High-Availability Concerns

From Next-Generation Data Center

This part of the course focuses on high-availability aspects of modern data center designs and deployments:

  • How to define high availability
  • Dispelling the high availability myths
  • Identifying real business needs and their viability
  • Deciding what’s feasible to do based on application architecture, and what makes sense to deploy;
  • Security in private and public cloud environments;
  • Impact of modern application deployment processes on security and high availability.

Spring 2018

While many security professionals have a solid understanding of how to identify vulnerabilities in traditional physical infrastructure or applications, they often don’t grasp modern DevOps environments that include microservices, FaaS and IaaS. This leads to gaps, inefficiencies and a flawed program. Instead, security teams often distrust and deride the DevOps model that seeks to deploy at speed and scale, creating a narrative that does nothing to address the business need.

If organizations really want to deliver secure services, Information Security professionals have to meet DevOps and CloudOps teams where they are, by understanding how to embed security into their processes. This session by Michele Chubirka will help you shift the conversation – you’ll learn some DevOps concepts, the challenges faced in a continuous delivery environment and discover how to get Dev, Ops, and Security teams aligned and focused on a singular goal.

Spring 2017

Let's assume you want to increase the availability of your services by moving parts of them into the cloud or doing some sort of active/standby deployment between your DC and the cloud. Now you have to deal with your (C)ISO and his/her usual concerns as well as the variety of articles on tech sites stating that "security is the biggest challenge of cloud adoption". Matthias Luft (ERNW Research) broke those security concerns into categories (such as isolation failures, cloud outages, or compliance issues), looked at incidents and vulnerabilities from the past, and explained what we can do about those in our cloud strategy.

Autumn 2016

Ethan Banks (PacketPushers.net) talked about real-life aspects of active/active data center designs and lessons he’s learned while operating them.

Self-study materials

You’ll have to understand the basics of application architectures and load balancing. Watch:

I would also recommend watching parts of the IPv6 access to IPv4 content part of the IPv6 Transition Mechanisms webinar (40 minutes)

Additional recommended materials

You might want to know more about over-the-top cloud networking solutions. You’ll find them in the Cloud Computing Networking webinar (video Over-the-Cloud Networking).

These Expert Express Case Studies cover select details of active/active data centers and workload migration. Plan to spend an hour per case study.
