How Software Defined Networking Delivers Next-Generation Success

Wednesday, June 5th, 2013 by

Software defined networking (SDN) is today where the cloud was a few years ago, and their paths are quite similar. As cloud providers innovate, they incorporate new, cutting-edge technology to let users do more with their architectures and enable solutions that were previously impossible. Just as the cloud moved people away from physical boxes and bare metal devices, SDN is allowing developers and architects to divorce themselves from proprietary hardware appliances like load balancers and firewalls.

So, what are the similarities between SDN and cloud? How about abstraction or the movement from physical to virtual?

To get a bit more scientific, I jumped over to Google Trends (which looks at search term volume over time) and did a search for “cloud,” “SDN,” “cloud computing,” and “software defined networking.”

The results shown here make it pretty obvious that “cloud” continues to grow and overshadow the other terms. Removing “cloud” shows “SDN” making the same upward trajectory as “cloud” does in the graphic below. (Because people have been shortening the term “cloud computing” to simply “cloud,” it’s logical that the term’s search volume is decreasing.)

SDN activity grows, stirs IT network innovation

Friday, May 24th, 2013 by

The software defined networking (SDN) market is new, which is why analysts and the media have varying perspectives on the strategy. For the most part, experts believe SDN is no passing fad and will continue to influence the enterprise architecture in the coming years. At the same time, however, experts believe SDN is still relatively young and in a conceptual stage, meaning developing a project with strong return on investment figures may not yet be possible.

SDN activity grows, stirs IT network innovation

A recent InformationWeek highlighted how SDN promises to deliver similar benefits to cloud computing, including greater infrastructure flexibility, increased utilization of network capacity and reduced operating expenses. While these “promises” are still in theory, largely because SDN has not reached its full adoption yet, the strategies will likely change the status quo in the coming years.

“Today, security, routing and energy management are dictated by the box,” said Nick McKeown, an SDN visionary and Stanford professor, according to InformationWeek. “That’s why the infrastructure hasn’t changed for 40 years.”

While the infrastructure landscape has changed, thanks to the proliferation of virtualization and cloud technologies, networks have long been more traditional. Fortunately, this is changing, as 26 percent of companies are either testing SDN or will have completed its analysis within 12 months, while 4 percent are already finished with the examination phase and have put SDN in production, the news source reported.

SDN improves speed and flexibility
While there are a number of benefits associated with SDN, roughly 66 percent of businesses said the ability to speed up delivery and have a more efficient and flexible network was the top selling point, InformationWeek noted. This is largely because the way companies provision resources needs to change.

Advertising in the Cloud

Thursday, May 2nd, 2013 by

If you’re an online advertising company, you know how important it is to have infrastructure that performs and is resilient, reliable, and available globally. You want to spend your time optimizing your ad delivery across the world, developing your delivery platform, and not on worrying about whether your infrastructure can deliver your content quickly and accurately.

We get advertising. We all click on an online ad or read the messaging or watch the videos. We have customers that are pushing the technology envelope to deliver their advertising to end users. And many of our advertising customers have complex cloud infrastructure powering their platforms.

Advertising in the Cloud - Ad Network architecture

From Big Data architectures to Content Delivery Networks (CDNs) to multi-data-center deployments, our solutions are carefully designed to meet the unique needs of advertising providers. And although you could do it all yourself in our global cloud, we view ourselves as your partner. Our Solutions Architects are available to help you identify the best services we provide for crafting your advertising delivery platform.

How To Enable & Manage the New, Free GoGrid Firewall Service

Wednesday, May 1st, 2013 by

Security and infrastructure don’t always go hand in hand. In fact, many non-adopters of cloud computing have cited the lack of good security as one of the primary reasons they are not wholeheartedly embracing the cloud and all its glory. In some ways, these naysayers are correct: You shouldn’t deploy a cloud or frankly any type of infrastructure without some type of security, whether it’s software-based controls or a hardware device. At GoGrid, it is this desire to overcome security concerns that compelled us to release our free (that’s right FREE) Firewall Service.

