Continuous Infrastructure

How IT Went from the Back of the Class to the Front of the Board Room

Businesses have IT because apps deliver value to their customers. This can be direct value - a user-facing app. Or it can be indirect - an internal app for managing sales, marketing, or even HR transactions. Either way, the idea is that the app will make the business more efficient and responsive.

The purpose of IT used to be to develop, purchase and operate these apps. But today, every team in the business is writing apps, and every part of the business depends on the apps that they run. These apps have gotten bigger. They have become more complex. There are more apps everywhere, and they are more mission critical than before.

In fact, we are long past the point where any modern application is a single piece of software. Most apps these days run on top of a collection of common services - such as web servers, database servers, queue servers - even the storage space and network connections are increasingly consumed as-a-service, by apps.

So the purpose of IT has been transformed from being an operator of apps, to an operator of services to power them. What's different about being a provider of IT services, rather than an operator of applications?

  1. It's about scale.
  2. It's about efficiency.
  3. It's about speed.

Explaining the difference between scale-up, and scale-out, is beyond the scope of this article. But I encourage you to read Maged Michael's excellent summary of the topic[1]. Whether we're scaling the number of users, the amount of data, or the complexity of calculations required (or even if you're scaling all three) - the era of scale-up is drawing to a close.

So if we can't scale UP, we have to scale OUT - which means building multi-server distributed systems. These are notoriously tricky. (In fact, Google famously considers their expertise in this to be a key competitive advantage.) So when we've invested the work in developing a system for delivering a particular service, we're likely to try and get as many different apps to share that service as possible. This is the same type of thinking that encouraged object-oriented programming and object reuse - if we're all sharing the same system, we can invest more in making it as reliable and efficient as possible. I like to call this the "Warren Buffet" approach to enterprise architecture - put all your eggs in one basket, and then watch that damn basket!

So we can see that, as our businesses have become more and more dependent on IT apps, those apps have in turn become more and more dependent on scalable, efficient services. And as applications have gotten both larger and more complex, IT has had to focus more on the services that can power these applications - rather than just the applications themselves.

Now, technology doesn't necessarily make life better. Nor does it reduce the number of mistakes we make. But it *does* help us go faster, which means we can make mistakes at a faster and faster rate. And this is what it's done in business, too - IT has sped everything up.

The pursuit of speed in IT has been transforming everything about how we develop software over the past ten years. It started with our project management methodologies, switching from traditional SDLC approaches to Agile ones such as Scrum or Kan-Ban. As we sped development up, we needed to integrate and test our systems earlier, and the Continuous Integration ecosystem was born, with tools such as Jenkins and Build Bot at the heart of it. Eventually, the need for speed broke through from development and testing, into the production operations environments, and the DevOps movement was born. We're starting to see a raft of tools and technologies to support Continuous Deployment now - the most mature form of DevOps.

The final step in this metamorphosis is a revolution in the delivery of the underlying infrastructure services - the push to API-driven, or software-defined, ...well, everything. Only when Continuous Infrastructure supports the Continuous Deployment of Continuously Integrated and Continuously Prioritized apps and features, will our work be complete.

With more than 30 Kubernetes solutions in the marketplace, it's tempting to think Kubernetes and the vendor ecosystem has solved the problem of operationalizing containers at scale or of automatically managing the elasticity of the underlying infrastructure that these solutions need to be truly scalable. Far from it. There are at least six major pain points that companies experience when they try to deploy and run Kubernetes in their complex environments. In this presentation, the speaker will detail these pain points and explain how cloud can address them.
Discussions of cloud computing have evolved in recent years from a focus on specific types of cloud, to a world of hybrid cloud, and to a world dominated by the APIs that make today's multi-cloud environments and hybrid clouds possible. In this Power Panel at 17th Cloud Expo, moderated by Conference Chair Roger Strukhoff, panelists addressed the importance of customers being able to use the specific technologies they need, through environments and ecosystems that expose their APIs to make true change and transformation possible.
"Space Monkey by Vivent Smart Home is a product that is a distributed cloud-based edge storage network. Vivent Smart Home, our parent company, is a smart home provider that places a lot of hard drives across homes in North America," explained JT Olds, Director of Engineering, and Brandon Crowfeather, Product Manager, at Vivint Smart Home, in this SYS-CON.tv interview at @ThingsExpo, held Oct 31 – Nov 2, 2017, at the Santa Clara Convention Center in Santa Clara, CA.
We are seeing a major migration of enterprises applications to the cloud. As cloud and business use of real time applications accelerate, legacy networks are no longer able to architecturally support cloud adoption and deliver the performance and security required by highly distributed enterprises. These outdated solutions have become more costly and complicated to implement, install, manage, and maintain.SD-WAN offers unlimited capabilities for accessing the benefits of the cloud and Internet. SD-WAN helps enterprises to take advantage of the exploding landscape of cloud applications and services, due to its unique capability to support all things cloud related.
In an era of historic innovation fueled by unprecedented access to data and technology, the low cost and risk of entering new markets has leveled the playing field for business. Today, any ambitious innovator can easily introduce a new application or product that can reinvent business models and transform the client experience. In their Day 2 Keynote at 19th Cloud Expo, Mercer Rowe, IBM Vice President of Strategic Alliances, and Raejeanne Skillern, Intel Vice President of Data Center Group and GM, discussed how clients in this new era of innovation can apply data, technology, plus human ingenuity to springboard to advance new business value and opportunities.
