The Limits of Cloud: NICS and Nets

Cloud is great at many things. At other things, not so much

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.

Software delivery was once specific to the IT industry. Now, Continuous Delivery pipelines are used around world from e-commerce to airline software. Building a software delivery pipeline once involved hours of scripting and manual steps–a process that’s painful, if not impossible, to scale. However Continuous Delivery with Application Release Automation tools offers a scripting-free, automated experience. Continuous Delivery pipelines are immensely powerful for the modern enterprise, boosting ...
Using new techniques of information modeling, indexing, and processing, new cloud-based systems can support cloud-based workloads previously not possible for high-throughput insurance, banking, and case-based applications.

DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

We call it DevOps but much of the time there’s a lot more discussion about the needs and concerns of developers than there is about other groups. There’s a focus on improved and less isolated developer workflows. There are many discussions around collaboration, continuous integration and delivery, issue tracking, source code control, code review, IDEs, and xPaaS – and all the tools that enable those things. Changes in developer practices may come up – such as developers taking ownership of code ...
The proper isolation of resources is essential for multi-tenant environments. The traditional approach to isolate resources is, however, rather heavyweight. In his session at 18th Cloud Expo, Igor Drobiazko, co-founder of elastic.io, drew upon his own experience with operating a Docker container-based infrastructure on a large scale and present a lightweight solution for resource isolation using microservices. He also discussed the implementation of microservices in data and application integrat...
I’m told that it has been 21 years since Scrum became public when Jeff Sutherland and I presented it at an Object-Oriented Programming, Systems, Languages & Applications (OOPSLA) workshop in Austin, TX, in October of 1995.

I’m still in the same building and at the same company where I first formulated Scrum.[1] Initially nobody knew of Scrum, yet it is now an open source body of knowledge translated into more than 30 languages[2] People use Scrum worldwide for ...
Much of the value of DevOps comes from a (renewed) focus on measurement, sharing, and continuous feedback loops. In increasingly complex DevOps workflows and environments, and especially in larger, regulated, or more crystallized organizations, these core concepts become even more critical.

As the race for the presidency heats up, IT leaders would do well to recall the famous catchphrase from Bill Clinton’s successful 1992 campaign against George H. W. Bush: “It’s the economy, stupid.” That catchphrase is important, because IT economics are important. Especially when it comes to cloud. Application performance management (APM) for the cloud may turn out to be as much about those economics as it is about customer experience.