When we developed our Firewall Service, we wanted to do more than simply offer a set of blocking rules or a hardware device. We wanted our solution to be centrally managed, easy to use and configure, fully featured, integrated across all our data centers, reliable, programmatically controlled, highly available, flexible, elastic, self-healing…whew! And did I mention, free? As we did for our new Dynamic Load Balancers, we embraced the concepts of software-defined networking (SDN) when architecting our Firewall Service.

Our research showed that for small environments, software-based firewalls (like IPtables or a Windows Firewall) worked just fine, provided the infrastructure didn’t need to scale. Similarly, hardware-based firewalls were great for enterprise-grade installations (but remember, if you get one hardware device, you typically need another one ready as a failover). We wanted to do it better. You can read more about the theory behind our cloud Firewall Service in this article.

As with my previous How To articles, there are 3 easy steps in the Firewall Service setup:

1. Create a Security Group
2. Define
a Policy
3. Add
a Connection

GoGrid’s Firewall Service is distributed and global. That means that once it’s configured, it automatically synchronizes across all our data centers. If you have multiple web servers in multiple GoGrid data centers, you simply define the Security Groups and Policies, connect the servers, and you’re done. Any future policy changes are automatically synchronized to the connected servers. Simple, right? Let’s see how to set up the Firewall Service.

Is Your High-Tech Company Ready For An SDN-Enabled Cloud?

Thursday, April 18th, 2013 by

When it comes to technology, there are many companies on the “bleeding edge” these days. Sometimes these companies achieve greatness by being visionary, producing products or services that others haven’t thought of, or investing heavily in R&D. But they all have one thing in common: They use the latest high-tech, innovative solutions to power their journeys.

When it comes to the underlying infrastructure powering a technology-oriented company, “cutting edge” means success. Sites and services need to perform, be reliable, be resilient, and have the flexibility to expand and contract based on the ebb and flow of day-to-day business. For me, that means cloud infrastructure is the best solution for companies looking to stay ahead of the curve.

Over the past few months, GoGrid has released a variety of services and features designed to give companies a leg up on the competition. It’s all centered on providing cloud infrastructure that’s flexible, yet forward-thinking. It’s much more than simply needing faster and bigger clouds—it’s about architecting our cloud solutions to provide customers with a highly available and distributed set of infrastructure components. And it’s architected according to software-defined networking (SDN) concepts.

SDN architecture isn’t focused on internetworked commodity hardware or new ways to provide networking services. It’s designed to distribute a variety of formerly hardware-based solutions across nodes, data centers, and clouds. When you think about “old school” infrastructure architecture, you probably think of physical devices. And if you think about one device, you really need to think about two, for redundancy and backup. If your hardware load balancer or firewall fails, you have to be sure you have a warm or hot standby available to immediately take its place. That requires time and money. And if you want to be cutting edge, you don’t want to be spending your precious time and money planning for the inevitable. You want to be innovating and iterating.

That’s where SDN is truly powerful and why many of the leading technology companies are adopting solutions that use it. With SDN, you can build in fault tolerance and redundancy. Take our recently released Dynamic Load Balancers as an example. Instead of relying on a single hardware device for routing traffic between available servers, our Dynamic Load Balancers are distributed and highly available across our Public Cloud. If one of the Dynamic Load Balancers fails, another instance, complete with configurations, is spawned immediately elsewhere thanks to our self-healing design. And these load-balancing services can be controlled programmatically via our API.

This month we announced another service that operates in the same distributed manner, our Firewall Service. Although many companies choose to use Cisco ASAs as a security front end for their cloud and physical infrastructure environments (an offering we also provide), these are physical devices that require management. However, our SDN architecture lets us provide more resilient and creative solutions. Like our Dynamic Load Balancers, our Firewall Service is built around SDN concepts and distributed across nodes and our data centers. When you create a security group (that has policies assigned to it), it’s automatically replicated across all our data centers within seconds. If you have distributed infrastructure, you can simply assign a security group to any similarly configured Cloud Server, regardless of that server’s location. If you subsequently change a policy, it’s automatically synchronized to all servers across all data centers that are part of that security group. In other words, you configure once, assign the security group to the server(s), and then watch the SDN magic happen.
