Real-life technical decision points in using cloud & container technology:
Modernising the NHS
Simon Boichat - Lead Azure ArchitectRoss Smith - Technical EvangelistBen Coleman - Cloud Solution Architect
Commercial Partner
Civica’s Modernisation Journey
Civica Cost Master and SLAM
Used by 124 acute hospitals
Around 83% of the country
Processes around £70bn hospital revenue
per year
Costings are usually run monthly or twice a
month
Where did we begin?
Traditionally self hosted solution
On a single machine
Often under powered
Not resilient or highly available
Many different configurations
Manual deployments
What constraints did we have?
Fat client applications with a collection of
windows services and SQL server
databases
Limit the amount of code change
Commercially viable
Time to market was short
Enable the future
Where are we now?

Why this architecture?
Footprint ideal for containerisation
Kubernetes
SQL PaaS
Power BI
Azure monitoring capabilities
The future
Experiment with Azure Container
Instances
Unlock more services on the Azure
platform
Move to Service Fabric Mesh or AKS
Takeaways
Business need for a SaaS offering allowed
us to make this transition
Technology options in Azure made it easy
to modernise the products
Enable for the future
Azure Kubernetes Service
Kubernetes: empowering you to do moreThe de-facto orchestrator
Easily scale stateless services
Seamless integration with cloud providers
Extendable and pluggable
Auto scaling and any scale
Run stateful services with persistence
Health monitoring
Declaratively define applications
Rolling updates / versioning
Service failover and workload optimization
Secure with policies Role based access Multi-tenancy
Kubernetes

Node Cluster
Azure Kubernetes Service (AKS)
Managed Kubernetes
Docker / Container Runtime
Azure Kubernetes Service
• Microsoft managed
• Control plane free of charge
• Automated upgrades, patches
• Secured and hardened
• Easy & auto cluster scaling
• Self-healing

Focus On Your Code
Integrated monitoring with Container Insights
Role based access with Azure Active Directory
Kept in sync with upstream KubernetesLatest version available within 30 days of release
Range of networking scenarios, e.g. hybrid
Azure Dev Spaces – simplify Kubernetes development
Kubernetes – Better on Azure with AKS
Demo Smilr
Microservices Feedback App
Want to run Linux based workloads in containers
Want to use Kubernetes but not build & manage the infrastructure
Run traditional (e.g. MVC, 3-tier) apps unmodified or modern microservice architectures
Have fine grained control over compute, storage & network with a rich application deployment model
Remain framework, stack & platform agnostic

Journey to digital transformation
Migrate existing applications as-is to the
cloud, including using containers, to reduce
cost and enable DevOps deployments
New applications conceived and built
with the cloud in mind using
microservices architecture
Mesh “In The Flesh”
Run Windows based workloads in containers
Want to use Service Fabric but not build & manage the cluster
Lift, shift, and modernize .NET applications to microservices
Low latency storage with reliable collections and volume drives*
Scale services on a consumption model

Microsoft Kubernetes & AKS LifecycleOpen Source First
Open Source
• Upstream contribution to CNCF & Kubernetes
• Available in AKS as self install –‘Experimental’
Preview Feature
• Open source features brought into AKS
• Preview status but 1st party experience
GA
• Feature is GA and available in all regions
• ARM, CLI, portal support
e.g. Virtual Kubelet e.g. Cluster Auto Scaler e.g. Role Base Access Control
Question Outcome Notes
Standard web workload App Service Not optimised for density
Need Orchestration Kubernetes / SF
Need service to service
(i.e. microservices)
Kubernetes / SF
Windows Containers Service Fabric Mesh?
Happy to self manage
