Hybrid Cloud

Why would you do this? Want to leverage existing investments Locked in to existing provider Running things that are not supported in Azure Windows Server 2003, Windows Server 2008, SQL 2005, RHEL and more Roles/Features not supported in Azure:

Things to consider What workloads can and/or should be in Azure? New workloads, temporary workloads, elasticity needed, core services What’s the right “somewhere else” for me? Current investments, needs of the business (e.g. self-service), support requirements How do I connect? Scope, volume of traffic, performance requirements, SLA requirements

Things to consider for Public Cloud How do I keep it secure? You can’t deploy physical firewalls like you do in your own datacenter. How do I manage it? You want a consistent tool set that can span across your chosen Clouds

Some of our Hybrid Cloud Learnings Connectivity Even if your bandwidth requirements are not great, ExpressRoute gives you lower latency and Carrier applied QoS. Avoid static routing VPNs except in very simple scenarios. As soon as 2 connections are needed to 1 vNet dynamic routing required. To switch from static to dynamic you need to destroy and recreate the gateway. Downtime! Fewer Firewalls have support for Dynamic Routing, but an RRAS Server will work just fine.

Some of our Hybrid Cloud Learnings PPT – People Processes Technologies Is your organisation ready for adopting Hybrid Cloud? Are the people you already have adequately skilled in taking full advantage of Public Cloud? Do you have processes that are tied to Legacy / Physical / Virtual environments inside your datacentre? Do your service management systems work and scale like Public cloud does?

Some of our Hybrid Cloud Learnings Windows Azure Pack/Windows Azure Stack You will have different consoles for managing private and public clouds Pay close attention to prerequisites Network design is paramount. Connectivity between WAP vNets and outside world is managed by Gateway hosts and VMs. Supports multiple VPNs or one ExpressRoute. If you want to maximize the Azure footprint, Design VMs around as many of the Azure limitations as you can. E.g. drive sizes, DHCP

Our Scenario Going to run a scalable web front end in Azure… …Accessing a backend which isn’t supported to run in Azure.
