Introduction to Cloud Computing

1. Introduction to Cloud Computing What is Cloud Computing? Cloud computing is the on-demand delivery of computing resources including servers, storage, databases, networking, software, and analytics over the internet (“the cloud”). Rather than owning and maintaining physical infrastructure, organizations can access these services through providers like AWS, Microsoft Azure, or Google Cloud on a pay-as-you-go model. This model allows businesses and government agencies to operate with greater flexibility, speed, and cost efficiency while focusing on innovation rather than IT maintenance. Evolution of Cloud in the Public & Private Sector Initially adopted by startups and tech companies, cloud computing has evolved into a strategic backbone for both private enterprises and public sector institutions. In the early 2010s, cloud services offered basic compute and storage. Today, they provide: ● Advanced AI/ML platforms

2. ● Zero Trust security frameworks ● Automated compliance reporting ● Edge computing and IoT integration For the federal government, programs like FedRAMP and DOD IL levels accelerated secure cloud adoption. In the private sector, cloud-native technologies now power everything from real-time customer service to global logistics and data-driven decision-making Why Cloud Adoption is Critical for Modern Enterprises Today’s enterprises face evolving challenges: cybersecurity threats, remote work demands, rapid digital transformation, and increased regulatory pressure. Cloud computing enables organizations to: ● Modernize legacy infrastructure without the capital expense ● Scale instantly based on demand ● Improve agility and respond quickly to market needs ● Deploy globally and collaborate securely across geographies Without cloud adoption, organizations risk falling behind in efficiency, innovation, and compliance.

4. Accelerate development cycles with cloud-native tools like AI/ML, containers, and microservices all while staying secure and compliant. Cloud Service Models Explained This section breaks down the key cloud service delivery models IaaS, PaaS, SaaS, and XaaS helping clients understand the differences, use cases, and value each brings to their digital transformation journey. IaaS Infrastructure as a Service What It Is: IaaS delivers fundamental computing resources such as virtual machines, storage, and networks via the cloud. You rent the infrastructure from a provider and manage the OS, apps, and data. Key Features: ● On-demand access to servers, storage, and networking ● Flexible and scalable infrastructure ● Users manage OS and applications Examples: Amazon EC2, Microsoft Azure Virtual Machines, Google Compute Engine Use Cases: ● Migrating legacy apps to the cloud ● Hosting websites and development environments ● Temporary compute needs (e.g., testing, data processing)

5. Earthling Advantage: We help clients architect secure, compliant IaaS environments including FedRAMP and NIST 800-53-aligned deployments with robust access control, encryption, and monitoring. PaaS – Platform as a Service What It Is: PaaS provides a managed platform where developers can build, test, and deploy applications without worrying about the underlying infrastructure. Key Features: ● Pre-configured environments for application development ● Includes OS, databases, middleware, and runtime ● Scalable and auto-managed by the provider Examples: Microsoft Azure App Services, Google App Engine, AWS Elastic Beanstalk Use Cases: ● Building cloud-native or mobile apps ● Developing APIs or microservices ● Rapid prototyping with DevOps integration Earthling Advantage: We support DevSecOps adoption in PaaS environments with built-in security, CI/CD pipelines, and compliance automation ensuring your applications are audit-ready from day one. SaaS – Software as a Service What It Is: SaaS delivers software applications over the internet. Users access software via browsers, while the provider manages everything else from infrastructure to updates and security. Key Features: ● Subscription-based access to ready-to-use applications ● Fully managed by the vendor

6. ● Accessible via web or mobile devices Examples: Microsoft 365, Salesforce, ServiceNow, Zoom Use Cases: ● Collaboration and productivity tools ● CRM and ERP systems ● Email, analytics, and customer service platforms Earthling Advantage: We guide organizations in evaluating SaaS vendor security, conducting FedRAMP reviews, integrating single sign-on (SSO), and aligning SaaS tools with enterprise compliance requirements. XaaS – Anything as a Service What It Is: XaaS is an umbrella term that refers to the broad expansion of cloud services where virtually any IT function can be delivered “as a service.” Key Categories of XaaS: ● DaaS – Desktop as a Service ● BaaS – Backup as a Service ● FaaS – Function as a Service (serverless) ● SECaaS – Security as a Service Use Cases: ● Outsourcing non-core IT functions ● Flexible consumption models for fast scaling ● Modernizing aging infrastructure through modular services Earthling Advantage: We design secure XaaS ecosystems tailored to federal and enterprise environments integrating cloud-native tools while maintaining strict compliance and governance.

