🧊 Ice Breaker:

What people like about the cloud/their cause to learn more:

1. To expand their technical skills (Learn more about the subject)
2. The ability to launch computing resources with code
3. Love the serverless design of the cloud

🏎️ Fast facts:

• The value of the industry
  • 94% of enterprises use cloud services.
  • 70%+ companies intend to increase their cloud budgets.
  • Projected to be valued at $832.1 Billion by 2025.
• Some Companies have a mix of cloud and on-prem. Some companies are purely cloud based.
• Cloud is practically limitless in resource and potential.
• Cloud computing is designed with security in mind, implementations are naturally pro-security (authenitcation at every step).
• Cloud has been a major part of supporting remote work from a technical perspective.

✏️ Definitions:

What is cloud computing:

• A model to enable access to resources via the internet
• More features/constraints make it more specific, generally a way of enabling computing resources via the internet.
  • Typically recognized as easy to use, powerful, and scalable.
• What is a Computing resource?
  • Computing resources can vary for different people and different needs.
  • Can be storage solution
  • Can be a database
  • Can be a general program hosting service
  • Can be a entire platform to host your product
  • ...

🏢 Real world applications of the cloud:

• Data recovery, disaster recovery
• Website hosting
• Big data analytics & ML through the cloud infrastructure
• Software dev (Remote work, development vs. production development, segmentation of resources, etc)
• VDI
• CDN
• IoT
• Video and auto streaming
• Email and productivity apps
• CRM and ERP systems

☁️ Cloud Computing Models:

Public Cloud

• Provided through vendors like Amazon, Microsoft, Google, IBM, & Oracle Private Cloud
• Also provided by similar vendors.
• These are reserved spaces within the cloud the are partitioned/separated from other parts of the cloud.
• They are dedicated to a single organization. Hybrid Cloud
• A mixture of public + private cloud
• Offers more flexibility and availability
• Distribute workload depending on sensitivity

IaaS (Infrastucture as a Service):

• Third-party provider hosts and maintains the infrastructure:
  • Storage
  • Servers
  • Networking
  • Virtualization
  • etc.
• Typical to rent infrastructure and run your applications.
• Examples:
  • AWS (Amazon Web Services)
  • Microsoft Azure
  • GCP (Google Cloud Platform)
  • IBM Cloud
  • Oracle Cloud

PaaS (Platform as a Service):

• Third-party provider offers a platform for users to build, deploy, and manage their applications.
• Offer tools & services for application development, deployment, & scaling.
• Also include middleware, databse management, etc.
• Examples:
  • Heroku
  • Google App Engine
  • Microsoft Azure
  • AWS Elastic Beanstalk

SaaS (Software as a Service):

• Third-party provider hosts and delivers software applications over the internet.
• Access applications through the web browser or API.
• Provider manages all aspects:
  • Software
  • Maintenance
  • Security
  • Upgrades
  • etc.
• Examples:
  • G-Suite (Gmail, Google Drive, Google Docs, etc)
  • Microsoft 365 (OneDrive, Outlook, Word, PowerPoint, etc)
  • Dropbox
  • Zoom
  • Slack
  • Adobe Creative Cloud
  • ...

📊 Pros & Cons

IaaS Pros

• Scalability
• Pay as you go
• Easy to manage
• Geographical flexibility

IaaS Cons

• Security Risks (Someone else's infrastructure)
• Dependency for availability of computing resources
• Complexity in management (steep learning curve to manage resources)
• Custimization restrictions to infrastructure design

PaaS Pros

• Quick Deployment
  • Automation with a CI/CD pipeline enables quick, fast, and automated deployment.
• Scalability
  • Capable of responding to resource needs based on traffic, computational complexity, or any dynamic resource needs.
• Cost-effective
  • Pay as you go model ensures you pay for only how much you use, not for just keeping the servers running.
• Easy collaboration
  • Through the availability of shared computing resources on teh cloud
• Reduced complexity of managing infrastructure
  • Shared resources and easier centralization of resource allocation enables easier management.

PaaS Cons

• Limited Control of infrastructure
  • Products can be limited in design and functionality due to the platform's capabilities.
• Vendor lock-in
  • Similar to a stragety that Apple uses.
  • Too dependent on a particular Cloud ecosystem that can become tech debt or a financial burden.
• Security concerns on infrastructure
  • Your code is running on someone else's infrastructure.
  • Although, most cloud security breaches are caused by human sourced errors rather than any technical issues.
• Customization limitations
  • Limitations to the workings of the infrastructure.

SaaS Pros

• Low up-front costs
• Easily deploy + manage
• Accessible from anywhere
• Scalable

SaaS Cons

• Dependence on the provider
• Customization limitations
• Security concerns
• Integration Limitations

⚙️ Key Cloud technologies:

• Cloud Storage
• Databases
• Cloud Security
• Cloud Networking

🔬 Demo

Presented a short Discord Bot Demo using the power of AWS Lambda functions Current working implementation is available within Discord Bot channel as the API Alex Testing bot.
