Study Notes
Platform as a Service (PaaS)
- Allows development, running, and management of applications without the need for complex infrastructure.
- Example: Google App Engine for developing and hosting web applications.
- Use cases include application development, web application hosting, and API development.
Software as a Service (SaaS)
- Delivers software applications via the internet on a subscription model.
- Example: Microsoft Office 365 for productivity software through the cloud.
- Common applications include email services, Customer Relationship Management (CRM), Enterprise Resource Planning (ERP), and collaboration tools.
Cloud Deployment Models
- Public Cloud: Services provided by third-party cloud providers, accessible over the internet (e.g., AWS, Google Cloud Platform, Microsoft Azure).
- Private Cloud: Exclusive cloud infrastructure for a single organization, either managed internally or by a third party (e.g., an organization's own data center).
- Hybrid Cloud: Combination of public and private clouds allowing data and application sharing; used for sensitive operations and less critical tasks.
- Community Cloud: Infrastructure shared by a specific community or industry, such as government agencies.
Key Cloud Providers
- Amazon Web Services (AWS): Offers services like EC2 (Compute), S3 (Storage), RDS (Database), Lambda (Serverless). Example: Netflix utilizes AWS for content delivery.
- Microsoft Azure: Provides services including Virtual Machines, Azure Blob Storage, and Azure Functions. Example: LinkedIn uses Azure for service performance.
- Google Cloud Platform (GCP): Includes services like Compute Engine, Cloud Storage, and BigQuery. Example: Snapchat leverages GCP for operations.
Cloud Security
-
Security Challenges:
- Data breaches from unauthorized access.
- Data loss due to hardware failure or disasters.
- Account hijacking by malicious actors.
- Insecure APIs with vulnerabilities.
-
Security Solutions:
- Encryption: Protects data both at rest and in transit.
- Identity and Access Management (IAM): Controls resource access.
- Multi-Factor Authentication (MFA): Adds security beyond passwords.
- Regular Audits: Ensures compliance with security policies.
Cloud Storage
-
Types:
- Object Storage: Stores data as objects.
- Auto-Scaling: Automatically adjusts resources based on demand.
-
Tools:
- AWS Cost Explorer for managing costs.
- Azure and GCP tools for budget management and optimization.
Cloud Migration
-
Steps for Migration:
- Assessment: Evaluate current infrastructure.
- Planning: Define migration strategy (e.g., rehosting, replatforming).
- Execution: Migrate data and applications.
- Optimization: Improve cloud resources post-migration.
-
Migration Strategies:
- Rehosting: Lift and shift applications to the cloud.
- Replatforming: Optimize without altering core architecture.
- Refactoring: Rewrite applications for full cloud-native benefits.
Cloud Computing Best Practices
-
Security Best Practices:
- Regular updates and patches.
- Use IAM roles; avoid root accounts.
- Implement network segmentation.
-
Operational Best Practices:
- Continuous monitoring and logging.
- Automate processes using Infrastructure as Code.
-
Cost Management Best Practices:
- Monitor usage and set budget alerts.
- Utilize cost-effective storage classes and reserved instances.
Real-Life Cloud Computing Situations
- Startup with fluctuating demand: Utilize Public Cloud IaaS for scalable compute resources.
- Healthcare organization: Implement Private Cloud for secure patient data storage.
- E-commerce platform during sales: Leverage Hybrid Cloud for scaling resources.
- Rapid web application deployment: Choose PaaS to streamline development.
- Global content access with minimal latency: Use CDN within a public cloud.
- High-performance computing: Use IaaS in the public cloud for simulations.
- Moving legacy applications to the cloud: Opt for Rehosting in a Public Cloud.
- Temporary project resources: Utilize Spot Instances in the public cloud.
- Collaborative development environment: Implement PaaS for coding and testing.
- Big data analysis needs: Use Big Data Processing Services in the public cloud.
