises infrastructure scenario. Unless your application can scale horizontally, you are left with no choice but to add more CPU, RAM and possibly storage. This often would mean – at minimum – a larger VM, or worse, a larger host. If it is the later, this is when real panic starts to set in. Of more concern than “is this in the budget” is the prospect of what happens if we purchase a larger host. But again, in a relatively short period of time, what if that proves to be inadequate? I know that the Arrow community understands this dilemma. So what I want to suggest is that you cannot bring these same fears and thought processes from the past to today’s architecting in the cloud.
So take a deep breath and stop planning and trying to guess what will happen in the next three to five years. Instead, build out your cloud infrastructure properly and then re-evaluate it regularly. As an example, the perspective of many “20 somethings” today is that they would rather not own a car. Instead, they enjoy the flexibility of “cars as a service” like Lyft and Uber. If they are going to work, Lyft Line (sharing your ride with a stranger in an economy car) works well. If it’s a big night, maybe Lyft Premier (think BWM 5 series or better) is in order. And of course, who can forget that time you had seven people needing a ride home after that amazing concert? Uber XL was perfect for that.
In that same vein, architecting for the cloud requires a new perspective, too. While you wouldn’t want to make changes every day on your infrastructure, maybe a quarterly review with possible changes are in order. This is something that you would add into a managed service. In addition, hyper-scale public cloud providers offer the needed tools and reporting to complete this for your customers’ workloads and offer a great service differentiator for partners that choose to provide this level of service.
Cloud Lets You Get More Bang for Your Buck
When you consider that cloud is built on a pay-for-consumption model, it is clear that good management is a major key to success. Consider this: If you “sleep” your virtual machines for just eight hours per day, that alone represents approximately 25 percent reduction in cost. How about weekends? What about those machines that aren’t even used on a daily basis? What about that massive server that is purpose-built for major computations that occur on an infrequent basis? The savings possibilities are endless!
So with cloud, you’ll get more bang for your buck and a myriad of value propositions, such as:
- Server-less computing
- Scale sets
- Clustered services
- Just-in-time provisioning
- Increased security
- Economies of scale
- More effective support model
- And the list goes on and on
