Outlook 2013: Enterprise Will Seek a Better Network to the Cloud

The network is key for cloud use tomorrow

In 2012, much of the industry was focused on what's going inside the data center to enable cloud computing. As we move into 2013 and beyond, enterprise IT will need to consider the network that connects the data centers - particularly how these inter-data center networks need to change to support new cloud use cases and associated network requirements for bandwidth scalability, low latency, security, virtualization and automation. As network specialists, Ciena has been concentrating on solving the connectivity issues between data centers, and data centers to the cloud.

There are multiple reasons for this. First, enterprise IT organizations are highly motivated to drive efficiencies. Enterprise is already deriving efficiencies from its network - first through data center consolidation, then virtualization. The cloud promises to offer up to 25 percent infrastructure savings on IT services and hardware expenses, according to some studies. In turn, the network is also a key enabler for cloud service providers to operate multiple data centers as a shared pool of virtual data centers. We've found through our own research that this can enable a 35 percent reduction in total cloud data center resources.

Second, the use of cloud services is still in its infancy at many enterprises. Cloud software and infrastructure-as-a-service applications today live in the service provider cloud, often locked behind semi-proprietary architectures. As cloud deployments get more sophisticated, IT will need to deploy a more open architecture with standards in place for APIs and management tools. By doing this, they will be able to unlock the potential to federate private data centers with multiple provider cloud data centers, enabling greater workload mobility and the ability to deploy entirely new applications - this will require a better network to run effectively.

How the Cloud Is Used Today
Enterprise today typically uses cloud infrastructure for simple storage backup to cloud data centers over low speed IP networks, trickling the data asynchronously as the network permits in a north-south traffic flow from user-to-machine that moves over a tiered IP network architecture.

Tomorrow, the enterprise will want to take advantage of lower cost cloud storage for large amounts of storage. It will want a network that can dynamically respond to moving terabytes when the data needs to move - without bottlenecks, security holes or dropped packets. This will require east-west traffic flows from machine-to-machine within, and increasingly between, data centers. Such traffic has much more stringent quality-of-service requirements.

In the near future, we'll see at least an order of magnitude more east-west data workloads driven by applications like storage synchronization, inter-data center storage virtualization and virtual machine migrations. This means the cloud network needs to be designed for performance to meet the traffic flow change and intensity challenges of the future. For example, a flatter Layer 0/1/2 network architecture between data centers would deliver better scalability, latency and deterministic performance. With this architecture, the network won't be a bottleneck when it's needed the most, and it will deliver the lowest cost per bit throughput.

The Network Is Key for Cloud Use Tomorrow
As enterprise use of the cloud becomes more prominent, IT will look for ways to automate cloud use cases using an intelligent network. Software defined networking (SDN) is the key to achieving greater flexibility and lower costs. Workload orchestration between cloud data centers, and between enterprise and cloud data centers, will be driven by policy-based software automation tools. On-demand change in performance parameters such as bandwidth scalability will be accomplished through high-level software interfaces into the network control planes, not by an operator using a command line interface to the equipment. This performance-on-demand will be triggered at the application level, ensuring that the adjustments to the network and to the cloud meet the business requirements. In order for this to happen, the network will need to become an integral part of the entire cloud framework - it is the key ingredient that ties everything together, serving as a backplane across the data centers for flexible delivery of applications and services.

Inter data center networks need to become virtual, too. A virtualized network partitions resources in many different ways, e.g., virtual circuits (EVPLs), virtual wavelengths (Optical Transport Network - OTN); virtual switches (VSIs) and virtual networks (VPNs, Optical Virtual Private Network - OVPNs). Virtualization of the network provides network efficiency, i.e., coordination of the bandwidth and topology to the specific application need at a point in time. This eliminates the need to size all data center network interconnection facilities for a peak capacity that is only rarely used, which lowers costs because you don't need to make unnecessary network equipment investment.

A Virtual Data Center Architecture Will Deliver a Data Center Without Walls
A virtual data center architecture - "A data center without walls" - will deliver cost savings and operational efficiency. At Ciena, we are leveraging our networking expertise to deliver a "Data Center Without Walls" architecture for our customers that creates a multi-data center, hybrid cloud environment able to function as a set of virtual data centers from a common resource pool to address any magnitude of workload demand and offer seamless workflow movement. Enterprises will be able to access cloud resources anywhere, anytime. Service providers will be able to offer cloud services differentiated by state-of-the-art, programmable network access, and economies of scale that leverage their data center footprints. Cloud providers will be able to handle uncertain demand requirements and failover by more efficiently allocating workloads across multiple data centers. This cloud backbone network will be the critical link for providing cost-effective scalability, security, and on-demand services that enable the virtual data center.

