As an SDN network provider focused on the datacenter, we spend a good amount of time understanding the state of data centers today, tomorrow and some time into the future.
There is no question that the use of Software as a Service (SaaS) applications in the cloud is growing rapidly. Plexxi itself is a shining example, few of the applications we use are in-house across all functional areas.
There are many reasons why we picked cloud-based applications for our needs. As a small company, in many cases there is a very simply economic choice to make. Paying for a cloud based service is simply cheaper than building your own infrastructure. Creating a datacenter infrastructure is not cheap, and maintaining it and the applications that run on top is a serious investment. When you are small, that overhead is hard to carry and per user based charges for a cloud based application is much easier to swallow.
But as small as we are, we have clear needs for in house datacenter resources, and we are not in a very compute or storage intensive business. We have built a mini datacenter in our test environment. This is where we do our scaling tests, our integration testing with external systems, and even run big data applications as part of the test and development cycle. We have a growing environment where we validate larger and larger systems through simulation.
We are extremely focused to make sure that all our applications are as tightly integrated as they can be. We constantly chase our application providers for hooks and integrations that allow us to create a seamless environment with clear workflows from one application to another. Some of these integrations can only be done on non cloud based versions of the applications we use. Our use of some of these applications is heavy enough that access performance is becoming an issue. Productivity loss is hard to measure but very real.
There is no doubt in my mind that we will continue to grow our own datacenter. There are some things we have to run in house to ensure a controlled environment with dedicated access, others will be more hybrid with local cache and proxy versions for cloud based applications.
This week I read this article where Intel’s CIO Kim Stevenson talks about Intel’s own datacenter infrastructure. Of course Intel is somewhat unique in the sense that they create one of the most critical pieces of datacenter resources, but really they are a big multinational like so many others that have compute and storage needs for their business.
In the article, Kim articulates some of the key reasons why the enterprise datacenter will not disappear. A direct quote: “That’s because the company runs mission-critical applications for developing intellectual property, manufacturing, customer service, and product development, and thus far, these work better internally”, followed by “the company is very sensitive about its proprietary data”. In just two quotes, these are key reasons to have certain things in-house. Access, performance, flexibility, customization, security, locality. The first few will improve with better cloud environments and access to them, but those last few will have a much higher resistance.
The size of Intel’s datacenters is quite impressive. 630,000 Xeon cores across 50,000 servers. And their utilization close to 90% throughout the day. That would be one heck of a compute workload to place into the cloud. Yes, Intel is large. But there are so many others like them, some with perhaps even heavier compute and storage requirements than Intel. Large pharmaceuticals performing chemical research and analysis, oil and gas companies feeding huge amounts of data into their compute centers in search of natural resources, banks, insurance companies and credit card companies storing millions and billions of transactions and try to find patterns in an attempt to understand us better and sell us more.
There is no question that many of our applications will move to the cloud. Pure economics will drive that. But at the same time there will continue to be resistance for a long time to come to move certain applications and data into the cloud. And as Intel’s numbers show, those are very significant amounts of resources.
The enterprise datacenter will continue to exists and grow for a long time to come. Where and how we run our applications will show a shift of applications into the cloud. The boundary between local and cloud will blur, with some applications fully in the cloud, others fully local, and many in a hybrid between the two for performance, security, scaling or elasticity reasons. And it is there that we as an industry creating datacenter infrastructures need to focus.

In high-production environments where release cycles are measured in hours or minutes — not days or weeks — there's little room for mistakes and no room for confusion. Everyone has to understand what's happening, in real time, and have the means to do whatever is necessary to keep applications up and running optimally. DevOps is a high-stakes world, but done well, it delivers the agility and performance to significantly impact business competitiveness.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com...

The move in recent years to cloud computing services and architectures has added significant pace to the application development and deployment environment. When enterprise IT can spin up large computing instances in just minutes, developers can also design and deploy in small time frames that were unimaginable a few years ago. The consequent move toward lean, agile, and fast development leads to the need for the development and operations sides to work very closely together. Thus, DevOps become...
