In the digital age, when flexibility and scalability play a key role on the road to business success, cloud services are becoming an integral part of organizations’ IT strategies. By leveraging the benefits of cloud computing, companies can dynamically scale their IT resources, increasing operational efficiency.

Cloud computing: co to jest?

Introduction to IaaS (Infrastructure as a Service)

Cloud computing is a model for delivering IT services through a monthly subscription. It makes the provider’s resources and services, including computing power, disk space, virtualization, operating systems, databases, etc., available to the user via the Internet. In other words, it is a set of IT solutions that enable the provision of IT resources over the Internet. Instead of local servers and infrastructure, customers are given the option of using IT equipment housed in a professional data center. From a business point of view, the cloud can be described as IT infrastructure outsourcing, allowing access to advanced IT technologies without having to invest in one’s own infrastructure and expensive software.

Cloud computing providers enable cloud services in several models. The three most commonly referred to are Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). The models differ in terms of how the handling of the respective areas is shared between the service provider and the user and, as a result, what end product is made available to the user.

IaaS, or Infrastructure as a Service, is a cloud model that allows IT resources such as servers, networks, operating systems, or storage to be accessed as an online service. Unlike Platform as a Service (PaaS) and Software as a Service (SaaS), IaaS offers the greatest level of control over infrastructure, giving organizations complete freedom to manage their IT environments.

Key features of IaaS

Some of the key and most frequently cited features of the IaaS model are flexibility and scalability. Organizations can easily increase or decrease the number of resources used depending on their current business needs, allowing for optimal management of IT costs and resources. When companies decide to purchase their infrastructure, they have to face the estimation of the planned utilization of resources in the future, usually until the end of the amortization period or the end of services and technical support. In practice, a period of at least five years should be assumed. This is particularly difficult in industries associated with seasonality, both production and sales.

Another important feature of IaaS is the ability to fully manage and maintain the infrastructure. Users have control over operating systems, applications, and data, giving them greater freedom to tailor their IT environment to meet specific business requirements.

As part of the solutions provided, IaaS providers such as Polcom invest significant resources in ensuring data and infrastructure security, as well as meeting the requirements of market regulators, which is particularly important for companies operating in sectors regulated by separate legislation, i.e. finance or healthcare.

Benefits of IaaS for business

IaaS enables a significant reduction in operating costs by eliminating the need to invest in costly physical infrastructure. This means a shift from CAPEX to OPEX and the ability to implement IT projects, even in situations where companies are facing financial difficulties. The subscription model allows better management of IT budgets, eliminating unforeseen expenses related to infrastructure failures.

With the flexibility and scalability of IaaS, organizations can respond quickly to changing market and business needs. Companies associated with industries exposed to seasonality in production and sales can easily increase resources during the peak season, only to reduce them just as quickly once the season is over, reducing costs at the same time. This increases operational efficiency and allows for rapid deployment of new projects and applications. Thanks to cloud technology, IT managers have the opportunity to increase the retention of their specialists, as well as redeploy them from more creative tasks and give more value to the organization, such as those related to business application development.

IaaS supports the growth of companies on various levels. The aforementioned lack of need to invest in their own IT infrastructure and software licenses lowers the barriers to entry for small and medium-sized companies. Among other things, this makes it possible for start-ups to focus on innovation and product development, while offering a high level of security for their services. Large corporations, on the other hand, can use IaaS to scale their operations on a global scale, ensuring business continuity and high service availability.

How does IaaS work?

The architecture of a typical IaaS platform consists of several key components, such as virtual machines (VMs), storage, and internetworking (networking). These resources are managed by the IaaS provider and made available to users on-demand in the form of a monthly subscription.

The wide range of resources includes different types of virtualizers, storage resources, or computing power, which are selected according to the customer’s technological requirements and budget. This allows any IT project to run smoothly, as users can configure these resources according to their business needs, enabling the creation of advanced IT environments.

The process of setting up an environment in the IaaS model usually involves several steps: selecting the appropriate computing resources, such as the amount of vCore, vRAM or a specific type of storage, and possibly selecting an operating system. To this is added the configuration of the network and security elements, and then the deployment of the application. Thanks to intuitive tools and user interfaces, this process is usually simple and fast.

As one of the leading IaaS providers, Polcom stands out from the competition with its project-based approach, which means adapting to the customer’s needs. We deliver bespoke projects something hyper-scalers don’t do and don’t want to do. Polcom does not provide a mass service, but one that is tailored to the customer’s project requirements. Polcom’s data centres not only meet but often exceed, international security and quality standards. The data centres are equipped with the latest technology to ensure high availability and continuity of IT services, which is crucial for global business projects. Each centre has been developed with maximum security and energy efficiency in mind. Thanks to these features, Polcom earns the trust of both small businesses and large corporations by offering reliable and scalable IaaS services.

The future of IaaS

The future of IaaS services seems very promising, with predictions of further growth and adaptation across a variety of business sectors. The growing demand for flexibility and scalability in IT infrastructure management is driving more and more companies to move their resources to the cloud. Technological innovations such as artificial intelligence and automation will further enhance the management and optimization of resources in the cloud. In addition, developments in edge computing and 5G will enhance IaaS capabilities, allowing even faster and more efficient processing at the edge of the network. Increased awareness and improved security standards will also be key to minimizing the risks associated with storing and processing data in the cloud.
