Hybrid Cloud: How to Avoid Twice the Problems

Avatar photoBy: Mark Nunnikhoven on August 8, 2016 Leave a Comment

Regardless of how enthusiastically you embrace the cloud, unless you’re a brand new business, you have already have an infrastructure running your applications. Odds are, you’re either renting space in one or more data centers. Or maybe long ago you reached the tipping point and built a data center or two of your own.

Regardless, moving to the cloud is going to be a process. You’re going to be working on a scale of months, if not years. During that time, how do you manage and secure assets that are in more than one environment—especially when those environments are radically different?

The Data Center

Your data center environment is probably well-established. You’ve got a mature technology stack, a high level of rigor around manual processes and a traditional “castle walls” perimeter-based approach to security.

Specialized teams are in place for the networking infrastructure, operating system management, security, data center logistics and other areas. Each team does a great job running the day-to-day of their areas and planning for the five-to-seven-year life cycle of their technologies.

The challenge here is that this structure has lead to a slow, stable cadence around innovation and encourages each team to work in their own silo. Common ground and management is established through a formal change management process. This results in stability, but at a very high cost when it comes to rapidly iterating on ideas.

The Cloud

In stark contrast, the cloud is constantly changing. New technologies are deployed quickly, systems such as continuous integration/continuous deployment (CI/CD) enforce what used to be a manual process and capacity planning is basically a thing of the past.

Just as the cloud is delivered in a different manner, teams working in the cloud also are delivering in a very different manner.

When assets are available on demand and at a higher level of abstraction, a lot of the work associated with deploying a new application is handled by automation, allowing you to focus on solving problems for your customers.

Reconciliation

It’s clear that the data center and cloud are two very different environments. How do you reconcile having assets in each without simply duplicating all of your tooling and processes?

Tools

Start with the tools that your teams are using today. Odds are, the set of tools you’re leveraging in the cloud more closely aligns with what you want to achieve around application delivery.

Cloud-first tools also are more likely to be able to handle the rapid pace of change and the large-scale environments normal to the cloud. These traits make it easier for cloud-first tools to adapt to the data center.

Make sure you’re pushing your cloud-first tools in to the data center and not the other way around.

Responsibilities

Leveraging more cloud services from a variety of providers means that the day-to-day operational and security responsibilities are spread out among teams and organizations. This can pose some serious challenges if not addressed properly.

You need to ensure responsibilities are defined clearly for all involved and there is a spirit of cooperation so that you can avoid finger-pointing when things hit the fan.

Remember that service level agreements (SLAs) represent the worst-case scenario. Solutions and services always should beat the stated SLA. If a team or organization you’re working with is consistently blowing their SLA or barely meeting it, it’s time to re-evaluate their involvement.

Process

Your processes define how the responsible teams are going to use the tools you’ve deployed. Data center processes are the weak spot in joint hybrid environment processes.

The traditional workflows typically are too slow and require too much manual work to support the style of work the cloud promotes. Take the processes you use in the cloud (think CI/CD), map out where you absolutely have to make exceptions for the data center, and use those as your baseline processes.

The goal here it to double down on your DevOps culture shift and force it into the data center. You want to maximize your current data center investment while not slowing down the culture transformation you’ve started with DevOps.

Security

The last piece of the puzzle (at least a high level) is security. It’s crucial you view security as a unified layer across all of your environments.

Security is challenging enough without creating additional work for your teams.

Security controls need to integrate with your preferred cloud service providers and be applicable inside the data center. The traditional perimeter is gone, and tools that still try to defend your data under that principle are needlessly increasing your risk.

Modern controls need to be applied as close to the workload and data as possible. They need to present a unified front across environments and still handle the speed and scale of the cloud.

That may seem like a tall order, but there’s a lot of work being done in the vendor and open-source communities to modernize the approach to hybrid security rapidly.

The Way Forward

Even in a best-case scenario, you’re going to be dealing with hybrid environments for months–if not years–to come. Doubling your workload or ignoring the challenges will only make matters worse. It’s best to tackle the problem head on.

Here are the three keys to remember:

  1. Aim for one set of processes,
  2. Push cloud tools into the data center, and
  3. View security as a unified layer.

This is a difficult task. You are not going to get it right the first time. The key is to ensure your teams are working together, communicating regularly and iterating often.
