When researching cloud computing, you’ve probably come across the terms ‘public’, ‘private’ and ‘hybrid’ cloud.
The first thing you need to know is that each environment allows your business to access computing resources, from customer relationship management (CRM) software to digital storage. However, the manner in which your employees use applications, manage databases, run websites and so forth depends on your company’s cloud delivery solution.
Each business is different, and requires a distinct set of tools to support its operations. Hybrid, Public and Private Clouds deliver such tools in their own, unique ways. Choosing one or the other depends on your business needs. For example, a small business that is 100 per cent office based may benefit from using a hybrid approach consisting of customer-premises equipment and cloud-based communications, whereas a more mobile company would benefit by utilising more cloud-based services that are less reliant on the company’s physical location.
Basically, the goal is to provide the business easy, fast, cost-effective access to the information and communication technology that they need to excel at performing their tasks.
Before detailing the differences between a private, public and hybrid cloud, you need to understand the technology behind these delivery models.
Efficiency, scalability and convenience
From a technological standpoint, cloud computing is a solution that enables consumers and professionals to easily access storage, servers, software and other resources through an internet connection.
Cloud service providers design these ecosystems with two core technologies: virtualisation and automation.
While automation allows the cloud to allocate resources and manage workloads without human intervention, virtualisation logically (i.e. digitally) divides hardware into multiple, virtual iterations. So, when you apply virtualisation to a computer, you enable the machine to run multiple versions of itself simultaneously. It’s essentially the best way to get the most out of your equipment.
The Private Cloud
A Private Cloud is a computing environment owned and operated by an IT services provider. The services provider leases the computing resources within its Private Cloud to its customers. This means companies don’t have to share web-based services with other organisations.
One of the key advantages to using a Private Cloud is that businesses have greater control over their resources. However, supporting this infrastructure can prove time-consuming and difficult. That’s why many companies outsource administrative duties to managed service providers capable of dedicating their expertise and resources to optimising their Private Clouds.
A Private Cloud allows you to deliver all your business ICT services from just one provider, so you can have your email, files, print services, collaboration messaging, and telephony all delivered from your Private Cloud.
The Public Cloud
The Public Cloud is an online service that is accessible not only to businesses, but also to consumers. Dropbox, Amazon Web Services (AWS), Gmail and OneDrive are examples of public cloud services.
Public Clouds are more of an a la carte offering in comparison to a Private Cloud. You can choose to host your website with AWS, email with Gmail and do some basic file sharing with OneDrive. This approach suits the micro business, but is not a manageable solution for a business with a team of people who need to collaborate to meet goals.
Part of the challenge with Public Clouds is their manageability. Many Public Cloud services are trying to address this to make them more appealing to the Enterprise, but when you are subscribing to numerous services from numerous Public Clouds, there is always going to be a challenge with managing access.
Public Cloud services can also bring additional security risks to your business, mainly due to the fact that anyone can sign up to a Public Cloud service and then start storing company information in a location that is not controllable by the organisation.
The hybrid cloud
As you may have guessed, a hybrid cloud is an ecosystem that consists of resources from a Public Cloud, Private Cloud and, when needed, equipment within a client’s offices. TechTarget noted that an enterprise may use multiple Private Clouds or Public Clouds to create a hybrid infrastructure, allowing it to use services from different vendors.
In areas where high speed internet connectivity is either costly or not available, a hybrid approach with equipment based on client premises is quite common, which alleviates the demand on the internet connection. Cloud Communication services such as cloud based email isn’t a huge drain on an internet connection, so this is often a good element to migrate to the Cloud first – this gives the business uninterrupted access to critical email services on all their devices.
The advantages associated with hybrid clouds include:
- Running mission-critical and sensitive workloads on the Private Cloud or CPE
- Allocating software testing and development tasks to the Public Cloud or Private Cloud
- Automatically provisioning unexpectedly high workloads to the Public Cloud or Private Cloud
Typically, Public Cloud providers and IT service providers will help businesses establish the network connections and architectures necessary to maintaining a hybrid cloud. Yet, this isn’t always an option.
How a Managed Service Provider can help you choose
Choosing a public, private or hybrid solution ultimately impacts your ability to maintain and adjust operations. A managed service provider will assess your business’s day-to-day processes to select the most appropriate delivery model. The chief goal is to deliver a cloud system that serves as the backbone of your organisation, enabling you to run a competitive, adaptable business.
The technology world is becoming more stable and easier to access, but it also presents a wide array of options that can be difficult to comprehend. The team at Scope Logic can translate technical jargon into the business language you understand. We’ll help you select the technology that will best support your operations, ensuring your business can expand and adjust to an ever-changing market.
