Understanding the limitations of cloud will better enable a successful migration strategy.
You might have noticed that in general, enterprise-grade networking solutions aren't always available for general deployment in public cloud environments.
You might also have noticed that when you provision a compute instance in a public cloud environment you get one public (and usually one private) IP address.
I'll stop for a moment and let you consider the relationship between these two facts.
Many mature enterprise-grade networking solutions require at least two network interfaces – one for traffic (data plane) and one for management (control plane) and often suggest a third for optimal, best-practice deployment. It's been a long time since I've seen mature networking solutions that don't employ segregated management networks. Those solutions that sit inline and that are in the line of fire, as you will, from concentrated network and application-layer attacks, absolutely need segregated management as a means to control the solution and mitigate an in-progress attack or sudden spike in utilization that might be overwhelming the primary network.
The use of a separate management network also ensures that the control plane is secured from general access.
Generally speaking, it's been considered a best-practice to use a separate, secured management network for critical network components since the web exploded.
Unfortunately, most cloud environments don't support this capability for customers. While certainly cloud is the largest example of control-data plane separation, such environments are designed to transport control of provider functions and service-control, not customer-deployed solutions. Thus the instances provisioned by the customer are expected to exist on the data plane because management functions (control plane) are handled through the provider's framework / API.
That means vendors of mature, enterprise-grade networking solutions have few options for cloud-enabling their solutions when NICs (and networks) are limited. Amazon EC2 is one such environment; it currently does not support multiple IP addresses per instance. Simply AMI-enabling a networking solution that requires a separate management network is not going to be enough.
That's why you see enterprise-class networking solutions becoming available for Amazon AWS, but only in its Virtual Private Cloud (VPC) environment. In the VPC environment instances are able to take advantage of more advanced networking capabilities familiar to enterprise operations such as control over IP address ranges, creation of subnets, and configuration of routes and network gateways.
Rackspace, on the other hand, is moving toward enabling multiple networks capable of broadcasting and multicasting through its evolving support for OpenStack. Such capabilities will enable customers to take advantage of mature networking solutions within its environment. There are restrictions, of course, as will be the case with any provider, but in general such a move toward enabling advanced networking within open cloud environments is a positive one.
What this all means is that when considering cloud providers and migration of applications (and their supporting infrastructure) it is critical to seek out and understand what advanced networking capabilities are – or aren't – available for each provider you are evaluating. Infrastructure support is a key component for many enterprise-class applications now being considered for migration to the cloud and not all clouds will be able to equally support the advanced networking services necessary.
As organizations shift towards IT-as-a-service models, the need for managing & protecting data residing across physical, virtual, and now cloud environments grows with it. CommVault can ensure protection & E-Discovery of your data - whether in a private cloud, a Service Provider delivered public cloud, or a hybrid cloud environment – across the heterogeneous enterprise.

Just over a week ago I received a long and loud sustained applause for a presentation I delivered at this year’s Cloud Expo in Santa Clara. I was extremely pleased with the turnout and had some very good conversations with many of the attendees. Over the next few days I had many more meaningful conversations and was not only happy with the results but also learned a few new things. Here is everything I learned in those three days distilled into three short points.

Culture is the most important ingredient of DevOps. The challenge for most organizations is defining and communicating a vision of beneficial DevOps culture for their organizations, and then facilitating the changes needed to achieve that. Often this comes down to an ability to provide true leadership. As a CIO, are your direct reports IT managers or are they IT leaders? The hard truth is that many IT managers have risen through the ranks based on their technical skills, not their leadership ab...

DevOps is about increasing efficiency, but nothing is more inefficient than building the same application twice. However, this is a routine occurrence with enterprise applications that need both a rich desktop web interface and strong mobile support. With recent technological advances from Isomorphic Software and others, rich desktop and tuned mobile experiences can now be created with a single codebase – without compromising functionality, performance or usability. In his session at DevOps Su...

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.

Microservices are a very exciting architectural approach that many organizations are looking to as a way to accelerate innovation. Microservices promise to allow teams to move away from monolithic "ball of mud" systems, but the reality is that, in the vast majority of organizations, different projects and technologies will continue to be developed at different speeds. How to handle the dependencies between these disparate systems with different iteration cycles? Consider the "canoncial problem"...
