Cloud

What is Public Cloud?
Public cloud environments are one of the most common variants of cloud computing deployments. The cloud servers and storage resources are owned and operated by a third-party cloud service provider such as Coreix and delivered via the Internet. In public cloud, all hardware, software, and other supporting infrastructure are owned and managed by the cloud provider. Coreix Cloud, Microsoft Azure and AWS are examples of public cloud.
Within a public cloud you utilise the same hardware, storage, and network devices as other organisations and businesses - We call these tenants. In these solutions, you have access to services and manage your footprint using a web browser.
Public cloud deployments can be utilised for a wide array of solutions such as providing e-mail services, online applications, storage applications in addition to testing and development environments.
Public cloud infrastructure is on a fully distributed and resilient platform where we can provision from a single virtual machine to dedicated resource pools or even dedicated hypervisors or dedicated storage which resembles more private cloud.
-
What is Private Cloud?
A private cloud is a computing service offered either over the Internet or a private internal network to selected users (your company) only, not the general public. Being a cloud service, private clouds have all the cloud benefits of self-service, scalability and elasticity with additional control and customisation. Private clouds deliver a much higher level of security and privacy.
The main advantage of a private cloud solution is that resources aren’t shared with any external entities. A private cloud consists of cloud computing resources used exclusively by your organisation. This is hosted by Coreix on one of our data centres or multiple depending on your requirements. The services and infrastructure are always maintained on a private network and the hardware and software are dedicated solely to your organisation. These solutions offer greater visibility into infrastructure and enable more stringent cloud security in addition to easier control over data locality, improved data governance and low-latency performance.
-
What is Hybrid Cloud?
A hybrid cloud is suitable for businesses with highly dynamic workloads, as well as businesses that deal in big data processing. Businesses can split workloads between the clouds for efficiency, dedicating host-sensitive workloads to the private cloud, and more demanding, less specific distributed computing tasks to the public cloud.
Utilising the different combinations of Coreix public cloud and Coreix private cloud to match your businesses requirements. From here you can shift workloads to different cloud solutions based upon importance, demand and security. The public cloud will allow for any variations in demand as we can instantly scale up or down your requirements to cover any spikes in resource intensity.
You can also dedicate any sensitive or critical information to your private infrastructure with the rest of your applications running on your public cloud offering. This also allows you to connect infrastructure that might not be suitable for public cloud and utilise the public cloud benefits in the areas that are suitable for it.
-
What is Multi-Cloud?
Multi-cloud is the concept of utilising multiple public cloud solutions such as Coreix Public Cloud and Microsoft Azure together for resiliency or to take advantage of specific features that they provide.
Organisations are increasingly utilising multiple private and public clouds to deploy applications in an attempt to avoid vendor lock-in and exploit the best features of each platform. In its purest form a multi-cloud solution embraces multiple public cloud platforms to leverage the best of all worlds.
Dedicated Servers
-
I need an old version of an Operating System, is this possible?
It is possible, while we don't like installing legacy or EOL Operating Systerms and strongly advise against it, providing we have the right security imposed on the system and network we can help you achieve your goal.
-
Why are the processor details so vague?
Processors and models change frequently. We highlight the core counts and types of processors we are supplying so you can get a rough picture of the type of server you will receive.
Hardware is the current generation and as such, you shouldn't be disappointed with the processors provided.
If you have specific requirements then you do have the ability to work with our consultants and build a bespoke system.
-
I want older hardware, is this an option?
We do maintain a stock of older hardware, you can always contact sales directly and they can give you the current stock of older hardware which we can offer at a reasonable price.
Nevertheless, power prices are on the increase and as such much of the savings that you may achieve from older hardware could be outweighed by the legacy power utilisation of older hardware.
-
I want RAID x, but it isn't an option, can I use this RAID level?
There are custom storage solutions available on the bespoke series and all RAID levels are available from Coreix, we just don't necessarily recommend them, nevertheless if you have a use case we are more than happy to accommodate.
-
What is hot-swap?
In the case of hard drive corruption, failure or addition, the 'hot swap' hard drives are added or removed without having to take the machine offline. This heavily reduces the effect this has on the uptime of the equipment.
Cold swap hard drives require the equipment to be turned off before the drive can be inserted.
