The data centers of the future may look more like NASA ground control – governance inside, resources out

The data centers of the future may look more like NASA ground control – governance inside, resources out

One theme has remained consistent throughout the evolution of cloud thus far - enterprise IT wants to retain control of both its data and access to to it.

This is not an unreasonable demand. After all, it is enterprise IT - and its leadership - that will pay the price should customer data leak or regulations not complied with. Despite the growing view that cloud security is a joint, shared responsibility between customer and provider, it is enterprise IT that must put into place the mechanisms for both controlling and proving control over data and access, not cloud providers or integrators. The provider can offer services designed to provide that control, but it is not the one that must implement the polices or report on their effectiveness.

Amazon throws down the gauntlet for enterprise IT

While a collaboration and file-sharing app has been moved to AWS, access controls have to remain in-house, according to Oliver Alvarez, lead enterprise security architect for the World Bank's International Finance Corporation.

"We need to maintain control and custodianship of information," he said.

Access control by its nature must include identity management. Without the means to manage the credentials and map authorization of access to data and services to those credentials, control is lost. If customer data is the lifeblood of an organization, identity stores are the heart's valves, controlling when and where that data is moved and by whom.

TWO EMERGING ARCHITECTURES

Two architectures for control over identity and access are beginning to emerge, both having a common premise - identity stores are local, data and services are remote. In one architecture a provider - usually of a SaaS solution - deploys a virtual appliance on premise that brokers identity. This essentially enables LDAP/AD integration between the data center and the SaaS. In the second, a strategic control layer acting as a cloud services broker provides integration between environments using standard protocols, such as SAML, to enable control over authentication and authorization of cloud services.

The appliance model is an extension of agent-based services, merely expanded to the data center level. There are some concerns that go along with this model, chiefly that an external entity has control of an agent within the data center but in general this models appears to enjoy market acceptance, especially in cases where a standards-based approach is unavailable.

The alternative, standards-based model, uses the same brokering model but the broker is under the control of enterprise IT, not the provider. It relies on the same principles of abstraction we've come to recognize with virtualization and SDN as being beneficial to agility in the network and data center, putting a layer of control between resources and users so as to enable more flexibility in not just access control and identity management but in making routing decisions with respect to those resources.

That layer of control within enterprise IT is unlikely to go away for the very reasons cited above: control (governance) is a legal and operational necessity for enterprise IT. Cloud providers who fail to recognize this need and move to provide services supportive of that necessity are merely shooting themselves in the foot with respect to gaining more traction with enterprise customers.

Cloud gateways and broker services are going to end up enabling this architecture on the enterprise side. It is in providers' best interests to make these architectures as painless to implement as possible.

After more than five years of DevOps, definitions are evolving, boundaries are expanding, ‘unicorns’ are no longer rare, enterprises are on board, and pundits are moving on. Can we now look at an evolution of DevOps? Should we? Is the foundation of DevOps ‘done’, or is there still too much left to do? What is mature, and what is still missing? What does the next 5 years of DevOps look like? In this Power Panel at DevOps Summit, moderated by DevOps Summit Conference Chair Andi Mann, panelists l...
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 abi...
The essence of cloud computing is that all consumable IT resources are delivered as services. In his session at 15th Cloud Expo, Yung Chou, Technology Evangelist at Microsoft, demonstrated the concepts and implementations of two important cloud computing deliveries: Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). He discussed from business and technical viewpoints what exactly they are, why we care, how they are different and in what ways, and the strategies for IT to transi...
Thanks to Docker and the DevOps revolution, microservices have emerged as the new way to build and deploy applications — and there are plenty of great reasons to embrace the microservices trend. If you are going to adopt microservices, you also have to understand that microservice architectures have many moving parts. When it comes to incident management, this presents an important difference between microservices and monolithic architectures. More moving parts mean more complexity to monitor an...
All organizations that did not originate this moment have a pre-existing culture as well as legacy technology and processes that can be more or less amenable to DevOps implementation. That organizational culture is influenced by the personalities and management styles of Executive Management, the wider culture in which the organization is situated, and the personalities of key team members at all levels of the organization. This culture and entrenched interests usually throw a wrench in the work...
Microservices (μServices) are a fascinating evolution of the Distributed Object Computing (DOC) paradigm. Initial design of DOC attempted to solve the problem of simplifying developing complex distributed applications by applying object-oriented design principles to disparate components operating across networked infrastructure. In this model, DOC “hid” the complexity of making this work from the developer regardless of the deployment architecture through the use of complex frameworks, such as C...

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" ...

In recent years, containers have taken the world by storm. Companies of all sizes and industries have realized the massive benefits of containers, such as unprecedented mobility, higher hardware utilization, and increased flexibility and agility; however, many containers today are non-persistent. Containers without persistence miss out on many benefits, and in many cases simply pass the responsibility of persistence onto other infrastructure, adding additional complexity.
