4. Azure Global Cloud

5. Modernizing web apps with Azure
No consistent service level/uptime.
No scaling if unexpected traffic.
Reduced agility/lack of flexibility.
Monolithic applications, legacy code.
Lack of resources for new initiatives.
Limited technical support.
Challenges App Service benefits
Built-in no-configuration auto-
scaling, load balancing and failover.
CI/CD/DevOps out of the box.
Serverless options for all app
scenarios.
Frees IT to focus on innovation.
Use existing skills, tools & frameworks.

6. What is a container?
Virtualize the hardware
VMs as units of scaling

7. What are microservices?
APP APP APP
Monolithic
Large, all-inclusive app
Microservices
Small, independent services
A Software Architectural Style
Applications are composed of small, independent modules
that communicate with each other using well-defined APIs.
Not platform specific.
Decoupled
These service modules are highly decoupled building
blocks that are small enough to implement a single
functionality but together can form larger systems
Independently versioned, deployed & scaled
With a microservices architecture, developers can create,
manage and improve application services independently,
even using different languages
Containers provide the consistent format and isolation
desired by microservices.

8. How can containers help your app modernization journey?
From traditional systems to a portfolio of modern apps

containers
Each host often runs

Seconds to
deploy, churns
12x faster1
Continuous innovation with DevOps
46x more frequent for code delivery2

Orchestrator’s cluster managing microservices &
containers
Clusters provide:
• High scalability
• Automatic High Availability and resiliency
• High services density per host

10. Containers in Azure
