Who Should Use Bare Metal and Who Cloud Platform? Definitely there should be should be some logical criterion to choose the right platform. Our reference Bare Metal is Rackspace OnMetal® and Cloud Platform is by any giants – preferably running OpenStack Cloud Computing Software. 128 GB Bare Metal can cost the same like a Cloud Server instance. Basic difference is in usage. Like Dedicated Servers are for specific usage, may be for example – GitHub uses Rackspace Dedicated.
Who Should Use Bare Metal and Who Cloud Platform : Basic Technical Part
Dedicated, Private Cloud, Hybrid Cloud and Bare Metal – too much options? The difference is fully on virtualization. Zero virtualization for Dedicated. A good Dedicated means equivalent to own data center’s device. Indeed, for Hybrid on Rackspace we often refer to consult with this way. There are Blue Pill, Red Pill tests to detect fraud in the name of Dedicated. Usually the B Grade hosting uses various cheating ways to offer dedicated at $100 / pm. The level of cheating can be at networking level – it is near impossible to detect by the most. Colocation is nothing but your own machine – your machine’s tenant relationship becoming off. We normally are tenants, we have no legal rights on the physical machine. Colocation has some of reasons to use. Rackspace or the bigger brands actually sells their own custom ordered hardware for colocation.
From the point of switch, hub, networking to the physical processor – all are fully for one reason of usage. One should read the article – What is Bare Metal Hosting, to understand the basic methodology we use for Bare Metal.
Bare metal uses the similar software like used for Public Cloud. In a bare metal virtualization hypervisor does not require administrator to install a server operating system. Mostly they are configured with cloud automation. In Bare metal virtualization the hypervisor has the direct access to hardware resources, which results in better performance, scalability and stability unlike typical Public Cloud. Public Cloud is a compromise for a better performance with a limited budget. The automation formula is usually optimized by both experts on the field.
Who Should Use Bare Metal and Who Cloud Platform
We are not interlinking towards the older articles, if you need, perform a search with the terminologies. Cloud Platform can be Public, Hybrid or Private. Public can be IaaS, PaaS and SaaS. We are considering SaaS only. IaaS / Cloud servers are instances – it is a multi tenant environment where security is not very important – a medium sized blog. What internal data security it will require in comparison to a bank’s website? We want Google crawls, a Bank’s server can not invite to crawl all parts of the server.
Dedicated has a basic risk – if there is sudden unexpected load, the processor(s) can catch fire. Hard disk failure is rare now, almost all components are hot swappable but the owner have to bear the cost of hardware for collocated servers. Dedicated’s risk is minimized by the fact – the customer will not be charged. Dedicated might require several experts to properly configure.
Advantage of Bare Metal is combination of both the worlds except unlike Hybrid Cloud, horizontal scaling is easier. Usually the Bare Metals are I/O optimized for specific task. The application servers will more data intense work. Bare Metal with 512 GB RAM is usually for application server. Networking is usually separate from the public cloud. KVM is a Bare Metal Hypervisor. A Bare Metal hypervisor is also traditionally said as Type 1 hypervisor – it runs directly on the hardware and that hosts guest operating system. Virtualized, yet faster than native Cloud. Now, the pool is fully how the service provider has created – Rackspace OnMetal servers are single tenant with no hypervisor. Multi tenant has one client.
When we say “16GB Server Instance” on our tutorials, it means we are “booking” a part of a multi tenant system. We usually mount SSD for faster performance.
For a consistent computing need, but within a budget; Bare Metals are the best. Now, you’ll require a Cloud Architect or Cloud Consultant, usually Dell, HP, Fujitsu, Rackspace, IBM – all Provides free consultancy for the decision and move. You should not ask here and there but directly take consultancy of the provider for selection.
