=[https://rackspace.com Rackspace]=
Rackspace as the founder of the openstack initiative has a great relationship to opensource communities, which is providing customers with more choices and ease to switch providers.
The usual virtual machines and block storage (ssd or disk) are provided. Furthermore a wide range of other services (mysql, loadbalancers, object storage, etc.) are offered. The object storage with the ability to use Akamai as [https://en.wikipedia.org/wiki/Content_delivery_network CDN] and additional features (expiring objects, static site hosting, etc.) is something to consider for public objects. Hosting with Rackspace provides you with a lot of choices, backed by opensource projects. Switching providers is made easier compared to others.
The hosting location and Rackspace being an US company raises privacy concerns.<br/>
Rackspace is providing dedicated servers and the ability to connect them to virtual machines to provide a hybrid hosting solution, but one of the key components for the "private infrastructure" is data privacy and therefore Rackspace is not usable for the planned infrastructure.<br/>
(Virtual machines, block storage and object storage are considered for cloud-bursting of public data)

=[https://aws.amazon.com Amazon Webservices]=
AWS is the biggest cloud provider in the market. Key products include virtual machines (EC2), block storage (EBS) and object storage (S3). AWS gives you a great amount of additional services (mysql, nosql, loadbalancer, etc.).
Using these gives the possibility to develop less and strengthen your key ideas(code).<br/>
The downside of using AWS, especially the additional services, is lock-in. It is not easy to switch providers if you need to.
Another downside is the server location and US company status.<br/>
Building projects/services on-top of AWS is great, but considering no dedicated servers, the lock-in problem and the privacy issues, AWS is not usable for the planned infrastructure.<br/>
(No consideration for cloud-bursting weighting the closed infrastructure)

=[https://cloud.google.com/products/compute-engine Google Compute Engine]=
Google Compute Engine is providing virtual machines on a massive scale to customers. With products such as object storage (Cloud Storage) and services for crunching massive amounts of data. Google has entered the market late, but is providing a great deal of products.
It is designed for more specialized workloads (data crunching, batch-processing etc.) and not as general purpose as AWS and Rackspace.
As with AWS, Google is using a closed system and lock-in problems can arise, furthermore no dedicated servers can be provided.<br\>
(No consideration for cloud-bursting weighting the closed infrastructure)

=[https://df.eu domainFactory]=
DomainFactory is one of a few "Cloud providers" in Germany, where you have the possibility to scale as you need. (Jiffybox.de)
With all locations within Germany data privacy is no issue with domainFactory. 
Additional products available are shared hosting and managed servers, unfortunately no dedicated servers can be purchased and therefore we can not host the private infrastructure within their ecosystem.
(Jiffybox could not be considered for cloud-bursting, because of missing api compatibility to scalr)

=[http://noris.net Noris]=
Noris is providing datacenter services to subcompanies (providing colocation). They sell shared hosting and virtual machines, therefore they were dismissed, after the decision for not using colocation was made.<br/>
(Mainlab could not be considered for cloud-bursting, because of missing api compatibility to scalr)

=[http://de.inter.net inter.net]=
Inter.net is providing dedicated servers and colocation with a few great features like high availability and load balancing. Additionally shared hosting and virtual machines can be purchased.
Inter.net is providing great products and a great infrastructure within their datacenter.
For the planned infrastructure dedicated servers from inter.net were considered, but in the end not used as a result of a higher price for less resources than possible from other providers.

=[http://mainlab.de mainlab.de]=
Mainlab is providing virtual machines and colocation through ([http://rackbase.de rackbase.de]) to their costumers.
No detailed information looked up.<br\>
(Mainlab could not be considered for cloud-bursting, because of missing api compatibility to scalr)

=[http://rh-tec.de rh-tec.de]=
With colocation and dedicated server hardware provided rh-tec started out as a reasonable possibility for hosting the private infrastructure, but the dedicated servers are not commodity hardware and therefore have a bad pricing point compared to other commodity hardware products. For the private infrastructure with failure handling build in, paying more for a non commodity server is not resulting in great availability gains and therefore is something not worth it.
As a result rh-tec.de is not usable for the private infrastructure.

