What is Cloud Computing?

The simple definition: Cloud Computing This is a model that provides computing resources as a service on demand. Instead of operating their own hardware in the office, users access external data centers via the web, allowing data to be stored centrally and scaled flexibly.

You know this from everyday life Google Drive,Dropbox, Microsoft OneDriveiCloud, Gmail, or Google Photos. Files, photos, and content are no longer stored on a single device, but are cloud-based and accessible from almost any computer, smartphone, or tablet. The cloud, or cloud computing cloud, is therefore not a mystical place, but a network of cloud servers in globally distributed data centers.

In the business environment, email servers, Salesforce, Asana, Jira, Microsoft 365 (since 2011), and CRM systems are considered typical cloud computing services. Large cloud providers such as Amazon Web Services (since 2006), Microsoft Azure (since 2010), and Google Cloud Platform (since 2011) dominate the market.

The difference to on-premises IT: Previously, companies had their own servers on-site. Today, virtual resources, storage space, software, and IT services are accessed via the internet. Cloud computing allows companies to reduce IT costs by eliminating the need for physical servers and software maintenance.

How does cloud computing work technically?

Cloud computing seems simple, but it is based on powerful IT systems in the background:

• Virtualization: A physical server in the data center is divided into many virtual machines using a hypervisor. These operate like separate servers with their own operating systems.
• Infrastructure: A cloud consists of servers, storage, network components and security services in locations such as Frankfurt, Zurich or Amsterdam.
• Access: Users access cloud services via browsers, apps, or APIs. Login, roles, permissions, and two-factor authentication control access.
• Redundancy: Data is mirrored across multiple zones or regions. If one location fails, the website or application remains accessible.
• Cloud storage: Cloud storage stores data as objects, files, or blocks. This makes data storage, backups, and databases scalable.

It enables access to data and applications via the internet. Cloud computing allows users to access the same files and applications from almost any device. Cloud servers are located in data centers distributed worldwide.

Important service models: “as a Service” (IaaS, PaaS, SaaS)

Cloud services can be categorized into three main service models: IaaS, PaaS, and SaaS. These service models differ primarily in how much responsibility lies with the provider and how much with the customer.

Model	Significance	Typical use
Infrastructure as a Service	Virtual servers, storage and network	AWS EC2, Compute Engine, Azure VMs
Platform as a Service	Development platform without operating system maintenance	Heroku, Azure App Service
Software as a Service	Ready-made software applications in the browser	Slack, HubSpot, Shopify
Infrastructure-as-a-Service (IaaS) allows companies to rent servers and storage from a cloud provider to build their own applications. They retain control over the operating system and applications.

Platform-as-a-Service (PaaS) provides companies with the tools to develop their own applications without having to worry about the underlying infrastructure. PaaS is ideal when developers want to quickly deploy, test, and launch new applications.

Software-as-a-Service (SaaS) allows users to access applications hosted on cloud servers without installing them on their devices. This is also known as Software on Demand. Examples include Google Workspace, Slack, and Shopify. The cloud provider handles updates and maintenance.

Function-as-a-Service (FaaS) allows developers to execute code in response to events without managing servers; this is known as serverless computing. AWS Lambda is a well-known example.

Cloud deployment models: Public, Private and Hybrid Cloud

Cloud types differ in terms of ownership, control, and compliance. Especially in the DACH region (Germany, Austria, and Switzerland), data protection, GDPR compliance, and data location are crucial.

Public Cloud: A public cloud is provided over the internet and operated by an external provider. Public cloud services are managed by third parties and offer high flexibility and scalability. Public cloud services are standardized, quickly available, and particularly well-suited for dynamically growing or changing workloads.

Private Cloud: A private cloud is a cloud environment operated exclusively for one organization or company. A private cloud service is dedicated to a single organization and offers greater control and security for sensitive data. Private clouds offer a high degree of control but are administratively complex and costly.

Hybrid Cloud: A hybrid cloud combines public and private cloud models. It allows organizations to meet compliance requirements while benefiting from the flexibility of the public cloud. Hybrid cloud enables organizations to keep sensitive data on private servers while utilizing public cloud resources for less critical tasks.