Some journey to cloud on a mission, others, a deadline. Change management is useful when migrating to public, private or hybrid cloud environments in either case. For most, stakeholder engagement peaks during the planning and post migration phases of a project. Legacy engagements are fairly direct: projects follow a linear progression of activities (the “waterfall” approach) – change managers and application coders work from the same functional and technical requirements. Enablement and develo...
For DevOps teams, the concepts behind service-oriented architecture (SOA) are nothing new. A style of software design initially made popular in the 1990s, SOA was an alternative to a monolithic application; essentially a collection of coarse-grained components that communicated with each other. Communication would involve either simple data passing or two or more services coordinating some activity. SOA served as a valid approach to solving many architectural problems faced by businesses, as app...
The “Digital Era” is forcing us to engage with new methods to build, operate and maintain applications. This transformation also implies an evolution to more and more intelligent applications to better engage with the customers, while creating significant market differentiators. In both cases, the cloud has become a key enabler to embrace this digital revolution. So, moving to the cloud is no longer the question; the new questions are HOW and WHEN. To make this equation even more complex, most ...
The past few years have brought a sea change in the way applications are architected, developed, and consumed—increasing both the complexity of testing and the business impact of software failures.

However, Kubernetes may seem intimidating and complex ...
Gaining visibility in today’s sprawling cloud infrastructure is complex and laborious, involving drilling down into tools offered by various cloud services providers. Enterprise IT organizations need smarter and effective tools at their disposal in order to address this pertinent problem. Gaining a 360 - degree view of the cloud costs requires collection and analysis of the cost data across all cloud infrastructures used inside an enterprise.
You know you need the cloud, but you’re hesitant to simply dump everything at Amazon since you know that not all workloads are suitable for cloud. You know that you want the kind of ease of use and scalability that you get with public cloud, but your applications are architected in a way that makes the public cloud a non-starter. You’re looking at private cloud solutions based on hyperconverged infrastructure, but you’re concerned with the limits inherent in those technologies.
Gone are the days when application development was the daunting task of the highly skilled developers backed with strong IT skills, low code application development has democratized app development and empowered a new generation of citizen developers. There was a time when app development was in the domain of people with complex coding and technical skills. We called these people by various names like programmers, coders, techies, and they usually worked in a world oblivious of the everyday pri...
Our work, both with clients and with tools, has lead us to wonder how it is that organizations are handling compliance issues in the cloud. The big cloud vendors offer compliance for their infrastructure, but the shared responsibility model requires that you take certain steps to meet compliance requirements. Which lead us to start poking around a little more. We wanted to get a picture of what was available, and how it was being used. There is a lot of fluidity in this space, as in all things ...
The dynamic nature of the cloud means that change is a constant when it comes to modern cloud-based infrastructure.

Delivery automation helps IT Ops teams ensure that apps are providing an optimal end user experience over hybrid-cloud and multi-cloud environments, no matter what the current state of the infrastructure is. To employ a delivery automation strategy that reflects your business rules, making r...
The notion of improving operational efficiency is conspicuously absent from the healthcare debate - neither Obamacare nor the newly proposed GOP plan discusses the impact that a step-function improvement in efficiency could have on access to healthcare (through more capacity), quality of healthcare services (through reduced wait times for patients) or cost (through better utilization of scarce, expensive assets).
Admiral Calcote - also known as Lee Calcote (@lcalcote) or the Ginger Geek to his friends - gave a presentation entitled Characterizing and Contrasting Container Orchestrators at the 2016 All Day DevOps conference.

You could also say that they are like the conductor of an orchestra, directing...
Cloud Governance means many things to many people. Heck, just the word cloud means different things depending on who you are talking to. While definitions can vary, controlling access to cloud resources is invariably a central piece of any governance program. Enterprise cloud computing has transformed IT. Cloud computing decreases time-to-market, improves agility by allowing businesses to adapt quickly to changing market demands, and, ultimately, drives down costs.
Recent survey done across top 500 fortune companies shows almost 70% of the CIO have either heard about IAC from their infrastructure head or they are on their way to implement IAC. Yet if you look under the hood while some level of automation has been done, most of the infrastructure is still managed in much tradition/legacy way. So, what is Infrastructure as Code? how do you determine if your IT infrastructure is truly automated?
Every few years, a disruptive force comes along that prompts us to reframe our understanding of what something means, or how it works. For years, the notion of what a computer is and how you make one went pretty much unchallenged. Then virtualization came along, followed by cloud computing, and most recently containers. Suddenly the old rules no longer seemed to apply, or at least they didn’t always apply. These disruptors made us reconsider our IT worldview.
As people view cloud as a preferred option to build IT systems, the size of the cloud-based system is getting bigger and more complex. As the system gets bigger, more people need to collaborate from design to management. As more people collaborate to create a bigger system, the need for a systematic approach to automate the process is required. Just as in software, cloud now needs DevOps. In this session, the audience can see how people can solve this issue with a visual model. Visual models ha...