In situations where RAID is present, it is often preferable for business continuity to have hot-swapped drive bays since faulty drives can be replaced with zero downtime.

Colocation
-
Can I provide my own IP addresses on your network?
Of course, the networking department at Coreix will be more than happy to assist you with advertising from our AS.
-
Can I provide my own power bars?
Yes, providing they are PAT tested prior to being commissioned. The technical support team on site will help you with that on the day of installation.
-
Can I use my own transit?
Of course, we can even help you arrange transit from our connectivity partners such as Colt, Century Link (Level 3) or Cogent.
-
What ampage do I need for my solution?
The ampage required to run your server solution is dependent on the size and processing intensity of your equipment. For example, a colocation quarter rack is likely to need 2-4 amps of power, whereas a full colocation cabinet will need between 8 and 32 amps of power. If the servers in your rack are high powered, with large hard drives and top of the range CPUs, you will need a higher ampage for your colocation rack than if you have low-end servers in your rack. To ensure optimal performance, you should ensure you stay well within your power usage limits.
-
Do I need a full, half, quarter or multi-rack solution?
Whether you need a full, half or quarter rack colocation solution ultimately depends on your company's own individual needs and requirements.
Full Rack Colocation (42U/44U/48U)
Businesses needing full rack colocation are likely to require hosting for a number of servers with dedicated connections and high bandwidth requirements & are looking for full access to their own individual rack. This includes large e-commerce businesses that rely on a large amount of database processing power and large multinational companies that host their sites across the global market.
Half Rack Colocation (22U)
Half rack colocation is often used as a disaster recovery solution for larger companies as the majority of companies take the jump straight from a quarter rack straight to a full rack. This half rack will be located in an alternative data centre facility to the full rack solution, so if the worst should happen, all data can be backed up and available offsite. Small to mid sized businesses also occasionally employ half rack colocation solutions, although full rack colocation offers a better opportunity to expand than half rack solutions.
Quarter Rack Colocation (11U)
Perfect as an entry level colocation solution; combining significantly lower costs than a full rack colocation with upgradable bandwidth and power where necessary to ensure a flexible solution. Quarter racks are often lockable, ensuring extra security for your equipment. Quarter racks do have their limitations and are unlikely to be suitable for larger businesses that require an increased level of processing power or bandwidth - if you are consistently breaching your limits, quarter rack colocation becomes no longer effective for your requirements. Quarter rack colocation is ideal for smaller businesses that are looking to host their equipment in a secure facility that adheres to strict SLAs for uptime and other key variables. -
How much bandwidth is necessary for my needs?
This purely depends on what your equipment is being used for. Examples of server usage that may require large amounts of bandwidth are database driven servers (such as ecommerce sites), web servers and upload sites. Any server that is being utilised for a site with heavy traffic is likely to need large amounts of bandwidth. You are unlikely to need large amounts of bandwidth if you are running a basic website from your server or you are using your server as a backup device, as backups can be scheduled so as not to exceed limited bandwidth limits.
Connectivity
-
What is a Layer 1 service?
The physical layer is responsible for the transmission and reception of raw data between devices via the transmission media. It converts data from bits into electrical, radio or optical signals.
The services are purely a physical connection and have no interfering hardware in between that manipulate the data, thus making these services the most secure.
-
What is a Layer 2 service?
The data link layer provides point-to-point data transfer which is a link between two directly connected nodes. It detects and possibly corrects errors that may occur in the physical layer.
These services are utilised to connect networks together i.e. connect two office sites together and keep them on the same LAN.
-
What is a Layer 3 service?
A layer 3 service is basically a fully routed service such as Internet connectivity. We provide IP addressing (IPv4 and/or IPv6) and you have full global Internet routing available via this circuit.
-
What networking equipment do I need to receive IP transit?
If you just require default route transit then any simple layer2 device will suffice since Coreix can do all the routing for you and we can present you an interface with a gateway and an IP allocation. You can plug this in and receive Internet transit.
If you have your own AS number then naturally you will need a BGP enabled router of some form. If you have your own AS number then you probably won't be reading this!
-
Can I use my own AS and IP's with Coreix?
Of course, you can use your own AS number and IP space, our engineers will be more than happy to assist.
