  Technology Stack to Azure Service Mapping:         On Premise Datastore to Azure IaaS & PaaS Mapping:   -On-premise to Azure IaaS and PaaS Data Store Mapping Recommendations -Existing “Core, Contain, and Sunset” applications are to be ported to Azure IaaS with using its current datastore to minimize cost and accelerate migrations -App on-prem apps are encouraged to migrate to directly to PaaS when it makes good business sense to do so -Selected strategic applications are to be Modernized to Azure PaaS, the remaining applications will be Optimized to run on Azure IaaS. -All new application and microservices are to be developed on Azure PaaS datastores with Cloud Native enablement. -All new applications and microservices are to select the most optimal datastore model (i.e relational, document, key-value, etc.) based on the application data profile, characteristics, shape, and/or size ( see Azure data store selection guide – https://docs.microsoft.com/en-

 Benefits of moving to the cloud : Faster deployment, Lower costs, Self-Service, Operational Simplicity, Innovations are the key pointers for cloud. Self-service capabilities: Shorten our time to market Cost effective and efficient Operational Simplicity Innovation at scale Types of Publi c  Cloud Services: IaaS, PaaS, SaaS. Public Cloud First Policies: 1) Public Cloud First for Non-Network Workloads 2) Security Controls 3) Network Integration 4) Deployment Governance 5) Cost Management, Optimization and Visibility Optimization Public Cloud Migration Strategy: Assessing >4K apps for migration Estimating 80% of the workloads assed will migrate  Represents >250K servers today Targeting 75% reduction in allocated compute memory resources. Migration approaches: Optimization : Optimize the app during Lift & Shift approach. Everything else not involving source code changes Examples: Re-host applications from IaaS to PaaS Right size compute and storage Consolidate multiple services

 Cloud Security Principals to follow: 1) Secure the Network 2) Protect the Data 3) Control the access: use generation for AUTH, provide least privilege's access 4) Monitor the Environment 5) Deploy architecture as a Code: mutable infrastructure deployment 6) Ensure allocation matches the demand There are the 5 Key Cloud DevOps Skills your team need to Successfully Perform 40 App Support Tasks in to Public Cloud: 1) Account and Subscription Security: Management of access to application workloads for groups and individuals.

 What should be Enterprise Automation strategies of tomorrow CIOs and IT leaders have spent months adapting to change and scaling new solutions at speed; thus, spending considerable effort and energy; often to the point of burn out. Much of this is due to the changing natures of infrastructure and the application landscape; as IT leaders scramble to go cloud first in enabling new forms of working and reimagining operating models. In a cloud-first and increasingly automated world, CIOs and IT leaders must pay close attention to how their infrastructure is utilized and managed; as well as how apps are delivered – securely and to their optimum utility. It is therefore no surprise that the collective realization is that -  strategic infrastructure standardization ,  modernization  and  automation  efforts will be critical for successful digital transformation. The key questions many CIOs and IT leaders continue to have are as follows: 1.       How to craft automation as an ongoing discipli

 Why Azure Databricks?  Since Azure Databricks is a cloud based service, it has several advantages over traditional Spark Clusters. Let us look at the benefits of using Azure Databricks. > Optimized Spark Engine : Data processing with Auto-scaling and Spark optimized for up to 50x performance gains. > Machine Learning: Pre-configured environments with frameworks such as PyTorch, TensorFlow and sci-kit learn installed. > Mlflow : Track and share experiments, reproduce runs and mange models collaboratively from a central repository. > Choice of Language : Use your preferred language, including Python, Scala, R, Spark SQL and .Net -- whether you use serverless of provisioned compute resources. > Collaborative Notebooks : Quickly access and explore data, find and share new insights and build models collaboratively with the language  and tool of your choice. > Delta Lake : Bring data reliability and scalability to your existing data lake with an open source transactional

 Terraform Learning Agenda: 1) Infrastructure as Code (IaC) 2) Terraform Fundamentals 3) Terraform State 4) Terraform Modules 5) Terraform Built-in Functions and Dynamic Blocks 6) Terraform CLI Understanding Infrastructure As Code (IaC) IaC allows you to define infrastructure in human and machine-readable code. Terraform is a tool which is cloud agnostic and enables you to do IaC. Benefits of IaC No more clicks – Write down what you want to deploy (VMs, apps…) as human readable. Enables DevOps – Codification of deployment means it can be version controlled enabling visibility and collaboration across teams. Declare your Infrastructure – Infrastructure, in case of Terraform, is written declaratively making it easy to read and understand. Speed, cost and Reduced Risk – No fat Fingers, immutable code, no deployment drift. Terraform Fundamentals Terraform – Another IaC tool, but why? a) Automate software defined n/w b) Interacts and take care of communication with control layer APIs