=[http://interxion.com interxion.com]=
Interxion.com has a wide range of server housing locations and is considered a great place for multi datacenter colocation solutions. Data privacy depends on the chosen datacenter location. Be careful.<br\>
Interxion was dismissed from the list of considered providers, after the decision for not using colocation was made.

=[http://imt-systems.com imt-systems.com]=
From shared hosting over dedicated servers to colocation imt-systems is providing a few solutions for their customers, but with the decision not to use colocation and only non commodity server leasing available, the choices was made to not use imt-systems for the planned infrastructure.

=[http://wusys.com wusys.com]=
Wusys provides a wide range of different services to high-end users. It is providing colocation, non commodity dedicated servers and additional application and server products. Viewing all available products was out of the range of the research, but for business like applications wusys.com could be a great provider. 100% connectivity is one of a few great things offered.<br\>
For the planned infrastructure the available products were not right and we chose to not go with wusys.com.

=[http://datacenter.de datacenter.de]=
Datacenter.de was dismissed from the list of considered providers, after the decision for not using colocation was made. No detailed information was dug up, as the provider was only supplying colocation and virtual machines.<br/>
(Datacenter.de could not be considered for cloud-bursting, because of missing api compatibility to scalr)

=[https://hetzner.de Hetzner.de]=
Shared hosting and virtual machines are alright, but the shining stars are the cheap dedicated servers.
Hetzner is one of the cheapest hosters in Germany and also providers value adding services such as colocation and KVM-IP etc.. It has a good interface to administrate the servers and rescue them if needed from failures.<br\>
It is one of the best hosters to have your development box or services/projects hosted, which do not need always available considerations. The boxes provide a great value/price ratio, but when more features are needed it can really become expensive. For additional services Hetzner is letting you pay 15€ for their "Flexipack" and additional fees for IPs (IPv4 - monthly price) etc..<br\>	
The advice given here. Do not rely on 99.99% uptime and try to avoid complex setups due to huge fees.
For the planned infrastructure a private network was needed, this could be provided by Hetzner for an additional amount of money. The main problem we faced, was the public network binds IP addresses to individual servers, which makes it really hard to setup keepalived or failover solutions.<br\>
Hetzner was not chosen for the planned infrastructure mainly because of the additional fees and complex methods to achieve IP switching (not even possible yet with IPv6).

=[https://manitu.de Manitu.de]=
Manitu provides shared hosting and cheap commodity hardware servers with additional options for high-end servers. The commodity hardware servers are predefined and do not give you a lot of choice (maximum RAM 16GB...).
The provided public network is separated from other customers + has the ability to assign IPs to servers (keepalived is working). Additionally a private 1Gbit/s network can be established between servers. With a mothly price of 5.99€ per server.
IPv4 addresses can be purchased at a monthly price.<br\>
With the minimal choice for server components and additional fees for IPs and internal network Manitu was considered till the end, but dismissed as hosting provider in the end.

=[https://vollmar.net Vollmar.net]=
Virtual machines, commodity servers and high-end server hardware is available to reasonable prices. While working with vollmar.net the support was helpful and information was supplied fast.
The products we focused on were the commodity servers available. They have an easy pricing scheme and give you a lot of choice what your server should look like.
Information about additional features, which we needed, were not provided on the website. For the planned infrastructure  a private network (1Gbit/s), a public network (separated from other costumers, preferably a vlan) and additional IPs, which can be assigned to any of the servers within the environment are needed.
A private network is free for 2 servers and with 2+ servers a small fee is assigned. KVM-IP is provided free of charge for 2 Hours, installation data (.iso) can be attached to server during this time-frame).
Additional IPs (IPv4) have a one time fee only and will not cost you forever. IPv6 is free of charge.
The public network is a separate vlan and IPs can be assigned freely to the servers (making keepalived etc. possible).<br\>
The consideration to go with one server was rethought with the great choice vollmar.net provided and the decision was made to use 2 commodity servers to provide redundancy. The following hardware was chosen:
*AMD QuadCore 2,5GHz | 16GB Ram | 2x1TB SATA | 3000GB Traffic (with 10mbit/s always available)
*Cost for each server per month: 59.00€
*Setup costs per server: 49.00-99.00€
*Additional IPs one time cost: 29.99€

More resources considered. More information if the resources above are sufficient as a starting point after the initial test.
