Working with multiple technical teams, architects, security officers, managers and business users, reviewed and documented workloads, system dependencies and business requirements. Mapped workloads to the capabilities of Microsoft Azure for public, private and hybrid clouds.

Designed and configured Azure Virtual Networks (VNets), subnets, Azure network settings, DHCP address blocks, DNS settings, security policies and routing.

Deployed Azure IaaS virtual machines (VMs) and Cloud services (PaaS role instances) into secure VNets and subnets.

Designed VNets and subscriptions to conform to Azure Network Limits.

Exposed Virtual machines and cloud services in the VNets to the Internet using Azure External Load Balancer.

Provided high availability for IaaS VMs and PaaS role instances for access from other services in the VNet with Azure Internal Load Balancer.

Implemented high availability with Azure Classic and Azure Resource Manager deployment models.

Designed Network Security Groups (NSGs) to control inbound and outbound access to network interfaces (NICs), VMs and subnets.

Setup Azure Virtual Appliances (VMs) to meet security requirements as software based appliance functions (firewall, WAN optimization and intrusion detections).

Utilized NSGs for layer 4 Access Control List (ACLs) for incoming and outgoing packets.

Used firewall appliance where requirements call for layer 7 security models.

Leveraged VNET system routes and underlying route table that holds Local VNet Rules, On-premise Rules, Internet Rules and IP Forwarding as design basis.

Designed User Defined Routes with custom route tables for specific cases to force tunneling to the Internet via on-premise network and control use of virtual appliances in the customer’s Azure environment.

Associated routes with VNets via the route table per relationship constraints.

Managed IP Forwarding for VMs and role instances acting as virtual appliances.

Configured BGP routes to enable ExpressRoute connections between on-premise data centers and Azure cloud.

Led DevOps development of PowerShell command scripts, custom PowerShell C# cmdlets, Python, PHP, Ansible, Puppet and Chef to configure, verify and monitor: networks, security, routes, IP-Forwarding, VMs and cloud service roles..

Reviewed workloads, system dependencies, business requirements and security requirements to optimize the Azure subscriptions, VNet design, NSGs, routing, deployment model and resource groups. Designed choice architectures for IaaS VMs, PaaS role instances and SaaS applications appropriate for the workloads (operating systems, applications, databases), transaction volumes, performance goals and security concerns.

Utilized ASR (Azure Site Recovery), PowerShell and MVMC (Microsoft Virtual Machine Convertor) for on-premise to cloud migrations

Prepared capacity and architecture plan to create the Azure Cloud environment to host migrated IaaS VMs and PaaS role instances for refactored applications and databases.

Implemented a structured design process for creating a hybrid cloud architectures to include on-premise resources, networks, security, IaaS, PaaS, SaaS, and DaaS architectures. Leading the architects to iterate through design steps and tasks to identify dependencies and resolving design conflicts where a design decision made in a later step may conflict with a design decision made in an earlier step, repeating the process until all considerations are incorporated into the final architecture design.

Fifteen years’ experience with relational data modeling, data warehouse(DW) modeling, business intelligence(BI), extraction, transformation, and loading (ETL) for very large data bases (VLDB). Applied DW/BI concepts to manage and monitor accounts and resources in Microsoft Azure cloud.
