Unleash Opportunities With Compute options on Azure
Welcome!
HOW DO I ASK A QUESTION?
- If you have a technical or content-related question, please use the Q&A window
- We will address the questions as they come in
CAN I VIEW THIS PRESENTATION AFTER THE WEBINAR?
- There will not be a recording of the session, slides will be shared in the GitHub repository
- Due to the PII we are not keeping the recording of the session
Agenda!
- Why Application Innovation is important?
- Decision Matrix for the compute options on Azure
- Overview of each compute services and recent updates
- Why you need to design differently on the cloud
- Reference Architecture
- Demo on Event Driven Scaling ( AKS + Azure functions)
- Kahoot Quiz
Traditional application has a set of challenges
Aging infrastructure
- Aging hardware, operating systems, and business applications in the datacenter can impact:
- Operational costs, effciency, and reliability.
- Capital expenditure requirements.
- Security, audit and reulatory compliance.
lack of agility
- Deployment time of new services
- Operation is time (and budget) consuming.
- Innovation is happening outside IT inside business areas.
Legacy applications
- Longer release cycles, monolithic and highly coupled architecture.
- Highly IT dependent
- Low application performance and time to market compromise business agility.

What is Cloud Native App Development?

Deploy as microservices |
Manage app withDevOpsprocesses & tools |
By 2020, 35% of production apps will be cloud native

Common cloud native scenarios
|
|
|
|
| Modernize business critical applications | SaaS delivery | Real-time telemetry | Geo-distributed applications |
Key Components of Cloud Native
| Resources | Description | |
|---|---|---|
| Containers | Tool to package your app, run it portably on different hosts in a consistent way. | |
| Serverless | Platform for running and scaling apps where almost all of the operations tasks are managed by the cloud provider. Optimized to let developers focus on code and business value. | |
| Kubernetes | Platform to manage and scale your app reliably (made up of containers) that may span many physical and virtual machines. A tool for operations, noet development. |
Azure: The Power Of Choice
Compute
Virtual Machines
- Ubuntu, Red Hat, Windows, SUSE, CoreOS
- DevOps Extensions with Chef and Puppet Multiple sizes
- Hundreds of items in marketplace
Container Service
The container advantage
Developers love Kubernetes

AKS: Simplify the deployment, nanagement, and operations of Kubernetes
| ICON | Description |
|---|---|
| Deploy and manage Kubernetes with ease |
| Accelerate containerized application development |
| Set up CI/CD in a few clicks |
| Secure your Kubernetes environment |
| Scale and run applications with confidence |
| Work how you want with open-source tools & APIs |
Scenarios for AKS
Microservices with AKS
Azure Container Registry
Azure Container Instances (ACI)
Azure App Service
Reference Architecture for Managed Web
| Kind | Architecture | Resources Stack |
|---|---|---|
| Basic Web |
| ✓Service plan ✓Deployment ✓Authentication ✓SQL DB ✓Diagnostics |
| Improving Scalability |
| ✓WebJobs ✓Cache ✓CDN ✓Other storages ✓API App |
| Improving Availability |
| ✓Hosting in paired region ✓Traffic manager ✓Geo-replication |
Serverless stands out as the technology
What is servierless?
| Full abstraction of servers Developers can just focus on their code - there are no distractions around server management, capacity planning, or availability. |
| Instant, event-driven scalability Application components react to events and triggers in near real-time with virtually unlimited scalability; compute resources are used are needed. |
| Pay-per-use Only pay for what you use: billing is typically calculated on the number of function calls, code execution time, and memory used.* *Supporting services, like storage and networking, may be charged separately. |
Azure serverless ecosystem
FaaS is the center of serverless
| ICON | Description |
|---|---|
| Single responsibility Functions are single-purposed, reusable pieces of code that process an input and return a result. |
| Short lived Functions don't stick around when finished executing, freeing up resources for further executions. |
| Stateless Functions don't hold any persistent state and don't rely on the state of any other processes. |
| Event driven & scalable Functions respond to predefined events, and are instantly replicated as many times as needed. |
Azure Functions Programming Model
Scenarios for Serverless
- Anything that needs to respond to events.
