A beginner’s guide to Cloud Computing
What is Cloud Computing?
The rise of remote working has led to significant, widespread use of cloud computing. You have most likely experienced the cloud in the workplace already. For example, if you can access company files remotely by logging into Google drive.
Why is it called The Cloud?
“The Cloud” is a common metaphor for the internet. Cloud computing services gained their namesake due to their secure virtual locations. As the precise location is unimportant to consumers, virtual storage was once referred to as “belonging in a cloud somewhere”. It has now become a widely accepted term.
Cloud computing refers to the instant delivery of computing resources via the internet. It avoids the need for businesses to purchase and maintain physical servers to store data.
Users can access the same files and applications from almost any device. For example, if your laptop breaks, you can log in elsewhere and access all your accounts, photos, videos and conversation history.
Cloud-based services offer flexible payment options, with the choice to expand your storage space if you need to.
How does cloud computing work?
Cloud computing utilises a technology known as virtualisation. This allows IT services traditionally bound to hardware to be provided virtually. The cloud is made possible using a collection of simulated virtual machines that operate the same way as a physical computer.
A company’s data and information is stored on these virtual servers and looked after by a cloud infrastructure provider such as Amazon Web Services (AWS) or Microsoft Azure. Users can access this information on any device with a secure internet connection.
Arc Systems are a Microsoft Gold cloud solution partner. We can host your systems in our private cloud, offer a hybrid cloud solution with Office 365 or deploy within the Microsoft Azure public cloud.
Who uses cloud computing?
Even if you haven’t invested in the cloud yourself, you can be almost certain that you have interacted with a platform that has. Businesses spanning multiple industries have migrated to the cloud environment.
Companies like Pinterest, Instagram, eBay and PayPal use the cloud to store and manage data created daily by their users. Cloud computing provides great elasticity, meaning companies can rely on it to expand as their customer network and demand increases over time. This means these businesses can handle heavy site traffic with zero downtime.

Disaster Recovery – By investing in a cloud computing system, your business will be able to recover critical data and systems after a breach. Cloud disaster recovery works by backing up the entire server to an offsite data centre. You can access securely in the event of a disaster.
Types of cloud computing
Private Cloud Services
If your business wishes to use a cloud resource exclusively, the private cloud (also known as an internal or corporate cloud) is the best solution. Private cloud services create a private internal network for approved users within the business is highly secure and uses firewalls to help keep sensitive data confidential and protected.
At Arc Systems, we can host your company’s systems in our secure private cloud. We will maintain the infrastructure on your behalf and keep everything running smoothly.
Advantages of a Private Cloud
Greater control – Businesses have more control over how their resources are managed and accessed as they choose precisely who will be given log in details.
Increased security – The private cloud’s private cloud’s best security feature is obscurity. It is improbable that people outside the business network will know it exists.
High performance – As your company will have exclusive independent access to all cloud services, overall speed and performance will increase.
Disadvantages of a Private Cloud
Higher cost – Maintenance fees are often higher than a public cloud, requiring skilled technicians to manage the on-site servers.
Limited scalability – As the private cloud is hosted internally, it can only be scaled according to the resources available to the business.
Public Cloud Services
Public clouds provide a shared platform used by multiple businesses across the globe via the internet. They are often a cheaper solution as your company will share the cloud with others. However, this does not affect speed or performance.
All of your employees can use the same application and services simultaneously, provided they have an internet connection. They operate on a pay-per-use basis. Public clouds are owned, maintained, and run by businesses, government agencies, or both.
Advantages of a Public Cloud
Lower Cost – As your resources will be shared with a more significant number of consumers.
Not tied to a specific location – Public clouds are location independent with no on-site servers required.
Quick, simple setup – Businesses and individuals may purchase public cloud services online that can be deployed immediately.
Unlimited scalability – A public cloud can expand with your business. You can increase the size of your storage space at an affordable monthly rate.
Disadvantages of a Public Cloud
Less secure – As resources are split between multiple businesses, there is a higher chance of a data breach.
Less customisable – As public clouds are designed for multiple users, you cannot create many bespoke changes.
Hybrid Cloud Services
This solution usually combines the public and private cloud environments. This involves the connection of at least one public cloud and one private cloud to manage computing workloads. It allows businesses to reap the benefits of multiple cloud computing vendors to create a cost-effective solution.
Advantages of a Hybrid Cloud
Agility – Enjoy the benefits of the public cloud, with the customisation ability of the private cloud.
Deployment – The hybrid cloud connects both public and private cloud services; this makes data transfers faster. It is optimised for the specific needs of your business.
Flexibility – Avoid choosing between public or private and gain the benefits of both. For example, you could store personal, sensitive data in the private cloud and standard information on the public cloud.
Reliability – If a public server fails, the business can rely on its internal private cloud infrastructure until the problem is resolved.
Disadvantages of a Hybrid Cloud
Lack of control – To implement changes, this must be done by a technician via the private cloud and adapted for the public cloud. The end-user has no control over this.
Cloud compatibility – Occasionally, the public infrastructure can be unreliable due to reduced internet connection; this can affect the performance of the hybrid cloud environment.
Infrastructure as a Service (IaaS)
This is the most basic cloud service. This is when a business rents its required storage from a cloud provider. They can then start building new applications using this online space and can update it at any time, anywhere. We provide the space; you bring the tools.
Benefits of IaaS

Software as a Service (SaaS)
This service involves connecting users to cloud-based apps via the internet, like Microsoft Office 365. Your business will rent an app for customer/employee use. Users just need to log in on a web browser to use your application, for example, Slack or MailChimp. Both hardware and software will be managed by your service provider.
Benefits of SaaS
Mobilise your workforce – Your team will be able to use the app in any location as long as they have internet access. Your cloud provider will ensure your app is optimised for every type of device from desktops to tablets and mobile.
Analyse app data, anytime, anywhere – All data relating to your application will be stored in the cloud. Information can be accessed, edited and restored if a device breaks.
