Public Cloud Vs Private Cloud – Which Cloud is right for your business?

Now more than ever, businesses are considering cloud-based solutions for their data requirements. A huge benefit of cloud-based hosting for companies is the cost-efficiency associated with outsourcing data operations, as the cloud helps to optimise energy costs and scalability. But there’s much more.

The cloud is a collection of purpose-built servers that are meant to perform one or multiple services ranging from storage, computing, database, web and email, and more. Cloud computing presents a number of key benefits for any type of company, small or large.

Apart from cost savings and scalability, businesses using the cloud can benefit from flexibility, as they can rent IT applications and services as required, instead of having to buy hardware and software assets outright. Another advantage is the universality of access to IT resources, which is enabled for any authorised users on authorised devices using an Internet connection.

When looking at cloud computing alternatives, the first question is usually whether your company should opt for public cloud, private cloud, or even a hybrid service.  We at Euro Systems have the expertise and solutions in hand to provide specialist advice and help you to implement the right alternative – but first, we will help you to understand the differences and benefits of these solutions before moving your business to the cloud.

What is the difference between public and private cloud?

The main difference between public and private cloud lies in the responsibility for data management and security; besides the distinction of who uses the servers and how they use them.

In a public cloud, the servers are shared among unrelated users, a.k.a. tenants, which is why public clouds are also called multi-tenant environments. You may have heard of Azure, but there are other big names for public cloud solutions, and they are characterised for off-site clouds typically owned by a vendor who sells access to servers.

With a public cloud hosting solution, you are not responsible for managing the data, as it is stored in the provider’s data centre, and the provider is in charge of managing and maintaining the data. Many servers provide services to many users – data is backed up regularly and customers pay for the resources they need and use. It is worth noting, however, that some cloud vendors expect users to hold responsibility for their own application level security.   

In a private cloud, on the other hand, the servers are owned by one user or a group of related users – therefore also known as single tenant environment. Within a private cloud, your data is protected by a company’s intranet or hosted data centre, behind a firewall. The servers are typically on-site, although they could also be off-site. In the private cloud, the owner is responsible for the management and maintenance of the servers, as well as planning for future performance and service availability, based on the users’ requirements.

When it comes to security, many companies feel that it could be lacking with a public cloud, but security breaches of public clouds are rare. The private cloud, however, does generally offer an increased level of security, as the resources shared with other businesses are very few, or non-existent.

Which cloud is right for you?

The decision is yours – and it’s down to control. A big company can decide that, because of their special computing needs, their data is best kept in the realms of a private data centre, and indeed, many large companies choose a private cloud. But large businesses are increasingly using public cloud services, so it largely depends on a company’s budget and circumstances.

A public cloud usually appeals to businesses that don’t yet require a dedicated data centre and can remain flexible with regards to their data hosting requirements.

There are some companies within specific sectors that may be regulated for data hosting, so the decision on whether to host in public or private cloud may be subject to specific regulations. However, there are specialised cloud solutions that count with appropriate levels of security and management as required by regulated sectors. 

Hybrid Cloud: Could a combination be the answer?

For many companies, the best solution is a hybrid cloud. In this type of cloud, multiple cloud vendors can be used for different tasks, and data centres and infrastructure is spread out in locations to decrease the risks of disaster or service loss.

Hybrid cloud is essentially a combination of on-site and off-site IT resources and different deployment types, public or private, which work with a level of integration. The hybrid cloud differs from multi-cloud in that the components work together in the hybrid cloud, while in the multi-cloud they work separately.

One of the key benefits for businesses using a hybrid cloud solution is the ability to quickly expand their storage capacity following any unexpected increases in demand, or during service outages.
