Cloud computing explained: a guide for companies

In the context of digital transformation, flexibility, scalability and efficiency are crucial for businesses to succeed. Cloud computing has emerged as one of the most important technologies in this regard. But what exactly does the term “cloud computing” mean and why should companies consider investing in this technology for their IT infrastructure? In this article, we look at the basics of cloud computing, its advantages, challenges and how companies can benefit from using the cloud in the long term.

What is cloud computing?

Cloud computing describes the provision of IT resources such as computing power, storage and applications via the internet (“the cloud”) rather than via local servers or personal computers. The advantage? Companies can access these resources on demand and only pay for what they actually use. This reduces IT costs and increases flexibility.

There are different types of cloud computing:

• Public cloud: Resources are provided by third-party providers such as Amazon Web Services (AWS), Google Cloud, IBM® Cloud or Microsoft Azure and made accessible to multiple customers simultaneously via the internet.
• Private cloud: This is a cloud infrastructure that is operated exclusively for a company, either internally or by a third-party provider.
• Hybrid cloud: A combination of public and private cloud that enables companies to utilize the advantages of both approaches.
• Multi-cloud: Utilization of multiple cloud services from different providers to meet specific needs or avoid dependency on one provider.

There are also various service models (cloud computing services):

• Infrastructure as a Service (IaaS): Provision of virtual machines, storage and network infrastructure that can be scaled flexibly.
• Platform as a Service (PaaS): Provision of a platform for the development, testing and management of software applications.
• Software as a Service (SaaS): Provision of software applications that can be used directly by users via the internet.
• Function as a Service (FaaS): Enables developers to upload individual functions or small sections of code to the cloud and execute them without having to worry about the underlying infrastructure. FaaS is based on the concept of “serverless” computing, where the servers are managed entirely by the cloud provider.

Advantages of cloud computing

Cloud computing offers a number of advantages that enable companies to make their IT infrastructure more efficient and flexible:

• Cost efficiency: companies no longer need to invest in expensive hardware and data centers. Instead, they can rent cloud resources on demand and only pay for what they actually use. This significantly reduces both upfront costs and ongoing operating costs.
• Scalability and flexibility: Cloud computing enables companies to flexibly adapt their resources to current requirements. Whether in the event of an unexpected increase in user numbers or seasonal fluctuations – the cloud grows and adapts dynamically.
• Accessibility and mobility: With cloud computing, employees can access company data and applications from anywhere in the world. This not only promotes mobility, but also collaboration in globally distributed teams.
• Security and reliability: Cloud providers invest heavily in the security of their infrastructures. They often offer higher security standards and backups than many companies could implement themselves. They also ensure that services are always available and downtimes are minimized.

Challenges and risks

Despite the numerous benefits, there are also challenges that companies should consider when using cloud computing:

• Data security and data protection: outsourcing data to the cloud raises questions about security and the protection of sensitive information. Companies must ensure that their data is protected in accordance with applicable regulations and can only be accessed by authorized persons.
• Dependence on the cloud provider: Companies can become dependent on a particular cloud provider (vendor lock-in), which can limit flexibility and increase costs in the long term. Careful planning and the choice of a multi-cloud approach can help to minimize this risk.
• Cost transparency: The complexity of cloud cost models can make it difficult to keep track of actual costs. It is important to continuously monitor how cloud services are being used to avoid nasty surprises in monthly bills.

Data management in times of new work

Another crucial aspect of cloud computing is efficient data management. The digitalization in companies as well as changes in the way we work lead to more and more companies relying on decentralized teams, hybrid working models and remote work.

Secure and fast access to data plays a key role in this respect. Cloud solutions make it possible to store data centrally and at the same time make it accessible worldwide, which makes collaboration in teams much easier. However, IT security and data protection must not be ignored.

Especially in collaborative environments, it is important that all data is securely encrypted and protected against unauthorized access. By using modern cloud technologies, companies can overcome these challenges and offer their employees a flexible and secure working environment.

Cloud computing in action

The use of cloud computing in the real world shows how versatile and valuable this technology can be. Here are a few examples:

• Financial sector: banks use cloud services to efficiently process huge amounts of data while meeting high security requirements. Cloud-based analytics enables them to respond to market changes in real time and offer customized financial products.
• Healthcare: Hospitals and clinics use cloud solutions to securely store patient data and make it available at all times. This improves patient care and enables doctors to make quick and informed decisions.
• Manufacturing: Manufacturing companies use cloud-based systems to optimize their supply chains, monitor production processes in real time and increase efficiency through automated processes.

Future trends such as the increasing use of artificial intelligence (AI) and machine learning in the cloud, the further development of edge computing and the growing importance of multi-cloud strategies show that cloud computing will continue to be a driving force for innovation in the coming years.
