Cloud computing is a tool you need to provide computing services efficiently and quickly. Which one should you choose if you want to handle different customer needs? Secure cloud needs to combine several areas, from servers to databases, network, software to analytics, as well as increasingly important AI mechanisms.

The right choice of cloud translates not only into the efficiency of technological processes, but allows real savings through usage efficiency and operating cost reduction. This is why the analysis and comparison of all the various cloud characteristics is key.

It is worth remembering that a cloud, whether for a small, medium or large sized business, must be primarily secure. That is why the right choice of software and resource provider is so important. Choosing proven brands ensures quality; experiments with businesses without any proven history may be risky.

Which different types of cloud are there?

Bear in mind that clouds are different: unifying this technology and reducing it to the same mechanisms is a mistake. Various cloud types are perfect for specific needs, deployment types or as elements of a bigger network architecture. Clouds can be divided into three types. Although they services the offer can be brought down to the same thing, they differ significantly in technical terms. What is the specific for each cloud technology? What to look out for when the software as a service is meant for a small business, and what becomes key for a large enterprise?

Public Cloud

This is one of the most popular options. Service providers offer external storage and sharing of computing resources over the internet. The use of public cloud to computing processes has many advantages, but also some downsides. In this case, the order operator is responsible for the overall operations, from maintenance to software or infrastructure development. From a business point of view, the issue of responsibility for all the processes formally owned by the cloud provider is secondary. However, cloud deployments based on public platforms carry certain risks. Sharing resources among all public cloud customers can e.g. decrease performance. It is also difficult to expect any sort of customisation in terms of prices or expectations.

Private Cloud

The option where a cloud is used only by a single entity makes it possible to significantly reduce the main disadvantage of public technology, which is access risk. In business terms, private platforms used by a single company retain complete privacy. They can be physically located e.g. on company premises. This translates into the certainty of data control. Other advantages include full control when creating an environment or adapting private cloud often to very specific customer requirements. The limiting factor could be resource constraints or the fact that developing a private cloud is time consuming.

Hybrid Cloud

An interesting combination of the possibilities offered by the public cloud and its private mutation. Hybrid cloud allows data and resource migration between the two cloud types. The effect is first of all versatility and better deployment capabilities. Flexible technology offers wide possibilities to adapt the cloud to current needs or security formats. Planned resource consumption is generated by the private cloud, and when it runs out, public cloud comes in.

This solution allows for cost optimisation and procedure adjustments, e.g. quick transfer of tasks and calculations to the public cloud when private resources are not enough. However, this process needs to be controlled in advance, computing power task requirements need to be planned earlier.

Multicloud

Unlike a typical cloud, multicloud is a computing environment that is not based on a single source, but multiple clouds. The use of resources from several suppliers allows, e.g., for specialised development. This covers the dividing separate clouds for data analysis and processing, archiving or other types of activities. This is a relatively new solution and its characteristics are not yet precisely defined. Multicloud can therefore be thought of as a kind of cloud experiment.

What are the differences between private, public and hybrid cloud?

Cloud diversity is based primarily on the resource customisation and, consequently, the effectiveness of task handling. Public cloud operations entails restrictions, in the case of the hybrid cloud, there is an uneasy issue of data migration to meet current needs. In this context, a private cloud designed to support a single entity gives more options, even though resource limits.

How do cloud differences translate into costs and fitness for business needs?

Cloud prices, depending on their specifics, can have radically different business costs. You should not look at them only from the budget perspective, but above all, how they match a specific business profile. Therefore, for example the IaaS, which is practically a virtual server with specific parameters, is a very basic option. SaaS, i.e. the use of functionalities and software, offers much wider capabilities. PaaS, a cloud without any intricacies of typical for network infrastructure, allows running and managing applications without any restrictions. As a result, when you deploy a cloud for a wide user group, it is relatively the best option.

What are the different cloud types and models?

Cloud service categories are four solutions known as a cloud-based compute stack. Although they are perceived as distinct types, their holistically perception and use in the context of resources, offers particular business benefits.

Infrastructure as a Service (IaaS)

The foundation of cloud computing services, particularly appreciated for its simplicity. Cloud users opting for the IaaS rent the network and externally created infrastructure. Cloud providers therefore provide the network, servers and the operating system. The offer also includes other components necessary for cloud operation. All within a fixed payment system based on current consumption.

Platform as a Service (PaaS)

PaaS cloud services rely on providing the full environment necessary to create and support applications with later management. This translates into task production process. Applications are carried out without formalities connected with preparation of infrastructure or database resources for production.

Software as a Service (SaaS)

An extensive service combination where the cloud infrastructure provider provides access to applications and infrastructure. In addition, they provide full service, from ongoing maintenance to data protection or updates. The process where a SaaS customer can access their resources in reduced to the internet only.

When choosing a cloud, you should primarily consider how you want to utilise the cloud. You need to assume different things when you need to generate a lot of data space, than for creating computing instances themselves. Therefore, it is essential to determine the intended use of the cloud. In this context, however, geolocation is also important. Legal considerations, or simply the nature of business, require that the cloud is physically located in a given country. Therefore, although the cloud might seem as an imaginary virtual project somewhere literary beyond user heads, it is a tangible and important technology in a geographical context.