A community cloud is a special case where several companies use shared projects. A virtual private cloud is a secure and isolated private cloud within a public cloud. Multi-cloud means that organizations use multiple cloud providers simultaneously.

LikeMeASAP When choosing a cloud environment, pay attention to whether it suits website performance, SEO tools, web analytics, and security requirements.

Cloud Storage in Detail

Cloud storage is the part of the cloud that most people understand first: photos in Google Photos, documents in Dropbox, website backups in S3 buckets. Examples of storage services include Dropbox, Google Drive, and iCloud.

Cloud storage stores digital data, files, databases, backups, and videos on remote servers in data centers. The three main types are:

• Object storage: Ideal for images, videos, archives and large amounts of data, such as AWS S3 or Google Cloud Storage.
• File storage: Works like a network drive, for example Azure Files.
• Block storage: Suitable for databases, VMs and high-performance applications.

A distinction is made between public cloud storage, private cloud storage, and hybrid cloud storage. Advantages include scalability up to terabyte and petabyte ranges, redundancy, versioning, automated backups, and global access. Since 2020, its use for AI, machine learning, and big data analytics has also grown significantly.

Challenges remain, including latency, vendor lock-in, cost control, and encryption. Cloud computing allows companies to flexibly adjust resources as needed, without high upfront investments.

Security, data protection and compliance in the cloud

Cloud providers rely on comprehensive security standards and GDPR-compliant data centers to ensure data protection and data security. Typical measures include physical security, firewalls, zero-trust architectures, identity and access management, TLS, and AES-256 encryption.

Data transmission between the end device and the cloud occurs via encrypted connections (TLS) to ensure data security. For cloud services, access rights and security policies must be consistently implemented to comply with data protection and regulatory requirements.

Data location is crucial. Regions like eu-central-1 in Frankfurt or europe-west10 in Berlin/Brandenburg facilitate GDPR-compliant processing. Public cloud services, where files are stored in data centers outside the EU, are problematic for companies that must comply with the GDPR.

Cloud providers based in the US are subject to US law, which means they must hand over data to American authorities, even if the data is located on servers in other countries. Data privacy concerns arise particularly when data is stored in jurisdictions with different data protection regulations.

Storing personal data in the cloud requires companies to regularly verify compliance with data protection regulations. GDPR compliance requires companies to ensure their cloud providers have implemented appropriate security measures. Certifications such as ISO 27001 and BSI C5 are relevant, for example, those offered by German providers like IONOS or large hyperscalers with corresponding documentation.

One risk of cloud computing is unauthorized access to sensitive data, which necessitates robust security measures. Using cloud services presents data protection challenges, particularly regarding unauthorized access and data security during processing. Cloud computing can also lead to compliance challenges, especially for organizations processing sensitive or regulated data.

Advantages and challenges of cloud computing for businesses

Since 2020, an increasing number of SMEs in the German-speaking countries (DA-CH) have been relying on cloud solutions, driven by home office, remote work, and faster digitalization projects. The use of cloud services is a crucial factor for modern IT strategies.

The main advantages of cloud computing include high flexibility, cost savings, location-independent collaboration, and rapid scalability. Cloud services offer significant cost savings by eliminating hardware investments and providing high flexibility. Cloud computing shifts IT costs and workload for companies, as they no longer need to maintain their own servers.

Using cloud services can improve collaboration by enabling teams to work together in real time from different locations. Cloud computing leads to greater flexibility, as companies can access their data and applications from any internet-enabled device. The cloud enables location-independent access to data and applications.

Cloud computing enables flexible resource allocation to meet user needs. Another advantage is the centralized management of IT infrastructure by the cloud provider. Cloud computing allows for the rapid deployment of IT resources without long lead times.

The risks: Costs can increase with dynamic resources, a stable internet connection is essential, and vendor lock-in can occur. Cloud computing can lead to dependencies on service providers, which can be problematic in the event of outages or business closure. Therefore, the rule is: Don't blindly move everything to the cloud, but rather prioritize migration, implement a security concept, and monitor.
