Introduction of AWS

Concept of tools and services

• Service covered

  • compute
  • storage
  • databases
  • analytics
  • networking
  • mobile
  • developer tools
  • management tools
  • IoT
  • security
  • Enterprise apps

• benefits of AWS

  • agility
  • elasticity (scale up and down dependent on demand)
  • cost-saving (no up-front cost)
  • deploy globally in minutes

• What is a client-server model?

  In computing, a client can be a web browser or desktop application that a person interacts with to make requests with permission to computer servers. A server can be services such as Amazon Elastic Compute Cloud (Amazon EC2), a type of virtual server. For example, suppose that a client makes a request for a news article, the score in an online game, or a funny video. The server evaluates the details of this request and fulfills it by returning the information to the client.

• The 7 R’s of common practice for migration

  1. Rehost

     recreating the on-premise network, just change the host on AWS

     • Automating with tools such as AWS Application Migration Service

  2. Replatform

     • involves modifying legacy software to perform better in the cloud
     • like rehosting retaining the core architecture
     • Marking targeted AWS cloud optimizations

  3. Relocate

     • like rehosting but on hypervisor level
     • specific to VMware cloud on AWS

  4. Refactor

  1. Retire
     • shutting off non-useful applications
     • reducing spend, management, and securtiy
  2. Retain/ revisit
     • keeping certain applications on-premises
  3. Repurchase
     • moving workflows to SaaS

• Cloud Architecture Best Practices

  1. Design for failure and nothing fails

  2. Build security in every layer

  3. Leverage different storage options

  4. Implement elasticity

  5. Think parallel

  6. Loose coupling sets you free

• 6-pillars Well-Architected framework

  1. Operational Excellence
  2. Security
  3. Reliability
  4. Performance Efficiency
  5. Cost Optimization
  6. Sustainability

• Migration process

  • adopt a Minimum viable product (MVP) to allow customers to see how to process. Start with basics and keep receiving feedback

• Modernization

  • benefit

    • significantly reduce TCO (total cost of ownership) for cost optimization
    • gain ability through automation
    • free up resources to drive innovation

  • Containers
