Cloud and Data Fundamentals, The Short Answer
Cloud computing delivers IT services, including servers, storage, databases, networking, and analytics, over the internet rather than through on-premises hardware. Data fundamentals cover how information is collected, stored, processed, secured, and analysed across cloud environments. Together, cloud and data represent one of the highest-demand competency areas in UK technology, with entry-level roles starting at £28,000 to £40,000 and senior cloud architects reaching £70,000 to £100,000 or more.
Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) collectively hold over 65% of global cloud infrastructure market share. UK public sector, financial services, and retail organisations have substantially migrated workloads to cloud platforms, creating sustained demand for professionals with cloud administration, cloud security, and data engineering skills. Cloud misconfigurations are among the most common causes of data breaches affecting UK organisations, making cloud security knowledge a non-negotiable element of any modern cyber security role.
The Cyber Security Online Degree Pathway (ODP 7733), a Qualifi Level 5 Extended Diploma in Cyber Security, addresses cloud security concepts including the shared responsibility model, encryption requirements, and access control design within its network security and risk management modules. Full programme details are in the Online Degree Pathways faculty.
Cloud Service Models and Deployment Architectures
Cloud computing is categorised by how services are delivered (service model) and where infrastructure is hosted (deployment model). Understanding these distinctions is foundational for any cloud or cloud security role.
| Model | What the Customer Manages | Examples |
|---|---|---|
| IaaS | OS, middleware, applications, data | AWS EC2, Azure VMs, Google Compute Engine |
| PaaS | Applications and data only | AWS Elastic Beanstalk, Azure App Service, Google App Engine |
| SaaS | User access and data classification | Microsoft 365, Google Workspace, Salesforce, Zoom |
| Public Cloud | Shared, multi-tenant infrastructure | AWS, Azure, GCP public regions |
| Private Cloud | Dedicated single-organisation infrastructure | On-premises VMware, Azure Stack |
| Hybrid Cloud | Mix of private and public workloads | Most large UK enterprise environments |
Security note: The service model determines how much of the security responsibility sits with the customer. In IaaS, the customer manages OS, network configuration, and application security. In SaaS, the provider handles all of this but the customer remains responsible for data, access management, and UK GDPR compliance. Understanding these trade-offs is a core cloud security competency.
Cloud Security Fundamentals
Security in cloud environments differs substantially from traditional on-premises practice. The shared responsibility model, new attack surfaces, and dynamic infrastructure all require specific knowledge and skills. Cloud security is a growing specialism with strong demand and premium salaries across the UK market.
The Shared Responsibility Model
AWS, Azure, and GCP each publish their own version of this model, but the principle is consistent: the provider secures the cloud (physical infrastructure, hypervisor, networking hardware); the customer secures what they put in the cloud (data, IAM configuration, operating system, application security). The dividing line shifts by service type, with IaaS placing the most responsibility on the customer and SaaS the least. Misunderstanding this boundary is one of the leading causes of cloud data breaches.
Identity and Access Management in the Cloud
AWS IAM, Azure Active Directory (Microsoft Entra ID), and Google Cloud IAM implement role-based access control. Best practice includes the principle of least privilege, enforcing multi-factor authentication on all privileged accounts, and regularly auditing IAM policies. According to the Cloud Security Alliance, misconfigured IAM is the primary attack vector for cloud-targeted intrusions, making IAM knowledge a critical skill for both cloud engineers and security practitioners.
Data Encryption in Cloud Environments
Data must be encrypted both at rest and in transit. AWS KMS (Key Management Service), Azure Key Vault, and Google Cloud KMS provide managed cryptographic key services. TLS is the standard protocol for data in transit. Under UK GDPR, organisations have a legal obligation to implement appropriate technical measures to protect personal data: encryption is the primary technical control for data protection compliance in cloud-hosted environments.
Cloud Security Posture Management (CSPM)
CSPM tools continuously monitor cloud environments for misconfigurations and compliance violations. Prisma Cloud (Palo Alto Networks), Microsoft Defender for Cloud, and AWS Security Hub are leading products, checking configurations against CIS Benchmarks and mapping findings to frameworks including ISO 27001 and NIST CSF. CSPM is increasingly a core function in cloud security engineering roles and is directly relevant to the risk management content in the Cyber Security Online Degree Pathway (ODP 7733).

Frequently Asked Questions, Cloud and Data Fundamentals
Which cloud platform should I learn first: AWS, Azure, or GCP?+
AWS has the largest global market share and the most mature certification pathway, making it a strong choice for the broadest employment options. Azure is the dominant cloud platform in UK enterprise environments, particularly those running Microsoft infrastructure, making it the most practical first choice for large UK organisation roles. GCP is strong in data and machine learning workloads. Most cloud professionals develop familiarity with two or more platforms across their careers. For a first certification, the AWS Certified Cloud Practitioner or Microsoft Azure Fundamentals (AZ-900) are the most accessible entry points.
What is the shared responsibility model in cloud security?+
The provider secures the cloud: physical infrastructure, hardware, and core services. The customer secures what they deploy on the platform: data, applications, identity management, network configuration, and operating system settings. The boundary shifts by service type: IaaS places the most responsibility on the customer; SaaS the least. Misunderstanding this division is a primary source of cloud security vulnerabilities and a leading cause of cloud data breaches globally.
How does UK GDPR apply to data stored in the cloud?+
UK GDPR applies to personal data regardless of where it is physically stored. Organisations using cloud services remain the data controller and retain full compliance responsibility. A Data Processing Agreement must be in place with the cloud provider. Transfers of personal data to infrastructure outside the UK require an appropriate legal mechanism, such as an adequacy decision or Standard Contractual Clauses. The ICO can issue fines of up to £17.5 million or 4% of global annual turnover for serious breaches.
What is serverless computing?+
Serverless computing is a cloud execution model where the provider dynamically allocates resources in response to function calls, charging only for resources consumed during execution. AWS Lambda, Azure Functions, and Google Cloud Functions are the leading platforms. Serverless is used for event-driven workloads such as processing a file on upload without provisioning a server. Security risks include function permission misconfiguration, dependency management vulnerabilities, and event injection attacks.
What cloud skills do cyber security roles require?+
Security analysts need to understand cloud-specific attack vectors such as misconfigured S3 buckets, over-permissioned IAM roles, and exposed APIs. Penetration testers use cloud-specific tools: Pacu for AWS, AADInternals for Azure. Security engineers implement CSPM tools, cloud-native security services (AWS GuardDuty, Azure Defender), and apply CIS Benchmarks to cloud configurations. CompTIA Cloud+ and AWS Certified Security Specialty validate cloud security knowledge at different experience levels.
What is the difference between a data analyst and a data engineer?+
A data analyst queries existing data to answer business questions using SQL, Excel, and tools such as Power BI or Tableau. A data engineer builds and maintains the infrastructure, pipelines, and systems that analysts rely on, working with BigQuery, Redshift, Databricks, and orchestration tools such as Apache Airflow. Data analysts typically earn £28,000 to £50,000; data engineers earn £40,000 to £75,000. Both are in high demand across UK finance, retail, healthcare, and technology.
What is containerisation and why does it matter for cloud roles?+
Docker containers package applications and their dependencies into portable, isolated units that run consistently across environments. Kubernetes orchestrates containerised applications across clusters, handling deployment and scaling automatically. Together, these technologies dominate cloud-native application deployment. Docker and Kubernetes proficiency consistently ranks among the most sought-after skills in UK cloud engineering job listings, and understanding container security is increasingly expected in cloud security roles.
