Cloud, defined...
“ Cloud Computing is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.”

Cloud service modelsToday’s apps must keep up with the speed of the app revolution
Cloud growth has reasons...
• Applications with a short lead time to delivery.
• Predefined services for developers.
• Scaling Apps up and down dynamically.
• flexible billing (pay-as-you-go).

Engineering Approach
focused on decomposing an application into single-function modules with well defined interfaces which are independently deployed
Operated by small teams who own the entire lifecycle of the service.
Microservices
For IBM and Business Partner Internal Use Only
A microservice is a granular, decoupled componentwithin a broader application
Monolithic application

Simplistically, microservices architecture is about breaking down large silo applications into more manageable, fully decoupled pieces

Advantages of microservicesIn a word: Independent• Single small team to develop and support.
• timeline/ language and technology is totally independent.
• Data Management is independent.
• Scales and fails faster and independent.
• New versions delivered independently of other services.

A standard way to package an application and all its dependencies so that it can be moved between environments and run without changes.
Containers work by isolating the differences between applications inside the container so that everything outside the container can be standardized.

What is Kubernetes?
• Container orchestrator
• Runs and manages containers
• Inspired and informed by Google's experiences and internal systems
• 100% Open source, written in Go
• Manage applications, not machines
• Rich ecosystem of plug-ins for scheduling, storage, networking
