Public, Private, and Hybrid Cloud, What's The Difference

Cloud Solutions have taken over the infrastructure of countless organisations over the last 15+ years and has become a must-have service for any serious business to run their operations effectively. The entrust IT Group have been at the forefront of cloud implementation for over 10 years. We saw early on the potential of the cloud, offering everything from increased security and process streamlining to reduced costs and the ability to access files and services from anywhere using an internet connection. Since then the cloud has solidified itself as the future of computing.

Despite the cloud being utilized in more businesses than ever, many are still unfamiliar with this technology and are only now starting to bring their businesses' IT into the future. Without the right guidance, the cloud can seem like a daunting place, so we’re going to break down the different types of cloud and their benefits.

In this blog, we’ll help you distinguish the differences between Public, Private, and Hybrid Clouds and offer our Cloud Solutions White Paper to help you decide which cloud would suit you:

What is a Public Cloud?

Public Clouds are the most common and well-known cloud computing model. All the resources needed to run the infrastructure, everything from servers, storage, networking components, and software support are all owned and managed by the third-party provider. These services are then accessed by your users over the internet via a web browser. Some of the public clouds you may have already heard of include Microsoft 365, Google Cloud Platform, and Amazon Web Services.

Even though you share the infrastructure with other organisations, your data and workloads are separated from theirs in a safe and secure virtual space.

Benefits of using a Public Cloud Service

  • Scalability – You would have the ability to quickly scale your resources up or down infinitely as the resources you would need are readily available
  • Cost Saving - Instead of having to make large upfront investments into hardware, installation, and software, you simply pay for a service subscription. Public cloud services are usually paid on a per-usage deal, meaning you only pay for what you need.
  • Reliability – Cloud providers maintain large, geographically distributed networks of servers, together with sophisticated redundancy and failover strategies, to ensure customers against outages and downtime.

What is a Private Cloud

The Private Cloud unlike Public Cloud is a specialised cloud infrastructure built specifically for your business, it provides the same scalability and flexibility as the Public Cloud, with the added benefit of increased control of the security and system itself. This makes customization and regulatory compliance easier to manage, which is why the private cloud is perfect for businesses which require strong regulation or larger businesses. You will have far more control over the solution, and it can better fit your requirements.

Benefits of using a Private Cloud Service

  • Maximum Security – An environment dedicated to a single customer affords maximum levels of protection against unauthorized data access and theft.
  • Control – By having direct contact with the hosting partner, the control you have over the environment is greater
  • Flexibility – Due to the environment being for your businesses alone, you can transform it to respond to evolving technology markets and opportunities
  • Regulatory compliance – Private cloud infrastructure can be tailored to conform to any strict privacy or government rules in relation to sensitive and confidential data/workloads

What is a Hybrid Cloud

Hybrid clouds combine public and private cloud resources to yield the advantages of both. High levels of integration and orchestration are must-haves to enable seamless movement of data and applications between the two types as needs change.

Hybrid solutions give you the flexibility to choose the optimal cloud for each application and gain the ability to move workloads freely among clouds depending on the circumstances of your business. A hybrid cloud strategy enables the organization to meet its technical and business objectives most cost-efficiently and effectively than it could with either public or private cloud alone.

Benefits of using a hybrid cloud

  • High Flexibility – You can respond immediately and effectively to unpredictable demand surges with public cloud infrastructure, and scale back down when the spike subsides, with no impact on other workloads running in your private cloud
  • Resource optimization – Flexibly deploy applications to maximize utilization of both on-premises resources and cost-saving public cloud infrastructure
  • High reliability – Applications and data can be distributed across multiple data centres for highly effective redundancy, failover, and disaster recovery

Which Cloud is Right For You, Find Out Using Our Expertise

Within this blog, we’ve taken a deep look at the three different types of cloud, and what some of their benefits are. Whilst some offered better security and customisation, others gave increased scalability and reliability. There is no “right” cloud, so how do you find out which one you should choose.

To get the most effective use of cloud platforms completely depends on the understanding of your company, its goals, and requirements. If you want to find out which cloud solution would be right for you click the linked image below to download our ‘cloud services’ White paper⬇️
