Cloud Computing

What is Cloud Computing?

  • On-Premise

    • Less scalability (less flexibility)
    • Server Storage (have to maintain and power it)
    • Less Data Security
    • Data Loss (data recovery can be hard)
    • Maintenance have to be done by the company itself
    • Less collaboration

  • Cloud

    • More scalability (more flexibility)
    • Server Storage (have to maintain and power it)
    • Better Data Security
    • Data Loss (data recovery measures are there)
    • Maintenance
    • More collaboration (easier to share data in diff locations)

About Cloud

  • Delivery of on demand computing services on the internet
  • Pay-as-you-Go (pay more, scale up / pay less, scale down)
  • Cost efficient

Deployment Model

  1. Public Cloud
  • Like a bus
  • Lower cost (pay only for resources used)
  • Owned by Cloud Providers
  1. Private Cloud
  • Like owning a car
  • Managed by single organization or third party
  • Pay large amount up front (owned by the company)
  1. Hybrid Cloud
  • Using both
  • Like in Federal Agencies (store personal data, share nonsensitive data on public cloud)

Service Model

  1. IaaS
  • Infrastructure
    • Access to basic computing infrastructure
    • Commonly used by IT Administrators
    • Storage or VMs, Networking, Servers
    • Pay for What You Use
  1. PaaS
  • Platforms
    • Platform and runtime environments provided for Dev, Testing, Managing Applications
    • Commonly Used By Software Developers
    • Don’t have to acquire, manage, maintain related architecture
    • Only have to handle App and Data
  1. SaaS
  • Software
    • Involves hosting and managing software applications
    • Not owning any IT equipment
    • Commonly Used by End Customers
  • AWS
    • Services over the Internet
    • IaaS is their main
    • Subscriptions are pay what you use
  • Azure
  • Google Cloud Platform

Lifecycle of Cloud Computing Solution

  • Understand the requirements of the business (Define purpose)
  • Choose a compute service that will provide the right support where you resize the compute capacity in the cloud to run application programs (Define the Hardware ex. EC2, Lambda, Elastic Container Service)
  • Define Storage - Choose storage service for backup and archive data (S3, EFS, Glacier)
  • Define Network - securely deliver data, videos, applications, etc (VPC, Route 53, Direct Connect)
  • Define Security - user Auth, etc. (IAM, KMS, Cognito)
  • Define Management Processes and Tools (CloudWatch, Auto scaling, CloudFormation)
  • Testing Process - CodeStar, CodeBuild, CodePipeline (build, test, deploy code quickly)
  • Analytics - Athena, EMR, CloudSearch

Containers

  • Docker, Cloud Foundary, Kubernetes, etc.
