You're Responsible for Resiliency of Your Public Cloud Deployment

Enterprise environments usually implement “mission-critical” applications by pushing high-availability requirements down the stack until they hit networking… and then blame the networking team when the whole house of cards collapses.

Most public cloud providers are not willing to play the same stupid blame-shifting game - they live or die by their reputation, and maintaining a stable service is their highest priority. They will do their best to implement a robust and resilient infrastructure, but will not do anything that could impact its stability or scalability… including the snake oil the virtualization and networking vendors love to sell to their gullible customers. When you deploy your application workloads into a public cloud, you become responsible for the resiliency of your own application, and there’s no magic button that could allow you to push the problems down the stack.

Public cloud providers give you plenty of tools to help you build a highly resilient application, from availability zones and regions to multi-level load balancing, storage replication and managed cloud services… but you have to use them the right way. Application teams that invested into learning how to do that would feel right at home, those relying on vendor magic will be totally lost.

Our Networking in Public Cloud Deployments online course will help you master this topic. We’ll start with requirements and definitions, inspect sample application architectures, revisit lessons learned operating a traditional well-designed mission-critical environment, and hear from Justin Warren how they apply to public cloud deployments.

Interested? There’s just one tiny detail to take care of: you have to register first… but don't wait too long, we are closing the registration on February 3rd.

  1. Amen! Public clouds don't put up with a lot of kludges enterprise admins are used to.

    Now every time I run into dreaded Microsoft Network Load Balancing (NLB), which is short is MS screwing around with Layer 2 and Layer 3 standards to provide a semblance of scale/redundancy, I love telling the administrators to stop using it because Microsoft doesn't even support it in their own Azure cloud offering! Let the application or a dedicated load-balancer handle it - please! :)

    I personally have less of a problem with vMotion - as for the most part it works as advertised without giving the network engineers too much headache. I was surprised to learn that LIVE vMotion is even supported between on-premise and Vmware on AWS Cloud - https://cloud.vmware.com/vmc-aws/faq#vmware-site-recovery - that's pretty crazy - I would love to know more details / mechanics about that!

    Looking forward to the course Ivan :)
