Journey to Cloud

Business Matter

Yes, money is a factor, in several ways.ROI is easier to forecast, and implementation costs are minimal.

Services can be easier and less expensive.It is scalable without breaking the budget, enabling both online and geographic

expansion.It lets an organization do more with less downtime, cost, and

It reduces infrastructure overhead

you want to do.

Cloud Migration Statergies Comparison

By 2011, Gartner stated 5 R’s for migration to cloud. By 2017, a new R was added.


Workload Placement

Cloud Hosting Ready - Gen 2

▪ Self-contained, virtualized, multi-tiered, web/thin client enabled

▪ Limited file system requirements/ leverage of cloud architecture & features (e.g. typical vertical scaling)

▪ Very aware of required OS/runtime environment and availability

Cloud Aware – Gen 2.5

▪ Modern applications, more componentized and more API centric

▪ App design can tolerate infra failures▪ Takes advantage of some cloud

features such as horizontal scaling or cloud based DR

▪ Micro-service _ 12 Factor App Architecture & Principles

▪ API first design▪ Design for Failure▪ Metrics & monitoring baked in▪ Horizontal & massive scalability▪ Cloud agnostic runtime

implementation

Cloud Native – Gen 3Traditional - Gen 1

▪ Legacy, monolithic applications▪ Deployed on Physical Infrastructure

and on Composable

Re-host Re-Architect Re-factorRetire Re-purchase Retain

Automated provisioning Workload portabilityNo vendor

lock-inPerformance and agility

Low total cost of ownership (TCO) Availability Scalability Security and compliance

Criteria to consider

▪ New Development ▪ Web Application▪ OpenSource RDBMS▪ Containerized Apps▪ Functions

▪ Application Servers▪ OpenSource RDBMS▪ Containerized Apps▪ Scale Out Workload

▪ Very Large RDBMS▪ Legacy COTS

▪ RDBMS requiring DR▪ Application requiring DR▪ COTS with specific certification ▪ Matrix (e.g. SAP/Oracle)


The Phoenix ProjectA novel about IT, DevOps and helping your business win


Cloud native means…

Use 12-factor app principles to create cloud native applications (12factor.net)

A set of best practices for developing and deploying cloud-native software

Practices translate into platform features and workflow requirements


Benefits of Infrastructure as a Code

Capgemini suggest to use Infrastructure as a Code methodology in order to provide high level of automation for the processes of design, build and deployment, all the infrastructure components whatever is possible will be represented using a modeling language (e.g. XML, Jason files etc etc)

▪ Build services around the business capabilitiesyou require

▪ Scale up and down as required with virtuallyno notice

▪ Make configuration code changes repeatableand standardized

▪ API-driven model enables management of infrastructure with language typically used in application code

▪ Free developers from manually configuring operating systems, system applications, and server software

Modernize existing .NET Applications

Author:Cesar de la Torre, Sr. PM, .NET Product Team, Microsoft Corp.

To optimize the cost-effectiveness of your organization's cloud migration strategy, it's important to consider the needs of your business and requirements of your apps. You'll need to determine:

▪ Which apps require a transformation or re-architecting.

▪ Which apps need to be only partially modernized.

▪ Which apps you can "lift and shift" directly to the cloud

XaaS – How to move your house?

Cloud Infrastructure-ReadyLift and shift

Cloud-AwareRe-platform

Cloud-NativeRe-platfom, Re-architect and re-write

Application's compute target

Applications deployed to VMs in Azure Monolithic or N-Tier apps deployed to Azure App Service, Azure Container Instance (ACI), VMs with containers, Azure Service Fabric, or AKS (Azure Kubernetes Service)

Containerized microservices on Azure Kubernetes Service (AKS), Service Fabric and/or serverless microservices based on Azure Functions.

Data target

SQL or any relational database on a VM Azure SQL Database Managed Instance or another managed database in the cloud.

Fined-grain databases per microservice, based on Azure SQL Database, Azure Cosmos DB, or another managed database in the cloud

Advantages

No rearchitecting, no new code Least effort for quick migration Least-common denominator supported in Azure Basic availability guarantees After moving to the cloud, it's easier to modernize even more

No rearchitecting Minimal code/config changes Improved deployment and DevOps agility to release because of containers Increased density and lower deployment costs Portability of apps and dependencies Flexibility of host targets: PaaS approaches or IaaS

Architect for the cloud, you get the best benefits from the cloud but new code is needed Microservices cloud-native approaches Modern mission-critical applications, cloud-resilient hyper-scalable Fully managed services Optimized for scale Optimized for autonomous agility by subsystem Built on deployment and DevOps

Challenges

Smaller cloud value, other than shift in operating expense or closing datacenters Little is managed: No OS or middleware patching; might use infrastructure solutions, like Terraform, Spinnaker, or Puppet

Containerizing is an additional step in the learning curve for developers and IT Operations DevOps and CI/CD pipelines is usually ‘a must’ for this approach. If not currently present in the culture of the organization, it might be an additional challenge

Requires rearchitecture for cloud native apps and microservice architectures and usually requires significant code refactoring or rewriting when modernizing (increased time and budget) DevOps and CI/CD pipelines is usually ‘a must’ for this approach. If not currently present in the culture of the organization, it might be an additional challenge
