Study Notes
Cloud Architectures
- Hybrid cloud combines public and private cloud
- Public cloud resources are shared among multiple users, logically isolated for each
- Private cloud resources are dedicated to a single organization
- Hybrid cloud combines private and public cloud, sharing data and applications
Public Cloud
- Definition: Cloud computing model where third-party providers manage resources (servers, applications, etc.) and provide these resources over the internet to multiple customers. Shared among users with logical isolation for each.
- Also known as hyperscalers (e.g., AWS, Azure, GCP)
- Key characteristics:
- Shared infrastructure (multi-tenancy) with isolated data and applications
- Scalable and elastic resources
- Pay-as-you-go pricing based on actual usage
- Managed by a provider, handles maintenance, updates, and security
- Global reach with data centers in multiple regions for low latency and disaster recovery
- Diverse service offerings (IaaS, PaaS, SaaS)
- Easy to use without requiring extensive technical experience
Public Cloud - Common Use Cases
- Startups and small businesses with limited budgets and IT expertise can quickly access infrastructure
- Application development and testing environments
- Data analytics and machine learning, handling large datasets
- Web hosting, e-commerce platforms, and e-commerce sites
- Disaster recovery and backup solutions
- Global collaboration and remote work, tools like Google Workspace, Microsoft 365
- Temporary or seasonal workloads (e.g., online retail during holidays)
Public Cloud - Limitations and Pitfalls
- Security concerns due to shared infrastructure and data privacy/compliance
- Limited control over infrastructure
- Network dependency, relying on consistent and high-speed internet
- Compliance challenges in specific industries (due to data sovereignty laws)
Private Cloud
- Definition: Cloud computing environment dedicated to a single organization.
- Exclusive access to computing resources, hosted on-premises or a third-party data center
Private Cloud - Key Characteristics
- Exclusive access, ensuring data privacy and control
- Customizable to meet specific organizational requirements (hardware, software, and security policies)
- Enhanced security, ideal for industries with strict compliance
- Scalability can be limited compared to public clouds due to physical hardware constraints
- Requires a higher upfront investment but can lead to cost savings for predictable workloads
- Control and ownership of infrastructure, software, and data
- Location flexibility, can be on-premises or hosted by a third-party provider
Private Cloud - Common Use Cases
- Industries with regulatory compliance requirements (healthcare, finance, government; HIPAA, PCI DSS)
- Data sovereignty and control (specific geographic regions)
- Custom application hosting needing specific setup/configurations not available in public clouds
- Enhanced security needs, minimizing multi-tenancy issues
- Workloads with stable demand (where scaling benefits are less critical)
Private Cloud - Limitations and Pitfalls
- Higher upfront costs if deployed on-premises
- Complex infrastructure management requiring in-house expertise
- Scalability limitations due to physical hardware
Hybrid Cloud
- Definition: Cloud computing model combining private and public cloud environments. Allows data and applications to share between them, enabling scalability, cost efficiency, and control.
- Companies leverage the strengths of both private and public clouds
Hybrid Cloud - Key Characteristics
- Integrated environments, seamlessly connecting private and public clouds for unified infrastructure
- Flexibility in moving workloads based on performance, cost, or compliance needs
- Scalability leveraging public cloud's dynamic scaling while keeping sensitive data in private cloud
- Security and compliance: sensitive tasks in private cloud, non-critical tasks in public cloud
- Cost optimization: offloads specific workloads to public cloud avoiding over-investment in private infrastructure
- Centralized management tools for managing resources across both environments
- Disaster recovery/redundancy by distributing resources across multiple environments for better option
- Interoperability enabling smooth data and application transfer between private and public cloud resources
Hybrid Cloud - Common Use Cases
- Dynamic or seasonal workloads to handle traffic spikes, retail during holidays
- Regulatory compliance, storing sensitive data privately while running cloud tasks in public
- Application development/testing: developers using the public cloud then deploying to private (production)
- Disaster recovery: public cloud as cost-effective disaster recovery sites
- Big data analytics: utilizing public cloud scalability (on less sensitive data)
Hybrid Cloud - Limitations and Pitfalls
- Complexity integrating different environments can be challenging
- Interoperability issues in ensuring compatibility
- Security challenges in data transfer between clouds, needing specialized security solutions
- Higher costs if cloud resources aren't managed appropriately
Software as a Service (SaaS)
- Software distribution where applications are hosted by a service provider, accessible via web browser.
- Subscription based instead of outright purchase (and installation)
- Examples include Google Apps (Maps, Gmail, Drive)
Infrastructure as a Code (IaC)
- Managing and provisioning infrastructure via machine-readable configuration files instead of physical hardware setup/configuration tools
- Provides many benefits, wide applicability
Security in Cloud Computing
- Shared responsibility model: cloud providers handle infrastructure, customers manage data and applications/access
- Shift from perimeter security to zero-trust: treat no user, device, or application implicitly trusting
- Implement identity-centric security: verifying users, devices, and applications before access to resources
- Encrypt data everywhere (at rest, in transit, in use)
- Leverage cloud-native security tools (by cloud providers) for security
- Automate security with DevSecOps tools (Infrastructure as Code, etc.)
- Continuously monitor and detect threats, including misconfigurations, unauthorized access
- Ensure compliance with regulations (ensure compliance standards like GDPR, HIPAA, PCI DSS)
- Protect against emerging threats in cloud computing (like misconfigurations, permissive roles, insecure APIs)
FinOps
- Definition: Cultural and operational practice to bring finance, IT, and business teams together to efficiently manage cloud costs. Emphasizes teamwork, transparency, and accountability.
FinOps - Benefits
- Cost efficiency: reduce unnecessary spending and enhance resource utilization
- Business agility: enable faster decision-making aligning spending with business priorities
- Enhanced collaboration between technical and financial teams
- Accountability: empowers teams for owning their spending
- Scalability: supports rapid scaling while keeping cloud cost in control
- Visibility and control: gives granular insights into cloud spending for better oversight
FinOps - Core Principles
- Collaboration: cross-functional cooperation to align cloud spending priorities, involves Finance, IT, and Business teams
- Accountability: teams responsible for their cloud resource consumption, encouraging efficient use
- Real-time Insights: continuous visibility into spending data enabling timely decisions
- Optimization and Value Delivery: balancing cost control with business outcomes
- Decentralized Execution with Centralized Governance: teams independently manage costs following guidelines
- Continuous Improvement: iterative processes to analyze, refine, and improve cost management
FinOps - Key Practices
- Cloud Cost Transparency: track and visualize cloud spending across services, teams, and projects
- Budgeting and forecasting: create realistic budget and future predictions
- Cost Allocation: allocate expenses to correct teams and departments fostering accountability
- Rightsizing Resources: Optimize utilization of cloud resources
