What is a private cloud? When is a private cloud suitable for you and how can you deploy it?
What is a private cloud?
A private cloud is an environment that provides computing power and storage without shared resources. The condition is that these resources must not be dependent on a single data centre, according to the definition of a cloud. Any other form may not bear the name private cloud. That does not alter the fact that there are plenty of suppliers who do, but you will read about that later on this page.
The benefits of a private cloud
- No noisy neighbor
The biggest advantage of a dedicated environment is that you decide how it is loaded. Another customer of your supplier cannot influence the speed of your applications.
- Excellent efficiency
A private cloud is scalable and at Tuxis the price is structured so that you get the benefit of your own equipment.
- Fixed costs per month
A private cloud grows in stages. Basically, when you need more capacity, a dedicated server, also called a node, is added.
- Insight into workload
It is your environment that makes it easier for you to understand the underlying infrastructure. Slow? Logging in and ruling out the possibility that it is caused by the infrastructure is very simple.
- Freedom of use
You get a virtual data centre. In it, you decide what you create, how you use resources and for what purpose. Even the most complicated infrastructures can be set up..
- Insight on infrastructure
SSD, spinning disk, number of cores, memory speed, network. It’s all transparent to your engineers and consultants.
The disadvantages of a private cloud
- Entry threshold
To start with a private cloud, a certain capacity requirement is needed to make it profitable. That threshold is lower than before thanks to hyperconverged solutions. Consider a private cloud when you need the following amount:
- 16 physical cores > ~64vcores
- 128 Gbyte memory
- 3 TB storage
- Click and run
A private cloud runs on the infra layer. That means that if you need a database, you have to run something that runs that database. It is therefore not a click, order, use environment. A private cloud is particularly useful when you structurally need certain types of capacity. On the Tuxis private clouds, you get access to the Tuxis Marketplace with many ready-made solutions which makes this disadvantage a lot smaller. And of course, you can have the setup done which gives you the convenience of the public cloud.
It is often written: “data centre failure is handled by our redundant solution”. The question is how? We think it should be three data centres to avoid split brain and not to own double capacity unnecessarily.
Realtime in three datacenters
Through the smart use of softwaredefined storage and virtualisation, capacity can easily be distributed across three data centres. When a data centre goes down, only 1/3 of it is down, which can automatically be absorbed by the capacity in the other two data centres, and that does not apply to the storage at all. In addition, the data is stored three times anyway.
The concept of private cloud
A private cloud is of course a nice solution. Privacy is important, private is nice, no noisy neighbours either. It makes use of dedicated hardware. This can be done in IaaS form or by purchasing and managing it yourself.
The term “virtual private cloud” is also appearing more and more frequently. The idea is a pool of resources. Technically speaking, you might as well rent a VPS. If the infrastructure is shared, it becomes just as less private as a separate VPS. Virtual data centre would be a better name for these services.
The fact that there are SaaS providers who also call an account in a shared environment private cloud does not make it any better.