7. Types of Cloud Deployments Choosing the right cloud deployment model is a strategic decision that affects cost, scalability, security, and compliance. Organizations must evaluate their business goals, regulatory requirements, and technical needs when selecting between Public, Private, Hybrid, and Community Cloud options. Public Cloud Overview: A public cloud is a shared environment provided by third-party vendors such as Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Services are delivered over the internet and resources are shared among multiple tenants. Key Features: ● Pay-as-you-go pricing ● Near-infinite scalability

8. ● Managed infrastructure and updates by the provider Use Cases: ● Startups and SMBs needing affordable, fast deployment ● Application development and testing environments ● Elastic computing and big data processing Considerations: Security, multi-tenancy, and compliance must be evaluated especially for organizations in regulated industries. Earthling Insight: We secure public cloud environments with layered controls, FedRAMP-ready frameworks, and hardened configurations aligned with NIST 800-53. Private Cloud Overview: A private cloud is a dedicated environment used exclusively by a single organization. It can be hosted on-premises or by a third-party provider but is not shared with other customers. Key Features: ● Greater control over data, architecture, and security ● Customizable infrastructure for specialized workloads ● Meets high-assurance compliance needs Use Cases: ● Government or DoD workloads with IL4/IL5 requirements ● Financial services or healthcare organizations with strict data privacy mandates ● Enterprises seeking full control over their cloud stack Earthling Insight: We architect secure private clouds on-prem, in government-authorized data centers, or in isolated VPCs built to meet FedRAMP High, CMMC, and FISMA standards. Community Cloud

9. Overview: A community cloud is a shared infrastructure designed for organizations with similar compliance needs or business objectives. Ownership and access are restricted to the defined group. Key Features: ● Collaborative cost-sharing ● Tailored to specific regulatory needs ● Often managed by a consortium or third party Use Cases: ● Multiple government agencies with similar FedRAMP or FISMA needs ● Research institutions collaborating on sensitive data ● Healthcare organizations with joint HIPAA responsibilities Earthling Insight: We design secure, compliant community clouds for consortiums, federal partners, and research groups with unified security postures and shared governance frameworks. Cloud Security & Compliance As organizations transition to the cloud, security and compliance remain critical pillars of a successful deployment. From safeguarding sensitive data to meeting federal mandates, cloud security is not optional, it's essential. Earthling Security brings deep expertise in designing secure, compliant cloud architectures aligned with strict regulatory frameworks such as FedRAMP, FISMA, NIST, and CMMC. Below are the foundational elements every organization must understand and implement.

10. Cloud Shared Responsibility Model Overview: In the cloud, security is a shared responsibility between the cloud service provider (CSP) and the customer. The division of responsibilities varies depending on the service model (IaaS, PaaS, SaaS). Responsibility Cloud Provider Customer ✅ ❌ Physical security ✅ ❌ Network infrastructure ❌ (IaaS) ✅ Operating system ❌ ✅ Identity access ❌ ✅ Data encryption Earthling Advantage: We guide clients in fully understanding and executing their responsibilities under this model, minimizing gaps and ensuring audit readiness. Identity & Access Management (IAM) Overview: IAM governs who can access what within your cloud environment. Without strict controls, cloud environments are vulnerable to breaches, privilege misuse, and data leaks. Key IAM Practices: ● Role-Based Access Control (RBAC) ● Multi-Factor Authentication (MFA) ● Least Privilege Principle ● Audit Trails and Access Logs Earthling Advantage: We implement secure IAM policies across AWS, Azure, and GCP using best practices including Zero Trust principles and continuous authentication.

11. Data Encryption & Privacy Overview: Data in the cloud must be protected both at rest and in transit. Encryption ensures that even if data is intercepted or compromised, it remains unreadable without the proper keys. Key Focus Areas: ● Encryption standards (AES-256, TLS 1.2/1.3) ● Key Management Systems (KMS) ● Tokenization and data masking ● Data residency and sovereignty controls Earthling Advantage: We help clients deploy encryption strategies that meet or exceed FedRAMP High and DoD IL5 requirements — including integration with native KMS and hardware security modules (HSMs). Compliance Standards: FedRAMP, FISMA, NIST, CMMC Overview: Compliance is mandatory for organizations working with government data or operating in regulated industries. We ensure clients meet and maintain compliance across frameworks like: FedRAMP (Federal Risk and Authorization Management Program) Mandatory for cloud providers serving U.S. federal agencies. Earthling provides end-to-end support including gap analysis, documentation, and 3PAO prep.
